Description

The invention relates to a lighting surface with electrical, light-emitting Consumers, such as LED, SM-LED or organic semiconductors, consisting from a support surface in which the consumer is embedded or on the Support surface are attached.

Such a lighting surface with applied to glass light emitting diodes over essentially invisible conductor tracks applied to the glass surface a power connection are, for example, from EP 0995 1 99th known. The light-emitting diodes, for example produced in subminiature technology (SMD), can be controlled individually or in groups via this track and because of their small depth also between two glass plates protected against contact and contamination. The glass surfaces have one high specific gravity and are therefore not readily for the Covering large areas, for example in the facade area, because of high forces to intercept. A retrofitting of an existing facade, to Example with glass elements, is therefore very expensive.

From the motor vehicle sector are more or less visible and as a resistor trained ladder, which are connected to the rear window around a heated rear window to form. The ladder here does not serve the supply of electrical consumers, but represent even the consumer. The ladder can be flexible and - to facilitate assembly - first with one flexible film to be connected when mounting with the rear window is connected.

Translucent and transparent surfaces, especially as flexible surfaces, become often used in the prior art to form a weather protection, the Environmental influences, such as rain, wind, UV radiation and unwanted Keeps air exchange away. Such areas are used in tent construction, awning or used as umbrellas and are popular because they create large open spaces that optically open the room to the side or upwards. They also convey the Impression that one is staying in the open air. The disadvantage, however, is that in dark weather and night, the thus formed transparent surfaces, apart from a few unintended reflections or reflections, dark and appear black.

In interior design, exhibition construction and outdoor are for a long time so-called tension films made of PVC, which, with a circumferential piping provided, are stretched under heating, around them in circumferential rails mount. Upon cooling, they pull themselves under building a high tensile residual stress together. This results in very smooth ceilings or walls without visible sagging. Such surfaces are also translucent, that is Translucent but not translucent, available and used as a diffuser Example used for large area lights. For light design applications this Foils is the use of behind mounted bulbs, for example Fluorescent tubes, necessary, whereby a larger depth is needed. To In individual cases, creative purposes are also transparent in that is called clear films used, which are like glass transparent.

Object of the present invention is an improved lighting surface with electrical consumers to create more creative options offers.

According to the invention, this object is achieved in that the support surface is designed to be translucent and arranged the consumer so spaced are that at least partially sufficient ambient light is transmitted, so that the support surface is translucent on both sides. advantageous Embodiments are the subject of the dependent claims.

By the consumer, preferably bulbs in the form of LED, SM-LED or organic semiconductors, on the support surface creates a lighting surface with special optical effects. These range from individual points of light, over picture, script or pattern-like arranged points of light up to extensive radiation of light over the entire surface. The bulbs can be monochrome, colorful or color-tunable (for example RGB-LED) be. The bulbs can all together (rows / parallel), in Groups, or individually controllable. For single or groupwise Control of color-tunable bulbs is even one Color monitor similar operation or use as a color monitor possible, provided that the density of the lamps is selected accordingly. Apart from the special application as a color monitor, the bulbs can be spaced in such a way be arranged that on the one hand sufficient ambient light is transmitted and on the other hand, the support surface is translucent from both sides. Thus, pictorial motifs can be generated by the bulbs specifically can be used for large pictures, with several side by side arranged lighting surfaces to complement a large picture.

In a particularly advantageous embodiment of the invention, as Consumers, conductors, antennas, coils, capacitor surfaces, coils and The so-called "organic semiconductors" are used. Organic semiconductors, in particular of organic molecular crystals, have a high application potential for components such as diodes, transistors, photovoltaic cells and organic light-emitting diodes (OLEDs). Their commercial application remained for a long time limited to a few markets, for example, as photoconductive materials in Copiers. For about twenty years, the situation has changed drastically changed. By the discovery of electrically highly conductive polymers, the in particular also be used as a conductor within the meaning of the invention, sat down tremendous worldwide interest in organic semiconductors and their use in electronics and optoelectronics. Basis for the rapid progress were the synthesis of novel substances, the improved purity of these Materials, a controlled layer production, effective protection of the Substances and components from air and moisture, and above all, a steady growing understanding of the underlying physical processes. since recently, one is able to grow organic crystals whose charge carrier mobility no longer by defects, but just as in inorganic ones Crystals are limited by phonon scattering. Also succeeded, so fundamental Semiconductor properties such as the quantum Hall effect or electrically pumped Laser activity also in organic semiconductors. Even stronger than that Basic research has advanced application development. One is now able to produce organic light emitting diodes in all colors shine efficiently and long-lasting. Meanwhile, there are even first full-color flat screens from organic materials. In addition, succeeded organic To produce transistors whose switching speed comparable to that of Thin-film transistors (TFT) made of amorphous silicon are used in today's LCD screens Since the components of plastics are relatively easy to manufacture, now opens up a huge range of promising Products ranging from transistors and plastic chips to high-definition, full color flat screens to lasers.

The organic light-emitting diode (OLED) is constructed, for example, as follows: A transparent one Substrate (glass, quartz or polymer film) serves as the basis for the structure. The Anode, an ITO (indium tin oxide) layer is electrically conductive and for visible light permeable. The light is created in the "active" organic Layers, when there recombine pairs of electrons and "holes" and each generate a photon. The light gets through the optically transparent Substrate radiated. In order to achieve a high efficiency, for the Transport of charge carriers applied one or more additional layers. Finally, as the cathode, an optically non-transparent metal contact with low work function (for example, calcium) vapor-deposited. When creating an external voltage of less than 5 volts between the cathode and the anode it comes to the emission of light, the color of which is active Materials depends. In addition to the schematic structure of an OLED are the chemical structures of common active materials indicated: spin coated polymeric compounds; evaporated low molecular weight materials. The Organic electroluminescence works very well, because of the nature of Cargo transport in disordered organic layers as well as high Fluorescence yield of organic molecules or polymer chains. The low mobility of the charge carriers ensures that the once formed electron-hole pairs can cover only small distances, before they recombine and emit light. Thus, the danger is low that they encounter a structural defect or an impurity and there without light emission disintegrated.

For transistors or electronic circuits, conductors, antennas, Coils, capacitor surfaces, coils and the like, however, you need a great mobility of the charge carriers and in addition high structural order of the Molecules in the organic layers, but perfect order prevails only in a single crystal. With organic single crystals, however, you lose some of the Advantages that the OLEDs have over conventional inorganic technology Semiconductors have, for example, simple and large-scale production, Robustness and flexibility. In organic transistor circuits promises Therefore, success does not come from a competition with established semiconductor technology, but with alternative solutions, for example, flexible transistor circuits, completely made of organic materials by means of pressure or Aufdampftechniken be produced and are very inexpensive. The necessary Order in the thin layers arises through self-organization of the organic Molecules at appropriately prepared boundary surfaces and surfaces. evaporated For example, if rod-shaped thiophene molecules are involved, they will be arranged accordingly Substrate and preparation standing vertically or lying flat. Also the chains different spin-coated polymers depend on the cooling from the liquid crystalline phase along a predetermined axis. Based on these In order to form well-conducting channels in the organic transistors. The Step from the simple component to the integrated circuit one has recently made: From the Bell laboratories in the US was a circuit with 864 presented organic transistors. Because this chip is made entirely of plastic exists, it can be bent without losing its functionality. The manufactured transistor circuit allows operating frequencies in the kHz range, as they are sufficient for "low-cost" electronics.

However, according to the invention, the illumination surface may also be defined by a mesh, a Matrix or other arrangement of conductors without a special continuous Surface can be formed for example of plastic or foil. A braid of preferably insulated thin conductors thus forms the skeleton on which the individual consumer or lighting means are attached. This can then be laminated for example between films or free in the Room to be hung up. Such a network is without sophisticated manufacturing processes easy to make.

In addition, a lighting surface in the sense of the invention can be any be any inventively designed 3-D object. For example Chairs, tables, plates, housings for technical devices, furniture, etc. can be produced, for example, by a hollow or solid translucent / transparent Housing, which refers to one of the following Species is provided with lighting. Especially unknown and exotic Lighting effects can be achieved if, in addition to the bulbs more refractive, light-reflecting or light-scattering particles, for example holographic particles, transparent particles of different refractive index etc. of the support surface are added. For example, an object may be off transparent synthetic resin with the addition of holographic foil particles, Glass particles and LEDs the optical effect described above achieve.

In addition, the lighting surface does not necessarily have to be in a flat shape be defined. For example, the invention is also as a flag, drooping Surface, such as roller blind, or even blind imaginable. Finally, too the arrangement of the lamps themselves in the area randomly and dynamically distributed be, as the following example shows. The wireless-controlled later described or energy-supplied bulbs are in one Floating liquid or floating, for example in a body of water, Swimming pool, pool, aquarium or a water-filled object, for example, a column made of glass or Plexiglas. The latter are known as decorative objects and typically have a height of 1.80 m and a diameter of 50 cm and are from below with headlights illuminated while illuminated from the ground area for generating illuminated Bubbles is blown. Wirelessly illuminable bulbs, for example Light-emitting diodes with dipole antenna or coils, float in the forming Flow and are provided by peripherally provided coils, in particular from the Substantially invisible or invisibly arranged ladders, Coils or antennas exposed to an electromagnetic field. The control can for example be done so that the bulbs only in a certain Range, for example, above, light up or in different zones one accept another color. Possibilities for the technical implementation of this Thought will be explained below. For example, the RGB light emitting diode multiple antennas, coils, dipole antennas, and the like have different resonance frequencies for each color.

If the illumination surface according to the invention as a film, in particular Tension film, for example made of PVC, can be particularly efficient, proven and inexpensive manufacturing processes, such as film blowing or extruder, are used. In an embodiment as Tension film or foil apply their known advantages in terms of Lightness, mountability, transportability and large area. The lighting area or film can be basically rigid or flexible and is preferably used even though curved film surfaces are not be excluded. Particular advantages are achieved when no Glass, especially because of its brittleness and its weight, processed becomes.

The invention also provides that with electrical consumers provided carrier surface is transparent or translucent. A transparent one Support surface in the sense of the invention means that they are the viewer in Essentially as transparent. It does not necessarily come down to that that the support surface provides an undistorted or completely clear view, for example, as with a clear glass, enabled. A transparent one Carrier surface in the context of the invention is especially when behind the Carrier surface located objects can be seen. Translucent against means that the support surface is translucent, that is, that one Illumination placed behind the support surface clears the space in front of the support surface quite able to illuminate, with the viewer behind the translucent However, carrier surface standing lighting can not detect in detail. A Ground glass is an example of a translucent surface according to the invention, the bulbs not at all or only schematically, for example as a bright zone, are recognizable. A translucent surface has the advantage of being behind it hidden technology, the electrical consumers, especially the bulbs, may also be hidden and, for example, only then perceived become active, for example, when they become active. A translucent surface So, when the bulbs are activated, they seem to be out, possibly even homogeneously over the entire surface. It may, in the Contrary to the large area light quite be desired that the Illuminate individually, ie individual more or less diffuse points form. Of course, the bulbs can also be on the visible side of the surface be arranged visible. Although the invention is mainly based on Light-emitting diodes, in particular subminiature light-emitting diodes and OLED, as an example for an electrical consumer, described. Correspondingly, that is Invention, however, to other electrical consumers, for example Sound sources, piezo, sensors, actuators, signalers and the like, apply. Subminiature light emitting diodes and OLEDs have the advantage of being because of the essentially missing housing have a smaller depth and still be easy to machine or produce by machine. Illuminated surfaces with a transparent or translucent Carrier surface have the advantage that the optical contact to another Room can be made by viewing or diffused outdoor light effect. When using the illumination surface according to the invention as for example Outside wall or outside roof, this lighting surface is permeable to daytime the natural light, which is pleasantly perceived by humans or even lets you look outside. At night, on the other hand, if the lighting surface would be dark overall and therefore the Room no longer limited in a reasonable way, the invention serves Lighting surface because of the bulbs as eye-catching and / or artificial Light source for the room. Of course, this application is also appropriate any two adjacent rooms or partitioned areas applicable and therefore not on the application described above (inside / outside) limited. The consumers can in this case to one side, preferably to be arranged on both sides of the support surface and consequently light to both Emit sides of the support surface.

If the lighting surface is flexible, it can be used as a roof, ceiling or Wall can be used and is therefore versatile, space-saving, rolled up and foldable. A flexible lighting surface is usually easier too mount and harder to damage than for example glass. The storage and transportation are also simplified. In addition, because of the Roll-up of a flexible lighting surface larger areas in one piece, that means without the application of multiple lighting surfaces to be realized. In addition, it may be possible for the lighting surface to be similar to an awning roll up when it is not needed. This opens application areas in the Outdoors. Suitable materials are for example PVC, as for example has been used as a stretch film for years in the field of stretch ceilings.

The bulbs are in the support surface or in a certain area of the Carrier surface arranged so that enough ambient light is transmitted, that means that for the viewer a consciously perceptible contact after Outside or in the other area is manufacturable, of course the brightness in front of the support surface has to be considered. At the same time creates a luminous or at least glittering support surface for the viewer. Of the According to the invention desired effect can be influenced by the impression of Starry sky with scattered luminous points up to a large, seemingly reach out from illuminating support surface. This applies to all Light situations, for example, in brightness and darkness, where the luminosity the bulb is interpreted accordingly.

In a further embodiment, it is provided that the electrical consumers are arranged on the support surface so that they are wireless, that is without direct electrical contact, are activatable. Activate means for example at a lighting means that the brightness state can be influenced, for example by dimming or switching on / off. The activation can be any bulbs or include individual groups. As a result, no disturbing tracks are visible or it must be no complicated laid, connected or be printed. The activation takes place in particular by wireless Transmission of energy necessary for operation or by wireless Influencing the switching state, whereby the energy required for lighting in the bulb is stored (for example, capacitor, battery), or on other way, for example via cables or tracks, available is provided. As a result, at least some of the wiring can be dispensed with which makes the manufacturing process easier and cheaper and especially with flexible and / or stretchable lighting surface a Breaking contact is at least less likely. examples for Wireless activation options are for example inductive and capacitive Coupling, light, radio or microwaves. The wireless coupling offers two Advantages: Where the coupling can work over long distances, for example Light, radio or microwaves, a wiring or the Applying conductor tracks to the illumination surface or carrier surface superfluous. Damage to the same and short circuits are basically not possible. On the other hand eliminates the application technology and manufacturing technology problematic contact point between conductor and electrical consumer. Such contacts usually have to be positive or non-positive or by Soldering, welding and the like can be produced. Every contact is one potential source of interference, weakens or damages the lighting surface or is not producible depending on the type of lighting surface (for example, soldering on a PVC film) and can oxidation, the ingress of liquids or subject to acids or galvanic influences. A wireless Coupling is also useful where the electrical conductors in the immediate Near the electrical consumers are introduced. The above Contact problems are avoided if the electrical consumer is only in the proximity of the conductor must be brought. The energy or Signal transmission can be very effective over short distances, for example done by inductive or capacitive coupling. For this purpose can So ladder or consumer side corresponding coil or Capacitor surfaces are formed, and it is not a problem if in between the illumination surface, support surface or other insulating Layer is.

A particularly simple way of activation is given when on both sides of the formed as an insulator support surface, such as a PVC film, a particular invisible, conductive material is applied. If This is subjected to different voltage can at any Place correspondingly used electrical loads powered become.

The storage of the necessary energy for lighting in the bulbs For example, about capacitors has the advantage that, for example, via a long period over very long distances or with very low energy the Energy can be transported and for a comparatively short flash / flash of the bulb can be used. The short flashing or Flash can either via another wireless control command or directly by exceeding a certain voltage at the charging Storage medium done.

The transmission of the energy required for wireless operation can in principle take place from two directions. On the one hand, frontally or respectively behind the illumination surface according to the invention corresponding transmitter be arranged. This has the advantage of being in the lighting area distributed bulbs are evenly supplied with energy. In addition, can the transmitter can be placed independently of the lighting surface, so that It stays light and is not connected to electrical energy sources must become. The disadvantage, however, that optionally energy undesirable the environment is radiated. Alternatively, of course, the transmitter Part of the lighting surface itself, for example in a frame for holding the illumination surface. This has the advantage that the transmitter is particularly close to the bulbs, and thus the radiation losses to the Environment are low. For example, a dipole transmitter can be less noticeable Be part of the frame. He is then invisible, if either translucent Are provided surfaces or he is hidden by frame members, the preferably wholly or partly non-metallic, for example of plastic consist.

The energy released to the environment may be shielded be, for example, by fine wire cloth, vapor-deposited or applied conductive layers, which are preferably transparent. A closed one System is obtained when a frame element is provided in the between two transparent conductive layers, for example corresponding ones Tension films, the illumination surface according to the invention is provided, and to Inside the frame the dipole antenna is arranged.

If the electrical consumers are individually addressable, it is possible to selectively activate individual consumers or groups of consumers. This allows, for example, a bus-like supply to all consumers, thereby less tracks are needed. The energy and / or signal flow can of course also done wirelessly. The activation can be done, for example, by digital Transmission of the address and the switching state take place, as for example is known in the light control technology DALI standard. A Addressability according to the invention can also be non-digital: Zum Example, if the individual consumers or groups of electric Consumers are assigned different frequencies. In the simplest case This happens because lighting means are provided which form a resonant circuit having certain resonant frequencies. The activation of the different groups then happens by sending energy with the aforementioned frequencies. This is particularly easy with few components and without the application of data technology at the same time one Information and the operating energy to the appropriate consumers transfer. Preferably, the consumers are addressed in such a way that in particular picture elements or lettering in each case from both sides of the Carrier surface are displayed in the right way, for example, if consumers too Both sides of the support surface are arranged.

In one embodiment, conductors are on the illumination surface or carrier surface provided that are connected to the electrical loads to this To supply operating power and / or signals. In the simplest case These can be sheath-insulated, enamel-insulated or bare thin wires. ever After removal of the viewer from the lighting surface they are doing this due to the thickness / color, etc. not noticed and therefore also considered transparent conductor in the sense of the invention. In the simplest case, these ladder glued to the surface, for example, as a pair of conductors, bus-shaped or as Matrix. In the case of the matrix there are either because of the numerous crossing points insulated conductors or at least in the area of the crossing points insulated conductors to use. Alternatively, the conductors on both sides of the insulating support surface or another insulating layer so that an insulated conductor is not necessary. Wire or cable-like conductors can be easily attached to the Carrier surface, for example a PVC film, glued or welded with this become. The conductors are designed by your resistance so that their unavoidable heating power remains low in relation to the consumers supplied power. Furthermore, there is the possibility on the support surface to print the printed conductors, wherein an electrically conductive paint is used.

If the leaders are transparent, this has the following advantages: In the case of a transparent / translucent lighting or support surface are the conductors virtually invisible and are not perceived as disturbing. In addition, you can therefore invisible, that is, without disturbing the free view, a very large Number of conductors are applied, for example, a large variety of Lamps individually or in groups can control. Especially at So-called RGB controllers can, for example, four lines per diode be required (common mass, red, green, blue). The transparency respectively The translucency of the lighting surface would not be more given when a very large number of bulbs with wires too supply. Of course, transparent conductors according to the invention do not mean that they are perfectly invisible. Transparency is still there, if some slight shading, discoloration in any case or under certain angles / lighting situations is visible. It is essential that This is so small that it is the viewer compared to the overall effect the lighting surface does not immediately catch your eye. In the case of a translucent or even opaque lighting surface, it can be quite a non-insignificant Head on the back of the lighting surface not the viewer catches the eye. However, for example, a matrix-like arrangement of the tracks, as is common, for example, with boards in comparable applications is to create, at least on the front of the invention be provided transparent conductor. This simplifies the layout of the Conductors in a large number of LEDs, as the connection or Intersection points of the tracks are not on a common side of the Illumination or support surface must lie. Transparent ladder in one particularly inexpensive process also printed, sprayed or glued are, for example, a c-axis oriented film of zinc oxide and aluminum as main components, or of Au, SnO3, In2O3, CaO, ZnS and ITO (indium zinc oxide, as disclosed for example in DE 36 39 508 A1). These are usually flexible as well.

The printing or spraying using a stencil or on the Illuminating surface of applied adhesion promoters or plasticizers has the ladder the advantage that arbitrarily complex traces layouts as often without additional effort can be reproduced. Adhesive transparent Conductors, for example of the role, are particularly suitable for flexible production such traces on site and for areas of very large dimensions, the can not be printed with reasonable effort.

In a further embodiment, it is provided that the conductors, in particular the transparent conductor, are stretchable. Examples of such conductors are graphite foils or Polymer inks, Fa Precisia LLC, 731 Fairfield Court, Ann. Arbor, USA-MI 48108. As a result, such illumination surface according to the invention with electric consumers are very extensible, such as For example, films, clamping films, awnings or screen films, for example in an umbrella, additionally as eye-catcher, as street lighting or the Safety of the wearer by better recognizability, can serve. With the two The latter would certainly also have non-stretchable conductors, for example wire and wire the like, but a failure of the connections is due to Fatigue break or overstretching in a gust of wind very likely a repair would be almost impossible. Enable flexible conductors the use on bendable surfaces, for example, folded or rolled up can be used for transport purposes, for example. Also thin wires that rectangular, wavy or sinusoidal are applied to the elastic surface, can act elastically and with appropriate thinness or distribution or distance of the observer also appear transparent.

In a further embodiment it is provided that an area behind a transparent / translucent surface, in particular a flexible surface such as Example, a foil or stretch film is hung. Preferably, the Tension foil thereby by means of circulating piping in an encircling profile clamped, which is the usual edge fastening measures for tensioning foils in the Stretch ceilings or Spannwändebau corresponds.

In a further embodiment, it is provided that the inventive Surface forms a wall or ceiling, or part of such is. For example, walls may be substantially vertical surfaces, which delimit a room from its surroundings, for example an outer wall or walls that are placed inside a room, for example as Room dividers, exhibition stands, displays for advertising or projections, noise barriers, Shelves, counters, decorative objects and the like. The same applies to ceilings, however, a more horizontal orientation above or below the Observer present. In this case, the illumination surface according to the invention forms with electrical consumers either the wall or ceiling or is part of it, as the following example shows: Below a truss-like glass dome can illuminating surfaces of the invention hung with LEDs or a corresponding network become. In doing so, the above effects may be related to, for example, Daylight and darkness are just as well implemented, as if the Glass surface itself would be provided with the bulbs, but decreases the Nachrüstbeziehungsweise Production cost, as no glass plates with bulbs must be provided and no replacement of the same is necessary. The repair effort in case of failure of the bulbs is also much lower, since not the whole glass pane, which is mostly weatherproof in an overall construction is embedded, needs to be replaced.

Further advantages arise when the surface is heat resistant (prevents faster aging or higher yellowing or turbidity by the Heat of the bulbs), self-cleaning (for example, by appropriate Coatings, for example, after the lotus effect, so less cleanings when used outdoors), flame retardant or other Requirements of the authorities, building authorities is designed accordingly. This opens up new fields of application of the lighting surface For example, in public areas, in transport, such as Planes, etc ..

The same applies, of course, when retrofitting a glass facade or Creation of a facade cladding based on the invention Lighting surfaces. This can then, for example, as a large-scale advertising or animated area or even, with appropriate control, as Serve big screen TV. In a further embodiment, the area with Advertising provided, for example, by a partial or total printing of the illuminated area, the novel design of the lighting area for Increased attention of the viewer for the advertising message ensures.

The subdivision of the support surface into a transparent / translucent support, the essentially the stability of the support surface and a transparent / translucent Recording layer for embedding consumers without bearing Function with respect to the support surface itself, allows the selection of the for the appropriate functions (stability and embedding) optimal materials. Embedding involves both only a lateral stop, that is the consumer partially penetrates the receiving layer, as well as the complete embedding the consumer is protected against the environment. The production effort can be further reduced because the carrier separately and optionally can be produced industrially, or on already existing Backing materials can be used. Applying the transparent Recording layer can comparatively easily by lamination, bonding, Brushing, squeezing, spraying and the like happen, especially after the application of the consumer on the carrier. The recording layers can be on one or both sides on the carrier and also the protection of the ladder to Example against damage, scratching, corrosion, especially in the area of Connecting points to consumers.

As a transparent carrier in particular the materials glass, Plexiglas, Makrolon, hard PVC and soft PVC and cast resin into consideration. For the transparent recording layer, for example, paints, stretchable paints or Polymer inks, rubber and comparable elastic flexible acquisition layers, or thin receiving layers of soft PVC can be used. The Recording layer can of course also current conducting, so as a conductor in the sense of Invention be configured and, for example, the entire surface of a common Form mass.

When consumers are accordingly small and operate wirelessly can (for example, SMD LED chip with dipole antenna), it is preferred initially intended for the production of the transparent recording layer Mix the material homogeneously with the reflectants. Only then takes place the application of the recording layer on the carrier, with no additional Work step is ensured that the miniature consumers evenly and with be embedded in the recording layer of different orientation. One Streaks of electrical consumers in the not yet hardened applied Recording layer is also possible, especially for achieving a approximately uniform orientation.

If the recording layer is embedded between two carriers, that is Recording layer less sensitive to moisture, environmental influences, Scratching, aging, hardening, etc ..

If the lighting surface is UV resistant, it can be outdoors be used and age less quickly. It just depends that the parts of the lighting surface that are actually in contact with ultraviolet light come, are designed accordingly.

Further special optical or acoustic effects can be achieved, if conductors are provided in the area, the electrical consumers, especially LEDs, SMD LEDs or sound sources. Are leaders For example, wires or vapor-deposited printed conductive layers. If the transparent lighting surface is flexible, the conductors are also to provide flexible. The production method described above for the Lighting surfaces according to the invention offers the advantage that the electrical conductor in particular on both sides of the transparent support in the transparent recording layer embedded or between them can be brought. The carrier or the transparent one Receiving layer serve as fasteners for the conductor and as Insulator for this, so that inexpensive, insulator wires are used can.

In a particularly advantageous embodiment, the conductors are matrix-like arranged. This means that the conductors intersect without getting electrically attached touch. For example, the conductors are connected by corresponding consumers who arranged the two isolated from each other Electrically connect the conductors. Ladders can be used to Operate the consumer and transmit data, such as in a bus system. This makes it possible with fewer conductors a variety of Consumers individually or in groups to control.

The flexible, light-emitting illumination surface according to the invention is suitable especially for awning or awning cars, as by the lighting means special optical effects can be achieved, the hitherto in this context not yet known. A roofing system with a variety of Awning car is described in EP 0 567 030 and describes an extendable Cover with several parallel blinds at the at least one roller blind in Guide rails is slidably mounted and in the awning curtain at least one roller blind with its free end on the adjacent roller blind of the winding shaft is decoupled attached holder members attached. at such roofing devices may further provide intermediate zones which are not covered by awnings, but a permanent one Roofing, for example in the form of a glass roof, a glass dome and have the like. In a further embodiment it is therefore provided that this permanent roof instead of glass transparent to the invention Illuminating surface has.

In a further embodiment, it is provided that the inventive Illuminating surface can be freely set up or suspended. openable means that the illumination surface is designed such that the user without installation effort can change the position, the illumination surface is designed so that it can be placed anywhere without Risk of falling. The focus must therefore be on the corresponding known rules of physics in a suitable relation to the base area. The lighting surface can be suspended if it is connected to one, several or All edges or corners can be attached, for example, as a room divider or aperture in front of a window. Example of easy attachability in the sense The invention is at Saugnäpfen on smooth surfaces, hook-and-loop fasteners appropriate substrate or glued to the substrate Gegenklettbändern, so with any fasteners, for a temporary Attachment are suitable. All these configurations serve the flexibility of Illuminated area and reduce the retrofit, since they, for example Can be hung by anyone without special assembly skills. In another example, retaining means, for example, bracing rods between the walls, for example, at a window opening, provided in the upper and lower, over the width of the surface extending guide eyelets are introduced and thus span the lighting surface. The bars can, for example, by twisting, and the lighting surface for Example by cutting to length, be changed in their width and thus to different Requirements are adjusted. The 90 ° offset Holding means of course also be installed between floor and ceiling and thus with very little effort to wear the lighting surface as a partition. Similarly, any 3D objects can be created, with the web-like surface around any aligned edges, such as the holding means, rods, etc., is diverted or held to this.

An extremely high flexibility is obtained when the illumination surface according to the invention is cut to length. This means that the lighting surface through to the Example cutting, sawing in their width or height, even if necessary other shape, can be changed without affecting the electrical operability is impaired. This is when wirelessly controlling the bulbs in given in any case. For example, in the case of conductors laid in the area, this goal is achieved then reached when the conductors are arranged like a matrix. At vertical, horizontally or diagonally running cuts, no cut is conceivable, at which the remaining partial surface can no longer shine completely. The ladder Of course, they can also be laid side by side in pairs in the same direction. Cutting off an edge will then result in neither horizontal nor vertical Cut to the inoperability of the remaining part.

In a further embodiment, the illumination surface is designed as a shutter. In this case, the, the lamellae in the vertical direction interconnecting Guide cables or the tension cables guided by the slats as a conductor be formed so that the blinds are initially not of commercial different. Illuminants can then be placed anywhere, for example in or be arranged on the slats and so for a lighting of the room or provide illumination of the slats themselves. It is beyond that advantageous if means for switching on or off of the lamps provided are. This can be done for example by a separate switch, the the cables are de-energized, happen. The drawstrings can of course also like that be guided by the slats that only when tilting the slats against the Pull threads a contact, for example, is made by the clamping action. By appropriate design or insulation of the holes for the tension cables in the Slats can be prevented from being inadvertently, that is in the raised position or not tilted state, a power cut produced becomes.

In further embodiments of the invention, in particular matrix-like Arrangement of the ladder different possibilities to individual or groupwise Control of the bulbs explained, with a better understanding 4 is referenced. Between lines Z1 - Z4 and columns S1 - S4 are each light-emitting diodes L1 - L4 connected to the conductors, so they at Apply power to the corresponding row and column light up. Of course Rows and columns are interchangeable without the teachings of the invention leave.

In a first variant, the rows and columns are arranged Illuminant similar to the Fernsehbildaufbau columns or activated line by line. That means first the first line Z1 with the Power source connected while and in succession or simultaneously if appropriate, the corresponding columns S1-S4, in which bulbs L4, if they belong to the first line, they should light up. After that, the second one Row Z2 connected to the power source and the column-wise control repeated. With appropriate speed of the control results a high frequency for each single lamp L1 - L4, so as a result of the Inertia of the Human Eye the Impression of Permanently Illuminated Points L1 - L4 is created. In addition to special lighting effects, screens are also such realizable. Because of compared to the fluorescent film of a TV screen small afterglow time of light emitting diodes is one of the eye as pleasant picture with the above method but under Circumstances then not satisfactorily producible if 640 columns and 320 Lines are provided. Therefore, in a second variant, it is proposed that The bulbs are such that they have a variety of states on one can take appropriate signal out. A state is through his Brightness and / or color marked. The following example: The Illuminant comprises an LED and a control, for example a integrated circuit. The circuit can also be integrated in the LED, such as This is known for example from self-flashing LED's. All lines and Columns of the matrix are initially supplied permanently with 3-volt, with the Lines negative and the columns positive voltage. The circuit of Illuminant is now such that the permanently applied voltage of 3 volts is sufficient to make the LEDs shine maximum. The integrated In this case, the circuit comprises a memory circuit which is capable of Absence of a signal to maintain the last switched state. If applied to the integrated circuit 5 volts, for example, changes a flip-flop its condition and the lamp goes out or on. This can one row at a time and one column at a time, but specifically, every single illumination be switched on or off by briefly increased Voltage of 5 volts is applied. To avoid several at the same time Bulb of a row or column unintentionally change state suggested that at the corresponding line the negative voltage greater and at the same time increases the positive voltage at the associated column becomes. In the example above, the line is -1 volts and the column +4 volts, so that the integrated circuit with 5 volts briefly applied becomes. On all other bulbs of the same column or row are thus only 4 volts, which is no change in the switching state caused. By successive processing of the rows and columns can thus targeted the state of each individual bulb will be affected, the condition maintained even after elimination of the control or the signal voltage becomes. This results in a flicker-free picture. It can all here too Bulbs of a line can be addressed simultaneously.

Although the above example assumes only an on / off switching, so are still "grayscale or colors" possible. For example The integrated circuit could be voltage dependent depending on the lamp steer brightly and maintain the last controlled brightness. To faulty circuits However, it is important to note that the lowest and lowest highest value of the voltage increase of the columns are smaller than the highest Value of the voltage reduction in the lines.

Example: The lamp is dimmable proportional to voltage increases of 2.1 - 3.1 volts. The voltage reduction in the line is 1.1 volts and the Voltage increase in the columns is therefore 1-2 volts. voltage increase Under no circumstances can and the lowering of tension alone be able to do so Lamp to suspend an increased voltage of more than 2 volts. One unintentional switching is thus prevented.

Of course, even more dependable is the following design: The bulb is dimmable proportional to voltage increases of 11-15 volts. The lowering of voltage in the line is 9 volts and the voltage increase in the columns is therefore 2-7 volts. Voltage increase and voltage reduction alone Under no circumstances are the bulbs of an increased voltage capable of doing so of more than 9 volts. An unintentional switching becomes like that prevented.

In the two aforementioned methods, namely the driving of the normal Light emitting diodes or light emitting diodes with memory circuit is the following Configurations to speed up the process possible: Only the Lines or columns with voltage or control voltages acted upon, in which there are bulbs that light up or to be influenced in their brightness. In the example of FIG. 4 So you can omit the 4th line Z4 and the 2nd column S2, so that in this Example, a 25% faster image structure can be done. Alternatively or In addition, it is also possible to control all columns of a row equally, Thus, in the embodiment in Fig. 4 when driving the line Z2, the Lamps L1 and L2 by simultaneously applying the columns S1 and S3 be brought to flash or to control.

It is a data compression method, with only the Changes to the screen contents are processed. Such a procedure is basically known in the software sector. However, in the prior art compressed before the video or screen signal is generated. The control the screen itself is uncompressed. On the screen itself namely in the prior art always all rows and columns - regardless of one Change or not - driven. New here is that data compression takes place in the screen itself, with the individual pixels themselves their Condition until a change is maintained. Claimed here is also protection for the method described here for driving a screen, the structure a screen and the construction of a pixel or a group of Pixels, so for example a bulb, which indicates a signal, for example the above-described voltage increase and the like, a specific one Brightness and / or color and this maintains after the loss of the signal.

Claimed is also a light emitting diode in a compact housing a Circuit, for example, IC, for carrying out the above method. A Similar circuit is known from the already mentioned flashing LEDs. The above described organic semiconductors are particularly suitable for simple Structure of the illumination surface according to the invention, since for example both Illuminants, as well as controls, circuits for carrying out the image control method, such as Flip-Flop, especially easy on the lighting surface can be applied by means of the commonly used in this field. This is all the more true as this technology is partly transparent / translucent.

Regardless of the function of the area as a monitor or scoreboard, it lends itself basically the possibilities to operate the LEDs in continuous operation, which causes very high currents or the LEDs with very high currents Speed one after the other very light, with the frequency of each single LED must be so high, the one for the human eye Impression of a permanent lighting arises.

Finally, the columns S1 to S4 per light spot L1-L4 can also be multiple times be provided, for example, the individual colors of a RGB LED to be able to control individually. The previously said in terms of driving a Red dot with or without integrated circuit or storage of a condition, analogously fully applies also to colored illuminants, for example, those in a housing a red, green and blue Have light bulbs. To speed up the image construction can also be provided that the screen in a variety of identical, individually is subdivided to be controlled. As a result, any size of light walls can be built up by standard components, depending on the drive, an image pixel one or a plurality of bulbs can be constructed.

The following example shows a particularly advantageous embodiment:

A video signal, for example, VGA signal is busily a variety of Control modules supplied. Each of these control modules, which has a specific Partial area of the entire image represents, according to the invention, the To control bulbs of a partial surface. From the basic video signal, which For example, a 640 x 320 pixel image represents each processed Control module only a partial section, for example lines 1 - 50 and columns 1-50. The adjacent control module processes columns 51-100 in the rows 1 - 50, etc .. Each individual module is thus provided with a control that out an overall picture only processed a picture detail. As the image refresh rate may be low because of the large number of bulbs to be controlled can or during the compression process of the image changes depends, the invention is particularly suitable for displays with still images or temporally / spatially moderately moving images.

An illumination surface according to the invention can also be used in the free surfaces of a Be mounted timbered. In particular, in the embodiment as a film thereby - when using appropriate truss profiles - very large, lightweight and stable structures can be built up, for example, cubes, domes, spheres, etc. Trusses have the advantage that, for example, when using standard struts - the objects created from it are very versatile and In addition, a simple buildability and portability is given. Such objects can be outdoors or indoors, for example at trade shows be constructed. A foldable truss has the advantage that - if necessary after the removal of the free spaces of the framework filling areas the structure can be quickly collapsed or built up, namely, without having assembled a variety of elements according to a blueprint Need to become. Such trusses are also known as grid-carrier systems known.

If before and / or behind the lighting surfaces according to the invention more transparent or reflective films are provided, resulting from Multiple reflections further optical effects. A lying in front of the bulb transparent film may also be in the range of light emission of the illuminant be printed so on the one hand to promote the multiple reflection and on the other hand, as a luminous surface in the direction of the observer diffused light radiate.

Built from lighting surfaces according to the invention or this having walls or ceilings are also sound-absorbing, Mobile, flexible, easily transportable elements can be used, which the Significantly improve the acoustics of a room. For example, in the exhibition area This allows quiet areas for customer discussions or presentations be created. Acoustically advantageous properties are, for example achieved in that the surfaces according to the invention or before these arranged further surfaces slotted, studded, perforated or with others irregular structures are provided which absorb or scatter sound can. It is of course important to ensure that the operability of the Bulbs are not affected by these slots, pimples, holes, etc. are, so they are arranged so that no traces interrupted become. Also, these interruptions should not affect the aesthetics, for example, by an excessive number of edges that the light break. This creates aesthetically sophisticated partial protection walls, which are not recognized by the viewer as such. In principle, the inventive Illuminating surface Component at least one-sided be transparent or translucent chamber systems in which the noise-causing Air vibrations consumed, that is converted into heat, are, such as the silencer. The surfaces of the invention can similar to a computer rack designed to be standardized Form modules that can be inserted into the shelves, trusses and the like, in particular, these may be addressable by hardware or software and / or an electrical contact during insertion are automatically effected can while a mechanical connection is made. Through identical modules or a limited number of different modules, for example in different grid sizes or shapes, can flexibly different Designs are created.

The connection between conductor and light source can also be achieved by simple "Piercing" and possibly catching occur when the contact wire of the Illuminant is designed such that it can pierce the conductor, such as Example of conductors made of fine copper wire and a pointed contact wire, the possibly provided with barb-like roughening and the like.

The area may also be a window, in particular for a means of transport, for example, be an airplane. This may succeed in long-haul flights desired impression that through the usual opening (window) Daylight falls into the interior.

In the field of decoration, especially window decoration (poinsettia, Fairy lights, etc.), the usual mechanical constructions (Fachwerk and lamps) by the mechanically simpler and cheaper in bulk can be replaced producible film according to the invention.

When using the illumination surface according to the invention as a monitor revealed the advantages in comparison to known TVs, especially large-screen TVs, because of the transparency / translucency when not in use, the device as less disturbing or even perceived as a design object / art and also lighter is.

If the lighting surface or module is waterproof or weatherproof is, arise in novel applications in the field or outdoors Underwater area in pools, wells, etc. This may u. A. by the already described encapsulation of the contacts and lamps through the multilayer Construction done.

On both sides or in all directions radiating bulbs can under Circumstances facilitate the production, since not on the orientation of the Lamps must be respected. Also, the lighting surfaces versatile, since they radiate, for example, in two areas at the same time can.

Several individual lighting surfaces, whether as a module, decoration object, Window decoration and the like may be further connected to each other synchronized to be controlled. Thus, for example, at a Facade by means of the windows marquees, patterns or the like and in particular Large-screen projects are generated.

There may also be reflection means in the illumination surface or carrier surface be provided. These have the purpose of the invention to scatter the task reflect or reflect. These include, for example, mirrors, mica platelets, Holograms, printing surfaces, diffuse particles or shiny particles. It It is understood that the distribution of the reflection means in the illumination surface depending on the application and desired effects is very variable. It comes but in particular that on the one hand in daylight the impression of clear view through the transparent lighting surface is ensured. Supporting can also be provided that the reflection means the Let ambient light through or adjust their color, such as this is the case for example with holographic foils. For the night are the - especially from the inside - irradiated particles in sufficient numbers to provide that one for the viewer shining or at least glittering Illuminating surface is created and / or by scattering, reflection or reflection an illumination of the covered or edged area can be achieved can. The efindungsgemäß desired effect can be influenced by the impression of Starry sky with scattered luminous points up to a large, seemingly reach out to illuminating surface. Preferred are the Reflecting means such that they in the transillumination substantially the Take on the hue of the corresponding light, such as holographic Particle. The reflection means can also be particularly easily printed or printed be.

In an advantageous embodiment, the reflection means should act so that they Light from a uniform direction (parallel rays of light or punctiform Light source) in different directions. The thought is there that gives the impression of a mirrored uniform lighting surface should be avoided and the bright spots of light from the reflecting means are formed, then evenly distributed over the illumination surface act if they are only from one direction, such as a spot, be illuminated. A radiation of light can be through both Scattering, reflection or reflection happen. Scattering reflection means usually do not have to be aligned differently, because the scattering Alone for even, that is undirected light distribution ensures.

On the other hand, reflecting surfaces reflect the laws of geometric Optics and therefore must be in different orientation in the transparent Illuminating surface be provided. For example, scattering surfaces are Paper, frosted glass, prints; reflective surfaces are for example polished or smooth surfaces, mirrors; reflective surfaces are, for example, cat's eyes and corresponding reflective films with microscopic particles. The Reflecting means can also be particularly easily printed or printed.

Preference is given to holograms, in particular the particularly inexpensive and thin Foil or embossed holograms. These have low mass about very well predefinable scattering, reflection, specular and diffractive properties. Therefore, as a reflection means a variety of different Holograms or arranged in a plane but in the plane twisted similar holograms be arranged, but the light radiating from a uniform direction in different directions can radiate. This embodiment facilitates the production of a transparent illumination surface according to the invention, since the reflection means not with different inclination, that is alignment on or in the transparent lighting surface must be attached. That's weird Embedding requires a higher production cost. The radiating in different directions is rather a feature of holograms.

When using a transparent receiving layer for embedding the reflecting means without a supporting function is preferred, first for the Production of the transparent receiving layer certain material with the To mix reflectants homogeneously. Only then is the application of the transparent receiving layer on the support, with no additional Working step is ensured that the reflection means evenly and with embedded in different orientation in the transparent recording layer become. A trickle of particles in the not yet hardened applied Recording layer is also possible, especially for achieving a approximately uniform orientation. If the particles do not come with a recording layer is a better reflection and more beautiful color and color Diffraction effects and the like possible.

If the transparent recording layer with the reflection means on both sides of transparent carrier is applied, a higher luminance can be achieved become. In addition, further optical effects can be achieved if by the Transparent carriers through another considered reflection means have optical effect, as arranged in front of the transparent support Reflection means. Such an effect can be achieved, for example, if the transparent carrier is colored or otherwise like light-changing effect. The Illuminating surface also diffuse or such with the reflection means is provided that they have the function of a screen, for example, for up or Rear projection of static, changing or moving images, met.

Further advantages will become apparent from the following description and the appended hereto Drawings. Likewise, the above and beyond executed features according to the invention each individually or in any Combinations are used together. The mentioned embodiments are not exhaustive and have an exemplary character.

1 shows a surface in a first embodiment,

Fig. 2 shows the surface of Fig. 1 in section in the side view and

Fig. 3 is a surface in a second embodiment.

Fig. 1 shows a lighting surface 1 according to the invention, mounted in a Frame system 40. The frame system 40 is constructed like a truss and may in some or all of the free areas with the illumination surface according to the invention 1 equipped. The lighting area 1, here a transparent one Foil made of PVC as a support surface 2, which in this application also be stiff can, is at its four vertices via connecting means 41, for example one thin wire or a spring held in the frame 40 and simultaneously forms the Support surface for the bulbs. To form a wire matrix are thin uninsulated wires glued to the support surface 2. The horizontal wires 20 are glued to the front of the support surface 2 and are laterally in the Frame 40 and hidden from there to a power connection, not shown guided. The same applies to the vertically extending wires 21, but on the Back of the support surface 2 are provided and thus against the horizontal Wires 20 are insulated. The bulbs, for example, commercially available white light LEDs 22 are at the crossing points between the conductors 20 and 21 electrically connected to these. If a PVC film as a support surface 2 for the Head 20, 21 is used, the electrical connection, for example, by soldering respectively. This can be done without damaging the foil, for example, with very high Power done, because thus the energy almost exclusively in the solder joint is introduced. Also, this can only be loose in the area of the connection of the conductors abut the film and thus have a distance to this during soldering. In this case, at least one pole of the light-emitting diode 22 must pierce the carrier surface 2. In this case, the prevailing in the hole of the PVC film holding forces to do so used to make an electrical contact only by pressing manufacture. As a result, materials can be used in a Contacting for example by welding or soldering damage would.

Fig. 2 shows a sketch of the invention in a frame 40 clamped Carrier surface 2 in section, dispense with the representation of the conductors 20, 21 has been. The support surface 2 with the LEDs 22 is inside the frame 40th held. In the section of the profile 40 it can be seen that in the profile Recess 43 for concealing and guiding the conductors 20, 21, not shown is provided. The room or an extra space created for it Frame can also be used for controls, components, circuit boards, etc. Be that by themselves in the immediate vicinity of the light source to be controlled are located, resulting in only short conductor paths to the support surface 2. Thereby, that these components are hidden in the frame, they are invisible and affect not the overall aesthetic picture. In particular, components can be used translucent or transparent surfaces, also by - at least for one of front viewers - be hidden because they are perpendicular to the surface of the Show away the frame. Of course, this room can also be used for wireless stations Supply the appropriately designed light source 22 serve. Such a Transmitter can be for example a dipole. It can also be seen that On both sides of the support surface 2 more translucent or transparent films 51, 52nd are arranged in corresponding recesses 42 of the frame are anchored. The films 51 and 52 may be in particular tensioning films, the at the edge have a piping, not shown, the anchor-like behind engages a web, also not shown in the recess 42. The whole Arrangement may serve as a prefabricated module for insertion into the frame 40 be formed, which the lighting means, control and connection means for the electrical or data connection holds.

With appropriate design, that is essentially airtight Seal the support surface 2, the Konnektierung the bulbs 22 with the ladders 20, 21 particularly effective against corrosion, pollution, Short circuits and the like are protected. In individual cases it can even Be sufficient that a connection without welding, soldering and just by bringing into contact, for example, against each other pressing, pressing, etc. takes place.

Fig. 3 illustrates a further embodiment of the support surface 2 of FIG. 2, wherein in the transparent layers 11a, 11b electrical conductors 20, 21 are embedded, the are isolated by the carrier 10 from each other. On top of the carrier 10 the conductors 21 are arranged parallel to each other and perpendicular to the corresponding conductors 20 on the underside of the carrier 10. The ladder form thus a matrix that is punctually by appropriate consumers, here one Subminiature LED (SMD LED) 22a, 22b, are connected. By appropriate Contacts 23, it is possible, for example, the LED 22a later at the intended location the conductor 21, 20 to connect, for example by piercing the transparent layers and the strand-like formed Ladder. It is of course also possible to connect before the complete Embedding into the transparent layers 11a, respectively Apply a transparent cover layer above the LEDs. Corresponding This results in the completely or partially embedded variants with light emitting diodes 22b and 22c, respectively.

It has been described above that the illumination surface 1 according to the invention can also be configured as a 3D object, for example as a cube or curved surface. A special effect is also achieved by a Variety of lighting surfaces 1 arranged in different planes become. This can be done, for example, by having many lighting surfaces 1 are stacked with or without spaces. In the case of the individual or groupwise control of the bulbs can be 3D-like Represent objects or motion effects. For example, a Point of light move in three-dimensional space or show its trace become. Lettering, motifs and patterns can be rotated in the room. The described 3D technology is particularly inexpensive, since a variety identical or similar modules can be used. That before described stacking of the illumination surfaces 1 is merely exemplary; much more is of the invention, any arrangement of the surfaces in space feasible, for example, a rectangular arrangement and / or an arrangement in which the illumination surfaces 1 penetrate, for example with crossing lines. Such a "non-stacked" arrangement requires fewer surfaces and allows limited three-dimensional effects.

As a further embodiment or independent invention, it is proposed transparent conductors, for example of the materials already mentioned, For example, ITO to apply a transparent support around to it To pass electricity to the consumers. Such transparent materials are For example, glass rods, glass profiles, nylon ropes, fiberglass etc .. This preserves a substantially transparent conductor, because of its all-around coating with a conductive material a comparatively small Current resistance forms and moreover as invisible respectively inconspicuous support for objects, such as electrical consumers serve can. The conductivity can then be increased if the cross-sectional area of the transparent carrier is increased, for example, by roughening, gearing and the same. Of course, such transparent conductors can also, if they are electrically connected to electrical loads, the inventive Illuminating surface 1 form, that is, the lighting surface 1 consists only of these conductors and the consumers attached thereto, in particular bulbs. Furthermore, it is proposed to couple light into these conductors, so that a luminous conductor is feasible. Known are only light guides that are not power conduct. This allows novel applications, such as Loudspeaker cable or light guide, with individual luminous points (LED), the seemingly shine without power itself out of itself.

In a further embodiment of the invention it is provided that the inventive Lighting surface 1 in walls, floors, ceilings and the like are incorporated. For example, they may be embedded in a soil, in be plastered on a wall or attached to a wall and then be flocked. Basically, the following possibilities arise: The medium with which the illumination surface 1 according to the invention is covered, is transparent or transparent. Then there is no exposure or working out of Illuminant required. If the medium, such as the plaster, on the other hand only is little transparent, the following possibilities arise: After brushing The bulbs, such as LEDs, individually worked out and thus exposed or the bulbs protrude from the surface, so they by peeling off the applied layer of the medium, for example the Plaster, can be exposed.

In a further embodiment, it is provided that the control of the lighting means depending on the ambient temperature. The bulbs can So for example, yourself capture the temperature and their color accordingly change (for example, the bulbs floating in a liquid) or change their color depending on a central thermosensor. For example, swimming pools, aquariums, basins depending on the Temperature are brought into a corresponding color effect.

The inventions enumerated possibilities for the formation of monitors or comparable information display devices or systems for transmission visual stimuli are suitable because of the described embodiments (flatness, low voltages, water resistance) especially for underwater television. Also, such systems as a guide, information, and entertainment in Fun pools, underwater adventure landscapes, diving parks, waters etc. be used.

When using the illumination surface 1 according to the invention as a monitor and the like basically offers the possibility that each of the lighting surfaces 1 itself forms the display or display of a variety of mosaic-like composite lighting surfaces 1 exists, each for represent only a part of the screen content. If the assignment of the Screen section to the individual lighting surfaces 1 variable, For example, only software technology, takes place, there is the possibility of flexible use of the individual elements, so that the screen surface through Adding and switching additional elements is particularly easy to enlarge can. Once a set of elements has been acquired, it can either be a large one Number of small screens, some large screens or a very large one Make a screen.

Furthermore, the lighting surface 1 according to the invention is proposed and the effects that can be achieved with conventional advertising or neon signs to combine. Conventional neon signs are for example curved neon lights, backlit signs, etc., also in the usual way and can be animated or moved. Such animations are for example the sequential lighting of different fluorescent tubes, the flashing and the method of a neon sign or an object. This will achieve that, for example, a consistent advertising message is particularly inexpensive, that is conventional, can be implemented and only for the invention achievable special lighting effects the illumination surface according to the invention 1 is needed. When using, for example, the relative low-light-emitting diodes, which are poor in daylight or sunlight are visible, they are then only at decreasing brightness of Environment switched on. By contrast, the conventional unfolds during the day Neon sign their effect.

Finally, the lighting surface 1 according to the invention can be advantageous for the Daylight simulation can be used in rooms. Daylight simulation affects There is a positive impact on human performance, where spaces bad with Daylight is supplied or people are against the natural night / day rhythm behavior (shift work). The illumination surface according to the invention 1 offers advantages here, as they are very simple because of their small depth can be used over a large area. This effect is beneficial since it is human It is used to light falling through large windows into the room. Therefore, will large-scale light felt particularly natural.
