Description

The invention relates to a luminaire according to the preamble of claim 1.

A lamp of this kind belongs to a known lighting principle and is eg in the DE 299 06 884 U described. Essential parts of such a luminaire arrangement or luminaire are a base body with laterally opposed base body parts, which are connected to frontal base body parts and / or bridge-like base body parts and thereby form a trough-like base body, and connecting elements for a preferably formed by a lamp light source in which it is can act to the mechanical support of the light source and the electrical connection of the light source to an electrical supply network components.

A luminaire arrangement or a luminaire of this type can have a considerable side length. This is e.g. in elongated lights with a tubular or rod-shaped light source of the case. But there are also lights with large longitudinal and transverse side dimensions. In this case, a plurality of such lights in successive positions form a so-called light band, which is used for lighting in particular of long or large spaces, such as. Office or sales rooms is used. The larger the side dimension of a prescribed luminaire arrangement or luminaire, the more stable education is required.

From the document US 4,338,653 is a versatile lamp is known in which a base body and edge rails are available. The luminaire can be mounted either in corners or on flat surfaces.

The invention has for its object to improve a lighting arrangement or lamp according to the preamble of claim 1 in terms of their use and / or stability.

This object is solved by the features of claim 1. Advantageous developments of the invention are described in the subclaims.

In the luminaire or luminaire arrangement according to the invention, the base body is covered and / or stabilized by at least two laterally opposite edge rails, which can be connected to the base body or parts thereof and are arranged on the outside with respect to the base body or parts thereof. This makes it possible to dress the base body at least laterally with the edge rails, so that the lamp assembly or light can be optionally designed as recessed without edge rails or as surface-mounted luminaire with edge rails. The Edge rails not only provide an advantageous cladding for the base body, but they also stabilize it, if a stabilization of the base body is desired.

The embodiment according to the invention with two mutually opposite lateral edge rails is suitable for lamp sections of a so-called. Luminaire row, in which only the opposite side surfaces of the lamp sections are visible. However, the embodiment according to the invention is also suitable for individual luminaires, when the opposing edge rails are also arranged on the front side of the base body and preferably form a frame.

Conveniently, the edge rails extend over the entire height of the base body, so that from the outside substantially only the edge rails are visible, which can be formed in a simple manner so that they have a pleasant appearance.

The connection of the edge rails with the base body or the parts thereof can be easily and quickly and handling-friendly, since the grooves in the edge rails allow a connection at optional points by means of connecting elements in the grooves, e.g. Screws whose heads border in the undercut grooves or the threaded bolts are screwed into the grooves in the sense of Schraubnuten. The edge rails increase the moment of resistance of the base body or at least its side walls, so that even with long side dimensions of the lamp sections or the lamp a stable and reliable connection is achieved.

The edge rails are preferably profiles, which ensures cost-effective production of the edge rails including their grooves.

In a preferred embodiment, the grooves are arranged in an obliquely extending towards the room side of the lamp connecting web, wherein tongues are cut out and bent out of the side walls of the base body, which are securely fastened by means enclosing in the grooves fasteners.

In the case where the edge rails form a frame, it is advantageous to provide corner angles in the corners of the frame which are connected to profile legs extending between the corner angles. A connection of the edge rails directly in the corners is not required, since the corner angles provide a stable attachment outside the corners.

Further development features of the invention are described in the subclaims, and they lead to small and inexpensive to manufacture and mountable or demountable embodiments, which are advantageously in the tight space of a lamp, e.g. a surface-mounted luminaire or a ceiling light, can be integrated and guarantee a small construction despite stabilization.

The main parts of the designated in their entirety by 1 light are a base support 2 with a base body 3, here in the form of a frame or an upside down tub on which or on the opposite side walls 3a holding arms 4 outwardly and pivoted and preferably height adjustable (not shown) are stored, one or more, z. B. two, arranged in the interior of the base body 3 lamps 5, here gas discharge tubes, which are detachably mounted by means of jacks 6 on the base body 3, a reflector 7 for the at least one lamp 5, a flat or plate-shaped cover plate 8 in the present embodiment with a broadside radiating surface 8a, which is sized larger than a radiating aperture 9 in the base body 3 of the lamp 1 and thus not only the radiating aperture 9, but also edge strip 11 at least to each other covering opposite edges of the base body 3. In the present embodiment, the edge strips 11 by the free edges of the side walls 3a laterally projecting edge legs 11a. formed, the free edges of their stabilization to the cover 8 facing away from side can be angled away by edge leg 11b. As a result, an edge region 11c of the base body 9 is formed. It is the purpose of the edge strips 11, a mounting gap in a mounting hole of a ceiling 13, in which the lamp 1 is installed as a recessed light cover, the edge strips 11 overlap the edge of the mounting hole and rest against the underside of the ceiling 13. The cover 8 is held by at least one releasable holding device 14 to be described on the base body 3, preferably on the edge strip eleventh

In the functional operation of the luminaire 1 equipped with conventional equipment, the light generated by the lamp or lamps 5 is emitted through the emission opening 9 and on the emission surface 8a into the space to be illuminated. To illustrate this emission light, a resulting main light beam is shown as an arrow and designated 15.

The lamp 1 or the shape of its emission opening 9 or its cover 8 can be square, z. B. rectangular, or square. In the present embodiment, the shape of the lamp 1 or its emission opening 9 is rectangular and oblong, wherein the side walls 3a and the edge strips 11 are located on the longitudinal sides. At the narrower end faces are also opposite side walls 3b present, which are connected to the side walls 3a and form the aforementioned trough. In such a case, the lamp 1 is a single luminaire, wherein the edge strips 11 are also arranged on the other two sides, here the narrower transverse sides, ie circumferentially.

At the in Fig. 1 However, it may also be an arrangement consisting of a plurality of successively arranged lights 1 line of lights, at the ends of each a light 1 is arranged with an end, transversely extending side wall 3b, while arranged between the end-side lights 1 lights trough-shaped base body 3 or pans without transverse side walls 3b have. In such an embodiment, the longitudinally arranged along the light line cover plates 8 can be associated with Butt joints (not shown) abut each other. Also, the respective base support 2 and reflectors 7 may abut each other at the respective butt joint. The installation opening is taking into account the number of successively arranged lights 1 form correspondingly long. Such a configuration is particularly suitable for tubular lamps 5, in which the lights 1 have an elongated design.

The reflector or reflectors 7 consist in a conventional manner of two opposing and - seen in the longitudinal direction of the lamp 1 - concave rounded reflection walls or a tunnel-shaped reflection wall 16, in the present embodiment, for. B. a so-called double or multiple light, double or multiple exists. The respective reflector 7 or a common reflector 7 for several lamps 7 is on the base body 3, preferably releasably attached, as is customary, for. B. by means of Verrastungsvorrichtungen (not shown), which allow a handling friendly and quick installation or removal through the emission opening 9 therethrough.

Between the cover 8 and the at least one lamp 5, an inner plate-shaped cover plate 17 is arranged and not shown by fastening means, for. B. support or at least one latching device, be releasably held. The cover 17 is made of translucent material 1 and is used to influence the light. It may be clear or partially translucent or made of opal material, so that it emits a diffused light image, whereby zones of different light intensity of at least one light source are made uniform and a more uniform and low-contrast light image is delivered to the cover 8. The light emitted by the cover 8 light image is therefore uniformed accordingly, even if the existing translucent material cover 8 is made of clear material. The emitted from the radiating 8 image is even more even if the cover 8 consists of teillichtdurchlässigem or opal material. The cover plate 8 can be smooth on its emission surface 8a or have a structure 8b, in particular a microstructure, whereby the light image on the emission surface 8a becomes more brilliant. The radiating surface 8a may, for. B. rough or dull. In addition, the flat or plate-shaped cover 8 receives the ability of a light pipe, so that the light not only transversely penetrates the cover 8, but in the cover 8th also transversely to the main emission 15 in the edge strips 11 overlapping edge regions is passed, so that the light in these areas on the radiating surface 8a radiates. As a result, these present in the prior art dark edge regions of the lamp 1 are avoided or at least reduced.

Alternatively, the cover 8 may also be made of opal white material, preferably perldiffusor, in particular of PMMA.

In addition, the cover 8 can also serve to illuminate the surrounding peripheral area, -. B. in a ceiling light surrounding the ceiling area. This is made possible by the fact that the cover 8 also has a radiating surface 8c on its circumference or its peripheral surface, radiates at the light and contributes to brightening the environment of the cover 8 and the lamp 1. The regions covering the edge strips 11 and the light rays emitted in the peripheral region are designated 15a, 15b.

The suitability of the cover 8, the light to conduct transversely to the main emission 15 increases with increasing thickness of the cover 8 to. In experiments it has been determined that a ratio of the thickness a of the cover 8 to the width b of the covered edge or the edge strip 11 is about 1: 3 to 1: 1 behaves, preferably about 1: 2. At a width b of about 12 mm, this results in a thickness a of the cover 8 of about 4 to 12 mm, in particular about 6 mm.

Preferably, the cover 8 is made of clear plastic material, in particular clear PMMA, wherein it has microprisms at least at its emission surface 8a. These microprisms are optically optimized and by known steep slopes of z. As pyramids or webs formed, the inclined surfaces include an obtuse angle W of preferably about 116.5 °. This ensures that the luminaire is blended in accordance with the standard (1000 cd / m ² at shallow angles greater than 65 ° with respect to the central axis or emission direction 15). Underneath, the luminaire should emit approx. 4000 cd / m ² . The tips of the pyramids are spaced apart. Such a cover 8 can, for. B. to about 8 mm thick. It looks especially in crystal clear design due to their thickness a high quality.

The microstructure may have different shapes. It is also possible to form the microstructure by triangular profile prisms, which are formed by triangular cross-section elongated grooves, as it is Fig. 2 shows. The distance c of adjacent peaks or bumps may be about 1 mm, wherein the included by the oblique surfaces of the triangular shape angle W may be about 116, 5 °.

In the case of a structured emission surface 8a, reflected light rays 15c emerge at the lateral emission surfaces 8c which are directed transversely to the emission direction 15 or obliquely to the emission direction 15. This is for illuminating the environment particularly favorable, especially in recessed or surface-mounted luminaires. The microprism structure after Fig. 2 is suitable for elongated lamps 1, in particular, if the profile of the triangular structure in the longitudinal direction of the lamp runs, as it Fig. 2 shows. Here, the environments of the lamp 1 are illuminated, which are located on the long longitudinal sides and are particularly in need of illumination.

Below, advantageous embodiments for a releasable holding device 14 are described, which is preferably a quick-release connection, in particular in the form of a magnetic holding device or a latching device.

Fig. 3 shows a magnetically effective holding device 14 with a plurality of distributed circumferentially arranged on the permanent magnet 14a, which are each embedded and secured in the upper side open recesses 14b of the cover 8, z. B. by gluing. In this embodiment, it requires a training of the base body 3 and the edge strips 11 or corresponding, preferably rail-shaped, supporting parts made of steel in order to ensure the magnetic function.

The permanent magnet 14 a can according to Fig. 5 be formed by a thin magnetic strip which is attached to the top of the cover 8, z. B. by gluing. These can each be a magnetic strip section or a magnetic strip extending over the entire longitudinal dimension of the respective edge, as it is Fig. 6 shows.

In the embodiment according to Fig. 7 the holding device 14 is formed by a latching device with at least one Verrastungsnase 14c, which engages in the latched position a latching edge 14d. In the embodiment according to Fig. 7 the Verrastungsnase 14c and the Verrastungskante 14d are each formed on an additional component 14e, 14f, of which one component is recessed in the cover 8 and the other component 14c is attached to the edge strip 11, preferably a mounting hole 14g in the edge strip 11 and bordered is axially secured therein. In the present embodiment, the Verrastungskante 14 d is formed by an undercut opening edge of a socket 14 h, which is inserted in an upper-side recess of the cover 8 and is attached, z. B. by gluing. The Verrastungsnase 14 c may be formed on a mandrel which is attached to the edge strip 11, z. B. used in the mounting hole 14 g and locked z. B. is latched by means of the hole edges cross flange. The mandrel and / or the bush can be made of elastically yielding material z. B. plastic, whereby the elastic compliance and locking is guaranteed. Preferably, the mandrel is locked in the mounting hole 14g. The mandrel and the bushing 14h or corresponding components are preferably made of translucent material or the material of the cover 8 in order to avoid impairment of the most uniform possible light image.

In particular Fig. 4 shows, the holding device 14 may be arranged in the corner region of the cover 8. In the case of oblong luminaires 1, it is advantageous on account of the existing length to distribute one or more holding devices 14 additionally distributed in the region of the respective longitudinal edge on the longitudinal edge, which is indicated by dashed lines.

In the above-described holding devices 14 in the form of quick-release connections, it is advantageous to provide an additional retaining device for the cover 8, which at the same time forms a suspension device (not shown), the cover 8 in a suspended and thus a distance from the base body 3 having position on the base body 3 stops. The retaining fuse can be formed by a preferably centrally arranged or two straps that at one edge of the lamp 1, in particular at a longitudinal edge, at a distance from each other with the lamp 1, z. B. with the associated wall 3a of the base body 3, and the cover 8 are connected. In this embodiment, the cover 8 is in the suspended state under the associated side edge of the lamp 1. This is for access to the interior of the lamp 1, z. B. to replace the at least one lamp 5, for reasons of space advantageous.

In one embodiment of the microprism structure in the form of a cross-section, z. B. triangular, webs and / or furrows, the cover 8 may be formed by two over or stacked cover plates (not shown), the microstructure is rotated by 90 ° to each other. In such an embodiment, the light distribution is improved, in particular in the region of the edges of the lower cover 8, which extend transversely to the profile direction of this micro-prism structure. This embodiment is particularly suitable for single luminaires, in which the lateral radiation 15b, 15c is desired on the entire circumference. In such an embodiment, holding devices 14 may also be provided with a suspension device between the two cover plates 8 provided. It can be provided for both cover plates 8, a common suspension device in the above sense at a common edge.

The embodiment according to the invention is also suitable for a so-called light field 21 Fig. 8 in which a plurality of lights 1 are arranged in cascade fashion in one or more rows running side by side or in a crosswise manner. These can be recessed luminaires or even surface-mounted luminaires.

In a light field 21, the edge strips 11 may be formed by mounting rails 22 which are also parts of a base body and are arranged next to a dividing joint 23 of the light field 21 ( Fig. 9 ). In such a light field 21, the support rails 22 may be part of a supporting frame, not shown. The support frame or the support rails 22 may, for. B. be attached to a ceiling or z. B. from a raw ceiling, not shown, for. B. by means of suspension cables suspended.

Fig. 9 shows a support rail 22 in angled or U-shape, with a vertical support leg 22a and a horizontal support leg 22b, which forms the edge strip 11.

The arrangement according to Fig. 9 This is also the case when several recessed luminaires with base bodies 3 are arranged side by side to form the light field 21. To clarify this, the corresponding reference numbers of the recessed luminaire are also inscribed in these figures. This also applies to Fig. 10 ,

In the context of the invention, it is also possible that a cover 8, z. B. due to predetermined dimensions, the respective edge strips 11 only partially covers.

Fig. 10 shows on the one hand the detail X for a surface-mounted luminaire with a base body 3, from the side wall 3a of the edge strip 11 is not outside, but extends inwardly, the side wall 3a with the circumference or associated edge of the cover 8 can be vertically aligned.

On the other hand, in order to form a light field 21, a plurality of such surface-mounted lights can be arranged next to one another in one or more rows running in a crosswise manner, as is the case Fig. 8 clarified.

In a light field 21, it is advantageous to the division joints 23 a small distance d of z. B. about 1 mm, so that clamps are avoided, the difference in dimension of the cover 8 or lights 1 off Temperature fluctuations result. In this configuration or arrangement, the division joints 23 are illuminated by the light emitted at the narrow side surfaces 8c. As a result, predetermined by the division joints dark areas that appear relatively wide due to the relatively small thickness of the cover 8, avoided or reduced.

The dimensions of the cover plates 8 in the plate extension (length, width) preferably correspond to the dimensions of commercially available ceiling modules, namely preferably 600 mm and / or 625 mm.

The embodiments according to Fig. 11 and the following show a lamp 1, which can be formed either as a recessed luminaire or as a surface-mounted luminaire. This lamp 1 can be designed both as a recessed luminaire and as a surface-mounted luminaire with the exception of particular differences according to the above-described embodiments, so that in order to avoid repetition on the description of the above-described embodiments reference can be made. Identical or comparable parts are provided with the same reference numerals. Significant differences exist with respect to a different embodiment of the base body 3 and / or the holding devices 14 for the cover 8 and / or the cover 8 itself or an additional light influencing agent inside of the cover 8. The cover 8 can be clear or translucent (opal) clear and be smooth on their radiating surface or have the structures 8b described above.

A first difference of the base body 3 is that between the edge portion 11c and the inside of the cover 8, a clearance 31 is arranged, which extends up to a arranged on the edge of the cover 8 conditioning part 32, which is part of the support body 3. The clearance 31 is preferably convergent to the edge. In the embodiment, it is bounded by the inside of the cover 8 and its facing and preferably flat outer surface of an edge leg 11a. The boundary surfaces include an acute angle W1 of about 15 ° to 30 °, preferably about 23 °. As in the previously described embodiment, the edge limb 11a and the preferably also present edge limb 11b may be integrally connected to a side wall limb 3a1 forming the associated side wall 3a, e.g. have turned away from her.

Due to the presence of the two mutually laterally opposite or on the entire circumference existing free spaces 31 which emitted from the light source or lamp 5 or reflected from the opposite reflection wall 16 Light directly penetrate substantially to the edge of the cover 8 in this, whereby the external and / or lateral radiation in the area of the auxiliary light beams 15 a and 15 b is improved or enhanced. As a result, light is radiated increasingly in the region of the edge of the cover 8 and thereby illuminates the environment increasingly, whereby the contrast of the lamp 1 and cover 8 to the environment and the central region of the cover 8 is reduced.

Another difference is that at least the opposing side walls 3a, preferably also the end walls 3b of the base body 3, are covered and / or stabilized by a frame 33 arranged on the outside, to which the respective walls 3a, 3b are fastened by a releasable fastening device 34 are. In the exemplary embodiment, the frame 33 extends over the entire height h of the base body 3, wherein the frame 33 may slightly project beyond the contact part 32 and thereby form an enclosure for the cover 8, taking into account a mounting game. The Überragungsmaß e is smaller than the thickness of the cover plate 8, preferably less than half the thickness.

The fastening device 34 has a web 35 which extends in the circumferential direction of the base body 3, and either a circumferentially extending row of holes or a screw 36 in or in the cap screws 36a for direct or indirect attachment of the peripheral walls of the base body 3 at the web 35 by corresponding holes in the side or peripheral walls 3a, 3b can be screwed. In the embodiment, the web 35 extends to the base inner body 3c obliquely downwardly and inwardly, being cut on the opposite wall 3a, tongues 37 in such a position U-shaped out of the wall and bent that they are on the front side of the web 35 abut. By a in the tongues 37 each arranged hole 38, a screw 36a can be inserted and screwed, with her head can rest on the inside of the tongue 37.

The width j of the screw 36 is dimensioned slightly smaller than the outer diameter of the thread of the associated screw 36 a. As a result, the thread of the screwed into the screw 36 screw either by virtue of clamping action of the elastically spread, the screw channel 36 bounding fork walls 35a non-positively and / or due to a shaping or cutting into the groove walls or fork walls 35a positively held so that the respective screw the associated can apply axial clamping force. A particularly stable attachment is achieved if in the groove or fork walls 35a longitudinal grooves 35b are arranged, whose cross-sectional shape is the same or similar to the cross-sectional shape of the thread grooves of the screw 36a is formed.

In the exemplary embodiment, the frame 33 has on its side facing the space to be illuminated R S1 with respect to its width f outwardly tapered and outside preferably final edge web 41 which surrounds the edge legs 11b and preferably partially also the cover 8 in the embodiment. As a result, a recess 42 for the cover 8 or the edge region 11c is created.

The frame 33 may have a side S2 facing away from its cover 8 and may have an edge web 43, which tapers inwardly with respect to the width f, and which has an outer side. Step recess 45 is formed, which is bounded laterally by the outer surface of the edge web 43 and the space R is limited by a preferably parallel to the cover plate 8 extending step surface 45 a. The frame 33 thus consists of a frame base body 46, in the width f, from which on the space R facing and facing away side S1, S2 tapered edge webs 41, 43 protrude, of which the plant side S2 facing edge web 43 to the inside and the Investment side S2 facing away from the edge web 41 is offset to the outside. In the embodiment, the web 35 extends from the step surface 45 a having step wall 47 of the frame base body 46. As in particular from Fig. 14 can be seen, the frame 33 has a projecting from the edge web 41 inwardly and the depth of the recess 42 delimiting boundary web 48, which projects beyond the width g of the edge web 41 and thereby form a bottom wall portion for the recess 42.

The frame 33 preferably consists of lateral and frontal frame parts, which may be connected to one another in the corner regions of the frame 33 and thereby e.g. may be formed miter or at a distance i in front of the corners of the frame 33 and connected by corner angle 49, by means of which the frame shape is completed. The straight-extending frame parts 33a are preferably formed by profile pieces, of which the lateral and end profile pieces can have the same or a different length. The corner angle 49 may be formed by corresponding profile pieces which are firmly connected to each other in the corners. The legs 3a1, 3b1 form a base inner body 3c and the frame 33 a base outer body 3d.

The profile pieces P can be produced quickly and inexpensively by pultrusion or extrusion. This also applies to the profile sections of the corner angle 49. However, these parts can also be shaped pieces, which by injection molding are made. The frame 33 or its parts can be made of metal, for example aluminum, or plastic.

The frame members 33a are connected to the adjacent corner angles 49 by connectors 51, each having one or more, in the embodiment two, adapters 52 which cooperate with portions of the preferably profiled frame members 33a so that they form-fitting an aligned arrangement of two ensure the respective butt joint 53 opposing frame parts 33a and profile sections. In the exemplary embodiment, the profile sections P1, P2 have one or two preferably facing the installation side S2 and facing portion of the profile preferably in cross-section T-shaped longitudinal grooves 53a, 53b, wherein the cross-sectional shape of the existing in the same number of adapters 52 and longitudinal grooves 53a, 53b so matched to each other, eg have the same shape that the profile sections P1, P2 are plugged onto the adapters 52 with little play. The two existing adapters 52 are connected by a cross-connecting web 54 preferably integral with each other. The cross connecting web 54 protrudes at least in the region of the longitudinal grooves 53a, 53b between the opposite ends of the profile sections P1, P2. In order to be able to conceal the gap or gap between them from the outside, the transverse connecting web 54 extends over the entire height dimension of the profile, with the fitting piece or pieces 52 and the transverse connecting web 54 forming the plug connector 51.
