Description

The invention relates to a lamp, in particular with LEDs as the light source.

Such lights are known per se. They consist essentially of an operating device and lighting means, which are controlled by means of this operating device and thus operated. These lights are usually installed as a unit.

The housing of such lights are essentially formed in two parts and usually consist of two housing halves. In the housing halves, the operating device and the lamps are housed together. Ie. The housing halves form a single receiving space for all components of the lamp inside.

This has the disadvantage that in case of a defect, for example, the operating device all components of the lamp must be removed from the receiving space and only then can be replaced. This problem arises in particular with so-called emergency lights, such as illuminated emergency exit signs, which continue to be battery-powered in the event of a power failure. The batteries normally used for this purpose must be replaced from time to time, as they only have a limited lifespan. Therefore, it is laborious for fitters, just to replace the batteries constantly have to take apart the whole lamp.

Another disadvantage is that due to the single receiving space, the lights are relatively high-building. This means that the lamps stand out aesthetically unfavorably very far from the wall or ceiling of a room. The only solution is to install flush-mounted, which, however, works only insofar as the housing halves are usually attached to each other via visually unfavorable brackets. Because of the brackets, the enclosure still has to protrude out of the wall or ceiling so that the brackets are accessible. There is thus a housing half and a part of the other housing half. Otherwise, the luminaire components would no longer be accessible inside.

The object of the invention is therefore to meet the disadvantages and in particular to provide a luminaire in which facilitates the assembly and access to its internal components is simplified.

This object is solved by the subject matter of the independent claims. Advantageous developments are specified in the subclaims.

According to the invention, a luminaire is provided which has a luminous section and an operating section. The lighting section is provided with at least one light source and a light housing enclosing this. Ie. the luminaire housing houses the light source (s). The operating section in turn is provided with an operating device and this enclosing operating housing, so now einhaust the operating device. The luminaire housing and the operating housing are arranged relative to one another in such a way that both housings enclose the luminous section and the operating device at least in a moisture-tight manner with respect to the luminaire to the outside. Ie. the bulbs and the operating device of the luminaire are spatially separated from each other and thus arranged differently accessible anordbar. In particular, the luminaire housing can be optimized in terms of its dimensions to the bulbs out, whereas the operating housing can be optimized for the operating device.

Preferably, there is at least one open passage between the two housings through which the operating device is electrically coupled to the luminous section. The two sections thus each form a module as a structural unit. This allows the separate replacement of any defective parts regardless of the other section. The coupling ensures the power supply of the lighting section. However, this open passage can also be omitted if a wireless energy transmission is to be realized.

The passage is preferably formed in that both housings of the luminaire are at least partially open on their mutually facing sides in an overlapping region. In the simplest case, the passage can be formed by means of a (drill) hole of circular cross-section, through which a power supply cable passes.

Preferably, both housings are integrally formed with each other. Ie. there are no problems of stapling, as described above, and yet the operating device and possibly the lighting means are accessible from different locations of the lamp forth or housing enclosing them can be designed accordingly, since operating device and lighting means are arranged spatially separated from each other.

Alternatively, both housings are formed by means of two separate parts which are fastened to each other. The attachment can be done for example by means of concealed screws or by gluing due to the possible different dimensions of the two housings.

Preferably, a seal is arranged between the two housings, which abuts against these mutually facing sides of both housing at least liquid-sealing. Although the housing is formed in two parts, thereby the use of the lamp in wet rooms such as bathrooms, so as a wet room light, allows.

The operating housing may have a first passage opening on a first side, which does not face the luminaire housing, and which is closed by means of a detachably mounted cover. This allows access to the operating device for maintenance, replacement or other work.

Preferably, the luminaire is at least liquid-sealed in the region of the cover to the outside with respect to the luminaire. Ie. the use as a moisture-proof light is also possible in this case.

The seal between the cover and the operating housing is preferably formed by the cover is formed in the contact area with the operating housing of an at least liquid-sealing material. Ie. the lid itself forms the seal. This has the advantage that no further sealing parts are required. One possibility is the formation of the lid as a screw cap with an outer contact surface formed from rubber or the like. With this, the lid is preferably screwed, for example, in a formed in the through hole internal thread "cutting", so that the sealing effect arises. However, any other type of positive and / or positive sealing is conceivable.

Alternatively or additionally, an extra seal is arranged between the cover and the operating housing so that the operating housing is at least liquid-sealed to the outside in the area of contact with the cover. This makes it possible to manufacture the operating housing and lid from not (safe) sealing materials such as metal. In addition, no special sealing structures on the operating housing and lid are required, which simplifies their construction and increases the application width. The seal can simply rest flat on facing surfaces of the lid and the operating housing. The seal is thus at least on a first, one of the two housing-facing side to this one housing at least liquid-sealing. Alternatively, the seal can be glued liquid-tight on this side with this one housing. The same happens to the second, the other of the two housing facing side of the seal. The seal is thus at least a second fluid-tight on a second, the other of the two housing-facing side of this other housing or is glued to this liquid-tight. This design allows the use of a flexible seal with yet secure liquid seal. The advantage is that both housing can move relative to each other due to the flexibly formable seal. As a result, the housing, for example, be formed of different materials, the operating housing example of metal for grounding the lamp and the lamp housing made of transparent plastic optics. With temperature fluctuations, both housings have mutually different thermal expansion characteristics that can be compensated by the seal. Instead of providing a seal, both housings can of course be glued directly liquid-tight together.

The operating device is preferably designed such that it can be inserted through the first passage opening from the outside with respect to the luminaire and, if necessary, also removed again. This simplifies work on the operating housing in particular. The operating device can be removed as a whole, the work can be carried out on it, and finally the same or another operating device is used again.

If the operating device is designed as a module, the work is simplified even further. The modularity allows the formation of a sort of standard operating device, which is manufactured as a unit and then only used in the lamp and possibly electrically coupled. If it is defective, it can be replaced as a whole, which helps to minimize assembly time and costs.

Preferably, the operating device comprises a holder, are attached to the electrical functional elements of the operating device. Ie. all other (functional) elements can be permanently installed and thus positioned, except for any existing electrical lines. Any electrical couplings between them can therefore be so laid or dimensioned in length that they scrub nowhere when inserting the operating module or are also protected from the holder to the outside from mechanical influences. The latter is particularly possible if the holder is formed like a cage. Of course, the electrical lines can also be fixed to the bracket. Another form of electrical couplings may be male-female connections between two immediately adjacent functional elements. Last but not least, an electrical coupling can be formed by means of printed circuit board elements, which are arranged between two directly adjacent functional elements and electrically coupled to one another.

The operating housing preferably has a second passage opening on a second side, which does not face the luminaire housing, through which the operating device is electrically coupled to at least one external power supply line. This allows on the one hand, to arrange the power supply on the same side of the operating housing, at which there is access to the operating device. As a result, it can be realized that the power supply first has to be removed before the operating device can be removed, which increases operating safety. On the other hand, this second side may be a side other than the first side of the operating housing, preferably the opposite side. As a result, the electrical coupling of the lamp does not have to be removed. If the operating device is electrically connected to the power supply line by means of a plug-and-socket connection, it must only be removed from the operating housing. In this case, the electrical coupling with the power supply line is automatically disconnected.

In this second passage opening, a connection element is preferably used in particular releasably. The connection element is electrically coupled to the operating device and designed on a side remote from the operating device to be electrically coupled to the at least one power supply line. Ie. the external power supply can be removed. If the connection element is formed on an opposite side to the aforementioned cover, the operating device and connection element can be designed alternatively or additionally, when being pushed together at least electrically, but advantageously also mechanically coupled. This greatly facilitates the (dis) assembly of the operating device, since the installer no longer has to pay attention to the electrical coupling.

The operating housing is preferably at least liquid-sealed in the region of the connecting element to the outside, which benefits the use as a moisture-proof light.

The seal can be done as in the aforementioned cover. The seal between the operating housing and connecting element thus preferably arises in that the connecting element is formed in the contact region with the operating housing of an at least liquid-sealing material and / or a seal is arranged between the connecting element and the operating housing, so that the operating housing in the contact area with the connecting element to the outside in Regarding the lamp is at least liquid-sealed. There are therefore the same advantages as above the lid.

The aforementioned first side and second side are preferably formed by means of the same wall portion of the operating housing. There is thus only one access page. This allows the luminaire to be installed in places that are only open to one side. The operating housing can abut on all other sides of a wall of a room, frame or the like.

Alternatively, these sides are formed on two different, preferably opposite wall portions of the operating housing. Opposite wall sections have the advantage of being able to switch the operating housing with operating devices of other luminaires or devices in series, so that a kind of device or luminaire chain is created. This is particularly advantageous in large rooms such as halls, since in extreme cases only a single external power supply cable is necessary.

Further features and advantages of the invention will become apparent from the following description of preferred embodiments. Show it:

1 a luminaire according to an embodiment of the invention,

2 an exploded view of the light of 1 from the side of the luminaire housing,

3 an exploded view of the light of 1 from the side of the operating housing,

4 a sectional view of the light of 1 along a line AA in 1 .

5 a sectional view according to 4 a modified lamp and

6 a section of 5 enlarged in detail.

1 shows a lamp 1 according to an embodiment of the invention. The lamp 1 consists essentially of two housing parts 20 . 30 a lamp housing and a housing 50 ,

The operating housing 50 has a connection element at a rear end side 2 for electrically coupling to an external power supply line (not shown). At the opposite end is the operating housing 50 preferably by means of a lid 51 furthermore preferably finished moisture-tight.

The lid 51 is by way of example four screws 52 on the operating housing 50 attached, one of which is provided with reference numerals. The lid is centered 51 here a connection element 54 on, the example by means of a screw 53 on the lid 51 is attached. The connection element 54 is designed here as a connector and can be coupled accordingly with a corresponding female connector of an external power supply line at least electrically, but advantageously also mechanically.

The screw section 53 is at his the lid 51 facing side exemplified with an external thread, by means of which he in a corresponding internal thread in the lid 51 is preferably screwed sealingly. The connection element 54 is in the screw section 53 preferably pressed or otherwise insoluble or releasably attached thereto. The parts 51 . 53 . 54 may also be partially or wholly integral with each other.

Centered in relation to the operating housing 50 is a clamp 60 arranged, which in turn centrally a passage opening 61 has, by an unillustrated fastener is screwed, for example in the form of a screw through in a support member such as a wall or ceiling of a room. The clip 60 has right and left freestanding projections 62 on that the operating case 50 pinch. The projections 62 form clamping sections 62 the bracket 60 in terms of the operating housing 50 ,

2 shows the light 1 from 1 in an exploded view from the side of the housing part 30 So from one to 1 opposite side.

As can be seen, the operating housing 50 on the housing part 20 attached or integrally formed with this. The housing part 30 is from one of the operating enclosure 50 opposite side of the housing part 20 put on this. Preferably located between the two housing parts 20 . 30 an example circumferentially formed seal 7 , This ensures that one through the housing parts 20 . 30 and the seal 7 enclosed interior 5 is sealed to the outside preferably moisture-tight. In the interior 5 For example, there are four printed circuit boards 4 of which only one is provided with reference numerals. Ie. the housing parts 20 . 30 form a luminaire housing.

To the housing parts 20 . 30 or the interior 5 To seal to the outside, here are examples of brackets 40 provided with protrusions 41 the arrangement formed from the housing parts 20 . 30 , the seal 7 and in the interior 5 arranged parts such as the circuit boards 4 , embrace and thus both housing parts 20 . 30 fix each other. The brackets 40 have a substantially U-shaped cross-section, so that a respective recess 42 arises towards the housing parts 20 . 30 is open. However, it is any other mounting option for the housing parts 20 . 30 to each other (possibly only on the seal 7 ) possible, for example by means of screws.

On the circuit boards 4 are explained in more detail later, not visible here bulbs 6 arranged their light towards the housing part 20 radiate. Therefore, the housing part 20 at least in the transillumination area with regard to the of the bulbs 6 radiated light, but preferably completely from a transparent, ie for the light of the bulbs 6 permeable, material formed.

To protect this material from damage, the housing part has 20 in contact areas with the brackets 40 special areas as clamping sections 21 on, of which the clarity only one is provided with reference numerals. Also the housing part 30 advantageously has corresponding clamping sections 31 on, of which also only one is provided with reference numerals. Every clip 40 thus encompasses a pair of mutually belonging clamping sections 21 . 31 ,

Further preferably, there are respective pairs of clamping portions 21 . 31 with associated bracket at least partially or entirely of electrically conductive material such as metal. This allows, for example, the housing parts 20 . 30 to ground by a grounding wire from the interior 5 from the inside with at least one clamping section 21 is coupled. When placing the housing part 20 on or in the housing part 30 reach corresponding clamping sections 20 . 30 at the latest about the attached bracket 40 electrically in contact with each other. The the operating housing 50 facing side of the housing part 30 can be metallically coated and so a coupling with the operating housing 50 enable. This is advantageously via the connection element 2 and / or the connection element 54 electrically coupled to a grounding conductor of the external power supply line. Alternatively, the housing part 30 completely made of metal, so that the clamping sections 31 then could also be omitted.

As can further be seen, the operating housing 50 in the direction of the housing part 20 open, therefore preferably has no outer wall on this side. The housing part 20 has accordingly to the operating housing 50 facing side a through hole 22 on. The passage opening 22 In terms of its external dimensions, this corresponds essentially to the internal dimensions of the open side of the operating housing 50 , This creates a spatial connection between the inner space 5 and a later explained in detail recording room 57 of the operating housing 50 , This allows one in the case 50 recorded, also explained in more detail later operating device 70 with the four printed circuit boards here 4 to couple electrically and thus operate.

3 shows an exploded view of the lamp 1 from 1 from the same side as in 1 ,

The housing parts 20 . 30 and the operating housing 50 are shown attached to each other or formed integrally with each other. The operating housing 50 is shown open at the forward facing here front side. It has a cavity inside, which houses the receiving space 57 forms and in the example shown in the direction not designated interior 5 is open. Between the lid 51 and the operating housing 50 is preferably a seal 10 arranged. The seal 10 is by means of the lid 51 and the screws 52 on a frontal end of the operating housing 50 pressed pressed attached.

The screws 52 are from one of the operating enclosure 50 opposite side of the lid 51 through corresponding passage openings 58 of the lid 51 passed through and into a corresponding one of four here in the operating housing 50 frontally formed screw holes 56 screwed. The screws 52 thus fix the lid 51 on the operating housing 50 , and that's the seal 10 on the facing, frontal end of the operating housing 50 pressed pressed attached. For this purpose is the seal 10 formed circumferentially by way of example and therefore has a passage opening 12 on.

In the interior 57 is the operating device 70 arranged to operate the non-illustrated printed circuit boards 4 is provided. The operating device 70 mainly comprises an exemplary in cross-section L-shaped bracket 74 , at the ends of which holder 78 are arranged. The holders 78 serve the frontal holding a package, consisting essentially of several accumulators 71 and preferably a control circuit arranged laterally thereon 79 ,

The holders 78 advantageously not only serve to mechanically hold this arrangement 71 . 79 but also the electrical connection or coupling or performing electrical connection lines to this arrangement 71 . 79 from the outside. To the arrangement 71 . 79 to be able to supply with electrical energy is preferably in the lid 51 the aforementioned screw 53 screwed, which has the shape of a nut to the outside, and in the middle of the connecting element 54 is arranged for example in the form of a plug part. This plug part is used to attach a corresponding socket element that is neither shown nor explained in detail in the description. The resulting socket-plug connection allows both a mechanical and an electrical coupling of an external power and / or data line, not shown, with the arrangement 71 . 79 ,

The operating housing 50 points in the example shown on the interior 57 facing, opposite inner sides, preferably one rail 55 on, of which only a rudimentary is visible. The rails 55 extend towards each other and parallel to each other in the insertion direction of the holder 74 , So preferably parallel to the longitudinal extent of the operating housing 50 , They serve to insert the holder 74 in the operating housing 50 and thus for positioning and optionally positive and / or non-positive fixing of the holder 74 and thus the entire operating device 70 in the operating housing 50 , This allows the operating device 70 merely to mount by means of insertion, additional fasteners such as screws or the like are not required. The holder 74 has approximately in the middle a guide section 77 which is shaped to fit into the operating enclosure 50 can be inserted while the operating device 70 in the operating housing 50 as in a spring-groove connection is performed accordingly.

The guide section 77 can also be omitted or occur several times. Is there the leadership section 77 not, takes over the bracket 74 even the lead. For this purpose, it is then formed circumferentially in the circumferential direction or in the direction of the housing part 20 open.

4 shows a sectional view of the lamp 1 from 1 along a line AA in 1 ,

To recognize the two housing parts 20 . 30 and the operating housing arranged above it 50 , As can be seen, is a power supply line 72 through the operating housing 50 completely arranged throughout. About connection elements 73 . 76 is the arrangement 71 . 79 with the line 72 electrically coupled. The connection elements 2 . 54 such as 73 and 76 are mainly used for mechanical fixing of the pipe 72 , Is a maintenance made, for example, to accumulators 71 to exchange, the lid becomes 51 subtracted, and the operating device 70 is pulled out. The administration 72 is designed to be relatively long, thus enabling the operating device 70 to pull out without having to deduct the electrical power supply.

In summary, the operating device 70 (here with accumulators 71 ) within the operating housing 50 on the bracket 74 arranged as a removable carrier. After removing the lid 51 can the holder 74 frontally from the operating housing 70 be pulled out. Ie. for maintenance work is the operating device 70 then freely accessible. To prevent problems with the cabling of the control gear 70 with the bulbs 6 result is the operating device 70 preferably connected via a correspondingly sized cable loop with the LED board. This means that the operating device is pulled out of the additional housing, but remains permanently connected to the light sources via the cable, despite everything.

Finally, here are the holders 78 in the direction of the viewer protruding projections 75 educated. The projections 75 are preferably designed to be in 3 above the opposite rail 55 to come to rest and thus the holder 74 in the operating housing 50 along its mounting or insertion path in the operating housing 50 to lead. The projections 74 are advantageously also on the not visible here, opposite side of the holder 78 educated.

5 shows a sectional view according to 4 with a modified lamp 1 ,

As you can see, the line is missing here 72 , Instead, the arrangement is 71 . 79 via connectors with the connection elements 73 . 76 mechanically and electrically coupled. The energy supply from the outside via the connection element 2 and / or the connection element 54 , Ie. inside the operating housing 50 are preferably no lines at all. This simplifies the assembly, since the operating device 70 only has to be inserted and a line break is not to be feared. On the other hand, the wiring can be simplified to the effect that between possibly several, juxtaposed lights 1 just one line has to be laid. Alternatively, the electrical coupling can take place via a frame, which is not described in detail in the context of the invention.

6 shows a section of the lamp 1 from 5 enlarged in detail, and their left area in 5 ,

Here are the housing parts particularly well 20 . 30 to recognize, between which the preferably circumferentially arranged seal 7 is arranged. The seal 7 stands with the housing part 20 via a preferably also circumferentially molded or formed projection 23 positively and / or non-positively engaged.

In the interior 5 is the circuit board 4 with attached bulbs 6 towards the housing part 30 , which is preferably made entirely of transparent material, through the housing part 30 through to radiate their light to the outside, here so down and from the operating housing 50 path.

Between housing part 30 and circuit board 4 is still a light element in the example shown 8th arranged as an example in the form of a planar prism arrangement. The arrangement can by means of clamping between the circuit board 4 and housing part 30 take place, or the light element 8th is on the circuit board 4 or on the housing part 30 attached or integral with the housing part 30 educated.

The holder 78 exemplarily couples with the control circuit 79 for the operation of printed circuit boards 4 and the light-emitting means mounted thereon is provided. An electrical coupling to the circuit board 4 For example, about the lead 75 and the above rail 55 respectively. The lead 75 and the contact rail 55 then have the function of busbars. The rail is not visible in the illustration shown. Ie. the insertion of the operating device 70 is sufficient to the operating device with the bulbs 6 to couple electrically. This further simplifies the assembly.

The lid 51 indicates at its the operating housing 50 facing side here a circumferentially formed projection 59 on. The lead 59 stands from the other cover 51 in the direction of the operating housing 50 emerges and tapers towards the free end. This is the lid 51 possible, a him facing, also preferably circumferentially formed projection 11 the seal 10 between itself and the front end of the operating housing facing it 50 pinch. This is done by tightening the screws 52 , causing the lid 51 here with the connection element 54 in the direction of the operating housing 50 is urged. This will get the lid 51 , the seal 10 and the operating housing 50 preferably at least liquid-tight in plant. Ie. by this arrangement is the lamp 1 Also in this area protectable against the ingress of moisture, so that the entire lamp 1 can be used as a wet room light.

The invention is not limited to the prescribed embodiments.

If the function as a moisture-proof light is not necessary, the seal (s) can / can 7 . 10 omitted or less sealing trained and / or arranged.

The housing parts 20 . 30 can, rather than with a seal 7 . 10 to be provided, also glued together or otherwise attached to each other. For example, it is suitable for PU foam or silicone adhesive. The same applies to the attachment of the operating housing 70 with respect to the housing part 30 , Even if all three housings (parts) 20 . 30 . 50 would be permanently attached, for example, by gluing together, would be the operating device 70 continue through the opening 51 accessible through.

The assembly of the light 1 Can be done by the housing part 30 is removed. Ie. the lamp 1 theoretically could already be mounted on a wall or on a rack and then mounted. Or the operating device 70 is, as explained above, through the through hole 58 pushed through and with the bulbs 6 electrically coupled.

Due to the spatial separation of operating device 70 and bulbs 6 It is possible, particularly flat luminous body or luminous housing by means of the housing parts 20 . 30 manufacture. These can rest very flat on the wall. Unsightly braces no longer have to be installed, even if they are in relation to 2 are shown. In particular, the clip-free assembly of the housing parts allows 20 . 30 to each other a lower or no mechanical stress in one or both housing parts 20 . 30 ,

The holder 74 can also be part of the electrical coupling. If it is made of a current-conducting material, or has electrical coupling paths similar to printed conductors on a printed circuit board, it can serve, for example, as a grounding. The operating device 70 is over the bracket 74 for example via the rail 55 with the operating housing 50 electrically coupled and thus grounded via a thus electrically coupled ground terminal.

Is the holder 74 Cage-shaped, it can provide electromagnetic shielding for the control gear 70 Offer.

Instead of inserting the bracket 74 Of course, in any known manner on the operating housing 50 be releasably or permanently attached, such as by jamming, Verrastens, gluing, etc.

The light element 8th may be omitted or replaced by any other type of lighting element. For example, it may be formed like a frosted glass, so that the light 1 despite punctually illuminated lighting elements 6 a diffused light radiates.

Instead of LEDs, any type of light source can be used, for example an OLED. Essential to the invention is that the height of the through the housing parts 20 . 30 bildbaren luminaire housing only from the lighting elements 6 (possibly including printed circuit board (s) 4 ), but not more of the wiring or of a necessary operating device 70 ,

Instead of on a wall or ceiling of a room, the light can 1 be mounted on a frame, which is arranged for example behind a suspended ceiling. The frame could then, for example, the grounding of the lamp 1 take.

The modularity of the entire structure of the lamp 1 allows a quick replacement of any defective parts of the lamp 1 ,

By the invention, the actual lighting element, ie without operating device 70 , be formed by an extremely flat unit, so in particular offers for lights with a flat design.

The assembly with the flat LED matrix is at the bottom by a flat light emitting element here in the form of the housing part 30 closed and at the same time also on its circumference and on its back, by means of the housing part 20 is formed, sealingly encased by the housing part thus formed. The operating device 70 itself is now not arranged in this unit but in one by means of the operating housing 50 trained additional housing. The additional housing 50 is located at the back of the unit. The back is the case 30 opposite side of the housing part 20 , The additional housing is preferably elongated and just in particular for receiving the operating device 70 and possibly also one or more batteries 71 designed. The operating housing 50 becomes sealed with the actual luminaire housing 20 . 30 or the above-mentioned unit connected, which is achieved on the one hand by means of a screw and on the other hand can be ensured by gluing the attachment housing with the actual lamp housing. It remains only in the present case the front side of the opening 58 via which access to the interior 57 of the additional housing 50 is obtained. The opening 58 can with the help of the preferably unscrewable lid 51 be closed or opened, in which case with the help of an O-ring as a seal 10 a seal is achieved. As already mentioned, according to the embodiment, the removable lid 51 the only area about access to the interior 57 of the additional housing 50 and to the actual luminaire, so that the O Ring may be sufficient as the only sealing measure.

Instead of in 4 illustrated, relatively long connecting cable 72 inside the operating housing 50 , which is placed to a cable loop, this connecting line could also be made shorter. In this case, then would have a corresponding terminal, for example, behind the lid 51 set and made accessible via this, then the optional loosening and connecting the wiring. Or there is another connection, for example in the form of the aforementioned male-female connection.

The provision of two connection elements 2 . 54 especially on the lid 51 opposite side of the operating housing 50 is only required if the light 1 in the context of a through-wiring with several other lights to be electrically connected. However, this wiring is not absolutely necessary, ie the corresponding connection element 2 . 54 can be omitted. In the case of the lid 51 this would also be the screw part 53 affect.

The connection elements 2 . 54 can be omitted individually or in total. In addition, they can be designed in any form, for example, as a connector according to the USB standard, if the bulbs 6 have a correspondingly low energy consumption.

The operating device 70 may include a voltage transformer, for example in the form of a transformer, so that the bulbs 6 can be connected to an AC voltage, although they require a DC voltage.

Also, the operating device 70 be exchanged for another if it is defective or change the parameters of the lighting mode, for example, when the terminal voltage is changed, for example, from AC to DC or vice versa. Another case may be that the light 1 be changed from a self-sufficient to a centrally controlled operation, for example in the context of a building network. Then the lamp needs 1 in addition, the possibility of data exchange with a central building or another type of control center. Or it is a communication from lamp to lamp to be realized so that a lamp can activate another, for example, if a sensor in the lamp determines that an object moves in the direction of an immediately adjacent light.

Even if the invention, in particular with flat LEDs as a light source 6 is of advantage, as this particularly flat running wet room lights are feasible, the invention is of course applicable to all other types of lights.

As a result, the invention provides a very simple design and to be installed and adaptable to various applications and retrofit lamp, which can be used in particular in wet rooms, such as bathrooms, and yet very easy to assemble and maintain.
