Description

The present invention relates to a luminaire, which has a luminaire housing with an opening for emitting light, sockets for mounting and power supply at least one light source and a device carrier for holding the sockets and / or equipment for operating the light source, within the luminaire housing with this is connectable.

Narrow, elongated lights such as the so-called Slotlight lamps of the Applicant, which are used both for Deckenein- / cultivation and in suspended or pendulum manner, are known from the prior art. Such lights usually have a U-shaped profile body as a light housing, with which the other components are connected.

However, the profile body influences the light output of the lamp, since it usually has projections and other contours for holding the other components of the lamp, through which the light emitted is influenced. This creates an overall inhomogeneous photo. In addition, can be degraded by the inner contours of the housing, the efficiency of the lamp.

Another problem with lights that are embedded in a ceiling or a wall is that it often proves difficult to wire the lamp or to wait for the top of the lamp mounted components. This is usually only possible when the lamp is dismantled.

The present invention also relates to lights that produce a long band of light. The light band can be several meters long. However, no fluorescent tubes are known which have such a length. Therefore, several light sources are mounted one behind the other. In order to avoid darker streaks in the photograph at the height of the frames, the light sources are attached slightly overlapping each other. This staggered arrangement is also known as Tetris arrangement of the applicant.

In the aforementioned staggered arrangement of the light sources, at least part of the sockets of the one light source are located immediately adjacent to the adjacent light source. As a result, the corresponding version is exposed to constant UV exposure and heat, which leads to embrittlement of the socket.

The present invention is therefore first of all the object to make the light image of the lamp described above uniformly while improving the efficiency of the lamp.

The object is achieved by a luminaire according to claim 1. Advantageous developments of the invention are the subject of the dependent claims.

Other objects are to avoid embrittlement of the sockets of light sources in an overlapping arrangement of the light sources and to construct the lamp such that the wiring can be made without the lamp must be dismantled for this purpose.

According to the present invention, a luminaire is proposed which comprises a luminaire housing having an opening for emitting light, sockets for holding and supplying power to at least one light source and a device carrier for holding the sockets and / or operating means for operating the light source inside the luminaire housing can be connected to this, wherein the device carrier simultaneously forms one of the opening for emitting light facing reflector.

The inventive lamp is characterized by the fact that it produces a very uniform photo. The disturbing influence of the profile body on the light image is minimized by the device carrier is designed as the opening for light emission facing reflector. An equipment carrier configured as a reflector largely conceals the inside of the profile body, so that the light image is no longer adversely affected by the internal contours of the housing. Furthermore, the efficiency of a luminaire can be increased by the present invention.

Preferably, the equipment rack is painted white. Furthermore, the device carrier with the lamp housing is preferably latched. Such locking is possible, for example, by appropriate hooks and / or projections on equipment carrier and lamp housing.

In a preferred embodiment, the device carrier on additional means for increasing the efficiency of the lamp. It is a further reflector, which is designed such that the light is reflected as possible in the desired direction of emission of the lamp.

Preferably, the lamp housing is formed by an aluminum profile and the device carrier is formed in cross-section C-shaped.

In a further preferred embodiment of the lamp, the device carrier is connected to its opening facing the light output side with electronic ballasts and / or through-wiring.

Further, the light preferably in the region of the opening for light emission on a part-permeable plate as cover profile.

In order to produce a long band of light, the lamp has a plurality of rod-shaped light sources, which are arranged slightly offset from one another and overlap at their end sides over a short length.

Another embodiment of the present invention is that the device carrier has tabs which are folded down towards the bottom so that they shield the sockets for holding the light sources in the overlap. This protects the sockets against the heat and UV radiation generated by the immediately adjacent light source. In this way, the life of the lamp is considerably extended.

According to a further embodiment of the present invention, the device carrier on pivotable clamping straps on which there are means for wiring the lamp. This ensures that the wiring of the luminaire can be made without having to disassemble the luminaire.

If a very long light band to be generated, it is advantageous if the equipment carrier is constructed from several device carrier sections. In this case, the tabs are arranged at the respective ends of the equipment carrier sections.

The invention will be explained in more detail with reference to the accompanying drawings.

Fig. 1 shows the inventive lamp 1 in a perspective view. The luminaire 1 has an elongate luminaire housing 2 which has on one longitudinal side a light exit opening in which an at least partially transparent plate 3 is arranged. Also inside the luminaire 1 are a device carrier 4 and at least one light source (such as a lamp) 5.

In the luminaire housing 2 is preferably a narrow elongated aluminum extrusion profile. The profile is essentially U-shaped, with the light being emitted via the opening of the U-shape. At the end faces 6, the profile is closed in each case by connecting caps, not shown, so that the light output can be made only through the opening.

Fig. 2 shows the inventive lamp 1 in cross section. As shown, the housing 2 has a plurality of projections or hooks 7, 8, 9, 10, with which the equipment carrier 4 can be latched. For this purpose, the equipment carrier 4 corresponding means for locking. This may be, for example, the projections 11, 12, which are clamped by the hooks 7, 9.

At the top of the equipment rack 4 is connected to various devices 13 and carries the means 14 for wiring the lamp. The reference numeral 13 designates in Fig. 2, an electronic ballast 13, which is used to operate the light source 5. The reference numeral 14 designates means for fixing the wiring of the lamp. These are, for example, terminals with which cables are fastened to the upper side of the equipment carrier 4.

The luminaire housing 2 shown in FIG. 2 is, as already mentioned, a naturally anodized, extruded aluminum profile. Such a profile element has internal contours which influence the light image generated by the light 1. In the example shown, it is the Verrastvorsprünge 7, 8, 9, 10th

By these inner contours, the light output of the lamp 1 is impaired and there is an uneven photo, which produces an unpleasant optical impression for a viewer. In addition, the efficiency of the luminaire 1 is reduced by said inner contours.

To avoid these problems, the C-shaped device carrier 4 is now used according to the invention to cover these inner contours, so that the light image can not be adversely affected by these contours. Furthermore, the device carrier 3 is equipped according to the invention with a reflective surface. The device carrier 3 thus reflects the light incident on it, whereby the efficiency of the lamp 1 is increased. The luminaire 1 according to the invention with the reflective equipment carrier 3 accordingly produces a uniform appearance over the entire width and length of its emission opening 17.

In order to improve the efficiency of the lamp 1 even further, the device carrier 4 is additionally equipped in the illustrated in Fig. 2 preferred embodiment with a further optics 16, which is also reflective. The optic 16 is shaped such that the light is preferably reflected towards the emission opening 17.

The emission opening 17 is equipped with an at least partially transparent plate 3. By this plate 3, the light is scattered, so that the light output over the entire emission opening 17 is carried away very homogeneous.

The equipment carrier 4 is further configured such that a second light source (such as a lamp) 18 could be disposed adjacent to the light source 5. The housing 2 of the lamp 1 is, as indicated in Fig. 1, designed narrow and elongated. In order to achieve a uniform light output over the entire length, a plurality of elongated light sources 5, 18 are arranged one behind the other in the housing 2. These light sources are offset from one another, so that their respective ends overlap slightly. This type of staggered arrangement results in no darker areas at the junctions between two light sources.

An example of such a staggered arrangement of two light sources 5, 18 can be seen in FIG. FIG. 3 shows a perspective view of the device carrier 4 according to the invention. The device carrier 4 has sockets 19, 20 which receive the light sources 5, 18.

Due to the staggered arrangement of the light sources 5, 18, the socket 19 is located directly next to the light source 18 and the socket 20 is located immediately adjacent to the light source 5. Therefore, the sockets 19, 20 in the on state of the lamp 1 is constantly high Temperatures and exposed to strong UV radiation, which leads over time to the fact that the sockets 19, 20 become brittle and fragile due to this load.

To avoid this problem, the equipment rack 4 is therefore further equipped with tabs 21, 22. The tabs 21, 22 are positioned so as to shield the sockets 19, 20 from the UV radiation and the heat generated by the light sources 5, 18.

It has been found that by this shielding with the aid of the tabs 21, 22, the temperature at the sockets 19, 20 can be reduced by up to 10 ° C. This measure according to the invention thus leads to a significantly lower load on the sockets 19, 20, so that the service life of these sockets 19, 20 and thus of the entire luminaire 1 can be significantly increased.

The equipment carrier 4 shown in Fig. 3 is composed of a plurality of equipment carrier sections 23, 24. The device carrier sections 23, 24 close to each other seamlessly and have at their ends in each case the above tabs 21, 22. The tabs 21, 22 are designed such that they can be bent over.

Incidentally, such a tab 21 can also be seen in the exemplary embodiment according to FIG. 2.

Fig. 4 shows a perspective view of the top of an inventive device carrier section 23, 24. At the top of the device carrier section 23, 24 are an electronic ballast 13 for driving the light sources 5, 18 and a plurality of terminals 25, through which the wiring of the lamp 1 is attached.

In Fig. 4 can also be seen that the device carrier sections 23, 24 are divided into two at their end faces 26,27. One half of the end face 26, 27 is formed longer than the other half. This results in an offset, which is reflected in the staggered arrangement of the light sources 5, 18. The sockets 19, 20 for the light sources 5, 18 are mounted according to the staggered arrangement such that the light sources 5, 18 overlap in their end regions.

The reference numeral 21 designates here a tab which has been folded down and shields in the present position, the socket 19 from the heat and UV radiation of an adjacent light source.

Since the inventive lamp is often installed in a wall or ceiling, the installation or a possible repair of the wiring may be difficult under certain circumstances. Also arranged on the top of the device carrier 3 electronic ballast 13 is difficult to achieve.

In a preferred embodiment, the equipment carrier 4 for this reason, a pivotally mounted clamping strap 30. This clamping strap is shown for example in Fig. 5. In particular, the means 31 for wiring the light source 5, 18 are arranged on the clamping plate 30. Once the luminaire 1 has been installed, the clamping lug 30 can be folded down at any time and the wiring is easily accessible for a fitter.

Preferably, a plurality of clamping straps 30 are arranged distributed over the equipment carrier 4, so that when installing the lamp 1, a continuous wiring over the entire length of the lamp 1 can be achieved without problems. Through the use of a plurality of clamping straps 30, a through-grinding of the through-wiring to the next device carrier section 23, 24 is made possible in a simple manner, without the device carrier sections 23, 24 having to be dismantled.

In Fig. 5, the latching device 11, 12 can also be seen, with which the device carrier 4 is latched to the lamp housing 2.

6 again shows a device carrier section 23, 24 according to the invention. FIG. 6 shows the device carrier section 23, 24 before the side parts are bent over in the course of the production process.

The device carrier section 23, 24 also has various openings and holes 32 which are configured to receive further components or the wiring. The holes are also suitable to perform a tool, such as a screwdriver. In this way, the locking of the device carrier 4 can be solved and it can be removed from the lamp housing 2.

Comparable holes and openings 32 are also arranged on the clamping plate 30.

Furthermore, two circles A, B are shown in FIG. 6. The circle A marks the end of the equipment carrier portion 23, 24 and circle B marks the clamping plate 30. Fig. 7 shows an enlarged view of the circle A and Fig. 8 shows an enlarged view of the circle B. Again, like reference characters designate like components.

Fig. 9 shows the implement carrier section after the tab 21 and the side parts have been folded down.

In particular, with longer light bands a plurality of equipment carrier sections 23, 24 are arranged one behind the other. In this case, the device carrier sections 23, 24 as already discussed at the ends a slight offset to allow the staggered arrangement of the light sources 5, 18. At the end of such a light band then a short, specially designed device carrier end piece 33 is used. This can be seen in FIGS. 10 and 11. The tool carrier end piece 33 has an offset only on one end side and is just completed on the opposite end side. Furthermore, the device carrier end piece also has the components already known from the device carrier sections 23, 24, such as a tab 21, bores 32, a clamping lug 30, sockets 19, 20 and means 11, 12 for latching to the housing 2.

In Fig. 11, a circle C is further drawn, which marks the clamping plate 30. Fig. 12 shows an enlarged view of this circle.

Finally, FIGS. 13 to 16 show various possibilities for arranging the luminaire 1 according to the invention. The luminaire 1 can accordingly be placed in the ceiling (FIG. 13), mounted on the ceiling (FIG. 14), suspended from the ceiling on a pendulum (FIG. 15) or horizontally or vertically aligned in a wall (Fig. 16).

Overall, the design of the device carrier 4 and the device carrier part and -Endstücke 23, 24 and 33 as reflectors, the light image of the lamp 1 is significantly improved, since it now appears more homogeneous and at the same time increases the efficiency of the lamp 1 has been.

The further measures according to the invention help to facilitate the assembly work and to protect the luminaire from aging phenomena.
