Luminaire with reflective gear tray

The present invention relates to a luminaire, which has a luminaire housing with an opening for emitting light, sockets for holding and power supply at least 5 of a light source and a device carrier for holding the sockets and / or equipment for operating the light source, which is connectable within the lamp housing with this , having.

Narrow, elongated lights, such as the so-called Slotlight lights 10 of the Applicant, which are used both for the ceiling installation / in a suspended or suspended 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 supporting the other components of the lamp, by which the emitted light is influenced. This creates an overall inhomogeneous photo. In addition, the efficiency of the luminaire can be degraded by the inner contours of the housing. 20

Another problem with luminaires embedded in a ceiling or wall is that it is often difficult to wire the luminaire or to maintain components attached to the top of the luminaire. This is usually only possible when the lamp is dismantled. 25

The present invention relates to luminaires 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 stripes in the light image 30 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 a portion of the sockets of the one light source are located immediately adjacent to the C: \ DOCUME_L \ SS \ LOCAL ~ l \ Temp \ P3 5202_Text.d < i ··········································································· ··· ···· · * 2 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 based on the first object 5 to make the light image of the lamp described above uniform and at the same time to improve 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. 10

Other objects of the present invention are to avoid embrasure 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. 15

These objects are achieved by lighting according to claims 14 and 15, respectively.

According to a first aspect of the present invention, a luminaire is proposed, which has a luminaire housing with an opening for light emission, 20 sockets for holding and powering at least one light source and a device holder for holding the sockets and / or equipment for operating the light source, which is inside the Luminaire housing is connectable to this, has, wherein the device carrier simultaneously forms one of the opening for emitting light facing reflector. 25

The erfmdungsgemäße 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. A designed as a reflector gear tray 30 largely covers the inside of the profile body, so that the light image is no longer negatively influenced by the inner contours of the housing. Furthermore, the efficiency of a luminaire can be increased by the present invention.

Fig. 1 shows the lamp 1 according to the invention 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 25 is arranged. In the interior of the lamp 1 are also a device carrier 4 and at least one light source. 5

The luminaire housing 2 is preferably a narrow, elongated aluminum extrusion profile. The profile is essentially U-shaped 30, wherein the light is 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 luminaire 1 according to the invention 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 5 projections 11, 12, which are clamped by the hooks 7, 9.

At the top of the equipment carrier 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 10. 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 natural 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, 8,9,10.

By these inner contours, the light output of the lamp 1 is affected and there is an uneven photo, which creates 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

Photo can not be negatively influenced 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 device carrier 3 accordingly generates a uniform appearance over the entire width and length of its emission opening 17.

In order to further improve the efficiency of the luminaire 1, the device carrier 4 in the preferred embodiment shown in FIG. 2 is additionally provided with a C: \ DOCUME-l \ SS \ LOCALE-l \ Teinp \ P35202_Text.dc ··· · · • · • · • · · · ·

• ·························································································· other optical equipment 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 5. 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 device carrier 4 is further configured such that in addition to the lamp 5, a second lamp 18 could be arranged. The housing 2 of the lamp 1 is, as indicated in Fig. 1 10, designed narrow and elongated. In order to achieve a uniform light output over the entire length, a plurality of elongated lamps 5, 18 are arranged one behind the other in the housing 2. These lamps are offset from each other, so that each overlap their ends slightly. This type of staggered arrangement results in no darker areas at the junctions between two lamps.

An example of such a staggered arrangement of two lamps 5, 18 can be seen in 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 lamps 5, 18.

Due to the staggered arrangement of the lamps 5,18 is the version 19 immediately adjacent to the lamp 18 and the socket 20 is located directly next to the lamp 5. Therefore, the sockets 19, 20 in the on state of 25 lamp 1 constantly high temperatures and exposed to strong UV radiation, which over time, the sockets 19, 20 become brittle and prone to breakage due to this load.

To avoid this problem, the device carrier 4 is therefore further equipped with tabs 21, 30 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. C: \ DOCUME-l \ SS \ LOCAL-l \ Temp \ P35202_Text.d. Λ

··· · · · · · · · · ···

It has been found that by this shielding with the help of the tabs 21,22, the temperature of 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 device carrier 4 shown in FIG. 3 is composed of a plurality of device 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. In this case, the tabs 21,22 are designed such that they can be bent.

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 upper side of a device carrier section 23, 24 according to the invention. 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. 20 can also be seen in Fig. 4 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 longer than the other half. This results in an offset, which is reflected in the staggered arrangement of the lamps 5,18. The sockets 19, 20 for the lamps 5, 18 are mounted according to the staggered arrangement such that the lamps 5, 18 overlap in their end regions.

Reference numeral 21 here denotes a tab which has been folded down and, in the present position, shields the socket 19 from the heat and UV radiation of an adjacent light source. 30

Since the lamp according to the invention 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 device 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 lug 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 tabs 30 are distributed over the device carrier 4 10, so that when installing the lamp 1, a continuous wiring over the entire length of the lamp 1 away can be easily achieved. 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 having to disassemble the device carrier sections 23, 24.

In Fig. 5 also the locking device 11,12 can be seen, with which the device carrier 4 is latched to the lamp housing 2. 20 Fig. 6 shows again a erfmdungsgemäßes equipment carrier portion 23,24. In Fig. 6, the device carrier section 23,24 can be seen before the side parts are bent in the course of the manufacturing process.

The device carrier section 23,24 also has various openings and 25 holes 32 which are configured to receive other 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 bores and openings 32 are also arranged on the clamping plate 30. C: \ DOCUME-l \ SS \ LOCAL-l \ Temp \ P35202.Text d < 30 1 ············································································

In Fig. 6, two circles A, B are further drawn. The circle A marks the end of the device carrier section 23, 24 and circle B marks the clamping strap 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 numerals 5 denote like components.

Fig. 9 shows the equipment rack section after the tab 21 and the side panels have been folded down. 10 Especially with longer Lichtbändem several device carrier sections 23, 24 are arranged one behind the other. In this case, the device carrier section 23,24 as already discussed at the ends of a slight offset to allow the staggered arrangement of the lamps 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, also the device carrier end piece already known from the equipment carrier sections 23,24 components, such as a tab 21, holes 32, a clamping plate 30, sockets 19,20 and means 11,12 for locking with the housing 20 on ,

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). 30

Overall, the design of the device carrier 4 and the device carrier part and end pieces 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 the efficiency of the lamp 1 was increased.
