LIGHT BZW. LIGHTING ARRANGEMENT WITH LONG BEARING ELEMENT AND SOLDERABLE LIGHTING MODULE

The present invention relates to a luminaire or a lighting arrangement, wel¬che an elongated support member on which at least one light module is releasably befes¬tigbar.

Lights or lighting arrangements of the type described above can be realized in different ways. In particular, so-called. Light band systems, which an elongated support element often in the form of a U-shaped support rail AulWeisen.Innerhalb the support rail extending in the longitudinal direction of lines for power supply and for signal transmission, which can then be arranged on the support rail so-called lamp units. Depending on the configuration of the mounting rail with the lines running therein, the lamp units can be mounted at fixed positions or freely at any point over the entire length. By means of special contacting and locking elements, both a mechanical fastening of the lamp unit to the mounting rail is achieved and a contacting of the cables is carried out.

In addition to these light band systems, which have almost any length and can extend esp. Over very large distances away, but also Ein¬zellenuchten are used, which are basically based on a similar principle. Again, an elongate support member is provided which as central holding element for all the essential components of the luminaire is used. Esp. are on this support element in the rule means for fixing the lamp eg. On the ceiling of a room and a Betriebs¬ arranged to provide a supply voltage for the light source. The lamps themselves are then part of individual modules which are arranged on the carrier element and are connected to the operating device via electrical connection means. Usually, several individual lighting modules are used, which can be replaced for one another.

This above-described embodiment with interchangeable lighting modules anzetzichich esp. Then, when used as light sources LEDs. The reason for this is that LEDs have to be protected against external influences in comparison with conventional light sources such as light bulbs or fluorescent lamps. One reason for this is that inadvertent contact of LEDs can often lead to so-called ESD damages, that is to say damages which are attributable to unwanted electrostatic discharges. Furthermore, LEDs are usually arranged on boards, in which case the conductor tracks used for the power supply of the LEDs are freely accessible. In this case, there is the danger that, if the LEDs or the circuit board are accidentally stirred, current-carrying elements are also touched, which entails the risk of an electric shock. For this reason, according to the corresponding safety regulations, LEDs are to be arranged in a particularly protected manner within the luminaire, which usually makes it more difficult to replace defective LEDs or LED boards. Such work can, as a rule, only be carried out by trained electricians or by the luminaire manufacturer himself become. In the case of the above-mentioned interchangeable lighting modules, however, this problem does not exist because then the LEDs are protected within the module and only the module as a whole must be connected to the operating device of the light. That is, the replacement of individual modules is also easy to carry out by the end user.

In the support elements of these lights or the support rail of an elongated light strip system are usually made of sheet metal or aluminum profile elements. For manufacturing reasons, these elements are usually open on their front sides and must then be completed by special Stirnteil optical reasons. These are usually placed on the profile part and there, for example. With

Help fixed a screw.

The present invention is now the task of facilitating the attachment of the end caps to such support elements, so that the assembly of a light or a lighting system is associated with a lower workload.

The object is achieved by a luminaire or a lighting arrangement comprising the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

The solution according to the invention is based on the idea of designing the end parts in such a way that they can be detached from an end region of the support element in a simple manner, in which case they are subsequently fixed by the luminous module arranged on the support part.

According to the present invention, therefore, a lamp or lighting arrangement is proposed with an elongate support member, wherein the lamp or Beleuchtungsan¬ order further comprises at least one light module, which is releasably attachable to the support member. Furthermore, end pieces are provided for the support element, which can be arranged in each case at one end region of the support element, wherein the end parts are fixed by the light module fixed to the support element.

By the solution according to the invention, therefore, a separate operation of the fastening gens of the end parts on the support element of the lamp or lighting arrangement can be saved. Instead, the end parts are automatically fixed when arranging the light module or the light modules on the support element, so that thanks to the inventive solution weiter also special fasteners are no longer required.

Preferably, the carrier element is adapted to hold a plurality of lighting modules in the longitudinal direction arranged one behind the other. In this case, in each case the first and the last light module are then provided to fix one of the two end parts in each case. According to a particularly preferred embodiment, the means by which the light modules fix the end pieces are comparable to the means by means of which the light modules are arranged on the support element. In other words, in a preferred exemplary embodiment of the invention, the lighting modules are latched to the carrier element, with the front end parts likewise being latched to the lighting module in a similar manner. For this purpose, on the one hand, corresponding latching recesses may be formed on the carrier element, in which latching latches of the or the lighting modules intervene. Corresponding latching recesses are then also provided on the front parts. The end parts themselves are preferably pushed onto the carrier element sooner from the respective front side. In this Positi¬on then the lighting modules can be arranged on the support member and fix the Stirnteilein the inventive manner.

Ultimately, therefore, the attachment of Stirntei¬len to support elements of lights or lighting arrangements is simplified by the inventive solution.

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

As a preferred embodiment of the present invention, a single luminaire will be described below. However, as already mentioned, the concept according to the invention can also be used for larger lighting arrangements, in particular for so-called light band systems.

Figures 1 and 2 show different views of the generally provided with Bezugszei¬chen 1 inventive lamp. In the illustrated embodiment, the luminaire 1 is designed as a pendant luminaire and, in this case, can be fastened via at least one suspension element, in the illustrated case over a plurality of cables 2 to a support element (not shown), for example to the ceiling of a room. In a slightly modified way, however, the luminaire 1 according to the invention could also be used as a ceiling-mounted luminaire.

As can be seen in the figures, the luminaire 1 is designed to be elongated overall along a longitudinal axis L. The shape of the luminaire 1 is determined in the first line by a carrier element 5, which represents the central element of the luminaire 1 and on which all other components are arranged or attached. An essential feature of this support element 5 is that this forms on its underside or its light emission side a later described in detail U-shaped receiving area in which a plurality of lighting modules can be arranged interchangeable. The carrier element 5 is preferably formed by an aluminum profile, which is closed at its two end-side end portions by end caps 15, which in turn are detachably arranged on the carrier element 5 and fastened in the manner described in more detail below be¬ writing.

FIG. 6 shows the end region of the carrier element 5 from the underside, wherein now the receiving region 6 for the exchangeable lighting modules can be seen. This receiving area is formed by a bottom surface 7 and two downwardly directed U-legs 8 extending on both sides of the bottom surface 7. Together with the already mentioned end elements or end caps 15, the obliquely cup-shaped receiving region 6, which is U-shaped overall, is thus formed. In this case, a plurality of lighting modules - in the illustrated embodiment, 14 light modules - are arranged, one of which is shown in Figure 5 in a perspective view.

The light module 20 is thus formed approximately cuboid. As can be seen in particular from the sectional illustrations of FIGS. 7 and 8, the lighting module 20 consists of a cup-shaped, so-called lens carrier 21, which forms a bottom surface 22, which forms the light emitting surface of the light module 20, and four side walls 23, 24. In this case, two latching tabs 25 are respectively formed on the two shorter side walls 24, via which fastening takes place on the carrier element 5 of the luminaire 1. As can be taken from the illustration of FIG. 6, corresponding recesses or slots 9 are formed for this purpose in the bottom surface 7 of the receiving region 6 of the carrier element 5, in which the detent tabs 25 of the lighting module 20 engage.

The bottom surface of the light module 20 is formed by the back of a board 30 with several arranged thereon, preferably matrix-like distributed LEDs 31 (see Figure 7). These LEDs 31 represent the light sources of the light module 20, the LEDs 31 being associated with different optical means for influencing the light output.

As can be seen in Figure 7, 21 Lin¬senkörper 26 are formed in the central region of the lens carrier, which are each associated with individual LEDs 31. By contrast, the light of the LEDs 31 a located in the edge region should not be emitted with the aid of lenses, but rather cause a diffusely illuminating surrounding frame. This is achieved by a special diffuser frame 35, which is inserted into the lens carrier 21 and compared with the lens carrier 21, which preferably consists of a clear material, is formed of a light-scattering material or contains light-scattering particles. It should be noted, however, that the design of the optical elements of the individual lighting modules could also be designed otherwise, if another light emission is desired. The design of these optical elements is not relevant to the core idea of the present invention. It is essential that one or more of the lighting modules 20 are fastened to the carrier element 5 of the luminaire 1, so that an appearance image results from the underside or the light emission side of the luminaire 1, as shown in FIG.

The rear side of the light module 20 forming LED board 30 is locked to the Linsenträ¬ger 21. For this purpose, corresponding latching elements 27 are formed on the two side walls 23, which cooperate with the board 30 in such a way that they can be easily placed on the lens carrier 21 from the rear side and then pressed down. In this way, a stable structural unit is formed, by means of which in turn the individual LEDs 31 are efficiently protected from external influences.

The power supply of the arranged on the support member 5 lighting modules 20verfolgen using special contacting means comprising spring contacts 41 in the illustrated embodiment, which cooperate with arranged on the back of the LED board 30 Kontakt¬felder 35. The spring contacts 41 are here each arranged on a contact block 40 which can be recognized in FIG. 7, which protrudes through a corresponding recess 10 in the bottom surface 7 of the receiving region 6 of the carrier element 5. That is to say, these spring contacts 41 are accessible from the receiving region 6 of the carrier element 5 in such a way that they come into contact with the contact fields 35 of the light emitting module 20 when the lighting module 20 is inserted. As a result, the electrical connection between the spring contacts 41 and the lighting module 20 is ensured so that it is connected to the actual means for providing an operating current for the LEDs 31.

As can be seen from the illustration of FIG. 5, a multiplicity of contact fields 35 are formed on the rear side of the LED board 30, wherein, depending on the mode of operation of the luminaire 1, not all contact fields 35 must be used. Among other things, this depends on whether only a simple switching on and off of the modules 20 is provided or these should enable an individual controllability. In the illustrated embodiment, only two spring contacts 41 are used, so that therefore the modules 20 are supplied exclusively with a suitable supply voltage or a supply current and, accordingly, all modules are operated uniformly. A communication which, for example, also provides feedback of error information or the like is not provided in the illustrated embodiment, in which case, if appropriate, several of the contact fields 35 are used.

Another special feature is that - as shown in Figure 5 - two rows of contact pads 35 are provided, which are arranged with respect to a longitudinal axis 1 of the light module 20 rotated by 180 ° to each other. The reason for this measure is that this makes it possible to arrange the lighting module 20 optionally in different orientations, in particular in two orientations rotated by 180 ° on the carrier element 5. This may be of interest when the optical elements of the light emitting module 20 are formed so as to cause asymmetric light output to increase in a direction. In this case, it may possibly be provided that, for example, the lighting modules 20 arranged at the respective end regions of the carrier element 5 are aligned with respect to one another in a twisted manner, which in turn would cause a symmetrical light emission of the luminaire 1 as a whole. By arranging two similar, but rotated by 180 ° to each other arranged contact fields 35 can be made possible in a simple way a corresponding optional arrangement of the lighting modules 20, without these would have to be otherwise modified. As an alternative to the Federkon¬ clocks and contact surfaces shown, however, other system, in particular plug-socket systems could be used for electrical coupling.

Figures 7 and 8 show, as already mentioned, a sectional view of the luminaire 1, wherein initially in Figure 7, the light-emitting module 20 spaced from the support member 5 and arranged in Figure 8 is attached to the support member 5. In addition, the shape of the carrier element 5 can be taken from the representation of FIGS. 7 and 8, wherein it can be seen that it has two longitudinal side walls 12 extending above the U-shaped receiving region 6 for the lighting modules 20, which are narrower, towards the top form directed and turn U-shaped second receiving area 13, in which the lamp operating device 100 and possibly additional units 60 are arranged for the realization of Indi¬rect lighting, which will not be discussed in more detail below.

Furthermore, FIG. 9 shows, in an enlarged view, two adjacent lighting modules 20 latched to the support element 5, wherein it can be seen that both modules 20 together with their latching lugs 25 have the corresponding latching opening 9 in the bottom surface of the support element 5 use.

The present invention relates in particular to the arrangement and fastening of the end parts 15 on the end open carrier element 5, which will be explained in more detail below.

A single front part is shown here in isolation in Figure 11, wherein it has primarily a vertical wall 16, which is intended to complete the receiving area 6 of the Trägerele¬ments 5 frontally. Accordingly, the vertical wall 16 is matched to the dimensions of the receiving space 6 with respect to its height and width, and has lateral rounded edges, by means of which a correspondingly continuous transition to the side walls of the carrier element 5 is achieved.

The arrangement of the front part 15 on the carrier element 5 is initially carried out by means of zwei¬er tabs 17 which are provided on the upper side of the vertical wall 16 and aligned at right angles to the wall. These tabs 17 are inserted into corresponding recesses 11 of the support element 5, as can be seen in the illustration of Figure 10. The recesses 11, which form a guide for the tabs 17, can also be taken from the sectional views of Figures 7 and 8.

With the help of the tabs 17 so the front part 15 can then be pushed from the front side on the support member 5 and brought into the position shown in Figure 10. However, in this state, it is not yet fixed to the carrier element 5. To this end, additional holding means have been used, for example, special screw connections or derglei¬. Such additional holding means can be dispensed with according to the present invention, which is achieved by now using the lighting modules 20 themselves for locking the end pieces 15.

Namely, as can be seen in the illustration of Figure 11, on the guide plates 17 side facing the wall 16 of the front part additional locking means 18 are provided, via which a latching with the light module 20, more precisely with the locking tabs 25 of the light module 20 takes place. These latching means consist of a formed in the vertical wall 16 recess 19a and a recess spanning the bracket 19b. These elements are dimensioned such that the already mentioned before latching tabs 25 of the lighting modules 20 engage in this and can lock with them. The light modules 20 respectively arranged at the front ends of the carrier element 15 thus do not engage in recesses 9 of the carrier element 5 with their outer lugs 25, which are facing the front end, but instead interact with the latching means 18 of the respective front part 15.

In an assembly of the lamp 1, therefore, the end portions 15 are first as described be¬ written on the support member 5 is pushed. Subsequently, the lighting modules 20 are arranged on the carrier element and locked with this, in which case by the first and the last light module 20, the fixing of the end portions 15 takes place. There are then no weite¬ren measures more for additional support of the front part 15 is required because this is blocked by the associated light module 20 and can not be deducted.

Finally, therefore, by the measure according to the invention the assembly of the inventive lamp once again simplified and it can be dispensed with additional Befestigungs¬ means for locking the end caps. Of course, the erfin¬dungsgemäße solution is not limited to lights of the type shown. In principle, the idea of the invention can always be used when end pieces are to be arranged and fixed on a support element of a luminaire or a lighting arrangement, whereby at the same time exchangeable lamp units or luminaire modules are also provided on the support element. In all these cases, the fixing of the end parts can also be achieved by a special design of the exchangeable lighting modules, so that it is possible to dispense with additional working steps when fastening the end parts.
