    LUMINAIRE WITH BEARING ELEMENT AND SOLVENTLY LIGHTABLE MODULE
    The present invention relates to a luminaire, which has an elongated support member and at least one releasably attachable to the support element lighting module.
    The idea of interchangeably arranging lighting modules on a carrier element is known in particular from so-called continuous line lighting systems. These are illumination systems which have an elongated carrier element, for example a downwardly open U-shaped carrier rail, in or on the lines for the electrical power supply and optionally also for signal transmission. Depending on the Ausgestal¬tung the system then lighting modules can be arranged at certain predetermined positions or free at any point of the support rail. In this case, each lighting module special contacting elements - for example in the form of so-called rotary knob - on the one hand cause a mechanical attachment to the mounting rail and on the other hand also ensure a contacting of the lines. Furthermore, the lighting modules each have their own operating device which converts the mains supply voltage, which is made available via the power lines running along the mounting rail, into a suitable operating voltage for operating the light sources of the lighting module.
    A detachable arrangement of individual modules, which each contain light sources, would also make sense in individual luminaires, in particular if the light sources used are LEDs. Compared to conventional light sources such as incandescent bulbs or fluorescent lamps replacement of defective LEDs or defective LED boards is usually difficult for the end user to perform, so that in case of a corresponding defect either the lamp must be replaced or sent to the manufacturer or repair work must be performed by a trained electrician. This is due to the fact that for safety reasons usually LED boards must be installed in such a way that they are not readily accessible. One reason for this is that in this way the risk of electric shocks is excluded or at least reduced. Furthermore, an accidental touching an LED board to so-called ESD damage, so cause damage that are due to an unwanted elekt¬rische discharge. As a result, LED light sources in luminaires are usually arranged in a special shielded or encapsulated manner, and access to the circuit boards is often achieved only by destroying certain components which represent a corresponding protection.
    There are approaches to overcoming the above problems by providing the LEDs in special encapsulated modules that are releasably attached to the luminaire and electrically coupled to corresponding power supply means. In the event of a defect in the LEDs, it is then not the individual circuit board that is replaced individually but the cumbersome module, which as a rule can also be carried out relatively simply by the end user.
    However, in order to actually allow a simple exchange of individual modules by the end user in lights of the type described above, it must be ensured that when changing a lighting module or the first time arranging a light module to the support element reliably and safely the electrical connection is made to the operating device of the lamp. The object of the present invention is to offer a solution for this.
    The object is achieved by a luminaire, which has the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.
    Compared to previously known solutions in which primarily plug systems were used, it is proposed according to the present invention to produce the Stromversor¬ gene of the or to be connected lighting modules by means of contacts, which are formed according to the invention by spring contacts.
    According to the present invention, therefore, a lamp with an elongated Trä¬gerelement and at least one light module is proposed, which is releasably attachable to the support member. In this case, the lamp further comprises means for supplying power to the light module, which comprise contacts which are arranged on the carrier element or on a device carrier held by the carrier element, the contacts being formed by spring contacts.
    It has been found that the electrical connection between the operating device and the lighting module can be produced simply but very reliably by using the spring contacts. The replacement of a defective module by the end user is thereby simplified.
    According to a particularly preferred embodiment, the lighting module oneiner the support element facing bottom surface, which may be formed in particular by an LED board, mating contacts for cooperation with the spring contacts. Dabeikönnen these light module-side mating contacts may be formed in particular by applied to the bottom surface of the light module contacting fields. In this way, on the one hand the contacting is made possible in a very simple and reliable way, on the other hand, in this embodiment the lighting module has a flat rear side. This is not only advantageous in transporting the lighting module, as this can prevent damage to protruding elements such as plugs or sockets, for example, and a flat floor surface also ensures flat contact with the support element of the luminaire. This is relevant in that, during the operation of the light sources, a not insignificant amount of heat is generated, which due to the surface contact between the light module and the support element can be transmitted very efficiently and then released to the environment.
    Preferably, two groups of contacts, in particular two groups of the above-mentioned contacting fields are provided on the light module, which are arranged such that the light module can contact the carrier element side spring contacts in two positions rotated by 180 °. The reason for this measure is that in this case it is also possible to use light modules which cause an asymmetrical light emission, in which case these modules can then be arranged in different orientations on the carrier element. In the case of an elongated luminaire, it would be conceivable, for example, that light modules are used in the end regions of the carrier element, which give off increased light in a certain direction, in which case uniformly symmetrical light output is required, similar to the opposite end of the carrier element, So turn to use asymmetric lighting modules, however, are rotated rotated by 180 °. With the aid of the above-mentioned two groups of contacts, it is ensured that in both positions the lighting module can be efficiently coupled to the spring contacts, so that in each case a power supply is ensured.
    The spring contacts used according to the invention are preferably not arranged directly on the carrier element itself but on a device carrier held by the carrier element. This is arranged in particular on the side facing away from the light module of the support member, in which case pass through the spring contacts formed in the carrier element recesses. These measures ensure that further current-carrying elements can not be touched by the end-user-accessible side and, accordingly, that a single module can be changed easily and safely.
    Ultimately, therefore, it is ensured by the solution according to the invention that work to be carried out primarily by trained electricians can now be carried out simply but safely by the final consumer.
    The invention will be explained in more detail with reference to the accompanying drawings. FIG. 1 shows a luminaire according to the invention in a perspective view obliquely from above; Figure 2 is a side view of the lamp according to the invention; Figure 3 is an enlarged side view of the end portion of the lamp; Figure 4 is a view of the lamp according to the invention from below; FIG. 5 shows a lighting module to be fastened to the lamp in an exchangeable manner; Figure 6 is a sectional view of the lamp transversely to the longitudinal axis, wherein the interchangeable light module is arranged spaced apart from the carrier element; FIG. 7 is a sectional view corresponding to FIG. 6, wherein the luminous module is now fastened to the carrier element; FIG. 8 shows a perspective view of an end region of the carrier element of FIG
    FIG. 9 shows the view of the end region of a device carrier which, according to a preferred embodiment, is arranged on the carrier element and on which the spring contacts are arranged.
    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 support 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 releasably secured to the support member 5.
    FIG. 8 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 lighting modules - are arranged, one of which is shown in Figure 5 in a perspective view.
    The light-emitting module 20 is formed in the present embodiment, that is approximately cuboidal. As can be seen in particular from the sectional illustrations in FIGS. 6 and 7, the lighting module 20 consists of a cup-shaped, so-called lens carrier 21 formed of at least partially transparent material, which has a bottom surface 22, which forms the light emitting surface of the lighting module 20, and four side walls 23, 24aufweist. At the two shorter side walls 24 in each case two locking tabs 25 are formed, via which a fastening to the carrier element 5 of the lamp 1 takes place. As can be seen from the illustration of FIG. 8, corresponding recesses or slots 9 are formed in the bottom surface 7 of the receiving region 6 of the carrier element 5, into 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 6). 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 6, 21 Linsen body 26 are formed in the central region of the lens carrier, which are each associated with individual LEDs 31. On the other hand, the light of the LEDs 31a located in the edge region should not be emitted with the aid of lenses, but rather cause a diffused luminous 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 a plurality of the light modules 20 be attached to the support element 5 of the luminaire 1 so that an appearance results from the underside or the light emission side, as shown in FIG.
    The rear side of the light module 20 forming LED board 30 is latched 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 20verfolgt using special contacting means comprising spring contacts 41 according to the present invention, which cooperate with arranged on the back of the LED board 30 Kontakt¬felder 35. The spring contacts 41, which are connected to the operating device of the luminaire 1 in a manner which will be described in more detail later, are each connected here at one of e.g. arranged in Figure 6 recognizable contact block 40 which projects through a corresponding recess 10 in the bottom surface 7 of the receiving portion 6 of the support member 5. This means that 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 lighting module 20 when the lighting module 20 is inserted. As a result, the electrical connection between the Federkon¬ clocks 41 and the light emitting module 20 and thus ultimately the power supply of the Leuchtmo¬duls 20 is ensured.
    As can be seen from the illustration of Figure 5, a plurality of contact pads 35 are formed on the back of the LED board 30, wherein not necessarily all contact fields 35 must be used depending on the mode of the lamp 1. 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 20 are operated uniformly. A communication that would also allow, for example, the feedback of Fehler¬ information or the like, is not provided in the illustrated embodiment, in which case, if appropriate, more of the contact pads 35 are used and accordingly more spring contacts 41 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 light module 20 selectively 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 providing two similar, but rotated by 180 ° to each other arranged contact field groups can be made possible in a simple way a corresponding optional arrangement of the lighting modules 20, without these would have to be modified otherwise.
    Figures 6 and 7 show, as already mentioned, a sectional view of the luminaire 1, wherein initially in Figure 6, the light module 20 spaced from the support member 5 and arranged in Figure 7 is attached to the support member 5. In addition, the shape of the carrier element 5 can be seen from the representation of FIGS. 6 and 7, wherein it can be seen that this 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.
    Preferably, the contact blocks 40 with the spring contacts 41 are not directly on the carrier element 5 but instead arranged on a so-called. Equipment carrier 50, which is shown in Figure 9. This is formed by an elongated sheet metal part and serves as a central holding element for the components for powering the lighting modules 20. The contact blocks 40 with the spring contacts 41 are again not directly disposed on the Geräteträger50 but instead mounted on so-called connection boards 45. These connection boards 45, one of which is shown in FIG. 9, each have two contact blocks 40 with spring contacts 41, so that they are ultimately designed to make contact with two light modules 20.
    The arrangement of the connection boards 45 to the equipment carrier 50 is again preferably without tools, which is achieved in that the boards 45 have at their longitudinal sides elongated projections 46. These are intended to be connected to the implement carrier 50 in the sense of a bayonet lock. For this purpose, the device carrier 50, which is curved in a C-shaped cross-section, has two elongated side walls 51, on each of which recesses 52 are formed, which open into undercuts 53. The connection board 45 is then placed from the top side (as shown in FIG. 9) such that the supernatants 46 engage in the recesses 52. Subsequently, the board 45 is displaced in the direction of the arrow relative to the device carrier 50, so that the projections 46 engage in the undercuts 53. As a result, the circuit board 45 is securely latched to the device carrier 50, without the need for a tool or additional connecting means. Andem equipment carrier 50 are then arranged a plurality of corresponding Verbindungs¬platinen 45 in this way, so in the present case, half as many boards 45 are required as lighting modules 20 are to be attached to the support member 5 of the lamp 1.
    In addition, a plug 44 or a terminal is arranged on each connection board 45, which is connected to the contact blocks 40 via printed conductors, which are not shown in more detail. The plug 44 is located on the side opposite the contact blocks 40 of the board 45 and is connected to the operating device 100 - which is also arranged on the device carrier 50 - via cables. In this way, therefore, the electrical connection between operating device 100 and contact blocks 40 is ensured.
    The preassembled unit of the device carrier 50 with the Betriebs¬gerät 100 located thereon and the connecting boards 45 is then inserted from the top into the Trä¬gerelement 5 and locked with this, so that ultimately the illustrated in Figures 6 and 7 Configuration results. As already mentioned, in this case the individual components are arranged such that the contact blocks 40 with the spring elements 41 protrude through the openings 10 of the carrier element 5, while all other current-carrying elements are inaccessible from the underside from which the lighting modules 20 are mounted or removed ¬ are.
    The solution according to the invention thus permits a simple production of the electrical connection and thus the power supply of the exchangeable lighting modules. The illustrated preferred embodiment is furthermore distinguished by the fact that the luminous modules have a flat rear side and can thus lie flat against the carrier element, which also represents a clear advantage with regard to efficient dissipation of heat arising during operation of the luminaire.
