    LUMINAIRE WITH INTERCHANGEABLE ILLUMINATED MODULES
    The present invention relates to a luminaire, which has an elongated support member to which a plurality of lighting modules are releasably attachable.
    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 because, for safety reasons, LED boards are generally installed in luminaires in such a way that they are not easily accessible. One reason for this is that in this way the risk of electric shock is eliminated or at least reduced. Further, accidental touching of an LED board may cause additional ESD damage, that is, damage due to unwanted electrical discharge. As a result, LED light sources in luminaires are usually arranged in a special shielded or encapsulated manner, and access to the boards is often achieved only by destroying certain components that provide adequate 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.
    The present invention is based on the object to simplify the structure for a lamp of the type described above with interchangeable lighting modules whose construction.In particular, an assembly of the lamp is to be facilitated in terms of the means for Stromversor¬gung the lighting modules.
    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.
    The luminaire according to the invention has, as described above, an elongate carrier element on which a plurality of lighting modules can be detachably fastened. Furthermore, means for the power supply of the lighting modules are provided, these means comprising an operating device and connected to the operating device contacting means to which the lighting modules are electrically connected. In this case, the operating device and the contacting means are arranged according to the invention on a device carrier, which can preferably be attached as a preassembled unit to the carrier element of the luminaire.
    By the solution according to the invention, the production of the light relationship or the other assembly is significantly simplified. Since all the essential components for the electrical power supply of the exchangeable lighting modules are arranged on the equipment carrier, it can first be fitted with the corresponding components in a simple manner. Subsequently, only the placement of the device carrier on the support element of the lamp is required. A complex laying of individual cables to provide the individu¬ellen power supply for the individual lighting modules, however, eliminated, so that the light overall seen a very clear structure. Maintenance or repair work, which concern the means for powering the lighting modules, this also facilitated.
    The equipment carrier is arranged according to a preferred embodiment of the invention on the side facing away from the light modules side of the support member, wherein the Kontak¬tierungsmittel then pass through recesses formed in the support member. The light modules are thus fastened to the carrier element from the underside or the light emission side, while the device carrier is arranged on the carrier element from the opposite side and is preferably snapped or latched thereto. This measure also contributes to the improvement of possible maintenance work by the end user, since when exchanging individual defective light modules from the light emission side with the exception of the contact means all weite¬ren means for power supply are protected and there is no risk that they are unintentionally touched.
    The contacting means are preferably not directly on the equipment carrier, which is itself formed by a correspondingly shaped sheet metal part, arranged, but instead -des on so-called interconnection boards. These are in turn detachably fastened to the device carrier and on the one hand have the contacting means and, on the other hand, means for electrical connection to the operating device of the luminaire. These means for electrical connection may be a simple plug or a clamp, about denbzw. then followed with the aid of a corresponding cable connection to the operating device. The contacting means for producing the electrical connection to the corresponding luminous module are then connected to the plug or the terminal, for example via printed conductors formed on the connecting plate.
    Preferably, several Kontaktierungsmit¬tel, for example, two contacting means are arranged on each of the interconnection boards. These contacting means may be, for example, plugs or sockets of an electrical connector system which then interact with a suitable counterpart located on the light module. However, the contacting means are particularly preferably formed by simple contact elements, in particular by spring contacts. When arranging a lighting module on the support element of the luminaire, these come into contact with contacts located on the luminous module and ensure the electrical supply of the luminous module.
    In turn, according to the preferred embodiment of the invention described above, a plurality of the interconnecting boards are disposed on the elongate apparatus carrier, each of the interconnecting boards then being connected to the operating device via cables. In particular, a suitably designed cable harness is used, which is coupled on the one hand to the operating device and, on the other hand, to the various connecting boards. The individual lines of the wiring harness have a different length and in particular are dimensioned such that their length corresponds approximately to the distance between the connection board or the plug / terminal of the Ver¬bindungsplatine and the operating device. That is, the harness has specifically in terms of their length to the position of the circuit board to be supplied cable, so that a very clear cable management is guaranteed. This can also be further optimized or improved by the cables are led to the connecting plate to be connected in a space between the connection boards and the equipment carrier.
    Ultimately, therefore, created by the inventive solution a very clear modulatory structure for the lamp, are significantly simplified by the repair or maintenance work. The construction according to the invention also makes it possible to provide luminaires of different dimensions and with correspondingly different numbers of exchangeable lighting modules in a simple manner.
    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; FIG. 6 shows a perspective view of an end region of the carrier element of the luminaire; Figure 7 is a sectional view of the lamp transversely to the longitudinal axis, wherein the interchangeable light module is arranged spaced from the Trägerele¬ment; Figure 8 is a sectional view corresponding to Figure 7, wherein now the
    Lighting module is attached to the support element; Figures 9 and 10 are views of the end portion of the device carrier according to the invention; Figure 11 is a perspective view of the complete equipment carrier and Figure 12 is an enlarged sectional view to illustrate the detachable
    Attachment of the device carrier to the support element of the lamp.
    Figures 1 and 2 show different views of the generally provided with the reference numeral 1 invention 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 to 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. 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 on both sides of Bodenfläche7 extending downwardly directed U-leg 8. 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 engage in a latching manner.
    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, wherein the LEDs 31 may be associated with different optical means for influencing the light output.
    As can be seen in Figure 7, 21 lens body 26 are formed in the illustrated embodiment in the central region of the lens carrier, which are each associated with individual LEDs 31. On the other hand, the light of the peripheral LEDs 31a should not be directed by means of lenses, but rather cause a rather diffused luminous surrounding frame. This is achieved by a special diffuser frame 35, which is inserted into the lens carrier 21 and, compared to the lens carrier 21, which preferably consists of a clear material, consists of a light-scattering material or contains light-scattering particles. It should be noted, however, that of course the design of the optical elements of the individual lighting modules 20 could also be designed differently, if another type of light emission is desired. The design of these optical elements is not further for the core idea of the present invention relevant. However, it is essential that several of the lighting modules 20 are fastened to the carrier element 5 of the luminaire 1, so that an appearance results from the underside or the light emission side of the luminaire 1, as shown in FIG. 4.
    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 it can be easily placed on the open lens carrier 21 from the rear side and then pressed down. In this way, a stable assembly is formed, which in turn effectively protects the individual LEDs 31 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 when the lighting module 20 is inserted into the receiving region 6, they come into abutment against the contact fields 35 of the lighting module 20. As a result, the electrical connection between the spring contacts 41 and the lighting module 20 is ensured, so that the latter - as described in more detail below - 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. This depends, inter alia, on whether only a simple switching on and off of the modules 20 is provided or whether these should enable individual controllability. In the illustrated embodiment, only two spring contacts 41 are used so that the modules 20 are therefore supplied exclusively with a suitable supply voltage or supply current and, accordingly, all the modules are operated uniformly. A communication that would, for example, also enable the feedback of error information or the like, is not provided in the illustrated exemplary embodiment, in which case optionally several of the contact fields 35 are used for this case.
    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 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.
    It should be noted that instead of the illustrated spring contacts and thus zusammenwir¬kenden contact fields and plug systems could be used to connect the lighting modules.
    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 seen from the representation of FIGS. 7 and 8, wherein it can be seen that this has two longitudinal side walls 12 extending in the longitudinal direction above the U-shaped receiving region 6, which has a narrower, upward direction directed and in turn U-shaped second receiving area 13 form.
    These side walls 12 are also well recognizable in the illustrations of Figures 1 to 3, wherein it is further apparent that the walls 12 do not have the same height over the entire length of the lamp 1hinweg. In particular, seen in the longitudinal direction, a slightly raised receiving space 13a is formed in the middle region of the luminaire 1, which serves to receive the operating device 100 of the luminaire 1, by means of which the external supply voltage is converted into a suitable operating voltage or operating current for the luminous modules 20. Furthermore, in this middle receiving space 13a above the operating device 100, a lighting unit 60 is provided for generating an indirect lighting. On both sides of this raised middle region 13a, slightly lower receiving areas 13b are formed, which can likewise serve to accommodate further lighting units for producing an indirect illumination, which, however, will not be explained in detail in the present case.
    Instead, the present invention deals with special measures by means of which the electrical connection between the operating device 100 and the spring contacts 41, via which the contacting of the lighting modules 20 ultimately takes place, is ensured.
    9 and 10 show representations of a so-called device carrier 50, which is formed by an elongated sheet metal part and serves as a central holding element for the components for the power supply of the lighting modules 20. The device carrier 50 thus serves, in particular, to hold the contact blocks 40 with the spring contacts 41, although they are not arranged directly on the device carrier 50, but instead are mounted on so-called connecting plates 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 for contacting by two lighting modules 20.
    The arrangement of the connection boards 45 on 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 projections 46 engage in the recesses 52. Subsequently, the board 45 is displaced in the direction of the arrow with respect to the device carrier 50, so that the projections 46 engage in the undercuts 53. As a result, the board 45 is securely mounted on the device carrier 50, without requiring a tool or additional connecting means would be required. On the equipment carrier 50 a plurality of corresponding Ver¬bindungsplatinen 45 are then arranged in this way, so in the present case, half as many boards 45 are neces- sary as lighting modules 20 are to be attached to the support member 5 of the lamp 1.
    On each interconnect board 45 is also a plug 44 - the use of a terminal would be conceivable - arranged, which is connected via Lei¬terbahnen not shown with the contact blocks 40. The plug 44 is located on the side of the board 45 opposite the contact blocks 40 and is connected to the operating device 100 via cables. In this way, therefore, the electrical connection between the operating device 100 and contact blocks 40 is ensured.
    FIG. 11 shows an entire device carrier 50 with the connection boards 45 arranged on the underside and the operating device 100 arranged on the opposite side. On the side of the operating device 100, a terminal 101 is also arranged, via which the connection with the external power supply lines takes place.
    As already mentioned, the connection between the operating device 100 and the connecting boards 45 via cables, preferably using a wiring harness is used, the lines having, on the one hand to the operating device 100 and on the other hand with the connecting boards 45, more precisely with the plugs 44 of Verbindungsplatinen45 are connected. The cables of the - not shown - harness are matched in terms of their length to the distance between the operating device 100 and the connection boards 45, so that no loosely extending cable loops remain. Instead, the cables are preferably routed in the intermediate region between the bottom surface 55 of the device carrier 50 and interconnecting board 45, so that ultimately a tidy assembly as shown in Figure 11 is obtained. This contains all the essential components for the power supply of the lighting modules 20 and can then be attached in a simple manner to the support element 5 of the lamp 1.
    The attachment of the device carrier 50 is again preferably without tools, in which case in particular a locking is provided. This is achieved by the fact that on the side walls 51 of the device carrier 50 bulged nubs 56 are formed, as they are clearly visible in particular in Figure 10. With the help of these nubs 56 of the device carrier 50 is then locked to the support element 5 of the lamp 1. This is done by the fact that the
    Device carrier 50 is inserted from the top into the open upper receiving portion 13 of Trä¬gerelements 5 and pressed towards the bottom until the bulged nubs56 corresponding inwardly projecting projections 15 of the aluminum profile, which forms the Trä¬gerelement 5, engage behind. By means of a guide lug 57, which is formed on an end face of the device carrier 50 and engages in a recess in the equipment carrier 5, it is ensured that the equipment carrier 50 is correctly positioned and oriented in the carrier element 5 is inserted.
    The locking can be very well taken from the enlarged view of Figure 12, which shows the arrangement of the device carrier 50 in the support member 5. Visible here is also the intermediate space between the bottom surface 55 of the device carrier and the connecting plate 45, which can be used for guiding the - not shown - lines of the wiring harness and in which the plug or terminals 44 are located. Furthermore, it is identifiable in which way the contact blocks 40 with the spring contacts 41 reach through the recesses 10 in the bottom surface 6 of the lower receiving region such that they are accessible to the contacting fields 35 of the lighting modules 20.
    Ultimately, therefore, a very modular design for the lamp is achieved in total by the special design of Gerä¬teträgers invention. The individual components can be mounted as prefabricated structural units very simply and quickly on the support element of the luminaire and in particular also fastened without tools, so that on the one hand the assembly of the luminaire is facilitated, but in particular also maintenance work can be carried out very easily.
