    Luminaire with contacting module
    The present invention relates to a lamp with a device carrier, which carries on one side of a circuit board, which is electrically contacted.
    Luminaires with linear device carriers are in particular also widely used for the formation of light bands in the prior art. Such luminaires, which are produced in large numbers, are preferably to be designed so that they can be produced fully automatically. In particular, the wiring and their contacting is problematic because it can not be easily made by a robot.
    An example of an electrical coupling system for lighting units of the type mentioned is known from DE 197 46 493 CI. For power supply of mounting rail lights a connection and coupling system is provided, can be connected to the light source on the mounting rails with the electrical supply line. The coupling system comprises a plug and a corresponding socket which is arranged on the mounting rail. However, the electrical coupling systems often have the disadvantage that they are only applicable to a particular type of mounting rail light. Furthermore, although the coupling systems are easily connected to each other, but the electrical contacting of the systems requires some manual work.
    Object of the present invention is to provide a luminaire of the type mentioned with a KontaktierungsSystem, which can be easily, in particular fully automatic, mounted on the lamp and is applicable to a variety of different lights.
    The problem is solved by a luminaire according to claim 1.
    The luminaire according to the invention comprises a device carrier, which in particular is elongate, e.g. is designed as a continuous profile, in particular as an aluminum profile. The profile carries a circuit board on one side. In particular, the printed circuit board can be set up to carry or to be connected to electric lighting means, in particular LEDs (which are also to be understood as OLEDs). The board is from the opposite side of the
    Device carrier electrically contacted. For example, the board can be arranged on the downwardly facing side of the device carrier directly in the direction of radiation of the lamp, while the electrical contact is made from the side of the ceiling. For electrical contacting a contacting system is provided, which is formed of at least two modules which are inserted into each other. For this purpose, an opening in the equipment carrier is provided, through which the modules interlock. The modules inserted into each other engage through the opening in the equipment carrier from the side of the board to the opposite side. To attach the modules is provided that the modules are clamped at the periphery of the opening in the equipment rack. Preferably different wall thicknesses different equipment carriers can be provided with the same contacting system, because the modules of the contacting system are designed so that they can reach through different wall thicknesses of the equipment carrier and can be clamped to this. In the contacting system, at least one electrical conductor is provided, which provides the electrical connection from the board to the opposite side of the equipment carrier.
    The contacting system of the present invention directly accesses the board. A separate wiring, such as by soldering individual electrical lines to the board, can therefore be omitted, whereby the production is much easier. This feature is particularly advantageous for lights with LEDs as bulbs, because the LEDs are mounted directly on boards and are connected to electrical traces on the board. In contrast to conventional bulbs, whose leases anyway require separate wiring, in the case of LED lights, the contacting system can provide the electrical supply in the luminaire directly via the circuit board on which the LEDs are mounted.
    According to a preferred embodiment, the two modules of the contacting system have mutually cooperating locking means by which the modules are held against the direction in which they have been put together, so that they clamp on the opening. A latching connection is suitable for the contacting system, because on the one hand it can be easily connected to one another, in particular is suitable for robots, and on the other hand it can also be loosened again, in contrast to adhesions or riveted joints.
    According to a preferred development several locking teeth are provided in succession in the plugging direction of the modules, so that the modules are latched to each other at different distances to include different wall thicknesses of the equipment carrier in the region of the opening. In this embodiment, the same modules of the contacting system can be used for different device carriers, which differ in the wall thickness in the region of the opening, through which the modules of the contacting system, reach through. The spacing of the ratchet teeth is preferably very small, e.g. Less than 1 mm, so that when assembling the modules to the stop on the opposite side of the opening in the equipment rack a clamping on the equipment rack can be done without play.
    According to a preferred embodiment, the at least one electrical conductor in the contacting system is formed by a metallic spring element. The spring element has the advantage that it can compensate for different distances between the modules. Furthermore, the spring element can be elastically brought into contact with the adjacent electrical components, in particular the circuit board. For example, a spring tongue is provided on the spring element, which acts on the board to form an electrical contact between the spring element and the board. In the area between the board and the opposite side of the device carrier, the spring element can have an elastic compression region or it is inserted into one another in two parts, so that in each case the electrical connection can be formed from the first to the second module at different distances between the modules.
    According to a preferred embodiment, the electrical contacting system comprises two or more electrical conductors, so that a supply voltage and a neutral can be applied to the board. Preferably, more than two electrical conductors are provided to connect control lines on the board can. For example, the electrical conductors can be realized by a plurality of spring elements, which are provided parallel to each other, in the contacting system.
    According to a preferred embodiment, the contacting system on the side opposite the board on a plastically deformable region, in particular in the form of a sleeve, on which an electrical cable can be mechanically held by clamping force and thereby an electrical contact to the electrical conductor in the Kontaktie insurance system is formed. This type of connection of an electrical line can be performed automatically in a fully automatic machine with a corresponding crimping tool. In particular, no soldering or screwing the electrical connection line is necessary for contacting the KontaktierungsSystems.
    Further eliminates the need to provide a lead for the contact system a plug-in contact, which is plugged into the contacting module. This can save material costs.
    According to a preferred embodiment, the contacting system has a width transverse to the longitudinal extension of the device carrier, which extends across the width of the board in the same cross-section. This allows the module to completely overlap the board to connect several parallel tracks on the board, each with an electrical conductor of the contacting system. There is therefore no need for a plurality of electrical contacts, the need to provide several contacting systems in a row for a board in the lamp. All it takes is a wide contacting system which accesses a large number of parallel conductors on the board.
    According to a preferred embodiment, the at least one electrical conductor of the contacting system is on the side of the device carrier with the board and / or on the opposite side to the outside, i. downwards or upwards, each covered by a wall of the relevant module. As a result, a contact protection of the electrical conductor is given. Preferably, the wall is designed so that a penetration of the contacting system with a screwdriver or other tool of comparable width is prevented. This protection is often required for luminaires to ensure the safety of a fitter, even when working on live luminaires with metallic tools. The contacting system of the present invention makes it possible by simple means, i. In particular, without a separate cap or the like. To ensure a contactor against the electrical conductor in the contacting system.
    According to a preferred embodiment, which is particularly advantageous for lights with an elongated equipment carrier and an elongated board, the lamp has two contacting systems, which are preferably vorgese at opposite ends of the board hen. The contacting systems can serve in this embodiment to mechanically hold the board to the equipment carrier. In this embodiment, only one of the two contacting systems need to have an electrical conductor, because the second contacting system can only serve the mechanical support of the board.
    Other features and advantages of the present invention will become apparent from the following description of a preferred embodiment described in conjunction with the accompanying drawings. The figures show the following:
    Figure 1 shows a perspective view of a section of a moisture with a
    Contacting system, which is shown prior to assembly and without electrical Feiter in the contacting system.
    Figure 2 shows a perspective view of a cross section of the moisture of Figure 1 in the assembled state with electrical conductor.
    Figure 3 shows the humidity of Figure 1 and 2 in a perspective view of the side of the board.
    Figure 4 shows a plan view of a cross section of the moisture according to Figures 1 to 3 in a partially sectioned view.
    A luminaire of the illustrated embodiment comprises an elongate device carrier 2, which is formed as a continuous extruded profile. On the device carrier is on the underside of the device carrier (see Figure 3, which represents the underside in the plan view), a board 4 is provided on the mounted in a row a plurality of LEDs 6 and are electrically contacted.
    To connect the board 4 to electrical supply lines, which are guided on the circuit board opposite side of the device carrier 2 to the light (not shown in the figures), a formed of two modules 10, 12 contacting system is provided which extends through an opening 8 in extend the device carrier 2. The module 10, which is passed from the side of the board 4 through the opening 8 of the device carrier 2, extends across the width of the board 4 and has, in the embodiment shown, two electrical conductors 20 in the form of spring elements which make electrical contact with enter the board 4 (see Figure 3). On the opposite side of the device carrier 2, the second module 12 of the contacting system is attached to the board-side module 10 (see FIG. 1). For this purpose, a plurality of locking teeth 14 are provided on the board-side module 10 on two sides in the longitudinal direction of the lamp, which cooperate with provided on two inner sides of the module 12 ratchet teeth 16. The ratchet teeth 14 and 16 on the two modules each comprise a sequence of several parallel ratchet teeth in the direction of insertion of the two modules 10 and 12. This makes it possible to lock the modules at different distances from each other. In order to fix the contacting system to the equipment carrier 2, the upper module 12 is plugged onto the board-side module 10 until a flange-like projection 18 of the module 12 rests on an edge region of the opening 8 in the equipment carrier 12 and thereby the two modules by clamping on the equipment carrier holds. The plurality of ratchet teeth 14 and 16 on the modules are provided to accommodate different wall thicknesses (including any hollow areas) of the device carrier can. In this way, the same contacting system can be provided flexibly on different device carriers or at different thicknesses of the device carrier in openings 8.
    Inside the contacting system (see Figures 2 and 4), an electrical conductor 20 is provided in the form of a spring element. In the lower region on the board 4, the electrical conductor 20 comprises a spring tongue 22, which establishes the electrical contact with the board 4. In the middle region of the electrical conductor 20, a compression region can be provided, which can provide different lengths of the electrical connection by elastically compressing between the modules to different degrees. It is preferably provided that the electrical connection is formed from two elements which are pushed into each other in the area between the modules in different insertion depth or pushed over each other.
    In Figures 2 and 4 it is shown that an angled electrical portion 24 is slid over a portion of the electrical conductor of the opposite module to provide a continuous electrical connection.
    The module 10 on the circuit board 4 opposite side of the equipment carrier 2 further comprises a sleeve 26 in the form of a cylindrical portion which has an entrance opening in the
    Housing of the module 10 forms. The sleeve 26 is plastically deformable so that one or more cables can be inserted through the sleeve and held by squeezing the sleeve against the module. This type of contacting can be done in particular by an automatic robot with a corresponding crimping tool. The electrical supply cable is brought into contact with the electrical connection 20 in the upper region of the module 12 in order to allow the electrical supply of the LEDs on the board on the opposite side of the device carrier. Alternatively, a metallic clamp is provided in the sleeve into which a wire can be inserted and held therein by clamping force to provide the electrical connection.
    The modules 10 and 12 of the contacting system have on the outside walls 28 and 30, which cover the electrical conductors 20 inside the modules up and down. The walls are designed so that in the mounted state of the modules, the electrical conductors 20 are completely covered, so that any gaps have only one size, which prevent penetration by a sharp object, such as a screwdriver. This prevents the risk of accidents if improper work on the luminaire is carried out in the live state of the luminaire.
    Numerous modifications of the preferred embodiment described above are possible within the scope of the invention without departing from the scope of the invention, which is defined by the claims. In particular, more or fewer than two electrical conductors may be provided within the contacting system. It may be provided a whole number of four or more parallel elements to connect not only two electrical supply lines but also a number of control lines to the board. Accordingly, more than just two of the sleeves 26 may be provided.
    The device carrier 2 can take different forms and the openings 8 in the equipment carrier 3 can be arranged differently. For example, the openings may extend only over a portion of the width of the board 4, to access only a portion of the board. It can be provided successively staggered contacting systems, each to access a portion of the board. However, a contacting system for the entire board is preferred. In the case of an elongate printed circuit board, two contacting systems can also be provided at opposite ends of the printed circuit board in order to hold the printed circuit board mechanically to the equipment carrier. An electrical conductor only needs to be present in one of the two contacting systems.
    Although different bulbs can be electrically supplied with the previously described contacting system, LEDs are preferred because LEDs are anyway mounted on a circuit board, so that a separate wiring to illuminant holders according to the invention can be completely eliminated.
