    LIGHTING MODULE AND LIGHT WITH SEVERAL LIGHTING MODULES
    The present invention relates to a lighting module, which is adapted to be interchangeable attached to a support member of a lamp. Furthermore, the present invention relates to a lamp with at least one corresponding replaceable lamp module.
    LEDs have prevailed due to advances in the development of such light sources in the past not only in special applications but in all fields of lighting technology. In particular, LEDs can be used in the meantime readily for general lighting and have replaced in this regard classical light sources such as fluorescent lamps or light bulbs. Advantages of LED-based light sources lie in a better controllability of such light sources and the usually significantly longer life. These advantages compensate for the currently still existing disadvantage of higher production costs.
    Despite all, even with lights in which LEDs are used as light sources, a change of light sources may be required due to a defect or other signs of aging. A change of a corresponding lamp module would also be useful if, for example, light sources to be replaced in terms of their color to adjust the appearance or Lichtabstrahlcharakteristik the lamp.
    In this case, however, there is the problem that LEDs in contrast to fluorescent lamps or light bulbs can not be used in a simple manner in appropriate versions and removed again but the change of LED boards is usually associated with a greater effort. This is also due to the fact that within lights usually the LED light sources must be arranged in a special protected manner. One reason for this is that the LEDs should be protected against so-called ESD damage, ie damage due to electrostatic discharge. Furthermore, it has been found that an efficient LED operation can be achieved, especially at voltages in the high-voltage range, ie at about 220V. Accordingly, voltages are present at the LED boards in these cases, which can lead to an electric shock in case of accidental contact, which may well be harmful to health. The change of LED light sources in such lights was therefore previously mainly feasible only by appropriate personnel.
    The present invention is therefore the task of specifying a novel solution that allows a simple and reliable fastening a Leuchtmit tel module to a support element of a lamp. In particular, the solution should open the possibility to be able to replace appropriate lighting modules easily and quickly when needed.
    The object is achieved by a light-emitting module having the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.
    According to the invention it is provided that one or more specially designed so-called snap-connection elements are provided on the lamp module. These snap connection elements are designed such that they allow a releasable attachment to the support element of the lamp, wherein the connection to the support element in particular without tools, so for example by simple locking takes place. For this purpose, the snap connection elements according to the invention each have a correspondingly formed latching area, which cooperates with a corresponding latching opening in the carrier element of the luminaire.
    [0008] According to the present invention, a light-emitting module for releasably connecting
    Ordered on a support element of a luminaire, wherein the lamp module has one or more snap-in connection elements, which each have a latching area which is designed for latching with the carrier element of the luminaire.
    The solution according to the invention thus makes it possible to attach light-emitting modules very easily and quickly, in particular without tools on a support element of a lamp. Even a later change of a module, for example, because this is defective or the Lichtab-beam characteristic of the lamp to be changed, is easy to perform.
    The snap connection elements according to the invention are in this case preferably designed such that they can also be connected without tools to be fastened with the light bulb module, in particular can be locked with this. For this purpose, the snap connection elements preferably have a second latching area opposite the first latching area. In contrast to the first latching region, which is provided for connection to the carrier element of the luminaire, however, this second latching region is preferably designed in such a way that the connection to the luminous means module can no longer be readily released. The two latching areas are thus preferably designed differently, so that it is ensured that the snap connection element remains permanently on the lamp module.
    A particularly preferred embodiment is obtained when the snap connection element is attached to a circuit board of the lamp module and the board is to be coupled simultaneously with a flat heat sink. Such a structure is particularly necessary if over the surface of the board alone, the heat occurring during operation of the lamps, so in particular the LEDs heat can not be sufficiently dissipated. In this case, a sandwich structure is then usually used, in which a heat sink, that is to say, for example, a metal plate or the like corresponding in terms of its dimensions of the LED board, is arranged flat on the rear side of the board. So far, it has been customary in this case to couple the circuit board and heat sink by means of separate connection elements, in particular by means of screw connections.
    According to a particularly preferred embodiment of the present invention, however, can be dispensed with such additional measures, since the snap connection elements at the same time a coupling between the heat sink and the illuminant carrier, so LED board cause. In this case, the latching areas of the snap connection elements pass through both a corresponding recess in the heat sink and in the illuminant carrier and clamp both elements between the corresponding latching area and a planar contact area such that a reliable connection and thus thermal coupling between the two elements is achieved. In this variant, therefore, the snap connection elements according to the invention fulfill an additional function, so that the number of components required on the one hand for mounting the lamp module and on the other hand for realizing the detachable connection to the support element of the lamp is reduced.
    The snap connection elements according to the invention are preferably plastic parts, which are produced in particular by injection molding.
    The invention will be explained in more detail with reference to the accompanying drawings. 1 shows a perspective view of a luminaire, in which several illuminant
    Modules are to be releasably secured by means of the inventive solution; Figure 2 is a view of a lamp to be fastened on the lamp module; Figure 3 shows the view of a snap connection element according to the invention and Figure 4 is a sectional view of a fastened using the invention Schnappver connecting elements on the support element of the lamp Leuchtmit tel module.
    Figure 1 shows a perspective view of a generally provided with the reference numeral 100 luminaire, in which the solution according to the invention is to be used. However, the realization of the releasable holder according to the invention with the help of the snap connection elements described in more detail below is not limited to the corresponding illustrated special light, but can always be used when lighting medium modules - in particular with LED-based light sources - detachable on a Carrier element of a luminaire to be attached. The luminaire 100 shown in FIG. 1 is an elongate luminaire, which in the case shown is designed as a pendant luminaire, that is to be attached by means of two cables 101 or rods to a support element (not shown).
    The central element of the lamp 100 according to the invention is an elongated support member 110, which is formed by a corresponding aluminum profile body. This carrier element 110 serves to hold all the essential components of the luminaire 100, in particular the illuminant or LED modules described in more detail below, as well as corresponding operating devices for operating the LEDs. While the LED modules are to be fastened to the carrier element 110 from the underside, in particular in a receiving area which is approximately C-shaped in cross-section and open toward the underside, the operating devices (not shown) are preferably at the rear or top side of the carrier element 110 arranged. On the upper side of the carrier element 110, additional light sources (not shown here) can additionally be arranged, with the aid of which an indirect illumination can be realized.
    FIG. 2 shows a perspective view of an LED module 50, as is preferably used in the luminaire according to FIG. The LED module 50 is configured roughly parallelepiped-shaped and is intended to be attached to the carrier element 110 from below and fastened there. As can be seen, the LED module 50 in this case is significantly shorter than the carrier element 110. Although it preferably has about a comparable width, however, extends in the longitudinal direction of the lamp 100 only over a fraction of the support member 110 away. For example, in the case of the luminaire 100 of FIG. 1, about ten or fourteen such LED modules 15 are arranged in succession. Also in this regard, however, the invention is by no means limited to such a specific embodiment. For example, with the aid of the solution according to the invention, a single LED module, which is the only light source of a luminaire, could be exchangeably fastened to a corresponding carrier.
    As already mentioned, the LED module 50 is approximately cuboid. Its rear or bottom surface 51 is in this case formed by a board and a flat heat sink, which is thermally coupled to the board and causes an improved dissipation of the heat occurring during operation. Alternatively, the LED board could directly form the back 51 of the module 50.
    Depending on the manner in which the light output of the module 50 is to take place, the LEDs are arranged in a matrix-like or otherwise distributed manner on the circuit board 51. A preferably completely made of a transparent material, such as cup-shaped cover 60 forms here together with the board 51, a housing. In particular, the bottom surface 51 and cover 60 surround a cavity in the interior of the module 50 in which the LEDs are arranged on the one hand and on the other hand, additional optical elements for influencing the light output can be arranged. For example, the arrangement of a lens arrangement or a grid would be conceivable. It is essential that the cover 60 at the same time provides protection for the LEDs arranged in the interior, since it is not readily detachable from the bottom side 51 and accordingly accidental contact with the LEDs can be excluded in this way. On the back of the module 50 may further be provided, not shown, electrical contacting element, via which the power supply of the LEDs takes place. This must be coupled with a corresponding counterpart of the lamp 100 to ensure the power supply of the LEDs.
    The desired releasable fastening of the lamp module 50 to the support member 110 is achieved according to the invention by means of two snap-in connection elements 10, which are shown in Figure 2 in a fastened to the lamp module 50 state. On the other hand, FIG. 3 shows in isolation an inventive snap connection element 10.
    These are plastic parts, which are preferably produced inexpensively by injection molding. In the present case, two snap connection elements 10 are provided on the rear side 51 of the lighting module 50. However, the number can also be varied depending on the size and weight of the module 50. For example, it would also be conceivable to arrange a snap connection element 10 in each case in the four corner regions of the illuminant module 50, provided that the module 50 has a higher weight. The number of snap-fit connecting elements 10 actually used is such that, in their entirety, they are at least capable of carrying five times the weight of the illuminant module 50. This is necessary because according to a standard, the connecting means with the support member 110 of the lamp 100 must be designed such that the holding force is five times the weight of a module to be held. With an appropriate design or number of snap connection elements 10 can thus be ensured that this standard is met and no additional security measures for holding the bulb modules 50 are required.
    As the view of Figure 3 shows, the snap connection element 10 has a central, centrally arranged abutment plate 11, from which in each case two latching regions 15 and 20 extend in the opposite direction. A first latching region 15 is designed for releasable connection to the carrier element 110, whereas the opposing latching region 20 allows the snap-in connection element 10 to be connected to the illuminant module 50. This connection with the lighting module 50 should be permanent or such that after snapping the snap connection element 10 onto the lighting module 50, the connection can no longer be readily released. Accordingly, both latching areas 15 and 20 are designed differently, which will be explained in more detail below.
    As already mentioned, the latching area 15 serves to detachably connect to the carrier element 110. It is therefore intended to enable a relatively simple snapping-on and later release of the latching. For this purpose, it has two mutually oppositely arranged latching arms 16, which are angled and accordingly each have two in an outer projection 19 merging into inclined areas 17 and 18. As a result, the regions 17 form sloping contact surfaces, which facilitate the snapping-on of the snap connection element 10 and, ultimately, of the illuminant module 50 onto the carrier element 110. When attaching from the bottom engages the narrower upper end portion of the locking portion 15 in a corresponding recess on the support member 110, wherein due to the inclined surfaces 17 then both arms 16 are pressed slightly inward until the outer projections 19 of the arms 16 the Recess in the support member 110 engage behind. At this point, both arms 16 snap outwards again and the latching with the carrier element 110 takes place.
    In the same way ensure the inclined lower portions 18 of the latching arms 16 that when pulling the arms 16 of the latching portion 15 are deflected back inwards and accordingly the latching with the support member 110 is released. As already mentioned, the configuration of the latching regions 15 and the number of snap-in coupling elements 10 used are such that the holding force realized in this way on the carrier element 110 corresponds to at least five times the weight of the luminous flux module 50 to be held. In this case, then no additional measures for holding the bulb module 50 to the support member 110 are required.
    The opposite latching area 20 in turn serves to arrange the Schnappverbin-element 10 on the light bulb module 50. Also, this locking portion 20 has two latching arms 21, which are now not designed for a detachable connection, but to ensure a permanent locking with the bulb module 50. Accordingly, the latching arms 21, unlike the latching arms 16 are not angled but straight and extend divergently each at an angle of about 30 ° from the narrower end to the side away. At their end, the arms 21 each have a step 22, which cooperates with a corresponding edge of the LED board.
    The orientation of the latching arms 21 in turn allows them to be inserted through a corresponding opening 52 or recess on the bottom side 51 of the lamp module 50 and in this case are first pressed to the inside until the end portions of the arms 21 have passed through the opening, such that the stepped areas 22 cooperate with the corresponding edges of the LED board 55 or the board engages in the step 22. This arrangement can be seen in the sectional view of FIG. 4, wherein it can be seen that the arms 21 have been pushed into the inner region of the illuminant module 50 far enough for the stepped regions 22 to rest against the edges of the circuit board 55. At the same time, the plate-shaped abutment region 11 presses against the bottom surface 51 of the illuminant module 50 from the opposite side, so that the snap-in connection elements 10 are fixed to the illuminant module 50. Since the plate-shaped region 11 obviously covers the corresponding recess 52 from the rear, there is no access from this side to the corresponding latching region 20, so that the latching connection between the snap-in connection element 10 and the illuminant module 50 is difficult or impossible to solve can be.
    According to the illustration of Figure 4, it is provided that on the bottom side 51 of the lamp module 50, a sandwich structure consisting on the one hand of the board 55 with the - not shown - LEDs and a arranged on the back of the board 55 metal plate 60 is present , This metal plate 60 serves as a planar heat sink to dissipate heat generated during the operation of the LEDs efficiently toward the rear side or to transfer to the carrier element 110 of the luminaire 10. In this case, an efficient thermal coupling between circuit board 55 and heat sink 60 is required, which is made possible by means of the snap connection elements 10 according to the invention. These are in fact dimensioned such that in the snapped state, both elements - board 55 and heat sink 60 - are firmly pressed together and accordingly present the desired thermal coupling. The snap connection elements 10 thus not only enable a detachable arrangement of the lamp module 50 on the carrier element 110 but also facilitate the construction or assembly of the lamp modules 50, since no further elements, in particular for connecting between the LED board 55 and the heat sink 60 no screw or the like are required. Of course, however, the snap connection elements 10 according to the invention can also be used if no such sandwich structure is present, but instead the LED board 55 directly forms the bottom surface 51 of the lighting module 50.
    With the help of the solution according to the invention can thus be achieved in a very simple manner a releasable fastening of light-emitting modules to a support element of a lamp. The snap connection elements used for this purpose can be produced relatively simply and inexpensively and ideally also fulfill additional tasks with regard to the joining of the individual elements of the lamp module. It should be noted that the solution according to the invention is not limited to the illustrated lamp modules but can always be used there when a corresponding module or an LED board must be releasably secured to a support member of a lamp or to a lamp housing ,
