    LUMINAIRE WITH INTERCHANGEABLE LIGHTING MODULE
    The present invention relates to a lamp according to the preamble of Anspruchs1, which has a support member on which at least one light-emitting module is arranged auswechsel¬bar. The light-emitting module can in particular be a module which contains LEDs as light sources.
    LEDs have become established not only in special applications but in all fields of lighting technology due to advances in the development of such light sources in the past. 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 much longer life. These advantages compensate for the at least currently existing disadvantage of higher production costs.
    Despite all, a change in the Licht¬quellen may also be required in lights where LEDs are used as light sources 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 are to be replaced in terms of their color to adapt the appearance or the Lichtabstrahlcharakteristik the luminaire.
    In this case, however, there is the problem that LEDs in contrast to fluorescent lamps or bulbs can not be used in a simple manner in appropriate versions and can be removed again but the change of LED boards is usually associated with a greater effort. This is also due to the fact that, within luminaires, the LED light sources usually have to 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, in particular in the case of voltages in the high-voltage range, ie at about 220V. Accordingly, the LED boards in these cases are voltages that can lead to an electric shock in the event of accidental contact, which can be harmful to health. The change of LED light sources in such lights was so far in the first place only by appropriate professionals feasible.
    The present invention is now based on the object to provide a light, are used in the lamp modules that are interchangeable. In particular, these modules should incorporate LED-based light sources, but in any case be easily interchangeable with the end user so that, for example, in the event of a module failure, it can be replaced without great delay.
    The above 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 present invention relates in particular to the question of the holder of the lamp module on the lamp or on a support element of the lamp. In order to keep the effort as low as possible, despite all, however, to ensure a reliable mounting of the module and its interchangeability, it is proposed to use a specially designed spring, which is adapted to on the one hand with the support element of the lamp and on the other hand locked with the bulb module werden.Diese preferably integrally designed spring is designed such that the desired interchangeability of the module is made possible.
    According to the invention, therefore, a lamp is proposed, which has a Trägerelementsowie at least one releasably attachable to the support element lamp module, wherein the attachment of the lamp module to the support element by means of a spring, which on the one hand to the support element and on the other hand with the light source Module can be latched. Preferably, in this case the spring is formed by a one-piece metal element, for example made of sheet metal.
    According to a preferred embodiment, the inventively used spring on two pairs of locking arms. A first pair is in this case designed to cooperate with the carrier element of the luminaire, a second pair of latching arm cooperates with the luminous means module. Preferably, in this case, the latching arms are ausgestal¬tet such that one of the latching arm pairs, preferably the first, permanently locked with the corresponding counterpart. The spring is therefore preferably designed such that it is latched einma¬lig with the support element of the lamp and then permanently remains there. The second pair of locking arms, on the other hand, which cooperates with the lamp module, preferably has a certain flexibility in order to enable the latching to be released again after the latching with the lamp module at a later time. The force of the interaction with the light-emitting module is, however, preferably measured such that it corresponds to at least five times the weight of the light-emitting module to be held. This makes it possible that the holder of the lamp module on the support element of the lamp is effected exclusively by the spring according to the invention and no further means for holding are required. In this way, therefore, it is possible to create an extremely simple solution with regard to the expense of exchangeable mounting of the lamp module.
    The two locking arm pairs are arranged according to a particularly preferred embodiment of a plate-shaped base member of the spring and aligned such that the respective connecting straight lines of the pairs are arranged rotated by 90 ° to each other. This makes it possible to design the spring in a simple way in one piece and nevertheless to achieve a high stability.
    According to a particularly preferred embodiment it is further provided that the inventive spring also serves as the holder of an electrical connection element, which cooperates with the fixing of the lamp module with a corresponding plug of the lamp module. Of course, a change of the lamp module should also be as simple as possible feasible in terms of producing the electrical connection, that is, it is preferably provided corresponding plug, the one hand on the lamp or the support element and on the other hand to the light emitting module are. Due to the fact that the spring according to the invention now also serves to support the corresponding electrical connection element, the effort required to hold the corresponding components can also be kept extremely low. The spring according to the invention thus ideally fulfills a number of tasks, an additional function being, in particular, ensuring the earthing of the lamp module. By virtue of the fact that the support element of the luminaire is usually made of metal and earthed, the spring, which is also made of metal, can also be used produce a corresponding conductive connection to the bulb module and thus ensure its grounding.
    As already mentioned, the light sources used are preferably LEDs. In this case, it can be provided, in particular, that the lighting module does not represent a single circuit board with LEDs arranged thereon, but instead forms a closed housing, in the interior of which the LEDs are arranged in a protected manner. The bottom surface of the module is preferably gebil¬det through the LED board itself, the board then encloses the LEDs ge¬ protected together with a corresponding cover. In the bottom surface, so the board then appropriate Ausnehmun¬gen or slots are provided, in which the latching arms of the spring according to the invention can eingrei fen. These arms themselves are then no longer recognizable by the light emitting surface of the lamp ago. In this embodiment, therefore, the LEDs are reliably protected against accidental contact, despite all, an end user can replace a corresponding light-emitting module without much effort.
    The invention will be explained in more detail with reference to the accompanying drawings. In the drawings: [0014] FIG. 1 is a perspective view of a luminaire in which illuminant modules according to the invention can be interchangeably arranged; FIG. 2 is a perspective view of a light source module used in the luminaire according to FIG. 1; FIG. 3 shows a view of the spring according to the invention for holding the illuminant
    module; Figure 4 is a sectional view to illustrate the operation of the spring; FIG. 5 shows a view of the carrier element of the luminaire from above with inserted spring according to the invention; and [0019] FIG. 6 shows a sectional illustration of the luminaire with the illuminant arranged thereon.
    Module.
    Figure 1 shows a perspective view of a lamp generally designated by the reference numeral 100, 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 aid of the spring described in more detail below is not limited to the correspondingly illustrated special luminaire, but can always be used when illuminant modules - in particular with LED-based light sources - detachably a support element of a lamp should 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 fastened suspended 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 greater detail below, as well as corresponding operating devices for operating the LEDs. While the LED modules are to be fastened to the support element 110 from the bottom side, in particular in an approximately C-shaped, approximately C-shaped receiving area open toward the underside, the operating devices (not shown) are preferably arranged at the rear or top side thereof. On the other side of the carrier element 110, moreover, additional light sources (not shown in any more detail) can 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 designed approximately cuboid and should be attached from the bottom to the support member 110 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 approximately a comparable width, however, it extends in the longitudinal direction of the luminaire 100 only over a fraction of the carrier element 110. For example, in the luminaire 100 of FIG. 1, about ten or fourteen such LED modules 15 are used in tandem. 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 replaceably attached to a corresponding support.
    As already mentioned, the LED module 50 is approximately cuboid. Its rear or bottom surface is in this case formed by a circuit board 51, which serves to hold a plurality of LEDs, wherein, alternatively, the bottom surface could also be formed by a flat heat sink, which is thermally coupled to the circuit board and improved dissipation during the heat generated by the operation causes. Depending on the manner in which the light output of the module 50 is to take place, the LEDs are arranged on the circuit board 51 in a matrix-like or otherwise distributed manner. A preferably completely made of a transparent material, such as cup-shaped cover 60 here forms a housing together with the board 51. In particular, the circuit board 51 and cover 60 enclose a cavity inside the module 50 in which on the one hand the LEDs are arranged and on the other hand additional optical elements for influencing the light output may be arranged. For example, the arrangement of a lens arrangement or a grid would be conceivable. It is evident 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 circuit board 51, and accordingly in this way accidental touching of the LEDs can be precluded.
    On the back of the module 50 and on the back of the board 51, an electrical contacting element 55 is further formed, via which the power supply of the LEDs takes place. This must - as described in more detail below - be coupled with a corresponding counterpart of the lamp 100 in order to ensure the power supply of the LEDs.
    In principle, different possibilities would be conceivable for arranging the LED module 50 on the carrier element 110. With the aid of the present invention, however, a particularly simple solution is provided for making the arrangement detachable, in order to enable simple replacement of the module 50 at a later time. Furthermore, the material expenditure is kept to a minimum, since - as described in more detail below - both the mechanical support and the mounting of corresponding components for the electrical contacting of the module 50 by a single component is made possible.
    This inventively designed component will be described in more detail below. It is shown in FIG. 3 and is formed by a spring generally provided with the reference numeral 10, which on the one hand is intended to cooperate with the support element 110 of the luminaire 100 on the other hand with the LED module 50. The spring 10 is, as already mentioned, formed by a one-piece sheet-metal component and initially has a flat base part 11. This is centrally provided with a recess 12 whose function will be described in more detail later. On the four sides of the base part 11 latching arms 20 and 30 are formed, which each form two Rastarm- pairs. A first pair of locking arms, formed by the arms 20, is in this case formed opposite one another on the longitudinal sides of the base part 11, the second pair of locking arms, formed by the arms 30, extends from the end faces of the base part 11. Both locking arm pairs are thus offset from one another by 90 °.
    In this case, the first pair of latching arms 20 is intended to be latched to the carrier element 110, which latching is preferably relatively strong, as a permanent attachment to the carrier element 110 is desired. Accordingly, the arms 20 are relatively rigid and have at its two longitudinal sides a toothing 21, überel a latching with high force with the support member 110 is ensured.
    The arms 30 of the second latching arm pair, on the other hand, are intended to enable a detachable connection with the LED module 50. This is achieved by virtue of the fact that these arms 30 are first of all made more flexible at their transition region to the base part 11, that is to say they can deflect in both directions in accordance with the arrow representation.
    The arms 30 are curved as shown approximately S-shaped, so that an outwardly facing projection 31 is formed, which merges at its top and bottom inein run-on slope 32 and 33, respectively. These oblique sections 32, 33 are in this case under different greatly inclined to realize the fastening and subsequent release of the module 50 in a desired manner.
    As already mentioned above, a recess 12 is formed in the middle region of the base part 11, which recess is surrounded by a plurality of guide arms 13 or corresponding projections. Two of the arms 13 have at their upper end an inwardly projecting projection, through which the holder of a corresponding electrical Gegenkupp-lungselements is made possible. This can be seen in particular in FIGS. 4 to 6, which show either corresponding sectional views of the luminaire 100 with the LED module 50 fastened thereto or the upper side of the carrier element 110. It can be seen that the holding of an electrical coupling part 120 takes place via the corresponding arms 13 and projections on the circumference of the recess 12, which is coupled to the corresponding coupling part 55 of the LED module 50 when the LED module 50 is attached to the carrier element 110. The holder of this coupling part 120 is exclusively by the spring 10 itself, other components are not required.
    The sectional view of Figure 4 can also be removed, in which way the spring 10 of the invention cooperates with the module 50. For this purpose, two recesses or slots 52 are provided in the bottom surface 51 of the module 50, in which the arms 30 can engage. The spring 10 fastened to the carrier element 110 is oriented in such a way that the arms 30 point towards the bottom side. When attaching the module 50 from the bottom while the arms 30 can engage in the recesses 52 and soft due to the inclination of the slope 33 slightly inward until the projections 31 engage behind the board 51 of the module 50. This results in an arrangement according to the representation according to FIG. 4, in which the module 50 is arranged in the receiving region of the carrier element 110 which is approximately C-shaped in cross-section. In this position, the electrical coupling between the coupling parts 55 and 120 is ensured at the same time, so that the power supply of the module 50 is also ensured.
    A release of the LED module 50 then takes place in that this is deducted downwards, which due to the particularly selected inclination of the slope 32 of the Rastarme30 now a correspondingly higher force is required. The force for releasing the module 50 or the holding force of the latching arms 30 of the spring 10 preferably corresponds to at least five times the weight of the LED module 50, which is required by a corresponding standard. This makes it possible that exclusively by the spring 10, the mechanical mounting of the module 50 takes place and no further security measures are required.
    The interaction of the latching arms 20 with the carrier element 110 can be taken in particular from the sectional view of Figure 6. It can be seen that in the region in which the spring 10 is to be arranged, laterally corresponding webs 111 are preferably arranged on the carrier element 110, which ribs are fluted on their side surface 112. The toothing 21 of the latching arms 20 then engages in this corrugation so that also here now a very strong locking between spring 10 and support member 110 is ensured. This latching is preferably only difficult or no longer solvable, since the spring 10 should remain permanently on the carrier element 110.
    An assembly of the lamp 100 is then carried out in that first the electrical coupling element 120 is attached to the spring 10 and this is then locked to the support member 110. The connections of the coupling element 120 can then be connected to the operating devices of the luminaire 100 via corresponding connecting cables. The light is then in principle operational and only needs to be equipped with the corresponding modules 50, which, however, due to the corresponding spring 10, is made possible in a simple manner in that the modules 50 are attached from the underside and locked with the spring 10. As already mentioned, the electrical coupling takes place at the same time, so that the modules 50 are supplied with power and the operation of the LEDs is made possible. The strong locking between the spring 10 and support member 110 also leads to the fact that via the spring 10, a grounding of the module 50 can be ensured. The spring 10 thus fulfills several functions which previously had to be fulfilled by numerous different components.
    Finally, therefore, the spring according to the invention makes it possible to easily attach luminaire modules to support elements of luminaires. The design of the
    In particular, spring also makes it possible, as illustrated, to fasten modules which have an enclosed housing, such that the light sources located therein are protected against accidental contact. Accordingly, the solution according to the invention is particularly suitable for the realization of luminaires with interchangeable LED-based illuminant modules.
