Description

The invention relates to a luminaire module for holding at least one luminaire element for mounting and fixing the luminaire element in a luminaire.

A generic lighting module is from the EP 2 557 359 known.

Conventional luminaires are assembled in several steps. Such conventional luminaires comprise a luminaire housing, in which luminaire elements, such as lamps or optical elements, are mounted and fixed. This is usually done by screwing the lamp elements with the lamp housing. For example, boards with LEDs are often used as lighting means, being screwed by holes provided in the board screws with a thread on the lamp housing for fixing the board. Likewise, optical elements for generating a certain radiation characteristics of the lamp are often mounted in the luminaire housing by screws or clamps that the lamps provided in the lamp housing can emit light through the optical element, so that the desired radiation characteristic of the lamp by the relative arrangement of optical element and light source is guaranteed.

It has been found that the conventional assembly of luminaires by screwing lamp elements in the luminaire housing of the luminaire is cost-intensive, on the one hand by the material costs the screws and on the other by the high amount of time that the screwing brings with it. In addition, the maintenance of such a lamp, in particular the replacement of bulbs in the lamp, as difficult, since this all screw must be solved and the new bulbs consuming in the correct position in the lamp must be brought before then re-screwing can be done.

Against this background, there are efforts to build modular luminaires, so on the one hand to reduce the cost of the lamp and on the other to facilitate the maintenance of the lamp. A first approach for such a modular design is to provide self-contained modules in which lamp elements are mounted on a support unit, these finished modules can be used in large recesses in the lamp housing and bolted to the lamp housing. This has the advantages of facilitating the maintenance of the luminaire and of making the modules separate from the luminaire, making the assembly of the luminaire simpler and less expensive. However, in this approach, a complex assembly of the module is still required in which the lamp elements with the support unit consuming, for example by screwing, must be fixed, and moreover, the module inserted into the recess must be self-supporting, so when inserting the module in the large-area recess of the lamp housing sufficient stability is ensured, and further must be provided on the module itself, especially when boards are used with LEDs as lighting means cooling elements. The corresponding cost-intensive construction of such a module requires that the cost savings in the manufacture of a lamp in the mentioned approach of a modular structure is low.

The invention is therefore an object of the invention to provide a lamp module for holding at least one lamp element for mounting and fixing the lamp element in a luminaire, which at least partially overcomes the above-mentioned disadvantages of known modules and can contribute to a simple, inexpensive and easy to maintain construction of a lamp ,

According to the invention, the stated object is achieved by providing a luminaire module which comprises two longitudinal side by side, in particular parallel side walls, which are interconnected by transversely extending transverse webs, wherein the side walls are vertical to that of the longitudinal direction and the transverse direction extend defined level. The side walls do not necessarily have to run continuously in the longitudinal direction of the luminaire module. For example, the side walls can also be represented by side wall elements arranged side by side in the longitudinal direction and spaced from one another, which are connected to one another in the longitudinal direction, wherein the side wall elements can be cuboid or cylindrical, for example. Preferably, such side wall elements are arranged linearly next to one another in a straight line, so that the side wall formed by the side wall elements runs straight in the longitudinal direction. However, the side wall elements can also be arranged next to one another in such a way that a longitudinally curved profile of the side wall formed by the side wall elements results. Accordingly, a continuously formed side wall in the longitudinal direction can run straight or curved. A straight course of the side wall can bring the advantage that a lamp element is particularly easy to insert between the side walls. A curved course of a side wall can have the advantage bring themselves that a inserted between the side walls lamp element is particularly well managed. In particular, the course of the two side walls in one exemplary embodiment does not necessarily have to be identical. In one embodiment, the course of the side walls in the longitudinal direction is identical.

On at least one of the side walls, at least one lateral web is arranged, which extends in the transverse direction and vertically from the transverse webs, d. H. vertical to the plane defined by the longitudinal direction and the transverse direction. Like the side walls, the lateral web does not necessarily have to run continuously over the longitudinal extent of the luminaire module. For example, the web may comprise longitudinally spaced-apart web elements. In this case, the transverse webs, the side walls and the at least one lateral web or the lateral webs are arranged to each other so that they comprise a gap at least in sections, in which the lamp element is inserted in the longitudinal direction, wherein the gap has planar openings between the transverse webs are arranged. The at least one lateral web has a holding element for holding the lamp element, which is resilient in the direction of the transverse webs and for generating a contact pressure on the lamp element to the transverse webs, wherein a fixing element, in particular on the at least one lateral web, vertically spaced from the transverse webs is provided for holding the lamp element, wherein the fixing element is resilient in the direction of the transverse webs, wherein the fixing element is further removed from the side wall on which the lateral web is arranged, as the holding element.

By the retaining element can thus on a lamp element which is inserted into the intermediate space, a contact pressure generated to the transverse webs. As a result, the luminaire module according to the invention is designed so that a lamp element to be held in the intermediate space may possibly be held in pressure contact between the holding element and transverse webs in the luminaire module. For example, in one embodiment, two or more to be held in the gap luminaire elements are vertically stacked in the space, the holding element can exert a contact pressure on him nearest lamp element, the contact pressure of this lamp element at least partially to at least one of the other Luminaire elements for holding the at least one further luminaire element can be passed. Furthermore, the holding element can exert on the space to be held in the space lamp element or arranged in the space lamp elements a contact pressure against a force exerted externally by the surface openings vertically on the lamp module force, whereby the lamp module can be pressed against a force generating device this device ,

In this case, the holding element can be designed differently. For example, the holding element can be formed continuously in the longitudinal direction or else also comprise holding element sections which are spaced apart from one another in the longitudinal direction. For example, the holding element can be arranged as an additional component on the lateral web. For example, the retaining element may be formed integrally with the lateral web. For example, the holding element can be realized by the shape of the lateral web itself. The holding element can be realized for example by the side facing the transverse webs side of the web page. For example, the lateral web may have a corresponding profiling, which represents the holding element. For example, the holding element several, in particular in the longitudinal direction comprise spaced apart, integrated in the web bending springs. The bending springs can thus represent the holding element sections. For example, such bending springs may be integrally formed with the web, for example by integrated into the web, hook-like projections which are elastic to the web.

The intermediate space is not enclosed by the transverse webs, the side walls and the at least one lateral web. Rather, the gap on planar openings, which are arranged between the transverse webs. In particular, in one embodiment, the planar openings may be defined by the transverse webs and the side walls, so that the planar openings between two adjacent transverse webs and the side walls are closed in a flat manner. Preferably, the areal openings are formed so large that the surface occupied jointly by the entire areal openings of the luminaire module make up a substantial portion of the cross section of the luminaire module in the plane defined by the longitudinal direction and the transverse direction, in particular a proportion of more than 50% of this cross section , in particular a proportion of more than 70%, in particular a proportion of more than 90% of this cross section.

The luminaire module according to the invention has the advantage that luminaire elements can be introduced into the luminaire module in a particularly simple manner and held in the luminaire module. Thus, in one embodiment, associated lighting elements, without additional fixation measures are required to be inserted laterally into the gap of the lamp module, wherein a sufficient holding force for holding the lamp element is ensured in the lamp module by the interaction of transverse webs and retaining element. The transverse webs give the lamp module according to the invention a sufficient Stability.

Due to the large-area openings between the transverse webs ensures that a lamp module in which a lamp element is arranged, can be arranged in a corresponding lamp housing, that the lamp element, which can experience a contact force to the transverse webs through the holding element, in the planar openings arranged contact points of the lamp housing abut flat against the lamp housing and can be kept. In the case of several luminaire elements arranged vertically one above the other, this applies correspondingly to the totality of the luminaire elements. As a result, a particularly high stability of the lamp module is required for a reliable and durable installation of a lamp element by means of the lamp module in a lamp housing, as brought in a fixation of the lamp module with a lamp module arranged in the lamp element, the lamp element on the flat openings in direct contact with the lamp housing can be. In addition, for example, when the lamp element is designed as a board with LEDs, a cooling contact between the lamp housing and lamp element can be ensured on the surface openings. For this purpose, in particular the provision of correspondingly large area openings may be advantageous.

The luminaire module according to the invention further comprises, in particular on the lateral web, a fixing element for holding a lamp element, wherein the fixing element is vertically spaced from the transverse webs and is resilient in the direction of the transverse webs. The fixing element may be arranged, for example, on a further lateral web or directly on the side wall. Like the retaining element also allows the fixing thus a reliable holding of the lamp element in the Interspace, by being able to generate a contact pressure on the lamp element to the transverse webs out. In one embodiment, the lighting element between fixing and transverse bars can be maintained. The fixing can be formed continuously or interrupted in the longitudinal direction. For example, a luminaire element can be held in the luminaire module at the same time by fixing element and retaining element. In one embodiment, the holding element holds a first luminaire element and the fixing element holds a second luminaire element. In a further embodiment, two lamp elements may be provided in the lamp module, which are arranged one above the other, wherein the holding element can exert a contact pressure on the first lamp element for holding the first lamp element, and wherein the fixing element can exert a contact pressure on the second lamp element, whereby the second lamp element on the first lamp element and on the transverse webs or, for example, on a protruding through the planar openings in the intermediate device to which the lamp module is attached, may be pressed.

The fixing element is further removed from the side wall, on which the lateral web is arranged, as the holding element. This can be ensured, for example, holding a lamp element in the lamp module, in which the holding element exerts a contact pressure on the lamp element close to the side wall and the fixing near the transverse center of the lamp module exerts a contact pressure on the lamp element, so that the lamp element evenly by holding element and Fixing a contact pressure, for example, learns on the transverse webs. Also, for example, in a corresponding arrangement, a first lamp element can be pressed by the closer to the side wall holding member to the transverse webs, while a second lamp element by the fixing is pressed closer to the transverse center of the lamp module to the transverse webs. The corresponding arrangement may also be advantageous if the fixing element exerts a contact pressure on a second lamp element and also on a first lamp element, wherein the lamp element is additionally held by the holding element, so that a uniform contact pressure is ensured to the transverse webs.

The luminaire module according to the invention thus enables a reliable fixation of the luminaire element or the luminaire elements by the guidance and holding of a luminaire element or the luminaire elements and can be produced particularly cost-effectively because of its fiction-specific structure, since no particularly high demands are placed on the stability of the luminaire module have to. The luminaire module according to the invention can be designed to hold at least one standardized luminaire element. By providing standardized luminaire elements, the production of luminaires can be further simplified and discounted. For example, standard dimensions can be provided for standardized luminaire elements, which are matched to the dimensions of the luminaire module according to the invention, so that a standardized luminaire element can be held in the luminaire module. For example, from a pool of standardized luminaire elements, certain luminaire elements can be selected for the realization of a specific luminaire with particular properties. The luminaire module according to the invention thus enables on the one hand the cost-effective production of luminaires and, on the other hand, the simple replacement of luminaire elements for the maintenance of the luminaire.

The two lateral webs can be formed identically in one embodiment and each comprise an identical holding element and possibly also an identical fixing element. However, the lateral webs, which are each arranged on a side wall, can also have a different design, for example, a lateral web can have only one retaining element and the other lateral web holding and fixing element. Just by an advantageous embodiment comprising two lateral webs, each of which is arranged on a side wall, a particularly uniform contact pressure on one or more lighting elements can be ensured.

Preferably, the fixing element is designed as a profile in the lateral web. Thus, the fixing element can be integrated directly in the lateral web or the lateral web directly act as a fixing. As a result, a particularly favorable production of the lamp module is possible. In particular, the fixing element may be arranged on the side wall opposite the end of the lateral web. This can be between a lamp element to be held and the fixing a Form interface over which presses the fixing element on the lamp element, which promotes in particular a slight insertion of the lamp element in the lamp module.

Preferably, fixing element and retaining element on the lateral web are so far apart from each other that they can exert a spring force on a lamp element to the transverse webs substantially independently of each other.

Preferably, the at least one lateral web is subdivided into separate longitudinal sections. As a result, a better elastic property of the lateral web can be ensured, which can be advantageous in particular for the spring force exerted by the fixing element and / or the retaining element on a lamp element.

In one embodiment, latching lugs are arranged on the side facing away from the gap side of the side walls for latching a lamp cover to the lamp module.

In FIG. 1a in each case an exemplary embodiment of a luminaire module 1 according to the invention, a circuit board 2 according to the invention and an optical element 3 according to the invention are shown. The luminaire module 1 is designed so that the side walls 7, the transverse webs 8, the lateral webs 9, the holding elements 5 and the fixing elements 6 and the latching hooks 10 are formed as a one-piece component. In addition, this includes in FIG. 1a shown lamp module 1 two head pieces 4, each complete a longitudinal end of the lamp module 1. While in FIG. 1a the lamp module 1, the board 2 and the optical element 3 as are shown separate components, is in FIG. 1b the lamp module 1 is shown after the optical element 3 and the board 2 were inserted into the lamp module 1 in the longitudinal direction and the head pieces 4 were fixed to the longitudinal ends of the lamp module 1 by latching on the lamp module 1. The respectively in the FIGS. 1a and 1b shown components are identical.

Out FIG. 1a it can be seen that the lamp module 1 comprises two longitudinally parallel side walls 7, wherein on the side walls 7 latching hooks 10 are arranged, wherein the side walls 7 at the height of the latching hooks 10 in sections has recesses to ensure the elasticity of the latching hooks 10. The side walls 7 are interconnected by transverse webs 8. At the transverse web 8 facing away from the vertical end of the side walls 7 are each a lateral web 9 is arranged, which extends in the transverse direction. However, the lateral webs 9 do not extend from the side wall 7 to the transverse center of the lamp module 1, so that the lateral webs 9 are spaced from each other. Thus, the transverse webs 8, the side walls 7 and the lateral webs 9 comprise the gap in sections and not closed. Rather, the gap in the area in which the lateral webs 9 are spaced from each other, is open. In addition, the gap has planar openings which are arranged between the transverse webs 8. The planar openings extend in a closed area between two adjacent transverse webs 8.

The side walls 7 and arranged on the respective side walls 7 lateral webs 9 are each formed identically. The lateral webs 9 are divided into separate longitudinal sections. As a result, an elastic property of the side webs 9 is ensured. This elastic property means that the lateral webs 9 under the action of a vertical force, ie a Force acting perpendicular to the plane formed by the longitudinal extent and the transverse extent of the lamp module, can be deflected at an angle to the side walls 7. The lateral webs 9 each comprise a holding element 5. The holding element 5 is formed integrally with the associated lateral web 9 and comprises a plurality of integrated in the lateral web 9 bending springs 55. The torsion springs 55 are discussed below in connection with FIG. 2a explained in more detail. At the lateral webs 9, a fixing element 6 is also provided. About the described elastic of the lateral web 9, the fixing element 6, which is arranged on the lateral web 9, resiliently formed in the direction of the transverse webs 8. In the illustrated embodiment, the fixing element 6 is incorporated as a profile in the lateral web 9.

As in FIG. 1a it can be seen that the head pieces 4 locking devices with which they can be locked to the side walls 7 of the lamp module 1. On the other hand, the head pieces 4 lock the optical element 2 and the board 3 after being pushed into the intermediate space of the luminaire module 1 against movement in the longitudinal direction.

In FIG. 1a Furthermore, a circuit board 2 according to the invention with LEDs 11 is shown. The LEDs 11 are arranged linearly in a row. The corresponding optical element 3 is also linear, ie straight, so that the optical element 3 can be arranged above the LEDs 11 of the board 2 and thus can specify the emission characteristic of the LEDs 11 of the board 2.

In FIG. 1b are luminaire module 1, board 2 and optical element 3 assembled shown. The head pieces 4 are latched to the longitudinal ends of the lamp module 1, so that the optical element 3 and 2 board in the longitudinal direction not can move.

The assembly situation of luminaire module 1, board 2 and optical element 3 is in the FIGS. 2a and 2 B shown in more detail. The holding elements 5 and the fixer elements 6 do not directly exert a contact pressure on the board 2 and the optical element 3 on the transverse webs 8 in the assembled state of the luminaire module 1, the board 2 and the optical element 3. Rather, a small clearance is provided between the transverse webs 8 and the board 2 in the assembled state of rest. However, retaining elements 5 and fixing elements 6 hold the optical element 3 and the board 2 in the luminaire module 1, since they limit the vertical movement of the board 2 and the optical element 3. In the illustrated embodiment, the fixing elements 6 are formed as an oblique profile on the lateral webs 9. As a result, a centering of the optical element 3 is ensured in the desired position in the lamp module 1.

In particular from FIG. 2b It can be seen that the optical element 3 is arranged above the LEDs 11 of the board 2, in order to predetermine the Abstrahlchärakteristik the LEDs 11, with which the LEDs 11 can radiate through the area resulting from the distance of the lateral webs 9 from each other. The optical element 3 has corresponding sections to the fixing elements 6, which ensure reliable together with the fixing elements 6 of the centering of the optical element 3 in the lamp module 1. In addition, the optical element 3 has standing areas 33 with which the optical element 3 can rest flat on the circuit board 2. As a result, destruction of the board 2 is reliably prevented. From the FIGS. 2a and 2 B It can be clearly seen that a fixing element 6 is further away from its associated side wall 7 than the holding element 5, which is arranged on the same lateral web 9. Because of its small distance from the side wall 7, the holding element 5 experiences hardly any elastic restoring force of the lateral web 9 at a load of the holding member 5 in the vertical direction. In contrast, the fixing element 6 is arranged on the side wall 7 opposite the end of the lateral web 9, so that the lateral web 9 provides the resilient action of the fixing element 6. It is obvious that the resilient effects of the holding element 5 and the fixing element 6 are each independently of one another and that the holding element 5 and the fixing element 6 do not essentially influence each other.

In particular from FIG. 2a It can be seen that the torsion springs 55 of the retaining element 5 are integrated in the lateral web 9 and point like a hook on the transverse webs 8. Thus, the bending springs 55 of the holding element 5 provide a spring action per se.

As explained, retaining elements 5 and fixing elements 6 in the assembled idle state of luminaire module 1, circuit board 2 and optical element 3 do not exert any contact pressure on optic element 3 and circuit board 2. The final fixation of board 2 and optical element 3 in the lamp module 1 thus takes place only when the luminaire module 1 with board 2 and optical element 3 in a luminaire housing according to the invention. In this case, the board 2 and the optical element 3 are pressed over the flat openings of the intermediate space to the lamp housing. The contact force required for this purpose is provided by the interaction of latching hooks 10 with holding elements 5 and fixing elements 6. For this purpose, the latching hooks 10 are formed so that it generates a force on the lamp module 1 with a component vertically from the lateral web 9 to the transverse webs 8 during the latching in Verrastaussparungen 13 of the lamp housing. As a result, the luminaire module 1 with the circuit board 2 can be pressed against a luminaire housing.

In FIG. 3 the rear view of an embodiment of a luminaire module 1 according to the invention with a circuit board 2 and an optical element 3 is shown. Out FIG. 3 It can be seen that the back of the board 2 are accessible through the surface openings between the adjacent transverse webs 8 from the back. Accordingly becomes out FIG. 3 clearly that through the interaction of latching hooks 10 and retaining elements 5 and fixing elements 6, the board 2 can be pressed against a luminaire housing with their surfaces which are arranged in the surface openings of the intermediate space, when the transverse webs 8 received in receiving recesses 12 of the lamp housing become.

In FIG. 4 the use of a luminaire module 1 according to the invention with optical element 3 according to the invention and circuit board 2 according to the invention is shown in a luminaire housing according to the invention. The luminaire housing has receiving recesses 12 and locking recesses 13. In FIG. 4 a robot arm 14 is shown with suction cups. About the suction cups of the robot arm 14 engages the lamp module 1, in which board 2 and optical element 3 are located, and locks the lamp module 1 with the lamp housing. In this case, the latching hooks 10 engage in the latching recesses 13, while at the same time the transverse webs 8 are received by the receiving recesses 12 and sink into these receiving recesses 12. Through the synopsis of FIG. 3 and FIG. 4 It can be seen that in the latching of latching hooks 10 with Verrastaussparungen 13 and the simultaneous sinking of the transverse webs 8 in the receiving recesses 12, the board 2 with its flat areas, which lie in the surface openings of the gap, rests flat against the lamp housing. Due to the interaction of latching hooks 12 and Verrastaussparungen 13 and retaining elements 5 and fixing elements 6, the board 2 against the Luminaire housing pressed.

In other embodiments, holding elements 5 and fixing elements 6 already exert a contact pressure on the optical element 3 and the printed circuit board 2 on the transverse webs 8 in the assembled idle state. This requires a particularly accurate coordination of the luminaire module 1 according to the invention with the corresponding circuit boards 2 and optical elements 3 according to the invention, but makes it possible to retain the optical element 3 and the circuit board 2 already in the quiescent state of the luminaire module 1 assembled with the circuit board 2 and the optical element 3 and can thus damage the optical element 3 and prevent board 2.

It can be seen from the described embodiments that the invention enables a modular assembly and a modular construction of luminaires. A luminaire module 1 can be combined with different boards 2 and different optical elements 3, wherein a particularly favorable structure can be achieved by the special design of the components according to the invention, since the board 2 can be pressed directly to the luminaire housing, so no high demands on the Stability of the lamp module 1 must be made to accommodate board 2 and 3 optical element. The modular construction according to the invention is particularly suitable for automatic industrial series production, wherein in pre-punched receiving recesses and Verrastaussparungen 12, 13, the fully populated lamp module 1 can be inserted and locked with the lamp housing.
