Description

The invention relates to a luminaire arrangement for luminaires, which should be equipped in particular with LEDs.

LED holders for spotlights, for example, are known. These holders are known to have a soldered to a light module wiring. The soldered board (with the LEDs) is attached to a plastic holder as a connecting element. This holder is usually used in addition to receiving optical elements such as reflectors.

Due to the large number of variants of lighting and possibly additional elements such as reflectors creates a large number of board variants, which has a corresponding storage and thus increased storage and cost.

In addition, solder connections for the wiring to the outside with respect to the respective light module for powering the lamps have the disadvantage that the resulting soldering point protrudes from the board in the direction of plastic holder or frame body. This means that when connecting or placing the plastic holder or plastic frame on the board this does not always rests flat on the board. It may instead come to deformations of the plastic frame during mounting, which may have a negative impact both in terms of the radiation properties and the material properties of the lamp.

Another problem may arise from the fact that due to the screwing of the plastic frame with the board, both parts are initially aligned well with each other. However, due to thermal effects occurring during operation, degeneration in the plastic holder may occur. Thus, the overall structure of a mechanical warping subject, which may have a negative impact on the optical properties of the overall construction, for example, due to the resulting mechanical stresses in the respective, warping material, which is reflected in a change in the relative position of the lamps on the board to the plastic frame can. Or the board changes its position in relation to other elements, such as a luminaire housing. In any case, it can not be guaranteed that the light will continue to be emitted as desired. Likewise, the frame may fail premature fatigue, such as cracks, due to stresses that occur.

A change in the Lichtabstrahlcharakteristik can be caused in operation due to mechanical stress such as vibrations. Such shocks can be, for example, construction or modernization work.

Therefore, spring frames have been developed, which are, however, mounted on still soldered to the external wiring boards. As a result, the problem of the flat resting of the boards and thus also the warping or the influence of mechanical loads was still present, but contained. However, the disadvantages due to the bending caused by the soldering and thus distortion of the frame body during assembly, storage and costs have not yet been solved.

In addition, the installation of such units is error-prone. The board must first be soldered to the external wiring and then inserted into the holder as a whole. This causes the solder joints to break. The tearing of such compounds is difficult to detect sensory, and fixing is difficult. A receptacle for a specifically developed, photometrically high-quality reflector optics assembly is not easy. Sometimes there is no defined pressure of the LED module on a reflector or holder or on a heat sink. Due to these disadvantages, in particular automated production is very difficult, and the operational reliability can not be guaranteed, in particular with regard to heat dissipation over the service life. In addition, a separate module with soldered connection cables is necessary for each type of luminaire, which is also unfavorable for the production costs.

The object of the invention is therefore to counter the remaining disadvantages.

This object is achieved by means of the subject matter of patent claim 1. Advantageous developments are specified in the subclaims.

According to the invention, a luminaire arrangement with a lighting module and a holder is provided. The light module comprises, as the name implies, at least one light source which emits light when it is supplied with electrical energy. Any kind of light source comes into question: (preferred) LED (s), OLED (s), incandescent lamps, etc. The holder has a mounting section on or in which the lighting module is provided. Furthermore, the holder has an electrical coupling element. This coupling element is provided on the holder such that the lighting module is in touching contact with the electrical coupling element by provision on or in the mounting section. Ie. merely by provision, d. H. Montierens, the light module reaches this with the coupling portion in touching contact. According to the invention, an electrical coupling to the outside with respect to the holder is provided via the said contact contact and the electrical coupling element. On the one hand, therefore, the touch contact produces an electrical coupling from the lighting module to the coupling element. On the other hand, the coupling element is accessible from the outside with respect to the holder to be coupled with electrical elements such as a wiring, whereby the electrical power supply of the lighting module can be easily made. By means of this coupling element, it is possible to construct the arrangement comprising the lighting module and the holder as a (larger) module and then again as a structural unit, for example, on or in a holding element such as a light housing on or accommodate.

The coupling element preferably has a connection section for electrical coupling to the outside. This coupling portion is therefore accessible from the outside with respect to the electrical contact. This makes it possible to obstruct the light module, to be able to use the light assembly as a module at the destination and thereby be able to electrically couple or connect afterwards. This facilitates the assembly. In addition, the luminaire assembly can be installed ex works and finally assembled later, making on-site handling much easier.

The connection section is preferably designed as a plug-in contact for connecting an external electrical wiring. This represents a particularly simple type of electrical coupling with an external power supply. In addition, standardized connections to the luminaire arrangement can thus be provided. The or the connections of the light module, however, may be completely different and tailored to the particular application. Also is an adaptation or Extension to changed connection options possible without having to change anything on the light module. The light module is therefore universally applicable; the holder with contact element forms a kind of adapter.

The coupling element is preferably arranged at least in regions between the mounting section and the lighting module. Ie. when assembling the lamp assembly, the coupling element can be used for example in the holder and then clamped by the light module in the simplest case. The assembly can be done without further, additional funds.

The aforementioned mounting portion preferably has retaining means integrally formed with the holder for receiving the lighting module. This allows the light module without the use of other means already during insertion or placement in or on the mounting portion of the holder (pre) to be able to fix. This can be done for example by means of latching and / or clamping sections. As a result, the assembly is enormously easier.

Each of the aforementioned holders may further comprise a mounting portion. This serves to attach the holder in or on the above-mentioned holding element. The luminaire arrangement according to the invention can thus be part of a larger arrangement. Such an arrangement may be, for example, a suspended ceiling having a plurality of such lighting arrangements. Or the luminaire assembly can be used in a luminaire housing as a holding element with the outer shape, for example, similar to a classic incandescent lamp. It can therefore be modeled on any conventional light. Ie. the luminaire housings (or reflectors) do not need to be modified, so there are no additional costs for these elements.

The holding element may therefore comprise at least one of the following elements: a driver housing, a luminaire housing, a holding frame, a heat sink, a heat conducting element and / or a mounting element.

Ie. The holding element can fulfill a wide variety of functions and is not limited to a specific function. This means that the luminaire arrangement according to the invention can be used universally.

The holder may be resilient. Alternatively or additionally, the luminaire arrangement may also have a spring element. A spring effect achieved on account of the resilient design or of the additional spring element is effective according to the invention in particular due to an attachment of the holder via the attachment section or in the installed state of the luminaire arrangement. The resilient effect causes thermal and / or mechanical stresses such as temperature changes or vibrations that are exerted on the arrangement in which the luminaire arrangement according to the invention is arranged, not or only insignificantly on the luminaire arrangement and thus possibly on the electrical coupling between the coupling section and light module are transmitted. As a result, the electrical coupling is maintained, which the reliability of the lamp assembly benefits, and this despite the changed, still existing, now less vulnerable electrical coupling. And due to the mechanical decoupling of the electrical connections between the light module (or its board) and the external wiring, thermal and / or mechanical stress on the holder can not or significantly less impact on the board; There are no forces at the coupling point between the coupling section and the light module, which would have to be recorded. Such loads are absorbed by the fact that the electrical coupling between the light module and coupling section is loose or this is compensated. In addition, the construction thereby contains a constant pressure of the light module on the heat conducting part, if present. Thus, improved heat dissipation is ensured, for example, via a heat sink over the entire life of the luminaire which can be formed or equipped with the luminaire arrangement according to the invention. Further, the spring action, for example, when fastening means (eg screws and the like) provided for attachment via the attachment sections, ensures that a certain prestress is maintained at the connection point and thus the connection is secured, whereby, for example, additional washers can be dispensed with.

The aforementioned spring element is preferably resiliently connected to a first region of a first side on the holder and to a side facing away from the holder on the lighting module or an element holding or supporting the lighting module. Ie. the fastener and the holder are decoupled from each other in terms of the aforementioned possible mechanical loads, so that these loads, as also stated in advance, hardly on the holder and thus on the electrical coupling, in any case not to maintain the electrical coupling between the light module and coupling section.

The coupling element is preferably held in position by the holder and / or the spring element. Alternatively or additionally, the coupling element is attached to such a portion of the spring element, which is prevented from changing its distance from the holder. Ie. the coupling portion is fixed by means of the spring element and can be mounted with the mounting of the holder on the element, so not necessarily with the light emitting module. This further simplifies the assembly, since the mounting of the light module can be done separately from the mounting of the coupling section.

The mounting portion preferably has a passage opening which is formed such that the lighting module radiates light through the passage opening by means of its at least one light source. As a result, the light module can be arranged with respect to the radiated light at a rear side of the holder. Ie. The holder protects the light module in the direction of light emission direction to the outside, which benefits the reliability.

The at least one luminous means of the luminous module preferably projects into the passage opening of the mounting section. By way of example, the region of the holder around the through-opening can then be designed to be light-reflecting on the side facing away from the lighting module (that is, the side surrounding the lighting means at least laterally). Ie. The holder can also take on a light-influencing function as that of a luminaire reflector. This eliminates the need for otherwise necessary parts, which keeps the overall structure simple.

The luminaire arrangement according to the invention can furthermore have a heat-conducting element which is coupled in a heat-transmitting manner to the luminous module. This makes it possible to dissipate heat generated by the light module possibly in operation and thus to avoid overheating of the light module or the light assembly with the associated risk of damage, which benefits the reliability and durability of the installed parts.

The heat-conducting element is preferably arranged on a side of the lighting module facing away from the holder. As a result, the heat conducting part can be optically disposed and do not protrude into the lighting area of the light module. This also allows the direct heat coupling between the light module and the heat conducting part, which allows short heat transfer paths away from the light module.

The heat-conducting element is preferably formed plate-like. Ie. it has a very small overall depth, which leads in conjunction with the other lighting arrangement to a very short-building unit. This opens up a variety of applications, for example in a light bulb-shaped housing, a control gear with small or flat space and in other areas. The luminaire arrangement thus formed thus remains very flexible.

Preferably, each of the aforementioned lamp assemblies further comprises a mounting member which includes the light module together with the holder, preferably fixed in place. Ie. The mounting element serves the purpose of summarizing the light assembly to a module, ie a structural unit. This makes it possible to pre-assemble the luminaire arrangement and subsequently to be able to use it at the respective destination. It is therefore a standard lighting arrangement possible, which may be formed in the final shape, for example, incandescent, reflector lamp-like, with a flat light exit surface or otherwise, depending on how the particular application.

The mounting member preferably has a through hole extending in the mounting direction of the mounting member with respect to the holder (away from it). This makes it possible to provide this passage opening, for example, as a heat dissipation opening, through which the light module can deliver its heat. For example, a fan could be inserted in such an opening.

In the presence of one of the aforementioned heat-conducting elements, the mounting element can be designed to surround at least two opposite edge sections of the heat-conducting element by means of mutually facing edges of the through-opening. Ie. the mounting element holds the heat-conducting element. This makes it possible to attach the heat-conducting element in advance on the mounting element and then to be able to attach as a combined assembly and heat dissipation unit as a module on the holder. In this case, the passage opening is advantageously designed so that the heat-conducting element passes heat-transmitting in mounting this unit with the light emitting module in coupling.

Alternatively or additionally, the mounting element itself is designed as a heat conducting element. This means that the mounting member has a dual function: mounting and dissipating heat, whereby the number of necessary parts can be kept low.

Preferably, each of the aforementioned holders has positioning structures which enable a rotationally secure mounting of a respective element to be attached thereto, such as the light-emitting module, the mounting element, the heat-dissipating element and the like. Ie. the respective element can only be mounted in a single position on the holder. If it rotates with respect to the holder, it can not be attached correctly. The rotation can be realized for example by means of a respective, eccentrically arranged mounting pin on which the respective element must be placed with a corresponding mounting recess. This simplifies assembly and reduces the risk of assembly errors.

Each of the aforementioned lamp assemblies may further include an optical section. This is provided on and / or in the holder in order to cooperate optically with the light emitted by the light module in a predetermined manner. This optical interaction means influencing the radiated light in any manner such as: luminous color, luminous intensity, radiation characteristic such as scattering, focusing or light emission angle, and the like. As a result, the versatility of the light assembly is further increased.

The optical section preferably has an optical element which is arranged in the optical path of the light emitted by the light module. Alternatively or additionally, this element has a reflector, which is provided in the holder.

The invention further relates to a luminaire having a holding element, in particular a luminaire housing, and a luminaire arrangement provided on or in the holding element according to the invention.

Further features and advantages of the invention will become apparent from the following description of a preferred embodiment. Show it:

FIG. 1

a luminaire arrangement according to a first embodiment of the invention and

FIG. 2

a detailed view of the embodiment of FIG. 1 ,

FIG. 1 shows a luminaire assembly 1 according to a first embodiment of the invention.

The arrangement 1 comprises a lighting module 40, which by way of example has a lighting means 41. This thus at least one light-emitting means 41 is formed by way of example by means of a LED arranged in the middle. Furthermore, contacting points 42 are here formed at a right upper and lower left corner, which are coupled to the lighting means 41 and allow a connection with respect to the arrangement 1 to the outside. The contacting to the outside by means of connecting pieces 2, which are formed here by means of individual lines whose conductors are electrically coupled to the respective contact point 42 of the light-emitting module 40. Other types of fittings are also conceivable, such as touch contacts and the like.

The luminaire arrangement 1 further has a holder 10, which in turn has a mounting portion 11, on or in which the lighting module 40 is provided. The mounting portion 11 may preferably integrally formed with the holder 10 holding means - for example in the form of locking means, grooves and the like - for receiving the light-emitting module 40 has.

The holder 10 or the mounting portion 11 may have a through opening 17, through which the light module 40 is able to emit light by its illuminant 41 in turn towards the front of the holder 10 when the light module 40 is energized.

In principle, however, it is also conceivable that the lighting module 40 is rotated by 180 ° with respect to the holder, that its lighting means 41 is directed away from the holder 10. In this case, the contacting sites 42 are then preferred on the back of the light module 40 - so the holder 10 faces-provided.

Optionally, the light module 40 is seated at its rear side pointing back here on a hotplate 30 as a heat-conducting element, which bears heat-transmittingly on the light-emitting module 40. The heat plate 30 is formed from an electrically non-conductive material, which is also thermally very good thermal conductivity. The heat plate 30 and the light module 40 are placed here on the holder 10 from behind. Thus, it is possible for the light-emitting module 40 to emit excessive heat during operation, specifically to the heat-conducting plate 30. The heat plate 30 according to the exemplary embodiment shown essentially corresponds to the light-emitting module 40 in its external dimensions, the invention not being limited thereto.

In order to fix the elements 30, 40 on the holder 10, either previously designated integrally formed with the holder 10 holding means are provided on the holder 10. Alternatively or additionally, it is also conceivable that at least the heat-conducting plate 30 by means of the holder 10 here right and left screw holes 12 and a mounting plate 50 has, which forms a mounting element, wherein the corresponding elements 30, 40 are clamped between the holder 10 and mounting plate 50 , If the light-emitting module 40, as described above, held with the integrally formed with the holder 10 holding means, the light-emitting module 40 on the one hand and the heat-conducting plate 30 on the other hand provided so that there is a two-dimensional physical contact.

The mounting plate 50 is from the perspective of the holder 10 behind the light module 40 and the heat conducting plate 30, respectively. In order to fix the fastening plate 50 to the holder 10, the fastening plate 50 preferably has screw openings 51 at corresponding locations which correspond or are aligned with screw openings 12 of the holder 10. As a result, the fastening plate 50 can be fixed to the holder 10 by means of screws 3.

The screw holes 51 advantageously have internal threads, so that the screws 3 can be screwed into the mounting plate 50 and thus fix the three-piece arrangement consisting of light module 40, heat-conducting plate 30 and mounting plate 50 to the holder 10. As a result, it is possible to optimize the heat-conducting plate 30 for its heat-conducting function. It's not necessary, to form the heat conducting plate 30 with respect to a fastening function. In order to dissipate the heat effectively, the mounting plate 50 is preferably formed of metal. The heat-conducting plate 30 may be formed from a suitably flexible material so as not to damage the structures on the light-emitting module 40 on the rear side facing away from the holder 10. The mounting plate 50 may be formed of a suitably stable material and / or provided with stability-enhancing structures.

However, the mounting plate 50 does not have to be formed of a good heat-conducting material. In particular, in this case, the mounting plate 50 preferably has a through hole 53 which is formed so that while the heat conduction plate 30 engages behind, but leaves a corresponding space, so that the heat conducting plate 30 is able to absorb the heat absorbed by the light module 40 at the to be able to deliver the rear side facing away from the light module 40; For example, to a heat sink of a lamp. For this purpose, T-shaped projections 52 are exemplarily formed on the mounting plate 50 here above and below, which extend from an outer edge region of the mounting plate 50 in the through hole 53 or protrude, they have a distance to each other, which is less than one here Height dimension of the heat conductor plate 30. As a result, the mounting plate 50 is possible to engage behind the heat-conducting plate 30 from the side facing away from the holder 10 and thus fix the two-piece arrangement, consisting of light module 40 and heat conducting 30, to the holder 10.

Furthermore, an assembly aid 60 can be provided with which the installation of the light assembly 1 is simplified. In this case, the attachment plate 50 may, for example, have two depressions 55 which extend in the direction of the assembly aid 60-ie away from the holder 10 in the installed state-and project from the rear side of the attachment plate 50 facing away from the holder 10.

The thus projecting away from the holder 10 projections correspond with corresponding recesses 62 of the mounting aid 60. During assembly, the mounting plate 50 is inserted by means of the recesses 55 in the recesses 62 of the mounting aid 60 and thus fixed in the mounting position and positioned defined. Thereafter, the heat-conducting plate 30 is placed on the mounting plate 50, here on the projections 52, and the heat-conducting plate 30 is here right and left side of edge portions 54 of the mounting plate 50 attached. The light module 40 is turned on the heat-conducting plate 30 is placed. The projections 52 preferably extend somewhat in the direction of the assembly aid 60, so that the heat-conducting plate 30 terminates flush with the heat-conducting plate 30 in the direction of the holder 10 or is arranged offset in the fastening plate 50 slightly to the rear, that is to say in the direction of the assembly aid 60. Alternatively or additionally, it is also conceivable that, instead of or in addition to the heat-conducting plate 30, the light-emitting module 40 is also arranged and fastened on or in the fastening plate 50 (for example by means of the projections 52 and / or edge portions 54).

The assembly aid 60 preferably also has projections 61 pointing in the direction of the holder 10. These are preferably used for the lateral embracing of the mounting plate 50 and the holder 10 when it is placed on the mounting plate 50. This allows a correct positioning of the mounting plate 50 and holder 10 to each other and thus ensures that the mutually corresponding, corresponding screw holes 12, 51 are aligned.

According to a second case, it is possible to also insert the light module 40 in the passage opening 53, in such a way that the light module 40 comes to rest at least with the right and left edges 31 at corresponding edges 54 of the passage opening 53 and thus also in their Mounting position is fixed. Advantageously, the illumination module 40 with its area surrounding the illuminant 41 terminates flush here in the form of a circuit board 43 in the direction of the holder 10 with the heat-conducting plate 30.

Then, the holder 10 is placed on the thus formed three-part assembly 30, 40, 50, in such a way that the screw holes 12 are aligned with the screw holes 51.

Last but not least, the screws 3 are passed through the screw openings 12 and screwed with the screw holes 51 or, if they have no internal thread, with underlying screwing, such as nuts, so that the assembly 30, 40, 50 is fixed to the holder 10 , Thus, a complete module or a structural lighting unit is formed, which can be used in other parts, such as a light housing.

Previously, it was described that the luminaire assembly 1 is initially completely installed and can then be handled as a coherent element. However, it is also conceivable that the lamp assembly 1 (with or without Wärmeleitplatte 30 and / or mounting plate 50) is mounted directly on a lamp housing or the like, this preferably also corresponding alignment elements (comparable to the projections 61 and recesses 62).

In FIG. 2 shown coupling elements 70 are arranged in the holder 10 that they reach when placing the holder 10, preferably at the latest when fixing by means of fasteners (eg. Screws 3), with a corresponding one of the contacting points 42 of the light module 40 electrically in contact. In order to be able to supply the lighting module 40 with electrical energy, it is now possible, for example by means of connection pieces 2 designed as connecting lines, to be able to couple the coupling elements 70 with an external wiring, here in the form of the connection pieces 2. Ie. it is no longer necessary to couple the light module 40 with an external wiring before assembly or even need to solder. This simplifies the installation enormously. On the other hand, it is thereby possible to make the holder 10 resilient, so that it can move in relation to the mounting plate 50 in a predetermined amount, for example, away from the mounting plate 50 and to this. This resulting relative movement between the holder 10 and mounting plate 50 allows that when the mounting plate 50 is fixed, for example, in a lamp housing, vibrations that are transmitted via the lamp housing to the mounting plate 50, hardly or at least attenuated transferred to the holder 10. In addition, the coupling element 70 is designed to compensate for possible resulting relative movements of the lighting module 40 with respect to the holder 10. This is done in the simplest case in that the coupling elements 70, as shown later, press under bias on the contacting points 42 of the light module 40. Since the coupling elements 70 are arranged in the holder 10, this is readily possible. In addition, the release of a screw of the holder 10 can be avoided for the installation of the lamp assembly 1 safely and without additional components by the bias.

The holder 10 preferably has a recess 15 on its side facing away from the light-emitting module 40. This can be covered with a light-reflecting layer. Alternatively, the use of an additional reflector, which is inserted into the recess 15 and is also designed so that the light emitted by the bulbs 41 light is reflected by this use. It is the same Well conceivable that the recess 15 is formed by itself or by means of an inserted part with, for example, prism-like mirror elements that emit the light emitted by the bulbs 41 diffuse light into the room, so that a wide area in the room can be illuminated by means of a potentially punctiform luminous means.

Also, in the recess 15 - preferably before or in a possibly provided reflector (area) - be used an optical element such as a lens. The optical connection surface directly up to the exit of the light emitted by the light module 40 from the light assembly 1 can pass directly into specific reflectors, which can be fastened by way of example via a bayonet connection in the holder 10.

It can therefore be provided in the recess 15, the radiation characteristic influencing optical element.

FIG. 2 shows an exploded view of the holder 10 from the back in FIG. 1 and the mounting plate 50 increases in detail. For clarity and description reasons, the light module 40 and the heat conducting plate 30 are not shown.

In this illustration, the recesses 55 which project in the direction of the holder 10 can be seen particularly well on the side of the fastening plate 50 projecting in the direction of the rear side of the fastening plate 50, ie in the direction of the holder 10. Moreover, the projections 52 which are T-shaped in cross section can be seen here. The projections 52 buckle here in the direction away from the holder 10 side facing away something so that they include here the T forming lateral projections of the projections 52 to the holder 10 facing away from the other back of the mounting plate 50 a gap 56, so on this page have a certain distance. This allows, as explained above, both the heat conduction plate 30 with in FIG. 1 designated edges 31 and the light module 40 in the through hole 53 to record and fix fixed, for example by means of the edges 54, wherein the light emitting module 40 terminates flush with the pointing towards the holder 10 front side advantageously.

As can be seen, on the mounting plate 50 facing side of the holder 10, an optional spring ring 20 is arranged. The spring ring 20 has a passage opening 21 which serves for the passage of the light module 40 and the heat-conducting plate 30. Preferably, the spring ring 20 is designed so that it can be used in a corresponding receiving space 11 as a mounting portion of the holder 10, formed here by means of a circumferential corner-like recess, without protruding into the through hole 17 of the holder 10 and the receiving space 11. Here on two opposite outer sides of the spring ring 20 are close to the extension-like projections, which extend away from each other and each open into a section having a respective screw opening 22. The screw holes 22 are preferably aligned with the screw holes 12 when the spring ring 20 is placed on the holder 10. Furthermore, there are two projections 23 which extend away from one another and extend substantially perpendicularly to the projection-like projections, which project in the direction of holder 10 in their end regions. As a result, the paired protrusions 23 belonging to a respective screw opening 22 enclose a space forming a respective mounting recess 24.

With these projections 23 of the spring ring 20 is placed in corresponding engagement recesses 16 on the holder 10 and used, of which only the front are visible. The arranged in the region of a respective screw opening 22, mutually paired recesses 16 are mutually spaced, which is preferably slightly larger than the distance of the corresponding, mutually also paired projections 23 to each other. Furthermore, the pair of recesses 16 each include a socket-like projection 13. This makes it possible to clamp the spring ring 20 on the respective projection 13 by the paired projections 23 are pressed apart elastically. Ie. During assembly, the spring ring 20 is preferably placed on the holder 10 positively and / or non-positively, so that a resilient holder 10, 20 is formed, which itself is a separate structural unit, ie a module forms, which, as in FIG. 1 is shown, with the light module 40 and optionally also with the heat conducting plate 30 and the mounting plate 50 is mounted accordingly. This results in the above-explained advantages in terms of possible mechanical and thermal stresses that could act on the mounting plate 50 and thus on the entire assembly 1.

The spring ring 20 is partially to the holder 10 and can - if present - to the mounting plate 50 in the relaxation state, if not clamped between the holder 10 and mounting plate 50, have a distance. In contrast, the spring ring 20 is in other areas now on the mounting plate 50 and therefore has the holder 10 in the relaxation state at a distance

The spring ring 20 is preferably made of spring steel. Due to its known spring characteristic with respect to plastic, this material has the considerable advantage of being subject to only slight thermally influenced deformations even at the operating temperature and thus fundamentally permitting mechanically more stable operation over the entire service life of the luminaire arrangement 1. This material has the further advantage that it can not or to a much lesser extent than plastic in addition to a loss of optical property due to the delay caused by temperature effects itself, over time, to mechanical degradation processes in the spring steel material, caused for example by material embrittlement and like.

Furthermore, the coupling elements 70 are shown in this illustration. In the example shown, the connection sections 70 have an electrically conductive line section 71 which extends from an outer side of the holder 10 in the direction of the passage opening 17 or in the direction of the contacting points 42 of the lighting module 40. At its end facing the through-opening 17, the coupling element 70 opens into a connection section 74, which in the simplest case is formed by means of a stripped-off line end. This line end or the connection section 74 is designed so that it extends in the direction of mounting plate 50 or light module 40, ie here upwards with respect to the holder 10, that when the light module 40 is placed, its corresponding contact point 42nd with an associated terminal portion 74 of a corresponding coupling element 70 electrically comes into (touch) contact. The line section 71 opens at its end facing away from the passage opening 17, preferably in another connection section 73 which is accessible in the direction of the non-designated outer side, which faces away from the passage opening 17. For this purpose, the holder 10 preferably has a coupling element 14 in the form of a groove-like recess, passage opening or other structure, which makes it possible to preferably positively and / or positively receive the respective coupling element 70 in the holder 10 in a fixed manner. From the coupling elements 14, 14 only the left one is visible. The terminal portion 73 may be formed in any shape. Here it is designed as a bronze contact and advantageously at least partially provided with a hard gold coating. However, it can also be designed, for example, as a soldering contact, screw-type contact or in another form, which makes it possible to be able to electrically couple the coupling element 70 with a corresponding external electrical wiring.

Each terminal portion 73 is preferably disposed on a fixing portion 72 of the coupling member 70. The attachment portion 72 is formed here as a sleeve and preferably arranged in the respectively associated coupling element 14 of the holder 10 positively and / or non-positively.

The invention is not limited to the above-described embodiment. The above-described lighting module 40 may have any type of light sources, for example the aforementioned but also halogen lamps and the like. Furthermore, the lighting module 40 may be provided with a driver circuit which is arranged, for example, on a rear side of the lighting module 40 facing the fastening plate 50.

The luminaire arrangement 1 according to the invention does not necessarily have to have a heat-conducting plate 30 or mounting plate 50, as long as the unit comprising holder 10 and luminous module 40 can be formed by means of the touch contact according to the invention.

The mounting aid 60 may be replaced by another part or holding element, for example a driver housing, a lamp housing, a holding frame, a heat sink, a heating element or a mounting element or combined with such a part. In the case of the driver housing, this preferably has the driver circuit for the lighting module 40 or its lighting means 41. A combination of the aforementioned holding elements with the luminaire arrangement according to the invention can also be referred to as a luminaire according to the invention. For an optimized heat dissipation, a surface contact should be provided between the luminaire arrangement 1 (for example the luminous module 40, the heat-conducting plate 30 or the mounting plate 50) on the one hand and a heat dissipating structure of a luminaire on the other hand.

If the part is a people's housing, the module 30, 40 formed above, for example or advantageously via the fastening plate 50, can be fastened therein. If this part is replaced by a support frame, the light module can be used, for example, in a 55 mm insert a conventional socket, for example, for a power outlet.

If this part has a heat sink, or if it forms such a heat sink, this can be used for the effective heat dissipation of the entire module. For example, the heat sink may have external cooling fins.

The heat conducting plate 30 and the mounting plate 50 may also be integrally formed. Furthermore, they may consist of different materials and be formed for example by means of coextrusion.

The resilient embodiment of the holder 10 may be realized instead of the use of a spring ring 20, for example by means of the holder 10 itself trained structures. This can be achieved, for example, by means of spring projections, which preferably project freestanding in the direction of the fastening plate 50 and are resiliently pressed back in the direction of the holder 10 when the fastening plate 50 is fastened. The resilient design has the advantage of tolerance compensation at a pressure on the light module 40. Also, so that a loosening a possible screwing can be avoided.

The resilient training can of course also be realized on the mounting plate 50. The spring ring 20 could for example be replaced by means pressed into the holder 10 spring elements, such as spring rings, or combined with these.

Alternatively, for example, the use of elastic, for example made of rubber elements, which are arranged between the mounting plate 50 and holder 10 and are compressed by means of the screws 3 to some extent. The coupling element 70 or its connection section 73 can also be held down by the spring part 20 in the direction of the holder 10. This can be done, for example, that the screw opening 12 has a larger diameter than required for the screw 3. In the resulting space between the holder 10 and screw 3 is the mounting portion 72, at least on a side facing the spring ring 20 from a electrically insulating material and also has a through hole, which is aligned with the screw hole 12. Through this passage opening then the corresponding screw 3 is passed. The fastening section 72 advantageously isolates the associated line section 71 from the screw 3 and the screw openings 12, 51.

The mounting plate 50 may have any other shape instead of the plate-like configuration. It may, for example, form or have the aforementioned attachment plate 50 and may have other structures such as the retention element.

The holder 10 may have at its side facing the mounting plate 50 side corresponding to the recesses 55 points projections which extend in the direction of the mounting plate 50 and engage in the mounting in these recesses or recesses 55. Thus, a positioning of the mounting plate 50 with respect to the holder 10 is possible, so that mounting errors can be reduced. In the example shown, the depressions 55 are rotationally symmetrical in such a way that the fastening plate according to FIG FIG. 1 can be mounted in the position shown there or rotated by 180 °. But it is equally possible that the recesses 55, for example, only in the top FIG. 1 are formed. In order nevertheless to achieve an alignment in the arrangement mounting plate 50 and holder 10, the mounting plate 50 can be mounted only in a single position with respect to the holder 10. In other mounting positions, in which the mounting plate 50 is rotated by a certain angle about the mounting direction, which is here defined by the Aufschieberichtung on the holder 10, the mounting plate 50 would either have to the holder 10 at a distance, so that for example one of the screws 3 can no longer be screwed, or the screw holes 12, 51 would no longer be aligned with each other or arranged angled to each other.

Thus, a torsion-proof assembly is possible. This can of course also be realized between the mounting plate 50 and the heat-conducting plate 30 or light-emitting module 40, in which corresponding structures are formed. This can be done, for example, in that the passage opening 53 is asymmetrical with respect to a center axis of the attachment plate 50, so that the illumination module 40 and the Wärmeleitplatte 30 can be accommodated in the through hole 53 only in a single mounting position.

The coupling element 2 is not limited to the described lines. For example, the coupling element 2 may be realized by means of contact pins arranged in a luminaire housing, resiliently mounted in the direction of the holder 10, which are pushed back by the holder 10 when the holder 10 (with mounted elements 30, 40, 50) is inserted into the holder Snap back coupling elements 14 and thereby electrically get in contact with the corresponding coupling elements 70 in the holder 10 in contact. Ie. the coupling between the coupling elements 70 and the external wiring is not limited in any particular way.

For example, the connection sections 73 can be realized by means of one or more plug contacts, for example in the form of a two-wire connection socket. Im in FIG. 1 example shown could, if there is only one coupling element 70, for example, the right in FIG. 1 is accessible, a line in the holder 10 to be laid on the opposite side and projecting free-standing on this opposite side with respect to the passage opening 17 in the direction of passage opening 17. This would continue the already described light module 40 can be mounted.

The contacting points 42 of the lighting module 40 are also not limited to the embodiment shown. They may also be formed in any shape, but are preferably shaped so that the light module 40 remains flat. But it is also possible, for example, in the direction of holder 10 protruding coupling contacts, such as spring contacts, provide, which are aligned with a through hole as a coupling element 14 of the holder 10, when used, so that a line 2 through the through hole 14 through with the spring contact in electrical contact arrives. In the case, the holder 10 preferably has corresponding recesses in which a respective one of the spring contacts is accommodated. Alternatively, the board 43 on preferably mutually away facing edges contacting points 42, which face each other in the mounting position in the direction of an associated terminal portion 73. If the respective connection section 73 is formed as a spring pin, this is spring-biased at the associated contact point 42 electrically couple in plant.

According to the invention, therefore, a frame, preferably a spring frame, provided in the form of advantageously resilient holder 10, which in addition to its resilient property during installation - ie by tightening the screws 3 resulting, desired deformation and thus bias of the holder 10 as a frame body - with frame body side provided contact elements 70 is provided to meet the problem mentioned above. The frame or holder 10 according to the invention thus combines, on the one hand, the positive property of the flexible support and thus of the compensation of the deformation also resulting from temperature effects and, on the other hand, the contacting with the light module or support, which is directly and without soldering during installation, ie assembly. If present, their (LED) board 43. For this purpose, for example, in the spring frame 20, a base contact element in the form of the coupling element 70 for making contact with the light module 40 and thereon either integrally or additionally provided elements for receiving a cable contacting can be provided.

The frame or holder 10 according to the invention is used for the finished module 10, 20, 30, 40 as a central connecting element, which in addition to the light module 40 also other elements such as heat sink / housing, reflectors and other elements usually provided with corresponding optics may be provided can.

This is exemplified by the aforementioned mounting aid 60 or a holding element, which serves as an alignment for the assembly of the module 10, 20, 30, 40. This aligning element thus formed has corresponding openings and / or the like, which cooperate and match with comparable or corresponding elements of the resulting LED holding module, so that by simply placing the individual elements in stages, an automatic alignment of these can take place. By simple subsequent screwing, the lighting arrangement 1 according to the invention can thus be easily assembled, for example, as an LED module holder.

In addition to the aforementioned fasteners, of course, all other non-positive and positive fasteners are possible, such as locking, jamming, bonding, etc.

Due to the luminaire arrangement 1 according to the invention there is no particular soldered wiring between light module 40 and coupling element 2 during assembly. This makes it possible to mount the luminaire assembly 1 by means of stacking of the components 50, 40, 10, 20, for example, using the mounting aid 60 in particular automated ; Sensor technology for the cabling is not required.

The simple structure allows a cost and / or complexity reduction and thus a (mounting) error reduction. The solderless contacting or the possible use of poke-in contacts simplify assembly further. Assembly can be done in simple, well-defined steps that reduce poke-yoke features and visual cues and reduce the chance of errors compared to standard holders.

In addition, the luminaire assembly 1 allows standardization or standardization, since with the luminaire assembly 1 a wide variety of lights can be realized. The luminaire arrangement 1 can be used in specific lighting technology, while maintaining a compact design, possibly with light-directing optical surfaces up to the edge of the exit of the light emitted by the light-emitting module 40.

As a result, the invention provides a particularly simple solution to produce a lighting module as a structural unit, which can be easily used in retrospect in existing systems, such as a halogen lamp or mounted and can be electrically coupled with a wiring in retrospect. The result is a simple modular system. The advantages are in particular the simple and less error-prone to be mounted luminaire assembly 1 and their integrability in lights, secure contact of the light module 40 to the outside, the simple and secure attachment of the individual parts of the lamp assembly 1 to each other and easy connectivity to a specific lighting technology including reflector attachment, and with very compact dimensions of the lamp assembly 1. Due to the mechanically and thermally stable by the lamp assembly 1 system, the cost of errors can be reduced.

In summary, the holder 10 thus provides the function of cabling the lamp assembly 1 to the outside and the attachment and advantageously positioning a photoconductive element such as a reflector, holding element such as a housing, the heat plate 30 and the mounting plate 40 and the light module 40, with respect to the The heat module 30 realizes the heat dissipation from the light module 40 to a heat sink and / or housing, on or in which the light assembly 1 is integrated or mounted.
