Description

The invention relates to a luminaire, in particular a linear luminaire, in particular a continuous line luminaire, designed for releasable connection to a support rail connected to a developer for receiving and guiding a wiring, in particular a through-wiring. The continuous-line luminaire comprises a device carrier which can be detachably connected to the mounting rail with a device carrier top designed for the arrangement of electrical and / or electronic components for the continuous line luminaire and a device carrier underside for arranging an LED luminous means for generating a luminous flux radiating in a direct light direction, preferably arranged on the top of the device carrier electrical components, at least one arranged on the device carrier base LED module, arranged in the direct light direction in front of the at least one LED module optics formed for the light control of the luminous flux to realize a visual task to be implemented with the continuous line light.

In addition, the invention relates to a manufacturing method for a luminaire, in particular a linear luminaire, in particular designed as a continuous luminaire, comprising at least as lighting components optics, an LED module, a device carrier and a driver equipped with electrical and / or electronic luminaire components, comprising the following method steps: Connecting an optical system with at least one LED module in a desired optical target position, connecting the thus formed optical system with a device carrier and connecting the driver to the device carrier.

The continuous-line luminaire is an independent luminaire, which is thus able to function independently, ie can be fed with a supply voltage for individual operation. In addition, however, it is also possible to connect several continuous-line luminaires with one another to form a so-called lighting band system, which can be made e.g. hanging from a ceiling or can extend to a ceiling over several meters, the individual band lights are arranged with their respective end faces adjacent to each other under a blanket. Such a lighting system normally comprises a continuous mounting rail, wherein the individual juxtaposed components of the mounting rail receive the through-wiring for the lighting system and preferably comprise connectors or couplings for connecting the individual mounting rail elements with each other.

State of the art

Existing continuous line luminaires comprise a mounting rail which can be fastened to a ceiling, a building support or the like, which is made of e.g. can be bolted directly to the ceiling or suspended from the ceiling via chains or ropes as part of the installation in a suspended ceiling. The mounting rail absorbs the through-wiring, so it is connected to the supply voltage. The support rail itself is usually formed as a folded sheet metal profile having a substantially channel-shaped or channel-shaped geometry, which is closed at the top in the installed position and has a lower mounting rail opening in the installed position. In this opening a device carrier can be used or connected to the mounting rail. Preferably, retaining springs are provided on the device carrier for this purpose at certain predefined intervals, which releasably fasten the device carrier to the mounting rail. The usually consisting of folded sheet metal mounting rails and the equipment carrier form a closed geometry in the assembled state, usually the gutter-shaped mounting rail is closed in the installed position on the underside by the equipment carrier lid-like.

On the substantially flat device carrier, electrical luminaire components, for example, are preferably arranged on the top of the device carrier. Plugs, terminals, wiring and a driver, often referred to as LED converter (LEDC) or ballast, for converting the mains current into a suitable supply current for the respective lamp. On the underside of the equipment support, however, are usually nowadays especially as LED modules (often abbreviated as LEDM) trained bulbs mounted and in turn an optical element for directing light and light bundling a generated by the LED modules luminous flux for the realization of a defined Sehaufgabe. The LED module and the optics are usually designed as plastic parts.

This known training already allows a very efficient and adaptable design of continuous line lights, but also has certain disadvantages because of the different board thicknesses or strengths of the LED modules or their support plates. Unfortunately, it can never be ruled out that the carrier plates of the LED modules have different thicknesses, ie material thicknesses, which can lead to problems during assembly. If the LED modules are thicker than the standard thickness intended for assembly, gaps can occur laterally between the device carrier and the lamp cover, which laterally overlaps the LED modules in the installed position, leading to leaks. This is particularly disadvantageous in lights higher Degree of protection, which must therefore be air-tight and moisture-proof. To circumvent this problem, it was considered to enclose the LED module and the optics again in another capsule enclosing these two components in the installation position, which then represents another component, which is sometimes undesirable. In addition, small animals, such as flies, can enter the gap. On the other hand, if the board of the module is too thin, tensions between the optics and the LED module may occur when tightening the fastening screws, which adversely affect the life of the components or even destroy them during assembly. Regardless of the problem of the different strengths of the support plates of the LED modules, the production of existing continuous line lights is relatively expensive, since the components must be turned and rotated several times during assembly, which is not unproblematic especially in an automated or automated as possible production.

Technical problem / task

Based on this prior art, the present invention seeks to at least partially avoid these disadvantages and in particular to provide a continuous-line luminaire, which has the Schutzartkonforme tightness even if different thickness or strong LED modules are used. In addition, the light strip light should also be easy to manufacture, especially in the context of automated production.

invention

According to the invention this object is achieved in a continuous line luminaire of the type mentioned already by the features of the independent device claim and the independent method claim.

In a continuous-line luminaire of the type mentioned at the outset, this is already achieved insofar as the device carrier and the optics comprise plastic or are essentially formed therefrom and a material-locking connection of the two at a connection point provided between these two components, ie between the device carrier and the optic Components is realized.

In a manufacturing method, this object is also achieved in that the lamp components, optionally exclusively along a mounting direction without rotation in the series first connecting the optics with at least one LED module in a desired optical target position to form the optical system, then arranging the device carrier the optical system and then placing the driver on the equipment carrier. The thus arranged in the respective desired position lighting components are finally materially connected together and fixed in position in this desired position.

The integral connection can be realized in any convenient way, e.g. by gluing, fungaling (hot-forming riveting or ultrasonic riveting) or melting. Ultrasonic welding has proven to be particularly advantageous for the realization of particularly low throughput times in the production because less than one second is required for the joining or fixing of the lighting components. For this purpose, a so-called energy directors or a welding geometry with a material thickness of 2 - 4/10 mm is preferably provided at the joint between the joining partners on one side, which realizes the connection during welding. This allows so far for the first time a completely automatic production, the individual components are connected by installation in position lower components, in particular the optics or the lamp cover exclusively along the mounting direction from bottom to top, without the individual components are rotated or turned have to. The lighting components can thus be set up in the assembly direction constructive succession and then positively connected by ultrasonic welding in the respective desired position without further handling. The manufacturing method according to the invention thus enables the assembly in a single mounting direction without rotation or other and handling the continuous line lighting, starting from the lowest component, in particular the optics, the top component, the equipment carrier or other lighting components, e.g. the carrier plate, which is why this manufacturing method is particularly suitable for automated production. This mounting direction thus preferably extends in the distal direction upward from a lower mounting plane serving as a reference plane.

The formation of the device carrier made of plastic and its connection with other lighting components by means of a cohesive connection, in particular by means of ultrasonic welding, has numerous advantages. Obviously, this embodiment is completely without additional sealing material, so that in this respect no grooves or sealing grooves must be provided for receiving seals. Furthermore, according to the invention, luminaires virtually always fulfill a high degree of protection of IP 65 and higher. The need for connecting means such as screws, clamps, springs and the like is completely eliminated. Also, connecting means are no longer visible, which can significantly improve the aesthetic appearance of the lamp.

In particular, polycarbonate or PMMA have proven to be particularly suitable plastics for the production of lighting components, as these are widely available, inexpensive and easy to handle.

In a basic version, the equipment carrier may e.g. be formed as a circumferentially closed, substantially flat frame member having a central, formed by the device carrier module opening for receiving the at least one LED module, preferably several in the lamp longitudinal direction frontally adjacent to each other in the module opening insertable or inserted LED modules having.

This configuration makes it possible, for example, to use different height or LED modules with different height LED boards in the same equipment rack or above the LED modules to arrange a cooling plate or cooling plates, which significantly improve the performance of the lamp. Anyway, a particularly simple installation in the context of the initial installation, but also a repair is possible because of this spring elements, because this allows the removal of the LED modules from the lamp housing without complete disassembly.

A preferred embodiment provides on the device carrier provided, preferably bridge-like design spring elements which extend in the installed position bridge-like and resilient over the module opening and fix the position or the LED modules in the optical target position, in which these preferably along the lamp longitudinal axis extending fixing in this position optical target position is positioned. These spring elements are thus designed to fix in accordance with the installation situation, the at least one LED module in the optical target position, so this press in installation position in the desired position. But this is also possible by changing the spring elements with different spring characteristics and spring travel and a redesign of the lamp for different installation situations by using different LED modules.

Preferably, a plurality of such spring elements at defined intervals along the device carrier longitudinal axis bridging this module opening or provided over.

In a further development, these spring elements or spring bridges can also be latchably formed on the device carrier, so they are designed for retrofitting and conversion.

By appropriate design of the plastic device carrier may be incorporated in these different geometries, so also, for example. Housing walls or housing parts may be provided which receive or enclose or demarcate electrical components. This is preferably done by channel walls, which are formed in particular centrally on the top of the device carrier and which can define a receiving space for electronic lighting components between them. Since electrical components in the manufacturing process in the walls or in the equipment carrier can be integrated, the solution of the invention is also MID-compatible, which of course allows much greater degrees of freedom than metal carriers, where this is not possible.

By welding the components to the joints or the joint, in particular at the joint between the optics and the equipment carrier in the system also exists a large tolerance to different thicknesses of the LED modules, which usually between a thickness of 1 and 1.6 can fluctuate.

It is thus also possible that the equipment rack is first assembled as a precursor of different equipment carrier components and these are interconnected, this modular equipment rack is then placed on the lamp cover and the components are materially interconnected or all components are connected separately and in the respective Target position then firmly bonded together in the desired position captive.

The device carrier according to the invention can thus also have much more complex geometries than a component folded from sheet metal as in the prior art. In addition, fastening elements, such as latching strips or engagement strips or else housings for accommodating electrical components can be integrated in or on the device carrier.

The device carrier preferably defines an at least partially planar mounting or fastening plane formed on a lower end in the installation position for the arrangement of the at least one LED module, possibly reflectors or optics in the optical nominal position. Structures may now be provided at this mounting plane, both upwardly and downwardly extending, in particular integrally formed, e.g. preferably transversely extending to the mounting plane a channel or a stiffening structure.

The stiffening structure may e.g. comprise one or more stiffening ribs or stiffening ribs, e.g. web-like formed on the equipment carrier.

Embodiments provide that the height of the stiffening structure to the width of the device carrier from outer edge to outer edge is 1: 2 to 1: 4.

These stiffening strips are preferably designed as longitudinal strips extending in the device carrier longitudinal direction for increasing the longitudinal rigidity. At the front ends of these longitudinal strips can be connected via transverse strips, particularly preferably to form a circumferentially closed stiffening frame, which gives a particularly high stability.

Preferably, the stiffening structure extends on the upper side of the device carrier substantially transversely extending to the mounting plane of the device carrier. The stiffening structure is further preferably integrally formed on the device carrier.

In addition, fastening means may be formed on the stiffening structure, in particular latching means for detachable connection with a joining partner, e.g. the mounting rail.

The device carrier may also comprise, in particular reflector surfaces formed on its device carrier underside, e.g. curved or inclined reflector surfaces or a partial reflector surface which surround the LED module laterally. Preferably, these are formed on the device carrier base. Preferably, these reflector surfaces are formed as projecting from the mounting plane of the device carrier reflector surfaces, in particular as the optical center of an adjacently arranged LED module towards inclined reflector surfaces, the height of which increases along the longitudinal axis of the optical axis extending in height to the outside.

The device carrier itself, however, can also have a modular design and comprise a plurality of device carrier modules which can be connected to one another or are connected to one another. He can e.g. only two end face on a joint adjoining end or end modules include. As required, extension modules can also be arranged between the end modules, with which device carriers of any length can be created individually for each customer. This reduces the storage costs for different variants, because now equipment carriers can be assembled as needed from Endmodulen and extension modules as needed. Preferably, the connecting or joining points between the modules are formed in the manner of a miter, but not at a corner, but with an overlap in the lamp longitudinal direction, wherein the overlap in this direction increases from the device carrier lower end to the top of the equipment carrier, ie a module with a slope at the joint on a complementary slope of the joining partner rests so that a closed uniform structure is created.

Embodiments provide a module opening for the receiving insert of the at least one LED module in the optical nominal position on the device carrier. Preferably, this module opening is formed centrally in the longitudinal extension direction in the equipment carrier, so that one or more LED modules can be arranged with their front-side head ends adjacent to each other in the module opening. Thus, one or more LED modules can be inserted into this module opening or placed on it and fixed in position in the module holder on the device carrier.

A particularly stable embodiment provides that the device carrier with its mounting plane surrounds the central module opening like a frame. In or on this module opening, the at least one LED module can be used both from the device carrier underside and from the device carrier top side.

At the joining partners, in particular at the equipment carrier, the module opening may be formed with bridging or spanning fixing elements for the LED modules, e.g. formed as one or more spaced in the longitudinal direction of the lamp elastic retaining springs.

Another embodiment provides that this module opening is bridged bridged by a bridge on the top side to form a module channel, in which the at least one LED module from below and above can be used.

On the inside of this module channel structures can now be formed, such. One or more paragraphs in which the LED modules and additional components can be used in different positions.

Preferably, the module channel on the side walls comprises one or more stages to form at least one abutment edge or abutment shoulder for the at least one LED module in the module channel with a space above it for receiving further components. For example, a power-increasing cooling plate or additional cooling plate can be arranged above the at least one LED module in the module channel to increase performance or better heat dissipation.

The module channel can thus be configured as an LED channel, that is to say be configured as a channel-shaped, closed recess, into which one or more LED modules in the optical Sollposition are receiving used, preferably in the longitudinal direction of the front side adjacent to each other to form longer linear lamps.

The luminaire structure can be further simplified by the fact that a channel or receiving space or housing parts are formed on the device carrier, which can also be designed differently in the different device carrier modules.

For example, in the end or end modules, a preferred embodiment provides walls extending parallel to one another for forming a channel formed on the top side on the mounting plane, which may also be made higher than e.g. in the preferably centrally arranged extension modules. This channel can serve in particular for receiving the electrical or electronic luminaire components, but also serve other components. Thus, the device carrier or the walls of the channel form the housing for receiving electrical components or components. Thus, for the LED converter (often abbreviated to LEDC) driver or ballast no separate housing must be provided, but rather only by the inventive design of the device carrier only a plate-shaped and designed as a support member for the electrical and / or electronic components carrier plate have, on which preferably the electrical components are pre-assembled. During assembly, this support plate can now be placed on the equipment carrier or in the channel and also connected to it in a materially cohesive manner, again without rotation of the components. Thus, also equipped with electrical components carrier plate can be placed in the mounting direction on the equipment carrier and positively connected to the device carrier in the desired position, in particular again by ultrasonic welding.

The housing-less design of the driver with only a support plate allows a more compact design than known drivers, which usually have a metallic housing. In fact, according to current standards, printed circuit boards and electrical components within the driver must have certain minimum distances from the metallic housing. This is no longer necessary in the embodiment of plastic according to the invention, so that overall less space is required for the driver, so this can be more compact, but in any case can be integrated into the device carrier, the device carrier then preferably forms the housing for the driver, especially through a canal or a channel. As a result, clearances and creepage distances are much lower and less critical than with sheet metal equipment carriers

For the realization of a tool-free mounting as possible, the device carrier plug contacts for realizing the Primärkontaktierung (connection of the input side of the LEDC with the line network) and / or the secondary contacting (connection of the output side of the LEDC with the at least one LED module (LEDM)) include.

For example, the plug contacts on the carrier plate, e.g. comprise a primary contact for the Primärkontaktierung on a mounting position in the upward direction carrier plate top and on a device mounting base directed downward in the installed position a secondary contact for the secondary contacting.

Both the primary contact and the secondary contact preferably comprise one or more contact pins, which are designed to realize an electrical connection in the installed position with the electrical joining partner. This electrical joining partner may e.g. be formed as a bus bar with one or more lines (e.g., 7). The primary contact may e.g. comprise a plurality of primary fingers, which can be inserted in the installed position in corresponding lines in a bus bar arranged in the busbar.

Also, the secondary contacts may be formed as contact pins which spaced from each other from the support plate protrude downwards and engage in mounting position in terminals of the LED modules to supply them electrically with the generated by the LEDM Nutzstrom.

A particularly secure embodiment comprises contact guides formed on the device carrier which support these contact pins, e.g. completely enclose and thus electrically secure.

Thus, by the carrier plate in the context of a through-mounting immediately the secondary contacting can be realized during assembly, without further wiring is required.

Embodiments provide fastening means provided or integrated on the equipment carrier. These may e.g. Comprise springs which span a receiving area. If e.g. an LED module inserted into this receiving area, these springs press e.g. the LED module against contact surfaces of the receiving area.

In other embodiments, the fastening means comprise at least one latching, holding or clip strip for connecting the device carrier with other joining partners, e.g. with the mounting rail.

Preferably extending laterally on the device carrier in the lamp longitudinal direction Clipleisten are provided, which have a complementary formed to a joining partner locking edge, which is connected to a joining partner, such as a support rail, latching and releasably connectable.

The electrical connection between two preferably frontally adjacent device carrier modules of a device carrier to form an electrically continuous device carrier is accomplished in the preferred embodiment by jumpers, which project into the respective component projecting conductor pins which protrude at the joint of the material and with a bridge the joint be interconnected electrically with each other.

Other embodiments provide on the equipment carrier before a stiffening structure, which is preferably integrally formed on the equipment carrier. The stiffening structure may e.g. extending substantially transversely to the lower, in the installation position, in particular horizontally extending light-emitting surface extending stiffening strips, which may have a height of 1 to 60 millimeters and thus can realize the required longitudinal stiffness of the lamp alone by the equipment carrier.

Preferably, this stiffening structure is formed on the outer edge of the device carrier and particularly preferably formed as the bending stiffness of the device carrier increasing stiffening frame, in particular formed on the outer edge of the main plane of the substantially flat device carrier.

The connection means for connecting the device carrier to the support rail or other luminaire components may be formed on the stiffening structure, e.g. in the form of a latching structure or the part of a latching structure for connection to a complementary formed joining partner, e.g. comprising an edge or a projection, which in the installation position is releasably connectable to the complementary formed mating partner, e.g. by latching.

Preferably, the length of the equipment carrier is adapted to the length of the LED modules used, so that a LED module or a certain number of LED modules can be attached to a device carrier. To achieve a particularly high degree of modularity, however, it is also possible for an LED module to extend over two interconnected device carriers or device carrier modules.

It is within the scope of the invention, instead of or in addition to the at least one LED module to provide a sensor module for the light control, which is preferably identical to the LED module, so that LED modules and sensor modules can be combined and exchanged arbitrarily are.

In addition, the invention relates detached from the lamp itself, but also an optical system for use in a lamp, in particular a linear luminaire, preferably designed as a continuous line luminaire with a device carrier or a lamp housing designed for the arrangement of electrical lighting components and designed as an LED module bulbs for Generation of a luminous flux radiating in a direct light direction as well as an optics arranged in front of the LED module in the direct light direction for generating a desired light distribution curve for illuminating a visual task.

In the case of such luminaires, it is necessary in the prior art to realize a modified light distribution curve, e.g. to adapt to a changed visual task, e.g. for changing from a strongly focused direct light to a more broadly radiating light, e.g. To illuminate a sales area, to install different optics for these different visual tasks and desired light distribution curves. This requires a high number of variants of the optics and can sometimes be relatively complicated.

In this respect, the invention further deals with the further technical problem, and indeed completely separate from the first technical problem to avoid these disadvantages at least partially and to provide a luminaire, in particular a strip light whose luminous characteristic, ie light distribution curve (LVK) is easy to change.

In order to solve this second technical problem and to reduce the number of variants, the second invention proposes that spacers are formed between a designed as an LED module bulbs for generating a radiating in a direct light direction luminous flux and a front of this light source in the direct light direction optics the rotation of the optics in at least two different installation positions, these spacers interact so distantly with the LED modules, that the at least one LED modules occupies a first distance to the optics in a first Ersteinbaulage, and in a second, different from the first Ersteinbaulage Second mounting position occupies a different second distance from the first distance. Preferably, the first distance is smaller than the second distance.

At the upper, ie the distal ends of the spacers, preferably at least two differently sized supports are formed which cooperate in the respective installation position with corresponding recesses of the joining partner, in such a way that the installation of the joining partner is possible only in the respective optical target position corresponding to the respective orientation , This can be done, for example, by forming a lower, more proximal located, wider Erstauflagers and a relative to this Erstlauflager distally upwards and compared to the Erstauflager also smaller Zweitauflagers.

The correspondingly formed joining partner of the optical system, preferably the at least one LED module, have first and second recesses corresponding to the first or second supports and offset relative to one another on the LED module, the first recesses being relatively mating with the larger first supports for corresponding pairing are formed larger than the corresponding to the second supports second recesses. This implements that the larger Erstausnehmungen in the Erstausrichtung the LED modules can rest only on the wider Erstauflagern, whereby the respective LED module is located lower and closer relative to the optics, whereas in the preferably rotated by 180 degrees to the Erstausrichtung Secondary alignment only the smaller second recesses rest on the smaller secondary supports, so that the LED modules are higher in relation to the Erstausrichtung.

Thus, by simply rotating the LED modules about the central pivot point with the same optical system comprising optics and at least one LED module, two different optical systems can be realized. Preferably, the height difference between the first and second orientation of an LED module in relation to the optics in the range of 0.3 to 2 mm, more preferably 0.7 mm.

The preferably rod-shaped spacers have a proximal attachment end, with which they are connected to one of the component of the optical system, ie with the equipment carrier or optics, and extend first from the respective attachment end distal to the Erstauflager and then with geometric reduction further down to the smaller secondary support and possibly again reduced in size to form a centering.

To reduce optical interference, it is expedient to arrange each two spacers in the transverse direction of the lamp spaced from each other preferably at the same height along the longitudinal axis of the lamp to form spacer pairs. Of these spacer pairs more along the lamp longitudinal axis are provided, which are preferably equidistantly spaced from each other. It should be noted that the spacers need not necessarily be arranged in the transverse direction of the lamp opposite at the same height in the lamp longitudinal direction. The spacers are preferably provided on both sides by an LED module arranged on the optical lamp longitudinal axis, and particularly preferably in pairs, laterally enclosing this LED module.

Embodiment provide the arrangement of the spacers spaced from one another in the longitudinal direction of the lamp in order to avoid optical interference. Particularly preferably, the spacers are integrally formed on the particular consisting of a transparent plastic lamp cover inside, so protrude on the inside of the lamp cover. Manufacturing technology, it is advantageous if the spacers are integrally formed on the optical component. Preferably, the mounting positions are offset by 180 degrees in relation to each other, so that the optics in the two mounting positions is thus rotated by 180 degrees to each other. This basically allows two different light distribution curves to be realized with the same look. Possible combinations are e.g. DA Narrow - DA Wide; Asymetric Narrow - Asymetric Wide; Narrow - Very Narrow.

For the skilled person it is understood that the inventive design is not limited to linear luminaires and continuous line lighting, but can be used for the simple production of all lights.

1 shows an isometric longitudinal view of a strip light according to the invention 2 from below, in this case composed of four light band modules 4 . 6 . 8th . 10 , each having a rectangular, box-like geometry and with their inside, adjacent end faces are frontally fastened together to form the longitudinally extending continuous line luminaire with a length of about 1.5 m.

The light band modules 4 . 6 . 8th . 10 are more accurate in the isometric top view of the continuous line luminaire 2 according to 2 to recognize. Accordingly, the taillight includes 2 at the front end modules 4 . 6 and between the front ends arranged and about twice as long extension module 8th ,

3 shows an enlarged cross section through the front end module 4 along the line III - III according to 2 , The end module consists of a designed as a plastic injection molding device carrier 12 which defines at its lower end a main plane or mounting plane, which is primarily designed for mounting or mounting of LED modules 14 extending along the center of the equipment rack 12 along its entire length. For this purpose is centered in the equipment carrier 12 a two-stage module channel 12.1 provided, which is closed, at least in the end modules 4 . 6 , This module channel 12.1 is geometrically adapted to the size of the recorded LED module 14 so that the LED module 14 So with its LED board or carrier plate in the module channel 12.1 can be used, so that the LED module 14 about half in this module channel 12.1 is included. The module channel 12.1 can thus help reduce the height by appropriate training, because the LED module 14 no longer has to be screwed flat on a metal equipment carrier, but now in the equipment rack 12 can be included.

On the top of the main plane of the device carrier 12 is in the region of the outer edge of a circumferentially closed stiffening frame 12.2 formed and offset laterally outward from the central module channel 12.1 Two are also transverse to the horizontal plane 12.5 parallel to each other extending channel walls 12.3 . 12.4 molded, which is slightly stronger than the stiffening frame 12.2 are formed, about the same are offset inwards, but together with the stiffening frame, the longitudinal rigidity of the equipment carrier 12 essentially define and thus the main level or horizontal plane 12.5 altogether more filigree.

The height of the stiffening frame 12.2 is in this embodiment, slightly more than a third of the width of the device carrier, ie the length of the horizontal plane 12.5 from outer edge to outer edge.

On the top of the canal walls 12.3 . 12.4 is a carrier plate 16 attached, which has on its underside various electrical components, such as a control gear, which thus in through the two channel walls 12.3 . 12.4 projected channel so that this channel is the housing for these electrical components. The carrier plate 16 is also cohesively with the upper ends of the channel walls 12.3 . 12.4 connected, in particular by ultrasonic welding.

On the bottom of the horizontal plane 12.5 of the device carrier 12 is on the outer edge again cohesively a translucent optics 18 attached, with their outer edges to the outer edge of the device carrier 12 or its horizontal plane 12.5 closes and then tapers slightly inward down to the lower light exit surface 18.1 extends in the middle with a customized to the particular application collimator lens 18.2 is formed, which of the on the LED module 14 arranged LEDs bundles or directs.

4 on the other hand shows a cross section through the end of the end module 4 along the line IV - VI according to 2 So, where it goes to the extension module 8th borders. At this point, the top of the module channel points 12.1 integrally formed and spaced from each other two hollow cylindrical contact guides 12.6 . 12.7 on, which serve for the enclosing receiving pins, which the secondary contacting of the power supply of the LED module 14 realize. On the one or more LED modules 14 are positioned accordingly contact terminals 14.1 . 14.2 provided, in which the on the support plate 16 downwardly projecting and acting as a secondary contact pins 16.1 . 16.2 are pluggable. These pins 16.1 . 16.2 , are simply plugged through the contact guides 12.6 . 12.7 guided inserted into the contact terminals 14.1 . 14.2 to realize the electrical connection of the LEDC with the LEDM.

As from the isometric longitudinal section according to 5 can be seen, as a contact element for the realization of the primary contact of the LEDM with the mains voltage on the top of the carrier plate 16 a comb-like contact comb 16.3 arranged, which engages in installation position with the individual fingers of the contact comb in individual lines of a busbar, which is arranged for example in the mounting rail above the equipment carrier 12 ,

As a fastening means comprises the equipment carrier 12 an outside of the stiffening frame 12.2 trained clip attachment, which by a top side of the stiffening frame 12.2 trained angular shoulder or locking edge with which a joining partner is latching connectable, preferably designed as a corresponding trained locking edge on the support rail, so that engage behind the complementary trained locking edges in the installed position latching and releasable.

Further is at 5 to recognize that on the underside of the device carrier side next to the module channel 12.1 to the optical center of the device carrier 12 inclined reflection surfaces 12.8 . 12.9 are formed, which to the outside of the device carrier 12 rise, so bundle the luminous flux to the optical center.

Finally, in 5 To begin with to recognize the structure of the optical system according to the invention, which closer in the 15 and 16 is explained. This coding system comprises on the inside of the optics 18 a plurality of spaced apart in the longitudinal direction of each other in pairs rod-shaped spacers 18.4 . 18.5 , which may have at its upper ends two different sized supports, in the form of a lower and wider Erstauflagers and compared to this lower Erstlauflager offset upwards and compared to the Erstauflager also smaller Zweitauflagers. The spacers with the supports formed on the upper side are in pairs on both sides of the middle collimator lens 18.2 and spaced apart longitudinally from each other on the inside of the optic 18 intended to support the LED modules 14 which have at the edge with the first or second supports corresponding recesses which are formed so corresponding to the supports, that these recesses rest either on the wider Erstauflagern, bringing the LED module 14 closer to the optics 18 is arranged, or rest on the smaller secondary supports, bringing the LED module 14 further from the optics 18 is spaced. For this purpose, the recesses are correspondingly positioned differently sized, so that in the installed position in a first orientation, the larger recesses rest on the Erstauflagern and in a second orientation, compared to the first orientation z. B. is rotated 180 degrees about a central axis of rotation, rest with the smaller recesses on the second supports. Thus, two different optical systems can be realized by simply rotating the LED modules about the central pivot point two with the same optics.

The 6 and 7 show basic versions of equipment carriers 20 . 22 comprising only a substantially planar and a mounting plane defining, closed frame member having a central, longitudinally extending module opening 20.1 . 22.1 for receiving the at least one LED module 14 having.

In the in the 6 illustrated equipment carrier 20 for an extension module is the centrally formed, elongated module opening 20.1 also by spaced in the lamp longitudinal direction each other spring bridges 20.2 bridged, which in the installed position on the top of the LED module, not shown 14 abut and thus fix this in the installation position or push down, ie in the module opening 22.1 fix in the optical target position.

7 however, shows a device carrier 22 designed as a base module with a central module opening 22.1 without spring bridges.

The front ends of the device carrier 20 . 22 can each have a connection bridge 28 be electrically connected to each other, the structure better in the enlarged end view according to 9 is apparent. Accordingly, in particular at the adjacent shorter front ends of the equipment carrier in pairs electrical contact pins 20.3 . 20.4 be formed, which from the main level of the device carrier 20 . 22 protrude upwards. In each case four such contact pins adjacent to the front ends adjacent in the installation position 20.3 . 20.4 are about one in the 9 and the 6 illustrated patch connection bridge 28 electrically connectable to each other, so that thus a wiring, in particular a through-wiring between the mounting position in the frontally adjacent device carrier modules is realized.

10 shows an alternative embodiment of an alternative modular continuous-line luminaire comprising two end modules arranged on the end side 30 . 32 and an interposed, much longer extension module 34 , The front end module in the figure 30 In turn, for receiving the electronic components comprises a centrally formed channel with a top side mounted thereon support plate with the electrical lighting components. Instead of a contact comb here is a cable 36 intended for the primary contacting. The central extension module 34 In contrast to those in the 6 to 9 Embodiments shown a closed top module channel or a bridge for fixing the LED modules. Also in the figure rear end module 32 is formed with such a closed, central module channel, so that the LED modules 14 also over the ends of the device carrier modules 30 . 32 . 34 can extend.

The 11 illustrates the manufacturing or assembly process according to the invention, according to which the assembly can be done only in a mounting direction, from bottom to top without rotation of the components or components. First, on a mounting plane, not shown, the optics 18 put on and then on top of this in the appropriate orientation one or more LED modules 14 , which therefore on the lower Erstlauflagern or rotated 180 degrees on the higher Zweitauflagern on the optics 18 molded spacers 18.4 . 18.5 sit in pairs opposite to the optical center and along the optical axis spaced from each other. Then the device carrier composed here of device carrier modules 12 on the optics 18 and the LED modules 14 put on top, making the LED modules 14 , the linear impact side adjacent to each other within the module channel 12.1 of the device carrier 12 are recorded are fixed in position in their optical target position. Then can already equipped with electrical lighting components carrier plate 16 in a top channel of the device carrier 12 be placed so that the contact pins 16.1 . 16.2 are included in the contact guides 12.6 . 12.7 and in installation position on the underside engaging in the contact terminals 14.1 . 14.2 of the LED module 14 , Finally, the individual lighting components / components of the completely made of plastic lamp by ultrasonic welding in this thus defined target position cohesively and thus inextricably linked together.

The 12-14 , which each represent isometric frontal cross sections through the continuous line luminaire, illustrate the possibilities, the LED modules 14 different at different heights within the module channel 12.1 to arrange.

In the embodiment according to 12 is the LED module 14 directly within the module channel 12.1 taken and lies on the upper side of the shoulders formed on both sides within the module channel 12.1 on.

In the 13 On the other hand, the illustrated embodiment comprises above the LED module 14 a performance-enhancing heat sink 15 whose size corresponds to that of the LED module. The LED module 14 but is about 1 mm compared to the embodiment according to 12 lowered down or arranged lower.

14 shows an embodiment in which the LED module 14 in a lowered position and without a heat sink 15 in the module channel 12.1 is recorded, which is done in this case by the fact that the device carrier 12 at least one, preferably a plurality of spring bridges as shown in FIG 6 are provided which the LED module 14 down to the optics 18 presses, with the at least one spring bridge 20.2 has such a large spring travel that the LED module 14 alone or with the cooling plate 15 between optics 18 and the spring bridge 20.2 can be used. Preferably, a plurality of spring bridges in the lamp longitudinal direction of the equipment carrier 12 formed, which may be formed either on the device carrier or formed as connectable to the device carrier components.
