Description

The invention relates to a rectilinear and extending in the longitudinal direction light for a light strip according to the preamble of claim 1.

Lights for a light band are already known from the prior art. The light band usually comprises a plurality of linear lights, which are mounted in a row on a wall or on a ceiling. The respective lamp usually comprises a support profile with a current-carrying rail on which a device carrier is fixed with a light source plate. The light source plate with multiple light sources is powered by the power guide rail and controlled by a controller in the support profile. The equipment carrier is usually closed with an optical cover over which the light generated by the light sources is scattered. In the lamp many components must be assembled, whereby the assembly is difficult and the production costs are increased.

The object of the invention is to provide for the lamp of the generic type an improved or at least alternative embodiment, in which the disadvantages described are overcome.

This object is achieved by the subject of independent claim 1. Advantageous embodiments are the subject of the dependent claims.

The present invention is based on the general idea of assembling individual components in a luminaire together and thereby simplifying the assembly of the luminaire. The rectilinear and longitudinally extending light is provided for a light band and has an elongated U-shaped support profile and an elongated U-shaped device carrier, which is fixed in a form-fitting manner to the support profile. The device carrier encloses the support profile transversely to the longitudinal direction at least partially with a profile closure base and thereby a profile interior is formed in the support profile. The lamp also has at least one elongate optical cover which is fixed to the device carrier. The at least one optical cover closes the device carrier transversely to the longitudinal direction and thereby a carrier interior is formed in the device carrier. The luminaire also has at least one elongate luminous support plate with a plurality of light sources, which is fixed in the carrier interior of the device carrier. According to the invention, the luminaire has at least two elongated V-shaped retaining clips, each with a first support wing and with a second support wing, which are each connected to one another by a supporting edge. The respective retaining clip is supported in the carrier interior space with the first support wing on the luminous support plate, with the second support wing on the at least one optical cover and with the support edge on an elongated support contour of the device support.

Suitably, the support profile may comprise a current-carrying rail with a plurality of electrical conductors, which can supply the plurality of light sources on the Leuchttragplatte with power. For this purpose, an electrical connection element can be provided on the luminescent support plate, by means of which the plurality of light sources on the luminescent support plate can be connected to the current-carrying rail. For this purpose, the electrical connection element can engage in the current-carrying rail and in this way electrically connect the plurality of light sources to at least one of the conductors of the current-carrying rail. The connection element can furthermore be electrically connected to a control device which can control the plurality of light sources individually or in groups. Suitably, the plurality of light sources are arranged on a front side of the luminous support plate, which is arranged facing the optical cover in the carrier interior. The electrical connection element can then be determined appropriately facing away from the front side of the rear side of the luminous support plate and thereby facing the profile interior.

In the luminaire according to the invention, the equipment carrier is closed with at least one optical cover. The at least one optical cover is suitably designed at least partially and at least partially light-transparent. The luminaire may, for example, have a single optical cover which closes the device carrier transversely to the longitudinal direction. Alternatively, several - and preferably two - optical covers may be provided which are arranged side by side transversely to the longitudinal direction and close the device carrier transversely to the longitudinal direction. In this case, the carrier interior can be divided in the longitudinal direction by at least one intermediate flange of the device carrier and the respective optical cover can then be fixed on one side between a flange of the device carrier and the respective intermediate flange adjacent to the flange or alternatively between two adjacent intermediate flanges. The respective intermediate flange may suitably have on both sides in each case the inner contour of the facing flange, so that the optical cover can be fixed to it. Accordingly, the distance between the flanges in a device carrier without an intermediate flange and the distance between the flanges to the respective intermediate flange and the intermediate flanges to each other in a device carrier with the respective intermediate flange can be the same. Advantageously, then the optical cover, the Leuchttragplatte and more in the equipment carrier arranged components in a device carrier with and without the at least one intermediate flange remain the same design.

By the respective retaining clip advantageously the luminescent support plate and the optical cover are fixed together in the carrier interior and additional fastening means omitted. As a result, both the manufacturing costs can be reduced and the installation of the luminaire can be simplified. In addition, disassembly of the optical cover is made difficult by the retaining clip according to the invention, so that the risk of injury to a non-responsible person is reduced.

Advantageously, it can be provided that the respective retaining clip by the first support wing presses the luminescent support plate in the carrier interior to the device carrier to the support profile. As a result, the luminescent support plate rests on the device carrier and the heat generated in the luminescent support plate can be dissipated to the device carrier. In addition, the respective retaining clip by the second support wing presses the at least one optical cover in the carrier interior to the light-supporting plate to the support profile out. In this way the luminescent support plate on the device carrier and the optical cover are pressed against the luminescent support plate to the support profile. As a result, the optical cover encloses the light sources fixed to the luminous support plate transversely to the longitudinal direction, and the light sources on the luminous support plate can thereby be better protected from contamination.

Furthermore, it can advantageously be provided that the first support wing of the respective retaining clip has at least one first bent-off bending area and at least one second bent-off bending area. The respective Abkantbereiche are bent transversely to the longitudinal direction and extend in the longitudinal direction. In this case, the at least one first Abkantbereich the luminescent support plate to the support profile towards the device carrier and the at least one second Abkantbereich the luminescent support plate parallel to the support profile and transverse to the longitudinal direction set laterally. The at least one first Abkantbereich and the at least one second Abkantbereich act both transverse to the longitudinal direction, so that the Leuchttragplatte is fixed in the longitudinal direction displaceably on the equipment carrier. In particular, thermal expansion of the luminescent support plate in and across the longitudinal direction can thereby be compensated for and distortion of the luminescent support plate during operation of the luminaire can be advantageously prevented.

In the carrier interior, a retaining clip can be arranged on both sides on the light-supporting plate, so that the light-supporting plate is fastened to the device carrier fittingly and transversely to the longitudinal direction so as to be fixed by the bending areas of the first supporting wing of the respective retaining clips. The respective second bending regions of the first support wing of the respective retaining clips do not prevent thermal expansion of the luminous support plate transversely to the longitudinal direction, so that distortion of the lighting support plate during operation of the luminaire can be advantageously prevented.

Advantageously, it can also be provided that the second support wing of the respective retaining clip has at least one third bent Abkantbereich which is bent transversely to the longitudinal direction and extending in the longitudinal direction. The third Abkantbereich sets while the at least one optical cover to the luminescent support plate down. The third Abkantbereich the second support wing of the respective retaining clip can rest against a longitudinally extending support surface of the optical cover to allow large-area contact of the second Abstützflügels with the optical cover.

In order to fix the respective retaining clip in the device carrier in a longitudinally displaceable manner, a plurality of grounding tips can be integrally formed on the supporting edge of the respective retaining clip. The grounding tips attach the retaining clip in the longitudinal direction to the respective support contour of the device carrier.

In an advantageous development of the luminaire according to the invention, provision is made for a seal extending in the longitudinal direction to be arranged between the at least one optical cover and the device carrier. The seal is supported on one side on the equipment carrier and on the other side on the at least one optical cover and sets the at least one optical cover to the support profile out in the carrier interior.

Advantageously, the seal can press the luminescent support plate to the device carrier to the support profile. In particular, the optical cover can be securely fixed to the device carrier and undesired loosening of the optical cover by the device carrier can thereby be prevented. For example, the gasket may be resilient to compensate for deformation of the optical cover or the device carrier due to thermal expansion during operation of the light. Advantageously, the seal may be molded onto the at least one optical cover to reduce manufacturing costs.

In an advantageous development of the luminaire according to the invention it is provided that the device carrier has a luminous support floor, which is arranged parallel to and spaced from the profile closing bottom and in the longitudinal direction extends. The luminous support floor divides the carrier interior into a luminous interior with the at least one luminous support plate and a heat insulating space, which is arranged in the longitudinal direction between the profile interior and the luminous interior. The luminescent support plate with the plurality of light sources is then arranged in the luminescent interior on the lighthousing floor fitting and can be determined by the respective retaining clips to this - for example, be pressed.

The Wärmeisolierraum is disposed between the luminous interior and the profile interior and isolated the profile interior and the luminous interior from each other. As a result, in particular the direct heat transfer between the luminescent support plate with the multiple light sources and electrical or electronic components in the profile interior - such as a control unit - can be minimized. In this way, the heat generated in the lamp can be preferably derived to the outside and the functionality of the lamp can be obtained advantageously.

Advantageously, it may be provided that the profile closure bottom is formed integrally by at least one projection facing the support profile on the light support floor of the equipment carrier, wherein the projection has a T-shaped cross-section transverse to the longitudinal direction and extending in the longitudinal direction. Alternatively, the profile closure bottom can be integrally formed by two lateral projections on the light-carrying floor of the equipment carrier, the projections facing each other and extending in the longitudinal direction. At the respective projections, both the support profile and electrical or electronic components in the profile interior - such as a control unit - be supported. The respective projection extends in the longitudinal direction purposefully over an entire length of the device carrier, so that the profile interior and the luminous interior are separated from each other over a whole length of the lamp heat-insulating.

In a further development of the device carrier is advantageously provided that the lighthouse support floor has at least one Führungsausformung for centering the luminescent support plate. The Führungsausformung is directed into the lighting interior and extends in the longitudinal direction. The Führungsausformung facilitates centered fixing of the light-supporting plate with the plurality of light sources in the luminous interior, whereby the mounting of the lamp is simplified.

Advantageously, the device carrier can be clamped in the support profile in the longitudinal direction on both sides. In particular, thereby the assembly and disassembly of the equipment carrier can be simplified to the support profile. For example, flanges of the device carrier can be arranged in the profile interior and clamped between flanges of the support profile in the longitudinal direction over an entire length of the support profile or the device carrier. In addition, on both sides in each case a clamping arrangement can be provided with a clamping groove and a clamping spring, which extend in the longitudinal direction and can be brought into engagement with one another transversely to the longitudinal direction. The respective clamping spring or clamping groove are then on the outside on the flanges of the device carrier and the respective clamping groove or clamping spring on the inside integrally formed on the flanges of the support profile. In order to simplify the mounting of the equipment carrier on the support profile, the equipment carrier on both sides each having a Griffrillenanordnung with a plurality of preferably parallel gripping grooves. The respective grip groove arrangement extends on the outside on a flange of the device carrier in the longitudinal direction.

In an advantageous embodiment of the device carrier is provided that the device carrier is an extruded in an extrusion of aluminum extruded part. Alternatively, the device carrier may be a formed sheet steel sheet metal part.

In an advantageous development of the luminaire according to the invention, it is provided that the at least one optical cover is centered on the device carrier by a centering arrangement in and transverse to the longitudinal direction and is designed to be expandable in the longitudinal direction. Centering arrangement may include, for example, a centering and a centering, which are engageable with each other transversely to the longitudinal direction. The respective Zentrierausnehmung or Zentrierausformung can then be formed on the optical cover and the respective Zentrierausformung or Zentrierausnehmung, for example, on the Leuchttragplatte. By means of the centering arrangement, optics arranged in the optical cover can be aligned relative to the multiple light sources of the luminous support plate, thereby reducing optical losses in the luminaire. The centering also does not prevent thermal expansion of the optical cover in the longitudinal direction and distortion of the optical cover during operation of the lamp can be advantageously prevented.

In an advantageous development of the optical cover, it is provided that the at least one optical cover has a plurality of integrally formed prisms. Preferably, the optical cover is then manufactured in an extrusion process. Alternatively, the at least one optical cover may include a plurality of integrally molded lenses. Preferably, the optical cover is then in produced by injection molding. Advantageously, the at least one optical cover may consist of a plurality of optical cover parts, which are arranged on the device carrier in the longitudinal direction one behind the other. In particular, this can simplify the production of an elongated optical cover in an injection molding process.

Advantageously, the optical cover can then have a centering arrangement which is integrated in the lenses. Thus, one of the lenses may have a centering recess and the illuminated support plate may have a centering formation which engage in one another and fix the lens in and across the longitudinal direction on the illuminated support plate. In particular, the lenses and the light sources can then remain centered relative to each other with thermal expansion of the luminescent support plate and the optical cover, and optical losses in the luminaire are advantageously reduced. Alternatively or additionally, the optical cover or the Optikabdeckteile identify at least one identification arrangement, which is integrally formed on both sides of the optical cover to the longitudinal direction. The identification arrangement may, for example, have a characteristic projection and a characteristic recess which can be brought into engagement with the identification projection, which prevents incorrect mounting of the optical covers or the optical cover parts in the longitudinal direction and also simplifies the assembly of the luminaire.

In summary, additional fastening means can be avoided in the luminaire according to the invention by the retaining clip and thus the assembly can be simplified; the heat generated in the luminaire is preferably dissipated to the outside through the heat insulation space and the functionality of the luminaire is advantageously preserved; protected by the seal of the illuminated interior from dirt particles and the optical cover are securely fixed to the equipment carrier; and the centering arrangement on the optical cover compensates for the thermal expansion of the optical cover and advantageously reduces optical losses.
