Abstract

A lighting fixture comprising: an elongate housing having an outer surface and an inner surface and having an elongate opening extending in a longitudinal direction of the housing; wherein the elongate housing comprises a first wall and a second wall extending towards the elongate opening; a light module for emitting light having a first face through which light is emitted and an opposite second face; a plurality of retainer means provided at the second face and configured for engaging the first and second walls such that the light module is retained within the elongate housing; a stopper means for preventing inward displacements of the light module past a predetermined boundary.

First claim

The invention claimed is:

1. A lighting fixture comprising:
an elongate housing having an outer surface and an inner surface and having an elongate opening extending in a longitudinal direction of the housing;
wherein the elongate housing comprises a first wall and a second wall extending towards the elongate opening;
a light module for emitting light having a first face through which light is emitted and an opposite second face;
a plurality of retainer means provided at the second face and configured for engaging the first and second walls such that the light module is retained within the elongate housing;
a stopper means for preventing inward displacements of the light module past a predetermined boundary.

2. The fixture of claim 1 , wherein the plurality of retainer means comprises at least a first spring element and a second spring element having a protruding portion snap-fitted behind a first ridge and a second ridge at the first wall and the second wall, respectively, when looking from the elongate opening in the direction of the inner surface.

3. The fixture of claim 2 , wherein the spring element comprises a first portion extending upwardly from the second face of the light module;
and wherein the protruding portion is a curved portion formed at an upper edge of the first portion.

4. The fixture of claim 1 , wherein the stopper means comprises at least one element configured for engaging an edge of the first and the second wall.

5. The fixture of claim 3 , wherein the stopper means is configured to prevent further inward displacements of the light module when the protruding curved portion of each of the plurality of retainer means is behind the first and second ridge.

6. The fixture of claim 1 , wherein the light module has a first and a second longitudinal side extending in the longitudinal direction, and a first and a second lateral side extending between the first longitudinal side and the second longitudinal side;
and wherein the at least one element of the stopper means comprises a first lateral edge at the first lateral side of the light module extending from the second face of the light module in direction of the first and second wall, and a second lateral edge at the second lateral side of the light module extending from the second face of the light module in direction of the first and second wall.

7. The fixture of claim 1 , wherein the light module comprises:
a support substrate with at least one LED disposed thereon;
a lighting housing comprising a base portion and a cover;
said cover extending over the at least one LED and being fixed to said base portion.

8. The fixture of claim 7 , wherein the light module further comprises:
a lighting plate containing a thermally conductive material and having a first surface and a second surface, wherein the support substrate is provided on the second surface of the lighting plate, wherein the first surface of the lighting plate faces the base portion of the lighting housing.

9. The fixture of claim 7 , wherein the cover extends between outer edges of the elongate opening.

10. The fixture of claim 7 , wherein the cover is located at least partially within the elongate housing.

11. The fixture of claim 7 , wherein the base portion and the support substrate are located entirely within the elongate housing.

12. The fixture of claim 7 , wherein the cover is located at least partially out of the elongate housing.

13. The fixture of claim 1 , wherein at least one electric component is mounted on the second face of the light module such that the at least one electric component is located in a space within the bounds of the inner surface of the elongate housing, the first and second walls, and the second face of the light module.

14. The fixture of claim 1 , wherein a second light module is retained longitudinally adjacent to a first light module by another plurality of retainer means within the elongate housing.

15. The fixture of claim 14 , wherein a lighting driver is mounted on the second face of the first light module, wherein the lighting driver is configured to control the provision of power to the at least one LED of the first light module and the second light module.

16. The fixture of claim 1 , wherein at least the first or second wall is composed of a first portion of the elongate housing extending towards the elongate opening and joining to another second portion of the elongate housing extending at an angle of the first portion, such that an external compartment for receiving cables and wires is created.

17. The fixture of claim 1 , wherein the first face of the light module is designed to align with the outer edges of the elongate opening when mounted within the elongate housing.

18. The fixture of claim 1 , wherein the elongate housing is an extruded profile, preferably in metal.

19. The fixture of claim 1 , wherein the elongate housing comprises an outer casing in which the elongate opening is arranged; wherein at least the first wall is arranged in the outer casing, such that a compartment delimited by the outer casing and the first wall is created.

20. A lighting fixture comprising:
an elongate housing having an outer surface and an inner surface and having an elongate opening extending in a longitudinal direction of the housing;
wherein the elongate housing comprises a first wall and a second wall extending towards the elongate opening;
a light module for emitting light having a first face through which light is emitted and an opposite second face;
a plurality of retainer means provided at the second face and configured for engaging the first and second walls such that the light module is retained within the elongate housing;
a stopper means for preventing inward displacements of the light module past a predetermined boundary;

wherein the light module comprises:
a support substrate with at least one LED disposed thereon;
a lighting housing comprising a base portion and a cover;
said cover extending over the at least one LED and being fixed to said base portion, wherein the cover is located at least partially within the elongate housing, and wherein the base portion is located entirely within the elongate housing;

wherein at least one electric component is mounted on the second face of the light module such that the at least one electric component is located in a space within the bounds of the inner surface of the elongate housing, the first and second walls, and the second face of the light module.

21. The lighting fixture of claim 20 , wherein the support substrate is located entirely within the elongate housing.

22. The lighting fixture of claim 20 , wherein the elongate housing has a planar support surface to fix the housing to a wall, said first side wall extending from the support surface, said second side wall extending from the support surface opposite of the first side wall, wherein the at least one electric component is located in a space between the first side wall and the second side wall.
