Abstract

A lighting device includes a primary lighting module with one or more light sources and one or more secondary lighting modules each with one or more light sources. Each secondary lighting module is mechanically and electrically connected to the primary lighting module. At least one of the secondary lighting modules is movable with respect to the primary lighting module. The shape of the lighting device can be varied between different configurations.

First claim

The invention claimed is:

1. A lighting device comprising:
a primary lighting module with one or more light sources; and
at least one secondary lighting module with one or more light sources, wherein the at least one secondary lighting module is mechanically and electrically connected to the primary lighting module via a connecting module such that the at least one secondary lighting module is slidably movable and rotatably movable with respect to the primary lighting module, wherein the connecting module comprises:
a slide track; and
a sliding element slidingly received by the slide track, the sliding element comprising:
a first portion; and
a second portion rotatable relative to the first portion.

2. The lighting device of claim 1 , wherein the sliding element and the slide track both comprise stoppers adapted to interact with each other in order to limit the range of relative movement between the primary lighting module and the at least one secondary lighting module.

3. The lighting device of claim 1 , wherein the connecting module comprises a locking element for locking the sliding element with respect to the slide track.

4. The lighting device of claim 1 , wherein the first portion of the sliding element and the second portion of the sliding element comprise corresponding latching elements for securing the relative rotational position between the first portion of the sliding element and the second portion of the sliding element.

5. The lighting device of claim 1 , wherein the connecting module further comprises an electrical connector for providing an electrical connection between both ends of the connecting module, thereby providing an electrical connection between the sliding element and the slide track.

6. The lighting device of claim 5 , wherein the electrical connector comprises a cable having at least one length varying section allowing longitudinal extension and retraction of the cable.

7. The lighting device of claim 6 , wherein the length varying section comprises at least one of a helical cable portion and a retractable cable unit.

8. The lighting device of claim 5 , wherein the electrical connector comprises one or more fasteners for fastening the electrical connector to at least one of the sliding element and the slide track.

9. The lighting device of claim 1 , wherein the at least one secondary lighting module is movable between a collapsed state of the lighting device and an expanded state of the lighting device, wherein the primary lighting module and the at least one secondary lighting module are shaped such that the primary lighting module and the at least one secondary lighting module abut each other in the collapsed state of the lighting device without any gaps therebetween.

10. The lighting device of claim 1 , wherein:
the second portion of the sliding element is attached to one of either the primary lighting module or the at least one secondary lighting module; and
the slide track is attached to the other of either the primary lighting module or the at least one secondary lighting module.

11. The lighting device of claim 1 , wherein the at least one secondary lighting module is slidably movable with respect to the primary lighting module such that:
in a first position of the first portion of the sliding element relative to the slide track, the second portion of the sliding element is prevented from rotating relative to the first portion of the sliding element; and
in a different second position of the first portion of the sliding element relative to the slide track, the second portion of the sliding element is permitted to rotate relative to the first portion of the sliding element.

12. The lighting device of claim 1 , wherein the first portion of the sliding element and the second portion of the sliding element are joined by a hinge portion which permits rotation of the second portion relative to the first portion.

13. The lighting device of claim 12 , wherein:
in a first state of the connecting module, the hinge portion is at least partially positioned within the slide track such that the second portion of the sliding element is prevented from rotating relative to the first portion of the sliding element; and
in a different second state of the connecting module, the hinge portion is at least partially positioned outside of the slide track such that the second portion of the sliding element is permitted to rotate relative to the first portion of the sliding element.

14. The lighting device of claim 1 , further comprising a first driver hosted by the primary lighting module and configured to drive at least the one or more light sources of the primary lighting module.

15. The lighting device of claim 14 , wherein:
the first driver is configured to drive the one or more light sources of the primary lighting module; and
the lighting device further comprises a second driver hosted by the at least one secondary lighting module and configured to drive the one or more light sources of the at least one secondary lighting module.

16. A lighting device comprising:
a first lighting module comprising a first light source;
a second lighting module comprising a second light source; and
a connecting module connecting the second lighting module to the first lighting module such that the second lighting module is slidably movable and rotatably movable with respect to the first lighting module, wherein the connecting module comprises:
a slide track; and
a sliding element slidingly received by the slide track;

wherein electrical connection between the first lighting module and the second lighting module is provided by a cable at least partially situated within the connecting module and adapted to compensate for translational movement and rotational movement of the second light module relative to the first lighting module.

17. The lighting device of claim 16 , wherein the connecting module permits rotation of the second lighting module in a manner which adjusts at least one of a convergence and a divergence of an output of the lighting device.

18. The lighting device of claim 16 , wherein the sliding element includes a hinge portion which permits rotation of the second lighting module relative to the first lighting module in a manner which adjusts at least one of a convergence and a divergence of an output of the lighting device.

19. The lighting device of claim 16 , wherein:
the slide track is fixedly provided at the first lighting module; and
the sliding element is fixedly provided at the second lighting module.

20. The lighting device of claim 16 , wherein:
the slide track is fixedly provided at the second lighting module; and
the sliding element is fixedly provided at the first lighting module.

21. The lighting device of claim 16 , wherein the lighting device comprises a plurality of second lighting modules, wherein the plurality of second lighting modules are at least one of slidably movable and rotatably movable with respect to the first lighting module in an individual or independent manner.

22. The lighting device of claim 16 , wherein the lighting device comprises a plurality of second lighting modules, wherein the plurality of second lighting modules are at least one of slidably movable and rotatably movable with respect to the first lighting module in a synchronized or simultaneous manner.

23. The lighting device of claim 16 , wherein the first lighting module hosts an electronic driver configured to drive b
