Abstract

An angle adjustment device comprises a support member, a plurality of holders for light emitting or receiving devices, each holder being supported by the support member for pivoting about at least one axis and an elongate spiral element which co-operates with the holders so that when the spiral element is displaced angularly about its axis relative to the support member, each holder pivots about its said at least one axis.

Claims

1. Automated lighting having a source of light formed by a plurality of light emitting diodes (LEDs) that are pivotably mounted on a support member with a universal joint so that said LEDs are adjustable to change at least one of an angle and a shape of a light beam produced by said LEDs.

2. The lighting of claim 1, wherein each of said LEDs comprises red, blue and green guns.

3. The lighting of claim 1, wherein said support member is planar.

4. The lighting of claim 1, wherein said support member is non-planar.

5. The lighting of claim 1, wherein each of said support member is movable between a planar and a non-planar configuration.

6. The lighting of claim 1, wherein each of said LEDs is pivotable in directions that are at right angles to each other.

7. The lighting of claim 1 wherein adjustment of said LEDs is performed by an electric motor.

8. The lighting of claim 1, wherein adjustment of said LEDs emit white light.

9. A lighting apparatus, comprising:

a support; and

plural light emitting diodes (LEDs) that are each pivotably mounted on said support with a universal joint and that together form a source of light.

10. The lighting apparatus of claim 9, wherein said support is movable between a planar and non-planar configuration.

11. The lighting apparatus of claim 9, wherein the source of light is a white light.

12. The lighting apparatus of claim 9, further comprising at least two elongated elements that are attached to said LEDs and that are movable and cause pivotal motion of said LEDs.

13. The lighting apparatus of claim 9, wherein each of said LEDs is pivotable in directions that are at right angles to each other.

14. A lighting apparatus, comprising:

a support;

plural light emitting diodes (LEDs) that are each pivotably mounted on said support and that together form a source of light; and

elongated elements attached to said LEDs that are movable and cause pivotal motion of said LEDs.

15. The lighting apparatus of claim 14, wherein said support is movable between a planar and non-planar configuration.

16. The lighting apparatus of claim 14, wherein each of said LEDs is attached to said support with a universal joint.

17. The lighting apparatus of claim 14, wherein the source of light is a white light.

18. The lighting apparatus of claim 14, wherein each of said LEDs is pivotable in directions that are at right angles to each other.

19. Automated lighting having a source of light formed by a plurality of light emitting diodes (LEDs) that are pivotably mounted on a support.

20. The lighting apparatus of claim 19, wherein said LEDs are attached to said support with a joint.

21. The lighting apparatus of claim 19, wherein the source of light is a white light.

22. The lighting apparatus of claim 19, further comprising at least two elongated elements that are attached to said LEDs and that are movable and cause pivotal motion of said LEDs.

23. The lighting apparatus of claim 19, wherein said LEDs are pivotable in directions that are at right angles to each other.

24. The lighting apparatus of claim 19, wherein the apparatus has a center axis and said LEDs are pivotable in directions that are at right angles to the center axis of the apparatus.

25. The lighting apparatus of claim 19, wherein the apparatus has a center axis and said LEDs is pivotable in directions in-line with the center axis of the apparatus.

26. The lighting apparatus of claim 19, wherein the pivoting of the LEDs results in modification of the width of the light beam formed by the LEDs.

27. The lighting apparatus of claim 19, wherein the pivoting of the LEDs results in modification of the direction of the light beam formed by the LEDs.

28. A lighting apparatus comprising a plurality of light emitting diodes (LEDs) that are pivotably mounted on support to form a light beam whose characteristics change as the LEDs are pivoted.

29. The lighting apparatus of claim 28 where a characteristic of the light beam that changes as the LEDs pivot is the height of the beam.

30. The lighting apparatus of claim 28 where a characteristic of the light beam that changes as the LEDs pivot is the direction of the light beam.

31. The lighting apparatus of claim 28 where the light beam width and/or direction change as the LEDs pivot.

32. The lighting apparatus of claim 28 where the light beam height and/or width and/or direction change as the LEDs pivot.
