Abstract

A lighting device is disclosed to include a light source formed of light emitting diodes and/or laser diodes and controlled to emit light and/or to flash by a programmable controller, a lens, which has raised portions for refracting the light of the light emitting diodes and/or laser diodes to produce a lighting effect, and a driving mechanism for rotating the lens relative to the light source.

Claims

1. A lighting device comprising:

a light source, said light source comprising a circuit board, a plurality of light emitting devices installed in said circuit board, and a programmable controller electrically connected to said circuit board and adapted to control on/off and flashing of said light emitting device subject to a predetermined program;

a lens set in the path of the light emitted from said light emitting devices, said lens comprising a plurality of raised portions adapted to refract the light emitted from said light emitting devices; and

a driving means adapted to rotate one of said light source and said lens relative to the other of said light source and said lens.

2. The lighting device as claimed in claim 1, wherein said light emitting devices are laser diodes.

3. The lighting device as claimed in claim 1, wherein said light emitting devices are light emitting diodes.

4. The lighting device as claimed in claim 1, wherein said light emitting devices include light emitting diodes and laser diodes.

5. The lighting device as claimed in claim 1, wherein said light emitting devices have the same color.

6. The lighting device as claimed in claim 1, wherein said light emitting devices have different colors.

7. The lighting device as claimed in claim 1, wherein said driving means drives said light source to rotate relative to said lens.

8. The lighting device as claimed in claim 1, wherein said driving means drives said lens to rotate relative to said light source.

9. The lighting device as claimed in claim 1, wherein said raised portions of said lens protrude from an outer surface of said lens.

10. The lighting device as claimed in claim 9, wherein said raised portions have different shapes and sizes.

11. The lighting device as claimed in claim 9, wherein said raised portions are arranged in an array.

12. The lighting device as claimed in claim 9, wherein said raised portions are not aligned in line.

13. The lighting device as claimed in claim 1, wherein said lens is a flat lens.

14. The lighting device as claimed in claim 1, wherein said lens has an arched shape.

15. The lighting device as claimed in claim 1, wherein said the programmable controller can also control the rotation of the driving means causing it to start and stop periodically.
