Abstract

A laser light configured to be socket compatible with an incandescent bulb. The laser light bulb fits into a standard base for a number of standard incandescent bulbs. The laser light bulb receives AC power from the light socket, and has an overall shape or envelope similar to the incandescent bulb being replaced. Internal to the envelope are electronics needed to power the laser, and the laser itself.

Claims

1. An illumination system comprising:

a conventional incandescent lighting system having an incandescent light fixture; and

a laser light socket bulb disposed in the incandescent light fixture, the laser light socket bulb including;

a housing having an envelope size compatible with an incandescent bulb of the incandescent light fixture;

a standard AC socket base to fit the incandescent light fixture;

a power supply inverter assembly internal to the housing;

a laser driver assembly coupled to the power supply inverter, and internal to the housing providing electronics for controlling a laser diode, that producing decorative lighting effects; and

a heat sink laser diode assembly internal to the housing and coupled to the laser driver assembly.

2. The illumination system of claim 1 in which the standard AC socket is an Edison type base.

3. The illumination system of claim 1 further comprising a removable cap including a device disposed in the path of a laser beam emitting from the housing.

4. The illumination system of claim 2 in which the device is a lens.

5. The illumination system of claim 2 in which the device is a diffraction grating.

6. The illumination system of claim 2 in which the device is a filter.

7. A laser light socket bulb, comprising;

a housing having an envelope size compatible with an incandescent bulb of the incandescent light fixture;

a standard AC socket base to fit the incandescent light fixture;

a power supply and laser driver electronics internal to the housing; and

a laser internal to the housing and coupled to the power supply and laser driver electronics, and where the driver electronics control the laser producing decorative lighting effects.

8. The laser light socket bulb of claim 7 further comprising a heat sink disposed in the housing and thermally coupled to the laser diode.

9. The laser light socket bulb of claim 7 further comprising a diffraction grating disposed the path of light emitting from the laser.

10. The laser light socket bulb of claim 7 in which the laser is a laser diode.

11. The laser light socket bulb of claim 7 in which the laser light socket bulb has a form factor of a standard incandescent bulb allowing the laser light socket bulb to replace the standard incandescent bulb in a fixture designed to accept the standard incandescent bulb.

12. The laser light socket bulb of claim 7 further comprising an end cap for inserting a device for creating visual effects in a path a laser beam emitting from the laser light socket bulb.

13. The laser light socket bulb of claim 12 in which the device is a filter.

14. The laser light socket bulb of claim 12 in which the device is a lens.

15. The laser light socket bulb of claim 12 in which the end cap is removable.

16. The laser light socket bulb of claim 15 in which the device is a manually adjustable diffraction lens.

17. The laser light socket bulb of claim 15 in which the device is a transparent lens.

18. A method of making a laser light socket bulb comprising:
