Abstract

A combination light and sound producing fixture and combination screw-in light with speakers element is disclosed where the fixture is installed in a wall or ceiling or on a wall or ceiling. The light bulb/speaker can be screwed or secured into a standard light bulb socket. The sound producing elements is a coaxial arrangement of speakers having a low frequency transducer and one or more high frequency transducers that can be directed to emit sound in a particular direction. The fixture or bulb may further include digital signal processing to modify the sound to account for obstructions in or near the fixture. The surface of the sound transducer can be reflective in nature to provide focusing or diffusion of the light from the lighting elements. The lighting elements are incandescent, fluorescent or low voltage LED type that may include adjustment for lighting intensity and color.

Claims

1. A combination speaker lighting bulb comprising:

at least one light emitting illumination element, in combination with

at least one sound emitting element;

a light reflecting element that reflects light from said at least one light emitting illumination element into a plurality of directions;

an electrical connector configured for engage into a lighting socket, wherein

said electrical connector provides power to said at least one low voltage illumination element and said at least one sound emitting element.

2. The combination speaker lighting bulb according to claim 1 in which said light reflecting element is a bugle-head reflector.

3. The combination speaker lighting bulb according to claim 2 wherein said bugle-head reflector has an opening at the apex of said bugle-head reflector.

4. The combination speaker lighting bulb according to claim 3 that further includes a horn that reflects illumination emitted through said opening.

5. The combination speaker lighting bulb according to claim 1 that further includes at least one light emitting illumination element configured to shines light from the bottom of said bulb.

6. The combination speaker lighting bulb according to claim 1 in which said bulb further includes a digital signal processor to at least partially modulate a signal to the sound emitting element.

7. The combination speaker lighting bulb according to claim 1 that further includes a wireless receiver to receive a wireless signal that is transmitted through said at least one sound emitting element.

8. A combination speaker lighting bulb comprising:

an electrical base configured for insertion into a standard illumination base;

a housing secured to said electrical base providing a structural to support a lamp shade;

a power conversion circuit for converting electrical power from said electrical base into voltage to power at least one illumination element, a signal processor, an amplifier and a sound emitting element, wherein

said digital signal processor at least partially modulates a signal to said sound emitting element.

9. The combination speaker lighting bulb according to claim 8 in which a plurality of sound emitting elements are utilized.

10. The combination speaker lighting bulb according to claim 8 in which the fixture further includes a wireless receiver to receive a signal that is transmitted out of said at least one sound emitting element.

11. The combination speaker lighting bulb according to claim 8 that further includes a wireless receiver to receive a wireless signal that is transmitted through said at least one sound emitting element.

12. A combination speaker lighting bulb comprising:

an electrical base configured for insertion into a standard illumination base;

a housing having a back end secured to said electrical base providing a structural to support at least one illumination element and at least one sound producing element;

said housing having a front end with at least one sound producing element, and

said front end further having at least one light producing element located in front of said at least one sound producing element.

13. The combination speaker lighting bulb from claim 12 wherein said at least one illumination element is secured to said housing with a connection mechanism that spans above said at least one sound producing element.

14. The combination speaker lighting bulb from claim 13 wherein said securing to said housing spans across the sides of said housing and over said at least one sound producing element.

15. The combination speaker lighting bulb from claim 14 wherein said securing mechanism further includes a heat sink.

16. The combination speaker lighting bulb from claim 12 wherein said at least one light producing element is a cluster LED.

17. The combination speaker lighting bulb according to claim 12 in which said electrical base is an intermittent, medium, candelabra, bayonet or a pin type base.

18. The combination speaker lighting bulb according to claim 12 that further includes a wireless receiver to receive a signal that is transmitted out of said at least one sound emitting element.

19. The combination speaker lighting bulb according to claim 12 that further includes digital signal processor at least partially modulates a signal to said at least one sound emitting element.

20. The combination speaker lighting bulb according to claim 12 wherein said at least one sound producing elements is mechanically adjustable to change the direction of sound transmission.
