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 low voltage illumination element, in combination with at least one sound emitting element;

an electrical connector configured for engagement into a threaded base lighting bulb socket, wherein

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

said bulb further includes a digital signal processor configured at least partially to modulate a signal to the sound emitting element to at least partially compensate for placement and or obstructions within or near the bulb.

2. The combination speaker lighting bulb according to claim 1 in which said at least one low voltage illumination element is an LED.

3. The combination speaker lighting bulb according to claim 1 in which said at least one low voltage illumination elements consist of an array of low voltage lighting element.

4. The combination speaker lighting bulb according to claim 1 in which said electrical connector is at least one of the following:

an intermittent, medium, candelabra and a bayonet type base.

5. The combination speaker lighting bulb according to claim 1 in which the direction of illumination of said at least one low voltage illumination element is manually adjustable to focus and or disperse said illumination.

6. The combination speaker lighting bulb according to claim 1 in which the orientation of said at least one sound emitting is adjustable.

7. The combination speaker lighting bulb according to claim 1 wherein light from said at least one low voltage illumination elements is configured to focus or diffuse light from said at least one low voltage illumination elements.

8. The combination speaker lighting bulb according to claim 1 wherein said at least one low voltage illumination elements are placed around said light bulb to simulates the illumination of an incandescent light bulb.

9. 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.

10. A combination speaker lighting bulb comprising:

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

a power conversion circuit for converting the 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 to at least partially compensate for placement and or obstructions within or near the bulb.

11. The combination speaker lighting bulb according to claim 10 in which the at least one illumination element is a low voltage lighting element.

12. The combination speaker lighting bulb according to claim 10 in which the digital signal processor include filtering of 58 to 62 Hz noise.

13. The combination speaker lighting bulb according to claim 10 wherein said bulb further comprises a plurality of sound emitting elements.

14. The combination speaker lighting bulb according to claim 13 in which at least one of said sound emitting elements can be repositioned on said bulb.

15. The combination speaker lighting bulb according to claim 10 in which said electrical base is at least one of the following:

an intermittent, medium, candelabra and a bayonet type base.

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

17. The combination speaker lighting bulb according to claim 10 wherein said at least one illumination element is a plurality of low voltage illumination elements configured to provide focused or flood lighting.

18. The combination speaker lighting bulb according to claim 10 wherein said at least one illumination element is a plurality of low voltage illumination elements that are placed around said light bulb to simulates the illumination of an incandescent light bulb.

19. The combination speaker lighting bulb according to claim 10 that further includes a wireless receiver to receive a wireless signal that is utilized to emit an audio signal through said at least one sound emitting element.
