Abstract

A light bulb is disclosed herein, which in general, includes a light transmitting bulb portion and a base portion. The light transmitting bulb portion includes a first gear and an aperture. The base portion includes a second gear. The first gear is rotated independently of the second gear to direct light produced by the light bulb in a direction defined by a rotational position of the light transmitting bulb portion.

First claim

1 . A light bulb comprising:
a light transmitting bulb portion comprising a first gear and an aperture; a base portion comprising a second gear; and wherein the first gear is rotated independently of the second gear to direct light produced by the light bulb in a direction defined by a rotational position of the aperture of the light transmitting bulb portion.

2 . The light bulb of claim 1 , wherein the base portion comprises an Edison screw.

3 . The light bulb of claim 1 , wherein the light transmitting bulb portion rotates synchronously with the base portion in a clockwise direction until a predetermined torque is reached.

4 . The light bulb of claim 3 , wherein the light transmitting bulb portion rotates synchronously with the base portion in a counter-clockwise direction before and after the predetermined torque is reached.

5 . The light bulb of claim 1 , wherein the light transmitting bulb portion further comprises a light reflecting portion on an inner surface of the light transmitting bulb portion.

6 . The light bulb of claim 5 , wherein the light reflecting portion is substantially parabolic in shape.

7 . The light bulb of claim 6 , wherein the substantially parabolic shape forms a parabolic reflector which comprises more than 40% of an inner surface of the light transmitting bulb portion.

8 . The light bulb of claim 1 , further comprising one or more light sources.

9 . The light bulb of claim 8 , wherein one or more light sources are LED (light emitting diode) light sources.

10 . The light bulb of claim 8 , wherein light transmitted from the one or more LED light sources is transmitted through the light transmitting bulb portion of the light bulb when the light bulb is “on”.

11 . The light bulb of claim 8 , wherein the light transmitting bulb portion is pulled away from the base portion to disengage the first gear from the second gear.

12 . The light bulb of claim 11 , wherein the light transmitting bulb portion is rotatable while the light bulb is turned “on” without rotating the one or more LED light sources.

13 . The light bulb of claim 9 , wherein the LED light sources transmit light through the aperture in the light transmitting bulb portion.

14 . The light bulb of claim 8 , wherein the one or more light sources are induction light sources.

15 . The light bulb of claim 8 , further comprising a controller and a power supply operably connected to the one or more light sources.

16 . The light bulb of claim 15 , wherein the controller comprises a processor, memory, and one or more transceivers.

17 . The light bulb of claim 11 , further comprising a spring.

18 . The light bulb of claim 17 , wherein the spring pushes the light transmitting bulb portion toward the base portion.

19 . The light bulb of claim 1 , wherein the first gear and the second gear interlock to screw the base portion into a light socket.

20 . The light bulb of claim 1 , wherein the first gear and the second gear interlock to unscrew the base portion out of a light socket.
