Abstract

A lighting apparatus having a light source and a leveling mechanism capable of maintaining the light source in a desired orientation is described. The lighting apparatus may have a pivot mechanism about which the light source is capable of rotating such that the lighting apparatus maintains the desired orientation. In specific embodiments, the lighting apparatus comprises a directional light source, a pivot mechanism, a connector capable of connecting the pivot to another object, and a mechanism that allows the light source to rotate about the pivot to maintain a desired orientation. The lighting apparatus may be connected to an object, such as a piece of wheeled luggage, such that when the luggage is tilted the light source maintains an desired orientation such as a horizontal orientation.

Claims (51)

1. The lighting apparatus, comprising:

a first light source,

a pivot connected to the light source; and

a leveling mechanism capable of urging the light source to rotate about the pivot to maintain a desired orientation, wherein the leveling mechanism comprises a sealed cylindrical body and a liquid within the sealed cylindrical body.

2. The lighting apparatus of claim 1 , wherein the first light source is within the sealed cylindrical body, is connected to the sealed cylindrical body by the pivot and is capable of rotating about the pivot within the sealed cylindrical body.

3. The lighting apparatus of claim 2 , wherein the sealed cylindrical body is about half filled with the liquid or less.

4. The lighting apparatus of claim 3 , wherein the pivot is connected substantially to the center of the sealed cylindrical body.

5. The lighting apparatus, comprising:

a first light source,

a pivot connected to the light source; and

a leveling mechanism capable of urging the light source to rotate about the pivot to maintain a desired orientation, wherein the leveling mechanism comprises a cylindrical body, wherein the first light source is within the cylindrical body, is connected to the cylindrical body by the pivot and comprises a counter weight connected to a bottom portion of the light source that is capable of rotating the first light source about the pivot when the cylindrical body is rotated about the pivot.

6. The lighting apparatus, comprising:

a first light source,

a pivot connected to the light source;

a leveling mechanism capable of urging the light source to rotate about the pivot to maintain a desired orientation; and

at least one counterweight connected to a bottom portion of the first light source, wherein the first light source comprises a power source, a light, and light source housing.

7. The lighting apparatus of claim 6 , wherein the first light source comprises a power source, a light, and light source housing.

8. The lighting apparatus of claim 6 , comprising a connector capable of attaching the lighting apparatus to an object.

9. The lighting apparatus of claim 8 , wherein the connector comprises at least one of a hook and loop connector, adhesives, double sided tape, a bracket for a square tube, a bracket for a round tube, a U-type bracket, a lab frame type connector with a thumb screw, a screw, a bolt, a bracket, a magnet, and a suction cup.

10. The lighting apparatus of claim 6 , wherein the counterweight is connected to the light source housing.

11. The lighting apparatus of claim 10 , wherein the counterweight comprises the power source.

12. The lighting apparatus of claim 11 , wherein the power source is a battery.

13. The lighting apparatus of claim 6 , wherein the first light source is a directional light source.

14. The lighting apparatus of claim 6 , the pivot comprises a horizontal axle.

15. The lighting apparatus of claim 6 , wherein the pivot comprises a releasable connector.

16. The lighting apparatus, comprising:

a first light source,

a pivot connected to the light source; and

a leveling mechanism capable of urging the light source to rotate about the pivot to maintain a desired orientation, wherein the pivot is attached to a top portion of the light source and the leveling mechanism comprises a counterweight comprising at least one battery.

17. The lighting apparatus of claim 16 , comprising a second light source.

18. The lighting apparatus, comprising:

a first light source and a second light source,

a pivot connected to the light source; and

a leveling mechanism capable of urging the light source to rotate about the pivot to maintain a desired orientation, wherein the second light source is a directional light source and is directed in a different direction than the first light source.

19. The lighting apparatus of claim 18 , a connector for removably attaching the lighting apparatus to a tubular frame for hands free use.

20. A lighting apparatus, comprising:

a plurality of light sources directed in different directions and mounted in an array around the peripheral surface of a housing,

a power source, and

an integrated circuit, wherein the integrated circuit comprises:

a gyroscope circuit that generates a orientation parameter based on orientation of the lighting apparatus compared to a horizontal position; and

a processing module in electrical communication with the gyroscope circuit to receive the orientation parameter and to activate a light source or set of light sources of the plurality of light sources to direct light in the desired direction and to deactivate the light sources not directed in the desired direction based upon the orientation parameter.

21. The lighting apparatus of claim 20 , wherein the plurality of light sources are arranged around the peripheral surface of a cylindrical housing and project radially.

22. The lighting apparatus of claim 20 , wherein the plurality of light sources are arranged around the circumference of a spherical housing.

23. The lighting apparatus of claim 20 , wherein the gyroscope circuit comprises at least one of a piezoelectric gyroscope, a vibrating wheel gyroscope, a tuning fork gyroscope, a hemispherical resonator gyroscope, or a rotating wheel gyroscope.

24. The lighting apparatus of claim 20 , wherein the desired direction is a horizontal direction.

25. A lighting apparatus, comprising:

a plurality of light sources,

a power source, and

an integrated circuit, wherein the integrated circuit comprises:

a gyroscope circuit that generates a orientation parameter based on orientation of the lighting apparatus compared to a horizontal position; and

a processing module in electrical communication with the gyroscope circuit to receive the orientation parameter and to activate the plurality of light sources, wherein the processing unit activates at least a portion of the light sources based upon the orientation parameter, wherein the processing unit activates a portion of the light sources based upon difference between a previous value of the orientation parameter and a current value of the orientation parameter.
