Abstract

In one aspect, the present invention relates to an illumination system including a power source, a light source electrically coupled to the power source, and a light sensor electrically coupled to the power source and the light source. The light sensor activates the light source responsive to a pre-determined minimum-lumen threshold being reached. The illumination system is placed inside an interior of a dark area.

Claims

1. An illumination system comprising:

a power source;

a light source electrically coupled to the power source;

a light sensor electrically coupled to the power source and the light source;

wherein the light sensor activates the light source responsive to ambient light being within a pre-defined operational range; and

wherein the illumination system is placed into an interior of a dark area.

2. The illumination system of claim 1, wherein the light source includes a light array.

3. The illumination system of claim 1, wherein the light source includes a light-emitting diode.

4. The illumination system of claim 1, comprising a universal serial bus connection.

5. The illumination system of claim 4, wherein the universal serial bus connection charges the power source.

6. The illumination system of claim 4, wherein the universal serial bus connection facilitates programming of the power source.

7. The illumination system of claim 1, comprising a clip.

8. The illumination system of claim 1, comprising a ring.

9. The illumination system of claim 1, comprising a fastener.

10. A method for providing illumination to an interior of a dark area, the method comprising:

placing an illumination system into an interior of a dark area;

determining if ambient illumination is within a pre-defined operational range;

responsive to the ambient illumination being within the pre-defined operational range, activating a light source and deactivating the light source for a per-determined period of time;

emitting light from the light source in an amount greater than the pre-determined operational range.

11. The method of claim 10, wherein, after the emitting, assessing if the ambient light remains within the pre-defined operational range.

12. The method of claim 11, wherein the assessing comprises:

reactivating the light sensor after the pre-determined period of time;

deactivating the light source after the pre-determined period of time.

13. The method of claim 12, wherein, responsive to an assessment that ambient light remains in the pre-defined operational range, reactivating the light source and deactivating the light sensor for the pre-determined period of time.

14. The method of claim 12, wherein responsive to an assessment that ambient light is outside of the pre-defined operational range, deactivating the light source.

15. The method of claim 10, wherein the pre-determined period of time is on the order of 20 seconds.

16. The method of claim 10, wherein the light source includes a light-emitting diode.

17. The method of claim 10, wherein the light source includes a light array.

18. An illumination system comprising:

a power source;

a light source electrically coupled to the power source;

a first light sensor electrically coupled to the power source and the light source;

a second light sensor electrically coupled to the power source and the light source, the second light sensor oriented differently from the first light sensor;

wherein at least one of the first light sensor and the second light sensor activates the light source responsive to ambient light being within a pre-defined operational range; and

wherein the illumination system is placed into an interior of a dark area.

19. The illumination system of claim 18, wherein the light source is a light-emitting diode.

20. The illumination system of claim 18, comprising a universal serial bus connection.
