Abstract

The luggage lighting system includes a piece of luggage and a lighting module coupled to the luggage. In some embodiments, the lighting module is a fiber-optic lighting module. The luggage includes an outer surface, and the lighting module includes a light diffuser coupled to the outer surface. In some embodiments, the light diffuser is a fiber-optic light diffuser. The lighting module also includes a light source, such as a laser or a light emitting diode (LED). When the light source is powered on, the output light is directed through the light diffuser. The light diffuser is configured to output single or multiple colors of light, easily observed by someone looking at the luggage. The luggage lighting system is particularly useful for identifying one'"'"'s luggage from surrounding pieces of luggage lacking the luggage lighting system.

Claims

1. A luggage lighting system comprising:

a. piece of luggage having an outer surface, wherein the outer surface includes one or more seams; and

b. a lighting module coupled to the piece of luggage, wherein the lighting module comprises a light source and a light diffuser, further wherein the light diffuser is coupled to the outer surface at or adjacent to, and in physical contact with, at least one of the one or more seams of the luggage, wherein the lighting module further comprises a proximity indicator that indicates that the luggage is in proximity of a remote control source.

2. The luggage lighting system of claim 1 wherein the light diffuser comprises an optical fiber.

3. The luggage lighting system of claim 2 wherein the optical fiber comprises a light diffusing optical fiber.

4. The luggage lighting system of claim 3 wherein the light diffusing optical fiber comprises one of a light diffusing glass fiber, a phosphor doped fiber, or a plastic diffusing fiber.

5. The luggage lighting system of claim 3 wherein the light diffuser further comprises a light transparent sleeve into which the light diffusing optical fiber is positioned.

6. The luggage lighting system of claim 5 wherein the light transparent sleeve comprises a light transparent plastic tube.

7. The luggage lighting system of claim 5 wherein the light transparent sleeve is sewn to the outer surface of the luggage.

8. The luggage lighting system of claim 3 wherein the light diffuser further comprises a light translucent sleeve into which the light diffusing optical fiber is positioned.

9. The luggage lighting system of claim 8 wherein the light translucent sleeve comprises a light translucent plastic tube.

10. The luggage lighting system of claim 8 wherein the light translucent sleeve is sewn to the outer surface of the luggage.

11. The luggage lighting system of claim 2 wherein the light diffuser further comprises a light translucent sleeve into which the optical fiber is positioned.

12. The luggage lighting system of claim 1 wherein the light source comprises one or more lasers coupled to the light diffuser.

13. The luggage lighting system of claim 1 wherein the light source comprises one or more light emitting diodes coupled to the light diffuser.

14. The luggage lighting system of claim 1 wherein the light diffuser is sewn to the outer surface of the luggage.

15. The luggage lighting system of claim 1 wherein further comprising an adhesive for coupling the light diffuser to the outer surface of the luggage.

16. The luggage lighting system of claim 1 wherein the light diffuser is configured to output a single color of light.

17. The luggage lighting system of claim 1 wherein the light diffuser is configured to output a series of different colored lights.

18. The luggage lighting system of claim 1 wherein the lighting module further comprises a power source to supply power to the light source and a control circuit to control the power supply and the light source.

19. The luggage lighting system of claim 18 wherein the power source comprises a battery, an energy harvesting element, or a combination of both a battery and an energy harvesting element.

20. The luggage lighting system of claim 1 wherein the light module further comprises an ON/OFF switch coupled to the control circuit to manually turn ON/OFF the light source.

21. The luggage lighting system of claim 1 wherein the lighting module further comprises a wireless receiver coupled to the control circuitry to wirelessly receive a signal to turn ON/OFF the light source.
