Abstract

An apparatus is provided for illuminating the interior of an automotive passenger vehicle for ingress and egress. The apparatus comprises a lighting device integrated into the periphery of a sun visor or similar object. The lighting device is typically activated by a remote entry device, a door opening, or by an interior switch. The apparatus is particularly applicable where overhead interior lighting is impractical, such as in convertibles and other types of vehicles with removable tops. The lighting device may be customized for color and intensity, as well as for physical configuration. The apparatus can also be used in lieu of conventional interior roof lighting as a manufacturing cost reduction.

Claims

1. A system for illuminating the interior of a vehicle comprising:

at least one sun visor, the sun visor comprising;

an upper layer counted to a lower layer, and

a periphery formed between the upper layer and the lower layer;

a lighting device integrally formed within a majority of the periphery of the sun visor;

a power source configured to energize the lighting device; and

a switching device configured to electrically couple the power source to the lighting device, wherein the lighting device illuminates the vehicle interior when the switching device is activated.

2. The system of claim 1 wherein the lighting device provides an illumination level in the approximate range of 5 to 10 lumens per square meter for the interior of the vehicle.

3. The system of claim 2 wherein the lighting device comprises a series of lights integrated into a flexible ribbon configuration.

4. The system of claim 2 wherein the lighting device comprises a series of lights integrated into a tube configuration.

5. The system of claim 2 wherein the lighting device comprises a series of lights integrated into a channel configuration.

6. The system of claim 1 wherein the switching device is activated when a door of the vehicle is opened.

7. The system of claim 1 wherein the switching device is activated when a door of the vehicle is unlocked.

8. The system of claim 1 wherein the switching device is activated by an interior switch.

9. The system of claim 1 wherein the switching device is activated by an external control device.

10. The system of claim 2 wherein the lighting device has an adjustable color.

11. The system of claim 2 wherein the lighting device has an adjustable intensity.

12. A sun visor having an integrated lighting device for illuminating the interior of a vehicle, comprising:

a sun visor having an upper layer coupled to a lower layer, wherein a periphery is formed between the upper layer and the lower layer; and

a lighting device integrated within a majority of the periphery of the sun visor, wherein the lighting device provides a level of illumination for the vehicle interior in the approximate range of 5 to 10 lumens per square meter.
