Abstract

A vehicle interior lighting assembly includes a housing configured to contain lighting components, a lens through which light may be projected from the housing, and a light source including a flexible sheet including one or more light emitting diodes (LEDs). The flexible sheet includes a first, larger portion disposed at a first orientation at an oblique angle with respect to the lens, and a second, smaller portion disposed at a second orientation that is substantially aligned with the lens. At least one of the one or more LEDs is disposed on the second, smaller portion of the flexible sheet.

First claim

We claim:

1. A vehicle interior lighting assembly, comprising:
a housing configured to contain lighting components;
a lens through which light may be projected from the housing; and
a light source including a flexible sheet including one or more light emitting diodes (LEDs);
wherein the flexible sheet includes a first, larger portion disposed at a first orientation at an oblique angle with respect to the lens, and a second, smaller portion disposed at a second orientation that is substantially aligned with the lens; and
wherein at least one of the one or more LEDs is disposed on the second, smaller portion of the flexible sheet;
wherein the one or more reflective components are movable to augment light projected from the lighting assembly.

2. The lighting assembly of claim 1 , wherein the second, smaller portion of the flexible sheet has a surface area that is smaller than the surface area of the first, larger portion of the flexible sheet.

3. The lighting assembly of claim 2 , wherein the second, smaller portion of the flexible sheet is a projection extending from the first, larger portion of the flexible sheet.

4. The lighting assembly of claim 1 , wherein the housing extends at an oblique angle with respect to the lens.

5. The lighting assembly of claim 1 , further including one or more reflective components configured to reflect additional light from the LEDs through the lens.

6. A vehicle interior lighting system, comprising:
a first vehicle interior lighting assembly including:
a lens through which light may be projected; and
a light source including a flexible sheet including one or more light emitting diodes (LEDs) arranged to project light through the lens;
wherein the flexible sheet includes a first, larger portion disposed at a first orientation at an oblique angle with respect to the lens, and a second, smaller portion disposed at a second orientation that is substantially aligned with the lens; and
wherein at least one of the one or more LEDs is disposed on the second, smaller portion of the flexible sheet; and

a controller including a device processor and a non-transitory computer readable medium including instructions executable by the processor to control operation of the lighting assembly.

7. The system of claim 6 , further including a second vehicle interior lighting assembly including the same general components as the first vehicle interior lighting assembly, including a lens and a flexible sheet including one or more LEDs;
wherein the computer readable medium of the controller includes instructions, executable by the processor, to control the first lighting assembly based on output of the second lighting assembly in real time.

8. The system of claim 7 , wherein the computer readable medium includes instructions for receiving lighting performance information from the second lighting assembly and controlling operation of the first lighting assembly based on the performance information regarding the second lighting assembly.

9. The system of claim 7 , further including a sensor separate from the second lighting assembly configured to detect the output of the second lighting assembly;
wherein the computer readable medium includes instructions for receiving lighting performance information regarding the second lighting assembly from the sensor and controlling operation of the first lighting assembly based on the performance information regarding the second lighting assembly.

10. The system of claim 6 , wherein the first lighting assembly includes one or more reflective components configured to reflect additional light from the LEDs through the lens.

11. The system of claim 10 , wherein the computer readable medium includes instructions, executable by the processor, for controlling movement of the one or more reflective components to augment output of the first lighting assembly.

12. The system of claim 6 , further including a reflective component separate from the first lighting assembly configured to reflect light from the first lighting assembly and redirect the light to a predetermined target area.

13. The system of claim 6 , wherein the computer readable medium includes instructions, executable by the processor, for controlling movement of the reflective component to augment output of the first lighting assembly.
