Abstract

Lighting elements including organic light emitting devices (OLED) may be incorporated into incandescent, fluorescent, other conventional light bulbs and other lighting elements. Such lighting elements may be configured to produce colored or white light. The OLEDs may be fabricated from a plurality of polymers and/or include a plurality of chromophores.

Claims

1. A light bulb comprising:

an organic light emitting device; and

an organic light emitting device housing, the housing including at least two electrical contacts,

wherein the housing and electrical contacts may be use in a non-organic light emitting device light bulb socket.

2. The light bulb of claim 1, wherein the non organic light emitting device light bulb socket is a conventional incandescent or fluorescent light bulb socket.

3. The light bulb of claim 1, wherein the organic light emitting device emits white light upon excitation.

4. The light bulb of claim 1, wherein the organic light emitting device emits colored light upon excitation.

5. The light bulb of claim 1, wherein the organic light emitting device includes a plurality of chromophores.

6. The light bulb of claim 5, wherein the organic light emitting device emits white light upon excitation.

7. A light bulb comprising:

an organic light emitting device including a plurality of chromophores; and

an organic light emitting device housing, the housing including at least two electrical contacts,

wherein the housing and electrical contacts may be use in a conventional incandescent or fluorescent light bulb socket, and

wherein the organic light emitting device emits white light upon excitation.

8. A method of forming a light bulb comprising:

providing an organic light emitting device; and

housing the organic light emitting device in a housing including at least two electrical contacts,

wherein the housing and electrical contacts may be use in a non-organic light emitting device light bulb socket.

9. The method of claim 8, wherein the non organic light emitting device light bulb socket is a conventional incandescent or fluorescent light bulb socket.

10. The method of claim 8, wherein the organic light emitting device emits white light upon excitation.

11. The method of claim 8, wherein the organic light emitting device emits colored light upon excitation.

12. The method of claim 8, wherein the organic light emitting device includes a plurality of chromophores.

13. The method of claim 8, wherein the organic light emitting device emits white light upon excitation.
