Abstract

A lighting apparatus is disclosed. The lighting apparatus comprises a circuit configured to be disposed in a panel defining a cavity forming an opening. The circuit comprises a light source in communication with a controller and configured to emit a first emission. A photoluminescent portion is disposed proximate the light source and is configured to convert at least a portion of the first emission to a second emission. The second emission is output from the cavity to provide ambient light.

Claims (23)

1. A lighting apparatus comprising:

a circuit comprising an exposed conductive portion conductively connected to an isolation terminal configured to be disposed in a panel defining a cavity forming an opening;

a light source configured to emit a first emission; and

a photoluminescent portion disposed proximate the light source and configured to convert at least a portion of the first emission to a second emission, wherein the second emission is output from the cavity.

2. The lighting apparatus according to claim 1 , wherein the photoluminescent portion is disposed along a length of the circuit.

3. The lighting apparatus according to claim 1 , wherein the first emission corresponds to a first color of light and the second emission corresponds to a second color of light.

4. The lighting apparatus according to claim 3 , wherein the second color is more acutely visible than the first color.

5. The lighting apparatus according to claim 1 , wherein the photoluminescent portion is disposed on a surface of the circuit.

6. The lighting apparatus according to claim 1 , wherein the circuit is disposed on a first surface of the cavity and the photoluminescent portion is disposed on a second surface of the cavity.

7. The lighting apparatus according to claim 1 , wherein the exposed conductive portion is oriented proximate the opening providing a path for an electrical discharge to protect the light source from the electrical discharge.

8. A lighting apparatus comprising a circuit configured to be disposed in a panel defining a cavity, the circuit comprising:

a light source and configured to emit a first emission through at least a portion of the cavity to a photoluminescent portion, wherein the photoluminescent portion is configured to convert at least a portion of the first emission to a second emission that is output from the cavity, wherein the circuit comprises an exposed conductive portion conductively connected to an isolation terminal.

9. The lighting apparatus according to claim 8 , wherein the first emission corresponds to a first color of light and the second emission corresponds to a second color of light.

10. The lighting apparatus according to claim 9 , wherein the first color corresponds to a shorter wavelength of light than the second color.

11. The lighting apparatus according to claim 9 , wherein the second color corresponds to a plurality of wavelengths of light.

12. The lighting apparatus according to claim 8 , further comprising a controller operable to adjust an intensity of the first emission such that at least a portion of the first emission is output from the cavity.

13. The lighting apparatus according to claim 12 , wherein the first color is blended with the second color to generate a third color in response to the output of the portion of the first emission.

14. The lighting apparatus according to claim 12 , wherein a color hue of the third color output from the cavity changes in response to the intensity of the first emission.

15. A lighting apparatus comprising a circuit configured to be disposed in a panel defining a cavity, the circuit comprising:

a light source and configured to emit a first emission through at least a portion of the cavity to a photoluminescent portion, wherein photoluminescent portion is configured to convert at least a portion of the first emission to a second emission that is output from the cavity, wherein the photoluminescent portion further comprises a plurality of light dispersal features formed in a elongated pyramid shape extending from a surface of the circuit.

16. The lighting apparatus according to claim 15 , wherein the photoluminescent portion is disposed on the surface of the circuit.

17. The lighting apparatus according to claim 15 , wherein the plurality of light dispersal features is configured to spread the first emission along the photoluminescent portion.

18. The lighting apparatus according to claim 15 , wherein the circuit comprises an exposed conductive portion conductively connected to an isolation terminal.
