Light emitting diode replacement lamp
View Patent ↗In various embodiments, an illumination device includes a housing, a power connector for connecting the illumination device to a power socket and receiving input power, a light emitter for direct illumination disposed within the housing, a circuit for regulating the input power and providing the regulated power to the light emitter, and a decorative illumination element for providing decorative illumination.
1. An illumination device comprising:
a housing;
a power connector for connecting the illumination device to a power socket and receiving an input power;
a first light emitter disposed within the housing;
a first optical component for directing illumination generated by the first light emitter outside the housing in a first direction;
a circuit for regulating the input power and providing the regulated power to the first light emitter;
a second light emitter for decorative illumination; and
a second optical component, separate from the first optical component, for directing decorative illumination therethrough outside the housing in a second direction, the second direction being different from the first direction.
2. The illumination device of claim 1 , wherein the second light emitter is disposed within the housing.
3. The illumination device of claim 1 , wherein the decorative illumination generated by the second light emitter is distinct from the illumination generated by the first light emitter.
4. The illumination device of claim 3 , wherein the decorative illumination and the illumination generated by the first light emitter are distinct in terms of an illumination color.
5. The illumination device of claim 3 , wherein the decorative illumination and the illumination generated by the first light emitter are distinct in terms of an illumination intensity.
6. The illumination device of claim 1 , wherein the second optical component guides decorative illumination generated from the secondary light emitter along substantially an entire length thereof.
7. The illumination device of claim 1 , further comprising a secondary circuit for regulating the input power and providing a regulated power to the secondary light emitter.
8. The illumination device of claim 7 , wherein the secondary circuit controls at least one of an intensity or a color of the secondary light emitter.
9. The illumination device of claim 7 , further comprising a circuit to respond to wireless commands for controlling the secondary light emitter.
10. The illumination device of claim 1 , wherein the first optical component is a total internal reflector.
11. The illumination device of claim 1 , further comprising a heat sink thermally connected to the light emitter for regulating a temperature of the first light emitter.
12. The illumination device of claim 1 , wherein the second optical component contains openings through which the decorative illumination exits the housing.
13. The illumination device of claim 1 , wherein the second direction is away from the first optical component.
14. A method of using an illumination device to provide a decorative illumination characteristic, comprising:
providing illumination from a first light emitter disposed within a housing
directing illumination generated by the first light emitter outside the housing in a first direction using a first optical component;
providing decorative illumination, distinct from the direct illumination, from a second light emitter; and
directing decorative illumination generated by the second light emitter through a second optical component outside the housing and in a second direction,
wherein the second optical component is separate from the first optical component and the second direction is different from the first direction.
15. The method of claim 14 , wherein the second direction is away from the first optical component.
16. The method of claim 14 , further comprising providing the illumination generated by the first light emitter through a substantially transparent cover attached to the housing.
17. The method of claim 14 , wherein the decorative illumination is directed through a substantially translucent shade of the housing.
18. The method of claim 14 , wherein at least one of an intensity or a color of the decorative illumination generated from the second light emitter is controlled by a circuit.
19. The method of claim 14 , wherein the secondary light emitter is responsive to wireless commands.
20. The method of claim 14 , wherein the decorative illumination is distinct from the illumination generated by the first light emitter in terms of at least one of emission direction, color, or intensity.
21. The method of claim 14 , further comprising directing the decorative illumination along substantially an entire length of the second optical component.
22. The method of claim 14 , wherein the decorative illumination is directed outside the housing through openings in the second optical component.
