Abstract

A white light LED-based lighting system configured for direct form, fit, and function replacement of existing incandescent, halogen, mercury vapor, high pressure sodium, and compact fluorescent systems is provided. The white light LED-based lighting system comprises a group of solid state light emitting diodes, electronics to activate the light emitting diodes, and an encapsulating housing enclosing the light emitting diodes and the activating electronics.

Claims

1. A lighting device for generating diffuse white light comprising:

a group of solid state light emitters, said group including light emitting diodes;

electronics to activate the solid state light emitters, wherein the electronics converts 120 volt 60 cycles per second alternating current to a steady state voltage direct current; and

an encapsulating housing enclosing the solid state light emitters and the activating electronics.

2. The device of claim 1 wherein the group of solid state emitters comprises a red, green, and blue light emitting diode.

3. The device of claim 1 wherein the encapsulating housing includes a diffusing element.

4. A lighting device for generating diffuse white light comprising:

a group of solid state light emitters, said group including light emitting diodes;

electronics to activate the solid state light emitters, wherein the electronics converts and regulates a steady state voltage, direct current input to the electronics, to the solid state light emitters; and

an encapsulating housing enclosing the solid state light emitters and the activating electronics.

5. A lighting device for generating diffuse white light comprising:

a group of solid state light emitters, said group including ultraviolet light emitting diodes;

electronics to activate the solid state light emitters, wherein the electronics converts and regulates a steady state voltage, direct current input, to the electronics, to the solid state light emitters;

phosphors which absorb the output of the ultraviolet light emitting diodes and emit visible light; and

an encapsulating housing enclosing the solid state light emitters and the activating electronics.

6. The device of claim 5, wherein the phosphors emit respectively red, green, and blue light.
