Patent ID: 8324815

Claim:
An LED lighting system, comprising: a light emitting diode (LED) bulb base; a front end power supply electrically coupled to the LED bulb base; an over-mold encapsulating the front end power supply; a solid state active heat sink electrically coupled to and driven by the front end power supply; a plurality of light-emitting diodes thermally cooled by the solid state active heat sink; a digital micro-mirror device for receiving a light input from the light-emitting diodes, wherein the digital micro-mirror device is configured to control direction, intensity, or color of the light output of the LED lighting system; a prismatic mechanism to convert the color of the light emitted from the light-emitting diodes prior to inputting the light into the digital micro-mirror device; and an optic having a plurality of quantum dots disposed therein, wherein the quantum dots are configured to produce polychromatic light after being activated by light output from the digital micro-mirror device.
