Abstract
A lighting device having a light emitting diode (LED). The device includes a metal substrate having a surface. A dielectric coating layer is superimposed on the surface of the metal substrate. A light emitting diode (LED) is supported on the dielectric coating layer. The metal substrate serves as a heat sink for the heat emitted by LED during operation.
Claims18
An apparatus for use as a light emitting diode (LED) lighting device, comprising:
- a metal substrate having a surface;
- a dielectric coating layer superimposed on the surface of the metal substrate;
- an electric circuit disposed upon the coating layer;
- and
- a light emitting diode (LED) mounted upon the substrate and electrically connected to the circuit, whereby the metal substrate serves as a heat sink for the LED.
A method for making a light emitting diode (LED) light engine, comprising:
- coating a metal substrate with a dielectric coating material;
- and
- mounting an LED on the coated metal substrate to thereby form the light emitting diode (LED) light engine, whereby the metal substrate is a heat sink for the LED.
An apparatus for use as a light emitting diode (LED) light engine, comprising:
- means for coating a metal substrate with a dielectric coating material;
- and
- means for mounting an LED on the coated metal substrate to thereby form the light emitting diode (LED) light engine, whereby the metal substrate is a heat sink for the LED.
