Abstract
A light emitting device includes a plurality of light emitting diode stacks and a cooler. The plurality of light emitting diode stacks are each mounted to and cooled by the cooler. A light emitting device includes a plurality of light emitting diode stacks, a cooler, and a power supply. The plurality of light emitting diode stacks are each mounted to and cooled by the cooler, the power supply is configured to power the plurality of light emitting diode stacks, and the power supply is mounted to the cooler on an opposite side of the cooler relative to the plurality of light emitting diode stacks.
Claims16
A light emitting device, comprising:
- a plurality of light emitting diode stacks;
- and
- a cooler,
- wherein the plurality of light emitting diode stacks are each mounted to and cooled by the cooler,
- wherein the plurality of light emitting diode stacks are arranged to form an array including at least two rows and at least two columns.
A light emitting device comprising:
- a plurality of light emitting diode stacks;
- a cooler;
- and
- a power supply,
- wherein the plurality of light emitting diode stacks are each mounted to and cooled by the cooler,
- wherein the power supply is configured to power the plurality of light emitting diode stacks,
- wherein the power supply is mounted to the cooler on an opposite side of the cooler relative to the plurality of light emitting diode stacks, and
- wherein the power supply is configured to store electrical power received via power supply lines and discharge power to the plurality of light emitting diode stacks via high energy pulses.
A method for emitting light from a plurality of light emitting diodes, the method comprising:
- forming a plurality of emitter subassemblies, each emitter subassembly including:
- a plate-shaped light emitter having two sides and configured to emit light from an edge disposed between the two sides, and
- at least one plate-shaped submount attached to at least one side of the plate-shaped light emitter;
- forming a plurality of light emitting diode stacks by arranging a plurality of the emitter subassemblies disposed parallel to one another;
- mounting the plurality of light emitting diode stacks on a cooler to form an array of light emitting diode stacks;
- and
- forming direct bonded copper (DBC) substrate tracks configured to conduct electrical current through the plurality of light emitting diode stacks.
