Abstract
A cooling system for a light emitting diode (“LED”) assembly includes a fluid configured to absorb heat at the LED assembly, a heat exchanger coupled to one or more substrates of the LED assembly, where the heat exchanger is configured to exchange heat between the LED assembly and the fluid, and a pump configured to circulate the fluid along the LED assembly and the heat exchanger, where the fluid exhibits a turbulent flow at the LED assembly, the heat exchanger, or both, while circulated by the pump.
Claims20
A cooling system for a light emitting diode (“LED”) assembly, comprising:
- a fluid configured to absorb heat at the LED assembly;
- a heat exchanger coupled to one or more substrates of the LED assembly, wherein the heat exchanger is configured to exchange heat between the LED assembly and the fluid;
- and
- a pump configured to circulate the fluid along the LED assembly and the heat exchanger, wherein the fluid exhibits a turbulent flow at the LED assembly, the heat exchanger, or both, while circulated by the pump.
A light emitting diode (LED) device, comprising:
- an LED assembly;
- and
- an enclosure configured to house the LED assembly, wherein an outer annular passage is formed between the LED assembly and the enclosure, wherein the outer annular passage is configured to enable circulation of a fluid along the LED assembly and through a heat exchanger to absorb heat from the LED assembly, wherein the LED assembly is configured to be immersively disposed within the fluid, wherein the LED assembly is configured to emit light through the fluid and through the enclosure, and wherein the fluid exhibits a turbulent flow while circulating through the LED assembly.
A light emitting diode (“LED”) assembly, comprising:
- a plurality of LED arrays, wherein each LED array of the plurality of LED arrays comprises:
- a substrate;
- and
- a plurality of LEDs coupled to the substrate;
- and
- a heat exchanger coupled to the substrate of each LED array of the plurality of LED arrays, wherein the heat exchanger is configured to exchange heat between the plurality of LED arrays and a fluid, wherein the fluid exhibits a turbulent flow at the heat exchanger.
