Abstract
A heat exchange system for an LED light fixture is provided. The heat exchange system includes an enclosure 4, a heat sink 9 positioned inside of and spaced apart from said enclosure 4, and a fan positioned inside of and spaced part from said enclosure 4. Heat is first transferred from LEDs 1 to heat sink 9. Heat is then transferred from heat sink 9 to the air within said enclosure 4 aided by fan 10. Heat is then transferred from the air inside of enclosure 4 to said enclosure 4 and then to outside ambient air. The enclosure 4 may be open (unsealed) or closed (sealed from a surrounding environment). The heat exchange system may be constructed from relatively simple and inexpensive components.
Claims20
A heat exchange system for a light emitting diode (LED) light fixture, comprising:
- an enclosure at least partially surrounding at least one LED;
- a heat sink positioned inside of and spaced apart from said enclosure, the heat sink configured to transfer heat away from the at least one LED;
- and
- a fan positioned inside of and spaced part from said enclosure, the fan configured to transfer heat away from the heat sink.
A thermal management system for an LED light fixture, the system comprising:
- a first heat exchanger to remove heat from LEDs to air within an enclosure that at least partially surrounds the LEDs;
- and,
- a second heat exchanger to transfer heat from the air within the enclosure to air outside of said enclosure.
A heat exchange system for an LED light fixture, the system comprising:
- an enclosure comprising a peripheral wall that comprises a pleated structure;
- a heat sink positioned inside of and spaced apart from the enclosure;
- a fan positioned inside of and spaced part from the enclosure and mounted one of on and proximal to a first side of the heat sink;
- and,
- a baffle positioned inside of and spaced part from the enclosure and positioned one of proximal and abutting to the fan on the first side of the fan;
- wherein heat exchange system is closed from an external environment.
