HEAT EXCHANGER FOR LED LIGHT FIXTURE

摘要

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.
