ABSTRACT:
An LED device radiator of an LED projection system, and more particularly, a radiator for cooling an LED device used in an LED projector is disclosed. The radiator includes a red LED device connected to a first substrate, a green LED device connected to a second substrate, a blue LED device connected to a third substrate, a first heat sink connecting a rear surface of the first substrate such that heat emitted from the red LED device is transferred to the first heat sink, and a second heat sink connecting a rear surface of each of the second and third substrate such that heat emitted from the green LED device and the blue LED device is transferred to the second heat sink.
