Patent ID: 7967475

Claim:
A Light Emitting Diode (LED) device radiator for an LED projection system comprising: 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 circuit board comprising a circuit element to drive the projection system; a first heat sink connected to a 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 connected to a surface of the second substrate and the third substrate such that heat emitted from the green LED device and the blue LED device is transferred to the second heat sink, wherein at least one of the first heat sink and the second heat sink comprises a radiating area expanding structure, wherein the radiating area expanding structure comprises a plurality of radiating plates, and wherein the radiating area expanding structure comprises a circuit element contact such that at least one of the plurality of radiating plates is in contact with the circuit element.
