LED illumination device with heat sink having a portion of heat fins exposed to axial forced flow from a cooling fan

摘要

An LED illumination device includes an LED device; a base having a concavity for receiving the LED device; a heat sink including a plate coupled to the base and a plurality of fins extending from a surface of the plate opposite the base, the fins extending laterally beyond sides of the plate; a cooling fan for forcing air over the fins; and a casing housing the LED substrate, the base, the heat sink, and the cooling fan.
