Heat-sink for high bay LED device, high bay LED device and methods of use thereof

摘要

A heat sink comprises a base, primary fins on and vertically extending from the base, and a fin-free region on the base. The primary fins each have a first arm, a second arm, which meets the first arm to form a primary fin bottom, and a stem, which extends away from the primary fin bottom. The heat sink is particularly useful in a high bay LED device, with a molecular fan coating on the heat sink.
