Advanced Passive Cooling of High Power LED Light Engines

by Dr Aboudé Haddad, Director of Engineering, FrigoDynamics® Europe Ltd Introduction Conventional light sources have always been able to release heat to the ambient through infrared radiation, and convection in the case of Fluorescent. This mode of heat transfer typically does not require advanced cooling methods to facilitate the process.  LED sources however lose heat through conduction, which requires the additional knowledge of how to carry waste heat out of the LED efficiently in order to prevent system failure.  An overview of the different...
