Thermal management is one of the key technologies for high-power light emitting diodes (LEDs) packaging, which can greatly affect the luminous efficiency, brightness and reliability of LED devices.Actually, there are many factors which involving in the thermal management of LED package, including LED chip structure, packaging materials (thermal interface materials and heat spreader), packaging structure and packaging processing.In this talk, some packaging materials for thermal management of HP LED devices were introduced, and some factors which affected the thermal resistance of high-power LED devices are analyzed in detail, it indicating that thermal management of LED package is a systematic concept, each thermal resistance in thermal path should be considered integrated and synthetically, decreasing only one of them cannot solve the problem of thermal management of LEDs.
