摘要
Abstract
Fluorescence and packaging material are briefly introduced in this paper. Then the novel transparent phosphor ceramic shell of white LED researched by Bright Crystals Technology, Inc. is reported. Using MgAl2O4 powder mixed with phosphor commercial or homemade, the transparent phosphor ceramic was sintered, machined, packaged and tested. Because of the uniform distribution of the phosphor in transparent ceramic, this method avoids the precipitation of phosphor in resin and improves the uniformity of the light. Owing to higher thermal conductivity than resin, ceramic material can accelerate the cooling of LED. Meanwhile, the transparent ceramic has excellent mechanical performance; it can be used to package LED directly. This research will extend the application field of LED.关键词
