e to loss of ATR leads to too much light, choose the appropriate transition of the refractive index of the epoxy resin to improve die efficiency of the light emitted. Used as a form of epoxy resin shell must have moisture resistance, insulation, mechanical strength, the die emits light on the refractive index and transmission rate.
Select a different refractive index of packaging materials, packaging geometry of the photon escape efficiency is different, the angular distribution of luminous inte
