摘要
Abstract
The research found the effect of high-density-LED property from different optical windows.Through thermal simulation and physical property test of actual samples,the influence from different windows on performance and reliability was compared.It was found that optical window can increase the cooling channel of LED chips,and also affect reliability of LED.Optical windows could cause part of light energy loss,especially with the fluorescent transformation function of the window.It could product heat due to transformation of fluorescent,and the results of heat producting is different with different substrate materials.Experimental results show that the material with fluorescent transformation rate and high thermal conductivity could effectively reduce the fluorescent transformation of heat,speed up the fluorescent transformation heat derived,improve the luminous efficiency and reliability of device when it is used in to high density of LED device.关键词
