大功率集成LED光转换光源的研制

介绍了一种应用远程激发技术的大功率集成LED光转换光源,通过使用固晶区无绝缘层的镜面铝基板进行集成封装蓝光LED光源,即COB光源。所制蓝光光源与远程激发荧光粉模块结合制成LED光转换光源。利用镜面铝基板的高导热系数,解决多种LED封装形式下芯片点亮温度过高、光源衰减快的问题。采用LED荧光高分子模块与蓝光芯片分离结合的远程激发技术制成白光光源,解决荧光粉分布不均、热老化、色偏移问题。通过与传统粉胶封装方式制得的大功率集成LED器件比较测试,该种光源具有防眩光、光色均匀度高、长寿命、节能和环保的优点,从而具有更广泛的用途。

Research and Manufacturing of High Power Integrated LED Light Conversion Source

A high-power integrated LED light conversion light source applying remote excitation technique was introduced.The blue LED that is COB package blue LED through mirror-free aluminum plate without insulating layer in solid crystal area to develop to LED light conversion source with remote excited phosphor module.The problems of lots of package chip light temperature too high and light attenuation too fast were solved by using high thermal conductivity coefficient of mirror aluminum plate.And it is an effective solution to the issue of uneven distribution of phosphor,thermal aging of phosphor and color offset.Compared with traditional phosphor and resin glue package pattern,the high-power LED has the advantages of anti-dazzle,high light color degree of homogeneity,long life,energy saving,and environmental protection,so as to achieve more widely uses.
