Description

LED灯管外壳材料
技术领域
本发明涉及材料领域，尤其涉及LED灯管外壳材料。
背景技术
LED光源属于点光源，点光源光照范围窄且会人眼产生眩光的影响，一般通过灯罩的光散射作用，将点光源转变成面光源，以利于人们的日常使用。聚碳酸酷材料广泛用于灯罩材料中，为赋予聚碳酸酷光散射功能，人们将一些具有不同折射率的聚合物或无机粒子作为分散相键入到连续相得热塑性树脂中，这样不仅影响了其透光性能，而且会使灯罩材料的热膨胀系数增大几倍甚至几十倍。LED芯片体积非常小，一般照明用的LED灯中采用IW的芯片甚至更大功率的芯片，半导体有机硅芯片的热膨胀系数在2 .4-6*10-6 K-1之间，其产生的热流密度可达到106 w/m2以上。如果热量没能及时地传导出去，大量热量的累积会使LED芯片的结温升高，从而导致芯片的发光效率降低，光品质下降。
