化点为面 有效解决LED眩光和出光效率低问题

      大学材料科学系游波教授团队研制出的一种新型材料——光扩散涂层,在世博会上亮相。该材料能有效解决LED光源的眩光和出光效率低的问题。

  

      LED目前存在着许多不完善的地方,最致命的一个缺点就是其点光源的特性。LED灯发光时会产生强光点,无法用眼睛直视,若一直生活在高亮度的LED光源周围,LED光源所形成的强光点会瞬间影响视觉的判断力。短期内会产生眼睛的不适和疲劳,而长期使用更会产生永久性的伤害。

  

      免了LED产生的光污染危害,游波教授研发的光扩散膜将LED的点光源均匀转换成面光源,从而使光线形成漫反射,从而达到匀光的效果,这样整体的光源更均匀、柔和、饱满。记者了解到,光扩散膜不光可提高LED光线的利用率,增加LED的亮度,更可减少灯管使用量。一旦减少灯管数目,液晶屏幕的耗电量以及热能的产生均会大幅降低,对于绿色环保有所帮助。LED光扩散涂层,可替代目前使用的扩散膜,用于消除LED器件的眩光及点光源问题,可用于户外路灯及交通照明、大尺寸液晶面板以及笔记本电脑的背光源、建筑装饰照明、汽车用照明、家庭照明等。
