Title
(ZH) 一种导光板和LED光源组件
Abstract
(ZH)

本发明适用于照明领域,提供了一种导光板和LED光源组件,所述导光板包括:在中心面处设置的一荧光粉层、与所述荧光粉层相对的两个出光面以及位于所述荧光粉层的侧面的入光面;所述出光面与所述荧光粉层之间各处位置的折射率,随着与所述荧光粉层距离的增加而减小。本发明将LED光源置于荧光粉层的侧面,并使LED光源的光轴位于荧光粉层所在的平面;LED光源发出的光进入导光板,以近似余弦曲线的轨迹传播至荧光粉层激发荧光粉发光;荧光粉发出的光与LED光源发出的光混合后得到所需颜色的光,所需颜色的光直接从导光板的两个出光面提取出来,实现双面发光。
