摘要:
A unitary light guide plate includes a light exit plane, a thick portion located substantially on a center portion of the light exit plane, thin end portions formed on both sides of the thick portion, a half portion of a parallel groove formed on a backside of the light exit plane to accommodate linearly arranged light sources, inclined back portions arranged so as to become thinner from the thick portion to the thin end portions, and scattering means for scattering light entering from the light sources accommodated in the parallel groove into the thin end portions and propagated through the inclined back portions toward the thick portion. A light guide plate unit has two or more of the unitary light guide plates coupled together in such a way that respective light exit planes are arranged to form a same plane.
摘要(中):
单一导光板包括光出射平面,大致位于光出射面的中心部分的厚壁部分,形成在厚壁部分的两侧的薄端部,形成在背面的平行凹槽的半部分 光出射平面以适应线性布置的光源,从厚部到薄端部布置成更薄的倾斜后部,以及用于将从容纳在平行凹槽中的光源进入的光散射到薄端部的散射装置 并且通过倾斜的后部向着厚的部分传播。 导光板单元具有以相应的光出射平面布置以形成相同平面的方式联接在一起的两个或多个单一导光板。
