LIGHT PANEL WITH LIGHT DIFFUSION PARTICLES

摘要

PURPOSE: A light panel with light diffusion particles is provided to concentrate light around a view angle distribution according to the direction of an optical pattern while improving the brightness and the uniformity of the brightness. CONSTITUTION: A pattern layer(110) has a plurality of optical patterns on one side. A plurality of optical diffusion particles(120) are dispersed inside an optical pattern of the pattern layer. The optical diffusion particles have a hollow shape and having an outer side which is formed with a material having a reference rate lower than the pattern layer.
