Abstract
A composite diffuser structure includes a transparent plate, a lenticular structure and a plurality of reflecting structures. The transparent plate has a light-in surface and a light-out surface. The lenticular structure has a plurality of lenticular lenses disposed on the light-out surface. The reflecting structures are disposed on the light-in surface. Each lenticular lens has a first width. An opening is formed between two adjacent reflecting structures and below the lenticular. Each opening has a second width. The light beams enter into the transparent plate from the openings to the lenticular so that the parallelism of the light beams are improved. Furthermore, a diffusing layer is disposed on the lenticular structure so as to optimize the quality of the light beams.
