Title:
LIGHT-SPLITTING PLATE
Document Type and Number:
WIPO Patent Application WO/2023/284239
Kind Code:
A1
Abstract:
Disclosed in the present invention is a light-splitting plate. The light-splitting plate is located above a light source, and comprises a light-splitting plate structure. The light-splitting plate structure is fixedly connected to the light-splitting plate, and the light-splitting plate structure comprises a triangular pyramid light-splitting structure and a pyramid light-splitting composite arrangement structure, wherein the triangular pyramid light-splitting structure is determined according to the angle of the top end of a triangular pyramid and the vertical distance from the vertex of the triangular pyramid to an outer surface of the upper end of a light-splitting plate main body. Further provided is a light-splitting plate, comprising a first light-splitting plate structure and a second light-splitting plate structure, wherein a triangular pyramid light-splitting structure thereof is determined according to the vertical distance from the vertex of a triangular pyramid to the light-splitting plate and the length of a side extending from the vertex of the triangular pyramid to the light-splitting plate. By means of the present invention, incident light rays are continuously reflected in a microstructure, so that not only do the light rays enter a dark area to achieve good shielding of a light source dot matrix, but the light transmittance of the light-splitting plate can also be effectively improved.
