Optical plate for lighting, and lighting apparatus using same

摘要

The present invention relates to an optical plate for lighting capable of improving the brightness of light emitted from a light source and adjusting a viewing angle to alleviate side glare phenomenon. The present invention also relates to a lighting. The purpose of the present invention is to provide a structure in which a light-diffusing member and an optical viewing angle adjusting member can independently function; an integrated optical plate for lighting, wherein the thickness of the optical plate for lighting is reduced by the lamination of a light-diffusing member, a transmission layer, and an optical viewing angle adjusting member; a lighting apparatus using thereof. In order to achieve this purpose, the technical properties of an optical plate for lighting according to the present invention have a transmission layer between a light-diffusing member and an optical viewing angle adjusting member while a light-diffusing member, a transmission layer, and an optical viewing angle adjusting member are laminated together.

主权项

1. An optical plate for lighting, comprising:
a light-diffusing member that diffuses light; an optical viewing angle adjusting member that controls a pathway of the diffused light to create a uniform viewing angle; a transmission layer placed between the light-diffusing member and the optical viewing angle adjusting member, wherein the light-diffusing member, the optical viewing angle adjusting member, and the transmission layer are laminated together, and wherein the transmission layer is an air layer formed by multiple spacers and placed between the light-diffusing member and the optical viewing angle adjusting member.
