Optical plate for lighting, and lighting apparatus using same

Abstract

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.
