TRANSPARENT PLASTIC PLATE FOR LIGHT EMITTING DEVICE LIGHT EMITTING DEVICE AND METHOD FOR MANUFACTURING TRANSPARENT PLASTIC PLATE FOR LIGHT EMITTING DEVICE

摘要

A transparent plastic plate for a light emitting device according to a first aspect of the present invention is a transparent plastic plate for a light emitting device in which a plurality of light reflection grooves are formed along the traveling direction of light so that light irradiated from a light source installed on the side is reflected and refracted, The depth of the plurality of light reflection grooves gradually increases from a portion adjacent to the light source toward the central portion of the transparent plastic plate, and a white layer of a predetermined pattern is formed on the inner surface of the light reflection grooves.
