LIGHT GUIDE MEMBER, LIGHTING APPARATUS USING THE LIGHT GUIDE MEMBER, AND METHOD OF FABRICATING THE LIGHT GUIDE MEMBER

摘要

Provided are a light guide member, a lighting apparatus including the light guide member, and a method of fabricating the light guide member. The light guide member comprises: a body, which is formed as a transparent plate, including a first surface and a second surface facing the first surface; and a plurality of dimple type optical controllers formed beneath at least one of the first surface and the second surface and having reflective surfaces that reflect light proceeding between the first and second surfaces of the body toward at least one of the first and second surfaces.

主权项

1. A method of fabricating a light guide member, the method comprising:
forming a plurality of protrusion molds on a template having a flat surface, each of the plurality of protrusion molds including a top surface that is wider than a bottom and a side surface under the top surface and inclined toward the top surface; forming a transparent half-processed light guide member having a cross-section corresponding to the plurality of protrusion molds by applying a transparent material on the template on which the plurality of protrusion molds are formed; and separating the transparent half-processed light guide member from the template and the plurality of protrusion molds so as to form the light guide member, which includes a first surface, a second surface facing the first surface, and a plurality of dimple type optical controllers, corresponding to the protrusion molds, in the first surface, wherein each of the plurality of dimple type optical controllers includes a reflective surface corresponding to the inclined side surface of each of the plurality of protrusion molds.
