Title:
LIGHT GUIDE BODY, LUMINAIRE USING THE SAME AND MOLD FOR MANUFACTURING LIGHT GUIDE BODY
Document Type and Number:
Japanese Patent JP2018046019
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a light guide body capable of corresponding to a light source to suppress unevenness generated in the light guide body, a luminaire using the light guide body, and a mold for manufacturing the light guide body.SOLUTION: A light guide body is configured to make light incident from a predetermined position and guide the light, and has a light extraction part configured to emit, to the outside of the light guide body, light having been propagated in the light guide body. The light extraction part has a light guide part formed into a convex or concave shape between adjacent light extraction parts, and configured to reflect light and guide it. For a portion connecting between the light guide part and the light extraction part as a connection part, the light extraction part and the connection part has a surface with minute irregularities.SELECTED DRAWING: Figure 1(a)
