摘要
To achieve light emission amount adjustment and diversification of each light emission part and to prevent the periphery of the light emission part and a light emission adjustment part from becoming conspicuous in appearance, in an optical duct light emission part structure including the light emission adjustment part.SOLUTION: A light emission adjustment part 2 is disposed at a separation opposing portion with a light emission part 1c, in a light guide part 1b between a light collection part 1a for light incidence and the light emission part 1c for light emission of an optical duct 1. The light emission adjustment part 2 is a both surface light reflection member which includes a reflection surface 2a on a light emission part opposing side and a reflection rear surface 2b on the opposite side from that. The light emission adjustment part 2 is disposed, for example, in a manner along the light propagation direction of the light guide part, the reflection surface 2a and the reflection rear surface 2b are made to be a mirror surface specification or a diffusion high reflection specification, and the light emission adjustment part includes a plurality of light passing hole parts 2c penetrating between them. Also, the light emission adjustment part 2 can use various types of shapes.SELECTED DRAWING: Figure 1
