PROBLEM TO BE SOLVED: To provide a linear lighting device capable of forming a linear light of high illuminance free from non-uniform brightness, using efficiently a light emitted from a light source.SOLUTION: A light emitting part 12 of the light source 11 is formed into a band shape extended linearly. An optical member 3 for converting the emitted light from the light emitting part 12 into the linear light is constituted to include a light guide part 20 with an incident face 21 extended oppositely to the light emitting part 12, a cylindrical lens part 22 formed integrally with the light guide part 20 in an opposite side of the incident face 21, and a reflecting optical part 23 formed integrally in short-directional both sides of the light guide part 20. A reflecting face 32 extended adjacently to a side face 24 is formed further in an outgoing side of the reflecting optical part 23, by a frame 4 surrounding the optical member 3. Thus, the linear light of high illuminance free from non-uniform brightness is formed, using efficiently the light emitted from the light source 11. |
