摘要: Conventional methods using two optical waveguide members are disadvantageous in cost because they require two optical waveguide members and pairs of their associated components. A linear lighting apparatus includes a rod-like optical waveguide member (100) formed by a transparent material, a light source placed near an end face of the optical waveguide member (100) in the longitudinal direction, and a light exit surface (101) formed on at least part of the optical waveguide member (100) in the longitudinal direction. A cross section of the optical waveguide member in the widthwise direction has a plurality of reflecting areas (102, 103) at positions to face a light exit surface (101) and a barrier (106) at a boundary portion between the reflecting areas (102, 103).
