Patent number: 11754243Abstract: Multiple light sources are arranged in an array. A light guide member receives light emitted from the multiple light sources on its back face, and outputs the light thus received from its front face. The light guide member has a base portion such that its back face faces the multiple light sources and such that it extends in the array direction of the multiple light sources. Multiple back-face protrusions and multiple front-face protrusions are formed such that they protrude from the back face and the front face of the base portion.
