Abstract:
Provided are a lighting member and a lighting system with high light efficiency, having a structure capable of improving safety at a corner or an external corner in a living space while maintaining the appearance of the living space. A light beam is irradiated from a first emitting portion (LD1) and passes near the inner protrusion of a holding member (HL). The light beam is incident upon an incidence plane (IP) at an angle δ, and the incidence plane (IP) is inclined so that the light beam is refracted. The light beam is output from an output plane (OP) at an angle γ, which is less than the angle δ.
