<P>PROBLEM TO BE SOLVED: To provide a lighting system for widely radiating light in road lighting. <P>SOLUTION: This lighting system 100 has a light source part 1, a hollow light emitting part 4, and a reflecting surface 5. The hollow light emitting part 4 has a box-type shape, guides light incident from a light source 2 to one end part 4a into the other end part 4b, and emits a part of light to the outside from a light emitting side surface 4c over the length direction. The reflecting surface 5 is projected to an inner circumferential wall surface 7 of the hollow light emitting part 4, makes bend light incident from one end part 4a, and emits to the outside from the light emitting side surface 4c. The reflecting surface 5 is installed on one surface of a light distribution control reflecting member 6 having a triangular pyramid shape made of an aluminum plate or the like, inclined so as to face one end part 4a and the light emitting side surface 4c, and arranged across two adjacent reflecting walls 4d. <P>COPYRIGHT: (C)2004,JPO |
