Abstract:
PROBLEM TO BE SOLVED: To improve a lighting device having a plurality of semiconductor light sources at low cost. SOLUTION: In the lighting device having a plurality of semiconductor light sources arranged on a support body, each of the light of the light sources enters into a predetermined light guide in a fixed angle for the normal plane of the support body so as to couple thereto. The light guide is constructed so as to equip a light reflection plane and a light emission plane in which the envelope surface of the light reflection plane forms a curved surface segment.
