摘要: A reflector (14) has a reflective surface (22) for reflecting light from emitter (12). At least an opening part (36) of the cross-sectional shape formed such that angle by optical axis (CL) and tangent (TL) passing through given point on is gradually increased as position gets closer to end (28) (22).
