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