摘要:
An automobile signal lamp having at least one light emitting unit including a light source whose main light emitting direction substantially agrees with the irradiation axis of the automobile signal lamp, a first reflecting surface corresponding to at least irradiation direction side half of a parabolic reflecting surface obtained by rotating around said irradiation axis a parabola taking said light source as focal point, and a direction orthogonal to said irradiation axis of the automobile signal lamp as central line, and a second reflecting surface separated from said irradiation axis by a convenient distance respectively in the reflection direction of said first reflecting surface, disposed radially not to interfere each other, and reflecting light from said first reflecting surface in a direction parallel to said irradiation axis.
