The present invention relates to a lamp for vehicle which can obtains an ideal light distribution pattern using one light unit. The lamp for vehicle according to the present invention comprises: a first reflecting surface (11) in ellipse shape; a semiconductor light source (3) at a first focus (F11) or its vicinity of the first reflecting surface; and reflecting surfaces (12, 13, 14) in parabola shape controlling the reflected light (L2) from the first reflecting surface (11) to be reflected on the road as predetermined light distribution patterns (LP, HP, SP, WP). The second reflecting surface (12) forms light distribution pattern for high light degree (HP). The third reflecting surface 13 forms light distribution pattern for collection (SP) having the light distribution pattern for high light degree (HP). The fourth reflecting surface 14 forms light distribution pattern for diffusion (WP) overlapping the light distribution pattern for high light degree (HP) and the light distribution pattern for collection (SP). As a result, ideal light distribution patterns can be obtained using one light unit, and thus the traffic safety is greatly improved. |
