Vehicular Illumination Lamp

摘要

A parabola type vehicular illumination lamp that forms a low-beam distribution pattern with a horizontal cut-off line at its upper end, including a reflector (34) formed in its lower reflection area (34a1) with a light non-incident area (34aL1) on which light from a light source bulb (32) is not incident since the light is blocked by a shade (36) provided in front of the light source bulb (32). The light non-incident area (34aL1) of the reflector (34) has an additional reflection portion (34aL1A) for reflecting light, which is from the light source bulb (32) and reflected by the upper reflection area (34au) of the reflector (34) and then reflected by the upper area (14u) of a translucent cover (14), in a direction below the horizontal cut-off line of the low-beam distribution pattern.
