发明名称 VEHICULAR HEADLAMP
摘要 PROBLEM TO BE SOLVED: To solve the problem in which a conventional vehicular headlamp cannot reduce a yellowish portion in a light distribution pattern.SOLUTION: This invention includes: a semiconductor type light source 2; a projection lens 3; and a reflector 4. A reflection surface of the reflector 4 has a first reflection surface 41 and a second reflection surface 42. The first reflection surface 41 has a first focal point F11 located in or in the vicinity of the semiconductor type light source 2, and a second focal point F12 located further on the semiconductor type light source 2 side than a focal point F3 of the projection lens 3. The second reflection surface 42 has a first focal point F21 located in or in the vicinity of the semiconductor type light source 2, and a second focal point F22 located further on the projection lens 3 side than the focal point F3 of the projection lens 3. As a result of this, this invention can reduce a yellowish portion in a light distribution pattern.SELECTED DRAWING: Figure 1
