<P>PROBLEM TO BE SOLVED: To provide a headlamp for a vehicle, which can improve visibility of peripheral pedestrians and obstacles or the like in a traffic environment. <P>SOLUTION: The headlamp for a vehicle including an LED light source radiating light in a white color range, includes: a first headlamp unit structured so as to condense in a periphery of an intersection of a horizontal line and vertical line, and form a hot zone light distribution pattern including an elbow line; and a second headlamp unit structured so as to be superposed on the hot zone light distribution pattern and form a diffusion light distribution pattern diffused horizontally. A color temperature of the LED light source is 4,500-7,000 [K], and four coordinate values indicating prediction of how four colors (red, green, blue, yellow) are viewed are included in circle ranges with a center of coordinate values R(41.7, 20.9), G(-39.5, 14.3), B(8.8, -29.9), Y(-10.4, 74.2) on a coordinate system corresponding to a CIE1976L*a*b* space. <P>COPYRIGHT: (C)2011,JPO&INPIT |
