VEHICLE HEADLIGHT

PROBLEM TO BE SOLVED: To provide a vehicle headlight suppressed in discomfort due to light color and also improved in visibility.SOLUTION: A vehicle headlight 100 is arranged on a vehicle 400, and includes: a first white light source 311 emitting first white light L1; a second white light source 312 emitting second white light L2 different from the first white light L1 by a feeling of contrast index by 10 or more; and a control part 104 controlling light intensity of the first white light L1 and light intensity of the second white light L2. Chromaticity of the first white light L1 and chromaticity of the second white light L2 are within a range of 5-step in the MacAdam ellipse. The first white light source 311 and the second white light source 312 are arranged on the vehicle headlight 100 so that the first white light L1 and the second white light L2 are superimposed on each other on a prescribed irradiation surface. The control part 104 subjects a light intensity ratio between the light intensity of the first white light L1 and the light intensity of the second white light L2 to a secular change.SELECTED DRAWING: Figure 2 【課題】光色による違和感が抑制され、且つ、視認性が向上される車両用前照灯を提供する。【解決手段】車両用前照灯１００は、車両４００に配置される車両用前照灯であって、第一白色光Ｌ１を照射する第一白色光源３１１と、第一白色光Ｌ１とは目立ち指数が１０以上異なる第二白色光Ｌ２を照射する第二白色光源３１２と、第一白色光Ｌ１の光強度及び第二白色光Ｌ２の光強度を制御する制御部１０４とを備え、第一白色光Ｌ１の色度及び第二白色光Ｌ２の色度は、ＭａｃＡｄａｍ楕円５ステップ範囲内であり、第一白色光源３１１及び第二白色光源３１２は、第一白色光Ｌ１及び第二白色光Ｌ２が所定の照射面で重畳するように、車両用前照灯１００に配置され、制御部１０４は、第一白色光Ｌ１の光強度と第二白色光Ｌ２の光強度との光強度比を経時変化させる。【選択図】図２
