PROBLEM TO BE SOLVED: To provide a technology improving visibility of a vehicular lighting tool.SOLUTION: A vehicular lighting tool 200 according to one embodiment includes: an LED light source 18; a laser beam source whose luminance is higher than the LED light source 18 and irradiation area is narrower than the LED light source; and an optical system that forms a light distribution pattern with light emitted from the LED light source 18 and laser beam source. The LED light source 18 and the optical system may be constituted so as to form a light distribution pattern for passing-by beam. The laser beam source and the optical system may be constituted so as to form a high-luminance area being in the vicinity of the central part of a light distribution pattern and having a cutoff line.

    【課題】車両用灯具の視認性を向上する技術を提供する。【解決手段】ある態様の車両用灯具200は、LED光源18と、輝度がLED光源18より高く、照射領域がLED光源より狭いレーザ光源と、LED光源18およびレーザ光源から出射した光により配光パターンを形成する光学系と、を有する。LED光源18および光学系は、すれ違いビーム用の配光パターンを形成するように構成されていてもよい。レーザ光源および光学系は、配光パターンの中央部近傍であってカットオフラインを有する高輝度領域を形成するように構成されていてもよい。【選択図】図10
