PROBLEM TO BE SOLVED: To provide a safe headlamp for a vehicle capable of forming a light distribution pattern with high degree of freedom for shape.SOLUTION: A headlamp 1 for a vehicle includes excitation light sources (8a, 8B), a phosphor 11, scanning mechanisms (12, 13) configured to scan emission light (B11, B12) of the excitation light sources (8a, 8b) toward the phosphor 11, and a projection lens 14 configured to transmit the emission light (B11, B12) from the phosphor 11 to form a light distribution pattern La. In the headlamp 1 for a vehicle, a plurality of excitation light sources (8a, 8b) is provided, and an irradiation range of light incident to the phosphor 11 is different for each light source (8a, 8b).SELECTED DRAWING: Figure 2
【課題】形状の自在性が高い配光パターンを形成可能で安全な車両用前照灯の提供。【解決手段】励起光源(8a,8b)と、蛍光体11と、励起光源(8a,8b)の出射光(B11,B12)を蛍光体11に向けて走査する走査機構(12,13)と、蛍光体11からの出射光(B11,B12)を透過させて配光パターンLaを形成する投影レンズ14と、を有する車両用前照灯1において、複数の励起光源(8a,8b)が設けられ、蛍光体11に入射する光の照射範囲が、励起光源(8a,8b)毎に異なることを特徴とする車両用前照灯1。【選択図】図2
