Description
(作用)本願の車両用前照灯によれば、投影レンズの湾曲する像面よりも小さな曲率を有し、かつ像面と同一方向に湾曲する蛍光体に走査光を透過させることにより、車両前方の平面に配光パターンを形成する走査光の焦点は、走査位置が走査範囲の中央位置から左右端部に近づくにつれて徐々にぼやけ、湾曲した蛍光体を透過して車両前方の平面に照射される走査光の光束密度は、走査位置が走査範囲の中央位置から左右端部に近づくにつれて減少する。
蛍光体31は、前面が凸面であり、後面が平面となる矩形形状に形成されて角穴32aの先端部近傍に固定される。また、蛍光体31は、前後方向の厚さが光軸L0と交差する中央部31aで最も厚く、かつ中央部31aから左端部31b及び右端部31cに向けてそれぞれ同じ割合で徐々に薄くなるよう形成される。蛍光体31は、第1実施例の蛍光体9と同様に励起光源10の発する色に応じて黄色、黄色かつ青色、または赤色かつ緑色かつ青色(RGB)の少なくとも3色を有する蛍光体として形成され、励起光源10の出射光を白色光にする。

- 励起光源と、前記励起光源による出射光を所定の方向に向けて、sinカーブに基づいた動作で走査する走査機構と、投影レンズと、前記走査機構と投影レンズの間に設けられて走査機構による走査光を投影レンズに向けて透過させる蛍光体とを有する車両用前照灯において、
前記蛍光体が、前記投影レンズの湾曲する像面に対して逆向きに湾曲する湾曲体として形成され、かつ蛍光体の左右中央位置が、前記投影レンズの湾曲する像面の左右中央位置近傍に配置されたことを特徴とする車両用前照灯。 - 励起光源と、前記励起光源による出射光を所定の方向に向けて、sinカーブに基づいた動作で走査する走査機構と、投影レンズと、前記走査機構と投影レンズの間に設けられて走査機構による走査光を投影レンズに向けて透過させる蛍光体とを有する車両用前照灯において、
前記蛍光体が、前記投影レンズの湾曲する像面よりも小さな曲率を有し、かつ前記像面と同一方向に湾曲する湾曲体として形成され、かつ蛍光体の左右中央位置が、前記投影レンズの湾曲する像面の左右中央位置近傍に配置されたことを特徴とする車両用前照灯。
