Description
図1は、実施形態1に係る車両用灯具の概略構造を示す正面図である。図2は、実施形態1に係る車両用灯具の概略構造を示す鉛直断面図である。図2は、図1における基準鉛直線V1に沿った概略断面図に相当する。なお、図1では、エクステンション12、ブラケット102の走査部保持部102c及び蛍光部材搭載部102dの図示を省略している。また、図1の基準鉛直線V1及び基準水平線H1は、図3の鉛直ラインV及び水平ラインHにそれぞれ対応する。
灯具ユニット100は、ブラケット102、レーザ光源104、走査部106、第1蛍光部材108、第2蛍光部材110、第3蛍光部材112、第1リフレクタ114、第2リフレクタ116、投影レンズ118等を有する。
制御ユニット400は、各種演算処理を実行するCPU、各種制御プログラムを格納するROM、データ格納やプログラム実行のためのワークエリアとして利用されるRAM等(全て図示せず)で構成される。制御ユニット400は、走査部106の走査用アクチュエータを制御して、紫外レーザ光UVを各蛍光部材に分配する。また、制御ユニット400は、レーザ光源104の照射強度を制御する。本実施形態において、制御ユニット400は、光学部材ごとに、入射される紫外レーザ光UVの照射強度を制御する。この照射制御には、紫外レーザ光UVの照射強度をゼロにすること、及びゼロから所定照射強度まで増大させること、すなわちレーザ光源104を点消灯することも含まれる。
実施形態2に係る車両用灯具1は、導光部材を備え、レーザ光源及び操作部が灯室外に配置される点が、実施形態1に係る車両用灯具1の構成との主な相違点である。実施形態1と同一の構成については同一の符号を付し、その説明および図示は適宜省略する。
実施形態3に係る車両用灯具1は、リアコンビネーションランプである点が実施形態2に係る車両用灯具1の構成との主な相違点である。実施形態2と同一の構成については同一の符号を付し、その説明および図示は適宜省略する。
