【課題】車両用灯具に用いた場合などに光の利用効率を低下させることなく遠方視認性を改善することができるレーザ光源装置を提供する。 【解決手段】 レーザ光源装置１は、レーザ出射口からレーザ光を発するレーザ光源１０と、レーザ光源１０のレーザ出射方向前方に設けられてレーザ光を集光する集光レンズ２０と、集光レンズ２０のレーザ出射方向前方に設けられて集光レンズ２０によって集光されたレーザ光を受光してレーザ光の波長とは異なる波長の光を発する蛍光体部（波長変換部）４０と、レーザ光源から集光レンズに至るレーザ光の光路を形成する導光部３０と、を含む。導光部３０は、レーザ出射口の外側にレーザ光の光軸に沿って延在している端面３１を有し、導光部の端面３１は、導光部３０内を伝搬する光を全反射によって反射させる反射面を形成している。 【選択図】図２

車両用灯具

【課題】光軸方向寸法が短いレーザー光源装置を用いた車両用灯具を提供する。 【解決手段】レーザー光源装置と、所定配光パターンを形成するように構成された光学系を備えた車両用灯具において、レーザー光源装置は、光透過性部材からなる円柱形状であって、レーザー光を内部に導入する入光面を含む一端面、外周面及び他端面を含む表面を備え、表面のうち入光面以外の領域に散乱面が設定された導光部と、導光部の円柱軸を含む第１平面と導光部の円柱軸を含みかつ第１平面に対して所定角度傾斜した第２平面とで囲まれた出光領域上に配置された蛍光体と、表面のうち入光面及び出光領域以外の領域上に配置された反射膜と、入光面から導光部内部に導入され、散乱面で散乱し、出光領域から散乱光として出射し、蛍光体に入射するレーザー光を出射するレーザー光源を備えており、導光部とレーザー光源とが隣接して配置されている。 【選択図】図１０

車載システム

【課題】グレアを低減しつつ歩行者等をより良好に撮影する車載システムを提供する。【解決手段】自車両の周辺空間を撮影する車載カメラ、周辺空間に対して光を照射する車両用灯具、車両用灯具の点灯状態を制御する制御装置を含む。車載カメラは、露光時間と非露光時間を有する単位露光サイクルを繰り返して露光時間に周辺空間を撮影する。制御装置は、車両用灯具により、露光時間と非露光時間の各々で複数のパルス光を照射されるように車両用灯具の点灯状態を制御する。露光時間における複数のパルス光の光度の平均的な大きさが相対的に高く、非露光時間における複数のパルス光の光度の平均的な大きさが相対的に低く設定されている。【選択図】図４
