PROBLEM TO BE SOLVED: To form a variety of light distribution patterns without giving a glare to drivers of a vehicle on the opposite lane and an own vehicle by using both a high-brightness light source and a low-brightness light source.SOLUTION: A head light for a vehicle comprises an ADB controller 21 for controlling an orientation pattern of a high beam while being adapted to a driving condition. The ADB controller 21 is provided with: a driving information input part 22 for inputting driving information from various sensors thereto; a driving condition determination part 23 for determining a current driving condition on the basis of the input information; an orientation control part 24 for controlling actuators 8, 9 for swivel and leveling; a low beam light source 10; a light source control part 25 for controlling light output of a low-brightness light source 11 and a high-brightness light source 13; and a CPU 26 for controlling the orientation control part 24 and the light source control part 25 in association with each other on the basis of a determination result of the driving condition.SELECTED DRAWING: Figure 3
【課題】高輝度光源と低輝度光源を併用し、対向車や自車両の運転者に眩しさを与えることなく、多様な配光パターンを形成する。【解決手段】車両用前照灯は、運転状況に適応させてハイビームの配向パターンを制御するためのADB制御装置21を備える。ADB制御装置21には、各種センサー類から運転情報を入力する運転情報入力部22と、入力情報に基づいて現在の運転状況を判別する運転状況判別部23と、スイブル用およびレベリング用のアクチュエータ8,9を制御する配向制御部24と、ロービーム光源10、低輝度光源11および高輝度光源13の光出力を制御する光源制御部25と、運転状況の判別結果に基づいて配向制御部24と光源制御部25を関連付けて制御するCPU26とが設けられている。【選択図】図3
