PROBLEM TO BE SOLVED: To generate a light distribution pattern in which a center part of an irradiation region becomes bright and an end part becomes dark in a head lamp for generating scanning light by an optical deflector.SOLUTION: First and second optical deflectors 12a, 12b emit first and second scanning light Lb1, Lb2 so that a horizontal direction scanning range Q1 of the first scanning light Lb1 and a horizontal direction scanning range Q2 of the second scanning light Lb2 become a left side and a right side in an irradiation region and also, come into contact with each other. A light source control unit 6 lights a first light source 11a only in a period in which the first scanning light Lb1 is emitted to the irradiation region, and it lights a second light source 11b only in a period in which the second scanning light Lb2 is emitted to the irradiation region.

    【課題】光偏向器により走査光を生成するヘッドランプにおいて、照射領域の中心部が明るく、端部が暗くなる配光パターンを生成する。【解決手段】第1及び第2光偏向器12a,12bは、第1走査光Lb1の水平方向走査範囲Q1と第2走査光Lb2の水平方向走査範囲Q2とが、照射領域において左側及び右側となり、かつ相互に接するように、第1及び第2走査光Lb1,Lb2を出射する。光源制御部6は、第1走査光Lb1が照射領域に出射される期間のみ、第1光源11aを点灯し、第2走査光Lb2が照射領域に出射される期間のみ、第2光源11bを点灯する。【選択図】図5
