To improve visibility of an operator.SOLUTION: A vehicle head lamp 100 comprises a control part 40 which determines based on a detection result of an object detection part 30 whether or not an overlapping light distribution pattern, which is overlapped on a preceding vehicle, is exists in plural unit light distribution patters P1, P2,..., P8. The control part determines whether or not a set value of the overlapping light distribution pattern P2, P3, P4 exceeds a permissible value Y which is set based on a relative positional relationship with respect to the preceding vehicle when it is determined that the overlapping light distribution pattern exists, determines whether or not irradiation of the overlapping light distribution pattern is possible in the state that the set value of the overlapping light distribution pattern is so decreased as to be the permissible value or less when it is determined that the set value exceeds the permissible value Y, irradiation of the overlapping light distribution pattern is performed in the state that the set value of the overlapping light distribution pattern is so decreased as to be the permissible value or less and to a value closest to the permissible value in a settable range when it is determined that the irradiation is possible, and turns off the overlapping light distribution pattern when it is determined that the irradiation is not possible.SELECTED DRAWING: Figure 1

    【課題】運転者の視認性を向上させる。【解決手段】車両用前照灯100は、対象物検出部30の検出結果に基づいて、複数の単位配光パターンP1、P2、…、P8において先行車に重複する重複配光パターンが存在するか否かを判定し、重複配光パターンが存在すると判定した場合に、重複配光パターンP2、P3、P4の設定値が先行車について相対位置関係に基づいて設定される許容値Yを超えるか否かを判定し、許容値Yを超えると判定した場合、重複配光パターンの設定値を許容値以下の値に減少させた状態で重複配光パターンを照射することが可能か否かを判定し、照射可能であると判定した場合に重複配光パターンの設定値を許容値以下の値であって設定可能な範囲で最も許容値に近い値に減少させた状態で重複配光パターンを照射させ、照射可能ではないと判定した場合に重複配光パターンを消灯させる制御部40とを備える。【選択図】図1
