Zusammenfassung:To provide a lighting fixture for vehicles that has optical axis adjusting function and yet achieves light weight and low cost through a reduction in the number of components and also allows the simplification of an assembly process.SOLUTION: A vehicular headlight 1 uses a plurality of light sources to make individually a light distribution pattern. At least one of light sources respectively included in a plurality of light distribution modules comprises a set of multiple light emitters, which is a light-emitter set light source 50 capable of brightness control on a minimum light emission unit. A light distribution controller 10 connected to the light-emitter set light source 50 has a light emission distribution area setting unit 100 having a light emission distribution area 50a to be set in a light emission range of the light-emitter set light source 50. When adjusting misalignment between a low beam light distribution pattern LP and a high beam light distribution pattern HP, the light emission distribution area setting unit 100 performs misregistration correction to move the light emission distribution area 50a on the basis of information on misalignment of both light distribution patterns LP and HP from a designed position in a state where the light distribution modules 4 and 5 have been assembled.SELECTED DRAWING: Figure 4 【課題】光軸調整機能を備えながら、部品点数の削減による軽量化・低コスト化と組立工程の簡素化が可能な車両用灯具を提供すること。【解決手段】車両用前照灯1は、複数の光源を用いて個別に配光パターンを生成する。複数の配光モジュールのそれぞれに有する光源のうち少なくとも一つの光源は、多数の発光素子の集合体により構成され、最小発光単位での輝度制御が可能な発光素子集合光源50としている。発光素子集合光源50に接続された配光コントローラ10は、発光素子集合光源50の発光範囲内に発光分布領域50aを設定する発光分布領域設定部100を有している。発光分布領域設定部100は、ロービーム配光パターンLPとハイビーム配光パターンHPの位置ずれを調整する際、配光モジュール4,5を組付けた状態にて両配光パターンLP,HPの設計位置からの位置ずれ情報に基づき、発光分布領域50aを移動させる位置ずれ補正を行う。【選択図】図4
