To enable the accurate formation of a light distribution pattern for road surface drawing, etc. in a vehicular lighting having a lighting unit including a spatial light modulator and a projection lens and stored in a lighting chamber.SOLUTION: A configuration is provided such that light from a light source 52 reflected at a spatial light modulator 30 is emitted toward the front of a lighting via a projection lens 72, which permits the accurate formation of various light distribution patterns for road surface drawing. In addition, a configuration is provided such that an adjustment mechanism 90 is included as a lighting unit 10 which adjusts the relative positional relation in an anterior-posterior direction of the lighting between a bracket 40 for supporting the spatial light modulator 30 and a lens holder 74 for supporting the projection lens 72, and the adjustment mechanism 90 is provided in a manner to be operable from an outside of a lighting chamber. Consequently, even upon the occurrence of slight shift of the focal point of a projection optical system as a vehicular lighting 100 including even a translucent cover 104 in the anterior-posterior direction of the lighting from the original position, adjustment to the original position can be made through operation of the adjustment mechanism 90.SELECTED DRAWING: Figure 3

    【課題】空間光変調器および投影レンズを備えた灯具ユニットが灯室内に収容された車両用灯具において、路面描画用配光パターン等を精度良く形成可能とする。【解決手段】空間光変調器30で反射した光源52からの光を、投影レンズ72を介して灯具前方へ向けて照射する構成とすることにより、種々の路面描画用配光パターンを精度良く形成可能とする。その上で、灯具ユニット10として、空間光変調器30を支持するブラケット40と投影レンズ72を支持するレンズホルダ74との灯具前後方向の相対的な位置関係を調整するための調整機構90を備えた構成とし、この調整機構90を灯室外から操作可能な態様で設ける。これにより、透光カバー104をも含めた車両用灯具100としての投影光学系の焦点が本来の位置から灯具前後方向に微妙にズレてしまっても、調整機構90の操作により本来の位置に合わせることができるようにする。【選択図】図3
