To provide a vehicular lighting fixture capable of compatibly having a light distribution pattern for headlamp of high luminosity that the law requests and a pattern for road surface drawing of high resolution (an image of complicated characters, a figure, etc.).SOLUTION: A vehicular lighting fixture comprises: a screen member where a first image is formed through irradiation with light scanned in two dimensions and having a first spot diameter, and a second image is formed through irradiation with light scanned in two dimensions and having a second spot diameter smaller than the first spot diameter; and a projection optical system which projects the images formed on the screen member to form a light distribution pattern corresponding to the images.SELECTED DRAWING: Figure 1
【課題】法規が求める高光度のヘッドランプ用配光パターン及び解像度の高い路面描画用パターン(複雑な文字や図形等の画像)を両立させることができる車両用灯具を提供する。【解決手段】二次元的に走査される第1スポット径の光が照射されることで第1画像が形成され、かつ、二次元的に走査される前記第1スポット径より小さい第2スポット径の光が照射されることで第2画像が形成されるスクリーン部材と、前記スクリーン部材に形成された画像を投影して当該画像に対応する配光パターンを形成する投影光学系と、を備える車両用灯具。【選択図】 図1
