To make it possible to form a clear drawing light-distribution pattern after enhancing efficiency in utilization of light emitted from a light emitting device with inexpensive arrangement in a drawing lighting fixture constituted so as to form the drawing light-distribution pattern.SOLUTION: Between a light emitting device 20 and a projection lens 30, an image generating member 40 for generating an image serving as an origin of a drawing light-distribution pattern is disposed. In this case, the image generating member 40 is constituted of a translucent member, and then a part of a light emitting surface 42a is constituted as a translucent region 42aA, and surroundings thereof is constituted as a light shielding region 42aB with a plurality of corner cubes 50 formed thereon. Thus, while the translucent region 42aA generates the image serving as the origin of the drawing light-distribution pattern, light which reaches the light shielding region 42aB is retro-reflected by the plurality of corner cubes 50 toward the side of a light incident surface 42b of the image generating member 40, thereby being prevented from being emitted to a space in front of a lighting fixture.SELECTED DRAWING: Figure 2

    【課題】描画用配光パターンを形成するように構成された描画用灯具において、安価な構成によって発光素子からの出射光の利用効率を高めるようにした上で、鮮明な描画用配光パターンを形成可能とする。【解決手段】発光素子20と投影レンズ30との間に、描画用配光パターンの元となる画像を生成するための画像生成部材40を配置する。その際、画像生成部材40を透光部材で構成した上で、その出射面42aの一部を透光領域42aAとして構成し、その周囲を複数のコーナーキューブ50が形成された遮光領域42aBとして構成する。これにより、透光領域42aAによって描画用配光パターンの元となる画像を生成する一方、遮光領域42aBに到達した光については複数のコーナーキューブ50によって画像生成部材40の入射面42b側へ向かって再帰反射させ、灯具前方側の空間へ出射させないようにする。【選択図】図2
