PROBLEM TO BE SOLVED: To provide a lighting appliance for a vehicle which is improved in a degree of freedom related to a direction and a range of radiated light, and can be used as a drawing lamp unit for displaying a figure, a mark and a character.SOLUTION: A lamp unit 2 comprises: a light source 7 for emitting light; a rotating reflector 8 which rotates with a rotating shaft A as a pivot, and has a plurality of reflection faces 8a, 8b, 8c, 8d, 8e and 8f for reflecting the light which is emitted from the light source; and a fixed reflector 9 to which the light reflected by a plurality of the reflection faces is made incident, and which controls the incident light. Angles with respect to rotating axes of a plurality of the reflection faces are different from one another, an incident position of the light which is made incident to the fixed reflector is changed according to a rotation position of the rotating reflector, and in a state that the light-on/off of the light source is controlled according to the rotation position of the rotating reflector, a figure, a mark and a character are drawn by a plurality of pieces of spot light which are obtained by rotating the rotation reflector.SELECTED DRAWING: Figure 15
【課題】 照射される光の方向及び範囲に関する自由度の向上を図ると共に、図形や記号や文字が表示される描画用の灯具ユニットとして用いることができるようにする。【解決手段】 灯具ユニット2は、光を出射する光源7と、回転軸Aを支点として回転され光源から出射された光を反射する複数の反射面8a、8b、8c、8d、8e、8fを有する回転リフレクタ8と、複数の反射面で反射された光が入射され入射された光を制御する固定リフレクタ9とを備え、複数の反射面の回転軸に対する角度がそれぞれ異なり固定リフレクタに入射される光の入射位置が回転リフレクタの回転位置に応じて変化され、光源の点消灯が回転リフレクタの回転位置に応じて制御された状態において、回転リフレクタを回転して得られる複数の点状の光によって、図形や記号や文字を描くようにされた。【選択図】図15
