To provide a device which can draw a multicolor image of a complex shape onto an object clearly and easily by use of an inexpensive optical component.SOLUTION: A drawing device 11 for vehicle comprises three lamp units 51, 52, 53 inside a lamp casing 12. Each lamp unit 51, 52, 53 includes: a light source 27 which generates visible light; a condenser lens 28 which condenses light from the light source 27; a shade 38 which forms outgoing light of the condenser lens 28 to an image of a required shape; and a projection lens 48 which projects the formed image to the front of a lamp. At least one of the light source 27, the condenser lens 28, and the projection lens 48 generates colored light. At least two lamp units overlap images, which are respectively colored to colors different from each other, at a same position in the front of the lamp, and draw colored images onto a road surface.SELECTED DRAWING: Figure 5
【課題】安価な光学部品を用いて、複雑な形状の多色画像を対象物に鮮明かつ簡易に描画できる装置を提供する。【解決手段】車両用の描画装置11は、ランプケーシング12の内側に3つのランプユニット51,52,53を備える。各ランプユニット51,52,53は、可視光を発生する光源27と、光源27からの光を集める集光レンズ28と、集光レンズ28の出射光を所要形状の画像に形成するシェード38と、形成された画像をランプ前方へ投射する投影レンズ48とを含む。光源27、集光レンズ28、投影レンズ48の少なくとも一つが着色光を生成する。少なくとも2つのランプユニットは、それぞれ異なる色に着色された画像をランプ前方の同じ位置で重ね合わせ、路面に着色画像を描画する。【選択図】図5
