To provide a device which can draw a multiple image onto a road surface or a wall surface 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, and overlaps plural images, which are projected from the projection lens 48, at a same position, and draws a multiple image onto a road surface. The LED light source 27, the condenser lens 28, the shade 38, and the projection lens 48 are located at a same position on optical axes 51A, 52A, 53A of the lamp units.SELECTED DRAWING: Figure 5
【課題】安価な光学部品を用いて路面や壁面に多重画像を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とを含み、投影レンズ48から投射された複数の画像を同じ位置で重ね合わせて路面上に多重画像を描画する。LED光源27、集光レンズ28、シェード38、投影レンズ48をランプユニットの光軸51A,52A,53A上の同じ位置に配設する。【選択図】図5
