Abstract
(EN)
A light shining device (130) comprises a light source (32), and a rotatable mirror (134) that reflects light emitted from the light source (32). The rotation of the mirror (134) displaces the reflection direction of the light emitted from the light source (42), whereby the light is split into a plurality of levels, is scanned in a line shape, and forms a light distribution pattern. The mirror (134) is structured from at least one reflective surface (134a), and is structured such that the curvature in the rotation direction of the mirror (134) changes at the at least one reflective surface (134a).
(FR)
L’invention concerne un dispositif de projection de lumière (130) qui comprend une source de lumière (32), et un miroir (134) rotatif qui réfléchit la lumière émise par la source de lumière (32). La rotation du miroir (134) déplace la direction de réflexion de la lumière émise par la source de lumière (42), la lumière étant divisée en une pluralité de niveaux, étant balayée en une forme de ligne, et formant un motif de distribution de lumière. Le miroir (134) est structuré à partir d’au moins une surface réfléchissante (134a), et est structuré de sorte que la courbure dans la direction de rotation du miroir (134) change à hauteur de la surface ou des surfaces réfléchissantes (134a).
(JA)
光照射装置(130)は、光源(32)と、光源(32)から出射された光を反射させる回転可能なミラー(134)と、を備えている。ミラー(134)の回転によって光源(42)から出射された光の反射方向が変位することで、光が複数の段に分かれてライン状に走査されて配光パターンを形成する。ミラー(134)は、少なくとも一つの反射面(134a)から構成され、少なくとも一つの反射面(134a)においてミラー(134)の回転方向における曲率が変化するように構成されている。
