| description | PROBLEM TO BE SOLVED: To provide a technique that can form an irradiated region and an unirradiated region separated in a direction intersecting with a scanning direction in a light distribution pattern formed by an optical unit.SOLUTION: An optical unit 40 comprises a rotating reflector 42 that rotates about a rotating axis R in one direction while reflecting light emitted from a light source. The rotating reflector 42 is provided with a plurality of reflecting surfaces 42a and 42b so that the light from the light source reflected during rotation forms a desired light distribution pattern. The reflecting surfaces comprise the first reflecting surface 42a that forms a first partial region R1 of the light distribution pattern, and the second reflecting surface 42b that forms a second partial region R2 of the light distribution pattern different from the first partial region R1.SELECTED DRAWING: Figure 7
【課題】光学ユニットが形成する配光パターンにおいて、走査方向と交差する方向に分割された照射領域と非照射領域とを形成可能な技術を提供する。【解決手段】光学ユニット４０は、光源から出射した光を反射しながら回転軸Ｒを中心に一方向に回転する回転リフレクタ４２を備える。回転リフレクタ４２は、回転しながら反射した光源の光が所望の配光パターンを形成するように複数の反射面４２ａ，４２ｂが設けられており、反射面は、配光パターンの第１の部分領域Ｒ１を形成する第１の反射面４２ａと、第１の部分領域Ｒ１と異なる、配光パターンの第２の部分領域Ｒ２を形成する第２の反射面４２ｂと、有する。【選択図】図７ |
