光学ユニット

【課題】簡易な構成で複数の配光パターンを形成可能な新たな光学ユニットを提供する。【解決手段】光学ユニット１８は、複数の発光素子がアレイ状に配置されている第１の光源２０と、第１の光源２０から出射した光を反射しながら回転する回転リフレクタ２２と、複数の発光素子の点灯状態を制御する制御部２９と、を備える。回転リフレクタ２２は、回転しながら反射した光を光源像として走査することで配光パターンを形成するように反射面が設けられており、複数の発光素子は、第１の発光素子および第２の発光素子を含む。制御部２９は、第１の発光素子の点灯時間Ｔ１が、第２の発光素子の点灯時間Ｔ２（Ｔ２＞０）よりも長くなるように、第１の発光素子および第２の発光素子の点灯状態を制御する。【選択図】図１

車両用灯具

【課題】車両用灯具において、部品点数を低減する。 【解決手段】車両用灯具１００は、ＬＥＤ３７と、ＬＥＤ３７を載置するためのＬＥＤ搭載部２７と、ＬＥＤ３７をＬＥＤ搭載部２７に固定するためのアタッチメント４４と、ＬＥＤ３７に給電するための給電部と、ＬＥＤ３７から出射された光を反射するリフレクタ４９と、リフレクタ４９からの光を灯具前方に投影する投影レンズ３０とを備える。給電部と、リフレクタ４９とは、アタッチメント４４に設けられている。 【選択図】図２

車両用灯具

【課題】ロービーム用配光パターンのカットオフラインから上方の領域を含むとともに複数の個別パターンに分割された付加配光パターンを形成可能な車両用灯具における消費電力の低減を図るための技術を提供する。 【解決手段】車両用灯具１は、ロービーム用配光パターンのカットオフラインから上方の領域を含むとともに複数の個別パターンに分割された付加配光パターンを形成可能な車両用灯具であって、複数の個別パターンの一部を形成するための灯具ユニット２０Ｌと、少なくとも灯具ユニット２０Ｌで形成しない個別パターンを含む複数の個別パターンの他の一部を形成するための灯具ユニット２０Ｒとを備え、各灯具ユニットで形成された個別パターンが合成されて付加配光パターンが形成される。 【選択図】図１

Vehicle headlight

A vehicle headlight ( 10 ) includes a light source unit ( 30 ) including a plurality of light emitting elements ( 35 ), a reflector ( 39 ) that scans light from the plurality of light emitting elements ( 35 ) to form a light distribution pattern ( 350 ), and a control unit ( 60 ). The control unit ( 60 ) controls the light source unit ( 30 ) such that the light amount of light emitted from some light emitting elements to a predetermined region (AR) overlapping a target object does not change and the light amount of light emitted from other some light emitting elements to the predetermined region (AR) overlapping the target object changes among the light emitting elements that emit light to the predetermined region (AR) overlapping the target object in the superimposition region (PA).
