Zusammenfassung: | To correspond to both of a light distribution pattern requiring a shade such for a low beam light distribution and the like and a light distribution pattern that does not need a shade for a high beam light distribution and the like, with one lens unit.SOLUTION: A lens unit is equipped with a microlens array (MLA) that has a plurality of optical systems, and a shade mechanism. The shade mechanism has a plurality of light shielding members, and a drive portion 72. The light shielding members are provided in a space formed between an incident side lens and an emission side lens, and blocks at least a part of light from the incident side lens toward the emission side lens. The drive portion 72 can switch the positions of the plurality of light shielding members between a first position where at least a part of light is blocked, and a second position where at least a part of light is not blocked.SELECTED DRAWING: Figure 3
【課題】一つのレンズユニットで、ロービーム用配光等のシェードを必要とする配光パターンと、ハイビーム用配光等のシェードが不要な配光パターンの両方に対応可能にする。【解決手段】レンズユニットは、複数の光学系を有するマイクロレンズアレイ(MLA)と、シェード機構と、を備える。シェード機構は、複数の遮光部材と、駆動部72と、を有する。遮光部材は、入射側レンズと出射側レンズとの間に形成された空間に設けられ、入射側レンズから出射側レンズへ向かう少なくとも一部の光を遮る。駆動部72は、複数の遮光部材の位置を、少なくとも一部の光を遮る第1位置と少なくとも一部の光を遮らない第2位置とに切り替え可能である。【選択図】図3 |
