Claims (3)
- 光源と、
該光源からの光束を前方へ反射する第1の反射部と、
前記第1の反射部を相互に直角の2軸の各軸回りに並行して揺動させ前記第1の反射部からの反射光束の進行方向を変化させるアクチュエータと、
前記第1の反射部からの反射光束のうち、下側進路範囲の反射光束を、上側進路範囲の反射光束の照射先の方へ反射する第2の反射部とを備え、
前記第1の反射部の前記2軸の各軸回りの揺動範囲のうち上下方向の揺動範囲の上側折り返し時の前記第1の反射部からの反射光束の進行方向と、前記上下方向の揺動範囲の下側の折り返し時の前記第2の反射部からの反射光束の進行方向が照射領域のカットラインに向けられていることを特徴とする車両用前照灯。 - 請求項1の車両用前照灯において、前記第2の反射部は、前記第1の反射部から下向きに反射されて来る反射光束ほど、反射後の向きが上向きになるように、位置及び向きが設定されていることを特徴とする車両用前照灯。
- 請求項2記載の車両用前照灯において、
前記2軸は、前記第1の反射部からの反射光束を左右方向へ振らせる揺動を前記第1の反射部が行う際の揺動軸としての第1の軸と、前記第1の反射部からの反射光束を上下方向へ振らせる揺動を前記第1の反射部が行う際の揺動軸としての第2の軸とであり、
前記アクチュエータは、前記第2の軸回りの前記第1の反射部の振動周波数が前記第1の軸回りの前記第1の反射部の振動周波数より大となるように、第1の反射部を前記第1及び第2の軸回りに並行して揺動させることを特徴とする車両用前照灯。
