Description
図1は、実施形態1に係る車両用灯具の概略構造を示す鉛直断面図である。図2は、実施形態1に係る車両用灯具の内部構造を模式的に示す斜視図である。本実施形態に係る車両用灯具1は、車両前方の左右に配置される一対の前照灯ユニットを有する車両用前照灯装置である。一対の前照灯ユニットは左右対称の構造を有する点以外は実質的に同一の構成であるため、図1には車両用灯具1として一方の前照灯ユニットの構造を示す。
実施形態2に係る車両用灯具は、2つの光源と、当該2つの光源のそれぞれに対応する光学部材とを備える点を除き、実施形態1に係る車両用灯具1の構成と概ね共通する。実施形態1と同様の構成については同一の符号を付し、その説明及び図示は適宜省略する。図7は、実施形態2に係る車両用灯具の内部構造を模式的に示す鉛直断面図である。図8は、実施形態2に係る車両用灯具の内部構造を模式的に示す斜視図である。図9(A)、図9(B)、図10(A)及び図10(B)は、実施形態2に係る車両用灯具が形成する配光パターンの一例を示す模式図である。
実施形態3に係る車両用灯具は、配光パターン形成部が液晶シャッタである点を除き、実施形態1又は2に係る車両用灯具1の構成と概ね共通する。実施形態1又は2と同様の構成については同一の符号を付し、その説明及び図示は適宜省略する。図11(A)は、実施形態3に係る車両用灯具の内部構造を模式的に示す鉛直断面図である。図11(B)は、実施形態3に係る車両用灯具の内部構造を模式的に示す斜視図である。
