Abstract
【解決手段】灯具ユニット(5)は、前面(12f)と後面(12b)とで正の屈折力を有する第1のレンズ(12)と、第1のレンズ(12)の後ろに配置され、正の屈折力を有する正屈折領域(14u,14d)を有する第2のレンズ(14)と、正屈折領域(14u,14d)の後側焦点(A,B)近傍に配置された光源(16,18)と、を有するので、光源(16,18)を離間して配置することができる。
【選択図】図2
Description
図1は第1の実施形態に係る灯具1の正面図、図2は第1の実施形態に係る灯具1の縦断面図(図1のII−II線に沿う断面図)である。
本発明に係る灯具ユニット5は、後方の第2のレンズ14の正屈折領域の数に応じてより複数の配光を形成することができるので、この形態について説明する。図7は第2の実施形態に係る灯具1の縦断面図である。なお、第1の実施形態と同様の構成については同一の符号を付して説明を省略する。
さらに、第1のレンズ12および第2のレンズ14は、以下の変形を伴ってよい。図9は本発明の実施に係るレンズの変形例である。第1の実施形態を元に説明する。同一の構成については、同一の符号を付して説明を省略する。
