Description
色した後の混合光を拡散させる方法が考えられる。例えば、照明装置の開口部等に拡散透過パネルや拡散透過フィルム等の拡散透過部材を配置することで、レーザ光と波長変換光との混合光を拡散させる方法が考えられる。
実施の形態に係る照明装置1の構成について、図1を用いて説明する。図1は、実施の形態に係る照明装置1の構成を示す図である。なお、図1において、光源50以外は、断面を示している。
たレーザ光LB4は、光拡散構造40で拡散反射して拡散光LD5(図6の一点鎖線)となって光拡散構造40から等方散乱的に放射される。
以上、本発明に係る照明装置について、実施の形態に基づいて説明したが、本発明は、上記実施の形態に限定されるものではない。
