Abstract
【解決手段】ベース基板1と、ベース基板1上に配設されるLED素子21及びLED素子21に覆設される多角形状の蛍光体22からなる発光体2と、透光性の樹脂からドーム状に形成され、発光体2に覆設されて2発光体から放射される光を拡散させるドーム部材3と、ドーム部材3を介して放射される発光体2の光の配光制御を行うレンズ4とを備え、前記発光体2は、ベース基板1上に略同心円状に複数配設され、少なくとも1つの発光体2が、他の発光体2とは配設方向が異なる。
【選択図】図1
Description
また、入射側面531bよりレンズ53内に入射した光は、レンズ53内において全反射を繰り返して出射面53bより出射し、略円形の照射面を形成する。
本実施形態の照明器具について図1、2を用いて説明を行う。
LED素子21は、例えば、InGaN系の材料からなり青色光を発する青色LED素子が用いられ、ベース基板1表面に形成される凹部1aの底面に実装される。
