Abstract
【解決手段】照明器具1は、LED2からの光を導入し、その光を導いて外部に出射する導光板3を備える。導光板3は、光を導入する導入部31と、その導入された光を導光方向D1に伝播させつつ、外部に導出する導出部32を有する。導入部31は、LED2が対向配置される入射面31aと、入射面31aを覆うように形成され、入射面31aによる入射光を反射して導出部32に向かわせる反射面31bを有する。導出部32は反射面31bと連なる光出射面32aを有し、光出射面32aは反射面31bと連なる領域に光拡散面32bを有する。LED2から導光板3に入射した光のうち、反射面31bで反射されることなく反射面31bと連なる光出射面32aの領域に直接到達した光が、その領域に在る光拡散面32bにより拡散されるので、導出部32の輝度むら及びグレアを抑制することができる。
