発光装置および照明装置

Abstract

【課題】発光むらを低減させて、発光輝度の向上を図ること。 【解決手段】基体2と、基体2上に搭載された発光素子4と、発光素子4から放射された光を上方へ導く光反射面と、第1の透光性部材5と、蛍光体層7とを備えている。第1の透光性部材5は、平坦な上面を有しており、発光素子を被覆している。蛍光体層7は、透光性材料および蛍光体からなり、第1の透光性部材5に対して隙間をあけて配置されている。 【選択図】図1
<P>PROBLEM TO BE SOLVED: To improve luminance by reducing light emitting unevenness. <P>SOLUTION: The light emitting device includes a substrate 2, a light emitting element 4 mounted on the substrate 2, a light reflection plane for guiding light radiated by the light emitting element 4 upward, a first translucent member 5, and a phosphor layer 7. The first translucent member 5 has a flat upper surface, and covers the light emitting element. The phosphor layer 7 is composed of a translucent material and a phosphor, and arranged with a gap with respect to the first translucent member 5. <P>COPYRIGHT: (C)2007,JPO&INPIT
