Abstract:
1. A light-emitting device comprising: a substrate having a plane surface; a semiconductor light-emitting element mounted on the plane surface of the substrate and which emits light in a range from ultraviolet ray to visible light; laminated structure which covers the semiconductor light-emitting element and contacts the plane surface of the substrate, the structure having a radius R a first light transmissible layer; a phosphor layer which covers the first light transmissible layer, the phosphor layer contacting with the plane surface of the substrate and containing phosphor particles and matrix, a surface of the phosphor layer having unevenness reflecting shapes of the phosphor particles, the phosphor particles having a diameter ranging from 45 μm to 70 μm; and a second light transmissible layer which covers the phosphor layer and contacting with the plane surface of the substrate, wherein the phosphor particles are contained in the phosphor layer at a concentration of 20 wt % or more.
