SEMICONDUCTOR LIGHT-EMITTING DEVICE
First Claim
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;
a first light transmissible layer which covers the semiconductor light-emitting element and contacting with the plane surface of the substrate;
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 projections reflecting shapes of the phosphor particles; and
a second light transmissible layer which covers the phosphor layer and contacting with the plane surface of the substrate.

Abstract
A light-emitting device is provided, which includes 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, a first light transmissible layer formed above the substrate and covering the semiconductor light-emitting element, a phosphor layer formed above the first light transmissible layer and containing phosphor particles and matrix, and a second light transmissible layer formed above the phosphor layer and contacting with the plane surface of the substrate. The surface of the phosphor layer has projections reflecting shapes of the phosphor particles.
