LIGHT-EMITTING DEVICE
First Claim
1. A light-emitting device comprising:
- a package having, on a surface thereof, a first portion and a second portion surrounding the first portion;
a semiconductor light-emitting element mounted on the first portion and emitting a light having an emission peak at a near-ultraviolet region;
a transparent resin layer covering the semiconductor light-emitting element and contacted with the first portion and the second portion, the transparent resin layer having an arch-like outer profile, as seen in a cross section when cut perpendicularly to the surface; and
a laminated body formed on the transparent resin layer with end faces of the laminated body being contacted with the second portion, the laminated body having an arch-like outer profile, as seen in a cross section when cut perpendicularly to the surface and comprising a red fluorescent layer, a yellow fluorescent layer, a green fluorescent layer and a blue fluorescent layer which are laminated in the mentioned order, the yellow fluorescent layer having a top portion larger in thickness than that of the end face portions thereof.

Abstract
A light-emitting device is provided, which includes a package having a first portion and a second portion surrounding it, a semiconductor light-emitting element mounted on the first portion and emitting a light having an emission peak in a near-ultraviolet region, a transparent resin layer covering the semiconductor light-emitting element and contacted with the package, and a laminated body formed on the transparent resin layer with end faces of the laminated body being contacted with the second portion. The transparent resin layer has an arch-like outer profile perpendicular cross section. The laminated body has an arch-like outer profile in perpendicular cross section and comprises a red fluorescent layer, a yellow fluorescent layer, a green fluorescent layer and a blue fluorescent layer laminated in the mentioned order. The yellow fluorescent layer has a top portion which is made larger in thickness than that of the end face portions thereof.
