发光装置
摘要：
本发明提供一种能够实现具有高发光效率的白色光源的发光装置。其具有：封装部(1)，具有搭载半导体发光元件的第1部分和其周围的第2部分；半导体发光元件(3)，被搭载在所述封装部的所述第1部分上，发出在近紫外区域具有发光峰值的光；透明树脂层(5)，覆盖所述半导体发光元件被设置在所述封装部的所述第1部分及所述第2部分上，在相对于所述第1部分和第2部分垂直的剖面上的外周为向上凸的曲线状；和层叠体，包括设置在所述透明树脂层之上具有到达所述第2部分的端面、并依次形成为向上凸的曲线状的红色荧光体层(6)、黄色荧光体层(7)、绿色荧光体层(8)和蓝色荧光体层(9)，所述黄色荧光体层，顶部的厚度比所述端面的厚度厚。
摘要（英）：

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.
