    • A light emitting device having a high light emitting efficiency is provided. The light emitting device is provided with a light-emitting chip 4 which emits a first light having a peak wavelength within a first wavelength range; a fluorescent layer 6, which is arranged above the light-emitting chip 4 and emits a second light having a peak wavelength within a second wavelength range which is larger than the first wavelength range, corresponding to the first light; and a reflecting surface which surrounds a region between the light-emitting chip 4 and the fluorescent layer 6 and scatters and reflects the first light emitted from the light-emitting chip 4 and the first light reflected by the fluorescent layer 6.
    • 提供了具有高发光效率的发光器件。 发光装置设置有发射具有第一波长范围内的峰值波长的第一光的发光芯片4; 布置在发光芯片4上方的荧光层6,发射对应于第一光的第二波长范围内的峰值波长的第二光,该第二波长范围大于第一波长范围; 以及包围发光芯片4和荧光层6之间的区域的反射面,并且散射并反射从发光芯片4发射的第一光和由荧光层6反射的第一光。
