发明名称 LIGHT EMITTING DEVICE AND LIGHTING APPARATUS
摘要 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.
