Abstract:
1. A light emitting device, comprising a light emitting component based on a nitride compound semiconductor and a phosphor capable of absorbing a part of the light emitted by the light emitting component and emitting light of a wavelength different from that of the absorbed light, wherein a white color light is obtained by mixing a blue light emitted by the light emitting component and the light generated by the phosphor, the chromaticity point (x, y) of the light generated by the phosphor satisfies 0.45≦x≦0.49 and 0.51≦y≦0.53, and a peak wavelength of the blue light from the light emitting component is from 420 nm to 490 nm.
