Light emitting device

The embodiment of the invention provides a light emitting device. The light-emitting device comprises a first light-emitting unit, the range of the color coordinate x of the first light-emitting unit is 0.6 > x > 0.53, and the color point of the first light-emitting unit is near a black body radiation ray; the range of the color coordinate x of the second light-emitting unit is 0.48 > x > 0.4, and the color point of the second light-emitting unit is above the black body radiation ray; the range of the color coordinate x of the third light-emitting unit is 0.24 > x > 0.18, and the color point of the third light-emitting unit is above the black body radiation ray; moreover, the area enclosed by the color points of the first light-emitting unit, the second light-emitting unit and the third light-emitting unit covers the area with the color temperature range of 1800K-10000K on the black body radiation ray, large-range color temperature dimming can be realized, and CIExy is enabled to be attached to the black body
