A white light emitting device, a light bar and a light apparatus. A relative spectrum of the white light emitting device is ϕ(λ). A relative spectrum of a black body radiation with a corresponding color temperature is S(λ). An area normalization is performed on ϕ(λ) and S(λ) to convert an equal energy spectrum ϕ′(λ) of the white light emitting device and an equal energy spectrum S′(λ) of the black body radiation with the corresponding color temperature. A degree of similarity R of the equal energy spectrum of the white light emitting device and the equal energy spectrum of the black body radiation satisfies the following formula: when λi is 380 nm, λn is 680 nm, R≥85%.
