Abstract
A light-emitting system for healthy lighting, a light bar and a light fixture, wherein they are applied to the field of lighting and can emit white light with a color temperature range of 2700 K to 6500 K. A relative spectral power of the light-emitting system is set to be ϕ (λ), and a relative spectral power distribution of a solar spectral curve corresponding to the color temperature is set to be S (λ). The white light has a first characteristic waveband, and a wavelength region of the first characteristic waveband is 380-405 nm. The white light has a second characteristic waveband, and a wavelength region of the second characteristic waveband is 415-455 nm. The white light has a third characteristic waveband, and a wavelength region of the third characteristic waveband is 465-495 nm.
