Title:
LIGHT-EMITTING SYSTEM FOR HEALTHY LIGHTING, LIGHT BAR AND LAMP
Document Type and Number:
WIPO Patent Application WO/2020/220689
Kind Code:
A1
Abstract:
Provided are a light-emitting system for healthy lighting, a light bar and a lamp, wherein same are applied to the field of lighting and can emit white light with a color temperature range from 2700 K to 6500 K. A relative spectral power of the light-emitting system is set to be Ф(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. Limiting the first characteristic waveband, the second characteristic waveband and the third characteristic waveband achieves the output of white light, and also reduces spectra that are harmful to a human body, and increases spectra that are beneficial to the human body, thereby achieving healthy lighting.
