WHITE LIGHT SOURCE, LIGHT BAR, AND LAMP

WIPO Patent Application WO/2020/220690

A1

A white light source, a light bar, and a lamp. The relative spectral power distribution of the white light source is Ф(λ). When λ is in a wavelength range of 420-660 nm, the symmetric spectrum peaks are respectively P1, P2 and P3, and the corresponding characteristics are as follows: regarding P1, the peak wavelength is 600-660 nm and the peak width at half height is 90-140 nm; regarding P2, the peak wavelength is 500-550 nm and the peak width at half height is 60-110 nm; regarding P3, the peak wavelength is 420-480 nm and the peak width at half height is 30-80 nm. The white light source can emit a spectrum having a small fluctuation amplitude and excellent continuity and the spectrum is closer to sunlight, and thus, a good illumination effect can be provided to a user, so that the user can obtain a feeling similar to that outdoors during indoor activity. The white light source can be mounted on a base plate to further form the light bar that can emit light similar to sunlight. The white light source and the light bar can be applied to the lamp.
