Title:
LIGHTING FIXTURE USED FOR MICROALGAE CULTIVATION AND MANUFACTURING METHOD FOR SAID LIGHTING FIXTURE
Document Type and Number:
WIPO Patent Application WO/2020/191738
Kind Code:
A1
Abstract:
Provided in the present invention are a lighting fixture used for microalgae cultivation and a manufacturing method for said lighting fixture, the lighting fixture comprising: a lighting fixture assembly and at least one LED lamp bead mounted on the lighting fixture assembly, the lighting fixture at least having the following light emission features: a) a spectrum with a wavelength of 500 nm-660 nm being partially or completely formed by the excitation and conversion of fluorescent materials; b) the peak wavelength of the spectrum being 400 nm-500 nm, and the half-wave width of the spectrum being less than 50 nm; c) the spectrum having a second peak between 500 nm-660 nm, and the absolute difference between the peak and valley of the relative spectrum being less than 0.25; and d) in the spectrum of the lighting fixture, the ratio of the radiant energy of red light to blue light and the ratio of the radiant energy of red light to green light being between 0.5-1. The spectral curve and the microalgae absorption spectral curve of the lighting fixture of the present invention coincide, the light energy utilisation efficiency is high, and the absorption of different microalgae can be satisfied.
