Problems solved by technology

The LED blue light used in common plant lighting (Horticultural Lighting) is a narrow-wave blue light of 450nm. Although this wavelength is the intersection wavelength of chlorophyll a, chlorophyll b and carotenoids, this wavelength is not the most effective wavelength for photosynthesis. reduce the efficiency of photosynthesis

Abstract

The embodiment of the invention discloses a light source for plant illumination. The light source for plant illumination comprises a substrate, a plurality of blue light chips with different emission spectrums which are arranged on the substrate, and a packaging body arranged on the substrate and covering the plurality of blue light chips. A synthetic spectrum of the plurality of blue light chips has a plurality of crest points in a wavelength range of 400 nm-540 nm, the normalized intensity of each of the plurality of crest points is greater than 60%, and the full width at half maximum of the synthetic spectrum is in a range of 25 nm-80 nm. The full width at half maximum of the synthetic spectrum of the light source for plant illumination can be as wide as possible in a blue light wave band below 500 nm, so that the full width at half maximum is close to that of a plant illumination model, and the requirements of different blue light wavelengths of various plants are met.

Description

technical field [0001] The invention relates to the technical field of light sources, in particular to a light source for plant lighting. Background technique [0002] Plant growth requires several important elements. In addition to temperature, moisture, air and minerals, light is also an extremely important element. Plant photosynthesis requires red light and blue-violet light, because the pigments on plant chloroplasts are mainly chlorophyll and carotenoids, of which chlorophyll absorbs red light and blue-violet light, while carotenoids only absorb blue-violet light, so plants Red and blue-violet light are most needed for photosynthesis. From figure 1 According to the plant absorption spectrum shown, the absorption wavelengths of chlorophyll a (Chla), chlorophyll b (Chlb) and carotenoids (Caro) are all different. The LED blue light used in common plant lighting (Horticultural Lighting) is a narrow-wave blue light of 450nm. Although this wavelength is the intersection w...
