PURPOSE: A photosynthesis promoting composition for LED is provided to improve the photosynthesis efficiency of green plants or photosynthetic cells, thereby improving yield, and the productivity of single cell protein. CONSTITUTION: A photosynthesis promoting composition for LED comprises 60-98 weight% of heat-resistant transparent resin, 2-40 weight% of phosphors for wavelength band conversion. The mixing weight ratio of the phosphors for wavelength band conversion is 1:0.05 - 0.35, a relative spectral powder, which is the main absorption zone of chlorophyll a at 430-440nm and 645-670mm is respectively 0.6-1.0 and 0.3-0.8. The phosphors for wavelength band conversion additionally comprises green phosphors, and the mixing weight ratio of the yellow phosphors, red phosphors, and green phosphors is 1:0.05-0.35:0.1-0.20. |
