Abstract
A front-mounted high-voltage LED light source for supplementing light to plants includes a substrate, a high-voltage LED chip set, a first layer of glue powder and a second layer of glue powder. By controlling a weight ratio of the transparent adhesive medium and the red fluorescent particles in the first layer of glue powder, as well as thickness of the first layer of glue powder; and, by controlling a weight ratio of the transparent adhesive medium and the yellow fluorescent particles in the second layer of glue powder, as well as the thickness of the second layer of glue powder, a ratio range of photon number of red light, blue light to green light emitted by the front-mounted high-voltage LED light source for supplementing light to plants per a unit time is (65-95):(5-30):(5-25).
