A sunlight type photosynthetic light-conversion glass plane light source consists of a hollow glass assembly (1) and luminescent material films (2) thereof. Two pieces of glass use super-white patterned glass industrial product. A rare earth luminescent material film (2) with the thickness of 10 microns to 80 microns is deposited on a patterned surface (4) of one of the two pieces of glass. Red light with the characteristic wavelength of 660 nanometers is generated under irradiation of blue light and green light. The light source can prevent deliquescence and deterioration of a light conversion material, can be easily recycled, is uniform in light irradiation and high in mechanical strength, and can be easily produced by using large-scale industrial production.
