The invention provides a production method of a luminescent material. The production method comprises the following steps: selecting raw materials, wherein the raw materials comprise modified grapheme, barium sulfate, aluminum oxide, nano-titanium dioxide, nano-zinc oxide, vinyl silicone oil, fluorite and epoxy resin; making the luminescent material, then uniformly spraying the surface of a lamp shell of an LED lamp and curing for 1 hour at a temperature of 50 DEG C. Compared with the prior art, the production method provided by the invention has the following beneficial effects that the diffuse reflection effect of a glass lamp shade is significantly enhanced, the light transmittance performance is enhanced, the irradiation range of the lamp is expanded, and the glare effect is effectively reduced; therefore, the lighting effect is better.
