The invention relates to a glass fiber reinforced plastic lighting fixture shell, belonging to the technical field of outdoor lighting fixture processing. According to the processing technology disclosed by the invention, organic glass fiber reinforced plastic substitutes for aluminium, aluminium alloy or magnesium alloy material, wherein the organic glass fiber reinforced plastic comprises the following raw material components: unsaturated polyester resin, polyester gel coat resin, roving checked cloth, a chopped fiber felt, a surface mat, a curing agent, an accelerating agent, a demoulding agent and a thin film. The processing technology of the glass fiber reinforced plastic lighting fixture shell comprises the following steps of: automatically inspecting a construction site, carrying out pre-treatment on a mould, selecting a reinforcing material, cutting the reinforcing material, selecting a polyester resin glue solution, preparing the polyester resin glue solution, carrying out gel coat construction, pasting, solidifying, and carrying out product inspection, thus the glass fiber reinforced plastic lighting fixture shell is obtained. The glass fiber reinforced plastic lighting fixture shell product disclosed by the invention has the advantages of corrosion resistance, flame retardance, light weight, high strength, ageing resistance, strong designability, safety, skid resistance, excellent electrical property, no magnetic property and safety in use in anti-electromagnetic anti-knock environment.
