Fabrication method for lamp hood

The invention provides a fabrication method for a lamp hood and belongs to the technical field of lighting lamps. The fabrication method comprises the steps of plate material heating, plastic suckingmolding, waste material edge cutting, bending and bonding. According to the fabrication method for the lamp hood provided by the invention, firstly, overall heating is performed on a first optical diffusion plate, and an upper cover is obtained utilizing plastic sucking molding and edge cutting operations; then a bending area of a second optical diffusion plate is heated to a heat deflection temperature, and a back hood is obtained through a bending process; the upper cover and the back hood are fixed through the bonding, and the lamp hood is finally obtained; and because the back hood is fabricated by adopting the bending process, the separate arrangement of a plastic sucking mold is not needed, furthermore, no waste materials are generated, the material utilization rate is increased, andthe production cost is sa
