The invention provides a lamp panel manufacturing method. The lamp panel manufacturing method is characterized by comprising the steps that a plane plate 9 is manufactured through equipment accordingto a design scheme; according to the design scheme, the plane plate 9 is divided into a quadrilateral substrate area 1B, quadrilateral side wall areas 2B arranged on the four sides of the substrate, first platform areas 3B arranged at the positions, on the four sides of the substrate, one sides of the side wall areas 2B, vertical edge area 4B arranged on one sides of the first platform areas 3B, and second platform areas arranged in the vertical edge areas 4B; prefabricated holes 101 are formed in the four corners of the substrate area 1B of the plane board 9 through equipment, and mounting holes 51 are formed in the two sides of each second platform area 5B through the equipment; the second platform areas 5B, the vertical edge areas 4B, the first platform areas 3B and the side wall areas2B are subjected to the 90-degree bending process to form second platforms 5, vertical edges 4, first platforms 3 and side walls 2; after the bending procedure is completed on the plane plate, the second platforms 5 are located under a substrate 1 and over the first platforms 3, and the prefabricated holes 101 are correspondingly located over the mounting holes 51. The method is suitable for automatic production, high in efficiency and environmentally friendly.
