The manufacturing process is simplified by making it possible to easily form a circular reflector plate for preventing heat dissipation and improving heat dissipation effect and lighting efficiency, and a donut plate-shaped metal frame plate for supporting a light-transmitting cover from a single circular thin metal plate. The aim is to reduce costs by reducing waste and eliminating waste in material collection.

無駄がなく、低コスト化が図れるという効果がある。As described above, in the present invention, the upper base plate is formed by bending a cap-shaped bottomed cylindrical part in the center of the circular thin metal plate by embossed molding process, and punching out this cap-shaped upper base plate. Since the metal frame button and the circular reflector are formed at the same time, the process for forming the circular reflector is also used as the process for forming the metal frame, so the process for forming the circular reflector is especially necessary. This has the advantage of simplifying the manufacturing process, and since the part that would normally be discarded as punching waste is used as a circular reflector, there is no waste in material collection, and the cost is low. This has the effect of making it possible to
