PURPOSE:To simplify the wiring and to make the fabrication process automatical by building a metallic plate in a mounting base for supporting a curved tube type fluorescent lamp and stabilizer and connecting parts on it to form operational circuits. CONSTITUTION:A chassis 2 of synthetic resin having a cap 9 on its end and a mounting base 5 formed flat on the other end is surrounded with a base 3, a saddle-shaped curved tube type fluorescent lamp 19 and stabilizer 16 are mounted on the base 5, these are surrounded with a globe, and a fluorescent lamp which is interchangeable with an incandescent lamp is formed. When a metallic plate 32 with a specific shape is built in the base 5 through the entire surface, and the lamp 19, stabilizer 16, and a capacitor 31 are connected on a current terminal which is exposed from the surface of the base 5. Thus operational circuits can be formed very easily, and the radiation efficiency can be improved due to the metallic plate 22. |
