Abstract

A fluorescent bulb-type electronic energy-saving lamp includes a screwshell and an electronic ballast sealed within the screwshell so that the lamp has the same shape and size as standard incandescent lamps thereby allowing the fluorescent bulb-type electronic energy-saving lamp to directly replace standard incandescent bulbs. The fluorescent bulb-type electronic energy-saving lamp also includes a fluorescent tube, a bulb cover surrounding the fluorescent tube and a connector for mounting the screwshell, the fluorescent tube and the bulb cover thereon.
