More Information
Summary:The utility model relates to a self-ballast and compact type fluorescent tube for lighting. In an existing lamp body, an energy-saving fluorescent lamp tube is electrically connected with a high-frequency electronic ballast; the high-frequency electronic ballast is electrically connected with a metallic lamp holder on the lamp body through a conducting wire; a group of passive harmonic suppression circuits are added in the electronic energy-saving lamp; the passive harmonic suppression circuits are respectively connected to the AC input end and the DC output end of a bridge rectifier circuit in the high-frequency electronic ballast. After urban electricity is conducted on the lamp holder, the energy-saving fluorescent lamp tube can be immediately lightened and glow; the light efficiency is high; the power factor can reach more than 0.9.
