Energy-saving electronic lamp

The utility model relates to an integral energy saving lamp which is formed by the way that an electronic ballast and a tube type fluorescent tube are connected. The electronic ballast comprises a high frequency pi-shaped LC filter circuit, a bridge rectifying circuit, a capacitor filtering circuit, a capacitor diode filtering circuit, a high frequency oscillation and power amplification circuit, a fluorescent lamp circuit and a protection circuit, wherein the capacitor diode filtering circuit is additionally provided with a high frequency filtering capacitor on the structure basis of two capacitors and three diodes. A diode and an inductor are respectively connected in series between a positive connecting line and a negative connecting line of a capacitor filter and a capacitor diode filter. A freewheeling circuit of the inductor is arranged. The power factor is more than 0.98, the total amount of the harmonic wave is less than 13 percent, and the wave peak ratio is less than 1.5.
