Street lights involve lighting technology and are suitable for street lights. The purpose is to design a high-efficiency electronic energy-saving street lamp with long life, low power consumption, high power factor and low current harmonic content. The high-efficiency electronic energy-saving street lamp includes the power grid high-voltage discharge branch R1, C1, rectifier bridge D1-D4, power factor correction branch C2, D5, D6, high and intermediate frequency glitch filter branch L1, L3, and high-frequency oscillation circuit connected in sequence BG1-BG2, start branch L2, C7 and lamp tube T; compared with previous street lamps, it can save 80% of electricity; harmonic content THD<25%, extending lamp life up to 3-4 times.
