LED street lamp with charging pile

Abstract

The invention discloses an LED street lamp with a charging pile. The LED street lamp comprises a correcting circuit, a filter circuit, a PWM switch circuit and a charging loop, wherein the correcting circuit is used for conducting correction on current distortion in a driving circuit and the compensation of power factors to improve the quality of electric energy; the filter circuit is used for eliminating the influence of higher harmonics and clutters on the driving circuit; the PWM switch circuit is used for driving the LED street lamp to work by controlling the conduction time of a switch tube to realize the real-time dimming function of the LED street lamp; the charging loop is arranged between the filter circuit and the PWM switch circuit and is used for charging electric vehicles, wherein the charging loop, the correcting circuit and the PWM switch circuit are simultaneously matched and controlled by the same control module so as to complete the charging process of the vehicles cooperatively on the basis of the dimming of the LED street lamp. The LED street lamp is integrated with double functions of lighting and electric vehicle charging, and has a high application value.

Description

technical field [0001] The invention relates to a street lamp, in particular to an LED street lamp with a charging pile. Background technique [0002] Existing street lamps are often controlled by alternating current timing and constant voltage drive mode, which is easy to control. However, the current research hotspot is to use LED as the lighting source of street lamps, which has better lighting effects, high energy efficiency, environmental protection, and longer service life. [0003] However, the disadvantage of this control method is that it is impossible to adjust the output light intensity of the LED lamp in real time according to the brightness and darkness of the external connection. It can only be turned on and off at regular intervals, and the given driving voltage is constant. The alternating current turns into direct current, and then the filtering device is directly used to shape the waveform, and finally the shaped direct current is used to drive the lighting...
