Abstract

The invention discloses an LED drive circuit, and belongs to the field of integrated circuits. The LED drive circuit comprises a voltage division module, a capacitor charging inhibition module, a first capacitor, a ripple current filtering module and an LED module. The voltage division module is used for dividing the voltage output by the rectification module. The voltage division module is electrically connected with the capacitor charging inhibition module. The first capacitor and the capacitor charging inhibition module are connected in series between the rectification module and the ground, and the LED module and the ripple current filtering module are connected in series and then are connected in parallel with the first capacitor, thereby realizing high power factor of the driving circuit, no stroboflash compatibility when the LED module is lightened, and constant current flowing through the LED.

Description

technical field [0001] The application belongs to the field of integrated circuits, and in particular relates to an LED driving circuit. Background technique [0002] With the development of lighting technology, LED lights have entered thousands of households. Before lighting the LED lamp, it is necessary to use a driving circuit to drive and light the LED lamp. [0003] In the prior art, LED lamps are generally driven by a multi-stage linear drive circuit. In the specific driving process, the multi-segment linear drive circuit conducts in segments according to the input voltage level, and the current input to the multi-segment linear drive circuit approximates a sinusoidal waveform, and the power factor value is high; however, due to the segmental conduction with the input voltage level, the current The current flowing through the LED is related to the frequency of the input voltage, which will cause the current flowing through the LED light to contain power frequency rip...
