Abstract
resumo circuito de retificação de corrente alternada e método de retificação de corrente alternada para a condução de um módulo led são revelados um circuito de retificação de corrente alternada e um método de retificação de corrente alternada para a condução de um módulo de led. o método compreende: quando um módulo de corrente alternada está no meio ciclo positivo, depois de uma corrente alternada é retificado, a saída de corrente alternada para um meio ciclo positivo de retificação do circuito de derivação de um módulo de led; quando o módulo de corrente alternada é um meio ciclo negativo, a realização de carregamento de acordo com a saída de corrente alternada pelo módulo de corrente alternada, e quando o módulo de corrente alternada está no meio ciclo positivo, a realização de descarga, e a saída de corrente alternada para um semi-ciclo circuito de alimentação ramo positivo do módulo de led; quando o módulo de corrente alternada está no meio ciclo negativo, retifica a corrente alternada, e a saída de corrente alternada para um semi-ciclo negativo retificação do circuito de derivação do módulo de led; quando o módulo de corrente alternada está no meio ciclo positivo, a realização de carregamento de acordo com a saída de corrente alternada pelo módulo de corrente alternada, e quando o módulo de corrente alternada está no meio ciclo negativo, a realização de descarga, e a saída de corrente alternada para um semi-ciclo circuito de alimentação ramo negativo do módulo de led; e quando uma voltagem de um sinal de tensão de entrada for superior a um limiar de tensão pré-definido, que desliga um circuito de proteção de sobretensão ramo do módulo de leds. ao utilizar o presente invento, a estabilidade de uma tensão de saída pode ser melhorada, e a eficiência luminosa do led pode ser melhorada.summary AC rectification circuit and AC rectification method for conducting a led module An alternating current rectification circuit and an AC rectification method for conducting a led module are disclosed. The method comprises: when an alternating current module is in the positive half cycle, after an alternating current is rectified, the alternating current output for a positive half cycle rectification of the branch circuit of a led module; when the alternating current module is a negative half cycle, charging according to the alternating current output by the alternating current module, and when the alternating current module is in the positive half cycle, discharging, and ac output for a half-cycle positive branch power circuit of the led module; when the AC module is in the negative half cycle, rectifies the alternating current, and the AC output for a negative half cycle rectification of the led module branch circuit; when the alternating current module is in the positive half cycle, charging according to the alternating current output by the alternating current module, and when the alternating current module is in the negative half cycle, discharging, and ac output for a half-cycle negative branch power supply of the led module; and when a voltage of an input voltage signal exceeds a predefined voltage threshold, which shuts off an overvoltage protection circuit from the LED module. By using the present invention, the stability of an output voltage can be improved, and the luminous efficiency of the led can be improved.
