Abstract

CIRCUITO ADAPTATIVO PARA ACIONAR UMA CARGA CC DE BAIXA TENSÃO A PARTIR DE UMA ALIMENTAÇÃO CA DE ALTA TENSÃO RETIFICADA, LÂMPADA DE RETROAJUSTE DE LED E MÉTODO DE ACIONAMENTO DE UMA CARGA CC DE BAIXA TENSÃO A PARTIR DE UMA ALIMENTAÇÃO CA DE ALTA TENSÃO RETI-FICADA A invenção descreve um circuito adaptativo (1, 1') para acionar uma carga CC de baixa tensão (2) de uma alimentação CA de alta tensão retificada (3), cujo circuito adaptativo (1, 1') compreende um circuito de armazenamento de carga (21, 21' ), cujo circuito de armazenamento de carga (21, 21') compreende um primeiro capacitor (C1) e um segun-do capacitor (C2) conectados essencialmente em série, em que o segundo capacitor (C2) é conectado pelo menos em paralelo com a carga (2); e um interruptor ativo (22, 22') implementado como uma fonte de corrente controlada (22, 22') para controlar uma corrente de carga (Icarga) através da carga (2) de modo que, em um estado fechado do interruptor, a corrente de carga (Icarga) seja atraída essencialmente do primeiro capaci-tor (C1) do circuito de armazenamento de carga (21, 21' ), e, durante um estado aberto do interruptor, a corrente de carga (Icarga) seja atraída do segundo capacitor (C2). A in-venção também descreve uma lâmpada de retroajuste de LED (4) que compreende um meio de conexão (40) para conectar a lâmpada (4) a um sinal de alimentação da rede elétrica de tensão mais alta (UPS); um dispositivo de LED (2) classificado para uma ten-são de alimentação mais baixa; e tal circuito adaptativo (1, 1') para adaptar o sinal de alimentação da rede elétrica de tensão mais alta (UPS) em um sinal de tensão baixa (UC2) para acionar o dispositivo de LED de tensão mais baixa (2). A invenção também descreve um método de acionamento de uma carga CC de baixa tensão (2) a partir de uma alimentação CA de alta tensão retificada (3).
