Abstract

resumo sistema de driver para led, lâmpada e método de acionamento de um led em um sistema um sistema de driver para led (1) compreende uma fonte de corrente (4) que fornece uma corrente de fornecimento de energia (i) a um conjunto paralelo do comutador paralelo (20) e a um led (10). o comutador paralelo (20) causa curto-circuito no led (10) quando está fechado. um controlador (15) gera, durante o uso: (i) um primeiro sinal de controle (e) para controlar a fonte de corrente (4) para mudar de um modo de regulação, em que a corrente de fornecimento de energia (i) é regulada para apresentar um nível médio diferente de zero, para um modo de decadência, em que a corrente de fornecimento de energia (i) decai durante um período de decadência (td), e (ii) segundo sinal de controle (cso) para controlar o comutador paralelo (20) para ser aberto durante um período de abertura (to) compreendendo um sub-período do período de decadência (td). 1/1
