Abstract

resumo “circuito de acionamento de led usando conversor de retorno para reduzir de cintilação optica observável através da redução de redes de ondulação ac retificados” o presente pedido descreve um circuito de acionamento para o fornecimento de uma corrente de comando a um regime de iluminação led. em particular, a presente invenção refere - se a um circuito controlador de entrada ac, operável em conjunto com um dispositivo regulador de corrente que utiliza uma pluralidade de díodos de zener conectados em combinações paralelas. o circuito de acionamento compreende um mecanismo de realimentação que pode ser operado para manter uma tensão constante ao longo do regulador de corrente. formas de realização da presente invenção procuram resolver a ondulação led e, deste modo, a cintilação óptica proveniente de um acionamento de led, ligado na sua entrada, a um fornecimento de corrente alternada.
