Abstract
resumo patente de invenção: "ativação de led para pisca-pisca corrente". a presente invenção refere-se a uma cadeia de diodos emissores de luz com uma pluralidade de diodos emissores de luz (led1 ... led4) alimentados por uma fonte de corrente, ligados em série, sendo que a cada diodo emissor de luz está associado um circuito de ativação (5), que apresenta um comutador (q), que apresenta um circuito em série ligado em paralelo ao diodo emissor de luz de uma queda de tensão de referência (d1) da tensão (uref), e de um comutador (q) controlado e que é preparado para comparar a tensão de controle (ust) medida contra uma base do circuito em série de led com a tensão na ligação do comutador com o led seguinte da cadeia ou a base e fechar ou abrir o comutador, caso a tensão de controle (ust) caia aquém de um valor predeterminado ou aumente além de um valor predeterminado.
