Abstract

DISPOSITIVO DE ILUMINAÇÃO QUE PERMITE A VARIAÇÃO DE INTENSIDADE DO LED Um dispositivo de iluminação (1) compreende: - terminais de entrada da alimentação (2, 3); - uma fonte de energia (30), possuindo terminais de entrada (31, 32) acoplados aos terminais de entrada da alimentação e possuindo três terminais de saída (33, 35, 34), um dos ditos terminais de saída sendo um terminal comum de saída (35). Uma primeira saída (36) é definida por um primeiro terminal de saída e pelo dito terminal comum de saída; uma segunda saída (37) é definida por um segundo terminal de saída e pelo dito terminal comum de saída. Uma primeira sequência de LED (110) é conectada a primeira saída de fonte de energia em série com um primeiro resistor (120). Uma segunda sequência de LED (210) é conectada à segunda saída de fonte de energia em série com um segundo resistor (220). A fonte de energia é controlável para variar a tensão no terminal comum de saída dentro do intervalo da tensão no primeiro terminal de saída à tensão no segundo terminal de saída.
