Abstract

detecção e controle de suprimento de energia led. a presente invenção refere-se a um circuito que detecta o tipo de suprimento de energia acionando um led pela análise de um sinal recebido do suprimento de energia. o circuito controla um comportamento do led, tal como sua reação a um redutor ou condições térmicas, com base no tipo determinado. outra modalidade reduz o led com base em um ciclo de tarefa detectado em um sinal de energia de entrada. um circuito de gerenciamento térmico detecta uma temperatura od led, obtém uma faixa operacional térmica do led, e gera um sinal de controle sem resposta.
