Abstract
Un circuito de controlador LED ilustrativo incluye una función de control de encendido y apagado automático que utiliza un circuito de detección de luz que tiene un elemento de detección de luz que reacciona a la luz ambiental. El circuito utiliza topología de convertidor flyback y un controlador PFC. La función de detección de luz se proporciona al acoplar el circuito de detección de luz a una función de monitoreo/desactivación del controlador PFC, proporcionando de esa forma control de encendido y apagado automático del circuito del controlador LED al utilizar un elemento de detección de luz tal como una fotocelda.
