Abstract

Se proporciona un circuito para proporcionar la compensación térmica para un circuito de activación utilizado para activar diodos emisores de luz (LED). El circuito de activación puede incluir un circuito rectificador configurado para rectificar la fuente de energía AC en una fuente de energía DC que proporciona un voltaje de fuente DC. El circuito de activación también puede incluir un circuito transformador configurado para transformar el voltaje de fuente DC para proporcionar un voltaje de activación para activar los diodos emisores de luz. El circuito transformador puede incluir un elemento de conmutación que es controlado con base por lo menos en parte de un circuito de detección de corriente que tiene un transistor de detección. Un transistor de rastreo térmico es provisto como parte de la referencia del circuito de detección.
