Abstract

This paper presents a light-emitting diode (LED) driver for general lighting applications. In addition to providing a high stable current source for the LED biasing, the new circuit provides an energy-efficient way for light intensity control using a pulse width modulation (PWM)-based dimming circuit. Moreover, we introduce a feedback thermal control circuit to ensure the LED being operated at a temperature lower than 60 °C so as to minimize the light intensity degradation and to prolong the lifetime of the LED lamps.
