Abstract
© 2019 IEEE.This paper proposes a strategy for controlling an energy-saving lamp for rural application. The proposed energy saving lamp adopts the LED lighting technology to improve the energy saving target. The luminous efficacy of the LED lamp is regulated by controlling the LED operation point in its exponential voltage-current relationship using amplitude modulation mechanism. A direct feedback and a direct feed forward are adopted to improve the conventional PI controller performance for tracking the ramp reference signal. Simulation results showed that the proposed mechanism can track the lamp operating scenario very well.
