Wide utilization of Light Emitting Diodes (LEDs) is one of the most promising tendencies of modern lighting technologies. Implementation of LEDs ensures high efficacy of luminaries, lower power losses and, when equipped with dimmable power supplies, provides also improved functionality of the luminaries that, in turn, in principle reduces amount of energy spent for lighting purposes. However, operation of the LED luminaries depends a lot on the current regulation method implemented in the dimmer. This paper analyzes the impact of pulse modulation methods implemented with MSP430 microcontroller on the losses of the dimmer and luminary and on their efficiency.
