The lighting industry’s benchmark for the end of service life is defined as when LED output drops to 70% of its initial ...

This study proposes a novel light-emitting diode (LED) driver circuit that stabilizes the lighting output without a photodiode. The LED driver circuit is composed of a self-alignment circuit to ...

This paper presents a novel methodology to regulate the output current in CCM/DCM-operated buck converters to be used as post-regulators in LED lamp drivers. With this novel method only the current of ...
