Paper Title:
White LED Energy-Efficient Drive Technology Based on Luminescent Relaxation Properties
  Abstract

This study is a high-performance, energy-saving drive technology for all pcLED based on luminescence relaxation properties. Its core idea is coordination between power driving model and pcLED relaxation properties. Compared with relative small pulse width, forward pulse excitation current can make pcLED luminescence tends to its saturation peak rapidly during this period because of the steep leading edge of relaxation properties. And in the vacant period of forward pulse excitation current, because of the chosen of best duty cycle, it will be the most effective utilization for luminescence afterglow which has slow attenuation characteristic.
