Over the last years, GaN-based light-emitting diodes (LEDs) have been shown to be excellent candidates for the realization of high-efficiency light sources. White LEDs based on phosphor conversion can reach record efficiencies in excess of 150 lm W −1 , as demonstrated by several manufacturers and r...
