Abstract
This article analyzes the efficacy of the light sources and their limitations in theory and in technology. The LED's spectra were simulated by a Gaussian model to calculate the efficacy. The conventional light sources have been compared with LEDs; the results show that significant increase of LEDs' internal quantum efficiency and extraction efficiency is essential for LED application in general lighting.
