Abstract
According to the photon grating diffraction principle, the extraction efficiency of LED with photonic crystal can be improved. In this paper, the dielectric photonic crystal is introduced into the SiO2 layer of the red LED to improve the extraction efficiency. The theoretical analyses and experimental results show that the LED with dielectric photonic crystal can well achieve the extraction efficiency. The luminous flux of new type LED is improved by 26% compared with the normal red LED.
