LED chip-containing photonic crystal side direction light extractor

An LED chip-containing photonic crystal side direction light extractor comprises a substrate, an n-pole area, an active layer and a p-pole area, wherein, an N electrode is arranged on the n-pole area; a P electrode and a current-diffusing layer are arranged on the p-pole area; and a protective layer is arranged on the current-diffusing layer. The chip is characterized in that: the photonic crystal side direction light extractor comprises a column array; the column arrays penetrate the p-pole area, the active layer and the n-pole area to the surface of the substrate; the photonic crystal side direction light extractor comprises the column array which is arranged on the circumference of the chip and a column array which is arranged in the middle of the chip; and the current-diffusing layer between the N electrode and the P electrode keeps an electric conduction pathway. As the photonic crystal side direction light extractor is arranged to revise the light angle, the chip further has the advantage that more lateral optical is project to the outside, thereby greatly improving the external quantum efficiency of an LED, overcoming the problems that the light taking efficiency of a chip is low; the stress is centralized; the calorific value is big; and the radiating effect is poor. Therefore, the produced LED has the advantages that the performance is stabler; and the luminance is even larger.
