摘要	When a 300 m300 m chip is divided into 33 small chips with 20 m adjacent spacing, the total saturated output power enhances up to 5.19 times and the maximum inject current increases 7 times nearly. The consequences indicate LED chip with smaller pixels array can possess greater inject current and higher saturated output power than the primary chip. Meanwhile, the effects of chips number and LED chips distance for irradiance distribution on target plane illuminated by multi-LED chips are studied. The irradiance uniformity reaches its peaks when LED chip-to-chip distance equals to maximum flat condition dmax. In addition, the irradiance uniformity area is increasing when the number of LED chips increasing. When the target plane is illumined by nine 300 m300 m LED chips with distance dmaxand each chip is divided into nine 80 m80 m smaller pixels, the irradiance value is 3 times as primary LED chips array while the uniformity of irradiance not changing. 2016, Science Press.
