摘　　要：为了研究大型LED方形阵列照度均匀度的变化规律,利用大型LED方形阵列照度分布的对称性,建立了大型LED方形阵列照度均匀度的理论模型,得出大型LED方形阵列照度均匀度的公式以及计算方法。利用这些公式和计算方法研究并得出了大型LED方形阵列照度均匀度的变化规律。这些公式和计算方法较之前的公式和计算方法更加简捷和便于数值计算,为研究大型LED方形阵列的照度均匀性提供了理论依据,也为大型LED方形阵列的照度均匀性设计提供了简便方法,弥补了之前对大型LED阵列照度均匀性研究理论和研究方法上的不足。In order to study the regularity of uniformity of illumination of large LED square array,using the symmetry of large LED square array illumination distribution,a theoretical model for the illumination uniformity of large LED square arrays is established. The formula and calculation method of the uniformity of large LED square array are obtained. The regularity of uniform uniformity of large LED square arrays is obtained by using these formulas and calculating methods. These formulas and calculations are simpler and easier to compute than before,and they provide a theoretical basis for studying the uniformity of large LED square array,and they also provides a simple method for uniform design of large LED square array. It makes up for the lack of the uniformity of LED array illumination.
