摘要

摘要: 基于几何光学与辐射照度理论，对菱形、环形和蜂窝状等3种典型LED阵列光源在近场上的照度分布进行研究，推导了不同阵列光源照射到目标面上的总辐射照度表达式，并依据斯派罗法则确定了LED间的最优化距离。进而根据照度公式，对LED阵列进行了仿真和对比分析，得出了不同阵列的光照度分布特点。菱形阵列可以得到较大范围的平坦度，环形阵列的平坦范围较小，能量集中分布在一个圆形范围内，有良好的集光效果，蜂窝状阵列的照度比较集中且占用的面板空间较小，可在一定程度上降低设计成本。

Abstract: Based on geometrical optics and irradiance theory, the illumination distributions of the rhombus, circular ring and honeycomb LED arrays under uniform near field lighting were analyzed. Formulae for calculating total irradiance to target surface of different array light sources were deduced. According to Sparrow's criterion, the optimal distance between LED arrays was determined. Moreover,based on the illumination formulae presented in this paper, three LED arrays were simulated and comparatively analyzed, and the different illuminance distribution characteristics of the LED arrays were received. The rhombus array can obtain a wide range of flatness; The flat range of circular ring array is small, and the energy is concentrated in a circular range, which can collect the light effectively; The flat range of honeycomb array is small and the light occupies small panel space, which can reduce the design costs to a certain extent.
