摘要
通过分析多颗LED组成的各种阵列在近场平面上的照度分布,来设计可实现近场照度均匀的LED排列方式和距离。基于LED的光强分布,构建单颗LED的光强分布模型(并非朗伯分布),给出了方程和等式用于计算不同排列方式下的LED分布距离和封装密度,以实现近场平面上的照度均匀。
The multiple LEDs illumination arrangement and distance for uniform near-field illumination are designed hy ana lyzing near-field plane intensity distribution of kinds of LED arrays in the paper. The intensity distribution model of a single LED （an imperfect Lambertian distribution） is established based on a LED intensity distribution. The different approximate equations and formulas for calculating the packaging density and the distance among multiple LEDs are also given in order to achieve the uniform near-field illumination.
