摘　　要：面状LED发光体灯珠的分布和分组问题,可建模为多约束优化问题来进行求解。提出了一种将面状LED发光体灯珠照度映射为质心容量限制Power图的容量,从而布局LED灯珠的方法,实现了面状LED发光体照度均匀的目标,进一步提出一种基于贪心策略的LED灯珠组合和连接优化算法,达到节省物料的目的。实例结果证明,所提方法简单、可行,布局和分组效果好,算法收敛速度快,可用于解决实际工程问题。The distribution and grouping of planar LED can be modeled as a multi constraint optimization problem.A novel algorithm based on the centroidal capacity-constrained power diagram for LED distribution is proposed,to achieve the goal of uniform illumination of planar LED.An optimization algorithm of LED combination and connection based on the greedy strategy is proposed to save materials.The experiment results show that the proposed algorithms are simple,effective in layout and grouping with rapid convergence,and can be used in practical applications.
