摘要: 讨论LED光源的半光强角对LED之间的最大间距的影响，采用Matlab软件对LED单元照度数据进行计算及仿真，给出相应的仿真图形。仿真结果表明:LED光源之间的最大间距与其功率无关，由于仿真的结果与理论计算值相吻合，说明在计算中所建立的LED的光学模型具有较高的可信度，所得结果为LED多阵列（如圆形，矩形，椭圆等）的仿真及应用设计奠定了理论基础。Abstract: The impact of the different half-intensity light angles on the LED array maximum interval was discussed. The illumination data of LED unit was calculated and simulated using Matlab. The corresponding simulation graphics were given. The simulation results show that the maximum interval between the LED light sources is independent of the power. Since the simulation results agree with the theoretical values, the LED optical model established in the calculation has good credibility. These results are useful in the modeling and application of LED multiple arrays such as round, rectangular and oval.
