摘　　要：机场跑道临时关闭警示灯的光强分布对飞机的引导至关重要。考虑到警示灯构型、布局等因素的影响,提出了基于单灯光强分布模型的警示灯的整体光强分布算法。实验结果表明,该方法得到的光强分布与实测的吻合度在98%以上,与单灯叠加方法相比,其准确性提高了6%以上。The light intensity distribution of warning light for the temporary closure of airport runway is critical to the guide of aircraft. In view of the effects of configuration, layout, and other factors of warning lights, one algorithm for calculating the whole luminous distribution of warning light is proposed based on the light intensity distribution model of single lamp. The experimental results indicate that the fitting degree between light intensity distribution obtained by this method and that from the practical measurement is larger than 98%, and the accuracy here is improved by more than 6% compared and with that from the superposition method of single lamp.
