| 摘 要： | 通过设定发光二极管所在平面与探测面之间的距离、所设计阵列的发光二极管个数及发光角度等参数,依据斯派罗法则,利用Matlab对表达式进行计算.结合TracePro软件,对方形阵列、三角形阵列及环形阵列等3个常见的发光二极管平面阵列进行模拟仿真及对比分析.结果表明:由于排列方式不同,所得到的均匀照明的范围及所占面板空间也各不相同;三角形阵列可得到较大范围的平坦度和占用较小的面板空间.

| Abstract: | According to Sparrow′s criterion and using Matlab and optical software TracePro,we simulate and comparative analysis the three common LED planar array that is square,triangular and circular array by setting the three parameters: the distance between LED array and the detective screen,the number of LED array and the viewing angle of LED.As the LEDs are arranged in different ways,there have different range of uniform illumination distribution and space occupation.By comparison,the results show that the triangular array can produce a wider range of flatness and occupy little space |
