LED是21世纪的绿色光源,具有广阔的照明前景.近年来,LED灯具产品开发的种类越来越多,设计合适的LED灯具显得尤为重要.由于单颗LED的功率很小,作为照明来使用,要求在照明区域内具有一定的均匀光通量和照度,所以需要采用LED的阵列形式, 加大其发光亮度和发光面积,改善光照的均匀性.该文首先计算LED阵列的照度叠加,进而根据叠加公式对阵列仿真,分析两种LED阵列分布的仿真结果,得出不同阵列的分布特点,并比较两种阵列的特点,最后分析出不同阵列分布的适用灯具,为LED灯具设计提供可靠依据.

LED is one of the green light sources in the 21st century, and it has broad prospects in the illumination. In recent years, there have been more and more LED lamps, and designing appropriate LED lamps become very important. The power of a single LED is very small, but lighting requires the uniform flux and illuminance in a certain region, so it is necessary to use LED arrays for increasing the brightness and luminous area, improving the uniformity of illuminance. This paper calculated illuminance of the LED arrays at first, and then according to known functions, the LED arrays were simulated and analyzed. The distribution characteristics of the different LED arrays were obtained by comparing the characteristics of two kinds of LED arrays. Finally, the law of arrays suiting lamps was shown, which will be able to provide the accurate reference for designing LED lamps.
