摘要
研究了应用于照明光源的LED阵列分布方式并基于MATLAB软件进行了仿真。首先对2种LED阵列的照度叠加进行了计算,根据叠加公式对阵列分布进行了仿真。通过对2种LED阵列仿真结果的分析,得出了不同阵列的分布特点并对其进行了比较,最后分析了2种不同阵列分布的产品适用性,为LED灯具设计提供了可靠依据。
LED has inherent characteristics, such as vibration resistant, energy saving, no pollution, with luminous efficiency improving, LED application is constantly expanding, in particular, which has broad prospects in lighting. As the power of a single LED is very small, but in lighting, the uniform flux and illuminance in a certain region are required, so it is necessary to use LED array for increasing the brightness and luminous area and improving the uniformity of illuminance. The text firstly calculates LED array illuminance, and then according to formula, it makes simulation to the LED array and analyzes simulation results, which obtains the distributed characteristic of the different arrays and compares two kinds of arrays the characteristics. Finally it finds the suitable arrays to the different kinds of lamps and provides accurate reference for designing LED lamps.
