Design of uniform LED light source

  • 摘要: 为了满足数字摄像法能见度测量仪均匀光源的要求,提高半导体发光二极管照明的均匀性,该文提出一种基于数字图像分析技术的设计方法。首先测量单颗LED在模组区域的亮度分布,进而拟合分布函数,再运用多颗LED亮度叠加原理,计算出不均匀度最小的多颗LED阵列方式,或固定均匀度对应的最佳尺寸。对仿真数据和实测数据进行对比分析,结果表明,该文计算出的LED阵列方式,与单边阵列相比,均匀度显著提高,最高可达95%以上。
    Abstract: In order to meet the requirements of uniform lighting in visibility meter using the digital camera method and improve the uniformity of LED lighting, a design method based on digital image analysis technique was presented. Firstly,according to the measurement of the brightness distribution of a single LED in the module area, the distribution function was fitted. Then by using the principle of brightness superposition, the arrangement of the multi-LED module with the lowest inhomogeneity or the best size of a fixed uniform was calculated. Furthermore,the simulated data and the measured data were comparative analyzed. Experimental results show that the uniformity is improved significantly in the arrangement of multi-LED module proposed in this paper, compared with in unilateral arrangement. The highest uniformity is above 95%.
