摘　　要：针对摄像头补光LED(Light Emitting Diode,LED)阵列的布阵优化及电路连接问题,研究了LED的串联阵列、并联阵列以及混联阵列的电路模型,分析了各自的构成特征及可靠性。理论分析与实验结果表明:先并后串的混联网状式LED阵列具有较高的可靠性,能延长阵列寿命,易于与驱动电源匹配,可广泛应用于摄像头补光。Considering that optimizing LED array and its circuit, LED array circuit model such as series connection, parallel connection and series - parallel connection are studied. The composition of their characteristics and reliability are analyzed. Theoretical analysis and experimental results show that mixed-linked-type LED arrays by parallel after series have a high reliability and can extend the life of the array. It can also be widely used in cam- era fill light.
