摘　　要：雷电活动是常见的自然现象,路灯安装于户外,遭受雷击的概率较大。LED路灯电源同时受到直击雷、感应雷的影响,因此,文章针对LED路灯电源设计了一套防雷方案,同时考虑了直击雷的巨大能量泄放、感应雷的电压和电流脉冲影响,以及共模和差模信号对于控制器的干扰等。可以提高LED路灯电源的雷电防护性能。Lightning activity is a common natural phenomenon, street lamps installed outdoors, the probability of being struck by lightning is high. LED street lamp power supply is affected by both direct lightning and inductive lightning. Therefore, this paper designs a set of lightning protection scheme for LED street lamp power supply, taking into account the huge energy release of direct lightning, the influence of voltage and current pulse of inductive lightning, and the interference of common mode and differential mode signals to the controller, which can improve the lightning protection performance of LED street lamp power supply.
