摘　　要：为实现航空障碍灯产品长寿命及离线或在线通信,依据相关标准要求,采用红光LED光源设计了一种长寿命航空障碍灯。介绍了其AC/DC开关电源、DC/DC恒流驱动、环境光监测、闪光频率调节等电路设计,通过微控制单元(MCU)检测与控制、故障报警等功能设计,确保航空障碍灯长时间可靠工作。To improve the product life and keep offline or online communication with aeronautical obstacle light locally and remotely, a novel long-life aeronautical obstacle light is developed by using red LED light source according to the requirements of relevant standards. The circuit design of AC/DC switching power supply, DC/DC constant current drive, ambient light monitoring and flashing frequency adjustment are introduced. Based on the function of microcontroller unit(MCU) detection and control, RS485 communication and fault alarm, the aeronautical obstacle light can work reliably for a long time.
