摘　　要：针对电梯专用LED应急照明的工作要求,分析了LED恒流驱动控制电源的特性。基于应急照明和LED驱动电路的基本原理,设计了电梯专用LED应急照明驱动电源。该电路具有交直流转化、可输出不同等级电压等性能,能够为LED应急照明灯提供稳定、持续的恒流电源,进而缩短了应急照明响应时间、稳定了照明强度、延长了照明时间、降低了能耗,在实际应用中得到了较好的效果。The characteristics of the LED constant current drive control power supply is analyzed for the working requirement of the elevator specific LED emergency lighting. Beyond this, based on the basic principles of the emergency lighting and LED driver, the power supply of the elevator is designed for the emergency lighting of LED. The circuit has properties of AC ! DC conversion and different output voltage levels, and it provides a stable and constant current power source for the LED emergency lighting, which reduces emergency response time, stabilizes lighting intensity, prolongs lighting time and reduces the energy consumption. The circuit obtained good effects in the practical applications.
