平板LED灯在电梯中的应用

Research and Application of Flat-Panel LED Lights in the Elevator

应节能减排的要求,设计了基于平板LED灯的电梯照明系统。其电路控制在满足常规照明控制需求外,还采用了驱动电流降额输出电路的应急照明模式。为延长电梯照明系统LED灯的使用寿命,对LED照明系统的散热问题进行了深入研究。研究结果表明,所设计的LED电梯照明系统不仅实现了节能环保,还延长了乘客在电梯故障情况下的安全照明时间。

For the purpose of energy-saving and emission reduction, the flat-panel LED based elevator lighting system was designed in this paper. To meet the demand for conventional lighting control, the circuit control was applied. In addition, the output circuit drive current derating based emergency lighting mode was designed. To extend the life of LED in the elevator lighting system, the heat dissipation of LED lighting system was detailed discussed. The results showed that the designed LED elevator lighting system can meet the demand of energy saving and environmental protection and extend the security lighting time of the passengers in the elevator malfunction case.
