本实用新型的目的是提供具有保护功能、安全可靠、功率因数、节能环保的无极灯。
本实用新型的目的通过以下技术方案来实现。
一种无极灯镇流器，其特征在于：所述无极灯包括灯壳和灯壳内的灯泡以及镇流器、镇流电路和电源线，灯泡为无极灯，灯泡通过电源线与镇流器电连接。
所述镇流电路包括滤波整流电路、功率因数校正电路、高频逆变电路、驱动电路和保护电路，电源经滤波整流电路整流后送功率因数校正电路获得高功率因数的直流电，该直流电经过由驱动电路控制的高频逆变电路产生高频高压的工作电压点亮无极灯；保护电路的输入端连接高频逆变电路输出端以检测无极灯的工作状况，输出端连接驱动电路，当出现异常情况时控制高频逆变电路的工作。
所述功率因数校正电路由功率因数补偿控制集成电路及其***元件组成。
所述保护电路包括电流和电压检测电路，电流和电压检测电路与驱动电路一体化成为驱动保护电路。
所述无极灯电源输入端串联一温度开关。
本实用新型与现有技术相比具有以下优点。
与传统的镇流器相比，本实用新型无极灯中的镇流器设有多种异常保护功能，包括超温保护、过流过压保护等，保障了无极灯使用安全可靠，而且延长了镇流器的使用寿命。镇流器还加入了功率因数校正电路，减小了无功功率，提高了电源的使用效率，更加节能环保。
附图说明
图1为本实用新型无极灯镇流器电路原理框图。
具体实施方式
下面结合附图对本实用新型无极灯镇流器作进一步详细描述。
