本实用新型技术解决方案为:包括高压钠灯管、电子镇流器,还包括微波传感模块、缓冲放大器、开关电路、延时器、三极管电流放大器和继电器及控制电路直流电源组成,微波传感模块的内置微波振荡器射频输出经环形天线发射,人体行走活动反射的多谱勒频率由模块内置检测器检测信号经放大器、限幅电路接入模块外围缓冲放大器至开关电路、延时器、三极管电流放大器和继电器,其继电器触点接入电子镇流器至高压钠灯管; 
其中,缓冲放大器由数字集成电路六非门的三个非门串联输入输出跨接反馈偏置电阻,开关电路由二极管倍压检波经一个非门反相整形,接入由两个非门构成的单稳态延时器。 
本实用新型产生积极效果是:楼道、走廊微波人体传感模块高压钠灯,光效高,亮度强,并起到人走灯灭的节电作用。 
附图说明

具体实施方法 
参照图1、2,本实用新型具体实施方法和实施例:包括高压钠灯管7、电子镇流器6,微波传感模块1、缓冲放大器2、开关电路3、延时器4、三极管电流放大器和继电器5及控制电路直流电源组成,微波传感模块1的内置微波振 荡器射频输出经环形天线发射,人体行走活动反射的多谱勒频率由模块内置检测器检测信号经放大器、限幅电路接入模块外围缓冲放大器2至开关电路3、延时器4、三极管电流放大器和继电器5,其继电器触点接入电子镇流器6至高压钠灯管7。 
图2,微波传感模块IC1采用型号RD627,其内置微波振荡器射频信号输出经环形天线T发射,当人体行走时反射的多谱勒频率由模块内置检测器检测输出信号经放大器、限幅电路接入模块外围由数字集成块IC2采用CD4069的三个非门a、b、c串联跨接反馈偏置电阻R1构成的缓冲放大器放大至开关电路二极管VD1、VD2与电容C1、C2倍压检波,经非门d反相整形为矩形脉冲信号,通过电容C3耦合触发由第五个非门e、第六个非门f和电阻R2、R3电容C4构成的单稳态延时器至电阻R4限流三极管VT1电流放大驱动继电器J,非门d输出为低电平时,使其触点JK吸合高压钠灯D通电,引燃发光。 
经过单稳态延时器电容C4对电阻R3放电的延时,触点JK释放,高压钠灯D断电自动熄灭,起到人走灯灭的节电作用。 
图中,控制电路直流电源是由电容C7电阻R6接入交流电源AC220V降压,经二极管VD5整流和VD4稳压,电容C6滤波,电阻R5与电容C5进一步滤波供给微波传感模块电源。并联在继电器J线圈两端的二极管VD3防护三极管VT1免受反向电压的冲击。
