背景技术 Background technique
有很多公共场所的走廊和住楼房的人们在自家门前安装了各种各样的延时照明灯。如：声控延时延时照明灯，它使用起来的确很方便，可以达到节约能源的目的。但有时也常常事与愿违，这种声控开关延时照明灯非常灵敏，周围稍有声响就会动作，比如邻居家开门、关门的声音，附近有放鞭炮的声音、甚至楼下汽车鸣笛等声音，都会让声控延时延时照明灯亮起来，不仅不能节电，还会因频繁亮灯而影响到白炽灯泡的使用寿命。尤其在您深夜回家时，需要点亮这种声控路灯，就必须人为制造出声响，这种控制方式确实有碍夜间周围邻居们的休息。为了克服声控延时延时照明灯存在的种种缺陷，本实用新型所述的触摸式延时灯开关是将声控控制方式改成手触方式，经实际使用效果很好。触摸式延时灯开关有着电路结构简单、工作可靠性好等特点。可以直接取代普通照明灯的电源开关，安装时不必破坏或改动原有的电路布线。Corridors in many public places and people living in buildings have installed various time-delay lighting lamps in front of their houses. Such as: voice-activated delay delay lighting, it is really convenient to use, and can achieve the purpose of saving energy. But sometimes things are often counterproductive. This kind of voice-activated switch delay lighting is very sensitive, and it will move when there is a slight sound around it, such as the sound of neighbors opening and closing the door, the sound of firecrackers nearby, and even the sound of cars honking downstairs. It will make the voice-activated delay lighting lamp turn on, which not only cannot save electricity, but also affects the service life of incandescent bulbs due to frequent lighting. Especially when you go home late at night, if you need to light up this voice-activated street lamp, you must artificially make a sound. This control method really hinders the rest of the neighbors around at night. In order to overcome the various defects of the sound-activated time-delay lighting lamp, the touch-type time-delay light switch described in the utility model changes the voice-activated control mode into a hand-touch mode, and the actual use effect is very good. The touch delay light switch has the characteristics of simple circuit structure and good working reliability. It can directly replace the power switch of ordinary lighting lamps, and there is no need to destroy or change the original circuit wiring during installation.

实用新型内容 Utility model content
发明目的及有益效果：为了克服声控延时延时照明灯存在的种种缺陷，本实用新型所述的触摸式延时灯开关是将声控控制方式改成手触方式，经实际使用效果很好。触摸式延时灯开关有着电路结构简单、工作可靠性好等特点。可以直接取代普通照明灯的电源开关，安装时不必破坏或改动原有的电路布线。Purpose and beneficial effects of the invention: In order to overcome the various defects of the voice-activated delay lighting lamp, the touch-type delay light switch described in the utility model changes the voice-activated control mode into a hand-touch mode, and the actual use effect is very good. The touch delay light switch has the characteristics of simple circuit structure and good working reliability. It can directly replace the power switch of ordinary lighting lamps, and there is no need to destroy or change the original circuit wiring during installation.
电路工作原理：在触摸式延时灯开关电路中220V交流电经全桥整流元件QZ整流、电阻R2限流和状态指示发光二极管及稳压二极管DW稳压形成12V稳压电路，用于供给触摸信号放大电路。当触摸电极CM无信号输入时，PNP型晶体管VT2 、NPN型晶体管VT1和单向晶闸管SCR均处于截止状态，因流过照明灯HL的电流很小，不足以点亮照明灯HL。当手指触摸触摸电极CM后，人体感应信号经PNP型晶体管VT2放大，放大后的感应信号经开关二极管D1整流和电解电容C1滤波后得到2V以上的直流电压，使NPN型晶体管VT1导通，进而使单向晶闸管SCR导通，使照明灯HL点亮。Circuit working principle: In the touch-type delay light switch circuit, the 220V AC is rectified by the full bridge rectifier element QZ, the resistor R2 is current-limited, and the status indicator light-emitting diode and the voltage regulator diode DW are stabilized to form a 12V voltage regulator circuit for supplying touch signals. amplifying circuit. When there is no signal input from the touch electrode CM, the PNP transistor VT2, the NPN transistor VT1 and the one-way thyristor SCR are all in the cut-off state, because the current flowing through the lighting lamp HL is too small to light up the lighting lamp HL. When the finger touches the touch electrode CM, the human body induction signal is amplified by the PNP transistor VT2, and the amplified induction signal is rectified by the switching diode D1 and filtered by the electrolytic capacitor C1 to obtain a DC voltage above 2V, so that the NPN transistor VT1 is turned on, and then The one-way thyristor SCR is turned on, and the lighting lamp HL is turned on.
在NPN型晶体管VT2导通后，电解电容C1中所充的电荷不能立即释放完，电解电容C1通过电阻R3缓慢放电可使NPN型晶体管VT1导通并维持一段时间，所以使照明灯HL继续发光，当电解电容C1放电结束后，NPN型晶体管VT1截止，使单向晶闸管SCR也截止，照明灯HL熄灭。After the NPN transistor VT2 is turned on, the charge in the electrolytic capacitor C1 cannot be released immediately, and the slow discharge of the electrolytic capacitor C1 through the resistor R3 can make the NPN transistor VT1 turn on and maintain it for a period of time, so that the lighting HL continues to emit light , when the discharge of the electrolytic capacitor C1 ends, the NPN transistor VT1 is cut off, so that the one-way thyristor SCR is also cut off, and the lighting lamp HL goes out.
