Circuit employs two groups of voltage comparator first voltage comparator COMP1A and the second voltage comparator COMP1B.That be connected with the first voltage comparator COMP1A in-phase input end is piezoelectric ceramic piece B and the first resistance R2.What be connected with the first voltage comparator COMP1A inverting input is that vibration sensitivity regulates slide rheostat R3, for regulating the sensitivity detecting vibration, the intensity both vibrated.When enough strong vibration transfers the signal of telecommunication to through piezoelectric ceramic piece B, first voltage comparator COMP1A in-phase input end voltage ratio anti-phase input terminal voltage is high, the signal output part voltage of the first voltage comparator COMP1A becomes high level, and when not vibrating, the signal output part of the first voltage comparator COMP1A is low level.That be connected with the second voltage comparator COMP1B in-phase input end is infrared receiving tube D2 and the second resistance R1.What be connected with the second voltage comparator COMP1B inverting input is that infrared sensitivity regulates slide rheostat R5, detects ultrared sensitivity, the both distance of reflecting object for regulating.Second resistance R1 provides electric current for infrared transmitting tube D1.When not receiving the infrared ray of reflection (unmanned close), infrared receiving tube D2 resistance is larger, the voltage ratio anti-phase input terminal voltage of the second voltage comparator COMP1B in-phase input end is low, second voltage comparator COMP1B output is low level, when receiving enough strong infrared ray (have people close), infrared receiving tube D2 resistance decreasing, the second voltage comparator COMP1B in-phase input end voltage rise, makes the second voltage comparator COMP1B output be high level.
The output of the first voltage comparator COMP1A and the second voltage comparator COMP1B is connected to the signal input part of AND circuit 74LS08.When vibration and infrared ray being detected at the same time, two inputs of AND circuit are high level, and AND circuit exports high level, is that the 3rd electric capacity C3 charges by diode D3.When two inputs of AND circuit have one not to be high level, the signal output part of AND circuit is low level, and when diode D3 is used for preventing AND circuit output low level, the 3rd electric capacity C3 is discharged by AND circuit.3rd electric capacity C3 and delay adjustment slide rheostat R6 forms RC delay circuit, and the time of time delay can be adjusted by delay adjustment slide rheostat R6R6.After 3rd electric capacity C3 charges, field effect transistor M1 conducting, light-emitting diode D4 works luminous (namely desk lamp lights), when vibration and infrared ray not detected, AND circuit output low level, the 3rd electric capacity C3 discharges until its both end voltage is 0, field effect transistor M1 grid voltage declines gradually through delay adjustment slide rheostat R6, the field effect transistor M1 cut-off when its cut-in voltage lower than field effect transistor M1, light-emitting diode D4 closes (i.e. desk lamp extinguishing).
When the utility model normally uses, when nobody is close to desk lamp, the first voltage comparator COMP1A, the equal output low level of the second voltage comparator COMP1B, therefore AND circuit output low level, 3rd electric capacity C3 both end voltage is 0, field effect transistor M1 cut-off, and desk lamp is not luminous.When have people close to time, the slight vibration of generation makes the pressure on piezoelectric ceramic piece B change, and make first voltage comparator COMP1A export high level; When human body is near infrared ray, the infrared ray that infrared transmitting tube D1 launches reflects through human body, makes infrared receiving tube D2 can receive the infrared ray reflected back, and the second voltage comparator COMP1B exports high level.Now, the input of AND circuit is high level, and AND circuit exports high level, and the 3rd electric capacity C3 in RC delay circuit charges, and field effect transistor M1 conducting simultaneously, desk lamp is lighted.After people leaves, AND circuit output is low level, and the 3rd electric capacity C3 begins through delay adjustment slide rheostat R6 and discharges, and after setting-up time, field effect transistor M1 ends, and desk lamp is closed automatically, and the time can be set as 10 minutes.
The beneficial effects of the utility model are that desk lamp is easy to use, without the need to manually; Vibrate the trigger mechanism reliability be combined with infrared ray higher; Adopt electronic component as switch, the life-span is longer; Automatic delay function, avoids the frequent switch in the short time, saves energy; Circuit part adopts conventional electronic component, and cost is lower.
