Below describe in detail the light-operated delay illuminating lamp of acoustic control described in the utility model necessity involved in implementation process, guardian technique content.
Utility model content
Goal of the invention and beneficial effect: the light-operated delay illuminating lamp of acoustic control can directly replace common road lamp switch and need not change original illuminating line, by day or the stronger occasion of light, even if there is larger sound bulb to be lit, at night or dark time, run into the sound, as: the rear bulb such as voice, footsteps is lighted automatically, through about (time can set) automatic distinguishing after more than 30 second.It is applicable to stair, the place that corridor etc. only need the short time to throw light on.The circuit of the light-operated delay illuminating lamp of acoustic control all uses common components and parts to make, and cost of manufacture only needs tens yuan.
Circuit working principle: the light-operated delay illuminating lamp of acoustic control forms full bridge rectifier by rectifier cell QZ, 220V alternating current is become pulsating direct current by it, again through dropping resistor R5 current limliting, voltage stabilizing didoe DW voltage stabilizing, electrochemical capacitor C2 filtering export 9V direct current, for integrated circuit CD4011 and NPN type triode VT1 provides working power.
When daytime, light was mapped on photo resistance RG, its resistance becomes very little, the 1st pin making NAND gate IC1 is low level, output is locked into high level, the incoming level height of the 2nd pin of NAND gate IC1 is irrelevant, so circuit has blocked sound channel, make voice signal not by, namely bulb HL light on and off are not by Sound control.At this moment, NAND gate IC1 output is low level, and the not conducting of unidirectional thyristor SCR Triggerless, bulb HL does not work.
At night, photo resistance RG irradiates in high resistant because of dull thread, makes the input of NAND gate IC1 the 1st pin become high level, and the 2nd pin of NAND gate IC1 is by the control of incoming level, and this opens the condition of creating for sound channel.During the 2nd pin low level of NAND gate IC1, the 3rd pin of door NAND gate IC1 exports high level, and during the 2nd pin high level, the 3rd pin of NAND gate IC1 exports as low level.
When not having voice signal, NPN type triode VT1 is operated in saturation condition, and the 2nd pin of NAND gate IC1 is low level.When stair have people to walk about or have people to speak, microphone MIC picks up ground voice signal and amplifies through NPN type triode VT1, NPN type triode VT1 enters magnifying state by saturated, NPN type triode VT1 collector electrode is transformed into high level by low level and delivers to the 2nd pin of NAND gate IC1,3rd pin of NAND gate IC1 exports and charges to electric capacity C3 for high level, because charge constant is very little, make the 4th pin output high level of NAND gate IC1 very soon, trigger unidirectional thyristor SCR conducting by resistance R6, bulb HL is lighted.After sound disappears, the 3rd pin output low level of NAND gate IC1, because of the blocking effect of silicon rectifier diode D1, electrochemical capacitor C3 slowly can only be discharged by resistance R4, because the 4th pin of NAND gate IC1 keeps high level, makes bulb HL remain luminous.Through discharging after a while, when electrochemical capacitor C3 both end voltage drops to low level, the output of NAND gate IC1 the 4th pin becomes low level, unidirectional thyristor SCR Triggerless and turn off bulb HL is extinguished.
Circuit delay time is the time that bulb HL lights at every turn, it determines primarily of resistance R4 and electrochemical capacitor C3 discharge time constant, when resistance R4 is 1.5M Ω, when electrochemical capacitor C3 is 22 μ F, time delay about 30 seconds, the numerical value of increase and decrease resistance R4 or electrochemical capacitor C3, can the delay time of Circuit tuning.
