Description

Automatic light-putting-out energy-saving switch
The utility model is a kind of automatic light-off power down switch, belongs to a kind of electric switch.
In energy-intensive today, the altar lamp of public places such as corridor, public lavatory has caused huge energy waste.For addressing this problem, people have studied many methods, but often element makes its cost higher owing to using.
The purpose of this utility model is: design the automatic light-off power down switch that a kind of circuit is simple, cost is low, result of use is good.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is Facad structure figure of the present utility model;
Fig. 2 is structure figure of the present utility model;
Fig. 3 is the contained line map of the utility model; Wherein:
1-plate face, 2-wiring board, K-flexible keypad, C-electric capacity, D 1～D 3-diode, D 9-light-emitting diode, R 1～R 4-resistance, the SCR-controllable silicon.
The utility model is made up of plate face (1), flexible keypad (k) and wiring board (2). Wherein, flexible keypad (k) is fixed on the outside of plate face (1), and has a spring to do support between the two, and wiring board (2) is installed in plate face inboard, by the circuit that is made up of electric capacity, resistance, diode and controllable silicon, wherein includes by diode D on it1～D 4The bridge rectifier that forms. Click flexible keypad (k), the circuit on the wiring board (2) just enters Delayed conducting automatic control duty. The input of circuit at first connects the input of rectification circuit, and the positive pole of rectification circuit output end connects the positive pole of controllable silicon SCR, controllable silicon SCR negative The utmost point connects diode D8Positive pole. Diode D5、D 6Rear and the resistance R of series connection2Parallel connection, the other end of this circuit is connected on the negative pole of rectification circuit. One circuit is arranged in addition, and it is by capacitor C and resistance R2After the parallel connection, successively with resistance R1With diode D7Series connection, wherein, capacitor C and resistance R3The negative pole of another termination rectification circuit, resistance R1Meet diode D7Positive pole. The control utmost point of controllable silicon SCR is connected to diode D7Negative pole, and diode D8Be connected across resistance R2With diode D7Between, and diode D7、D 8Negative pole join. Flexible keypad (k) is connected between the positive pole of the positive pole of rectification circuit and capacitor C. Resistance R4With light emitting diode D9After the series connection, be connected in parallel on the diode D in the rectification circuit1On.
During use, press flexible keypad (K), by rectification circuit, resistance R3With the charging circuit conducting of capacitor C composition, and charge to capacitor C rapidly. After the voltage on the capacitor C reached certain numerical value, electric current passed through resistance R1, diode D7Inject the control utmost point of controllable silicon SCR, when Injection Current is equal to or greater than the minimum trigger current of controllable silicon SCR, the controllable silicon SCR conducting, bulb is lighted. Along with the conducting of controllable silicon SCR, the voltage rapid decrease of charge circuit, charging stops automatically. After unclamping flexible keypad (K), capacitor C is passed through resistance R1, diode D7Continuation is powered to the control utmost point of controllable silicon SCR, and through resistance R2, diode D5、D 6To the negative pole of electric capacity, form the time-delay still conducting of controllable silicon SCR this moment of discharge back, bulb continues to light, and when discharge current during less than the minimum trigger current of controllable silicon SCR, controllable silicon ends, and bulb cuts off the power supply and extinguishes. When circuit is not worked, diode D1On voltage then pass through resistance R than height4After the step-down, make light emitting diode D9Conducting and luminous indicating switch position, and behind circuit turn-on, diode D1On the voltage rapid decrease, light emitting diode D then9Automatic distinguishing. In this circuit, diode D8Play the effect of temperature-compensating, effectively improved the stability of time-delay.
Of the present utility model simple in structure, cost is low, and result of use is good, and can adjust delay time by changing circuit parameter, has stronger applicability.
