The 220V AC power obtains the 5V direct voltage and uses for chip U1 in the pulse generating circuit 1 and the chip U2 in the adjusting control circuit 2 after resistance R 3 step-downs, diode D1 rectification, voltage-stabiliser tube Z voltage stabilizing and capacitor C 1 filtering.
When the switch S closure, 3 pin of chip U1 in the pulse generating circuit 1 are exported a continuous square-wave signal, 2 pin for the chip U2 in the adjusting control circuit 2 use, its frequency is by potentiometer W, resistance R 1, capacitor C 2 decisions, regulator potentiometer W can regulate its frequency within the specific limits, thereby plays the gradually secretly effect of time of adjusting; When switch S disconnects, do not quit work owing to 8 pin of chip U1 have working power, its 3 pin is exported a high level signal, makes 2 pin of chip U2 remain high level, the trigger impulse phase angle of the 8 pin output of chip U2 remains unchanged, and can be used as general desk lamp with dimmer switch and use this moment.
When half press control button 6, sensitive switch AN1 action, this moment as long as the duration greater than 32 milliseconds during less than 332 milliseconds, 8 pin of chip U2 are just exported the negative sense spike, driving bidirectional triode thyristor BG conducting, bulb L is just lighted; Press 6 duration of control button during when half greater than 332 milliseconds, circuit is the light modulation operating state, the trigger impulse phase angle of 8 pin of chip U2 output changes at 41 degree to consecutive periods between 159 degree, and according to the esthesis of human eye, three processes are divided into soon, have a rest slowly and temporarily.When half pressed control button 6 end, phase angle was remembered when the brightness of chip U2 inside was remembered this.At this moment, if apply greater than 32 milliseconds, move less than 332 milliseconds partly press, 8 pin of chip U2 are just exported high level, and bidirectional triode thyristor BG is ended again, and bulb L just extinguishes, and circuit is closed condition.The control logic part control phase angle of chip U2 inside is still by the memory of this part, guarantees circuit when opening next time, the phase angle before keeping closing, and light source keeps former brightness.2 pin of chip U2 have gradually dark function, when the trigger impulse phase angle maximum (159 °) of 8 pin of chip U2 output, 3 pin of chip U1 impose on 83 pulses to 2 pin of chip U2, the trigger impulse phase angle of the 8 pin output of chip U2 fades to 40 °, final coutoff (not exporting trigger impulse) continuously from 159 °.
Because the chip U2 in the adjusting control circuit 2 has the brightness memory function, when gradually putting out end, when circuit is in closed condition, wants to light bulb, must grow and press sensitive switch AN1, makes bulb L by secretly brightening gradually, can not satisfy one by being bright demand.Therefore, increased the sensitive switch AN2 of a single-pole double throw, when needs one when being bright, need make sensitive switch AN2 action once earlier, circuit is cut off the power supply and discharge, make the brightness reminiscence in the chip U2 arrive the brightest, touch sensitive switch AN1 more once subsequently, lamp is lighted.
Be provided with connecting rod 64 prejudicially in the control button 6 in the utility model, make button 63 be distributed in active force difference on sensitive switch AN1, the AN2, reach two sections controls of control button 6.When button 63 is pressed, touch sensitive switch AN1 earlier, sensitive switch AN2 is touched in the back.When decontroling button 63, discharge sensitive switch AN2 earlier, the back discharges sensitive switch AN1, will regulate gradually secretly potentiometer W and the switch S of time simultaneously and combine, and forms rotatable two sections buttons.
In the utility model, the model of chip U1 is ICM7555, and the model of chip U2 is NB7232.
More than show and described basic principle of the present utility model and principal character and advantage thereof.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
