This the circuit AC dimmer low voltage For lamp 6V. While this friends may don`t see the advantage of this circuit. But I thinks first step advantage be something get learn the work of Triac. And have tall safety, because of use AC Low Voltage. Which the.... -
This circuit has can to turn down a light bulb arrives at 100W. If Triac there is tall temperature should hold Heat Sink or let off the heat. The Diac be diode that perform be formed encourage or Trigger Diode 2 kinds are way or Bidirectional. The VR1 use.... -
This is an automatic light dimmer circuit. You do not need to dim the lights by yourself. It is so very convenient, because we use the LDR to detect external.... -
When change the value of R2 Intensity of Lamp change to this circuit shows the usability of Mosfet be Variable Resistor. By Q1 use N-Channel Power Mosfet. but what is the number all right follow the size of Load or Lamp there. When change the value of R2.... -
This circuit is DC Dimmer Circuit. By use IC LM555 be model Astable Multi vibrator. It is can change translate Duty Cycle with fining VR1 and VR2 be.... -
The super dimmer it is certainly better than the normal dimmer you are using now. It would be better, however, to try to prove it. Let`s see how it works.... -
When the potentiometer is at the up position, the capacitor will charge quickly through both 1k resistors and the diode, producing a short positive interval and long negative interval which dims the lamp to near darkness. When the potentiometer is at the.... -
Filament Light Dimmer Circuit This simple triac dimmer can be used to control incandescent filament lamps up to 200W. The circuit operates on.... -
Hi everyone! I found this circuit in my computer (i don`t remember where i got it and when) and i was wandering if it`s able to dim 220V LED BULBS? it .... -
Hello everyone, I need help to modify this light dimmer circuit which is connected to PIC12C508 microcontroller. This circuit is designed for the.... -
Hi folks. I`m new to the forum and relatively new to diy electronics. My current project involves trying to make a battery-powered LED dimmer circuit. .... -
This electronic lighting dimmer circuit is used to control the lamp for arbitrary brightness. This electronic lamp dimmer circuit work for incandescent lamp, not a fluorescent one. The dimmer circuit here work for both 110V and 220V AC. The dimmer circuit is.... -
This automatic light dimmer circuit makes it possible to control a lighting system so that it turns on or off slowly. The circuit works this way: when switch S1 is closed, the capacitor C1 is slowly charged. Once the voltage at C1 reaches 0. 6, transistor T1.... -
With IC SLB0586A from Siemens you can build a simple touch light dimmer circuit that will allow you to adjust the lamp intensity. Together with a TIC206D triac, it enables smooth regulation of light intensity from a bulb of 10W 400W. A coil of 100 µH/5A is.... -
The DIAC is a 28V bidirectional (bilateral) trigger device that is used on virtually all inexpensive phase controls. The trigger voltage is somewhat high for phase control of 115VAC. Years ago, there was a similar low voltage (6 to 8V) trigger device called.... -

This light dimmer control has active timing capacitor reset or AC line zero-crossing synchronization. The 13 additional components are garden variety and cost less than $2. Performance at the low end is exceptionally smooth and snap-free better even than the.... -
Chandelier Dimmer , Many of the chandeliers have a pull chord switch. Now add a novelty to your chandelier and surprise the guests. Place a small wire down the lamps from.... -
Remotely controlled light dimmers in theatrical and architechtural applications use 0-10V control signal for controlling the lamp brightness. In this case 0V means that the lamp is on and 10V signal means that the lamp in fully on. A voltage between those....
