This reference design converts 90V AC to 135V AC input, and drives seven, or eight series connected LED s from 300 to 600 mA average current. The LM3445 switching frequency is set at a nominal 225 kHz. This is a four layer board using the bottom and top....

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 light. To control the Triac, and the brightness of the lamp next. Suppose low light so there is....
-
The circuit works by varying the firing angle of the Triac. Resistors R1, R2 and capacitor C2 are associated with this. The firing angle can be varied by varying the value of any of these components. Here R1 is selected as the variable element. By varying....

This circuit operates at potentially lethal 220V AC mains voltage. The circuit should be built and used only by people who know hot to safely work with such dangerous voltages and how to built the circuit so that it is safe to use. Solid-state light dimmers....

This handy circuit can be used as a speed controller for a 12V motor rated up to 5A (continuous) or as a dimmer for a 12V halogen or standard incandescent lamp rated up to 50W. It varies the power to the load (motor or lamp) using pulse width modulation....

The triac should flip on and the light and it should be at nearly 100% brighness. However, this is not what`s happening. Itstead, the light doesn`t turn on at all. Can anyone explain why this might be If I change the gate to be always triggered (i. e. always....

Making a light-dimming control system for a 240V heat lamp dissipating around 250W. I need to adjust the heat output on the lamp by control from a microprocessor. I`m developing on an 8051-based SoC with RF circuitry and some sensors and actuators. Basically....

The light is simply blinking instead of dimming. So I used the following software to just glow the bulb without dimming: unsigned int i=1; void setup() { Serial. begin(9600); pinMode(AC_pin, OUTPUT); pinMode(11, OUTPUT); attachInterrupt(0, light, RISING); }....

The lighting source (i. e. bulb, tube light) glow according to their specified watt rating. If we need more light then we have to use high watt bulb at the same place if we need low light we have to replace high watt bulb with low rating. But What if there....

The timer is triggered on the zero crossing voltage pulse. The time constant is determined by C5/R14+R15 that is used to determine the conduction angle. The T2 T3 inhibits the power switch until the auxiliary supply voltage reaches 8V to guarantee that the....

The circuit of a simple triac light dimmer shown below can be used for dimming incandescent lamps directly from AC mains. The circuit is very easy to construct and uses very few components. The pot is used for controlling the load power or the intensity of....

This super-simple dimmer consists of only two components, and it can easily be built into a mains switch. If you do this, don`t forget torst switch off the associated branch circuit in the fuse box, since the mains voltage is always dangerous! The circuit....

This is yet another project born of necessity. It`s a simple circuit, but does exactly what it`s designed to do - dim LED lights or control the speed of 12V DC motors. The circuit uses PWM to regulate the effective or average current through the LED array,....
