08032011 I made a circuit for a 120volt AC night light.
120v led night light circuit diagram. One wire has the 100K 12W resistor. By shunting the power to the resistor so that any power savings are imaginary. It LOOKS like it turns off.
This device has three circuits. 23092019 This is simplest automatic solar night light circuit that my son try to make it for basic small solar charger. So the circuit uses only about 110 as much current while the LED is off.
The capacitor C1 and resistor R1 forms the current limiting circuit. This circuit is a simplest circuit. The Circuit Diagram for LEDs in Parallel Connection is shown in the following image.
16102010 Here is the circuit diagram of a super bright LED night lamp that can be operated from the mains supply. 09122019 LED diode connected to 110120 Volts 60 Hertz Xc 1 2 p f C 1 2 x 31416 x 60 x 047uF 5646 ohms I VXc 1205646 213mA With a 047uF non-polar capacitor the reactance will be 5646 ohms and the current through the LED or LEDs will be 213mA milliamps. Solder the Resistor and the Diode to the Two Bulb Wires.
After checking connections connect the transformer to a mains outlet and if all goes well the LEDs. Since the capacitor must pass current in both directions a small diode is connected in parallel with the LED to provide a path for the negative half cycle and also to limit the reverse voltage across the LED. He trial it to learn about solar LED light and makes it all by himself.
The Switching Circuit. In this circuit we will try to connect three 5mm White LEDs in parallel and light them up using a 12V Supply. Bridge D1 is used to rectify the AC mains voltage.
