LED display ac line indicator circuit

This circuit is compatible with the main power is 115 Vac or 230 Vac.It shows that the power grid or not.And while the switch will still hold the power or not.
Operation of the circuit. be This circuit is the main indicator of power while not pressing the switch S1. Will have current flowing through R1, D1,LED1 will light up to reflect the input of the power is. But when the press switch S1 will flow through R2, D2,LED2. It makes LED2 light and also a part of current flow to trigger B pin of Q1. It makes Q1 work as a short LED1 to ground. Makes LED1 off.

LED Lights for AC line

LED current is derived directly from the mains via a diode-capacitor circuit.
Reverse engineered circuit diagram of an LED night light made by a north american manufacturer. Remarkably it only draws 100mW and has some surge voltage immunity. A clear plastic light pipe is used to diffuse the light from the LED into the room.

LED Indicator for remote AC loads

The LED Indicator for remote AC loads Circuit. At very cheap and use electronic part the a little. This circuit uses diode rectifier cheapness , Resistor and LED only. As a result assemble the circuit shows flowwing of AC current Source in load easily. Although intend to design for apply to office implement with main electric , but we may modify this idea goes to are usable with the level low voltage get not difficult please.
