Mains LED Circuit: 100-240V AC Schematic
Description
This is a straightforward and effective LED circuit designed for direct operation from an alternating current (AC) supply ranging from 100 volts to 230 volts. The circuit serves effectively as a mains power indicator or a nighttime lighting solution. The resistor R1, R2, and capacitor C1 provide the required current restriction. The circuit demonstrates resilience against voltage fluctuations and overloads.

Safety and Hazard WARNINGS:
This circuit operates with a dangerous power voltage. The circuit must be mounted within a protective casing prior to applying alternating current (AC) power. Modifications to the circuit are prohibited – a 10-minute wait period is required before any physical contact is made with the circuit after disconnection of the AC power. This circuit is not intended for use by children.
