AC mains operated single LED flasher circuit, built using the popular CMOS timer chip TLC555 is shown below. The whole circuit is powered directly by the grid supply of 230VAC through a capacitive ...

This is probably the simplest idea to generate flashing light from an LED using AC. The circuit is relatively the simple way of flashing one or more LEDs from a high voltage DC obtained from Mains.

Optical and scanning electron microscope images of a nano-LED device that uses AC power instead of DC power, which could be a game-changer for sharper near-eye displays. WASHINGTON, Nov. 4, 2025 — ...
