Touch dimmable LED filament light bulb (based on 8022W solution)

Overview

All you need is an old low-current 5V USB charger. It
is very convenient for home use or taking out.
It can be used to directly use your own circuit to secondary design a better-looking appearance.
It can also be used for novices to learn principles and welding skills.
The design is inspired by the shape of the classic incandescent light bulb. The slanted arrangement of the LED filaments is also derived from the style of the internal filaments of the incandescent light bulb. It uses four 26mm LED filaments. It has no video flicker and does not tire your eyes.
It is as bright as a 40W incandescent light bulb, and it is warm and not hot for long-term operation. , multiple colors of filaments are available, which look great when matched with the PCB of the corresponding color solder mask
. Note: When welding the filament, the side of the small hole on the pin corresponds to the side of the PCB with dots in the solder resist.
