LED cross-flow control chip: SY7203DBC
PWM signal source:GP9101-F20K-L2H1-SW
Lithium battery charging chip: IP2312
Dual-channel dimmable, high-power LED lamp, the casing uses a 50x21x150 aluminum alloy shell, one LED uses a 120x36 12Vcob package 10W LED light panel, and the other uses three 3535 3W LEDs connected in series. The battery uses an old battery that was replaced after the Xiaomi 10PRO mobile phone was sold. It is a 4.45V high-voltage lithium battery with relatively high power and can handle the high current of the LED.

3. 10W COB light panel
4. The 3WLED uses a copper strip for heat dissipation. The side of the copper strip is glued to the bottom of the LED aluminum substrate with thermal conductive glue and glued to the casing.
4. The side LED lights up
5. With the addition of a focusing cup, the brightness focus is quite good.
We are still missing an acrylic side panel and a cover for the COB light on the front, so I will tinker with it when I have time. The internal dimensions are utilized to the extreme. You can try it if you need it. Please turn off the switch when not in use to prevent battery leakage.
