Explore the construction of a stylish desk lamp using 80 advanced 2835 LED beads with variable color temperatures: 3500k, 4000k, 5000k, and 5500k.
· Copper-clad board
· 2835 LED
· 7135
· 8022ws
· Mini USB female head
· Capacitor
· Fine copper tube
· Suction cup hook
Meticulously carve the board, carefully planning the LED layout, and drawing precise wiring before intricately carving the circuit.
Weld the four LED circuits, employing 7315 constant current drivers for separate control. Utilize 8022ws for PWM dimming control.
Connect the mini USB to a 5V power source for seamless functionality.
Establish a touch control system by connecting the 8022 touch pin to a copper tube, cleverly serving as both a support structure and a touch-sensitive control for dimming the LEDs.
Opt for a suction cup fixation method instead of a traditional base, effectively conserving valuable desktop space.
For detailed circuit diagrams, refer to online resources on 8022w/8022ws.
The circuit assembly is straightforward, with readily available circuit diagrams online. The primary challenges lie in meticulous board layout and carving.
The carved board
The circuit is roughly like this
Weld the four LEDs and drive components
Then weld the USB female head and touch bracket
Finally, attach the suction cups
