WS2812 RGB LED Ring Lamp (1 Pc)

The WS2812 RGB LED Ring Lamp (1 Pc) is a compact circular LED lighting module that features individually addressable WS2812B RGB LEDs arranged in a ring. Each LED contains an integrated RGB LED and an intelligent driver IC, enabling independent control of every LED using a single digital data line. The module is widely used in Arduino projects, robotics, IoT devices, wearable electronics, smart lighting, decorative lighting, interactive displays, educational electronics, and DIY projects.

The LED ring is manufactured on a high-quality FR4 printed circuit board (PCB) and includes WS2812B 5050 RGB LEDs, onboard intelligent driver ICs, copper conductive traces, power and ground connections, Data Input (DIN) and Data Output (DOUT) pins, bypass capacitors, and mounting holes for easy installation. Multiple LED rings can be connected together in a daisy-chain configuration to create larger lighting systems.

The working principle of the WS2812 RGB LED Ring Lamp is based on single-wire serial communication. A compatible microcontroller or LED controller sends digital data through the DIN pin. Each WS2812B LED receives a 24-bit color value (8 bits each for Red, Green, and Blue), displays the assigned color, and forwards the remaining data to the next LED through the DOUT pin. This allows every LED on the ring to display different colors and brightness levels independently, creating dynamic lighting effects and animations.
