Introduction

SK6805-2427 is an intelligent LED light source that integrates a smart control circuit and a light-emitting circuit into a single component, with a form factor similar to a 5050 LED. Each lighting element functions as one pixel, with pixel brightness controlled by a smart digital interface input. The output is driven by a patented PWM technology to ensure high color consistency across pixels. The control circuit consists of a signal shaping and amplification circuit, a built-in constant current circuit, and a high-precision RC oscillator. It uses a unipolar NRZ communication protocol, where 24-bit data is transmitted from the controller to the DIN port of the first element and extracted pixel by pixel upon reception. After internal data latching, the remaining data is output from the DO port to subsequent pixels via the internal amplification circuit. The pixel resets after the DIN signal ends. With auto-reshaping and retransmission technology, the number of cascaded pixels is limited only by signal transmission speed. This LED features low drive voltage (energy-efficient and eco-friendly), high brightness, wide dispersion angle, excellent consistency, low power consumption, and long lifespan, with the control circuit fully integrated inside the LED.
