Product Attributes

Introduction

This product is an intelligent externally-controlled LED light source with integrated control circuitry and illumination circuitry. Its dimensions are 5.0×5.4×1.6mm, with each component functioning as an independent pixel. Each pixel integrates an intelligent digital interface data latch, signal reshaping and amplification drive circuit, power regulation circuit, built-in constant current circuit, and high-precision RC oscillator. The output drive employs patented PWM technology to effectively ensure color consistency across pixels. The data protocol uses unipolar return-to-zero code communication. After power-on reset, the DIN port receives data from the controller. The first 24 bits received are extracted and latched by the first pixel, while the remaining data is reshaped and amplified internally before being forwarded through the DO port to the next cascaded pixel — each pixel reduces the signal by 24 bits. This LED offers the advantages of low-voltage drive, environmental friendliness and energy efficiency, high brightness, wide scattering angle, excellent consistency, ultra-low power consumption, and ultra-long lifespan. Integrating the control circuit directly onto the LED results in a simpler overall circuit, smaller footprint, and easier installation.

Features

• Integrated high-quality externally controlled single-wire serial cascade constant-current IC
• Control circuit and die integrated in SMD5050 package, forming a complete externally controlled pixel with uniform and consistent output
• Built-in data reshaping circuit; signal received at any pixel is reshaped before retransmission, preventing waveform distortion accumulation along the line
• Built-in power-on reset and power-off reset circuits; LEDs default to OFF at power-up
• Built-in grayscale adjustment circuit (256-level grayscale)
• Red channel driver with special processing for more balanced color mixing
• Single-wire data transmission, supports unlimited cascade
• Reshaping and forwarding enhancement technology; transmission distance between two points exceeds 10 meters
• Data transmission frequency up to 800Kbps; cascade count no less than 1024 pixels at 30 frames/sec refresh rate
