5050 RGB Addressable LED Chips — DMX512, SPI, and PWM Control for Professional Lighting

Product Overview

QUEENDOM’s 5050 RGB Addressable LED Chips combine full-color capability with intelligent control in a compact 5.0mm × 5.0mm ceramic package. Supporting industry-standard protocols including DMX512, SPI, and PWM, these chips enable sophisticated color mixing, dynamic effects, and pixel-level control for professional lighting installations.

With refresh rates exceeding 4000Hz and color consistency within ΔE<3, our addressable RGB chips eliminate flicker in broadcast and cinematography applications while delivering smooth gradients and precise color reproduction for architectural lighting, stage effects, and large-format LED displays.

Key Applications

Stage and Entertainment Lighting

Theatrical and concert lighting demands instant color changes, precise dimming curves, and flicker-free operation at any camera frame rate. Our 5050 RGB chips support DMX512 daisy-chaining for hundreds of fixtures with single-controller management, while 16-bit grayscale delivers smooth fades without visible stepping.

Architectural Facade Lighting

Building exterior lighting requires weather-resistant, long-life LED solutions that maintain color consistency across thousands of pixels over 10+ year installations. The ceramic substrate and advanced encapsulation of our 5050 chips resist UV degradation and thermal aging, maintaining ΔE<3 color uniformity across the installation lifetime. LED Video Walls and Displays High-resolution LED displays for retail, broadcasting, and public information require addressable pixels with tight optical and electrical matching. Our binned 5050 RGB chips deliver uniform brightness and color across entire display surfaces, with SPI interface supporting up to 1024 pixels per data line at 30fps refresh. Why Choose QUEENDOM Addressable RGB? • Multi-Protocol Flexibility: Single hardware platform supports DMX512, SPI, and PWM — simplify inventory and support multiple installation types • Tight Binning Control: Color and flux bins maintained within 3-step MacAdam ellipse and ±5% brightness • Broadcast-Safe Refresh: >4000Hz PWM eliminates banding and flicker in HD and 4K camera capture

• Thermal Reliability: Ceramic substrate with thermal resistance <2.5 K/J delivers consistent output in enclosed fixtures • Custom Firmware: Programmable gamma curves, color temperature mixing, and special effect patterns Certifications and Compliance CE | RoHS | REACH | IEC 62471 (photobiological safety) | LM-80 tested | FCC Part 15 Class B (for integrated controller variants) Related Products • 3535 Ceramic LED Chips (AEC-Q102) — Automotive-grade ceramic LEDs for extreme environments • 7070 High-Power Ceramic LED Chips — High-power single-color solutions for industrial illumination • SWIR LED Chips (970-1700nm) — Short-wave infrared for industrial vision applications Frequently Asked Questions Q: What is the maximum number of pixels per DMX512 universe? A: A single DMX512 universe supports 170 RGB pixels (512 channels ÷ 3 channels per pixel). For larger installations, multiple universes can be cascaded using DMX splitters or Art-Net/sACN converters. Our SPI interface supports up to 1024 pixels per data line, making it suitable for high-density displays. Q: Can I achieve white light by mixing RGB, and what is the CRI? A: RGB mixing can produce white light, but CRI is typically 60-70 because RGB LEDs lack continuous spectrum coverage. For high-CRI white applications, we recommend adding a dedicated white channel (RGBW) or using our tunable white solutions. We can provide spectral power distribution data to help you evaluate color rendering for your specific application. Q: What is the difference between 3-wire and 4-wire SPI? A: 3-wire SPI uses DATA, CLK, and GND lines with each pixel regenerating the signal. 4-wire SPI adds a separate chip-select (CS) or latch line, enabling individual pixel addressing and faster refresh rates. 4-wire is preferred for high-resolution displays; 3-wire is simpler for linear lighting strips and signage. Q: How do I prevent color shift over the product lifetime? A: Color shift is primarily driven by thermal degradation and current density. Our ceramic packages minimize junction temperature rise, and we recommend operating at ≤80% rated current for extended life. For critical color applications, we offer active temperature compensation firmware that adjusts drive currents based on real-time junction temperature sensing.
