WS2812D-F5

WS2812D-F5-1261 Intelligent control LED integrated light source Features and Benefits     The control circuit and the LED share the only power source. Control circuit and RGB chip are integrated in a package of F5 plug-in components, to form a complete addressable pixel. Built-in signal reshaping circuit, after wave reshaping to the next driver, ensure wave-form distortion not accumulate. Built-in electric reset circuit and power lost reset circuit. Each pixel of the three primary color can achieve 256 brightness display, completed 16777216 color full color display, and scan frequency is of 2KHz. Cascading port transmission signal by single line. When the refresh rate is 30fps, cascade number are not less than 1024 pixels. Send data at speeds of 800Kbps. The color of the light is highly consistent, cost-effective.  Reverse-connection protection.      Applications  Full-color module, LED full-color soft/hard light bar, LED guardrail tube.  LED decorative lighting, LED Screen, Indoor/outdoor LED video irregular screen, various electronic products, electrical equipment marquee. General description WS2812D-F5-1261 is an intelligent external control LED light source that integrates control circuit and light-emitting circuit. Its appearance is the same as an F5 LED lamp bead, and each element is a pixel.It internal include intelligent digital port data latch and signal reshaping amplification drive circuit.Also include a precision internal oscillator and a voltage programmable constant current control part, effectively ensuring the pixel point light color height consistent. The data transfer protocol use single NZR communication mode. After the pixel power-on reset, the DIN port receive data from controller, the first pixel collect initial 24bit data then sent to the internal data latch, the other data which reshaping by the internal signal reshaping amplification circuit sent to the next cascade pixel through the DO port. After transmission for each pixel, the signal to reduce 24bit. pixel adopt auto reshaping transmit technology, making the pixel cascade number is not limited the signal transmission, only depend on the speed of signal transmission. LED with low driving voltage, environmental protection and energy saving, high brightness, scattering angle is large, good consistency, low power, long life and other advantages. The control chip integrated in LED above becoming more simple circuit, small volume, convenient installation. 1 http://www.world-semi.com WS2812D-F5-1261 Intelligent control LED integrated light source Mechanical Dimensions(Unit:mm) PIN Function NO.
