Worldsemi WS2813-5050 Addressable RGB SMD LED Chip
WS2813 is a intelligent control LED light source that the control circuit and RGB chip are integrated in a package of 5050 components. It internal include intelligent digital port data latch and signal reshaping amplification drive circuit. Also include a precision internal oscillator and a 12V voltage programmable constant current control part, effectively ensuring the pixel point light color height consistent.
Dual-signal wires version, signal break-point continuous transmission, in the case of damage to a single pixel, without affecting the overall color display, built-in resistors and capacitors, without any external devices, and built-in anti-reverse circuit.
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. Every pixel adopts auto-reshaping transmit technology, making the pixel cascade numbers are 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. Integrated circuit chips enable the circuit control simpler, neater and more reliable.
