How do WS2811 addressable LED strip lights work?
WS2811 is a 3-channel LED drive control dedicated circuit, internal of the chip contains an intelligent digital interface data latch signal shaping and amplifying drive circuit, as well as a high-precision internal oscillator and a programmable stable current output driver. The chip adopts a single-wire return-to-zero code communication method, after the chip is reset on the line, the input data on the DIN terminal is controlled by an Arduino UNO development board or a dream color intelligent SPI controller, and the data is stored in the internal latch, the remaining data is amplified by the internal shaping process and then starts to forward the output to the next-level chip through the DO port to achieve high-speed data transmission, output 256-level grayscale adjustment, 24-bit color display and 16 millions dynamic color chasing effect, which is suitable for home lighting.
DC12/24V WS2811 LED strip has a high market share, low price, and a wider coverage of demand groups, which adopts high-quality flexible PCB with good heat conduction and heat dissipation performance; the internal integrated RGB LED chip and control circuit are in the SMD5050 component, with high brightness, wide viewing angle, purer color and flexible LED arranging structure, one IC can control 3/6 LEDs; the exterior is wrapped with epoxy resin layer, silicone sleeve , and waterproof plastic irrigation to achieve good waterproof effect of IP65/67/68; the back uses 3M tape, which has strong adhesion and is easy to install. At the same time, we provide personalized services such as customized length.
