How does WS2812B addressable LED strip light work?

WS2812B LED is an upgraded version of the traditional built-in driver IC, which has a more distinctive effect on performance stability, data transmission speed, heat dissipation capacity, etc. By integrating the driver IC inside the SMD5050 LED, avoiding a large number of LED external chips, capacitor-resistor arrangement occupies a lot of space, shortening the distance of data transmission while bringing the driver IC and SMD LED closer. WS2812B addressable LED strip supports DC5V low input voltage (which can work with DC5V USB LED power adapter), individually addressable (single LED can be cut), has higher brightness and purer luminous color than ordinary LEDs. 

What we need to know before buying？

Any damage to the LED will cause the entire LED strip to not light up and require more power input (5m needs power supply at both ends) to avoid voltage drop caused by over long distance. WS2812B LED strip works with Arduino UNO development board / Raspberrypi or dream color controller can work together to adjust 256 levels of brightness scale, output 16 million kinds of light color, produce dynamic color chasing (running horse lighting effect). WS2812B programmable LED light strip is one of the LED light strips with a wide range of applications at present. It has certain advantages in cost. We provide you with a variety of customized light strip lengths, widths, waterproof grades, LED density, etc to choose from, which issuitable for Indoor and outdoor engineering lighting.
