What is WS2811 LED Strip?

The WS2811 is an external integrated circuit (IC) that is commonly used in LED strip lighting. Each WS2811 IC is capable of controlling one RGB LED, allowing for the creation of various lighting effects such as color changing and chasing patterns.

The WS2811 IC operates by receiving digital signals from a microcontroller, which can be programmed to send specific commands to control the color and brightness of each small group of LEDs. The IC then interprets the signals and sends the appropriate data to the corresponding LED.

A WS2811 LED strip is a type of addressable LED rope light that usually mounted on a flexible circuit board. The WS2811 LED strip can be programmed to create a wide variety of lighting effects, from static colors to dynamic patterns and animations.

Warum SunTechLite wählen?

Our Addressable LED light strips have the following main advantages:

  1. PCB thickness: SuntechLite uses 0.25mm and 0.35mm PCB for our regular strip lights. (The thickness of the general PCB on the market is 0.2mm.) The thicker the PCB board, the greater the current flowing, and the higher the efficiency of the light strip.
  2. High-quality Resistors: Authentic Guarantee, Antioxidant. DC12v LED strip generally uses 0.8mm*0.5mm resistors, DC24v LED strip generally uses 1.2mm*0.6mm resistors. This makes the strips have good heat dissipation, high temperature resistance, and very stable.
  3. Dual capacitor design: Dual capacitor design can protect the IC, and the signal transmission is stable.
  4. Firm light strip connection: Tin is added to the connection of the light strip, which is convenient for welding after cutting. The solder joints are full, and there will be no false welding.

Besides, we have a specialized engineering team to offer technical support and assistance with the installation and programming of the LED strips. And you can feel free to contact us if any questions in the using process.
