What are LED pixel strips? Common model specifications and control methods of LED pixel strips
LED pixel strips are LED light strips with three colors: red, green, and blue. By adjusting the brightness and mixing ratio of these three colors, various colors and lighting effects can be presented. Compared with single-color or two-color light strips, LED pixel strips have stronger expressive power and scope of application, and can be used in various occasions and purposes, such as home decoration, commercial advertising, stage performances, etc. LED pixel strips usually adopt digital control methods, such as DMX512, SPI and other protocols, which can achieve remote control and multiple light change modes. It is also usually called a magic light strip.

Common models of LED pixel strips:
LED pixel strips are classified according to lamp beads. The common ones are 2835LED pixel strips and 5050LED pixel strips.
It is obviously more reasonable to classify according to chip control. The following 5 common ones are
WS2812B: An RGB LED light strip based on WS2811. It has a built-in controller. Each pixel is independently controlled. The communication method is single-line series communication. It is commonly used in scenes such as music lights and dot matrix screens.
APA102: A digitally controllable full-color LED light strip with a built-in controller and two-wire transmission communication method, which can achieve high-speed and stable data transmission. It is commonly used in stage lighting, exhibition displays and other occasions.
SK6812: An RGB LED light strip with a built-in controller and single-line transmission communication method. It is compatible with WS2812B and is commonly used in DIY decoration, indoor lighting and other scenarios.
TM1914: A digitally controllable full-color LED light strip with a built-in controller and two-wire transmission communication method, which can achieve high-speed and stable data transmission and various lighting effects. It is commonly used in commercial lighting, urban lighting and other fields.
LPD8806: A digitally controllable full-color LED light strip with a built-in controller and two-wire transmission communication method, which can achieve high-speed and stable data transmission and various lighting effects. It is commonly used in automotive lighting, commercial lighting and other occasions.
LED pixel strips
When choosing LED pixel strips, we usually need to configure related accessories for it. Let Zhengbang Optoelectronics introduce it to you.
Accessories for LED pixel strips mainly include controllers, power adapters, connecting cables, etc. The controller is a device that controls the conversion mode, color, brightness and other parameters of LED pixel strips. It is generally divided into two types: manual control and remote control. The power adapter converts AC power from the mains into DC power suitable for the operation of LED pixel strips. Generally, the corresponding power adapter is selected based on the power and length of LED pixel strips. Cables are used to connect LED pixel strips to controllers, power adapters and other equipment. They are generally divided into two types: straight connections and branch connections. The length is also selected according to needs.
In addition, there are some auxiliary accessories, such as fixing buckles, glue, terminals, etc., for installing and fixing LED pixel strips. There may be slight differences in LED pixel strips accessories of different brands and models. When choosing, please choose based on actual needs and equipment parameters.
