Drive control is divided into two categories:
 
CC=constant current control, constant current control is subdivided into: external constant current power supply drive control/precision electronic components constant current drive.
 
①: The external constant current power supply drive control means that the power supply and various electronic components + constant current IC are integrated to drive the light board (the light board only has LED light source, without any electronic components).
 
②: The constant current drive of precision electronic components is the integration of light board + constant current IC + LED light source.
 
③: CV=constant voltage control is composed of light board + LED light source + current limiting resistor.
 
2: RGB colorful
 
RGB light strip means that each LED lamp bead is composed of (R) red, (G) green, (B) blue three chips, they can emit (R) red, (G) green, (B) blue, etc. separately The three monochromatic lights can also be composed of two colors of mixed light RG (yellow light), RB (purple light), and GB (cyan-yellow light). At the same time, three chips can emit light together to form a white light. Commonly known as "Colorful".

3: Symphony
 
①: Symphony strips are divided into two types of DMX/SPI control signals; DMX512 is a parallel signal. Its advantage is that the signal of the current pixel is interrupted or damaged, and it does not affect the subsequent signal transmission. The disadvantage is a control port. If only 170 pixels can be connected for expansion, it can control up to 512 pixels; SPI is a serial signal; its advantage is that one control port can be connected to 1024/2048 pixels. The disadvantage is that when a pixel signal is interrupted or damaged, the signal is It cannot be transferred to the next pixel, and it will not work normally later.

②: DMX512 is divided into single-line/double-line differential signal control. There are four lines for a single signal, such as: VCC (+) PI A/D+ GND (-); the signal line is represented by the letter A/(D+), write address The line is represented by the letter PI; there are five lines for dual signals, such as: VCC (+) PI A/D+ B/(D-) GND (-); the signal line uses the letter A/(D+) data positive and B/( D-) The data is indicated by the negative pole, and the address line is indicated by the letter PI.
 
③: SPI control signal is divided into single wire and dual wire, single wire has three wires: VCC (+) DAT (data wire) GND (-); double wire is divided into VCC (+) DAT (data wire) CLK (clock wire) GND (-) Resumable transmission with breakpoint: VCC (+) DAT1 (main data line) DAT2 (auxiliary data line) GND (-); the advantage of resumable transmission is that when a pixel signal is interrupted or damaged, it will not affect the following Pixels work normally, but when two adjacent pixels interrupt the signal at the same time, there is no way to transmit the signal later, and it cannot work normally.

Analyze the structure of LED flat lights 2020-08-20 12:34:00
At present, LED panel lights are more and more widely used in indoor lighting, whether it is hotels, conference rooms, factories or offices, commercial use, residential or public facilities, schools, hospitals, as long as there are places that involve energy saving or require high color rendering Most of them have used LED flat lights to replace traditional fluorescent lamps. On the one hand, LED flat lights play a role in energy saving and environmental protection, and on the other hand they create a good lighting atmosphere. So what does its internal structure look like? Generally speaking, we divide an LED panel light into seven components. Let’s take a closer look at these seven components!
What are the reasons why the LED light bar does not light up during use? 2019-10-17 12:30:00
With the continuous development of society, ordinary people are becoming more and more aware of environmental protection and energy saving, so the demand and quality requirements for LED lighting products are getting higher and higher. With the popularization of LED light bars, LED linear lights, LED panel lights and other lighting products, LED light strips and LED light bars have been widely used in furniture, automobiles, advertising, lighting, ships and other industries.
What are the precautions for the maintenance and installation of the LED flexible light bar? 2019-05-07 12:28:00
The LED flexible light bar has a service life of 30,000 to 50,000 hours in normal use, so it is favored by public users. But any electronic product cannot rule out individual cases of poor electrical properties. Therefore, netizens sometimes say that the flexible LED light bar in their home is not bright, and it is convenient for everyone to troubleshoot and solve the problem after a problem. Here are a few simple ways to repair LED flexible light strips, so that similar problems can be solved quickly in the future.
What is the difference between 2835 flexible light bar and 3528 light? 2018-11-09 12:20:00
The LED light strip refers to the LED light bead welded on the strip-shaped flexible circuit board with SMT processing technology, and then connected to the power supply to emit light. It is named because it is shaped like a light strip when it emits light.
How to distinguish the quality of LED linear lights? 2017-09-12 12:18:00
There are a wide variety of LED linear lights. Many manufacturers admire the quality, low price, long life, etc. of their own linear lights. There are also some high-priced "brand goods". How do we distinguish the quality of linear lights?
How to choose LED downlight, what are the precautions 2020-08-20 12:15:00
There are so many types of LED downlights. Many consumers don't know how to buy LED downlights and how to distinguish their quality. Indeed, the choice of led downlights has certain skills, and there are some precautions. Next we will take a look.
