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.
 
More and more large shopping malls and supermarket buildings are decorated with LED light strips at night, which gives us a brilliant and colorful brilliance, which makes us feel happy while enjoying the beautiful scenery. But sometimes, when the LED light strip has been used for a long time, it will become darker or darker. So what are the reasons why the LED light strip is not bright? I will explain to you today:
 
1. Damaged during transportation: The packaging protection of the LED light bar is imperfect, causing damage to the internal lamp beads during transportation. Or it may appear that the solder joints of the LED light bar have a virtual soldering phenomenon, and the vibration during transportation causes the solder joints to fall off and the light bar does not light up.
 
2. Process defect: LED light bar has a small amount of solder and the solder joints are easy to fall off. Or the solder quality of the LED light bar is not good, and the solder joints of the LED flexible light bar are prone to brittle cracks and fall off during the bending process. The solder resist layer of the light bar circuit board is too thick, and the solder and the circuit board cannot be completely fused together during soldering, which is also a kind of virtual soldering phenomenon.
 
3. Improper installation: The bending angle of the LED light bar is too large during installation, which causes the solder joint of the LED flexible light bar to separate from the copper foil and cause no light. If the product is excessively squeezed during installation, the LED flexible light bar chip will be damaged or the solder joints will deform and fall off and will not light up. Therefore, users are especially reminded not to twist during installation, so as to avoid the solder joints falling off and causing no light.
 
Therefore, the above problems need to be avoided when selecting LED light strips, so as to ensure that the LED light strips have better quality and longer service life.

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 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.
