How to identify the quality of LED strips? After reading these points, it is no longer difficult to choose the right light strip

Many novices have little understanding of the quality of LED strips when they choose to buy LED strips. In order to avoid detours, here is how to identify the quality of LED strips.

1. Flexible LED light strips: This type of LED light strips use FPC as the assembly circuit board and SMD LED for assembly, so that the thickness of the product is only the thickness of a coin and does not take up space; the general specifications are 30cm long and 18 LEDs, 24 LEDs and 50cm long; 15 LEDs, 24 LEDs, 30 LEDs, etc. There are also 60cm, 80cm, etc., different users have different specifications. And it can be cut at will, and can also be extended at will without affecting the light. The FPC material is soft and can be bent, folded, and rolled at will, and can be moved and stretched freely in three-dimensional space without breaking. It is suitable for use in irregular places and places with small space, and because it can be bent and rolled arbitrarily, it is suitable for any combination of various patterns in advertising decoration.

2. LED hard light strips are assembled with PCB hard boards. LEDs are assembled with SMD LEDs, and they are also assembled with in-line LEDs. Different components are used depending on the needs. The advantage of the hard light bar is that it is easier to fix, and it is more convenient to process and install; the disadvantage is that it cannot be bent at will, and it is not suitable for irregular places. There are 18 LEDs, 24 LEDs, 30 LEDs, 36 LEDs, 40 LEDs and many other specifications for SMD LEDs for hard light bars; 18 LEDs, 24 LEDs, 36 LEDs, 48 LEDs are used for in-line LEDs. And other different specifications, there are front and side, and the side light is also called the Great Wall light bar.

How to choose LED light strips?

It is suggested that when consumers buy LED light strips, they should first distinguish whether they are flexible light strips or rigid light strip products. It is necessary to know that different types of light strip products have different quality, different lengths, and different light softness. The installation environment is also different. It is recommended that consumers choose some regular brand companies to purchase products with more assurance.

1. Look at the packaging. Regular LED strips will be packaged in anti-static reels, usually 5 meters or 10 meters, and then sealed with anti-static moisture-proof packaging bags. The copycat version of the LED light strip will use a recycled reel for cost savings, and then there is no anti-static moisture-proof packaging bag. If you look closely at the reel, you can see the traces and scratches left when the label is removed.

2. Look at the label. Regular LED strip packaging bags and reels will have printed labels instead of printed labels. The label of the copycat version is printed, and the specifications and parameters are not uniform.

3. Look at the attachments. Regular LED light strips will be accompanied by instructions for use and light strip specifications in the packaging box, and will also be equipped with LED light strip connectors or card holders; while the knockoff LED light strip packaging box does not have these accessories, because They are saving if they can.

4. Look at the solder joints. The LED light strips produced by regular LED light strip manufacturers are produced by SMT patch process, solder paste and reflow soldering process. Therefore, the solder joints on the LED strip are relatively smooth and the amount of solder is not much, and the solder joints extend from the FPC pads to the LED electrodes in an arc shape. However, the amount of solder in the solder joints of the copycat LED light strips is not uniform, and there is more than one dot covering the solder feet.

5. Look at the quality of FPC. FPC is divided into two types: copper-clad and rolled copper. The copper foil of the copper-clad plate is protruding. If you look closely, you can see it from the connection between the pad and the FPC. The rolled copper is closely integrated with the FPC, and can be bent arbitrarily without the phenomenon of pad falling off. If the copper-clad plate is bent too much, the pads will fall off, and if the temperature is too high during maintenance, the pads will also fall off.

6. Look at the cleanliness of the surface of the LED strip. If the LED light strip produced by the SMT process is used, the cleanliness of the surface is very good, and no impurities and stains can be seen. However, if the fake LED light strip produced by the hand soldering process is used, no matter how the surface is cleaned, there will remain stains and traces of cleaning, and at the same time, there will be flux and tin slag residues on the surface of the FPC.
