How to choose led light belt?
How to choose led light belt?
1, look at the solder joint. The LED strip produced by the regular LED strip manufacturer is produced by the SMT patch process, using solder paste and reflow welding process. Therefore, the solder joint on the LED lamp is smooth and the amount of solder will not be much, and the solder joint is extended from the FPC pad to the LED electrode in an arc shape. The solder joint of the shanzhai version of the LED lamp belt is uneven, more than a dot to cover the welding foot, and there will be different degrees of tin tips, which is a typical phenomenon of manual welding.
2, look at the FPC quality. FPC is divided into two kinds of copper and calendered copper, the copper foil of the copper plate is protruding, and it can be seen from the connection between the pad and FPC. The rolled copper is closely connected with the FPC, and can be bent arbitrarily without the phenomenon of pad falling off. If the copper plate is bent too much, the pad will fall off, and the high temperature during maintenance will also cause the pad to fall off.
3, look at the cleanliness of the surface of the LED lamp. If the LED strip produced by the SMT process is used, the cleanliness of the surface is very good, and you can't see any impurities and stains. However, if the shanzhai version of the LED lamp belt produced by the hand welding process is used, no matter how the surface is cleaned, there will be stains and cleaning traces, and the flux and tin residue will be left on the surface of the FPC.
4. Look at the packaging. The regular LED light belt will be packed with anti-static coil tray, generally 5 meters in a roll or 10 meters in a roll, and then the outside is sealed with an anti-static moisture-proof bag. The copycat version of the LED light belt will use a recycling coil because of cost savings, and then there is no anti-static moisture-proof bag, carefully look at the coil tray can see the appearance of the marks and scratches left when the label is removed.
5. Look at the label. The regular LED light belt packaging bag and coil tray will have a printed label, rather than a printed label. The label of the cottage version is printed, and the specifications and parameters are not uniform.
6. See the attachment. The regular LED light belt will be attached in the packaging box with instructions and specifications of the light belt, and will also be equipped with LED light connector or card holder; The copycat version of the LED light belt packaging box does not have these accessories, because some manufacturers can save after all.

What should I pay attention to when buying LED lighting
1, the brightness requirements for different occasions and different products on the LED brightness requirements are also different. For example, if LED jewelry counter lights are placed in some large shopping malls, we will have a higher brightness to be attractive, and the same decorative role is also divided into LED spotlights and LED seven color lights and other different products.
2, anti-static capacity: anti-static capacity of strong anti-static LED, long life, but the price will be higher. Generally, antistatic is better than 700V.
3, the wavelength and color temperature of the same LED, the color will be consistent, this large number of combined lamps are particularly important. Do not produce too much color difference inside the same lamp.
4, leakage current is the LED reverse conduction of the current, we recommend the use of small leakage current LED products.
5, waterproof ability, for outdoor and indoor LED lighting requirements are different.
6, LED lighting Angle has a great impact on LED lamps, and the requirements for different lamps are great, like LED fluorescent lamps, we recommend using 140-170 degrees. We won't explain the rest in detail here.
7, LED chip determines the LED core quality, LED chip brands are many, there are foreign brands (such as CREE, Japan, etc.), there are also China Taiwan (such as gallium, wafer, etc.). The prices of different brands vary greatly.
8, the size of the LED chip also determines the quality and brightness of the LED, we also try to choose a larger chip when choosing, but the price is also different.
