- How to distinguish inferior LED lights: the brightness of LED light beads
The brightness of the light strips made of poor light beads is relatively low, because the quality of the LED light bead luminescence chip determines that the brightness of the LED light beads made is not high. Those chips are all inferior goods of 1-2 cents. After a period of problems, the electricity leaks (dead lights). The characteristics of genuine chips are high brightness and stable performance, but the price will be high.
- How to distinguish inferior LED lights: FPC board quality
FPC boards are divided into double panels and single panels. Needless to say, double panels are definitely better than single panels, mainly reflected in thermal conductivity is much better, and the quality is definitely more stable, the corresponding price is also higher.
- How to distinguish inferior LED lights: cleanliness of solder joints and surfaces
The LED light strips produced by the regular LED light strip manufacturers are produced using the SMT patch process, using solder paste and reflow soldering processes. Therefore, the solder joints on the LED light strip are relatively smooth and the amount of solder is not much. The solder joints extend from the FPC pad to the LED electrode in a circular arc shape. However, the amount of solder in the solder spot of the cottage version of the LED light strip is uneven, and there is more than one round dot to surround the solder foot. At the same time, there will be different degrees of tin tips, which is a typical phenomenon of manual welding. The home is produced by the placement machine. In addition, the cleanliness of the surface of the LED light strip produced by the SMT process is very good, and no impurities and stains can be seen. If the cottage version of the LED light strip produced by hand welding process, no matter how to clean the surface, there will be stains and traces of cleaning.
- How to distinguish inferior LED lights: color temperature difference
Regarding the color temperature difference, due to the fact that the light bead manufacturer debugs the LED chip, there will be some deviations. It is normal for the color temperature difference to exist, but the LED light strips produced by the regular LED light strip manufacturers basically cannot be seen by the naked eye in the same batch. . The color temperature difference of the same batch of inferior manufacturers is obvious.
- How to distinguish inferior LED lights: material
The high-pressure light belt basically uses PVC material, regular manufacturers will use domestic environmental protection materials, and there is basically no taste. Irregular manufacturers use secondary recycled PVC materials, which will have a great plastic smell during production. Low-voltage lights with sleeves, regular manufacturers will use silicone sleeves, PVC sleeves used by irregular manufacturers, from here, the price varies greatly.
- How to distinguish inferior LED lights: packaging
Regular LED strips will be packaged with anti-static coils, usually 5 meters or 10 meters, and then sealed with anti-static and moisture-proof packaging bags. The cottage version of the LED light belt will use a reel reel for cost savings, and then there is no anti-static and moisture-proof packaging bag. Looking closely at the reel can see that there are marks and scratches left when the label is cleared.
