How to choose waterproof led light bar?
1, see solder joint.
LED strip produced by a regular LED strip manufacturer is produced by SMT, solder paste and reflow soldering. Therefore, the solder joint on the LED lamp strip is smooth, and the amount of solder is not large, and the solder joint extends from the FPC pad to the LED electrode in an arc shape. However, the amount of solder in the LED strip solder joint of the cottage version is uneven, most of the solder joints are covered with a point, and there are different degrees of tin tips at the same time, which is a typical manual welding phenomenon.
2. Look at the quality of FPC
FPC is divided into two types: copper clad copper and rolled copper. The copper foil coated with copper is prominent. If you look carefully, you can see it from the connection between the pad and FPC. Calendered copper is closely combined with FPC, which can be bent at will without dropping the pad.
Step 3 clean
If LED strip is produced by SMT process, its surface cleanliness is very good, and no impurities and stains can be seen. However, if it is hand-welded and produced in LED strip, no matter how it is cleaned, there will be stains and traces of cleaning, and there will be flux and tin slag on the FPC surface.
Step 4 look at the packaging
Regular LED strip will be packed with antistatic reels, usually 5 meters or 10 meters, and then the outside will be sealed with antistatic and moisture-proof packaging bags. However, the fake version of LED strip will use recycling reels to save costs, and then there is no anti-static and moisture-proof packaging bag. If you look at the scroll carefully, you can see the marks and scratches left when the label is removed.
Step 5 read the label
Conventional LED strip packaging bags and reels will have printed labels instead of printed labels. The label of the shanzhai version is printed, and the specifications and parameters are not uniform.
Step 6 look at the attachment
Regular LED strip will attach instructions and specifications for the use of light strips in the box, and will also be equipped with LED strip connectors or card holders; These accessories are not available in the fake version of LED strip packaging box, because some manufacturers can save money after all.
What should LED strip lighting pay attention to?
1, different occasions, different products have different requirements for brightness. For example, in some large shopping malls, LED jewelry counter lights should be attractive with high brightness, and different products such as LED spotlights and LED colorful light bars should be used as decorations.
2. Anti-static ability: LED with strong anti-static ability has a long life, but the price will be higher. Generally speaking, the antistatic performance is better than 700 volts. ..
3. LEDs with the same wavelength and color temperature will have the same color. This large-scale combination of lamps is particularly important. The same lamp should not produce too much color difference.
4. The leakage current is the current when the LED conducts electricity reversely. We suggest using LED products with smaller leakage current.
5, waterproof ability, different requirements for outdoor and indoor LED lights.
The above is how to choose the waterproof led light bar introduced by Bian Xiao. What should LED strip lighting pay attention to? We learned about the choice of waterproof led strip. Of course, in order to ensure the lighting quality in the future, I suggest that when you buy, alas, you can choose brand products according to the decoration of our home or the atmosphere you want. Waterproofing is the most important issue when purchasing waterproof led strip, which can't be ignored, because it is directly related to the use of products.
