LED light bar because of its high brightness, energy consumption is small, more should be to the building decoration, advertising light boxes, jewelry display and other equipment often bright, but customized LED lights when you need to consider what aspects?
1, look at solder joints. The regular LED light strip manufacturer produces LED light strip, which is produced by SMT paster process and by solder paste and reflow soldering process. Therefore, the solder joint on the LED light strip is smoother and the solder flux is not much, and the solder joint extends from the FPC pad to the LED electrode in an arc shape. However, the solder joints of the LED solder strip are uneven, which often appear as a dot to weld the weld, and there are different degrees of tin tip, which is a typical phenomenon of manual welding.
2, look at the quality of FPC. FPC is divided into two kinds of copper and rolled copper, copper foil is protruding out of the punch, careful look, can be seen from the welding pad and FPC connection. The rolled copper is closely connected with 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. When the temperature is too high, it will cause the pad to fall off.
3, look at the LED strip surface cleanliness. If the LED strip produced by SMT process, its surface cleanliness is very good, can not see what impurities and stains. However, if the hand welding process of the cottage version of the LED strip, no matter how to clean its surface, there will be traces of stains and cleaning, and at the FPC surface there will be soldering flux and tin residue.
4. Look at the packing. Regular LED light strip will be installed with anti-static coil tray, generally 5 meters roll or 10 meters roll, and then use anti-static anti-static packaging bag seal. The cottage version of the LED light strip will be due to cost savings, the use of recycled reel, and then there is no anti-static moisture-proof packaging bags, a careful look at the reel can see the appearance of cleaning labels left traces and strokes
LED lamp 5, compliance will be in the packaging box with instructions and lamp specifications, also equipped with LED lamp connector or card holder; and the LED lamp box version of a copycat is not these accessories, because some manufacturers still can be saved.
Learn the method of the six judgment of LED light quality, all quality LED light can't escape your eye.
