How LED Strip Light with the quality of identification?


1, a flexible LED strip: This type of LED Strip Light is done using FPC board assembly, assembled with SMD LED, the thickness of the product is only the thickness of a coin, does not occupy space; common specifications are 30cm long 18 pcs LED, 24 pcs LED and 50cm long; 15 LED, 24 颗 LED, 30 pcs LED and so on. There 60cm, 80cm and so on, different users have different specifications. And can be arbitrarily cut to be any extension of the light-emitting unaffected. The FPC soft material, can be bent, folded, winding, three-dimensional space can move freely and stretch without breaking. Suitable for irregular place and narrow space of places, but also because any possible bending and winding, suitable for any combination of a variety of patterns in advertising decoration.


2, LED light bar is made with hard-board PCB circuit board assembly, LED SMD LED helpful for assembly, but also useful for assembly-line LED, depending on different needs and different elements. Advantages light bar is relatively easily fixed, processing and installation are more convenient; shortcomings can not be bent, not suitable for irregular place. SMD LED light bar with has 18 LED, 24 颗 LED, 30 颗 LED, 36 颗 LED, 40 pcs LED, etc. Good variety of specifications; with line LED have 18, 24, 36, 48 different specifications, also has a positive side, the side-emitting light bar, also known as the Great Wall.

How to choose LED Strip Light?


It recommended that consumers in the purchase of LED Strip Light, the first to distinguish it in the end is the best lights with flexible or rigid strip products, to know the different types of lamps with a product, its quality is not the same, not the same length, soft light of not Like using the installation environment is not the same, it advised consumers to better select some regular brands for product purchase more assured.


Look at packaging. Regular LED Strip Light will use anti-static packaging roll tray, usually 5 m or 10 m roll of a roll, and then out again with anti-static bag moisture-proof seal. The cottage version of LED Strip Light because of the cost savings, while the use of recycled roll tray, then there is no anti-static moisture-proof bags, look carefully roll tray can see the appearance of a clear label when traces and scratches.

Look at the label. Regular LED Strip Light with bags and roll above the disk will have a printed label instead of printing labels. The cottage version of the label is printed, as well as specifications and parameters are not unified.

see Attachment. Regular LED Strip Light will be accompanied by instructions in the box and inside lights with specifications, while also equipped with LED Strip Light with a connector or cartridge; and cottage version of the LED Strip Light with these attachments is not in the box, because they could save the province.

Look joints. LED Strip Light with LED Strip Light with regular production is manufactured using SMT chip technology, solder paste and reflow process of production. Therefore, LED Strip Light bring smoother solder joints and solder amount is not much, to the LED pads arcuate electrode extends from the FPC pad place. The amount of solder joints cottage version of LED Strip Light with uneven, mostly a dot wrap welding foot, and have varying degrees of icicles appear, which is typical of manual welding.

Look FPC quality. FPC sub-two copper and rolled copper, copper-clad copper foil is projecting, and then look at the connection from the pad and see the FPC. And rolled copper FPC is close and connected as a whole can be bent and will not appear pad off phenomenon. If there will be too much bent Bonded Copper pad off, when the temperature is too high will cause maintenance pad off.


See LED lamp belt surface cleanliness. If the use of SMT technology, the LED Strip Light, surface cleanliness is very good, I do not see any impurities and stains. But if the hand-welding technology, the cottage version of LED Strip Light, no matter how clean the surface, there will be residual traces of dirt and cleaning, while there remains in flux and dross FPC surface.
