LED lights with considerations and parameters of choose and buy

Now LED lights belt is one of indispensable to home lighting products, need to pay attention to when buy 6 elements. Leds with low because the threshold of the production, there are many factories and mills have the project, lead to the LED lamp and evil people mixed up with the market, the production of the product quality is uneven. Without the knowledge and experience are easy to be cheated to buy inferior lamp tape. But experienced people still have a way to identify, formal manufacturers of LED lights belt and shanzhai LED lamp belt (i.e. all by manual work produced in the rental products) is to be able to visually one soon.

Let’s talk about how you with eyes to identify the quality of the LED lamp with good or bad:

1, the solder joints. Regular LED lamp belt manufacturer of LED lights is to use SMT process, with solder paste and reflow soldering process. Therefore, leds solder joints of the belt is smooth and solder amount not much, solder joint circular arc shaped from the FPC welding plate electrode to LED in extension. Amount of solder solder and shanzhai leds with uneven, is one more dot encase leg, will have different degree of icicles appears at the same time, this is a typical phenomenon of manual welding.

2, see FPC quality. FPC divide into two kinds, apply copper and rolling of copper coated copper copper foil is out, scan it can see it from the joint of welded plate and FPC. And rolling of copper is close and FPC is an organic whole repeatedly, can be arbitrarily bent but there will be no solder falls off phenomenon. Apply the coin will appear if there is excessive bending welding plate fall off, repair when the temperature too high can cause pads fall off.

3, look at the LED lamp belt surface cleanliness. If the LED lamp belt of the SMT process, its surface cleanliness is very good, can’t see any impurities and stain. But if use hand welding production of LED lights LED, no matter how the surface cleaning, will remain with traces of the stain and cleaning, and will help in FPC surface residual flux and tin slag.

4, see packaging. Regular LED lamp belt will use anti-static coil disc packaging, usually 5 meters a roll or 10 meters a roll, and then use anti-static moisture-proof packaging seal again outside. But shanzhai will LED lamp belt because of cost savings, and use recycled coil plate, then no anti-static moisture-proof packaging bags, see coil plate can see appearance with clear label and tracks when cut.

5, read labels. Regular LED lamp belt bags will be printed labels and coil plate, rather than the printed label. The shanzhai tags are printed, at the same time, do not have a unified specifications and parameters.

6, see the attachment. Regular LED lights inside the belt will be included in the enclosed instructions and lamp specification, at the same time also can equipped with leds with connector or booth; The shanzhai leds with cartons would not have these attachments, because some manufacturer, after all, still can save a province.
