LED lights with buying guide as follows:
1, LED lights with the use of chip: There are domestic and Taiwanese chip chip, as well as imported chips (including the United States chip, Japan chip, Germany, chips, etc.). Different chips, prices vary widely. US chip is currently the most expensive, followed by Japan and Germany chip chip, Taiwan chip affordable. Specifically in what chip? What kind of effect you want to achieve? First idea in mind before purchasing.
2, LED encapsulation: min resin package and silicone encapsulation. Resin package price is cheaper, because thermal performance a bit weak, the other is the same. Good thermal performance silicone encapsulation, so the price is slightly more expensive than the resin encapsulation point.
3, LED color consistency: At present, there are a lot of packaging factory, there are thousands of large and small, add up, of course, also have strong and weak points of strength. There are many small package plant because there is no separation by machine, so regardless of light or color separations, or is outgoing, so it is difficult for quality assurance. Without spectrophotocolorimeter LED, the color consistency is poor, mounted on the rear LED lights bring lit the effect is not so good, of course, the price difference will be relatively large.
4, LED welding effect: LED lamp assembly points with two hand soldering and welding machines, hand soldering iron is used, using the most primitive way unevenly welded, the amount of solder joints, mostly a dot wrap fillet while there will be varying degrees of icicles appear, this is typical of manual welding. This mode of operation out of the product first, ugly appearance (weld size is inconsistent, much flux residue, solder joints is not smooth, LED packages are ruined, etc.), and second, static protection is not good, a lot of LED chip is the breakdown, cause micro-light or no light phenomenon when energized. Welding machine is not the same, the use of SMT chip technology, with solder paste and reflow soldering process of production. Thus, LED lights bring smoother solder joints and solder amount is not much, joints arcuate LED electrodes extend not only beautiful appearance after soldering (solder pads of the same size from the FPC to, smooth solder joints no flux residue, LED packaging intact), and will not appear chip is electrostatically burned phenomenon. Meanwhile, LED position and orientation are more beautiful. This can be seen from the exterior.
5, FPC Material: FPC sub-rolled copper and copper are two, Bonded Copper is cheaper, rolled copper more expensive. Bonded Copper pad off easily when bent, but rolled copper will not. Which specific use of material FPC, depends buyers themselves to make a decision based on the environment.
6, FPC Have been environmental certification, UL certification? LED whether the patents. There are a certified and patented, more expensive, not cheaper prices.
7, LED brightness: different brightness LED price different from ordinary brightness LED price difference and highlighted relatively poor. Therefore, when purchasing must clearly know what they need brightness, so as to accurately position their products.
8, LED colors: different colors, price is not the same. White, green due to the color and color separation more difficult, and therefore expensive than other colors price is higher; red, yellow, blue and other colors spectrophotocolorimeter relatively easy, and consistency is better, so the price is slightly cheaper. Special colors such as purple, brown and other reasons due to the color, the price is the most expensive.
9, LED Size: different size specifications of LED, different prices. Such as LED 0603 and 1210 (ie, 3528) of the LED, the price difference between the larger; the 1210 and 5050 specifications of LED prices will differ by one level.
10, see the cleanliness of the surface of the LED light strip. If using SMT technology, the LED lights, surface cleanliness is very good, I do not see any impurities and stains. But if the hand-welding process to produce copycat version of LED lights, no matter how clean the surface, there will be residual traces of dirt and cleaning, while there remains in flux and dross FPC surface.
11, look at the packaging. Regular LED lights will use anti-static roll disc packaging, usually 5 m or 10 m roll of a roll, and then the outside and then use anti-static moisture-proof bag sealed. The cottage version of the LED lights because of the cost savings, while the use of recycled roll tray, then there is no anti-static moisture-proof bags, look carefully roll pan can see the appearance of a clear label when traces and scratches.
12, look at the label. Regular LED lights 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.
13, see annex. Regular LED lights will be accompanied by instructions for use inside the box and lights with specifications, while also equipped with LED lights with connector or a deck; the cottage version of the LED lights with packing box is not these attachments, because Some manufacturers, after all, could save the province.

What LED lights with installation considerations are
LED lights with mounting PRECAUTIONS: Wiring LED lights with LED lights with generally voltage DC 12V, so need to use switching power supply, the size of the power supply according to the power and the connection length LED lights to be. Wiring monochrome 5050 SMD LED lights to distinguish between positive and negative, in general we provide good welding power plug directly into our offer lamps with power like the above, then all the LED lights with all input power parallel, unified by the total switching power supply. LED lights with mounting PRECAUTIONS: The controller connection LED ticker tape and Symphony of Lights with RGB controller is required to achieve the effect of changing the wiring of the time.
