Determine the price of LED Strip Light nine major factors


      LED Size: different size specifications of the LED prices are different. As 0603 LED 3528 LED(1210 LED) that the price difference between the larger its; while 1210 and 5050 specifications of the LED prices will differ by one level. LED Strip Light purchasing, do not just focus on price. Should be from the following aspects to comprehensive assessment, in order to buy inexpensive LED Strip Light.

        LED Strip Light used in chip: chip has domestic and Taiwan chip and chip imports (including the United States chips, Japanese chip, Germany chips). Different chips, prices vary widely. Currently the most expensive American chips, followed by Japan and Germany, chip chip, the lowest price of the Taiwan chip, thermal performance slightly worse. Specific uses what chip? To what kind of effect? Before you buy first knew it.

        LED package: sub silicone resin encapsulation and packaging. Resin package price should be cheaper. Others are the same. Silicone encapsulated heat dissipation, so the price is slightly more expensive than the resin package that.

        LED color consistency: At present, there are many packaging factory. There are thousands of large and small, add up, of course, the strength of the strong and weak points. There are many small packaging plant because there is no color separation machine, so regardless of light or color separations, or is outward, so that it is difficult for quality assurance. Spectral separation of the LED without its color consistency is poor, bring lit LED Strip light installed in the rear of the effect is not so good, of course, also the price difference is relatively large.

        LED welding effect: LED strip light the assembly of two kinds of hand soldering and welding machines. Hand soldering iron is used, using the most primitive methods for welding. Such practices into the product first appearance of unsightly (spot size is inconsistent Fuzhou LED electronic display) two electrostatic maintenance measures are not good, a lot of the LED chip is the breakdown, resulting in micro-light when powered on or off phenomenon. With reflow soldering machine for welding, soldering machine is not the same. The products not only look beautiful after welding (spot the same size, joints smooth, no flux residue, LED packaging intact) and will not appear burned chip is static phenomenon. Meanwhile, LED position and orientation are more beautiful. This can be seen directly from the appearance.

        FPC Material: FPC sub-rolled copper and copper two kinds. Bonded cheaper, rolled copper expensive. Bonded Copper pads come off easily when bent, and rolled copper will not. Specific use depends on what kind of material FPC sell themselves to make a decision based on the environment.

        FPC whether through environmental certification, UL certification? LED without patents. Not inexpensive. There are certified and patented more expensive.

        LED Brightness: Different brightness LED prices are different. Normal brightness and brightness of the LED price difference compared poor. Therefore, the time of purchase must clearly know what they need brightness, such talent accurate positioning their products.

        LED color: different color. Price is not the same. Red, green color and the color separation as more difficult, so the price is higher than the price of other colors high; red, yellow, blue and other colors spectrophotocolorimeter relatively easy, and the consistency is better, so the price is slightly cheaper. Special colors such as purple, brown and other colors reasons because its price is the most expensive.
