1, LED light with the use of chips: chips have domestic and Taiwan chips, as well as import chips (including the United States chip, Japan chip, Germany chip, etc.). Unlike chips, prices vary widely. The most expensive is the United States chip, followed by Japanese chips and German chips, the price of the medium is the Taiwan chip. What chip is used specifically? What kind of effect do you want to achieve?You have to know before you buy.
2, LED Packaging: Resin packaging and silicone encapsulation. The price of the resin package is cheaper, because the cooling performance is slightly worse, the others are the same. Silicone encapsulation of the thermal performance is good, so the price is slightly more expensive than the resin package.
3, LED color consistency: At present there are many packaging factory, large and small add up also have thousands of, of course, there are strength of the points. There are many small packaging factory because there is no separation of light separations, so either color separations, or external hair, so for the quality is difficult to guarantee.No light separation led, the color uniformity is poor, installed in LED lights on the light after the effect is not so good, of course, the price difference is relatively large.
4, LED welding effect: LED lamp assembly is divided into manual welding and machine welding two kinds, manual welding is the use of iron, the most original method for welding. This way out of the product one is ugly appearance (solder joint size inconsistency, flux residue, solder point is not smooth, led packaging was scalded, etc.), the second is not good electrostatic protection measures, many led chips are penetrated, resulting in a micro-light or light when the phenomenon of power. Machine welding is not the same, machine welding is used for welding reflow, not only after the appearance of welding products Beautiful (solder joint size, solder point smooth, helpless flux residue, led packaging intact), and will not appear the chip is the phenomenon of electrostatic burn. At the same time, led position and direction are relatively beautiful. This can be seen directly from the outward appearance.
5, FPC material: FPC pressure-rolled copper and deposited two kinds of copper, copper plate is relatively cheap, more expensive calendering. The plate is easy to fall off when bending, and the copper will not be rolled.The specific use of a material FPC, depends on the purchaser to make their own decisions according to the environment.
