LED lights on the market with price disparities affect the LED lights with the main price factors also have a variety of factors, consumers in the purchase, also is not just distinguish from the price of the product is good or bad. Take waterproof, waterproof products than non-waterproof the price is high, home, can choose a non-waterproof LED lights with, not to say that the LED must be your will be able to power saving, you can use long; to look at where we have to use; used to do anything of. Therefore, the right product is the best choice.
The impact of LED lights with the price of the main factors: LED lamp with a price mainly depends on the materials and production processes, such as the use of LED chips, LED glue, LED color LED welding process.
1, the LED lights with the chip: The chip domestic and Taiwanese chip, as well as imports of chips (American chips, Japanese chip, Germany, chips, etc.). Chip, the price difference. Currently the most expensive U.S. chip, followed by the Japanese chips and German chip, and affordable chips.
2, the LED package: points packaging resin and silicone encapsulation. The resin package price should be cheaper, because the thermal performance is a bit weak, others are. The thermal performance of the silicone encapsulated, slightly more expensive than the price of resin package.
LED color consistency: At present, there are a lot of packaging plants, large and small, add up to thousands, of course, the strength of the strong and weak points. There are many small package plants Spectrophotometer machine, either, regardless of the light color separation, or outward, so that for the quality it is difficult to ensure. Without spectrophotocolorimeter led color consistency is poor, installed in the light of the led lights to bring the effect is not so good, of course, the price difference will be relatively large.
4, led the effect of welding: LED lights with the assembly manual welding and machine welding two kinds, hand soldering with a soldering iron, using the most primitive way to carry out welding. Such practices out the product first, ugly appearance (inconsistent solder joint size, flux residue, solder is not smooth, the LED package is ruined, and so on), static protection, many led chip breakdown, lead to power the micro-light or bright. Not the same machine welding machine welding using the reflow soldering, not only welding products (solder joint size, beautiful appearance, smooth solder joints, flux residues, the LED package is intact), and will not chip was burned by the electrostatic a bad phenomenon. At the same time, the location and direction of the LED are more beautiful. This can be seen directly from the appearance.
5, the material of the FPC: FPC sub-rolled copper and copper two relatively cheap, Bonded, rolled copper is more expensive. Bonded Copper pads come off easily when bending, rolling copper does not. Specific FPC of what kind of material depends on buyers to make a decision based on the use of the environment.
, FPC, with or without environmental certification, UL certification? LED whether the patent. After authentication and patented, the price is more expensive, not cheap.
7, the brightness of the LED: different brightness of the LED price, normal brightness and bright LED price difference between the Therefore, the time of procurement must clearly know that they need is what kind of brightness, so as to accurately position their products.
LED color: different colors, the price is not the same. White, green color and the color separation more difficult, so the price is higher than the price of other colors; red, yellow, and blue color color separation is easier, and better consistency, so the price is slightly cheaper. Special colors such as purple, brown, due to reasons of color, the price is the most expensive.
9, the size of the LED: LED of different sizes, different prices. Such as the 0603 LED and 1210 (3528), the LED, the price difference is relatively large; 1210 and 5050 specifications of the LED price difference of a higher level.
