Mess up! Announced LED packaging links six tricky"

Now LED people, it is more and more will play, and there are a lot of tricks have been played, and the market is really chaotic rebirth ah. 1W 35mil beads you sell 8 hair, ha ha, I better than you, I sell 2 hair. After reading the inside of the tricky, think tank think you can not bear the torment: sell my love, forcing me to leave, and finally know the truth of my tears flow down......

Now the LED market price is multifarious, the quality is uneven, many reasons are in the Chinese market, the product appearance is similar, does not have any patent, therefore the price war has caused the quality to be uneven. Good price good quality we want, but it is difficult to have such a thing on the market.

One from the beginning of 2006, engaged in LED packaging engineering research and technology management work in a number of packaging factory, but has left the LED industry industry engineer LED engineer, will tell you all the tricky about 8 years working in the LED lamp packaging factory to, I hope you have eyes to choose good LED lamp products.

LED lamp is how to do it:

In imitation of lumens high power LED lamp as an example, the solid crystal, welding line, glue dispensing, cover lens and light, packaging and other production processes is made, each link has a different technology, but the technology is not the main raw materials, quality is the main raw material, determines the price, such as 1W 35mil crystal beads, 0.2 yuan, 0.4 yuan, 0.6 yuan, 0.8 yuan, 1 yuan more than the other, their prices are reasonable, not what violence is the selection of the raw material price, do not result in the same. Baoliao Engineer in packaging factory, raw materials and what is seen, do quality packaging factory, garbage packaging factory and so on, which are spent, and the price of their material will now be revealed to you, hoping to help.

LED why the price difference so big:

The wafer 35mil chip as an example. 0.2-0.4 yuan 1W market the Jingyuan 35mil beads (basic is collecting from packaging factory, to light products, in general, is defective) 0.6 yuan of wafer 35mil beads (usually pseudomorphic crystal do), there are 0.8 yuan of wafer 35mil beads (generally more common timber that is not a good thing to do), there are 1 yuan of Jingyuan 35mil beads (general material is relatively good, do quality packaging factory do). Baoliao the packaging factory choose what material, what products tell you (in imitation of lamp lumens with other beads as well).

Solid crystal process tricky: solid crystal chip is fixed on the bracket, the main material used is the stent and the chip, said the chip and the bracket is good or bad.

LED lamp bracket tricky: there are aluminum bracket, bracket, bracket brass copper aluminum frame on the market, the cheapest, 1W imitation lumens at the price of 0.06 yuan, 0.12 yuan in brass, copper in 0.16 yuan. The thermal conductivity of aluminum frame, the brass, copper best (you choose heat very seriously, the power quality is also very seriously, the housing price, the power price is very high, often choose the LED lamp is getting worse, have the order reversed). The lamp 0.4-0.6 yuan on the market is basically made out of aluminum frame, 0.6-0.8 yuan, is the basic support made out of brass, 0.8-1 yuan, is made out of copper stent. Even the copper bracket, silver crossing has 40, 60, 80, 100, and so on, the price is also very different, ranging from $0.18 to $0.13. 0.8 yuan or so is the basic silver to do the cross, the basic value of 1 yuan is more than 80 of the silver cross do. A lot of packaging factory, the commitment bracket is a copper is actually brass or adulterated copper.

LED chip trick: LED chip on the market now to 35 of all kinds of Jingyuan, for example, there are a lot of beads is fake wafer chip do, chip size, appearance and Jingyuan 35 chip structure completely not as like as two peas, but as the light fades and the life will be different. Such as regular epstar chip in 0.35 yuan, which is a high imitation fake Jingyuan Jingyuan in less than 0.2 yuan, the price difference is very big. Many packaging factory for bullying lamps factory do not understand the chip, so the pseudomorphic crystal wafer seriously sales price in about 0.6-0.8 yuan, some also sold 0.9 yuan. Formal high-power chip, also have different grade is good or bad, the chip on the market has project product, regular product, big round, scattered piece. As a brand of 35mil chip, the regular product is 0.35 yuan, if the use of the material to do, the price of 1 yuan or so, with almost the material, the price of 0.8-1 yuan; the project is 0.25 yuan, 0.01 yuan is scattered, wafer is sorting, 0.25 yuan do these basic is 0.4 yuan and 0.8 yuan. LED lamp, LED lamp LED lamp is the core, the core is LED chip, the same is true of the chip, the price difference is very big. We have to open their eyes to see clearly, poor chips of course cheap.

Welding process welding line line is tricky: the chip and bracket with gold link, the raw material is used gold alloy wire is currently on the market, gold two, gold 0.7, and in accordance with the thickness of 0.9, 1, 1.2, alloy wire 1W cost 0.01 yuan, if the gold is 1.2 is 0.07 yuan, a lot of people do 1W, 0.4-0.6 yuan 1W 35mil called crystal beads, alloy wire is basically done; 0.8 yuan 35mil crystal beads, gold is 1 gold, 1 yuan in the 35 crystal beads, 1.2 gold is basically done. Gold has good ductility
