LED lighting technology after years of development has formed a set of series of products and technology, I do the LED consisting of six years, six years ago without lighting products like this are everywhere, mostly small power lamp bead, then patch lamp is very expensive. 6 years ago and there are several kinds of LED lamp bead categories: 1, the plug-in lamp bead F3, F5, F8, F10. There are many kinds of different according to the light Angle. Later, the price fall directly nobody do, low-cost plug-in lamp beads, wooden Tomlinson is by doing. 2, SMD lamp beads, 0603, 1206, 0805, 3528, 5050. These tiles are very expensive at that time, not now, a few cents, but a few cents, impression most expensive 1206 a white light more than four MAO. At that time, white light do not count, no real use in lighting top. 3, special-shaped light bead piranha, candle light. At that time a lot of people do piranha, piranhas module is used to do, but it is not used, it's too expensive, dosage of module was great, but two years, however, essential to a few cents. Common LED finished product lamp tape at that time, most module also many, very few other fundamental, lamp with 7 colour from one meter 80 yuan dropped to 10 dollars, now a lot of factories do lamp with people to earn the money, and then do in 08 transformation of the tubes, but the lamp fell from 300 yuan to more than 40 yuan, now has 10 a few dollars, visible fight the market, the market in the mess like this today mainly because of the early stage of the big companies didn't follow up. 08, leishi, mitsuo, op, the channels of take in domestic big brands not bothered to do the LED, leishi until 2012 and bdo, cooperation, early didn't own production lamp bead, visible 08 years to 12 years, 4 years small factory to belong to the channel of these big brand can account for all of about the same. Early originally high-power LED lamp bead, at the time of lamp bead brightness is not high, but the stability is the best, I five years ago I did a LED ball steep light, it is lit, not like now, a ball steep light 2. 3 yuan, the light is less than two months. And radiator at that time is very good, very thick, do manual work is also very good, very delicate, switch power supply, power supply is the original do people make, stability and the technology not good now, but the use of material is very good, so use the 5 years all right.
