Big power LED

Big power LED drives technical breakthrough to design
Last year, the "ten cities were ten thousand" model engineering didn't be like anticipant of brought a plenteous result so, on the contrary was the weakness that this kind of big power LED illuminates be adequately exposed:LED drives the power credibility to differ very much and has fever Gao, driving of a lot of LEDs the power is burned bad, among them a lot of all cause because the unattractive outer circle small spare part is bad to drop whole drive electric circuit summer reduces weightexpiration."Because LED drives an electric circuit efficiency low cause environment temperature Gao, a lot of spare parts canning not holding against so high heat is burned down.I once saw a burned-out spare part for our customer as well, what to have was an only small triode transistor, diode to burn down, and the whole power collapsed."The Texas Instruments high performance imitates product business to expand the explanation way of manager, Liu Xue Chao, , "'s looking is a small problem, but LED the whole environment temperature is very high, 70% calorieses are to pass to spread hot slice of loose, spreading the hot slice of behind drives the power, the temperature is very high, very difficult control."So, the industry makes great effort now the target is to promote an efficiency and lower a Man degree and promote an integration degree, decrease dollar spare part amount, and an as far as possible use a dependable dollar spare part."For example say that the electricity is a very dependable thing, the electricity is 1,100 in the last years thing used in everyones, not has a source spare part."He adds.water in brief fix

Aim at this target, the TI released formally this year new LED drives structure-double maximum amount string the LLC Tuo plain structure is more opposite than traditional big power(the power is a 250 Ws Ws-300ses) LED drives structure, in that structure the province dropped several expensive high pressure DCs|the DC declines to press a machine and changes to several LLCs Xies that the transformers establish to flap electric circuit and directly carries out Heng to flow, the efficiency significantly promotes to 92% and compares traditional structure to promote 4-5%, the dollar spare part amount also significantly lets up, the credibility promotes, and EMI designs more in briefFlower economy
