Farqiga Ilaha Iftiinka COB

Way fiicantahay in la doorto qalabka elektarooniga ah ee kubbadda, sababtoo ah qalabka elektarooniga ah wuxuu leeyahay sifooyin lagu hagaajinayo iftiinka iftiinka iyo nolosha nalka. Waqtigan xaadirka ah, dhammaan ilaha iftiinka fluorescent ee suuqa waa inay lahaadaan ballast si ay u shido. Laga soo bilaabo falanqaynta tirada shaqada chip iyo cufnaanta isku dhafan ee chip, waxaa la ogaaday in baakadaha isku dhafan multi-chip nalka cad nalka LED heerkulka kordho kororka tirada chips isku dhafan. Waxtarka iftiinka iftiinka ayaa hoos u dhacay kororka tirada jajabyada isku dhafan, sidaas darteed tirada jajabyada iyo cufnaanta isku dhafan ayaa sidoo kale ah arrin muhiim ah oo saameyn ku leh codsiga farsamada baakadaha isku dhafan. Buurta Cob “Madolaad buuxda COB →LED ”, Waxaad si toos ah u koobi kartaa chips badan on MCPCB on guddiga daabacaadda biraha ku salaysan, oo si toos ah u kala firdhiso kulaylka dhex substrate si loo badbaadiyo kharashka baakadaha LED, kharashka wax soo saarka engine module, iyo kharashka iftiinka sare. Marka la eego waxqabadka, iyada oo loo marayo naqshad macquul ah iyo microscopy, moduleka Ilaha iftiinka ee COB wuxuu si wax ku ool ah uga fogaan karaa faa'iido darrada iftiinka iyo iftiinka ka jira isku-dhafka kala-soocidda qalabka iftiinka; Waxa kale oo ay si wax ku ool ah u wanaajin kartaa midabka isha iftiinka iyadoo ku daraysa isku-darka jajabka cas ee ku habboon galmada. Doorka isha iftiinka COB waa in uu keeno danab bilow degdeg ah iyo danab deggan isha iftiinka. Waxaa la arki karaa in tayada ballastadu ay si toos ah u go'aamin doonto nolosha iyo iftiinka iftiinka nalka si toos ah. Marka lagu daro mugga, isha iftiinka LED ayaa sidoo kale faa'iido u leh nolol dheer. Tani sidoo kale waa faa'iidada ugu weyn. Xawaaraha dheereeya ee nalka iftiinku waa yarayn, laakiin xawaaruhu waa gaabis. Laga soo bilaabo dhinacyada isticmaalka nalalka kala duwan, ilaha iftiinka COB ayaa inta badan loo isticmaalaa qalabka nalalka gudaha sida nalalka LED-ka, nalalka saqafka LED, iwm. Tirada ugu badan ee hal watt kama badnaan doonto 50W. Ilaha nalalka sare ee isku dhafan ayaa inta badan loo adeegsadaa nalalka waddooyinka iyo nalalka warshadaha sida nalalka waddooyinka cadceedda, nalalka LED, nalalka waddooyinka, LED warshadaha iyo nalalka macdanta. SMD waxay si tartiib tartiib ah u beddeshaa ilaha iftiinka HP. Ilaha iftiinka HP ayaa hadda lagu dabaqaa bannaanka. COB wali waxay leedahay meelo qaar oo u baahan in la hagaajiyo. MCOB hadda laguma dalacsiin heerka hadda jira. Wadashaqeynta si loo bilaabo marka loo eego qaybaha COOBoptical hadda (aluminium ama PMMA alaabta tuulada, iwm.). Waqtigan xaadirka ah, cabbirka isha iftiinka COB si buuxda looma habayn. Marka ilaha iftiinka COB ay yihiin 10,000 saacadood, dhalaalku wuxuu gaari karaa 70% ilaa 80% dhalaalka bilowga ah, iyo isha nalka iftiinka ee caadiga ah ayaa la bedelay laba jeer wakhtigan isticmaalka. Ka dib oo dhan, isha iftiinka dhaqameed wuxuu isticmaali karaa oo keliya 4000 saacadood oo dhalaal ah. Kaliya kala badh dhalaalka bilowga ah ayaa ka yar kala badh xulashada ishan iftiinka LED ee bilaashka ah. Isha iftiinka COB waxaa si fudud loo fahmi karaa inay tahay il koronto oo isku dhafan oo awood sare leh. Aagga bannaanka iyo cabbirka qaabka isha iftiinka waxaa loo qaabayn karaa iyadoo loo eegayo qaabka qaabka sheyga. Sida warshad istaraatiiji ah oo soo koraysa oo ka jirta dalkayga, iftiinka semiconductor. Si kastaba ha noqotee, dhinaca ilaha iftiinka LED-ka ee gaarka ah, sababtoo ah heerka sare ee farsamada, suuqa waxaa ka mid ah shirkadaha ajnabiga ah. Nalalka semiconductor waa kacaan tignoolajiyadeed qarnigan. Marka loo eego qaan-gaarnimada farsamada, wali waa ilmo. Inkasta oo tignoolajiyada iftiinka cad ee awoodda sare leh ay si degdeg ah u horumartay, saddexda nool ee ku nool suuska iftiinka LED-ka, kulaylka, iyo qiimaha ayaa weli ah LEDs. Tiger Tiger, caannimada iyo horumarinta iftiinka. Ilaha iftiinka COB COB (CHIP on Board) waa in lagu hagaajiyo jajabka iyada oo loo marayo xabagta qalinka ee substrate-ka, iyo habka isku xirka korantada ee chip-ka iyo substrate-ka waa la fuliyay.
