Dhinaca baakadaha LED-ka, COB waxay u taagan tahay Chip on Board, tignoolajiyada isha iftiinka dusha isku dhafan oo si toos ah ugu dhejisa chips LED substrate-ka.Ilaha iftiinka LED iyadoo la adeegsanayo tignoolajiyada COB, chip wuxuu si toos ah u daadiyaa kulaylka substrate-ka, isagoo u adkeysanaya cufnaanta kuleylka sare;habayn cufan oo jajab ah, cufnaanta awoodda indhaha ee sare;Cabbirka jirka ee iftiinka leh waa mid yar, oo ku habboon goobta iftiinka ganacsiga oo leh shuruudo adag oo ku saabsan cabbirka isha iftiinka.Marka la barbar dhigo hal xirmo oo jajab ah aaladaha LED, xirmada COB ee jajabyo badan, kala-goysyada alxanka badan, cufnaanta awoodda sare waxay sidoo kale keentay kororka jibbaarada ee adkaanta habka baakadaha.Waxaa la dhihi karaa in isha iftiinka COB ee dhinaca ah ay tahay hormuudka codsiyada nalalka ganacsiga, dhanka kale, sidoo kale waa dahabka taaj ee goobta baakadaha LED.
Shaqada ugu weyn ee iftiinka iftiinka waa iftiinka, LED-ku wuxuu ku darayaa xaddidaadda iftiinka iftiinka - badbaadinta tamarta, sidaas darteed marxaladda koowaad ee horumarinta ilaha iftiinka COB ayaa sidoo kale raadinaysa waxtarka iftiinka, sababtoo ah ilaha iftiinka COB ee isticmaalaya birta Guddiga wareegga-ku-saleysan ama muraayadda dhoobada ah uma fiicna sida gunta qalin-qoriga ah, milicsiga hoose ee lagu sarraysiiyo isugeynta iftiinka ee u dhexeeya jajabyo badan oo nuugista, iftiinka iftiinka COB wuxuu ka hooseeyaa qalabka SMD in ka badan 30%, iyo ka dib Soo bandhigida muraayadda aluminiumka muraayadda si loo xalliyo dhibaatada milicsiga, laakiin nuugista wadajirka ah ee jajabyo badan ayaa weli ka dhigaya iftiinka iftiinka COB ee waxtarka leh inuu ka hooseeyo qalabka kala duwan.Iyada oo chip-ka ka baxsan waxtarka quantum-ka iyo hufnaanta beddelka iftiinka fosfooraska, waxtarka iftiinka iftiinka ee COB wuxuu gaadhay aqbalaadda warshadaha ee "goobta macaan" - 100lm / W, imaatinka bartan macaan marka loo eego aaladaha kala duwan ee soo ururiyay isha iftiinka 2-3 sano ka dib.
Xaalado kala duwan, beddelidda heerkulka midabka isha iftiinka waxay keeni kartaa khibrad iftiin wanaagsan.Marka aysan jirin xaddidaad meel bannaan, way fududahay in la ogaado isbeddelka heerkulka midabka, ilaa inta qalabka heerkulka midabka sare iyo midka hooseeya ay isku dhafan yihiin oo si gooni ah loo wado, isbeddelka heerkulka midabka ee isha iftiinka COB sidoo kale waa fikrad isku mid ah, chips in Ilaha iftiinka COB waxaa loo qaybiyaa laba kooxood waxaana lagu dahaadhay noocyo kala duwan iyo uruurinta fosfooraska isku dhafan, si ay labada kooxood ee jajabku u soo saaraan heerkul midab kala duwan oo iftiin cad ah.Beddel cabbirka hadda ee labada kooxood ee chips, waxaad ka dhigi kartaa isha iftiinka inuu sii daayo heerkulka midabka kala duwan ee iftiinka cad.cabbirka yar ee isha iftiinka COB, ka dib nalka ma arki karo laba heerkul midab kala duwan oo ka mid ah barta iftiimaysa, laakiin dusha iftiin-bixiya isku mid ah, taas oo ah faa'iidada ilaha iftiinka COB, laakiin cabbirka yar, laakiin sidoo kale in ay wax soo saarka isku dhafka midabka COB iftiinka ayaa sababay jahawareer badan.Sannado badan oo sahaminta ka dib, qaabab kala duwan oo jajab ah, dadku waxay ikhtiraaceen oo hagaajiyeen dhowr teknooloji sida daabacaadda, buufinta, iyo chips-ka fluorescent si loo gaaro domain go'an iyo daahan tirada noocyada kala duwan ee fosfooraska ee ilaha iftiinka COB.
Noocyada iyo saamiga labada nooc ee xabagta heerkulka midabka midabka ee midabka-habaynta isha iftiinka COB ayaa la hagaajiyay si loo gaaro tusmooyin muuqda oo muuqda iyo waxtarka sare ee iftiinka isbeddelka midabka oo dhan.Jaantuska 2 waxa uu muujinayaa qalooca midabka sare iyo kan hoose ee isha iftiinka COB ee midab beddela ee uu bixiyo LightSense Semiconductor.Fosfoorka ishan iftiinka ah ayaa la hagaajiyay si tusmada samaynta midabku ay gaadho in ka badan 95 heerkul kasta oo midab ah inta lagu jiro habka isbeddelka midabka ee 3000-6000K, iyo index R9, oo ah mid walaac weyn leh, ayaa ka weyn 80.
Isku hagaajinta heerkulka midabku waxay balaarinaysaa goobta codsiga ee isha iftiinka COB, laakiin midabka laga helay jaantuska gamut midabka wuxuu kaliya ka soo muuqan karaa midabada heerkulka midabka sare iyo mid hooseeya ee xariiqda dhibcaha.Dhinaca iftiinka ganacsiga, isticmaalka isku-duwayaasha midabada kala duwan ee isha iftiinka, waxaad muujin kartaa saameynta muuqaalka midabada kala duwan ee alaabta si loo daboolo baahiyaha bilicda ee dadka, laga soo bilaabo aragtidan, kaliya hagaajinta heerkulka midabka ama kuma filna, in kiiskan, oo leh awoodda lagu hagaajinayo gamut midabka ee isha iftiinka COB ayaa dhashay.
