Yintoni umboniso weCOB we-LED?
Umboniso weCOB we-LED umele "iChip-on-Board Light Emitting Diode" umboniso. Luhlobo lwetekhnoloji ye-LED apho iichips ezininzi ze-LED zixhonywe ngokuthe ngqo kwi-substrate ukwenza imodyuli enye okanye uluhlu. Kumboniso we-COB ye-LED, iitshiphusi ze-LED zomntu ngamnye zipakishwe ngokuqinileyo kunye kwaye zigqunywe ngengubo ye-phosphor ekhupha ukukhanya kwimibala eyahlukeneyo.
Yintoni iteknoloji yeCOB?
I-teknoloji ye-COB, emele "i-chip-on-board," yindlela yokufaka izixhobo ze-semiconductor apho ii-chips ezininzi zesekethe ezidibeneyo zifakwe ngokuthe ngqo kwi-substrate okanye ibhodi yesiphaluka. Ezi chips zihlala zipakishwe ngokuqinileyo kunye kwaye zifakwe kwi-resin ezikhuselayo okanye ii-epoxy resins. Kwitekhnoloji ye-COB, iitshiphusi ze-semiconductor zomntu ngamnye zibotshelelwa ngokuthe ngqo kwi-substrate zisebenzisa i-lead bonding okanye i-flip chip bonding techniques. Oku kunyuswa ngokuthe ngqo kuphelisa imfuno yeetshiphusi ezipakishwe ngokuqhelekileyo ezinezindlu ezahlukileyo.
Kwiminyaka yakutshanje, itekhnoloji ye-COB (i-Chip-on-Board) ibone ukuqhubela phambili kunye nezinto ezintsha, eziqhutywa yimfuno yezixhobo zombane ezincinci, ezisebenzayo, kunye nezisebenza kakhulu.

Uyilo lokuguquguquka | Ukuguquguquka okulinganiselweyo ekuphumezeni iimilo eziqhelekileyo | Ukuba bhetyebhetye ngakumbi kuyilo olugobileyo okanye olungaqhelekanga |
1. Xa kuthelekiswa nobuchwepheshe be-SMD, iteknoloji ye-COB ivumela umgangatho ophezulu wokudibanisa ngokudibanisa i-chip ye-LED ngokuthe ngqo kwi-substrate. Oku kuxinana kuphezulu kubangela imiboniso enamanqanaba aphezulu okuqaqamba kunye nolawulo olungcono lwe-thermal. Nge-COB, ii-chips ze-LED ziboshwe ngokuthe ngqo kwi-substrate, eququzelela ukutshatyalaliswa kobushushu obusebenzayo. Oku kuthetha ukuba ukuthembeka kunye nobomi bemiboniso ye-COB buphuculwe, ngokukodwa kwizicelo ezikhanyayo eziphezulu apho ulawulo lwe-thermal lubaluleke kakhulu.
2. Ngenxa yokwakhiwa kwazo, ii-COB LEDs zithembeke ngakumbi kune-SMD LEDs. I-COB ineengongoma ezimbalwa zokungaphumeleli kune-SMD, apho i-chip nganye ye-LED ifakwe ngabanye. Ukudityaniswa ngokuthe ngqo kwee-chips ze-LED kwitekhnoloji ye-COB kuphelisa izinto zokufaka i-encapsulation kwii-SMD ze-LED, ukunciphisa umngcipheko wokuthotywa kwexesha. Ngenxa yoko, iziboniso ze-COB zinokungaphumeleli okumbalwa kwe-LED kunye nokuthembeka okungaphezulu kokusebenza okuqhubekayo kwiindawo ezinzima.
3. Itekhnoloji ye-COB ibonelela ngeenzuzo zeendleko kwithekhnoloji ye-SMD, ngakumbi kwizicelo zokukhanya okuphezulu. Ngokuphelisa imfuno yokupakishwa komntu ngamnye kunye nokunciphisa ubunzima bokuvelisa, iziboniso ze-COB zineendleko eziphezulu zokuvelisa. Inkqubo yokudibanisa ngokuthe ngqo kwitekhnoloji ye-COB yenza lula inkqubo yokuvelisa kunye nokunciphisa ukusetyenziswa kwezinto eziphathekayo, ngaloo ndlela yehlisa iindleko zokuvelisa ngokubanzi.
4Umboniso we-COB we-LEDinokusetyenziswa ngokuthembekileyo nangokuzinzileyo kwiimeko ezahlukeneyo ezinzima.
