Waa maxay bandhigga COB LED?

Bandhiga COB LED wuxuu u taagan yahay bandhiga "Chip-on-Board Light Emitting Diode". Waa nooc ka mid ah tignoolajiyada LED-ka kaas oo jajabyo badan oo LED ah si toos ah loogu dhejiyo substrate si ay u sameeyaan hal module ama array. Muqaal COB LED ah, chips-ka LED-ga gaarka ah ayaa si adag la isugu soo wada ururiyey oo lagu daboolay daahan fosfoor ah oo iftiimiya iftiin midabyo kala duwan leh.

Waa maxay tignoolajiyada COB?

Tiknoolajiyada COB, oo u taagan "chip-on-board", waa hab lagu soo koobo qalabka semiconductor kaas oo jajabyo badan oo isku dhafan oo isku dhafan ay si toos ah ugu dhejiyaan substrate ama guddiga wareegga. Chips-yadan sida caadiga ah si adag ayaa la isugu geeyaa waxaana lagu daboolaa resins ilaaliya ama resins epoxy. Tignoolajiyada COB, chips semiconductor shaqsi ayaa caadi ahaan si toos ah ugu xidhan substrate-ka iyadoo la adeegsanayo isku xidhka rasaasta ama farsamooyinka isku xidhka chip chip. Kordhinta tooska ah waxay meesha ka saaraysaa baahida loo qabo chips baakadaysan oo leh guryo gaar ah.

Sanadihii ugu dambeeyay, tignoolajiyada COB (Chip-on-Board) waxay aragtay horumarro iyo hal-abuuro dhowr ah, taasoo ay horseedday baahida loo qabo aaladaha elektiroonigga ah ee yaryar, waxtarka badan iyo waxqabadka sare leh.

SMD vs. Tiknoolajiyada Baakadaha COB

1. Marka la barbardhigo tignoolajiyada SMD, tignoolajiyada COB waxay u oggolaaneysaa heer sare oo is-dhexgal ah iyada oo la isku dhejinayo chip LED si toos ah substrate-ka. Cufnaantan sare waxay keentaa bandhigyo leh heerar dhalaal sare iyo maarayn kulayl oo wanaagsan. Iyadoo COB, chips-yada LED waxay si toos ah ugu xidhan yihiin substrate-ka, taas oo sahlaysa kala daadinta kulaylka waxtarka leh. Tani waxay ka dhigan tahay in isku halaynta iyo cimriga COB bandhigyada la hagaajiyay, gaar ahaan codsiyada dhalaalka sare halkaasoo maaraynta kulaylku ay muhiim tahay.

2. Sababo la xiriira dhismahooda, COB LEDs ayaa si dabiici ah loogu kalsoon yahay marka loo eego SMD LEDs. COB waxay leedahay dhibco ka yar guuldarada marka loo eego SMD, halkaasoo chip kasta oo LED si gaar ah loogu duubay. Isku-xidhka tooska ah ee chips-ka LED-ka ee tignoolajiyada COB waxay meesha ka saaraysaa walxaha ku-xidhka SMD LED-yada, yaraynta khatarta nabaad-guurka waqti ka dib. Natiijo ahaan, bandhigyada COB waxay leeyihiin guuldarrooyinka LED-yada oo yar iyo isku hallaynta guud ee hawlgalka joogtada ah ee jawiga adag.

3. Tiknoolajiyada COB waxay bixisaa faa'iidooyin kharash ah oo ka sarreeya tignoolajiyada SMD, gaar ahaan codsiyada iftiinka sare. Iyadoo la baabi'inayo baahida baakadaha shakhsi ahaaneed iyo yaraynta kakanaanta wax-soo-saarka, bandhigyada COB ayaa ah kuwo kharash-ool ah si loo soo saaro. Habka isku xidhka tooska ah ee tignoolajiyada COB waxay fududaynaysaa habka wax soo saarka waxayna yaraynaysaa isticmaalka alaabta, taas oo hoos u dhigaysa qiimaha guud ee wax soo saarka.

4. Waxaa intaa dheer, iyada oo ay ka sarreeyaan biyuhu, ilaalinta boodhka iyo ka hortagga isku dhaca.COB LED bandhigaywaxaa lagu dabaqi karaa si la isku halleyn karo oo deggen deegaanno kala duwan oo qallafsan.

Khasaaraha COB LED bandhigay

Dabcan waa inaan ka hadalnaa faa'iido darrada shaashadaha COB sidoo kale.

Qiimaha Dayactirka: Dhismaha gaarka ah ee COB LED bandhigyada awgeed, dayactirkoodu waxa uu u baahan karaa aqoon gaar ah ama tababar. Si ka duwan bandhigyada SMD halkaasoo qaybaha LED-ka ee gaarka ah si fudud loo beddeli karo, bandhigyada COB waxay inta badan u baahan yihiin qalab gaar ah iyo khibrad si loo dayactiro, taas oo keeni karta wakhti dheer oo hoos u dhac ah inta lagu jiro dayactirka ama dayactirka.

Kakanaanta Habaynta: Marka la barbar dhigo teknoolojiyadda bandhigga kale, bandhigyada COB LED waxay soo bandhigi karaan caqabado qaar marka ay timaaddo habaynta. Gaaritaanka shuruudaha naqshadaynta gaarka ah ama qaabaynta gaarka ah waxay u baahan kartaa shaqo injineernimo dheeraad ah ama habayn, taas oo wax yar dheerayn karta wakhtiga mashruuca ama kordhin karta kharashyada.

Waa maxay sababta ay u dooratay RTLED's COB LED Display?
