Falanqaynta faahfaahsan ee Soosaarayaasha Zhuhai Isha Iftiinka LED iyo Isha Isku-dhafan ee COB

Ilaha iftiinka isku dhafan ee COB iyo ilaha iftiinka LED waa laba nooc oo nalal ah oo caan ku ah warshadaha nalalka maanta. Farqiga u dhexeeya ayaa ah in ilaha iftiinka isku-dhafan ee LED ay guud ahaan isticmaalaan chips-yada awoodda sare leh ee cabbirka weyn ee LED-ka oo leh cabbir weyn oo ka badan 1 watt. Isha iftiinka COB waxay inta badan ku saleysan tahay jajab yar oo LED ah oo ka yar 1 watt, iyo qadar yar oo ilayska COB ah ayaa sidoo kale isticmaali doona chip LED oo awood sare leh oo ka badan 1 watt. Sifooyinkooda guud waxay leeyihiin xoogaa isku mid ah, soosaarayaashuna waxay sameeyaan falanqayn faahfaahsan qof kasta. COB sifooyin isku dhafan oo isha iftiinka ah si ay isugu daraan dhowr ilood oo laydh yar oo LED ah oo ku yaal meel taagan si loo helo ilaha iftiinka si ay u dhexgalaan ilaha iftiinka. Guud ahaan iyada oo la tixraacayo qaabka daboolida Chip on Board, kaas oo badanaa loo yaqaan baakadaha COB, taas oo ah, in si toos ah loo dhigo dhowr chips substrate, ku duub silikoon, resin epoxy ama qalab kale. Jaaluhu waa budada fluorescent. Waqtigan xaadirka ah Dhibaatada ugu weyn ee codsiyada nalalka ayaa ah dhibaatada budada fluorescent ee kacsan iyo gabowga muraayadda. Ilaha iftiinka isku dhafan ee COB ayaa si weyn loogu isticmaalaa goobooyin LED, koobabka iftiinka LED, nalalka LED-ka, nalalka LED-ka, nalalka saqafka LED, alaabada nalka bean bile. Waa mid ka mid ah isbeddellada caadiga ah ee ilaha iftiinka LED-ka. Waxaa si xor ah loo isku dhejin karaa oo la isku dari karaa si loo sameeyo noocyo kala duwan oo nalalka LED ah, taas oo ku habboon isu imaatinka. 2. Kalsooni heer sare ah, ma jiro laambad dhintay, ma jirto tabeelo. 3, Iftiin direyska ah, iftiin jilicsan, dhalaal la'aan, aan dhaawacin indhaha. 4. Tusaha samaynta midabka sare, saamaynta iftiinka sare. 5. Waqtiga xaadirka ah ee caadiga ah, hoos u dhigista ugu yar ayaa la xakameynayaa in ka yar 3% gudaha 1000H. 6. Badbaadsan oo la isku halayn karo, dhammaan waxay shaqeeyaan wax ka hooseeya 50V, si buuxda u tixgeli shahaadada codsiga. 7, ilaalinta deegaanka cagaaran, wasakh la'aan. LED, tamarta sare ee waxtarka leh -saamaynta badbaadinta, ayaa la siiyay cinwaanka iftiinka cagaaran. Marka loo eego falanqaynta alaabada nalalka LED-ka, ilaha iftiinka isku-dhafan ee COB, oo ah xuddunta iftiinka, ayaa had iyo jeer ahaa xudunta horumarka LED. Fahamka ilaha iftiinka isku dhafan ee COB waxaa loo qaybin karaa dhinacyo badan. Guji, ka dibna waferka silikoon si toos ah u dhig dusha sare ee saldhigga, kuleyli si aad u hagaajisid waferka silikoon ilaa saldhigga si adag loo hagaajiyo, ka dibna isticmaal habka alxanka xariirka si aad si toos ah u sameyso xiriirinta korantada ee u dhexeeya wafer silikoon iyo saldhigga. Marka la barbardhigo substrate-ka aluminium dhaqameed, ceramics, ceramics Milicsiga substrate waa mid sarreeya, kaas oo gacan ka geysanaya hagaajinta iftiinka iftiinka. Ceramics waxay leedahay sifooyinka kalsoonida sare, nolosha dheer iyo sifooyinka kale. Balaadhinta kulaylka iyo isku xidhka foosha ee dhoobada ayaa yar. Xitaa jawiga heerkulka sare, dusha sare waa mid siman, taas oo ka caawisa daadinta kulaylka. Way fududahay in la isku keeno, waxaad si toos ah u ururin kartaa substrate dhoobada COB isha iftiinka si toos ah hiitarka iyada oo loo marayo kuleyliyaha. Isku-dhafka kuleyliyaha dhoobada ayaa aad u sarreeya, LED waxay leedahay heerka dayactirka kulaylka ee hogaaminaya warshadaha (95%), iyo ceramics waa insulator. Waxay ka caawisaa alaabta nalalka LED si ay u gudbaan imtixaanada sare ee kala duwan oo ay iska caabin karaan cadaadis sare 4000V ama ka badan. Dooro kuulyada nalalka LED-ka si aad u dooratid saxaraha saxda ah ee tayada sare leh. Qalabka waa la dammaanad qaaday, qiimaha xaddi badanna wuxuu noqon doonaa mid aad u wanaagsan. Ma jiro dhexdhexaadiye kasbanaya faraqa u dhexeeya. Xiaobian waxay ku talinaysaa soo saaraha Zhuhai Isha iftiinka LED iyo Ilaha iftiinka isku dhafan ee COB. Hubi in soosaarayaasha LED ay yihiin kuwo la aamini karo! Tilmaamaha isha iftiinka LED Isha iftiinka LED waa isha iftiinka iftiinka iftiinka (LED), kaas oo leh sifooyinka waxtarka sare iyo nolosha dheer. Ilaha iftiinka LED-ka inta badan waxaa ka mid ah ilaha iftiinka giraanta, ilaha iftiinka xariijinta, ilaha iftiinka-nooca, ilaha iftiinka diidmada, ilaha iftiinka dambe, ilaha iftiinka kookaha ee dibedda, ilaha iftiinka coaxial-qaabeeya, ilaha iftiinka hemispherical, iwm. Iyada oo cilmi-baaris joogto ah oo cilmi-baaris ah oo dadka ah oo ku saabsan qalabka iftiinka semiconductor, horumarka joogtada ah ee habka wax-soo-saarka LED-ka iyo horumarinta iyo codsiga alaabta cusub (kiristaalo nitride iyo budada fluorescent), iftiinka ultra-sare ee iftiinka midabada kala duwan ayaa sameeyay horumar horumarsan, iyo iftiinkooda ayaa la sii daayaa Waxtarka ayaa soo fiicnaaday wax badan, iyo dhammaan midabka qaybta mawjada iftiinka muuqda ayaa la ogaaday marka la eego midabka. Waxa ugu muhiimsan waa muuqaalka ultra-high dhalaalka iftiinka cad ee LED-ka, taas oo ka dhigaysa goobta codsiga LED-ka ee suuqa ilaha iftiinka ee waxtarka sare leh. Qof ayaa mar tilmaamay in iftiinka sare ee LED uu noqon doono mid ka mid ah ikhtiraacyada waaweyn ka dib markii ikhtiraacii aadanaha ay ikhtiraaceen ikhtiraacida nalalka iftiinka. 1. Hufnaanta qiiqa sare, LED waxay hagaajisay waxtarkeeda iftiinka ka dib tobanaan sano oo horumar farsamo ah. Iyo monochromaticity iftiinkeeda iyo spectrum spectrum cidhiidhi ah, shaandhada si toos ah uma soo saari karto iftiin muuqda oo midab leh. 2. Lacagta u yar. 3. Nolosha nolosha, adeegso shucaaca goobta iftiinka elegtarooniga ah, iftiinka fiilo oo si fudud loo gubi karo, weelka kulaylka, yaraynta iftiinka iyo khasaarooyinka kale. Baaxadda nalalka LED-ku waa yar yahay, miisaan fudud, iyo baakadaha resin epoxy waxay u adkeysan karaan saameynta farsamo ee xoogga badan iyo gariirka, ma fududa in la jebiyo. 4. Badbaadada xooggan iyo kalsoonida, kulaylka hooseeya, shucaaca kulaylka ma jiro, ilo iftiin qabow, si ammaan ah ayaa loo taaban karaa: waxay si sax ah u xakameyn kartaa xagasha iftiinka iyo iftiinka, midabka jilicsan, malaha; ma jiro meerkuri, curiye sodium, iwm. waxay khatar gelin kartaa caafimaadka iyo caafimaadka. Qaad. Nidaamka daawaynta yar-yar ee la dhisay ayaa xakameyn kara xoogga iftiinka, hagaajinta habka iftiinka, oo ogaanaya isku-dhafka iftiinka iyo farshaxanka. 5. Waxay ku habboon tahay LED-ka deegaanka ee saaxiibtinimo sida jidh iftiin buuxa leh, caabbinta naxdinta leh, iska caabbinta saameynta ma fududa in la jebiyo, qashinka dib ayaa loo warshadeyn karaa, wasakh ma leh. Mugga isha iftiinku waa mid yar waxaana la isku dari karaa marka la doono. Way fududahay in lagu horumariyo alaabada iftiinka fudud iyo kuwa gaaban iyo kuwa gaaban, taas oo sidoo kale ku habboon rakibidda iyo dayactirka. Kuwa kore waa sifooyinka ilaha iftiinka isku dhafan ee COB. Tilmaamaha isha iftiinka LED si faahfaahsan ayaa loo falanqeeyay. Waxaan aaminsanahay in farqiga u dhexeeya labadan nalal uu sidoo kale fahmayo.
