Kuhlala kukho inyathelo kwinkqubo ye-R & D, ukuveliswa kwezibane ze-LED, oko kukuthi, uvavanyo lokuguga oluphezulu noluphantsi.Kutheni le nto izibane ze-LED kufuneka zibe phantsi kovavanyo lokuguga oluphezulu noluphantsi?
Ngophuhliso lwetekhnoloji ye-elektroniki, idigri yokudityaniswa konikezelo lwamandla okuqhuba kunye netshiphu ye-LED kwiimveliso zesibane ze-LED ziphezulu kwaye ziphezulu, isakhiwo sinobuqili ngakumbi, inkqubo iya ngakumbi nangakumbi, kwaye inkqubo yokuvelisa inzima ngakumbi nangakumbi. , eya kuvelisa ezinye iziphene kwinkqubo yokuvelisa.Ngexesha lemveliso kunye nokuveliswa, kukho iintlobo ezimbini zeengxaki zomgangatho wemveliso ezibangelwa kuyilo olungenangqiqo, izinto ezikrwada okanye amanyathelo enkqubo:
Udidi lokuqala kukuba iiparitha zokusebenza zeemveliso azikho kumgangatho, kwaye iimveliso eziveliswayo azihambelani neemfuno zokusetyenziswa;
Udidi lwesibini luneziphene ezinokubakho, ezingenakufunyanwa ngeendlela zokuvavanya ngokubanzi, kodwa kufuneka zibonakaliswe ngokuthe ngcembe kwinkqubo yokusetyenziswa, njengongcoliseko lomphezulu, ukungazinzi kwezicubu, i-welding cavity, ukungahambelani kakubi kwe-chip kunye ne-shell shell resistance and so. kwi.
Ngokuqhelekileyo, ezo ziphene zinokuthi zisebenze kuphela (zivezwe) emva kokuba amacandelo asebenze kumandla alinganisiweyo kunye nobushushu obuqhelekileyo bokusebenza malunga neeyure ze-1000.Ngokucacileyo, akukho ngqiqweni ukuvavanya icandelo ngalinye kwiiyure ze-1000, ngoko ke kuyimfuneko ukusebenzisa uxinzelelo lokufudumeza kunye nokuthambekela, njengovavanyo loxinzelelo lwamandla aphezulu, ukukhawulezisa ukuvezwa kwangaphambili kweziphene.Oko kukuthi, ukusebenzisa i-thermal, umbane, oomatshini okanye iintlobo ezahlukeneyo zoxinzelelo lwangaphandle kwizibane, ukulinganisa indawo yokusebenza enzima, ukuphelisa uxinzelelo, i-solvents eshiyekileyo kunye nezinye izinto, ukwenza iimpazamo zivele kwangaphambili, kwaye zenze iimveliso zidlule kwinqanaba lokuqala. Iimpawu zebhafu ezingasebenziyo ngokukhawuleza kwaye ungenise ixesha elithembekileyo elizinzileyo.
Ngokusebenzisa ukuguga okuphezulu, iziphene zamacandelo kunye neengozi ezifihlakeleyo ezikhoyo kwinkqubo yokuvelisa ezifana ne-welding kunye nendibano inokuvezwa kwangaphambili.Emva kokwaluphala, umlinganiselo weparameter unokuqhutyelwa kwiscreen kunye nokuphelisa izinto ezingaphumeleliyo okanye eziguquguqukayo, ukuze kupheliswe ukusilela kwangaphambili kweemveliso ngaphambi kokusetyenziswa okuqhelekileyo kangangoko kunokwenzeka, ukuze kuqinisekiswe ukuba iimveliso ezizisiweyo zinokuma kuvavanyo lwexesha. .
Ngoku zonke iimveliso zombane ziyafuneka ukuhlangabezana novavanyo lwemekobume yokufuma
Uvavanyo lokufuma luqhutywa ngokubanzi ukufumanisa ukuba ngaba kukho iindawo ezibuthathaka kunye namacandelo kuyilo lwemveliso ngokukhawuleza, kwaye ingaba kukho iingxaki zenkqubo okanye iindlela zokungaphumeleli, ukuze kubonelelwe ngereferensi yokuphuculwa koyilo lomgangatho wemveliso.Ukuze kuqinisekiswe ukusebenza kwemveliso, izikhombisi ezahlukeneyo zeqondo lokushisa kunye nomswakama kunye namaxesha athile ziya kusetyenziswa kuvavanyo.Ngeli xesha, uvavanyo kwinqanaba ngalinye kufuneka liphumelele kwaye lihlangabezane neemfuno zokucaciswa.
Ezinye izinto ezilula ze-hygroscopic, ezifana neebhodi zesekethe eziprintiweyo, iiplasitiki ezikhutshiweyo, iinxalenye zokupakisha, njl.njl., ziya kufunxa amanzi ngokulinganayo ngokuthe ngqo kuxinzelelo kunye nexesha elivezwe kumphunga wamanzi.Xa izinto zifunxa amanzi amaninzi, oko kuya kubangela ukwanda, ungcoliseko kunye nesekethe elifutshane, kwaye nkqu umonakalo umsebenzi imveliso, Umzekelo, ukuvuza yangoku kubangelwa phakathi kwezinye iisekethe ezibuthathaka kwaye kukhokelela ukusilela imveliso.Ezinye iintsalela zeekhemikhali zisenokubangela ukudleka okumandundu kweebhodi zeesekethe okanye i-oxidation yomhlaba wesinyithi ngenxa yomphunga wamanzi.Kwezinye iimeko, isiphumo sokufuduka kwe-electron phakathi kwemigca ekufutshane nayo iya kubangelwa ngumphunga wamanzi kunye nokwahlukana kwamandla ombane ukwenza iifilaments ze-dendritic, ezikhokelela ekungazinzini kwenkqubo yemveliso kunye nezinye iingxaki.
Ukuba imveliso ineengxaki ezinjalo, iimvavanyo ezahlukeneyo zokusingqongileyo kufuneka zenziwe ukukhawulezisa ukwenzeka kwezi ndlela zokusilela, ukuze kuqondwe amanqaku anokubakho engxaki yemveliso.
WellwayIlabhoratri yovavanyo inegumbi lobushushu obuLungiselelayo kunye nokufuma, elinokulinganisa utshintsho lobushushu kunye nokufuma kwimimandla eyahlukeneyo unyaka wonke ngolungiselelo lwenkqubo.I-oveni yoMbane yobushushu obungaguqukiyo bomisa i-oveni kunye neTemperature kunye negumbi lokuvavanya ukufuma inokuqhuba uvavanyo lomda kumacandelo e-elektroniki kwizibane ze-LED kwiindawo ezahlukeneyo kwaye ufumane iindawo ezinengxaki yeemveliso.Zama konke okusemandleni ethu ukubonelela abathengi ngeemveliso zesibane ezithembekileyo nezizinzileyo.
