Iziboniso ze-LED ziimveliso zombane.Ngethuba nje ziyimveliso ye-elektroniki, ngokuqinisekileyo ziya kusilela ngexesha lokusetyenziswa.Ngoko ke zeziphi iingcebiso zokulungisa iziboniso ze-LED?
Abahlobo abaye banxibelelana nemiboniso ye-LED bayazi ukuba iziboniso ze-LED zidityaniswe kunye isiqwenga seemodyuli ze-LED.Njengoko kukhankanyiwe ngaphambili, izikrini zokubonisa i-LED ziyimveliso ye-elektroniki, ngoko ke isakhiwo sayo esisisiseko yindawo yokubonisa (indawo yesibane), i-PCB (ibhodi yesekethe), kunye nomgangatho wokulawula (i-IC component surface).
Ukuthetha ngeengcebiso zokulungisa iziboniso ze-LED, makhe sithethe ngeempazamo eziqhelekileyo kuqala.Iimpazamo eziqhelekileyo zibandakanya: "izibane ezifileyo", "izibungu", iibhloko zombala ezilahlekileyo, izikrini ezimnyama ezinqamlekileyo, izikrini ezinkulu ezimnyama, iikhowudi ze-garbled eziyingxenye, njalo njalo.
Ke indlela yokulungisa ezi glitches ziqhelekileyo?Okokuqala, lungiselela izixhobo zokulungisa.Iziqwenga ezihlanu zobuncwane bomsebenzi wokugcinwa komboniso we-LED: i-tweezers, i-hot air gun, i-soldering iron, i-multimeter, ikhadi lokuvavanya.Ezinye izinto ezincedisayo zibandakanya: i-solder paste (i-tin wire), ukukhuthaza i-flux, ucingo lobhedu, iglue, njl.
1. Ingxaki "yokukhanya okufileyo".
"Ukukhanya okufileyo" kwendawo kubhekiselele kwinto yokuba isibane esinye okanye ezininzi kwindawo yesibane somboniso we-LED azikhanyi.Olu hlobo lokungakhanyisi lukwahlula-hlula lube yi-full-time non-lightness and partial color failure.Ngokuqhelekileyo, le meko kukuba isibane ngokwaso sinengxaki.Inoba imanzi okanye itshiphu yeRGB yonakele.Indlela yethu yokulungisa ilula kakhulu, yitshintshe nje ngamaso e-LED anezixhobo zefektri.Izixhobo ezisetyenziswayo zi-tweezers kunye nemipu yomoya oshushu.Emva kokutshintsha izibane zesibane se-LED, sebenzisa Uvavanyo lwekhadi lokuvavanya kwakhona, ukuba akukho ngxaki, ilungiswe.
2. Ingxaki ye "caterpillar".
"I-Caterpillar" sisikweko nje, esibhekiselele kwinto yokuba ibha ende emnyama neqaqambileyo ibonakala kwindawo yesibane xa isiboniso se-LED sisebenza kwaye akukho mthombo wegalelo, kwaye umbala ubomvu kakhulu.Ingcambu yesizathu salo mcimbi kukuvuza kwe-chip yangaphakathi yesibane, okanye isiphaluka esifutshane somgca wetyhubhu ye-IC emva kwesibane, yangaphambili ininzi.Ngokuqhelekileyo, xa oku kusenzeka, kufuneka sisebenzise kuphela umpu womoya oshushu ukuvuthela umoya oshushu ecaleni “kombungu” ovuzayo.Xa ivuthela kwisibane esiyingxaki, ngokuqhelekileyo ilungile, kuba ubushushu bubangela ukuba i-chip yokuvuza yangaphakathi idibaniswe.Ivuliwe, kodwa kusekho iingozi ezifihliweyo.Kufuneka sifumane kuphela i-bead yesibane se-LED evuzayo, kwaye sibuyisele le ntsimbi yesibane efihliweyo ngokwendlela ekhankanywe ngasentla.Ukuba isiphaluka esifutshane setyhubhu yomgca kwicala elingasemva le-IC, kufuneka usebenzise i-multimeter ukulinganisa i-IC pin yesekethe efanelekileyo kwaye uyibuyisele nge-IC entsha.
3. Iibhloko zemibala engaphelelanga azikho
Abahlobo abaqhelana neziboniso ze-LED kufuneka babone olu hlobo lwengxaki, oko kukuthi, isikwere esincinci semibala eyahlukeneyo ibonakala xa umboniso we-LED udlala ngokuqhelekileyo, kwaye isikwere.Le ngxaki ngokubanzi ukuba umbala IC emva ibhloko umbala utshiswe.Isisombululo kukubuyisela i-IC entsha.
4. isikrini esimnyama esingaphelelanga kunye nendawo enkulu yesikrini esimnyama
Ngokuqhelekileyo, isikrini esimnyama sithetha ukuba xa isikrini sokubonisa i-LED sidlala ngokuqhelekileyo, imodyuli enye okanye ngaphezulu kwe-LED ibonisa into yokuba yonke indawo ayikhanyisi, kwaye indawo yeemodyuli ezimbalwa ze-LED ayikhanyanga.Siyibiza ngokuba sisikrini esimnyama.Sibiza iindawo ezininzi.Sisikhusi esikhulu esimnyama.Xa le nto isenzeka, ngokuqhelekileyo siqwalasela umba wamandla kuqala.Ngokubanzi, khangela ukuba isalathisi samandla e-LED sisebenza ngokuqhelekileyo.Ukuba isalathisi samandla e-LED asikhanyisi, ubukhulu becala kungenxa yokuba umbane wonakele.Yitshintshe nje entsha kunye namandla ahambelanayo.Kuya kufuneka kwakhona ujonge ukuba intambo yamandla yemodyuli ye-LED ehambelana nesikrini esimnyama ikhululekile.Kwiimeko ezininzi, ukujija kwakhona intambo kunokusombulula ingxaki yesikrini esimnyama.
5. i-garbled ngokuyinxenye
Ingxaki yeekhowudi zendawo ezigqwethiweyo zinzima ngakumbi.Ibhekisa kwinto engaqhelekanga, engaqhelekanga, kunye neebhloko zombala ezinokuthi ziqhwanyaze kwindawo yendawo xa isikrini se-LED sidlala.Xa olu hlobo lwengxaki lusenzeka, sihlala silungisa ingxaki yoxhulumaniso lomgca wesiginali, unokujonga ukuba intambo ecaba itshisiwe, nokuba intambo yenethiwekhi ikhululekile, njalo njalo.Kwinkqubo yokulondoloza, sifumene ukuba intambo yocingo ye-aluminium-magnesium kulula ukuyitshisa, ngelixa intambo yobhedu ecocekileyo inobomi obude.Ukuba akukho ngxaki ekujongeni lonke uxhulumaniso lwesiginali, ke ukutshintshiselana ngemodyuli eyingxaki ye-LED kunye nemodyuli yokudlala eqhelekileyo ekufutshane, unokugweba ngokusisiseko ukuba kunokwenzeka ukuba imodyuli ye-LED ehambelana nendawo yokudlala engaqhelekanga yonakele, kwaye unobangela woko. umonakalo ikakhulu iingxaki IC., Inkqubo yolondolozo iya kuba nzima ngakumbi.Andizukungena kwiinkcukacha apha.
