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 ngokusisigxina olungakhanyisiyo kunye nokungaphumeleli kombala. Ngokuqhelekileyo, le meko kukuba isibane ngokwaso sinengxaki. Inoba imanzi okanye itshiphu yeRGB yonakele. Indlela yethu yokulungisa ilula kakhulu, yithathele indawo nje ngamaso esibane esine-LED esinefektri. Izixhobo ezisetyenziswayo zi-tweezers kunye nemipu yomoya oshushu. Emva kokutshintsha izibane zesibane se-LED, sebenzisa Uvavanyo lwekhadi lokuvavanya kwakhona, ukuba akukho ngxaki, sele ilungisiwe.
2. Ingxaki "yombungu".
"I-Caterpillar" sisikweko nje, esibhekiselele kwinto yokuba ibha ende emnyama kwaye eqaqambileyo 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. Ngokuqhelekileyo, khangela ukuba isalathisi samandla e-LED sisebenza ngokuqhelekileyo. Ukuba isalathisi samandla e-LED asikhanyisi, ubukhulu becala kungenxa yokuba umbane wonakele. Yitshintshe nje entsha ngamandla 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 ekufuphi, 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.
