LED yerekana ibicuruzwa bya elegitoroniki. Igihe cyose ari ibicuruzwa bya elegitoronike, byanze bikunze bizananirana mugihe cyo gukoresha. None ni ubuhe nama bwo gusana LED yerekana?
Inshuti zagiye zikorana na LED zerekana ko LED yerekanwe hamwe igice kimwe cya LED. Nkuko byavuzwe haruguru, ecran ya LED ni ibicuruzwa bya elegitoroniki, bityo imiterere yacyo yibanze nubuso bwerekana (hejuru yamatara), PCB (ikibaho cyumuzunguruko), hamwe nubugenzuzi (IC bigize ubuso).
Tuvuze inama zo gusana LED yerekanwe, reka tubanze tuvuge amakosa asanzwe. Amakosa akunze kuboneka arimo: "amatara yapfuye" igice, "caterpillars", igice kibura amabara igice, ibara ry'umukara igice, ecran nini yumukara, kode yimyenda igice, nibindi.
Nigute ushobora gusana ibyo bibazo bisanzwe? Ubwa mbere, tegura ibikoresho byo gusana. Ibice bitanu byubutunzi kubakozi bashinzwe kubungabunga LED yerekana: tewers, imbunda yo mu kirere ishyushye, icyuma cyo kugurisha, multimeter, ikarita yikizamini. Ibindi bikoresho bifasha birimo: kugurisha paste (tin wire), flux kuzamura, insinga z'umuringa, kole, nibindi.
1. Ikibazo "urumuri rwapfuye" igice
"Itara ryapfuye" ryaho bivuga ko itara rimwe cyangwa byinshi hejuru yigitereko cyamatara ya LED kitagaragara. Ubu bwoko bwo kutamurika bugabanijwemo umwanya-wose utamurika no gutsindwa kwamabara igice. Mubisanzwe, iki kibazo nuko itara ubwaryo rifite ikibazo. Yaba itose cyangwa chip ya RGB yangiritse. Uburyo bwacu bwo gusana buroroshye cyane, gusa ubusimbuze namashanyarazi ya LED yamashanyarazi. Ibikoresho byakoreshejwe ni tweger hamwe nimbunda zishyushye. Nyuma yo gusimbuza amatara ya LED yamashanyarazi, koresha Ongera ikarita yikizamini, niba ntakibazo, yarasanwe.
2. Ikibazo "caterpillar"
"Caterpillar" ni imvugo ngereranyo gusa, yerekeza ku kintu cyerekana ko umurongo muremure wijimye kandi wijimye ugaragara ku gice cy’itara igihe urumuri rwa LED rukoreshwa kandi nta soko ryinjiza, kandi ibara ahanini ritukura. Intandaro yibi bintu ni ukumeneka kwimbere yimbere y itara, cyangwa umuzenguruko mugufi wumurongo wa IC hejuru yumurongo wa tara, iyambere ni myinshi. Mubisanzwe, iyo ibi bibaye, dukeneye gusa gukoresha imbunda ishyushye kugirango duhumeke umwuka ushushe "caterpillar". Iyo ihuhije itara riteye ikibazo, mubisanzwe nibyiza, kuko ubushyuhe butera chip imbere kumeneka. Yarafunguwe, ariko haracyari akaga kihishe. Tugomba gusa gushakisha itara rya LED rimeneka, tugasimbuza iri tara ryihishe ukurikije uburyo twavuze haruguru. Niba ari umuzenguruko mugufi wumurongo wumurongo kuruhande rwinyuma rwa IC, ugomba gukoresha multimeter kugirango upime IC pin umuzenguruko ujyanye no kuyisimbuza IC nshya.
3. Ibice bimwe byamabara yabuze
Inshuti zimenyereye LED zerekana zigomba kuba zarabonye ikibazo nkiki, ni ukuvuga, kare kare ntoya itandukanye yamabara agaragara mugihe LED yerekanwe ikina bisanzwe, kandi ni kare. Iki kibazo muri rusange nuko ibara IC inyuma yibara ryibara ryaka. Igisubizo nukuyisimbuza IC nshya.
4. Igice cyumukara igice nigice kinini cyumukara
Muri rusange, ecran yumukara bivuze ko mugihe LED yerekana ecran ikina mubisanzwe, imwe cyangwa nyinshi LED modules yerekana phenomenon ko agace kose kataba keza, kandi ubuso bwa moderi nkeya LED ntabwo iba yaka. Tuyita igice cyirabura igice. Twise uturere twinshi. Nibinini binini byirabura. Iyo ibi bintu bibaye, mubisanzwe tubanza gutekereza kubintu byingufu. Mubisanzwe, reba niba icyerekezo cya LED gikora gisanzwe. Niba icyerekezo cy'amashanyarazi LED kitamurika, ni ukubera ko amashanyarazi yangiritse. Gusa ubisimbuze bishya hamwe nimbaraga zijyanye. Ugomba kandi gusuzuma niba umugozi wamashanyarazi ya LED module ihuye na ecran yumukara irekuye. Mubihe byinshi, kongera kugoreka urudodo birashobora kandi gukemura ikibazo cyumukara.
5. imyanda igice
Ikibazo cya kode yimyenda yaho iragoye. Yerekeza kuri phenomenon ya random, idasanzwe, kandi birashoboka guhinduranya amabara mugace kamwe mugihe ecran ya LED ikina. Iyo ubu bwoko bwikibazo bubaye, mubisanzwe tubanza gukemura ikibazo cyumurongo wumurongo uhuza, urashobora kugenzura niba umugozi uringaniye watwitse, niba insinga y'urusobe irekuye, nibindi. Mubikorwa byo kubungabunga, twasanze insinga ya aluminium-magnesium yoroshye gutwika, mugihe umugozi wumuringa usukuye ufite ubuzima burebure. Niba ntakibazo cyo kugenzura ibimenyetso byose bihuza, hanyuma uhanahana module ya LED iteye ikibazo hamwe na module isanzwe ikinirwa, urashobora guca urubanza niba bishoboka ko module ya LED ihuye nikibuga kidasanzwe cyangiritse, nimpamvu yabyo ibyangiritse ahanini nibibazo bya IC. , Ibikorwa byo kubungabunga bizaba bigoye cyane. Ntabwo nzajya muburyo burambuye hano.
