Izakhi eziyisisekelo zezikrini ezinkulu ze-LED zakhiwa ubuhlalu be-LED kanye nabashayeli be-IC. Ngenxa yokuzwela kwama-LEDs kugesi oqinile, ugesi owedlulele ngokweqiniso ungadala ukwehla kwama-diode akhanyise ama-diode. Ngakho-ke, izinyathelo eziphansi kufanele zithathwe ngesikhathi sokufakwa kwezikrini ezinkulu ze-LED ukugwema ubungozi bezibani ezifile.
I-01 isibuko se-LED Screen Poliction
I-voltage esebenzayo yezikrini ezinkulu ze-LED zizungeze i-5V, futhi i-General isebenza yamanje ingaphansi kwe-20MA, izici ezisebenzayo ze-LEDs zinquma ubungozi bawo kugesi we-state kanye ne-abnoral voltage noma ukushaqeka kwamanje. Lokhu kudinga ukuthi sikubone lokhu ekukhiqizweni nasekusetshenzisweni kwenqubo, nikeza ukunakwa okwanele, futhi kuthathe izinyathelo ezisebenzayo ukuvikela isikrini esikhulu se-LED. Futhi indawo yamandla yindlela esetshenziswa kakhulu yokuvikela izikrini ezinkulu eziholwa.
Kungani ukulethwa kwamandla kudinga ukuba kusekelwe? Lokhu kuhlobene nemodi yokusebenza yokushintshwa kwamandla okushintsha. Ukuhlinzekwa kwamandla okukhulu kwesikrini esikhulu se-LED kuyinto eguqula amandla e-AC 220V mains amandla ekunikezelweni kwamandla kwe-DC 5v DC yokukhishwa kwezindlela ezizinzile ngochungechunge lwezindlela ezifana nokuhlunga kabusha kwezindlela zokulungisa izindlela zokuhlunga. Ukuze uqinisekise ukuqina kokuguqulwa kwe-AC / DC kokuhlinzekwa kwamandla, umenzi wokuhlinzeka ngamandla uxhume umjikelezo wokuhlunga we-EMI kusuka ku-wire bukhoma uye ohlelweni lomhlaba we-ac220s terminal ye-3C efakwa ezweni ngokuhambisana ne-Qundational National 3C. Ukuqinisekisa ukuqina kokufaka kwe-AC220V, zonke izinto zamandla zizoba nokuhlunga ukuvuza ngesikhathi sokusebenza, ngesilinganiso sokuvuza esingama-3.5MA ukuze anikeze i-3.5MA ukuze uthole amandla afanayo. I-voltage yokuvuza cishe i-110V.
Lapho isikrini se-LED singesisekelo, ukuvuza kwamanje kungenzeka kungabingela ukulimala kwe-chip noma isibani sesibani. Uma kusetshenziswa imithombo kagesi engaphezu kwama-20, ukuvuza okuqongelelwe kwamanje kufinyelela kuma-70m noma ngaphezulu. Kwanele ukwenza umvikeli ovuzayo ukuba enze futhi anqume ukunikezwa kwamandla. Lokhu futhi kungani izikrini zethu ze-LED zingakwazi ukusebenzisa abavikeli abavuzayo. Uma ukuvikelwa ukuvuza kungaxhunyiwe futhi isikrini se-LED asinasisekelo, amanje akhona okuphephelwa kwamandla angeqa ukuphepha kwamanje komzimba womuntu. I-voltage ka-110V yanele ukubangela ukufa! Ngemuva kokubeka phansi, amavoluti okuhlinzekwa kwamandla okuthengiswayo asondele ku-0 emzimbeni womuntu. Kubonisa ukuthi akukho mehluko ongaba khona phakathi kokunikezwa kwamandla kanye nomzimba womuntu, kanye nokuvuza kwamanje kuqondiswe emhlabathini. Ngakho-ke, isikrini se-LED kumele sibe yinkohliso.
02 Indlela Elungile Nemibono Eyiphutha Yezikrini Zokuboniswa Kwe-LED
Abasebenzisi bavame ukusebenzisa izindlela ezingesilo izikrini eziholwa yi-LED Screens, evame ukufaka:
1. Kukholelwa ukuthi ukuphela okuphansi kwesakhiwo sekholamu yangaphandle kuxhunyiwe emhlabathini, ngakho-ke asikho isidingo sokuthola isikrini esikhulu se-LED;
2. Kukholakala ukuthi ukunikezwa kwamandla kukhiyelwe ebhokisini, futhi amabhokisi axhumene komunye nomunye ngokukhiya amabhande nezinhlaka ezihlelekile, ngakho-ke isisekelo sesakhiwo simele ukunikezwa kwamandla.
Kukhona ukungaqondani kulezi zindlela ezimbili. Amakholomu ethu axhunyiwe kwizisekelo ze-anchor bolts, ezifakwe kukhonkolo. Ukumelana nokhonkolo kungaphakathi kwebanga le-100-500 ω. Uma ukumelana okuyisisekelo kuphezulu kakhulu, kuzoholela ekuvuzweni okungazelelwe noma ukuvuza okusele. Ibhokisi lethu lebhokisi lifafazwe ngopende, futhi upende ngumqhudeli ompofu kagesi, ozodala ukuthi axhumane nomqondo ompofu noma ukumelana kwezisekelo ekuphazamisekeni kwesibonakaliso somzimba omkhulu we-LED. Ngokuhamba kwesikhathi, ingaphezulu lebhokisi lesikrini esikhulu se-LED noma ukwakheka kuzozwa i-oxidation nokugqwala, kanye nokulungisa izingxenye ezinjengezikulufo zizokhulula kancane kancane ngenxa yokwandisa okushisayo. Lokhu kuzoholela ekuhlulekeni okusebenzayo noma okuphelele okuphelele komphumela onesisekelo wesakhiwo se-LED Screen. Dala izingozi zokuphepha. Ukuvela kwezingozi zokuphepha njengokuvuza kwamanje, ukushaqeka kukagesi, ukuphazanyiswa kanye nomonakalo kuma-chip.
Ngakho-ke, yini okufanele ibe yindawo evamile?
I-terminal yokufaka yamandla inezindawo ezintathu ezinama-wiring, okungukuthi i-line terminal ebukhoma, i-terminal engathathi hlangothi, kanye ne-terminal. Indlela efanelekile yokusebenzisa umugqa ophuzi ophuzi ophuzi ophuzi wombala ophuzi ukuze uxhume futhi ukhiye wonke ama-terminals we-wire yomhlaba ochungechungeni, bese uwaholela ekuxhumeni esiteji esiphansi. Uma kungekho terminal enesisekelo esizeni, kungaxhunywa kumapayipi angcwatshwe njengamapayipi amanzi ensimbi noma amapayipi wensimbi ensimbi axhumana kahle nomhlaba. Ukuqinisekisa ukuthintana okuhle, ama-welding terminals emidumeni enjalo yemvelo yemvelo kufanele yenziwe, bese kuthi umugqa womhlabathi kufanele uvalwe ngokuqinile kuma-terminals ngaphandle kokuxhuma okubophayo. Kodwa-ke, amapayipi avuthayo futhi aqhumayo anjengegesi ngeke asetshenziswe. Noma ngcwaba ama-electrodes asemhlabeni esizeni. Umzimba onesisekelo ungenziwa ngamapayipi ensimbi e-angle noma ensimbi, angcwatshwe ngokuqondile noma ngokuqondile emhlabathini njengendawo elula yesisekelo. Iphuzu eliyisisekelo kufanele likhethwe endaweni eyihlane ukuvikela abahamba ngezinyawo noma izimoto ekulimazeleni umzimba ophansi. Lapho sisemhlabathini, ukumelana kwesisekelo kufanele kube ngaphansi kwama-4 ohms ukuqinisekisa ukukhishwa okufika ngesikhathi sokuvuza kwamanje. Kumele kwaziwe ukuthi i-terminal evikelekile yombani idinga inani elithile lesikhathi sokuvikelwa komhlaba wamanje ngesikhathi sokukhishwa kombani kwamanje, okungaholela ekukhuphukeni kwamandla emhlabathini ngesikhathi esifushane. Uma isikrini se-LED sisekelwa esitokisini esivikelekile sombani, amandla omhlabathi azoba ngaphezulu kwalesi sikrini esiholwa, futhi kuzotholwa umbani we-LED esikrinini esiholwa esikrinini. Ngakho-ke indawo yokuvikela yezikrini eziholwa izikrini ayinakuxhunyaniswa esigungwini sokuvikelwa kombani, futhi i-terminal evikelayo kufanele okungenani ibe ngamamitha angama-20 kude nesivikelo esivinjelwe sombani. Vikela umphikisi wekhono lomhlaba.
