Izinto eziphambili zezikrini ezinkulu ezikhokelweyo ziqulunqwa iibhlukhwe ezikhokelweyo kunye nabaqhubi be-IC. Ngenxa yobuntununtunu be-LED kwi-LED yombane oqingqiweyo, umbane ogqithisileyo unokubangela ukwahlukana kwee-Deods ezikhutshelweyo. Ke ngoko, amanyathelo okomhlaba kufuneka athathwe ngexesha lokufakwa kwezikrini ezinkulu ezikhokelayo ukuphepha umngcipheko wezibane ezifileyo.
I-01 ye-LED ye-LED ye-Screen
I-voltage esebenzayo yezikrini ezinkulu ezikhokelweyo ijikeleze i-5V, kwaye i-GARD REFT iphantsi kwe-20mma, iimpawu zomsebenzi ezikhokelayo zichonga umbane wombane kunye noxinzelelo lwangoku okanye uxinzelelo lwangoku. Oku kufuna ukuba sikwazi ukubona le nkqubo kwiNkqubo yokuSebenza kunye nokuSetyenziswa, sinike ingqalelo eyaneleyo, kwaye sithathe amanyathelo afanelekileyo okukhusela isikrini esikhulu se-LED. I-Sublour Sunning yindlela esetyenziswayo yokhuseleko esetyenziswayo kwizikrini ezinkulu ezikhokelayo.
Kutheni le nto amandla esibonelelo kufuneka sibekwe emhlabeni? Oku kuhambelana nendlela yokusebenza yokutshintsha kwamandla. Isibonelelo sethu sokukhutshelwa kweScreen Screen Screen Screen Sisixhobo esiguqula amandla e-AC 50V Mains kwi-DC ye-DC ye-DC yemveliso efana nokucoca ukucoca ukucoca ukucoca ukucoca ukucoca ukucoca ukucoca ukucoca i-procection. Ukuqinisekisa ukungcungcutheka kwe-AC / DC yokuGuquleka kwamandla, uMvelisi woNcedo lwaMandla uqhagamshele kwisekethe yokucoca i-EMI ukusuka kwi-wire ye-EMI kwi-wire yesekelo kwi-wire yesekethe ye-AC220V ye-3C ye-3C. Ukuqinisekisa uzinzo lwe-AC220V igalelo, onke amabakala aya kuba ne-leakulelo lokungena ngexesha lokusebenza, ngokuvuza okwangoku malunga ne-3.5mma. I-voltage evuza imalunga ne-110v.
Xa isikrini se-LED asibanga phantsi, ukuvuza okwangoku kungangabi kubangele ukonakala kwe-chip okanye isibane esivuthayo. Ukuba ingaphezulu kwama-20 imithombo isetyenziswa, ivumba eliqokelelweyo lifikelela kwi-70ma okanye ngaphezulu. Kwanele ukubangela ukuba uMkhuseli wokuvuza awenze kwaye anqumle umbane. Kungenxa yoko le nto izikrini zethu ze-LED azikwazi ukusebenzisa izikhuselo zokuvuza. Ukuba ukhuseleko lokuvuza aluxhunyiwe kwaye iscreen ye-LED ayifakwanga, eyona nto iphambili kunikezelo lwamandla luya kudlula kulomzimba wangoku. I-voltage ye-110v yanele ukubangela ukufa! Emva kokuphatha, i-voltage ye-Chembe yoNcedo lwamandla isondele kwi-0 yomzimba womntu. Ibonisa ukuba akukho mahluko onokubakho phakathi kokunikezelwa kwamandla kunye nomzimba womntu, kunye nokuvuza okwangoku kubhekiswa emhlabeni. Ke, isikrini se-LED kufuneka sibekwe.
I-02 Indlela echanekileyo kunye neembono eziphosakeleyo zezikrini zokubonisa ezikhoyo ze-LED
Abasebenzisi bahlala besebenzisa iindlela ezingachanekanga kwizikrini ze-LED, zihlala zibandakanya:
1. Kuyikholelwa ukuba isiphelo esisezantsi sakhiwo sangaphandle sekholamu siqhagamshelwe emhlabeni, ngenxa yoko akukho mfuneko yokuba umhlaba ubeke umhlaba wesikrini esikhulu;
2. Kukholelwa ukuba ubonelelo lwamandla luvaliwe kwibhokisi, kwaye iibhokisi ziqhagamshelwe omnye komnye ngokutshixa amabhongo kunye nezakhiwo, ngokomthetho oqingqiweyo kumelwe ukuba unikezo lwamandla luphakathi.
Kukho ukungaqondani kwezi ndlela zimbini. Iikholamu zethu ziqhagamshelwe kwi-bolts yesiseko, ezifakwe kwikhonkrithi. Ukuchasana kwekhonkrithi kungaphakathi kuluhlu lwe-100-500 ω. Ukuba ukuxhathisa umhlaba uphakame kakhulu, kuya kukhokelela ekuvusweni kwe-leakity okanye ukuvuza okungapheliyo. Ibhokisi yethu yebhokisi yokutshintshwa ngepeyinti, kwaye ipeyinti ngumqhubi wombane, oya kuthi unxibelelane nokunxibelelana ngebhokisi yebhokisi, kwaye unokubangela i-sparks yombane ukuze iphazamise umqondiso weZiko elikhulu leScreen. Ixesha elingaphezulu, umphezulu webhokisi enkulu yesikrini esikhokelayo okanye isakhiwo siya kufumana i-oxidation kunye ne-rust, kunye nezinto zokulungisa ezifana nezikrelemnqa ziya kukhululeka ngenxa yokwanda kwe-thermal kunye nokuchasana nolwahlulelo lwe-thermal. Oku kuyakukhokelela ekunyukini okanye ukusilela ngokupheleleyo kwesiphumo somhlaba we-LED. Yenza iingozi zokhuseleko. Ukuvela kweengozi zokhuseleko ezinjengokuvuza okwangoku, ukothuka kombane, ukuphazamiseka kunye nomonakalo kwiitshipsi.
Ke, yintoni efanele ibe ngumhlaba oqhelekileyo?
I-terminal yegalelo lamandla inee-terminal ezintathu ze-wiring, eziyile terminal ephilayo, iwindows engathathi hlangothi, kunye nesiphelo sendlela. Eyona ndlela ichanekileyo yokusebenzisa intambo yombala ophumeleleyo ophumeleleyo wokudibanisa kunye nokutshixa zonke izitoli zombane kwi-Wire yeWire Twinal terminalight terminal, kwaye emva koko ubakhokele ukuze banxibelelane nesiphelo sendlela. Ukuba akukho terminal yokufikelela kwisiza, inokudityaniswa kwimibhobho etshisiweyo enjengemibhobho yamanzi okanye imibhobho yentsimbi yentsimbi enokunxibelelana kakuhle nomhlaba. Ukuqinisekisa ukunxibelelana okuhle, i-welding ye-welding kwimizimba yendalo enjalo kufuneka yenziwe, kwaye ke ucingo olufihliweyo kufuneka luvaleleke ngokuqinileyo kwiziphelo ze-terminals ngaphandle kokudibanisa. Nangona kunjalo, imibhobho evuthayo kunye nokuqhuma efana negesi ayiyi kusetyenziswa. Okanye ukungcwaba i-elektroniki kwindawo. Umzimba owomileyo unokwenziwa nge-angle yentsimbi okanye imibhobho yentsimbi, engcwatyelwe ngokuthe tye okanye ngokuthe nkqo emhlabeni njengendawo elula yokuphakamisa. Inqaku lemihlaba kufuneka likhethwe kwindawo ekude ukuthintela abahambi ngeenyawo okanye izithuthi ezizonakalisa umzimba. Xa simhlaba, ukuxhathisa ubuganga kufuneka kungabi ngaphantsi kwe-4 i-ohms ukuqinisekisa ukukhutshwa ngexesha elifanelekileyo. Kufuneka kuqatshelwe ukuba isiphelo sendlela yokukhusela ukukhanya sifuna ixesha elithile lokuphazamiseka komhlaba ngexesha lokukhutshwa kombane, olunokukhokelela kulwando lwexesha elifutshane. Ukuba iscreen ye-LED ikhutshiwe kwi-terminal yokukhusela imibane, amandla anokubakho aphezulu kuneso sescreen se-LED, kwaye umbane okwangoku uya kudluliselwa kwi-wire ye-LORT, obangela ukonakala kwezixhobo. Ke ukuphakanyiswa kwezikrini ze-LED akunakudityaniswa kwi-terminal yokukhusela imibane, kunye nesiphelo sendlela yokukhusela kufuneka ubuncinci ibe ziimitha ezingama-20 ukusuka kwisiphelo sendlela yokukhusela ukukhanya. Thintela i-Countertattack yezinto ezinokubakho.
