Ingabe uyakwazi ukubala ukusetshenziswa kwesibonisi sakho se-LED?
Imidiya yokukhangisa yangaphandle isiphenduke imidiya yangempela, futhi inani layo eliyingqayizivele elinevidiyo ekhanyayo futhi ekhangayo ayinakushintshwa.
Abantu abaningi bakhathazekile ngamandla esibonisi se-LED sangaphandle?Noma abalwa kanjani amandla esibonisi se-LED sangaphandle?
NamuhlaYONWAYTECHizonikeza isingeniso esifushane salezi zici.
Ngokuthuthuka kobuchwepheshe, imidiya yokukhangisa yangaphandle ihlala ivela.
Ngemva kokuba izethameli zomsakazo, ithelevishini, amaphephandaba, namamagazini ziqhubeka nokuhlukanisa, imidiya yokubonisa eholwa ukukhangisa isiphenduke imidiya yangempela enenani eliyingqayizivele ayikho enye indawo.
Okokuqala, mayelana nosayizi wamandla wezikrini zokubonisa eziholwa ngaphandle:
Kunezinhlobo ezimbili zamandla okubonisa i-LED: ukuphakama nesilinganiso.
Amandla abizwa ngokuthi amandla aphezulu kakhulukazi abhekisela ku-voltage esheshayo kanye nenani lamanje ekuqaleni kanye namandla lapho isikrini simhlophe sonke (sibonisa esimhlophe), kuyilapho amandla amaphakathi angamandla angaphansi kokusetshenziswa okuvamile.
Ayini amandla avamile wesibonisi se-LED sangaphandle?
Ngokuya ngamamodeli omkhiqizo ahlukene nabakhiqizi, amandla aphezulu amanje ezikrini zokubonisa ezinombala ogcwele ayahluka ukusuka ku-800W ukuya ku-1500W ngemitha yesikwele ngayinye.
Okwesibili, indlela yokubala yamandla esikrini sokubonisa esiholwa ngaphandle:
U-P umele amandla, u-U umele i-voltage, mina umele i-current.
Ngokuvamile amandla kagesi esiwasebenzisayo yi-5V, ukunikezwa kwamandla kungu-30A no-40A;isibonisi esiholwa ngombala owodwa singamamojula angu-8 kanye nogesi ongu-1 40A, futhi isikrini esinemibala emibili esinamamojula angu-6 ekunikezeni amandla oku-1;
Isibonelo sizonikezwa ngezansi.
Uma ufuna ukwenza amamitha-skwele angu-9 wesibonisi se-LED sangaphakathi se-P5 esinemibala emibili, bala amandla aphezulu adingekayo.
Okokuqala, bala inani lamandla kagesi angu-40A=9 (0.244×0.488)/6=12.5=13 amandla kagesi (inamba, ngokusekelwe esilinganisweni esikhulu), kulula kakhulu, amandla amakhulu P=13×40A×5V= 2600W.
Amandla esibani esisodwa = amandla esibani 5V*20mA=0.1W .
Amandla ebhodi leyunithi yesibonisi se-LED = amandla esibani esisodwa * ukulungiswa (inani lamaphikseli avundlile * inani lamaphikseli aqondile) / 2;amandla aphezulu esikrini = ukulungiswa kwesikrini * inani lezibani ngokulungiswa ngakunye * 0.1;Amandla amaphakathi = ukulungiswa kwesikrini * inombolo yezibani ngokulungiswa ngakunye * 0.1/2;amandla angempela esikrini = ukulungiswa kwesikrini * inombolo yezibani ngokulungiswa ngakunye * 0.1/inombolo yezikena (izikena ezingu-4, izikena ezingu-2, izikena ezingu-16 , izikena eziyi-8, ezimile).
Indlela yokubala amandla esikrini sokubonisa se-LED iwukubala inani lamaphoyinti, 0.3W/iphoyinti * inani lamaphoyinti amandla aphelele, futhi amandla amakhulu aphindaphindwa nge-factory engu-1.3.
Amandla amaphakathi cishe ayingxenye yamandla amakhulu.
Futhi intambo ngayinye yamandla idinga ukubona ukuthi mangaki amakhabethe e-LED ashayelayo, nokuthi mangaki amaphuzu abalwa, khona-ke amandla aphelele angabalwa.
1. Izidingo zokulungiswa kwesikrini se-LED:
Isibonisi esiholwa ngaphandle (hlala eningizimu futhi ubheke enyakatho): >4000CD/M2.
Isikrini esiholelekile sasendlini: >800CD/M2.
Amamojula aholwa ngasendlini encane: >2000CD/M2.
2. Amapharamitha amathathu wamandla wokubonisa we-LED wangaphandle:
Amandla amaphakathi esikrini = ukulungiswa kwesikrini * inani lezibani ngokulungiswa ngakunye * 0.1/2.
Amandla aphezulu esikrini = ukulungiswa kwesikrini * inani lezibani ngokulungiswa ngakunye * 0.1.,
Amandla wangempela esikrini = ukulungiswa kwesikrini * inani lezibani ngokulungiswa ngakunye * 0.1 / inani lamaskeni (4 scan, 2 scan, 16 scans, 8 scans, static).…
Okungenhla isingeniso esifushane mayelana namandla okubonisa i-LED yangaphandle nendlela yokubala, ngethemba ukuthi kuzoba usizo kuwe.
Ukuze uthole imininingwane eyengeziwe ukuze uthole ulwazi oluningiliziwe lwe-led display sicela uvumeleYONWAYTECHiqembu lazi.
