Yini Engayenza I-LED Yokonga Amandla Ebhizinisi Lakho Lokukhangisa Ngedijithali?
Isibonisi esihola ukonga amandla, esibizwa nangokuthi isikrini se-Common Anode Led.
I-chipset ye-LED inamatheminali amabili, i-anode ne-cathode, futhi i-LED ngayinye enombala ogcwele iqukethe ama-chipset amathathu e-LED. (obomvu, oluhlaza okotshani noluhlaza okwesibhakabhaka).
Emiklamo evamile ye-Common Anode, amatheminali awo wonke ama-LED angu-3 (abomvu, aluhlaza naluhlaza) axhunywe ndawonye futhi i-ballast resistor yangaphandle yengezwa ngochungechunge nge-LED ebomvu ukuze kugcinwe i-voltage engaguquki nokulinganisa ukwehla kwamandla kagesi kuwo wonke ama-LED amathathu.
Lokhu kamuva kunciphisa isikhala esitholakalayo sama-LED okwenza iphikseli enhle ibe nzima ukuyifinyelela, kuyilapho futhi kuwumthombo wokushisa owengeziwe futhi kusheshisa inqubo yokuguga futhi kunciphisa ukuphila konke.
Isibonisi se-LED esonga amandla samukela idizayini yesistimu yesibonisi ye-LED enamandla aphansi enombala ogcwele.
Kuwuhlelo lokusebenza lobunjiniyela bokuhlanganisa oluhlanganisa ubuchwepheshe obuhlukahlukene besimanje obunjengobuchwepheshe bekhompyutha, ubuchwepheshe be-elekthronikhi, ubuchwepheshe be-optical, ubuchwepheshe bukagesi kanye nobuchwepheshe besakhiwo.
Kubuchwepheshe be-Common Cathode, ama-voltage ahlukene, azinikele kagesi anikezwa ama-LED abomvu, aluhlaza naluhlaza avumela amandla anikezwa i-LED ebomvu ukuthi alawulwe ngokuhlukana futhi asuse imfuneko yesixhasi se-ballast.
Isikhathi sokudlala esikhulu, eside, kanye nokusetshenziswa kwayo kwamandla kuyinkomba eyinhloko ye-LED yokukhathazeka kwamakhasimendeIsibonisi esiwonga ngempela amandla asincikile kuphela ekuthuthukisweni kwezingxenyekazi zekhompuyutha ezithile noma kubuchwepheshe besofthiwe yesibonisi, kodwa futhi nomphumela wokuqamba okusha kwezobuchwepheshe kusixazululo sisonke.
Izikrini zokukhangisa ze-LED ezonga amandla, i-P4MM yangaphandle, i-P5.926MM, i-P6.67MM, i-P8MM, i-P10MM, ngemva kweminyaka yocwaningo nentuthuko kanye nokuqhathanisa okuvuthiwe kokuhlola, ukonga amandla angaphezu kuka-40% uma kuqhathaniswa nezikrini ze-LED zendabuko.
Ukunciphisa ukusetshenziswa kwamandla kwesikrini sokubonisa kuyisiqondiso esibalulekile sokuthuthukiswa kobuchwepheshe besikrini sesibonisi se-LED.
Izikrini ze-LED zokonga amandla zisebenzisa imiqondo yakamuva yedizayini, kucatshangelwa izici ezifana nezindleko, futhi ziklame ukusetshenziswa kwamandla aphansi kwezikrini zokubonisa ze-LED kusuka kuzici ezilandelayo:
A:Amalambu abomvu, aluhlaza naluhlazaanikwa amandla yi-3.8V futhi ukusebenza kahle kokuphakelwa kwamandla kungaphezulu kwama-85%.
B:Ukusebenzisa i-IC yokonga amandla ephezulu, i-voltage eguqukayo yesiteshi ephansi kakhulu, i-VDS = 0.2V, inciphisa kakhulu inani lamandla kagesi wesekethe yokushayela ye-LED.
C: Ukusetshenziswa kobuhlalu besibani esikhulu se-chip 1 izikhathi ezigqamile kunobuhlalu besibani be-LED obujwayelekile, ukuze ngaphansi kwezidingo ezifanayo zokukhanya, i-LED idinga ukushayela okuncane, okungukuthi, ukusetshenziswa kwamandla kuncishisiwe.
D: Uhlelo lokulawula oluhlakaniphileithuthukiswe ngokuzimela ingalungisa ngokuzenzakalelayo ukukhanya kwesikrini esikhulu se-LED ngokuya ngokukhanya kwemvelo yangaphandle, ukuze kungamoshi amandla noma kubangele ukungcoliswa kokukhanya.
E:Izibonisi ze-LED ezonga amandla, ngokusekelwe kuzikrini ezivamile ze-LED, zithuthukise ngokuhlelekile umphumela wokubonisa nokusebenza kokusetshenziswa kwamandla, ukuze umphumela wokusetshenziswa kwesibonisi se-LED kanye nokusetshenziswa kwamandla okuphelele kufinyelele amazinga ahamba phambili embonini.
Abanikazi bezokukhangisa bancamela izibonisi ze-LED ezinamandla okusebenza kahle.
Ngobuchwepheshe bokubonisa obujwayelekile be-cathode be-LED, izinga lokushisa lesikrini esiholayo lehlise ngo-12.4 degree.
Kulokhu kungasiza kakhulu ukufana kombala kanye nesikhathi eside sokuphila sokuboniswa kwe-LED.
Abahlomuli abaqondile kakhulu bezibonisi zokonga amandla e-LED kufanele kube abanikazi bokukhangisa bokukhangisa kwangaphandle, hhayi nje kuphela isikhathi eside sokuphila, kodwa futhi nokonga amandla lapho udonga lwevidiyo lukhanya isikhathi eside.
Xhumana ne-YONWAYTECH ukuze uthole isisombululo se-led esineziqondiso zokonga amandla.
