Isahluko sesithathu: Ukunikezwa Kwamandla E-LED Okufanelekayo / Abashayeli Besikrini Be-LED abadlala indima ebalulekile ekubonisweni okuholayo njengenhliziyo enomdlandla yomuntu.
Izibonisi ze-LED kancane kancane seziphenduke imikhiqizo evamile emakethe yedijithali yangaphandle yasekhaya, futhi zingabonakala yonke indawo kuma-facade wezakhiwo zangaphandle, isiteji sekhonsathi, namatheminali eziteshi, njll.
Kodwa sasivame ukuzwa abantu embonini bekhononda ngokuthi njalo lapho isibani se-LED siphukile, amacala afana namamojula ambalwa e-LED amnyama ngenxa yokuphulwa kwamandla kagesi, ukuyeka ukusebenza kwe-fan njll. Kudingeka ukuhlaziya ngokujulile ukuze uqonde imbangela ye-LED. ukulimala kokunikezwa kwamandla.
Ikakhulukazi, isikrini sokukhangisa sangaphandle sibhekene nesimo esinzima futhi sidinga ukunakekelwa okwengeziwe ukuze sikwazi ukusisebenzela kangcono.
Umthelela wokonga amandla wesibonisi se-LED nempilo yesevisi kuwumphumela osobala wokuphromotha, ngakho-ke ungakhomba kanjani ngendlela efanele futhi ukhethe ukunikezwa kwamandla okuboniswa kwe-LED okufanelekayo kwesikrini sakho esiqondisiwe?
Okokuqala, bheka inqubo yokubukeka ukuze ukhethe Ukunikezwa kwamandla esibonisi se-LED.
Umphakeli omuhle wamandla, futhi uqinile kakhulu enqubweni yokusebenza, ngoba lokhu kungaqinisekisa ukufana kweqoqo lomkhiqizo.
Kodwa umkhiqizi ongenandaba, ukukhiqizwa kwamandla Ukunikezwa kokubukeka kwayo, ithini, ukuhlelwa kwezinto akukuhle neze.
Okwesibili, khetha ukunikezwa kwamandla kwesibonisi se-LED kusukela ekusebenzeni kahle kokulayisha okugcwele.
Ukusebenza kahle kokunikezwa kwamandla kuyinkomba ebaluleke kakhulu, ukusebenza kahle izinga eliphezulu lokuguqulwa kwamandla liphezulu, ukuze linamathele ezidingweni zokongiwa kwamandla kanye nokuvikelwa kwemvelo, futhi lingasindisa ngempela ugesi kubasebenzisi.
Okwesithathu, i-voltage ripple yokuphuma kwamandla kagesi kagesi inkulu.
Ubukhulu bomphumela we-ripple bunomthelela omkhulu kakhulu empilweni yemishini kagesi.
I-ripple encane, iba ngcono.
Okwesine, qaphela ukwanda kwezinga lokushisa lokuhlinzekwa kwamandla ukuze ukhethe amandla esibonisi se-LED.
Ukwenyuka kwezinga lokushisa kuthinta ukuzinza nokuphila kokunikezwa kwamandla.
Uma izinga lokushisa liphansi, kungcono.
Ngaphezu kwalokho, kungabonakala ekusebenzeni kahle ukuthi ukusebenza kahle okujwayelekile kokushisa okuphezulu kuzoba kuncane.
Okwesihlanu, ngenxa yezakhiwo zemikhiqizo yokubonisa ye-LED, ushintsho lwamanje olusheshayo luzovame ukukhiqizwa lapho udlala ividiyo noma isikrini, esibeka phambili izidingo eziqinile ekunikezeni amandla e-LED.
Ngokuvamile, ukuze uqinisekise ukusakazwa okuvamile kwesikrini sokubonisa, udinga ukugcina inani elithile lesibonelelo sokunikezwa kwamandla.
Okwesithupha,I-mumqondo ojwayelekile we-ore, ukugcinwa kwensalela, ukusebenza komkhiqizo okuzinze kakhudlwana ukuphakelwa kukagesi, isikhathi eside sokuphila, nokho, ngalokho kukhulisa izindleko zemikhiqizo yokuphakelwa kukagesi, imali eningi eyinsalela futhi kulula ukubangela imfucuza.
Njengamanje, ukuhlinzekwa kwamandla okuhlinzekwa kwezikrini zokubonisa ze-LED embonini kuvame ukugcinwa ngo-20% - 30%.
Ukuze ukwandise isikhathi sokuphila kwamandla kagesi, kunconywa ukukhetha umshini onesilinganiso samandla esingu-30%.
Isibonelo, uma isistimu idinga ukunikezwa kwamandla okungu-100W, kunconywa ukuthi ukhethe imodeli enezilinganiso Zokunikezwa kwamandla ezingaphezu kuka-130W, ezingathuthukisa ngokuphumelelayo impilo yokunikezwa kwamandla.
Okwesikhombisa, khetha ukunikezwa kwamandla ngokwenkambu yesicelo.
Umsebenzi wokuvikela: ukuvikela i-voltage ngaphezulu, ukuvikela izinga lokushisa, ukuvikela ukulayisha ngokweqile, njll.
Ukulayisha ngokweqile kungase kubangele ukuvikeleka kokulayisha ngokweqile. Kunconywa ukwandisa amandla okukhipha amandla noma ukuguqula umklamo wokulayisha.
Esimeni sesibili, izinga lokushisa liphezulu kakhulu futhi ukuvikelwa kwezinga lokushisa kwenzeka, kokubili kuzobeka amandla esimweni esivikelekile.
Umsebenzi wohlelo lokusebenza: umsebenzi wesiginali, umsebenzi wokulawula kude, umsebenzi we-telemetry, umsebenzi ofanayo, njll.
Umsebenzi okhethekile: ukulungiswa komsebenzi (PFC), ugesi oqhubekayo (UPS).
Okwamanje, imithombo yamandla esetshenziswa yifekthri eholwa yi-yonwaytech yile: I-Meanwell, i-G-Energy, i-Rong Electric, i-Yuanchi, i-Chuanlian, i-Great Wall, njll.
I-Meanwell iyona ethandwa kakhulu, futhi i-Great Wall ingasetshenziswa kwamanye amazwe anesimo sezulu esibanda kakhulu, njengeRussia, iDenmark, iFinland kanye neSweden eNyakatho Yurophu.
