Ungazikhetha kanjani izinto ezinhle zamandla ezibonisi ze-LED

Ukunikezwa kwamandla kuyingxenye ebalulekile yesibonisi se-LED. Ukunikezwa kwamandla okuhle kungasekela izibonisi ze-LED ukuze zisebenze isikhathi eside. Ngokuphambene, uma ukhetha ukunikezwa kwamandla kwekhwalithi ephansi, ngeke kuthinte ukusetshenziswa okuvamile kwesibonisi se-LED kuphela, kodwa futhi kungalimaza isibonisi se-LED futhi kubangele ukulahlekelwa. Ngakho-ke, kubalulekile ukuthola izinto ezinhle zamandla zokubonisa i-LED. Umbuzo uwukuthi ungakhetha kanjani izinsiza ezinhle zamandla? Sizokunikeza isingeniso esinemininingwane sokukhetha izinsiza zamandla ezithembekile zezibonisi ze-LED ngezansi.

 

1. Ukubukeka

Umkhiqizi omuhle wokuphakela amandla naye uqine kakhulu enqubweni yokukhiqiza yokuphakelwa kukagesi. Kuphela ngale ndlela canguarantee ukungaguquguquki imikhiqizo. Ukunikezwa kwamandla okunenqubo yokukhiqiza okuqinile kuzoba kuhle futhi kucoceke ngokubukeka, indawo ye-tin iba isicaba futhi igcwele, futhi izingxenye zihlelwe ngobunono, ukuze ukubukeka kwamandla kuzoba nezinkinga ezimbalwa ngemuva kokusetshenziswa isikhathi eside. Ngokuphambene nalokho, uma inqubo yokukhiqiza ingaqinile, ukubukeka kwezinto zamandla akubukeki kukuhle, futhi ikhwalithi ayifani neze nezibukeka kahle.

2. Ukusebenza kahle komthwalo ogcwele

Ukusebenza kahle kokunikezwa kwamandla kubaluleke kakhulu, futhi. Ukunikezwa kwamandla okusebenza kahle kakhulu kunokuguqulwa kwamandla aphezulu. Umkhawulo wokuguqulwa kwamandla okusebenza kahle kokuphakelwa kukagesi uncike ekusebenzeni kahle komthwalo wamandla kagesi. Ukuphakama komthwalo ogcwele ukusebenza kahle, ukuguqulwa kusheshe futhi kukhuphuke izinga lokusebenzisa. Ilayisha ngokugcwele izinsiza zikagesi ezisebenza kahle kakhulu azihlangabezani kuphela nezidingo zokonga amandla kanye nokuvikelwa kwemvelo, kodwa futhi zisiza abasebenzisi bonga amandla kanye nezindleko zokonga ugesi.

3. I-voltage ripple

Ngokuvamile, i-voltage ephumayo ye-aconstant voltage power supply inama-ripples amakhulu, futhi ubukhulu bama-rippleshas bunomthelela omkhulu kakhulu empilweni yezinto zokusebenza zikagesi. Uma ufuna ukuthi izinto ezinikezwa amandla zibe nempilo ende, kufanele uthole izinsiza zikagesi ezine-ripple encane ye-voltage. I-ripple encane, iba ngcono.

4. Izinga lokushisa liyakhuphuka

Ifana nemikhiqizo eminingi ye-elekthronikhi, Izimpahla zamandla zinenkinga yokukhuphuka kwezinga lokushisa ngemuva kokusetshenziswa isikhathi eside, futhi. Ukukhuphuka kwezinga lokushisa kuthinta ukuzinza kokunikezwa kwamandla futhi kuthinta impilo yonke yokunikezwa kwamandla. Ukukhuphuka kwezinga lokushisa okuphansi kokunikezwa kwamandla, kuba ngcono. Ngaphezu kwalokho, ukuphakama kwezinga lokushisa kwamandla asebenza kahle kakhulu kuzoba ngaphansi kwalawo angasebenzi kahle. Ukusebenza kahle kokunikezwa kwamandla kungachazwa ngokukhuphuka kwezinga lokushisa.

 

5. Ukungadingeki

Uma isibonisi se-LED sidlala ividiyo noma izithombe, okwamanje kuvame ukushintsha ngaso leso sikhathi, okudinga ukunikezwa kwamandla ukuthi kube nekhwalithi enhle. Ngokuvamile, ukuze uqinisekise ukuthi isibonisi se-LED singadlalwa ngokujwayelekile, kuyadingeka ukuthi izinto zikagesi zibe nokuphindaphindeka okuncane. Ngokuvamile, lapho kuba nokungadingeki, ukusebenza kwamandla kagesi kuzinzile, kanye nesikhathi eside sokuphila. Nokho, ukungasasebenzi okuningi kakhulu kuzodala ukonakala kalula futhi kwenyuse izindleko zokuphakelwa kukagesi. Njengamanje, izinsiza eziningi zikagesi zinesidingo sokuphinda sisebenze ngo-20% -30%, okuyisilinganiso esingabizi kakhulu.

6. Indawo yohlelo lokusebenza

Ukukhetha ukunikezwa kwamandla akumile.Inketho ethile incike endaweni ethile yohlelo lokusebenza. Ukunikezwa kwamandla okunemisebenzi ehlukahlukene kukhethwa ngokuya ngokwendawo yesicelo, njengemisebenzi yokuvikela: ukuvikela i-over-voltage, ukuvikelwa kwezinga lokushisa elingaphezulu, ukuvikela ukugcwala ngokweqile, njll.; imisebenzi yohlelo lokusebenza:umsebenzi wesiginali, umsebenzi wesilawuli kude, umsebenzi we-telemetry, ukuhambisana, njll.; Imisebenzi ekhethekile: ukulungiswa kwesici samandla (PFC), ukunikezwa kwamandla okungaphazamiseki (UPS).
