Okokuqala, ngiyabonga ngokunaka kwakho futhi unamathisele ukubaluleka kwalesi sihloko, futhi ngibheke phambili ekufundeni kwakho okuqhubekayo. Kokuqukethwe okulandelayo, sizokunikeza ingcebo yolwazi lochwepheshe mayelana nemishini yokukhanyisa, ngakho-ke sicela uhlale ubukele.
Lapho sikhetha ukukhanyisa kwe-LED, sizoqala sinake izici eziningi-dimensional ezifana namandla, i-lumen, izinga lokushisa lombala, ibanga elingangeni manzi, ukuchithwa kokushisa, izinto ezibonakalayo nokunye. Noma ngokubheka ikhathalogi yemikhiqizo, ngokuvakashela amawebhusayithi, usebenzisa izinjini zokusesha ze-Google, ukubuka amavidiyo e-YouTube noma ngezinye izindlela zokuthola imikhiqizo enconyiwe yekhwalithi. empeleni, kubalulekile ukuthi abasebenzisi babhekise lezi zici enqubweni yabo yokuthatha izinqumo. Kodwa, uyazi ukuthi liyini inani le-PF?
Okokuqala, inani le-PF (isici samandla) njengesici samandla, inani le-PF limelela i-cosine yomehluko wesigaba phakathi kwe-voltage yokufaka kanye nokufakwayo kwamanje. Inani lithinta ngokuqondile ukusebenza kahle kokusetshenziswa kwamandla kagesi.
Okulandelayo yizimo ezimbili:
Ngokukhanya kwe-LED okunenani eliphansi le-PF, amandla kagesi azoguqulwa abe amandla okushisa nezinye izinhlobo zamandla ngesikhathi sokusebenza. Ingxenye yamandla kagesi ayikwazi ukusetshenziswa kahle futhi iyamoshwa.
Esinye isimo sisebenzisa ukukhanya okuphezulu kwe-PF ye-LED. Uma iqalwa, izoguqula kahle amandla kagesi ibe amandla alula, ngaleyo ndlela yonge ukusetshenziswa kwamandla futhi yehlise ukumosheka kwamandla.
Inani le-PF libhekwa kabanzi njengenye yezinto ezibalulekile zokuhlola ukusebenza kokukhanya kwe-LED. Ngakho-ke, sincoma ngokuqinile ukuthi unake futhi uqhathanise amanani e-PF emikhiqizo ehlukene namamodeli lapho ukhetha ukukhanya kwe-LED. Ngendlela, ukuphakama kwevelu ye-PF, kukhuphuka amandla okusebenza kahle, kanye nomthelela emvelweni kuzoncishiswa ngokufanele.
Sekukonke, inani le-PF liyisici esibalulekile futhi linenkomba ebalulekile yokusetshenziswa kwamandla ngendlela efanele. Ngakho-ke, lapho ukhetha ukukhanya kwe-LED, kunconywa ukucabangela izici ezifana namandla, ama-lumens, izinga lokushisa lombala, ukusebenza okungangeni manzi, amandla okukhipha ukushisa, izinto ezibonakalayo, njll., futhi unake inani lereferensi yenani le-PF.
