Okokuqala, ngiyabonga ngokunaka kwakho futhi ngibeka ukubaluleka kwalesi sihloko, futhi ngilangazelela ukufunda kwakho okuqhubekayo. Kokuqukethwe okulandelayo, sizokunikeza ulwazi oluningi lobuchwepheshe mayelana nemishini yokukhanyisa, ngakho-ke sicela uhlale ubukele.
Uma sikhetha ukukhanyisa kwe-LED, sizoqala ngokunaka izici eziningi ezifana namandla, i-lumen, izinga lokushisa lombala, izinga lokungangeni manzi, ukushabalalisa ukushisa, izinto zokwakha nokunye. Noma ngokubheka amakhathalogi emikhiqizo, ukuvakashela amawebhusayithi, ukusebenzisa izinjini zokusesha ze-Google, ukubuka amavidiyo e-YouTube noma ngezinye izindlela zokuthola imikhiqizo enconyiwe esezingeni eliphezulu. Empeleni, kubalulekile ukuthi abasebenzisi babhekisele kulezi zici enkambisweni yabo yokwenza izinqumo. Kodwa, uyazi ukuthi liyini inani le-PF?
Okokuqala, inani le-PF (i-power factor) njenge-power factor, inani le-PF limelela i-cosine yomehluko wesigaba phakathi kwe-voltage yokufaka kanye ne-input current. Inani lithinta ngqo ukusebenza kahle kokusetshenziswa kwamandla kagesi.
Lezi zimo ezimbili ezilandelayo:
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 iyachithwa.
Esinye isimo ukusebenzisa isibani se-LED esine-PF ephezulu. Uma siqalwa, sizoguqula amandla kagesi abe amandla okukhanya ngempumelelo, ngaleyo ndlela silondoloze ukusetshenziswa kwamandla futhi sinciphise imfucuza yamandla.
Inani le-PF libhekwa kabanzi njengenye yezinto ezibalulekile zokuhlola ukusebenza kokukhanya kwe-LED. Ngakho-ke, sincoma kakhulu ukuthi unake futhi uqhathanise amanani e-PF emikhiqizo namamodeli ahlukene lapho ukhetha ukukhanya kwe-LED. Ngendlela, lapho inani le-PF liphakeme, kulapho ukusebenza kahle kwamandla kukhuphuka khona, kanye nomthelela emvelweni kuzoncishiswa ngokufanele.
Sekukonke, inani le-PF liyisici esibalulekile futhi linenani elibalulekile lokubhekisela ekusetshenzisweni kwamandla ngendlela ephumelelayo. Ngakho-ke, lapho ukhetha ukukhanya kwe-LED, kunconywa ukuthi ucabangele izici ezifana namandla, ama-lumens, izinga lokushisa lombala, ukusebenza okungangeni manzi, amandla okushabalalisa ukushisa, izinto zokwakha, njll., futhi unake inani elibalulekile lokubhekisela lenani le-PF.
