Okokuqala, enkosi ngengqalelo yakho kwaye uncamathisele ukubaluleka kweli nqaku, kwaye ujonge phambili ekufundeni kwakho okuqhubekayo. Kulo mxholo ulandelayo, siya kukunika ubutyebi bolwazi lobuchwephesha malunga nezixhobo zokukhanyisa, ke nceda uhlale ubukele.
Xa sikhetha ukukhanya kwe-LED, siya kuqala sinikele ingqalelo kwizinto ezinama-multi-dimensional ezifana namandla, i-lumen, ukushisa kombala, ibakala elingangeni manzi, ukutshatyalaliswa kobushushu, izinto eziphathekayo kunye nokunye. Okanye ngokubonisana neekhathalogu zeemveliso, ukutyelela iiwebhusayithi, usebenzisa iinjini zokukhangela zikaGoogle, ukubukela iividiyo zeYouTube okanye ngezinye iindlela zokufumana iimveliso ezicetyiswayo ezisemgangathweni. eneneni, kubalulekile kubasebenzisi ukubhekisa le miba kwinkqubo yabo yokwenza izigqibo. Kodwa, ngaba uyazi ukuba yintoni ixabiso lePF?
Okokuqala, ixabiso le-PF (i-power factor) njengento yamandla, ixabiso le-PF libonisa i-cosine yokwahlukana kwesigaba phakathi kwe-voltage yegalelo kunye ne-input current. Ixabiso lichaphazela ngokuthe ngqo ukusebenza kakuhle kokusetyenziswa kwamandla ombane.
Ezi meko zimbini zilandelayo:
Ukukhanya kwe-LED ngexabiso eliphantsi le-PF, amandla ombane aya kuguqulwa abe ngamandla obushushu kunye nezinye iindlela zamandla ngexesha lokusebenza. Inxalenye yamandla ombane ayinakusetyenziswa ngokufanelekileyo kwaye iyachithwa.
Enye imeko isebenzisa ixabiso eliphezulu le-PF ukukhanya kwe-LED. Xa iqaliswa, iyakuguqula ngokufanelekileyo amandla ombane abe ngamandla alula, ngaloo ndlela igcine ukusetyenziswa kwamandla kunye nokunciphisa inkcitho yamandla.
Ixabiso lePF libhekwa ngokubanzi njengenye yezinto ezibalulekileyo zokuvavanya ukusebenza kokukhanya kwe-LED. Ngoko ke, sincoma kakhulu ukuba ubeke ingqalelo kwaye uthelekise amaxabiso e-PF eemveliso ezahlukeneyo kunye neemodeli xa ukhetha ukukhanya kwe-LED. Ngendlela, ukuphakama kwexabiso le-PF, ukuphakama kwamandla okusebenza kakuhle, kunye nempembelelo kwindalo iya kuncitshiswa ngokufanelekileyo.
Ngokubanzi, ixabiso lePF liyinto ebalulekileyo kwaye inexabiso elibalulekileyo lokubhekisela ekusebenziseni ngokufanelekileyo amandla. Ngoko ke, xa ukhetha ukukhanya kwe-LED, kucetyiswa ukuba uqwalasele izinto ezifana namandla, i-lumens, ukushisa kombala, ukusebenza kwamanzi, amandla okutshatyalaliswa kobushushu, izinto eziphathekayo, njl., kwaye ubeke ingqalelo kwixabiso lokubhekisela kwixabiso le-PF.
