Yintoni i-power factor?

Okokuqala, enkosi ngengqalelo yakho kwaye unike eli nqaku ukubaluleka, kwaye ndilangazelela ukufunda kwakho okuqhubekayo. Kolu mxholo ulandelayo, siza kukunika ulwazi oluninzi malunga nezixhobo zokukhanyisa, ngoko ke nceda uhlale ubukele.

Xa sikhetha ukukhanya kwe-LED, siza kuqala siqwalasele izinto ezinemilinganiselo emininzi efana namandla, ukukhanya kwe-lumen, ubushushu bombala, umgangatho wokungangeni manzi, ukusasazwa kobushushu, izinto ezisetyenziswayo, njl. Okanye ngokujonga kwiikhathalogu zemveliso, ukutyelela iiwebhusayithi, ukusebenzisa iinjini zokukhangela zikaGoogle, ukubukela iividiyo zeYouTube okanye ngezinye iindlela zokufumana iimveliso ezicetyiswayo ezisemgangathweni. Enyanisweni, kubalulekile ukuba abasebenzisi babhekisele kwezi zinto kwinkqubo yabo yokwenza izigqibo. Kodwa, uyazi ukuba lithini ixabiso le-PF?

Okokuqala, ixabiso le-PF (i-power factor) njenge-power factor, ixabiso le-PF limele i-cosine yomahluko wesigaba phakathi kwe-input voltage kunye ne-input current. Ixabiso lichaphazela ngokuthe ngqo ukusebenza kakuhle kokusetyenziswa kwamandla ombane.

Ezi zilandelayo ziimeko ezimbini:

Kwisibane se-LED esinexabiso eliphantsi le-PF, amandla ombane aya kuguqulwa abe ngamandla obushushu kunye nezinye iintlobo zamandla ngexesha lokusebenza. Inxalenye yamandla ombane ayinakusetyenziswa ngokufanelekileyo kwaye iyachithwa.

Enye imeko kukusebenzisa isibane se-LED esinexabiso eliphezulu le-PF. Xa siqaliswa, siya kuguqula amandla ombane abe ngamandla okukhanya ngokufanelekileyo, ngaloo ndlela sigcine ukusetyenziswa kwamandla kwaye sinciphise inkunkuma yamandla.

Ixabiso le-PF lithathwa ngokubanzi njengenye yezinto ezibalulekileyo zokuvavanya ukusebenza kwesibane se-LED. Ke ngoko, sicebisa kakhulu ukuba unike ingqalelo kwaye uthelekise amaxabiso e-PF eempawu ezahlukeneyo kunye neemodeli xa ukhetha isibane se-LED. Ngendlela, okukhona ixabiso le-PF liphezulu, kokukhona ukusebenza kakuhle kwamandla, kunye nefuthe kwindalo esingqongileyo liya kuncipha ngokufanelekileyo.

Lilonke, ixabiso le-PF libalulekile kwaye linexabiso elibalulekileyo lokusetyenziswa kwamandla ngokufanelekileyo. Ke ngoko, xa ukhetha isibane se-LED, kuyacetyiswa ukuba uqwalasele izinto ezinje ngamandla, ii-lumens, ubushushu bombala, ukusebenza kokungena kwamanzi, amandla okusasaza ubushushu, izinto, njl.njl., kwaye unikele ingqalelo kwixabiso elibalulekileyo lokusetyenziswa kwamandla.
