Mphamvu yamagetsi ndi chiyani?

Choyamba, zikomo chifukwa cha chidwi chanu ndikuyika kufunikira kwa nkhaniyi, ndikuyembekezera kuwerenga kwanu kopitilira muyeso.Muzotsatirazi, tikupatseni chidziwitso chaukadaulo chokhudza zida zowunikira, chonde khalani tcheru.

Posankha kuunikira kwa LED, choyamba tidzatchera khutu kuzinthu zambiri monga mphamvu, lumen, kutentha kwa mtundu, kalasi yopanda madzi, kutaya kutentha, zinthu ndi zina zotero.Kapena poyang'ana m'mabuku azinthu, kuyendera mawebusayiti, kugwiritsa ntchito injini zosaka za Google, kuwonera makanema a YouTube kapena njira zina zopezera zinthu zabwino zomwe zikulimbikitsidwa.kwenikweni, ndikofunikira kuti ogwiritsa ntchito afotokoze izi popanga zisankho.Koma, kodi mukudziwa kuti PF mtengo ndi chiyani?

Choyamba, mtengo wa PF (mphamvu yamagetsi) monga mphamvu yamagetsi, mtengo wa PF umayimira cosine wa kusiyana kwa gawo pakati pa magetsi olowera ndi magetsi olowera.Mtengowo umakhudza mwachindunji kugwiritsa ntchito mphamvu zamagetsi.

Zotsatirazi ndi ziwiri:

Kwa kuwala kwa LED komwe kumakhala ndi mtengo wotsika wa PF, mphamvu zamagetsi zidzasinthidwa kukhala mphamvu ya kutentha ndi mphamvu zina panthawi yogwira ntchito.Gawo la mphamvu zamagetsi silingagwiritsidwe ntchito moyenera ndipo limawonongeka.

Chinthu china ndikugwiritsa ntchito kuwala kwa LED kwamtengo wapatali wa PF.Ikangoyambika, isintha bwino mphamvu yamagetsi kukhala mphamvu yopepuka, potero imapulumutsa kugwiritsa ntchito mphamvu ndikuchepetsa kuwononga mphamvu.

Mtengo wa PF umadziwika kuti ndi chimodzi mwazinthu zofunika pakuwunika momwe kuwala kwa LED kumayendera.Chifukwa chake, tikukulimbikitsani kuti mumvetsere ndikufanizira mfundo za PF zamitundu ndi mitundu yosiyanasiyana posankha kuwala kwa LED.Momwemo, kuchuluka kwa mtengo wa PF, kukweza mphamvu zamagetsi, komanso kukhudzidwa kwa chilengedwe kudzachepetsedwa moyenerera.

Ponseponse, mtengo wa PF ndiwofunikira kwambiri ndipo uli ndi tanthauzo lofunikira pakugwiritsa ntchito mphamvu moyenera.Choncho, posankha kuwala kwa LED, tikulimbikitsidwa kuti tiganizire zinthu monga mphamvu, lumens, kutentha kwa mtundu, madzi osagwira ntchito, mphamvu zowononga kutentha, zinthu, ndi zina zotero, ndikumvetsera mtengo wamtengo wapatali wa PF.
