Chii chinonzi simba?

Chekutanga, ndinokutendai nekutarisisa kwenyu uye nekuisa kukosha kuchinyorwa ichi, uye kutarisira kuenderera mberi nekuverenga kwako. Mune zvinotevera zvirimo, tinokupa hupfumi hweruzivo rwehunyanzvi nezvemidziyo yekuvhenekesa, saka ndapota gara wakatarisa.

Pakusarudza mwenje we LED, isu tichatanga tateerera kune akawanda-dimensional zvinhu senge simba, lumen, tembiricha yemavara, giredhi rekusapinda mvura, kupisa kupisa, zvinhu uye zvichingodaro. Kana nekutarisa zvigadzirwa, kushanyira mawebhusaiti, uchishandisa Google kutsvaga injini, kuona YouTube mavhidhiyo kana nedzimwe nzira dzekuwana mhando dzakakurudzirwa zvigadzirwa. chaizvo, zvakakosha kuti vashandisi vataure zvinhu izvi mukuita kwavo sarudzo. Asi, unoziva chii chinonzi PF kukosha?

Chekutanga, kukosha kwePF (simba chinhu) sechinhu chesimba, kukosha kwePF kunomiririra cosine yemusiyano wechikamu pakati pemagetsi ekuisa uye ekuisa ikozvino. Kukosha kunokanganisa zvakananga kushanda kwekushandiswa kwesimba remagetsi.

Izvi zvinotevera mamiriro maviri:

Kune mwenje we LED ine yakaderera PF kukosha, simba remagetsi richashandurwa kuita kupisa uye mamwe marudzi esimba panguva yekushanda. Chikamu chesimba remagetsi hachigoni kushandiswa zvakanaka uye chinoparara.

Imwe mamiriro anoshandisa yakakwirira PF kukosha kwe LED mwenje. Kana yatangwa, inonyatso shandura simba remagetsi kuita simba rakareruka, nekudaro kuchengetedza kushandiswa kwesimba uye kuderedza kutambisa simba.

Iko kukosha kwePF kunoonekwa zvakanyanya sechimwe chezvinhu zvakakosha pakuongorora kushanda kwechiedza che LED. Naizvozvo, isu tinokurudzira zvakasimba kuti iwe uteerere uye uenzanise kukosha kwePF yemhando dzakasiyana uye mhando pakusarudza mwenje we LED. Nenzira, iyo yakakwira kukosha kwePF, iyo yakakwira simba rekushandisa, uye kukanganisa kune nharaunda kunodzikiswa zvinoenderana.

Pakazara, kukosha kwePF chinhu chakakosha uye ine kukosha kwakakosha kwekushandisa kwesimba. Naizvozvo, pakusarudza mwenje we LED, zvinokurudzirwa kufunga zvinhu zvakaita sesimba, lumens, tembiricha yeruvara, kusapinda kwemvura, simba rekubvisa kupisa, zvinhu, nezvimwewo, uye teerera kune kukosha kweiyo PF kukosha.
