Lub zog yog dab tsi?

Ua ntej tshaj plaws, ua tsaug rau koj qhov kev mloog thiab muab qhov tseem ceeb rau tsab xov xwm no, thiab tos ntsoov rau koj qhov kev nyeem txuas ntxiv. Hauv cov ntsiab lus hauv qab no, peb yuav muab koj nrog kev paub txog kev paub zoo txog cov khoom siv teeb pom kev zoo, yog li thov nyob twj ywm.

Thaum xaiv LED teeb pom kev zoo, peb yuav xub them sai sai rau ntau qhov chaw xws li lub zog, lumen, xim kub, qib tsis muaj dej, cua sov dissipation, khoom siv thiab lwm yam. Los yog los ntawm kev sab laj cov khoom catalogs, mus saib cov vev xaib, siv Google tshawb fawb xyaw, saib YouTube yeeb yaj kiab lossis los ntawm lwm txoj hauv kev los nrhiav cov khoom pom zoo. Qhov tseeb, nws yog ib qho tseem ceeb rau cov neeg siv kom xa cov khoom no hauv lawv txoj kev txiav txim siab. Tab sis, koj puas paub tias tus nqi PF yog dab tsi?

Ua ntej, tus nqi PF (lub hwj chim qhov tseem ceeb) raws li lub hwj chim, tus nqi PF sawv cev rau lub cosine ntawm theem sib txawv ntawm cov input voltage thiab cov input tam sim no. Tus nqi ncaj qha cuam tshuam qhov kev ua tau zoo ntawm kev siv hluav taws xob hluav taws xob.

Hauv qab no yog ob qhov xwm txheej:

Rau LED lub teeb nrog tus nqi qis PF, hluav taws xob hluav taws xob yuav hloov mus rau hauv lub zog hluav taws xob thiab lwm yam ntawm lub zog thaum ua haujlwm. Ib feem ntawm lub zog hluav taws xob tsis tuaj yeem siv tau zoo thiab raug pov tseg.

Lwm qhov xwm txheej yog siv siab PF tus nqi LED teeb. Thaum nws pib, nws yuav ua tau zoo hloov hluav taws xob rau hauv lub teeb lub zog, yog li txuag lub zog noj thiab txo cov khoom pov tseg.

Tus nqi PF yog dav suav hais tias yog ib qho tseem ceeb rau kev ntsuas kev ua haujlwm ntawm LED teeb. Yog li ntawd, peb xav kom koj ua tib zoo saib thiab sib piv PF qhov tseem ceeb ntawm ntau hom thiab qauv thaum xaiv lub teeb LED. Nyob rau hauv txoj kev, qhov siab dua tus nqi PF, lub zog ua haujlwm ntau dua, thiab qhov cuam tshuam rau ib puag ncig yuav raug txo raws li.

Zuag qhia tag nrho, tus nqi PF yog qhov tseem ceeb thiab muaj txiaj ntsig tseem ceeb rau kev siv lub zog zoo. Yog li ntawd, thaum xaiv LED teeb, nws raug nquahu kom xav txog yam xws li lub zog, lumens, xim kub, kev ua haujlwm tsis muaj dej, muaj peev xwm ua kom sov, cov khoom siv, thiab lwm yam, thiab xyuam xim rau cov nqi siv ntawm PF tus nqi.
