Kutheni le nto imicu yokukhanya ifuna i-transformer?

1. Umgaqo wokusebenza wemigca yokukhanya

Umtya wokukhanya sisixhobo sombane esisebenzisa umgaqo okhanyayo wamaso wesibane se-LED ukuze sikhanyise ngokulawula umsinga. Ngenxa yokuba i-LED ngokwayo ine-voltage ephantsi yokusebenza, ngokubanzi phakathi kwe-2-3V, i-stabilizer yangoku okanye i-transformer iyadingeka ukuyilawula.

2. Kutheni imicu yokukhanya ifuna isiguquli?

1. Umbane akazinzanga

Imicu yokukhanya ineemfuno eziphezulu zombane osebenzayo, kwaye ngokubanzi kufuneka ibe ngaphakathi koluhlu lwamandla ombane olumiselweyo olufana ne-12V, 24V, 36V, njl. ukuze isebenze ngokufanelekileyo. Ukuba usebenzisa amandla e-220V AC ngokuthe ngqo, kuya kubangela iingxaki ezinjengokukhanya okungazinzanga kunye nobomi obufutshane bomgca wokukhanya.

2. Ukhuseleko

Umtya wokukhanya ngokwawo ubuthathaka, kwaye amandla ombane agqithise ngokulula anokubangela umonakalo okanye abangele iingozi zokhuseleko. Ukusetyenziswa kwe-transformer kunokuguqula i-voltage ephezulu ibe yi-voltage ephantsi efanelekileyo yokusebenza komgca wokukhanya, ukuqinisekisa ukusetyenziswa okukhuselekileyo komgca wokukhanya.

3. Umgaqo wokusebenza we-transformer

I-transformer yenziwe ngeekhoyili ezimbini kunye nombindi wentsimbi, kwaye iqonda ukuguqulwa kombane ngomgaqo wokungeniswa kwe-electromagnetic. Xa i-coil ephambili ye-transformer inamandla, i-flux yamagnetic yenziwa kwi-coil yentsimbi, ethi emva koko isebenze kwikhoyili yesibini ngokusebenzisa i-iron core, ibangela ukuba kuvele amandla e-electromotive kwi-coil yesibini.

Ngokomgaqo wokungeniswa kwe-electromagnetic, xa inani lokujika kwekhoyili yesibini likhulu kunelo coil ephambili, i-voltage ephumayo iya kuba phezulu kunombane wegalelo, kwaye ngokuchaseneyo.

Ngoko ke, xa ufuna ukuguqula amandla e-220V AC kwi-voltages ephantsi njenge-12V, i-24V, kunye ne-36V efanelekileyo yokusebenza kwesibane sesibane, kufuneka usebenzise kuphela i-transformer ukulungelelanisa umlinganiselo wokujika kwekhoyili.

4. Iindidi zeenguqu

Kwimicu yokukhanya, kukho iinguqu ezimbini ezisetyenziswa ngokuqhelekileyo: abaguquli bamandla kunye nezilawuli zamandla zangoku. Umguquli wamandla ngumbane oguqula i-220V (okanye i-110V) amandla e-AC ibe yi-12V (okanye i-24V) amandla e-DC. Imveliso yayo yangoku inokulawulwa ngokwenani lokutshintsha. Umlawuli wonikezelo lwamandla wangoku ulawula imveliso eqhubekayo ngoku ngokuhlengahlengisa i-voltage yepayipi ukuqinisekisa ukukhanya okuzinzile kokukhanya. Iintlobo ezimbini ze-transformers zikhethwa ngokweemeko ezahlukeneyo zesicelo kunye neemfuno.

5. Indlela yokukhetha i-transformer

Ukhetho oluchanekileyo lwe-transformer kufuneka lusekelwe ngokuthe ngqo kwiiparameters ezifana ne-voltage, amandla, okwangoku kunye nohlobo lokuqinisekisa ukukhanya okuzinzile kokukhanya kunye nokuphepha ukugqithisa kunye nokulimala kwi-transformer ngenxa yokukhethwa okungafanelekanga.
