Ake sibone ukuthi izibani ze-DEL dimmer zikhona

Ukukhanya kwe-LED nsuku zonke kuthola abalandeli abaningi. Ngokuphindaphindiwe emakhaya nasemaphandleni ungathola amadivaysi ekukhanyisa ama-semiconductor. Labo abaye banquma ukufaka ngokwabo efulethini lolu hlobo lokukhanyisa futhi baqala ukuqoqa ulwazi mayelana nezibani ezinjalo, qhathanisa izinzuzo kanye nokuqhafaza, bavame ukuhlangana nomqondo onjalo ngokuthi "izibani ze-dimmer ze-LED." Yiluphi uhlobo lwezibani, futhi kungani udinga idivaysi enjenge "dimmer"? Kulesi sihloko sizozama ukuphendula le mibuzo.

Ngaphambi kokuba siphendule umbuzo wezibani, siqala ngokucubungula ukuthi yini i-dimmer ngokwayo. Esemgodleni wayo, i-voltage regulator. I-Dimmer yezibane ze-LED ikuvumela ukuba ushintshe ngokushelela ukukhanya kwedivayisi enjalo. Inhloso yale divayisi ukuvula nokukhanyisa, futhi-ke, ukulawula ukuqina kwayo. Abalawuli abahlukahlukene bayatholakala emotweni yokuziphakamisa. Kulula ukuthenga i-dimmer yezibane ze-LED 220v, kanye nama-volts angu-12 noma angu-24. Manje ake sihambe ngqo ezikhanyeni. "Izibani ze-dimmer ze-LED" - kungani lezi zimveliso zibizwa kanjalo?

Iqiniso liwukuthi kunezinsiza eziningi zokukhanyisa ze-semiconductor. Zihlukile ngesimo, ubukhulu bezinyawo, injongo, amandla, ukukhanya nezinye izilinganiso. Kodwa bambalwa kakhulu abantu abazi ukuthi akuzona zonke izibani ezingasetshenziswa nge-dimmer. Iphuzu eliphelele ukuthi akuzona zonke amadivaysi e-LED aklanyelwe ukulawula ukukhanya, ngenxa yalokho, ukusebenzisa imikhiqizo enjalo nge-voltage regulator kungabangela ukuthi ngeke basebenze kwimodi edingekayo futhi bangase bahluleke, futhi umthengisi noma umkhiqizi uzovele enqabe Wena enkonzweni yesiqinisekiso. Ngakho-ke, uma uhlose ukufaka ama-voltage regulators ekamelweni, noma kakade umile, kuzomele uthenge izibani ze-LED ze-dimmer.

Kukhona ukukhethwa okukhulu kwezibani ezenzelwe ukusebenza nezilawuli zombane. Into esemqoka uma uthenga izibani ezinjalo ukucabangela umthwalo omncane wesilawuli sakho, isibonelo, amadivaysi amaningi ajwayelekile anenani laleli phakamitha - 20-45 W. Uma usebenzisa isibani se-incandescent kuso , khona-ke ngeke kube khona izinkinga, kodwa izibani ze-dimmer ze-LED zivame ukuba namandla ngaphansi kwalesi silinganiso. Esimweni esinjalo, kubalulekile ukusebenzisa izibani eziningana nge-regulator eyodwa, ukuze amandla abo aphelele adlule le parameter. Futhi kubalulekile ukucabangela ukusetshenziswa okungaphezulu kwezibani nge-one voltage regulator. Kukhona indlela elula yokuthola isibalo sezibani ze-LED nge-dimmer. Ihluke endleleni yokuthola izibani ze-incandescent. Uma kwenzeka izibani ze- incandescent, amandla amakhulu okuphakamisa omlawuli ahlukaniswe amandla wezibani, futhi ngenxa yalokho sinamabhomu amaningi. Ngokukhanyisa kwe-LED, lokhu kubalwa akukwazi ukusetshenziswa. Ukuze ugweme ukwehluleka kwezibani ze- LED, kunconywa ukuba unqume inani lamathuluzi nge-dimmer ngokusebenzisa amaphepha obuchwepheshe kusuka kumenzi.
