Hanyar Dimming na LED Luminaires - TRIAC & 0-10V

        Dimming LED yana nufin cewa haske, zafin launi, har ma da launi na fitilun LED suna canzawa. Fitilar dimming kawai zata iya jinkirin farawa da jinkiri, canza yanayin yanayin launi da haske bisa ga yanayin yanayi daban-daban. Kuma canza haske na iya canzawa cikin sauƙi. Tsarukan hasken wutar lantarki wani muhimmin sashi ne na tsarin gida mai wayo.

        Akwai galibi nau'ikan ka'idodin dimming guda huɗu don fitilun tushen LED a kasuwa, TRIAC, 0/1-10V, DALI, da DMX.

1)  TRIAC dimming (wasu kuma suna kiransa lokaci-yanke):

        Dimming na TRIAC ya haɗa da jagora - dimming baki da bin diddigi - dimming gefen.

        Ka'idar jagorar dimming baki ita ce canza ƙarfin shigar da ke cikin da'irar ta siginar TRIAC. Maɓalli a cikin kayan aikin TRIAC na iya daidaita ƙimar juriya ta ciki ta yadda za a iya canza igiyar igiyar wutar lantarki ta shigar da ita ta hanyar TRIAC, ta haka za ta canza ƙimar ƙarfin lantarki da daidaita hasken fitilar. Wannan hanyar dimming ƙaramin farashi ne, mai jituwa tare da da'irori da ke akwai, baya buƙatar sakewa, kuma yana da fa'idodin daidaitaccen daidaitawa, babban inganci, ƙaramin girma, nauyi, da sauƙin aiki mai nisa. Yana da babban kaso na kasuwa.

        Ka'idar trailing - dimming gefu ita ce kunna nan da nan bayan rabin - igiyar wutar lantarki ta AC ta fara kuma a kashe nan da nan lokacin da rabin - ƙarfin igiyar igiyar ruwa ta kai ƙimar saita don samun dimming. Idan aka kwatanta da jagora - dimming baki, trailing-dimming gefen ya fi dacewa da aiki da kwanciyar hankali tare da kayan aikin lantarki saboda babu ƙaramar abin da ake buƙata na yanzu.

        A zamanin yau a cikin kasuwar hasken wuta ta LED, samar da wutar lantarki sun dace da duka hanyoyin jagoranci - gefu da bin diddigi - baki.

2) 0/1-10V dimming:

        0-10V dimming hanya ce ta dimming analog. Shi ne don sarrafa abin da ake fitarwa na wutar lantarki ta hanyar canza ƙarfin lantarki na 0-10V don samun raguwa.

        Lokacin daidaita 0-10V dimmer zuwa 0V, na yanzu yana raguwa zuwa 0, kuma hasken hasken yana kashe (tare da aikin sauyawa). Lokacin saita 0-10V dimmer zuwa 10V, abin fitarwa na yanzu zai kai 100%, kuma haske kuma zai zama 100%.

        Ka'idar 1-10V da 0-10V iri ɗaya ce ta fasaha. Akwai bambanci daya kawai. Lokacin kunna ko kashe fitilar, ƙarfin lantarki da ake buƙata ya bambanta. 0-10V dimming yana nufin lokacin da ƙarfin lantarki ya yi ƙasa da 0.3v, hasken zai zama 0, amma idan ƙarfin lantarki ya kasance 0v, tashar shigarwa tana cikin yanayin jiran aiki. 1-10V yana nufin hasken fitilar shine 0 lokacin da ƙarfin lantarki yayi ƙasa da 0.6V.

        Fa'idodin hanyar dimming 0-10V sune aikace-aikace mai sauƙi, dacewa mai kyau, daidaitaccen madaidaici, da lanƙwasa mai santsi. Lalacewar ita ce wayoyi suna da rikitarwa, raguwar ƙarfin lantarki zai shafi ainihin ƙimar dimming, kuma wayoyi da yawa na iya haifar da raguwar ƙarfin lantarki lokacin shigar da fitilu da yawa kuma suna haifar da haske daban-daban.
