TRIAC dimmer yog ib hom dimmer, tab sis nws puas yog dimmer li niaj zaus? Cov lus teb yuav nyob ntawm seb koj txhais li cas "tsis tu ncua" dimmer.
Ua ntej tshaj plaws, cia peb qhia meej tias lub dimmer yog dab tsi. Lub dimmer yog ib qho khoom siv uas tso cai rau koj los tswj qhov ci ntawm lub teeb ci, feem ntau yog los ntawm kev kho cov hluav taws xob hluav taws xob xa mus rau nws. Qhov no feem ntau yog ua tiav los ntawm kev siv qhov sib txawv tsis sib xws lossis thyristor-based mechanism.
Tam sim no, rov qab mus rau lo lus nug ntawm seb TRIAC dimmer puas yog dimmer li niaj zaus. A TRIAC (luv luv rau TRIode rau Hloov Tam Sim No) yog hom thyristor uas feem ntau siv hauv dimmer circuits. Nws ua haujlwm los ntawm kev tswj cov nqi tam sim no uas ntws los ntawm kev thauj khoom (xws li lub teeb pom kev zoo lossis LED) los ntawm kev qhib thiab tawm ntawm lub sijhawm tshwj xeeb thaum lub voj voog AC.
Piv rau lwm hom dimmers, xws li rheostats lossis capacitor-based dimmers, TRIAC dimmers muaj qee qhov zoo. Lawv ua tau zoo dua, txhim khu kev qha, thiab tuaj yeem ua haujlwm ntau dua lub zog. Lawv kuj tau siv dav hauv cov teeb pom kev zoo niaj hnub thiab tuaj yeem yooj yim nrog lwm cov kev tswj hwm, xws li cov khoom siv hauv tsev ntse.
Txawm li cas los xij, TRIAC dimmers kuj muaj qee qhov kev txwv. Lawv tuaj yeem ua rau flickering lossis buzzing hauv qee hom teeb, xws li CFLs lossis qee qhov LEDs. Lawv kuj tuaj yeem tsim hluav taws xob cuam tshuam (EMI) uas tuaj yeem cuam tshuam rau lwm yam khoom siv hluav taws xob nyob ib puag ncig.
Yog li, los teb cov lus nug thawj zaug, TRIAC dimmer yog hom dimmer, tab sis nws yuav tsis raug suav tias yog "tsis tu ncua" dimmer nyob rau hauv qhov kev txiav txim siab tias nws siv ib hom thyristor-based mechanism. Txawm li cas los xij, nws yog ib qho kev nyiam thiab siv tau zoo ntawm kev tswj cov teeb pom kev zoo thiab yog ib qho kev xaiv rau ob qho tib si hauv tsev thiab kev lag luam teeb pom kev zoo. Nws yog ib qho tseem ceeb los xaiv qhov tsim nyog dimmer raws li hom teeb pom kev zoo thiab lub teeb uas koj siv.
