Lub hauv paus ntsiab lus ua haujlwm ntawm TRIAC dimmer tuaj yeem nkag siab yooj yim raws li kev kho qhov ci ntawm lub teeb los ntawm kev tswj cov tam sim no hauv Circuit Court. TRIAC (Peb Terminal Bidirectional Thyristor) yog lub hauv paus tseem ceeb ntawm cov dimmer no, uas yog lub tshuab hluav taws xob semiconductor uas tuaj yeem hloov lub sijhawm ntawm kev coj ua hauv txhua lub voj voog ntawm AC lub zog, yog li tswj qhov loj ntawm qhov tam sim no dhau los ntawm lub teeb. Thaum lub sij hawm TRIAC conduction luv luv, lub teeb lub teeb tau txais tsawg dua tam sim no, ua rau lub teeb tsaus nti emissions; Ntawm qhov tsis sib xws, lub teeb ci dua.
Qhov zoo ntawm TRIAC dimming thev naus laus zis feem ntau yog tshwm sim hauv cov hauv qab no. Ua ntej, TRIAC dimmer yog tsim rau ntau hom kev thauj khoom, suav nrog cov teeb taws teeb, halogen teeb, thiab qee lub teeb ci LED, uas ua rau nws zoo heev rau cov teeb pom kev zoo qub. Qhov thib ob, TRIAC dimmer tau yooj yim ua tiav qhov dimming ntawm 0 mus rau 100%, muab cov neeg siv ntau yam kev xaiv ci ntsa iab. Tsis tas li ntawd, kev loj hlob thiab nrov ntawm TRIAC dimming thev naus laus zis tau ua rau nws tus nqi qis, ua rau nws xaiv kev lag luam rau cov neeg siv nrog cov peev nyiaj tsawg.
Txawm li cas los xij, TRIAC dimming tshuab kuj muaj qee qhov teeb meem. Vim yog cov yam ntxwv ntawm nws txoj haujlwm ua haujlwm, TRIAC dimmers tuaj yeem tsim suab nrov thiab flicker thaum lub sijhawm dimming, tshwj xeeb tshaj yog nyob rau hauv qhov chaw qis. Qhov no tej zaum yuav yog qhov tsis zoo rau ib puag ncig uas yuav tsum tau muaj teeb pom kev nyob ntsiag to lossis ruaj khov. Tsis tas li ntawd, nrog kev txhim kho sai ntawm LED teeb pom kev lag luam, qhov teeb meem kev sib raug zoo ntawm TRIAC dimmers thiab cov teeb pom kev zoo ntawm LED tshiab tau maj mam ua qhov tseem ceeb. Vim yog txoj kev ua haujlwm sib txawv ntawm LED teeb piv rau cov teeb pom kev zoo, siv TRIAC dimmers ncaj qha tuaj yeem ua rau xim sib txawv thiab qhov ci tsis sib xws.
Txhawm rau kov yeej cov kev cov nyom no, cov tuam txhab tsim khoom tau tsim cov kev daws teeb meem tshwj xeeb tsim rau LEDs, xws li PWM (Pulse Width Modulation) raws li lub tshuab dimming. PWM dimming ua tiav cov nyhuv dimming los ntawm kev tig ceev thiab tawm ntawm LED kom tswj qhov nruab nrab qhov ci. Txoj kev no tsis yog tsuas yog ua tiav lub suab nrov thiab flicker dawb dimming, tab sis kuj tswj cov xim sib xws thiab ruaj khov. Txawm li cas los xij, tus nqi ntawm PWM dimmers feem ntau yog siab dua TRIAC dimmers thiab tej zaum yuav xav tau rewiring, nce installation complexity thiab nqi.
TRIAC dimming tshuab ua tau zoo nyob rau hauv ntau yam, tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm compatibility thiab nqi-zoo. Txawm hais tias muaj qee qhov teeb meem, TRIAC dimmers tseem yog qhov kev xaiv zoo tshaj plaws rau ntau lub teeb pom kev zoo. Rau cov neeg siv uas ua raws li kev paub teeb pom kev zoo dua, PWM dimming lossis lwm yam kev daws teeb meem siab tshaj tuaj yeem txiav txim siab. Txawm hais tias qhov kev siv tshuab dimming yog xaiv, qhov tseem ceeb nyob rau hauv kev sib piv cov teeb pom kev zoo thiab cov peev txheej kom ua tiav cov teeb pom kev zoo thiab kev ua haujlwm ntawm lub zog.
