TRIAC dimming thiab theem dimming feem ntau tsis meej pem raws li qhov qub, tab sis lawv yog ob txoj kev sib cais ntawm dimming lub teeb los yog LED. Kev nkag siab txog qhov sib txawv ntawm ob txoj hauv kev tuaj yeem pab koj xaiv qhov kev daws teeb meem dimming rau koj qhov xav tau teeb pom kev zoo.
TRIAC dimming yog ib hom kev coj-ntug theem dimming. Nws yog txoj hauv kev zoo tshaj plaws ntawm dimming rau qhov muag teeb thiab halogen, thiab nws kuj yog siv rau qee qhov muag teeb. TRIAC dimming thev naus laus zis tso siab rau TRIAC (triode alternating tam sim no) hloov los tswj cov nqi hluav taws xob uas ncav cuag lub teeb.
Theem dimming, ntawm qhov tod tes, suav nrog ob qho tib si ua-ntug thiab trailing-ntug dimming cov txheej txheem. Leading-edge theem dimming yog tib yam li TRIAC dimming, thaum trailing-ntug theem dimming yog ib tug tshiab technology uas feem ntau siv rau LED qhov muag teev. Trailing-ntug theem dimming siv MOSFET (hlau-oxide-semiconductor field-effect transistor) hloov los tswj qhov ntws ntawm tam sim no rau lub teeb. Txoj kev no muaj txiaj ntsig zoo dua li TRIAC dimming thiab yog qhov zoo tagnrho rau dimming LED qhov muag teev, vim nws txo cov suab nrov thiab flickering uas tuaj yeem tshwm sim nrog cov laus dua txoj kev dimming.
Yog li, TRIAC dimming tib yam li theem dimming? Cov lus teb tsis yog, tab sis TRIAC dimming yog hom theem dimming. Thaum tshawb nrhiav lub dimmer hloov, nws yog ib qho tseem ceeb kom paub tseeb tias nws yog sib xws nrog hom teeb uas koj siv (xws li incandescent, halogen, los yog LED).
Tsis tas li ntawd, nws yog ib qho tseem ceeb uas yuav tau xaiv lub dimmer hloov uas muaj peev xwm tuav tau cov wattage xav tau rau koj qhov teeb pom kev zoo.
Hauv cov ntsiab lus, TRIAC dimming yog ib hom kev coj-ntug theem dimming, thiab theem dimming kuj suav nrog trailing-ntug theem dimming. Ob txoj kev muaj lawv tus kheej cov txiaj ntsig thiab qhov tsis zoo thiab tuaj yeem siv rau ntau hom qij. Thaum xaiv lub dimmer hloov, nco ntsoov xav txog hom teeb uas koj siv thiab qhov siab tshaj plaws wattage ntawm koj lub teeb pom kev zoo.
