TRIAC Dimming, tseem hu ua theem-txiav lossis ua ntej- ntug dimming, yog ib txoj hauv kev siv dav dav hauv cov khoom siv hluav taws xob LED uas rov qab tag nrho- sib xws nrog cov tsoos TRIAC (Triode for Alternating Current) phab ntsa dimmers Ameslikas tsim rau cov teeb ci. Nws ua haujlwm los ntawm kev hlais qhov tseem ceeb ntawm AC sine yoj ntawm lub kaum sab xis sib txawv (feem ntau 0℃-180 degree), txo qhov RMS voltage xa mus rau tus tsav tsheb. Tus tsav tsheb LED lub voj voog sab hauv kuaj pom qhov sib tw waveform no, txhais lub kaum sab xis, thiab hloov kho cov zis tam sim no lossis PWM lub voj voog ua haujlwm kom dim cov LEDs zoo ntawm 100% mus rau qis li 5-10% brightness.
Hom no yog qhov zoo tagnrho rau cov tsev kho mob, tsev so, thiab cov chaw lag luam uas muaj cov kab hluav taws xob uas twb muaj lawm thiab TRIAC dimmer keyboards twb tau teeb tsa lawm - tsis tas yuav tsum muaj cov kav hlau txuas ntxiv. Qhov zoo muaj xws li tus nqi qis, simplicity, thiab broad compatibility nrog legacy infrastructure. Txawm li cas los xij, muaj kev sib tw: kev sib raug zoo tsis zoo tuaj yeem ua rau flickering, buzzing, los yog tsawg dimming ntau yam; qee tus neeg tsav tsheb xav tau qhov tsawg kawg nkaus load lossis tshwj xeeb "TRIAC-dimmable" circuitry kom ruaj khov. Nws kuj tsim EMI ntau dua li cov txheej txheem digital (0-10V lossis DALI).
Niaj hnub TRIAC-dimmable LED tsav tsheb suav nrog kev lim dej, sib sib zog nqus- dimming algorithms, thiab muag muag- pib nta kom txo cov teeb meem. Lawv yog qhov tsim nyog tshaj plaws rau cov uas tsis yog- tseem ceeb, nqi- cov ntawv thov nkag siab qhov twg yooj yim installation thiab universal dimmer kev txhawb nqa tseem ceeb tshaj qhov tseeb lossis flicker- ua haujlwm dawb ntawm qib qis heev.
