Trailing edge dimmers muaj qhov qis qis qis dua li ntawm ntug kev, ua rau lawv zoo dua rau lub zog LEDs. Txoj cai 10% yog qhov tseem ceeb heev thaum siv trailing edge dimmers nrog LEDs. … Qhov txiaj ntsig tseem ceeb ntawm kev taug qab ntug dimmers yog qhov lawv muaj peev xwm tswj tau qis dua wattage loads
Dab tsi yog qhov sib txawv ntawm ntug ntug thiab ua ntug dimmer?
Leading edge dimming txiav ntawm ntug ntug ntawm txhua qhov nthwv dej 'ib nrab voj voog. Conversely trailing ntug dimming txiav tawm ib nrab thib ob ntawm txhua nthwv dej 'ib nrab voj voog. Trailing ntug dimmers tam sim no nrov dua ntawm ob hom.
Dab tsi yog txoj kab ntug dimming?
Trailing Edge Dimming (electronic dimming) siv cov tam sim no uas tau muab tua thaum AC waveform xaus, ua ntej nws hla xoomHom dimming no feem ntau yog siv nrog cov tsav tsheb hluav taws xob, thiab tsis ua rau muaj hluav taws xob nrawm (thiab tig, maj nrawm ntawm tam sim no) mus rau lub teeb ci.
trailing ntug dimmers ua haujlwm li cas?
Trailing edge dimmers ua haujlwm by txiav qhov thib ob ntawm txhua lub voj voog ib nrab hauv AC yojELV (Electronic Low Voltage) dimmers yog dimmers uas nyiam ua haujlwm nrog feem ntau dimmable LEDs. Trailing Edge Dimmers yog ELV dimmers. MLV (Magnetic Low Voltage) dimmers yog tsim los siv nrog cov tsav tsheb sib nqus.
Puas yog LED qhov muag teev ua ntug lossis ntug ntug?
Leading-ntug: inductive loads (xws li magnetic low voltage transformers), resistive loads (xws li incandescent). Trailing-edge: capacitive loads (xws li hluav taws xob hluav taws xob tsawg voltage transformers, LED tsav tsheb), resistive loads (xws li incandescent).
