Thyristor dimming (TRIAC dimming) yog ib qho cuab yeej siv los ntawm cov tsoos incandescent teeb era. Txawm hais tias nws muaj kev sib raug zoo, nws muaj qhov tsis xws luag hauv LED era. Cov hauv qab no yog nws qhov tsis zoo thiab yog vim li cas:
1. Cov teeb meem kev sib raug zoo
Yuav tsum muaj ib qho kev tsav tsheb tshwj xeeb: cov teeb LED zoo tib yam tsis sib haum nrog thyristor dimmers. Kev yuam kom lawv sib phim yuav ua rau flickering, tsis muaj peev xwm dim, lossis puas rau lub voj voog.
Dimmer matching yog complex: qhov kev ua tau zoo ntawm thyristor dimmers ntawm ntau hom sib txawv heev, thiab "TRIAC dimmable LED teeb" yuav tsum tau xaiv, uas muaj ib tug siab mus sib hais thiab yuam kev nqi rau cov neeg siv.
2. Cov nyhuv dimming tsis zoo
Flickering ntawm qhov ci qis (thaum dim mus rau 20-30% yuav flicker): Thaum qhov ci ntsa iab raug hloov mus rau qis, vim tsis muaj kev saib xyuas tam sim no (qhov tam sim no xav tau los ntawm LED yog me dua li ntawm cov roj teeb), lub teeb hlaws yuav hloov mus rau thiab tawm tsis tu ncua, ua rau pom flicker.
Nonlinear brightness hloov: Lub dimming nkhaus tsis du, thiab tej zaum yuav muaj ib tug tam sim ntawd "dhia siab" ntawm brightening / darkening.
3. Zog efficiency thiab poob
Hluav taws xob pov tseg: Thyristors dim los ntawm kev txiav tawm AC waveform, thiab cov hluav taws xob tsis siv hluav taws xob hloov mus rau hauv tshav kub, uas tsis tshua muaj txiaj ntsig zoo li PWM lossis digital dimming.
Shorten LED lub neej: Tam sim no instability thiab tshav kub tsub zuj zuj yuav ua rau kom LED lub teeb lwj, tshwj xeeb tshaj yog tsawg-kawg tsav fais fab mov yog ntau raug rau kev puas tsuaj.
4. Lwm yam teeb meem
Lub suab nrov cuam tshuam: Tsis zoo thyristor dimmers yuav ua rau muaj - suab nrov zaus (xws li inductor hum).
Electromagnetic cuam tshuam (EMI): Waveform txiav tuaj yeem cuam tshuam nrog lwm yam khoom siv hluav taws xob (xws li suab, xov tooj cua).
Cov lus qhia scenario uas siv tau
Xaiv thyristor dimming ua tib zoo: tsuas yog tsim nyog rau cov xwm txheej uas ib txwm dimming keyboards tau teeb tsa thiab cov kab tsis kam hloov kho (xws li hloov cov teeb pom kev qub).
Cov kev xaiv uas nyiam:
PWM dimming: haum rau scenes uas yuav tsum tau siab rau dumming, xws li lub rooj teeb thiab tso saib backlights.
Ntse dimming: xws li Wi-Fi/Zigbee dimming , txhawb kev dimming stepless thiab tuaj yeem tswj tau nyob deb.
Cov neeg siv cov phiaj xwm teb
Hloov lub dimming system: hloov mus rau digital dimming (xws li DALI) lossis ntse teeb.
Xaiv lub siab- zoo tshaj lub teeb: Saib rau "TRIAC dimmable" qauv cim los ntawm hom (xws li qee cov khoom ntawm Philips thiab Osram, BENWEI).
Nruab ib lub decoder: Nruab ib lub TRIAC-LED decoding module nyob rau hauv pem hauv ntej ntawm lub teeb los txhim kho kev sib raug zoo (tus nqi siab dua).
Thyristor dimming yog ib qho kev siv thev naus laus zis hauv LED era. Tshwj tsis yog tias muaj peev nyiaj lossis tej yam kev mob, nws raug pom zoo kom hloov mus rau qhov kev daws teeb meem ntau dua, koj tuaj yeem sab laj DALI dimmable thiab 0-10V dimmable ntawmhttp://www.benweilight.com
