DALI sawv cev rau Digital Addressable Lighting Interface. Vim tias nws yog tsim los rau kev tsim vaj tsev thiab kev lag luam teeb pom kev zoo, nws tau teeb tsa cov qauv siab rau lub ntiaj teb digital teeb pom kev zoo. Tsis tas li ntawd, DALI hloov pauv tau nrog ntau hom khoom siv. Nrog rau ib qho kev sib txuas, koj tuaj yeem siv hluav taws xob tswj tag nrho cov teeb pom kev zoo thoob plaws hauv lub tsev lag luam.
DALI teeb pom kev zoo tswj qhov system yooj yim rau nruab, uas txhais tau tias koj lub lag luam tuaj yeem txo qis sijhawm. Tsis tas li ntawd, qhov tseeb tias kev teeb tsa raug nqi tsawg dua los ntawm kev xav tau lub sijhawm ua haujlwm tsawg thiab cov neeg ua haujlwm cov nyiaj ua haujlwm los ua kom tiav qhov kev teeb tsa thiab xav tau cov kab hluav taws xob yooj yim.
DALI system muaj ntau yam kev siv vim nws tuaj yeem hloov kho rau koj cov kev xav tau tshwj xeeb. Tsis muaj kev teeb tsa rau txhua qhov xwm txheej thiab lub tsev. Ib yam li ntawd, software configuration lossis reconfiguration yog ua tau yam tsis muaj rewiring lossis hard-wiring. Nws kuj yog sib xws nrog kev tswj vaj tsev.
Raws li tag nrho-digital system, DALI tuaj yeem muab kev txawj ntse sib faib yam tsis muaj kev hloov pauv sab nraud. Txog li 16 lub teeb pom kev zoo tuaj yeem khaws cia ntawm ib qho DALI kev khiav hauj lwm ntaus ntawv. Nrog rau kev ua haujlwm tsis siv neeg, koj tuaj yeem xaiv lwm yam kev xaiv, xws li sensor-tswj hloov thiab dimming.
Qhov zoo ntawm DALI:
Cov neeg siv muaj cov kev xaiv hauv qab no thaum txhim kho DALI ballasts hauv lawv lub teeb pom kev zoo:
• Yooj yim thaiv cov kab tswj (tsis muaj pawg tsim, tsis muaj polarity)
• Kev tswj hwm tus kheej (chaw nyob ntawm tus kheej) lossis pab pawg (chaw nyob hauv pab pawg) ua tau
• Kev tswj hwm ib txhij ntawm txhua chav nyob yog ua tau thaum twg los tau (ua-nyob rau hauv thawj zaug ua haujlwm muaj nuj nqi) los ntawm kev tshaj tawm xov xwm)
• Tsis muaj kev cuam tshuam ntawm kev sib txuas lus cov ntaub ntawv yuav tsum tau vim yog cov ntaub ntawv yooj yim
• Tswj ntaus ntawv raws li txoj cai (lub teeb txhaum, ....), (kev xaiv qhia: tag nrho / los ntawm pawg / los ntawm chav tsev)
• Tsis siv neeg tshawb nrhiav cov cuab yeej tswj
• Yooj yim tsim cov pab pawg los ntawm "flashing" teeb
• Tsis siv neeg thiab ib txhij dimming ntawm txhua chav nyob thaum xaiv ib qho chaw
• Logarithmic dimming tus cwj pwm – phim lub qhov muag rhiab heev
• Cov txheej txheem nrog kev txawj ntse (txhua chav tsev muaj cov ntaub ntawv hauv qab no: tus kheej chaw nyob, pab pawg ua haujlwm, teeb pom kev zoo, lub sijhawm ploj, ....)
• Kev ua haujlwm siab ntev ntawm cov teeb tuaj yeem khaws cia raws li qhov tseem ceeb (piv txwv li rau lub hom phiaj ntawm kev txuag hluav taws xob siab tshaj plaws tuaj yeem teeb tsa)
• Fading: kho qhov dimming ceev
• Kev txheeb xyuas hom tsev
• Cov kev xaiv rau teeb pom kev kub ceev tuaj yeem xaiv (xaiv cov ballasts tshwj xeeb, qib dimming)
• Tsis tas yuav hloov pauv / tawm sab nraud relay rau lub ntsiab voltage (qhov no yog ua los ntawm cov khoom siv hluav taws xob sab hauv)
