Muaj pes tsawg lumens ua lub teeb LED yuav tsum tau hloov cov teeb ib txwm?
LEDs ua haujlwm li cas?
Tsis zoo li cov teeb pom kev zoo ib txwm muaj, LEDs tsis muaj filaments hauv cov cua sov kom ci lub teeb. Lub teeb LED muaj PN kev npaj ntawm ob sab assortment qhov twg ib sab muaj cov electrons zoo thiab lwm sab muaj qhov tsis zoo. Thaum cov tam sim no ntws ntawm cov sab hauv ib qho nyiaj ntawm qhov hluav taws xob, ob qho tib si tsub nqi ua ke los tso tawm lub zog hauv daim ntawv ntawm lub teeb. Yog li, lub teeb peb pom tawm ntawm lub teeb yog LED teeb.
Vim li cas LEDs tau pom zoo?
LEDs yog qhov kev xaiv teeb pom kev zoo uas muaj teeb pom kev zoo nrog ntau qhov txiaj ntsig zoo li kev txuag hluav taws xob, kev ua neej ntev, kev phooj ywg ib puag ncig, thiab ntau yam txiaj ntsig. Xaiv cov LEDs tshaj cov teeb pom kev zoo ib txwm muaj yog qhov kev xaiv zoo tshaj plaws los ua kom lawv tsis txhob tso cua sov ntau dhau thaum lub teeb ci, siv lub zog tsawg dua, muaj qhov sib npaug wattage txaus, thiab lwm yam. Txawm li cas los xij, LED qhov muag teev yog qhov kim tshaj li CFLs thiab cov teeb pom kev zoo lawv cov txiaj ntsig ua rau kev siv nyiaj tsim nyog.
Nrog ntau txoj kev xaiv muaj nyob rau hauv LED teeb, koj tuaj yeem xaiv cov qij no rau yuav luag txhua qhov chaw koj xav tau. Lub teeb pom kev zoo uas cov qij muab tau zoo heev thiab lub teeb muaj qhov ua tau zoo heev.
Cov lus siv nyob rau hauv LED teeb
Lumens yog dab tsi?
Lub teeb tso zis muaj peev xwm ntawm lub teeb yog hu ua lumens. Xyuas kom cov lumens ua ntej yuav ib lub noob yog ib qho yuav tsum tau. Koj yuav tsum xam seb muaj pes tsawg lub lumens tiag tiag xav tau rau koj qhov chaw, tom qab ntawd nrhiav qhov haum watt fixture.
Lub zog taw taws tswm ciab (Fc) yog dab tsi?
Lub SI chav tsev ntawm luminous siv lub npe hu ua ko taw tswm ciab. Kev ntsuas yog siv los ntsuas cov lumens uas ncav cuag qhov chaw ntawm ib chav tsev nrog ib qho teeb pom kev zoo.
Kelvin yog dab tsi?
Siv los ntsuas CTT (correlated color temperature) ntawm lub teeb, Kelvin yog chav tsev uas hais txog qhov kub thiab txias ntawm cov xim ntawm lub teeb. Nyob rau hauv cov nqe lus ntawm LED teeb, qhov xim kub muab rau koj ib tug meej lub tswv yim ntawm yuav ua li cas lub teeb xim yuav disperse nyob rau hauv ib puag ncig. Cov xim kub ntawm lub teeb yuav txawv ntawm ob peb qhov kub thiab txias.
2700K-3500K - Mos / sov dawb lub teeb
Lub teeb mos los yog sov dawb muaj lub ntsej muag daj.
3500K-4500K - Ntuj dawb
Ib qho ntxoov ntxoo dawb ntawm lub teeb tshwm los ntawm cov xim kub. Lub teeb muaj xim daj me ntsis.
5000K - Hnub ci dawb
Lub teeb emits ib xim xiav me ntsis nyob rau hauv ib tug nruab hnub nrig dawb xim kub ntau yam. Feem ntau siv tau rau qhov chaw sab nraum zoov dav dua, lub teeb tuaj yeem ua kom pom tseeb hauv cheeb tsam.
5500K - 6000K - Txias dawb
Qhov kev siv ntawm qhov ntxoov ntxoo xiav nyob rau hauv cov xim kub yog qhov sib piv ntau dua. Lub teeb tsis pom zoo rau tsev neeg lub hom phiaj vim nws yog kev lag luam tus qauv xim kub.
Qhov xim kub ntau dua ib lub teeb ci LED, qhov dav ntawm daim ntawv thov yuav tsum yog. Piv txwv li, qhov sov sov lub teeb kub yog qhov zoo tagnrho rau tsev neeg lub hom phiaj, tab sis lub hnub ci dawb los yog txias lub teeb kub yog nyiam rau kev siv sab nraum zoov xws li chaw nres tsheb, txoj kev, txoj kev, lub vaj, thiab lwm yam.
Cov xim kub nrov ntawm LED qhov chaw nres tsheb teeb thiab LED ncej teeb yog 5700K uas txaus los xa cov teeb pom kev ntawm nruab hnub nrig thiab cov ntsiab lus txias dawb lite.
CRI yog dab tsi?
CRI stands rau xim rendering Performance index uas qhia tau hais tias yuav ua li cas cov khoom tshwm nyob rau hauv tib neeg lub qhov muag nyob rau hauv lub xub ntiag ntawm lub teeb. Lub spectrum qhia txog qhov tshwm sim ntawm lub teeb thiab qhov teeb pom kev zoo npaum li cas tuaj yeem nthuav tawm cov khoom hauv lawv cov xim ntuj / tiag tiag.
LED chaw nres tsheb teeb thiab LED ncej teeb yog qee qhov teeb pom kev zoo sab nraum zoov uas yuav tsum tau ua kom pom kev siab. Yog li, lawv cov CRI yog qhov xav tau ntau dua vim nws ua kom lub teeb pom kev zoo thaum tsaus ntuj.
Lumen efficiency yog dab tsi?
Ntsuas nyob rau hauv Lumens ib Watt, lub lumen efficiency qhia tau hais tias zoo npaum li cas lub teeb yog dispersing nws illumination. Piv txwv li, luminous efficiency ntawm 100 Watt qhov muag teev uas muaj lub zog lumens ntawm 1500 lumens yuav yog 15 Lumens ib Watt (1500 / 100=15).
0-10v dimming yog dab tsi?
0-10v dimming yog ib qho uas ua kom ntseeg tau tias lub teeb LED muaj peev xwm ua tau raws li 3- kauj ruam dimming muaj nuj nqi. Hauv kev ua haujlwm no, koj tuaj yeem kho qhov ci ntawm lub teeb raws li koj nyiam thiab qhov chaw xav tau. Qhov dimming no tso cai rau koj txuag lub zog thiab txuag koj ntau.
Keeb kwm ntawm LEDs
LED yog dab tsi?
LED hais txog lub teeb emitting diodes. Cov no yog cov chips me me rau ntawm ib qho semiconductor strip los yog phaj uas tam sim no ntws mus rau glow cov chips me me los yog qhov muag teev.
Lub teeb emitting diode yog dab tsi?
Raws li tau piav qhia ua ntej, lub teeb emitting diodes yog cov qij me me ntawm lub semiconductor nti uas ci thaum tam sim no ntws los ntawm lawv. Vim lawv qhov xwm txheej zoo li diodes ntawm lub rooj tsav xwm hauv Circuit Court, lawv xav tau lub zog tsis tu ncua kom cia lub zog ac tam sim no hloov mus rau dc zog.
