Dab tsi ntawm LED teeb pom kev zoo koj paub?
LED illumination muab kev xaiv rau xim, lub teeb emission, thiab siv, zoo li yuav ib lub gemstone. Koj yuav tsum xub txiav txim siab seb koj puas nyiam sov lossis txias illumination. Lub teeb sov sov feem ntau muaj lub teeb daj daj, thaum lub teeb pom kev txias yog qhov tseem ceeb rau nws cov xim xiav.
Cov teeb ci incandescent tsoos yog toasty vim tias lawv feem ntau muaj qhov muag kub, qhov LEDs feem ntau muaj qhov txias dua. Cov hauv qab no yog kev sib cais ntawm qhov kev hloov pauv hauv Kelvin kub:
2000–3000 Kelvin: Zoo tagnrho rau cov chav qhua thiab cov chaw nyob me me. Kub xim.
3000-4500 Kelvin: Zoo tagnrho rau tsev thiab chaw ua haujlwm. Txias thiab ntse xim.
4500 ntxiv rau Kelvin: Qhov zoo tshaj plaws rau kev siv lag luam. lub teeb ci ntsa iab heev uas ntau dhau rau tsev.
Koj yuav tsum tau coj cov xim Rendering Index (CRI), uas ntsuas qhov purity ntawm LED teeb, mus rau hauv tus account ntxiv rau Kelvin kub. CRI siv ntau yam ntawm 1 txog 100, raws li qhia hauv qab no:
Txoj hauv kev zoo tshaj plaws los piav qhia qhov no yog muab piv rau kev saib cov ntaub ntawv VHS thaum ub uas tau siv thiab ua phem rau lub sijhawm. Nws yog discernible, tab sis nws lacks clarity. Tsawg CRI qhov muag teev tsis tshua muaj, tab sis lawv tseem ceeb heev kom nco ntsoov.
80–90: Qhov no muaj qhov ntse thiab qhov tseeb ntawm cable TV. Cov koob no muaj ntau lub teeb.
90 ntxiv: A CRI ntawm 90 ntxiv yog sib npaug rau HDTV. Txhua yam yog meej-txiav thiab tsaug zog li nws tuaj yeem ua tau.
Qhov kawg tab sis tsis kawg, ntau yam lumens muaj rau LED teeb. Txhawm rau sib piv cov luminosity ntawm niaj hnub LED teeb pom kev zoo rau cov teeb pom kev zoo ntawm cov teeb pom kev zoo, cov teeb pom kev zoo yog ntsuas hauv lumens.
Nov yog cov ntsiab lus ceev ceev ntawm lumens rau watts, tab sis nco ntsoov tias nws tsis yog kev tshawb fawb meej thiab cov no tsuas yog kwv yees:
25 watt pa roj teeb sib npaug 375 lumen LED
40 watt gas teeb qhov chaw vs. 600 lumen LED
60 watt pa roj teeb sib npaug 900 lumen LED
75 watt roj teeb lub teeb vs. 1125 brightness LED
100 watt roj teeb lub teeb vs. 1600 brightness LED
Tom qab qhia koj txog qhov yuav tsum tau ua, cia peb tshuaj xyuas seb nws ua haujlwm li cas hauv kev muaj tiag. Los ntawm LedsMaster.com, Kuv tuaj yeem nrhiav pom qhov tsis txaus ntseeg ntawm Kelvin nplai.
Koj tuaj yeem pom muaj pes tsawg txoj kev xaiv rau LED teeb pom kev zoo thiab yuav ua li cas qee qhov kev hloov kho no tuaj yeem cuam tshuam rau ob qho tib si kev zoo nkauj thiab kev ua tau zoo ntawm txhua qhov chaw hauv koj lub tsev.
Cov ntsiab lus kawg xav txog
Qhov kawg tab sis tsis kawg, peb xav qhia ob lub tswv yim nrog koj: ib qho ntawm kev lag luam hluav taws xob thiab ib qho ntawm kev nyab xeeb. Koj cov fittings yuav tsum yog airtight thiab rwb thaiv tsev sib xws (IC), uas yog ob qho kev txiav txim siab loj.
Recessed teeb pom kev zoo fittings uas yog rwb thaiv tsev tsim tso cai rau installation ntawm lub tsev ntawm chav tsev nyob ze rau lub rwb thaiv tsev nyob rau hauv lub qab nthab los yog lub ru tsev ntawm koj lub tsev. Qhov no yog tshwj xeeb tshaj yog pab tau thaum kho qhov chaw thiab sim ntxiv cov teeb pom kev zoo rau qhov chaw uas tsis muaj ua ntej.
Txhawm rau tiv thaiv cov rwb thaiv tsev los ntawm kev sib cuag nrog lub teeb thiab vaj tsev yog tias koj tsis yuav IC fixtures, koj yuav tsum tsim lossis yuav cov npog ntxiv.
Ua kom lub cuab yeej yog hermetic yog lwm qhov kev xav. Ib qho tsis-airtight fixture koj tso rau hauv koj lub ru tsev tuaj yeem ua haujlwm zoo li lub chimney thiab cia huab cua sov tawm mus rau hauv loft.
Hauv kev sib piv rau kev ua raws li rwb thaiv tsev, qhov no tsis muaj kev pheej hmoo ntawm kev nyab xeeb, tab sis nws ua rau cov nyiaj txiag tsis zoo thiab ua rau tsis muaj zog siv. Yog tias koj lub teeb raug teeb tsa hauv qab ntawm thaj chaw nyob, qhov no yog qhov teeb meem tsis tshua pom tseeb, tab sis cov khoom siv airtight yog qhov tseem ceeb yog tias koj lub teeb raug teeb tsa hauv qab ntawm lub qab nthab.
Hmoov zoo rau koj thiab kuv, feem ntau ntawm lub teeb hom thiab cov qauv uas peb tau hais saum toj no suav nrog airtight kev tsim kho thiab IC kev ntsuas raws li tus qauv nta.
