LED (lub teeb-emitting diode) teeb pom kev zoo tau maj mam hloov cov khoom siv teeb pom kev zoo xws li cov teeb pom kev zoo thiab lub zog-txuag teeb vim yog lub ntiaj teb nrov tshaj plaws ntawm ntsuab thiab lub zog-txuag lub tswv yim thiab kev nce qib ntawm cov teeb pom kev zoo. Nws yog dav siv nyob rau hauv ntau yam teeb pom kev zoo, nrog rau cov tsev, chaw ua lag luam, kev lag luam, thiab cov chaw sab nraum zoov, thiab tau dhau los ua tus qauv kev xaiv hauv kev lag luam teeb pom kev zoo tam sim no. Nrog nws cov txiaj ntsig zoo tshaj plaws ntawm cov teeb pom kev zoo, LED teeb pom kev zoo tshaj plaws hauv kev txuag hluav taws xob, kav ntev, kev tiv thaiv ib puag ncig, thiab kev tswj hwm. Qhov no tsis tsuas yog hloov pauv tib neeg lub teeb pom kev zoo xwb tab sis tseem txhawb nqa kev lag luam teeb pom kev zoo rau kev ua haujlwm siab, ntsuab, thiab kev txawj ntse.
Core technological zoo ntawm LED teeb pom kev zoo
(1) Zog-nrhiav tau zoo thiab ua tau zoo, txo qis kev siv hluav taws xob: LED teeb pom kev zoo siab photoelectric hloov dua siab tshiab, nrog luminous efficiency feem ntau ncav cuag 80-180 lm/W, thiab qee qhov siab-kawg cov khoom txawm ntau tshaj 200 lm/W, deb siab tshaj incandescent 13 / 5 lm / W (10{100 lm / w) zog- txuag teeb (60{16}}80 lm/W). Qhov no txhais tau hais tias, ntawm tib lub ci ci, LED teeb tsuas yog siv 1/10 ntawm lub zog ntawm cov teeb ci thiab 1/3 ntawm lub zog txuag hluav taws xob, uas ua rau muaj kev txuag hluav taws xob tseem ceeb hauv lub sijhawm ntev. Nws yog qhov tshwj xeeb tshaj yog tsim rau cov teeb pom kev loj hauv cheeb tsam hauv kev lag luam thiab kev lag luam, ua kom pom cov txiaj ntsig tseem ceeb ntawm kev txuag hluav taws xob.
(2) Lub neej ntev heev thiab tsis tshua muaj nqi kho: LED teeb siv lub teeb semiconductor-emitting cov ntsiab lus, tsis muaj filament lossis iav casing, ua rau cov qauv muaj zog uas tsis yooj yim puas. Lub neej ib txwm muaj peev xwm ncav cuag ntau dua 50,000 teev, thiab qee qhov khoom siab - zoo tuaj yeem tshaj 100,000 teev. Piv nrog rau qhov muag teev (nyob ib ncig ntawm 1000 teev) thiab lub zog- txuag qhov muag teev (nyob ib ncig ntawm 8000 teev), LED teeb muaj lub neej ntev 5-50 npaug ntev dua li cov teeb pom kev zoo, txo qhov zaus ntawm kev hloov lub teeb thiab txo tus nqi kho. Lawv yog tshwj xeeb tshaj yog haum rau high-altitude, tej thaj chaw deb qhov chaw uas lub teeb hloov yog nyuaj.
(3) Ntsuab thiab ib puag ncig tus phooj ywg, muaj kev nyab xeeb thiab tsis muaj kev phom sij zais: LED teeb tsis muaj tshuaj lom lossis tsis zoo xws li mercury thiab txhuas, thiab yuav tsis ua phem rau ib puag ncig tom qab pov tseg, ua raws li kev tiv thaiv ib puag ncig thoob ntiaj teb. Tsis tas li ntawd, LED teeb yog flicker-dawb thiab glare-dawb (qhov no tuaj yeem ua kom zoo dua los ntawm kev tsim kho qhov muag), muab lub teeb muag muag uas tiv thaiv qhov muag zoo, ua rau lawv tsim nyog rau tsev, tsev kawm ntawv, tsev kho mob, thiab lwm yam xwm txheej uas yuav tsum tau ua kom pom kev zoo siab. Tsis tas li ntawd, LED teeb pib sai sai, yuav tsum tsis muaj preheating thiab teeb pom kev zoo tam sim ntawd, thaum tsim hluav taws xob qis thaum lub sijhawm ua haujlwm, zam kev nyab xeeb ntawm kev kub siab - kub kub cuam tshuam nrog cov teeb ci ib txwm muaj.
(4) Kev tswj tau siab thiab hloov tau mus rau ntau yam kev xav tau: LED teeb pom kev tuaj yeem ua tiav qhov ci ci thiab hloov xim kub (2700K-}6500K). Qee cov khoom txhawb RGB puv xim hloov xim thiab kev sib txuas ntse (kev tswj chaw taws teeb, kev tswj lub ntsuas), thiab tuaj yeem hloov kho lub teeb pom kev zoo raws li qhov sib txawv thiab xav tau. Piv txwv li, hauv kev lag luam scenarios, qhov ci tuaj yeem hloov kho kom tau raws li cov kev xav tau ntawm kev lag luam, hauv cov xwm txheej hauv tsev, xim kub tuaj yeem hloov kho kom tsim tau huab cua, thiab nyob rau hauv qhov xwm txheej sab nraum zoov, nws tuaj yeem ua ke nrog kev ua haujlwm sensor kom ua tiav lub zog txuag. Nws adaptability deb tshaj ntawm cov teeb pom kev zoo ib txwm muaj.
Qhov tseem ceeb sib txawv ntawm LED teeb pom kev zoo thiab ib txwm teeb pom kev zoo
Tsob nroj incandescent qhov muag teev: siab zog noj, luv lifespan, tsawg luminous efficiency, yooj yim puas tungsten filaments, siab kub tiam, thiab glaring teeb; lawv tau maj mam raug txiav tawm thiab tsuas yog siv ib ntus hauv ob peb lub sijhawm.
Ib txwm muaj zog- txuag qhov muag teev: Thaum lub zog ntau dua -ntau dua li cov qij taws, lawv muaj cov tshuaj mercury lom, muaj lub neej nyob nruab nrab, pib qeeb- nce, thiab lub teeb pom kev zoo tom qab siv ntev -; lawv kuj muaj ib qho xim kub thiab tsis zoo controllability.
LED teeb pom kev zoo: Kev sib txuas ntawm plaub qhov zoo ntawm kev txuag hluav taws xob, kev ua neej ntev, kev ua phooj ywg ib puag ncig, thiab kev tswj hwm, LED teeb pom kev zoo tsis muaj cov tshuaj lom neeg, nthuav tawm lub teeb qeeb qeeb, pib sai - nce, hloov xim kub thiab ci, thiab haum rau ntau qhov xwm txheej. Nws yog qhov kev hloov zoo tshaj plaws rau cov teeb pom kev zoo ib txwm muaj thiab kev loj hlob tam sim no hauv kev lag luam teeb pom kev zoo.
Ntau yam kev siv thiab tus nqi ntawm LED teeb pom kev zoo
(1) Lub teeb pom kev hauv tsev: Haum rau txhua qhov chaw suav nrog chav nyob, chav pw, chav ua noj, thiab lub sam thiaj. Mos, qhov muag - lub teeb tus phooj ywg nrog cov xim hloov tau. Nws ua tau raws li qhov xav tau teeb pom kev zoo thaum tsim cov cua sib txawv hauv tsev, txuag hluav taws xob thiab txo cov nqi hluav taws xob hauv tsev.
(2) Lub teeb pom kev lag luam: Haum rau cov khw muag khoom, khw muag khoom, tsev so, tsev ua haujlwm, thiab lwm yam. Muaj kev ci ntsa iab thiab txuag hluav taws xob. Brightness thiab xim kub tuaj yeem hloov kho kom zoo dua qub, txuas ntxiv lub teeb pom kev zoo, thiab txo cov nqi khiav lag luam.
(3) Lub teeb pom kev lag luam thiab sab nraum zoov: Haum rau cov chaw tsim khoom, tsev khaws khoom, txoj kev hauv nroog, teeb pom kev hauv nroog, chaw nres tsheb, thiab lwm yam. Muaj qhov ci ntsa iab, ruaj, tsis muaj dej, thiab huab cua- tiv taus. Adaptable rau qhov hnyav sab nraum zoov ib puag ncig, txo cov nqi tu thiab ua kom pom kev nyab xeeb.
(4) Teeb pom kev zoo tshwj xeeb: Tsim nyog rau tsev kho mob, tsev kawm ntawv, chaw sim, cog qoob loo, thiab lwm yam. Flicker-dawb, glare- dawb, thiab teeb pom kev zoo. Ua tau raws li qhov xav tau ntawm cov teeb pom kev zoo ntawm cov xwm txheej tshwj xeeb (xws li cov teeb pom kev loj hlob thiab cov teeb pom kev kho mob tsis muaj duab ntxoov ntxoo).
Cov ntsiab lus tseem ceeb rau kev xaiv LED teeb pom kev zoo
Txawm hais tias LED teeb pom kev zoo muaj txiaj ntsig zoo, kev xaiv tsis raug tseem tuaj yeem cuam tshuam rau nws qhov kev ua tau zoo thiab lub neej ntev. Cov ntsiab lus tseem ceeb yog raws li hauv qab no:
(1) Tsom ntsoov rau luminous efficiency thiab xim rendering Performance index (CRI): luminous efficiency txiav txim siab zog efficiency; ua ntej cov khoom lag luam nrog lub teeb pom kev zoo siab dua lossis sib npaug ntawm 80 lm / W. Lub CRI txiav txim siab lub teeb tsim tawm raug; rau cov ntawv thov hauv tsev thiab kev lag luam, ua ntej cov khoom lag luam nrog CRI Ntau dua lossis sib npaug ntawm 80, thaum rau kev kho mob thiab tsim daim ntawv thov, xaiv cov khoom nrog CRI Ntau dua lossis sib npaug rau 90.
(2) Xaiv lub siab - tsav tsheb zoo: Tus tsav tsheb yog "lub siab" ntawm lub teeb LED. Lub siab - tsav tsheb zoo ua kom muaj kev ruaj ntseg, tsis txhob flickering thiab lub teeb tawg sai, thiab ua rau lub neej ntev. Tsis txhob xaiv pheej yig, qis - tsav tsheb zoo.
(3) Ua raws li daim ntawv thov scenario: Xaiv qhov tsim nyog ci, xim kub, thiab ntsuas dej tsis zoo raws li daim ntawv thov scenario. Piv txwv li, xaiv IP65 lossis siab dua qhov ntsuas dej tsis zoo rau kev siv sab nraum zoov, xim sov sov (2700K-3500K) rau chav pw hauv tsev, thiab xim kub nruab nrab (4000K-5000K) rau kev siv hauv chaw ua haujlwm.
(4) Xaiv cov npe nrov thiab cov chaw tsim khoom lag luam: Cov khoom lag luam los ntawm cov tuam txhab muaj npe tau lees paub hauv qhov zoo thiab muaj kev paub zoo tom qab- kev muag khoom thiab kev lav phib xaub. Tsis txhob xaiv cov khoom qis dua - cov khoom muaj nqi los ntawm cov tuam txhab tsim khoom tsis tsim nyog thiab txo cov kev tu ncua yav tom ntej.
Yog tias koj muaj lus nug txog kev xaiv, kev yuav khoom, lossis kev siv lub teeb pom kev zoo LED- lossis yog tias koj xav tau cov khoom lag luam kho kom haum thiab nqe nqe lus raws li koj qhov chaw tshwj xeeb (txawm yog thaj chaw, kev lag luam, lossis sab nraum zoov)- thov koj xav tiv tauj peb txhua lub sijhawm.
