LED kev lag luam yog lub teb chaws txoj kev lag luam tawm tswv yim, thiab LED lub teeb qhov chaw yog qhov zoo tshaj plaws lub teeb tshiab nyob rau hauv lub xyoo pua 21st, tab sis vim hais tias LED technology tseem nyob rau hauv txoj kev loj hlob ntawm kev loj hlob mus tas li, kev lag luam tseem muaj ntau cov lus nug txog nws lub teeb zoo. Cov yam ntxwv, daim ntawv no yuav muab cov kev xav nrog kev xyaum, txheeb xyuas qhov teeb meem tam sim no ntawm LED thiab kev txhim kho yav tom ntej, txhawb kev noj qab haus huv ntawm LED kev lag luam.

LED kev lag luam txoj kev loj hlob raws li txoj cai thiab tiam sis

a.Los ntawm qhov kev xav ntawm lub voj voog khoom, LED teeb pom kev zoo tau nkag mus rau lub sijhawm loj hlob.

Tam sim no, LED teeb pom kev zoo, txawm tias nyob rau sab nraum zoov teeb pom kev zoo, lossis chaw ua lag luam teeb pom kev zoo, tau nkag mus ntawm qhov ceeb toom.

Tab sis nyob rau theem no, lub teeb pom kev hauv tsev tuaj yeem piav qhia raws li lub hnab sib xyaw, cov khoom siv hluav taws xob tsis zoo, cov khoom siv teeb pom kev zoo LED tuaj yeem pom txhua qhov chaw.LED teeb pom kev zoo tseem daig hauv kev txuag hluav taws xob, kev tiv thaiv ib puag ncig thiab lub neej ntev ntawm lub teeb.Yog li ntawd, qhov no tseem ua rau feem ntau LED teeb pom kev lag luam mus nrhiav kev ua haujlwm siab luminous thiab kev sib tw nqi qis, thaum tsis quav ntsej LED rau tib neeg kev noj qab haus huv thiab kev nplij siab thiab ntse teeb pom kev zoo ntawm kev siv qib siab.

b.Qhov twg yog qhov kev taw qhia yav tom ntej ntawm LED kev lag luam?

Lub teeb pom kev zoo yuav txuas ntxiv mus nrog kev tsim kho thev naus laus zis, uas yog cov txheej txheem kev tsim khoom lag luam, nyob rau hauv lub sijhawm ntawm LED-coj teeb pom kev zoo, vim tias lub teeb ci muaj ntau yam plasticity, kev nrhiav lub teeb zoo kuj tseem txhim kho.

Los ntawm tag nrho cov kev xav, LED kev lag luam yog tam sim no nyob rau hauv ib tug qeeb txoj kev loj hlob theem, tsis muaj ib tug ntxiv technologies innovation ua rau kev lag luam koom nyob rau hauv tus nqi tsov rog, nyob rau hauv tus nqi tsov rog nce dawb-kub, yuam kev ua lag luam kom zoo, ntse thiab lwm yam. cov lus qhia.

Dab tsi yog "lub teeb" nrog qhov zoo?

Yav dhau los, LED teeb uas ci, ruaj khov luminous efficiency, thiab lwm yam, yog lub teeb zoo.Niaj hnub no, nrog lub tswv yim ntawm teeb pom kev zoo ntsuab thiab tob tob hauv tib neeg lub siab, tus qauv ntawm lub ntsiab lus ntawm lub teeb pom kev zoo tau hloov pauv.

a.Cov theem ntawm kev yeej los ntawm qhov ntau tau dhau mus, thiab lub sijhawm ntawm kev yeej los ntawm qhov zoo tau tuaj.

Thaum peb ua haujlwm rau North American cov neeg siv khoom, peb pom tias lawv cov kev xav tau rau LED teeb pom kev zoo tau nce siab dua thiab siab dua.Lub North American Lighting Commission IES tau qhia meej txog txoj kev ntsuas tshiab TM-30 rau cov xim rendering peev xwm ntawm lub teeb pom kev zoo, tshaj tawm ob qhov kev ntsuam xyuas tshiab Rf thiab Rg, uas qhia tag nrho tias cov neeg sib tw thoob ntiaj teb tau thawb mus rau kev tshawb fawb lub teeb ntawm LED.Blue King yuav nthuav qhia cov kev ntsuam xyuas no sai sai rau hauv Suav teb, kom cov neeg ntawm Tuam Tshoj tuaj yeem txaus siab rau qhov zoo dua LED teeb qhov chaw.

TM-30 piv 99 xim qauv, sawv cev rau ntau yam xim uas tuaj yeem pom hauv lub neej (los ntawm saturated mus rau unsaturated, los ntawm lub teeb mus rau tsaus).

TM-30 colorimetric daim duab

b.Tsuas yog kev nrhiav lub teeb pom kev zoo LED teeb pom kev zoo tuaj yeem coj kev nplij siab rau cov neeg siv.

Cov khoom lag luam zoo LED teeb pom kev zoo vim yog kev tsom mus rau kev noj qab haus huv, kev ua haujlwm siab, cov teeb pom kev zoo tiag tiag, rau cov khoom sib txawv xaiv cov xim zoo, thiab cov teeb pom kev zoo kom muaj kev tiv thaiv glare, tswj lub teeb xiav dej nyab xeeb, nrog cov tshuab ntse rau kev tswj teeb pom kev zoo, kom tau raws li kev nplua nuj thiab ntau yam kev txawj ntse tswj kev xav tau.

c.LED teeb pom kev zoo

Tsis zoo li cov luminaires ib txwm muaj qhov ua rau tsis ua haujlwm tam sim ntawd, LED luminaires feem ntau tsis poob sai sai.Nrog rau lub sijhawm ua haujlwm LED, yuav muaj teeb pom kev zoo.LM-80 xeem yog ib txoj hauv kev thiab qhov taw qhia los ntsuas lub lumen txij nkawm tus nqi ntawm LED teeb qhov chaw.

Los ntawm daim ntawv tshaj tawm LM-80, koj tuaj yeem npaj lub neej ntawm LED, hauv IES LM-80-08 tus qauv Rated Lumen Maintenance Life;L70 (teev): qhia tau hais tias lub teeb qhov chaw lumens lwj mus rau 70% ntawm thawj lumens siv sij hawm;L90 (teev): qhia tau hais tias lub teeb qhov chaw lumens lwj mus rau 90% ntawm thawj lumens siv sij hawm.

d.High xim rendering Performance index

Xim rendering Performance index yog ib txoj hauv kev tseem ceeb los ntsuas cov xim rendering ntawm lub teeb, thiab tseem yog ib qho tseem ceeb parameter ntsuas cov yam ntxwv xim ntawm cov khoom siv teeb pom kev zoo, qhia los ntawm Ra / CRI.

Ra, R9 thiab R15

Cov xim rendering Performance index Ra yog qhov nruab nrab ntawm R1 txog R8, thiab xim rendering Performance index CRI yog qhov nruab nrab ntawm RI-R14.Peb tsis tsuas yog xav txog cov xim rendering Performance index Ra, tab sis kuj xyuam xim rau qhov tshwj xeeb xim rendering Performance index R9 rau saturated liab, thiab tshwj xeeb xim rendering Performance index R9-R12 rau liab, daj, ntsuab thiab xiav saturated xim, peb ntseeg hais tias cov no indicators tiag tiag sawv cev rau qhov zoo LED lub teeb qhov chaw, thiab rau kev lag luam teeb pom kev zoo lub teeb qhov chaw, tsuas yog thaum cov ntsuas no muaj nuj nqis yuav lav lub siab xim rendering ntawm LED.

Feem ntau, tus nqi siab dua, qhov ze rau cov xim ntawm lub hnub ci, qhov ze dua rau nws cov xim qub, qhov khoom tau teeb pom kev zoo.LED teeb pom kev zoo nrog lub siab xim rendering Performance index feem ntau yog xaiv hauv kev lag luam teeb pom kev zoo.Cov khoom muab los ntawm Blue View feem ntau txais yuav CRI> 95 raws li cov neeg siv khoom xav tau, uas tuaj yeem kho cov xim ntawm cov khoom hauv lub teeb pom kev zoo, thiaj li ua tiav qhov zoo siab rau lub qhov muag thiab txhawb cov neeg lub siab xav mus yuav khoom.

e. Dazzling Teeb

Xyoo 1984, Lub Koom Haum Hluav Taws Xob Hluav Taws Xob ntawm North America tau txhais qhov ci ntsa iab raws li qhov kev xav ntawm kev ntxhov siab, tsis xis nyob lossis tsis pom kev ua haujlwm hauv qhov muag pom tshwm sim los ntawm kev teeb pom kev zoo uas ntau dua qhov muag tuaj yeem hloov mus.Raws li qhov tshwm sim, qhov ci ntsa iab tuaj yeem muab faib ua qhov tsis xis nyob glare, lub teeb ci ntsa iab thiab kev lom zem glare.

LED yog ib tug loj tus naj npawb ntawm cylindrical los yog spherical pob, vim lub luag hauj lwm ntawm convex lens, nws muaj ib tug muaj zog taw tes, luminous siv nrog txawv pob puab thiab siv nyob rau hauv lub angular kev taw qhia: nyob rau hauv lub qub kev taw qhia ntawm lub siab tshaj plaws lub teeb siv, lub kaum sab xis ntawm kev sib tshuam nrog lub dav hlau kab rov tav rau 90. thaum deviating los ntawm ib txwm coj ntawm txawv θ lub kaum sab xis, lub teeb siv kuj hloov.cov yam ntxwv ntawm lub teeb qhov chaw ntawm LED.Yog li ntawd cov yam ntxwv ntawm LED teeb pom kev zoo muaj qhov ci ntsa iab heev thiab teeb meem glare tshwm sim.Piv nrog rau cov teeb ci, cov teeb fluorescent, cov teeb hluav taws xob siab sodium thiab lwm cov teeb pom kev zoo, cov kev taw qhia fiber ntau ntawm LED teeb yog cov concentrated heev thiab ua rau muaj qhov tsis xis nyob.

f. Blue teeb phom sij

Nrog rau qhov muaj koob meej ntawm LED, LED xiav lub teeb teeb pom kev zoo lossis lub teeb xiav xiav tau dhau los ua qhov teeb meem uas txhua tus tib neeg yuav tsum tau ntsib thiab daws, thiab hauv kev lag luam luminaire tsis muaj qhov zam.

Cov txheej txheem tshiab EU dav dav luminaire tau teev tseg tias yog lub luminaire suav nrog LED, hlau halide teeb thiab qee qhov tshwj xeeb tungsten halogen teeb uas tsis tuaj yeem raug zam los ntawm kev ntsuas kev puas tsuaj rau lub qhov muag yuav tsum raug soj ntsuam raws li IEC / EN62778: 2012 "Photobiological kev nyab xeeb ntawm lub teeb ci thiab luminaires. Daim ntawv thov kev ntsuam xyuas kev raug mob lub teeb xiav ", thiab nws tsis tsim nyog siv cov teeb pom kev zoo nrog cov teeb meem xiav xiav ntau dua RG2.

Nyob rau hauv lub neej yav tom ntej, peb yuav pom ntau thiab ntau lub tuam txhab, tsis tsuas yog tsim LED teeb pom kev zoo cov khoom, thiab tsis tsom rau ib tug neeg tsis, tab sis muaj peev xwm xav txog yuav ua li cas los txhim kho lub teeb pom kev zoo raws li tus nqi saw ntawm ntau lawm mus rau tag nrho. realization ntawm kev thov.Nyob rau hauv tus txheej txheem ntawm kev kho dua tshiab, teeb pom kev zoo tsim muaj peev xwm, cov khoom customization muaj peev xwm, nrog rau kev tsim thiab txhim kho cov peev xwm teb sai, yog qhov kev sib tw uas cov tuam txhab yuav tsum tau ntsib.
