Xim kub yog qhov qhia pom ntau tshaj plaws ntawm qhov zoo ntawm lub teeb ci. Feem ntau hais los ntawm Tc. Xim kub yog txhais los ntawm lub cev dub kiag li. Niaj hnub no, LED teeb thiab teeb pom kev zoo muaj ntau yam hauv lub neej. Muaj ntau yam xim, yog li LED xim kub npaum li cas zoo rau qhov muag? Cov teeb coj teeb puas muaj teeb meem rau qhov muag? Don' tsis txhob txhawj, kuv yuav piav qhia rau koj hauv tib lub nroog hauv qab no, cia's saib.
LED xim kub npaum li cas yog qhov zoo rau lub qhov muag?
Muaj cov ntawv ceeb toom hais tias lub teeb txias txias LEDs thiab xiav LEDs muaj teeb meem rau lub qhov muag thiab yuav tsum raug txwv. Cov LEDs no feem ntau yog siv rau kev kho kom zoo nkauj, thiab qhov siv ntawm lub teeb xiav tawm los ntawm lawv deb tshaj li cov teeb pom kev zoo thiab cov teeb pom kev zoo ib txwm muaj. Cov teeb xiav xiav siab siv no yuav ua rau muaj kev puas tsuaj rau cov pigment epithelium ntawm retina thiab cov txheej txheem ntawm lub retina tib lub sijhawm, yog li ua kom cov retina aging thiab ua rau muaj kev pheej hmoo ntawm macular degeneration. Cov neeg raug tsim txom loj tshaj plaws ntawm LEDs yog cov menyuam yaus hnub nyoog qis dua 10 xyoo. Cov menyuam yaus hnub nyoog no tsis muaj qhov tsom iav lossis cov xim macular, yog li lawv tsis muaj peev xwm tiv taus lub teeb xiav.
Lub teeb LED siv lub teeb xiav thiab lwm cov xim daj phosphor sib tov los tsim lub teeb dawb, uas ua rau cov ntsiab lus ntawm lub teeb xiav hauv LED teeb kuj siab heev. Lub teeb xiav yog hais txog lub teeb xiav ntawm 400-500 nanometers. Yog tias qhov ci ntsa iab siab dhau lawm, qhov muag yuav ua rau muaj kev puas tsuaj rau lub retina tom qab saib ncaj qha ntawm lub teeb rau lub sijhawm ntev. Qhov kev phom sij ntawm lub teeb xiav yog nyob ntawm cov koob tshuaj xiav lub teeb uas tau txais los ntawm tib neeg lub qhov muag hauv qab lub teeb. Raws li kev cai hauv teb chaws, cov xim kub ntawm LED teeb pom kev tsis tuaj yeem siab dua 4000K. Txawm li cas los xij, vim lub teeb pom kev zoo thiab tus nqi qis ntawm cov xim kub siab LED teeb pom kev zoo, muaj ntau yam khoom kub xim kub ntawm lub khw.
Xim kub yog qhov taw qhia tshaj plaws ntawm lub teeb pom kev zoo spectral." Lub teeb sov" muaj xim kub tsawg, thaum" lub teeb txias" muaj xim kub kub. Tom qab xim kub nce, qhov kev faib ua feem ntawm xiav hluav taws xob nce, thiab lub teeb xiav nce raws li. Nyob rau tib lub sijhawm, qhov ci ntsa iab kuj cuam tshuam qhov feem ntawm lub teeb xiav. Feem ntau hais lus, cov teeb fluorescent thiab LED teeb nrog tib xim kub yog qhov tsis muaj teeb meem yog tias qhov ci ntsa iab tom kawg tsis ntau tshaj 3 npaug ntawm qhov qub. Txawm li cas los xij, rau ib tus neeg LED teeb uas ci dhau lawm, qhov feem pua ntawm lub teeb xiav tuaj yeem tshaj qhov muaj txiaj ntsig zoo. Raws li cov thev naus laus zis thev naus laus zis tau loj hlob, cov tuam txhab tsis tas yuav ua qhov muag tsis pom qhov kub thiab lub zog ntawm cov teeb kom ua tiav cov lumens siab, thiab ua kom pom tseeb txo qhov muaj peev xwm ntawm lub teeb xiav ntau dhau.
Cov teeb coj teeb puas muaj teeb meem rau qhov muag?
Thaum cov niam txiv xaiv lub qhov muag tiv thaiv teeb rau lawv cov menyuam, lawv feem ntau xav tias qhov ci ntsa iab, qhov zoo dua. Qhov no ua rau kuv nco txog zaj dab neeg thaum xyoo 1990 thaum peb xav tias cov hmoov nplej dawb, qhov zoo dua, tab sis tam sim no txhua tus paub tias kev ntxuav cov hmoov nplej yog vim qhov sib ntxiv ntawm cov hmoov nplej dawb. Brighteners yog teeb meem rau tib neeg. Yog li ntawd, txhawm rau txiav txim seb ib yam twg yog qhov zoo lossis qhov tsis zoo, ib tus yuav tsum paub nws cov ntsiab lus sab hauv kom paub meej.
Ntawm no kuv yuav tham txog cov kev paub yooj yim ntawm lub teeb ci. Lub teeb pom kev tiv thaiv lub qhov muag tiv thaiv lub qhov muag vim tias lub teeb hluav taws xob ntau zaus ua rau tib neeg tsis hnov qhov flicker ntawm fluorescence. Qhov no yog Philips thev naus laus zis hauv xyoo 1980, thiab tam sim no txhua lub tuam txhab loj thiab me tuaj yeem ua tau. Tus yuam sij rau kev tiv thaiv qhov muag yog xim rendering ntawm lub raj thiab xim kub ntawm lub teeb. Lub teeb tiv thaiv qhov muag siv lub raj fluorescent. Cov ntaub ntawv tseem ceeb luminescent tam sim no siv yog:
1. Pure peb-base toner,
2. Brine hmoov,
3. Sib tov hmoov ntawm ob.
Raws li tus nqi suav, lub qhov muag tiv thaiv teeb nrog tus nqi muag khoom tsawg dua 100 yuan nyob rau hauv kev ua lag luam yeej tsis tuaj yeem hu ua qhov muag tiv thaiv teeb, vim qhov muag tiv thaiv teeb uas tsis yog ntshiab tri-xim yog qhov muag pom teeb. Cov nyhuv ntawm qhov muag. (Tus nqi ntawm cov ntshiab tri-basic toner yog ze li ntawm 10 npaug ntawm cov hmoov halogen.) Kuv yuav tsis txheeb xyuas nws ntawm no. Kuv tsuas yog tham txog cov xim kub ntawm cov ntshiab tri-basic toner raj.
Lub teeb ntawm lub raj tri-xim yog phosphor yttrium oxide (lub teeb liab, peak wavelength yog 611nm) uas tuaj yeem tawm xim liab, ntsuab, thiab xiav lub teeb rhiab rau tib neeg lub qhov muag, thiab magnesium polyaluminate (lub teeb ntsuab, peak wavelength yog 541nm) ) Thiab barium magnesium polyaluminate (lub teeb emitting xiav lub teeb, ncov wavelength ntawm 450nm) nyob rau hauv ib tug tej yam kev faib ua feem tov rau hauv peb thawj xim phosphor, thiaj li yuav emit lub teeb ze rau hnub ci. Xim kub yog tib neeg lub qhov muag pom ntawm lub cev luminous lossis lub ntsej muag dawb. Feem ntau, los ntawm 10 tav su txog 2 teev tsaus ntuj, lub ntuj ntshiab thiab tsis muaj huab cua, thaum tsis muaj hnub ci ncaj qha, lub teeb nruab hnub yog li 5000--5500K. Tab sis lub teeb nyob rau lub sij hawm no yog cov tshuaj lom tshaj plaws thiab dazzling. (Saib qhov chaw uas lub teeb dawb nyob ze rau xiav hauv daim duab hauv qab no).
Lub teeb txuag hluav taws xob tam sim no feem ntau siv xim kub ntawm 5500-6500K, thiab qhov muag tiv thaiv teeb feem ntau siv xim kub ntawm 4500--5500K. Ntau tus ntawm peb cov neeg siv khoom hnov mob qhov muag tom qab nyeem ntawv hauv qab lub rooj teeb. Yog vim li cas yog qhov xim kub thiab xim rendering ntawm lub rooj teeb tsis zoo. Haum rau kev nyeem ntawv nyob ze. Nws yog ib qho yooj yim los sib piv tib phau ntawv nyob rau hauv lub teeb ntawm cov xim sib txawv. Qhov kub ntawm cov xim ntau dua, lub teeb ci dua, thiab qhov ntau dazzling lub teeb pom kev ntawm kev sau ntawv. Qhov qis xim kub, qhov sov dua lub teeb daj thiab softer lub teeb pom kev ntawm kev sau ntawv. , Qhov khaus tsawg dua rau qhov muag. Los ntawm kev sim, peb tuaj yeem pom tias cov txiaj ntsig ntawm kev nyeem phau ntawv yog qhov zoo tshaj plaws thaum cov xim kub nyob ib puag ncig 4000K, thiab tsis muaj qhov cuam tshuam tsis zoo. Thiab vim li cas tsuas yog ob peb lub tuam txhab siv 4000K xim kub teeb, tsuas muaj ob qho laj thawj: ib qho yog qhov siab dua cov xim kub ntawm lub teeb, qhov pheej yig dua, thiab qhov thib ob yog qhov siab dua cov xim kub, lub teeb ci dua. zoo li, ib yam li lub brightener. Zoo li hmoov nplej, zoo li zoo!
Yog li ntawd, nco ntsoov cov neeg siv ntawm lub rooj teeb thiab lub qhov muag tiv thaiv lub teeb uas lub teeb ci yog qhov zoo dua. Lub teeb rau kev nyeem ntawv thiab kev kawm yuav tsum yog mos. Tus qauv xim kub ntawm 3800--4200K yog qhov haum tshaj plaws.
Cov saum toj no yog cov lus piav qhia ntawm kev paub txog qhov kub npaum li cas LED xim zoo rau lub qhov muag thiab seb lub teeb LED puas muaj teeb meem rau lub qhov muag.
