Nrog rau kev siv dav ntawm LED qhov muag teev, muaj qee qhov kev txhawj xeeb txog qhov ua rau muaj kev puas tsuaj ntawm lub teeb xiav lub teeb wavelengths tawm los ntawm LEDs. Ib qho ntawm qhov pom tseeb tshaj plaws thiab sib tham zoo ntawm lub teeb xiav yog nws lub peev xwm los cuam tshuam lub circadian atherosclerosis thiab li no qhov zoo ntawm kev pw tsaug zog.
Peb95 CRI, flicker -dawb qhov muag teevtau nrov heev nrog peb cov neeg siv khoom, thiab ib qho ntawm cov lus nug feem ntau yog yog tias lawv suav nrog lub teeb xiav thiab seb qhov ntsuas CRI siab puas muaj txiaj ntsig zoo rau kev txo qis.
Peb suav cov teeb pom kev zoo ntawm peb cov khoom thiab muab piv rau lawv qhov M / P piv qhov tseem ceeb rau cov neeg sib tw nrog cov xim qis dua kom pom tias lawv tau teeb tsa li cas.
M/P ratio yog dab tsi?
Qhov sib piv M / P, ib qho kev ntsuas tshiab, tau txais kev muaj koob meej raws li cov txheej txheem ua tau zoo los txiav txim siab seb lub teeb xiav lub teeb muaj pes tsawg lub teeb muaj. M / P sawv cev rau melanopic lux / photopic lux, thiab nws nrhiav kev ntsuas lub teeb ci lub peev xwm los cuam tshuam circadian rhythms. Hauv qhov tseem ceeb, qhov sib piv M / P yog qhov piv ntawm lub teeb lub zog uas txhawb kev ceeb toom (melanopic nkhaus) rau lub teeb lub zog uas ua rau lub siab kaj lug (photopic nkhaus).
Lub photopic nkhaus yuav zoo li nyuaj, tab sis nws yog tib lub nkhaus uas siv los xam cov luminous tso zis qhov tseem ceeb (lumens) uas txiav txim siab lub teeb ci. Zuag qhia tag nrho, ci ntsa iab yog "zoo" vim nws tso cai rau peb pom cov khoom pom, uas yog vim li cas peb xav tau qhov muag teev thawj zaug.
Lub melanopic nkhaus, ntawm qhov tod tes, muaj kev txhawj xeeb nrog qhov feem ntawm lub teeb xiav lub zog tam sim no nyob rau hauv lub teeb ci ntau dua li nws qhov ci ci tag nrho. Raws li qhov xav tau, qhov nkhaus no yog nyob ze ze rau lub teeb xiav lub zog wavelengths (saib daim duab hauv qab no, saib zoo los ntawm International WELL Building Institute's Excel Tool).
Xav txog qhov M / P piv rau qhov ntsuas ntawm "brightness lumens" vs "alertness lumens." Piv txwv li, M / P piv ntawm 0.50 qhia tias rau txhua txhua 100 brightness lumens tso tawm los ntawm lub teeb, 50 ceeb toom lumens raug tsim. Yog tias koj xav txo qis ntawm circadian cawv, qhov qis dua "kev ceeb toom lumens" yog qhov zoo dua, uas txhais tau tias qis dua M / P piv.
Vim li cas siab -CRI teeb muaj qhov cuam tshuam ntau dua circadian?
Koj puas xav tsis thoob los ntawm cov txiaj ntsig? Peb ib yam nkaus! Tom qab qhov piv txwv, peb xav tias siab CRI yuav zoo ib yam li qhov zoo los ntawm qhov pom kev pom, yog li peb yuav cia siab tias qhov siab CRI lub teeb yuav muaj txiaj ntsig zoo ntawm kev txo qis circadian cawv.
Txawm li cas los xij, nws hloov tawm tias qhov sib piv M / P tsis suav rau ib qho ntawm lub teeb ci xim rendering. Nws yog qhov tseem ceeb ntawm kev ua lej sib npaug uas cuam tshuam txog qhov ntau ntawm lub teeb lub zog tsim los ntawm kev ci ntsa iab rau qhov uas tsim los ntawm kev paub. Yog tias lub teeb pom kev zoo heev ntawm kev tsim lub teeb pom kev zoo tab sis tsim lub zog melanpic me ntsis, nws yuav muaj qhov tsawg M / P piv.
Los ntawm qhov kev xav no, peb qhov kev tshawb pom pib ua kom nkag siab ntau dua. Raws li peb tau tham yav dhau los, asiab CRI LEDtsis tshua muaj txiaj ntsig ntawm kev tsim kom pom qhov ci ci, nrog ib qho laj thawj tseem ceeb yog qhov siab CRI LED qhov chaw tso tawm lub teeb daj tsawg dua thiab ntau dua xiav, cyan, liab, thiab sib sib zog nqus - lub teeb liab.
Cov piv txwv hauv qab no yog exaggerated, tab sis nws qhia tau hais tias yuav ua li cas ib tug tsawg kawg nkaus CRI lub teeb qhov chaw yuav ua rau ib tug tsawg heev M / P piv. Cov duab hauv qab no piv rau 590 nm amber LED qhov chaw rau melanpic (xiav) thiab photopic (ntsuab) nkhaus. Feem ntau ntawm cov amber LED lub teeb lub zog poob rau ntawm daim duab nkhaus (ntsuab) thiab tsawg heev ntawm qhov nkhaus melanpic (xiav), uas ua rau muaj qhov tsis tshua muaj M / P piv ntawm 0.117.
Nws yuav tsum mus yam tsis tau hais tias amber LED muaj CRI qis thiab tsis tsim nyog rau kev teeb pom kev sab hauv. Txawm li cas los xij, vim tias nws qhov M / P piv qis heev, nws yuav yog ib txoj hauv kev zoo los txo cov teebmeem circadian. Intuitively, peb tuaj yeem lees paub qhov no los ntawm kev pom tias amber LED emits lub teeb lub zog me me nyob rau hauv cheeb tsam hauv qab ntawm melanopic (xiav) nkhaus.
Kev xav zaum kawg
High colour rendering thiab tag nrho spectrum teeb qhov chaw feem ntau txuas nrog kev noj qab haus huv zoo; Txawm li cas los xij, peb cov kev tshawb fawb pom tau hais tias lawv yuav muaj kev cuam tshuam ntau dua ntawm cov voj voog circadian dua li qis dua CRI teeb.
Nco ntsoov tias M / P piv kev nyeem ntawv muaj txiaj ntsig zoo, tab sis lwm yam tsis xws li lub sijhawm nruab hnub, qhov ze rau, thiab qhov ntev ntawm qhov raug rau lub teeb pom kev tuaj yeem muaj kev cuam tshuam ntau dua ntawm circadian rhythms.
