Raws li incandescent thiab CFL teeb pom kev zoo hloov pauv tau hloov pauv, LED teeb tau hloov pauv sai sai raws li kev lag luam tus qauv rau ntau daim ntawv thov thiab tau hloov pauv tag nrho hauv ntau qhov chaw.
Txawm hais tias qhov tseeb tias LEDs siv lub zog tsawg dua, muaj zog dua, thiab yog li zoo dua rau ib puag ncig, me ntsis hais txog tib neeg thiab cov neeg siv khoom, tshwj xeeb tshaj yog thaum nws los txog rau kev nyab xeeb thiab kev noj qab haus huv ntawm lub teeb nws tus kheej.
Raws li piv rau cov teeb pom kev zoo thiab cov teeb fluorescent, LEDs feem ntau ua tau zoo li lossis zoo dua ntawm cov teeb meem hluav taws xob thiab teeb meem. Txhawm rau txo qhov txaus ntshai ntawm hluav taws thiab hluav taws xob poob siab, feem ntau ntawm cov kev tswj hwm lub cev tau txuas ntxiv hloov kho cov kev tsim kho tam sim no thiab cov cai tswj kev nyab xeeb. Tau kawg, nws yog ib lub tswv yim zoo los xyaum kev nyab xeeb hauv hluav taws xob.
Txawm li cas los xij, tsis tshua muaj kev paub lossis kev taw qhia txog qhov xwm txheej thiab kev ruaj ntseg ntawm lub teeb uas tsim los ntawm LED teeb. Cov teebmeem kev noj qab haus huv ntawm LED lub teeb, tshwj xeeb yog "xiav lub teeb" raws li nws cuam tshuam rau LED spectrum, nrog rau kev cuam tshuam ntawm LED teeb 'flicker feem ntau tau tham hauv tsab xov xwm no.
LED Teeb nrog Blue Light Risk
Txawm tias muaj tseeb hais tias LED qhov muag teev tsis tsim lub teeb ultraviolet, "xiav lub teeb" tau dhau los ua ib qho ntawm feem ntau hais txog kev phom sij thiab kev txhawj xeeb cuam tshuam nrog LED teeb pom kev zoo thiab cov lus qhia uas siv LED backlights nyob rau xyoo tas los no (smartphones, ntsiav tshuaj, TVs, thiab lwm yam) .
Melanopsin, lub qhov muag tshuaj hormones uas txhawb kev ceeb toom, paub tias yuav ua rau tib neeg lub qhov muag tau yooj yim dua los teb rau lub teeb xiav.
Muaj ntau lub teeb xiav nyob rau nruab hnub nrig, thiab nws ntseeg tau tias melanopsin pab peb tswj peb cov circadian rhythms thaum hnub pib thiab peb raug tshav ntuj.
Daim duab 1: Daim duab qhia cov lus teb melanopsin qhov rhiab heev nkhaus. Qhov no wavelength ntau ntawm lub teeb lub zog txhawb kev mloog.
Qhov teeb meem yog tias kev siv ntau dhau thaum yav tsaus ntuj yuav ua rau peb lub cev txuas ntxiv tsim cov melanopsin, ua rau nws nyuaj rau pw tsaug zog. LED teeb thiab peb cov khoom siv muaj ntau lub teeb xiav (txawm hais tias muaj cov ntsiab lus tseem ceeb thiab kev tsim nyog - saib hauv qab).
Peb lub cev ib txwm cia siab tias lub teeb xiav yuav txo qis thaum yav tsaus ntuj, tab sis los ntawm kev siv cov khoom siv LED uas tawm ntau lub teeb xiav, peb cuam tshuam peb lub cev 'lub moos lom neeg.
Yog li, puas yog lub teeb xiav emissions los ntawm LED teeb teeb teeb meem? Qhov tseeb tiag, txawm li cas los xij, ntau qhov kev hloov pauv yuav txiav txim siab tias qhov phom sij loj npaum li cas:
Lub teeb ci LED: Zaum ze rau lub teeb yuav ua rau koj pom lub teeb xiav ntau dua li ua tib yam thaum zaum ntxiv.
Ntev npaum li cas koj raug rau lub teeb LED rau; ntev lub teeb xiav tam sim no, qhov ua rau melanopsin ntau dua.
Lub sijhawm meej uas koj siv lub teeb LED tseem ceeb heev; raug thaum yav tsaus ntuj muaj kev pheej hmoo tsawg dua li raug thaum yav tsaus ntuj, ua ntej pw.
Qhov kev faib ua feem ntawm lub teeb xiav nyob rau hauv LED lub teeb lub spectrum yuav txawv nyob ntawm seb hom LED koj xaiv, xim kub, CRI, thiab lub teeb spectrum. Yog xav paub ntxiv, saib M/P ratio.
Thawj peb ntawm cov lus hais saum toj no yog qhov piav qhia tus kheej, thiab koj tuaj yeem txo koj qhov cuam tshuam rau lub teeb xiav los ntawm kev ua raws li cov haujlwm yooj yim no. Tej zaum koj yuav xav xaiv lub teeb teeb ua nrog circadian kev noj qab haus huv hauv siab thaum xaiv qhov zoo tshaj plaws ntawm LED teeb siv thaum hmo ntuj.
Feem ntau, koj yuav tsum tshawb nrhiav lub teeb uas muaj feem ntau dua ntawm lub zog liab thiab qis dua ntawm lub zog xiav hauv lawv cov teeb pom kev zoo. Cov tswm ciab thiab nplaim taws tso tawm ntau lub zog liab (ntev wavelength), uas tsis cuam tshuam nrog circadian rhythms thiab yog ib hom "teeb" uas peb lub cev tau siv thaum hmo ntuj.
Tej zaum koj yuav xav xav txog cov hauv qab no:
Xaiv lub teeb teeb nrog 2700K lossis qis xim kub, qhov zoo tshaj 2400K. Thaum lub npe raug rau cov qij no yog "sov dawb," paub qhov tseeb xim kub yuav xav tau. Tsis txhob siv cov teeb ci LED ntau dua 3000K thiab / lossis cov lus piav qhia "ci dawb," "ntxhiab dawb," "txias dawb," lossis "hnub dawb" vim lawv feem ntau yuav muaj lub suab nrov, ci ntsa iab. Lub teeb ci LEDs no muaj feem pua ntawm cov teeb xiav xiav hauv lawv cov spectrum.
Xaiv lub teeb ci nrog CRI siab. CRI siab dua txhais tau tias tsawg dua lub teeb xiav thiab ntau dua lub teeb liab, tag nrho lwm yam sib npaug. Piv txwv li, ib lub teeb LED nrog lub siab dua CRI, piv txwv li, yuav muaj zog liab ntau dua thiab tsawg dua lub zog xiav rau tib lub teeb 2700K.
Saib rau M / P piv, uas qhia koj ntau npaum li cas lub teeb xiav tam sim no nyob rau hauv lub teeb lub spectrum piv rau lwm yam xim, yog tias cov chaw tsim khoom muab nws. Txhawm rau txo qhov pom ntawm lub teeb xiav, xaiv qhov muag teev nrog M / P piv ntawm 0.4 lossis qis dua.
Yog li, LED qhov muag teev puas muaj kev nyab xeeb thiab puas lub teeb xiav uas lawv emit cuam tshuam koj kev noj qab haus huv? Lawv ua, qhov tseeb, tab sis cov kev phom sij thiab kev txhawj xeeb tsuas yog cuam tshuam ntau dhau ntawm lub teeb xiav thaum yav tsaus ntuj, thiab lawv tswj tau. Caffeine yog piv rau lub teeb xiav, yog li tib lub siab xav ntsuas kev nyab xeeb yuav tsum tau ua raws. Ib teev ua ntej yuav mus pw, piv txwv li, koj yuav tsis xav kom txhaj tshuaj espresso ob zaug!
Daim duab 2: Daim duab qhia qhov txawv ntawm cov xim kub. Cov xim sov sov (hauv qab 2700K) yog qhov zoo tshaj plaws los txhawb kev so thiab so.
Koj tuaj yeem muaj kev nyab xeeb suav nrog LED teeb hauv koj lub tsev yam tsis muaj kev phom sij rau kev noj qab haus huv ntawm "kev nyab xeeb xiav" los ntawm kev ua tib zoo saib xyuas cov teeb pom kev zoo ntawm LED, ua raws li kev ntsuas tsim nyog, thiab siv qee qhov kev nkag siab zoo.
