Puas yog LED teeb ua teeb meem mus tas li rau qhov muag? Peb puas tseem siv tau?
Recently, the topic "LED lights can cause permanent damage to the eyes" has appeared on Weibo, which has caused heated discussions and concerns among netizens.
Raws li Daily Mail, Fabkis cov tub ceev xwm saib xyuas kev noj qab haus huv tau hais tias LED teeb tuaj yeem ua rau lub retina puas tsuaj mus tas li thiab cuam tshuam peb txoj kev pw tsaug zog.
The French Food Environment and Occupational Health and Safety Agency (anses) issued a warning on May 14 that strong LED lights can cause "phototoxicity".
Tam sim no, LED teeb tau nkag mus rau hauv txhua yam ntawm peb lub neej niaj hnub. Raws li kev taw qhia ntawm lub zog-Txuag txoj cai thiab tshem tawm cov teeb pom kev zoo (cov teeb taws teeb thiab cov teeb pom kev zoo halogen) los ntawm kev ua lag luam teeb pom kev zoo, LEDs tau siv dav hauv kev qhia, kho kom zoo nkauj thiab teeb pom kev zoo vim lawv ua tau zoo lub zog ua haujlwm. Nws kuj yog siv dav hauv TV qhia.
In such a common application scenario of LED lights, how should we reasonably view the warning "LED lights will cause permanent damage to the eyes" put forward by relevant agencies? How should we use LED lights in our daily life?
Let's first look at the specifics of the anses report.
Cov teebmeem kev noj qab haus huv ntawm LEDs, feem ntau yog cov teebmeem ntawm lub teeb xiav ntawm lub qhov muag
Qhov tseeb, qhov yog li -hu ua kev noj qab haus huv ntawm cov teeb ci LED feem ntau yog los ntawm cov teebmeem ntawm lub teeb xiav ntawm ob lub qhov muag - uas tseem yog qhov tseem ceeb ntawm daim ntawv qhia anses.
Hais txog lub teeb xiav, ntau tus neeg tau hnov txog nws hauv lawv lub neej txhua hnub. Ntau lub lag luam yuav ua tiav lub hom phiaj kev lag luam ntawm kev lag luam los tiv thaiv- cov khoom siv lub teeb xiav los ntawm kev ua phem ntawm lub teeb xiav rau tib neeg kev noj qab haus huv, xws li tiv thaiv - tsom iav xiav, tiv thaiv -xiav xov tooj zaj duab xis, qhov muag tiv thaiv teeb thiab lwm yam. Hauv keeb kwm ntawm Lilac Garden, cov neeg nyeem feem ntau tawm cov lus, ua rau lawv tsis meej pem txog cov khoom siv los tiv thaiv - xiav.
Yog li, Blu-ray yog dab tsi? Nws ua mob rau tib neeg lub cev li cas?
Lub li-hu ua lub teeb xiav yog hais txog siab-lub zog luv-yoj lub teeb nrog lub wavelength ntawm 400 thiab 500 nm, uas yog ib feem ntawm lub teeb ntuj. Vim nws cov kev tshwj xeeb, LED tuaj yeem tawm lub teeb xiav hauv lub sijhawm luv luv, uas muaj lub teeb pom kev zoo dua li lwm qhov teeb pom kev zoo.
Rov qab rau xyoo 2010, Anses tau taw qhia tias lub teeb xiav hauv LEDs muaj tshuaj lom rau ntawm lub retina.
Daim ntawv tshaj tawm tshiab tshaj tawm los ntawm anses kuj tseem qhia meej tias txhua cov ntaub ntawv tshawb fawb tshiab tau txais txij li xyoo 2010 txhawb cov tshuaj lom ntawm lub teeb xiav ntawm lub qhov muag. Cov teebmeem tshuaj lom no suav nrog luv luv-cov teebmeem phototoxic cuam tshuam nrog kev raug mob hnyav, thiab ntev-cov teebmeem cuam tshuam nrog cov kis tau ntev, uas tuaj yeem ua rau tsis pom kev thiab muaj kev pheej hmoo ntawm hnub nyoog nce ntxiv-txog macular degeneration.
Tsis tas li ntawd, cov kws tshaj lij tau taw qhia tias kev raug teeb pom kev zoo nrog lub teeb xiav muaj zog thaum hmo ntuj tuaj yeem cuam tshuam lub moos lom neeg thiab cuam tshuam rau kev pw tsaug zog. Vim muaj kev hloov loj hauv lub teeb ci ntawm qee lub teeb ci LED, cov pab pawg rhiab xws li cov menyuam yaus thiab cov tub ntxhais hluas yuav muaj kev cuam tshuam ntau dua rau cov teebmeem ntawm qhov kev hloov lub teeb no, xws li mob taub hau thiab pom kev qaug zog.
Txawm li cas los xij, qhov no tsis tau txhais hais tias peb yuav tsum tso tseg tag nrho lub teeb xiav thiab nyob deb ntawm txhua yam khoom siv LED.
Lub teeb xiav muaj cov txiaj ntsig zoo, thiab nws cov kev phom sij kuj muaj kev nyab xeeb
Lub teeb xiav kuj muaj txiaj ntsig zoo rau tib neeg lub cev.
Lub teeb xiav nrog lub wavelength ntawm 455-500 nm tuaj yeem kho cov kab mob lom neeg, kev xav, thiab kev nco, thiab muaj lub luag haujlwm tseem ceeb hauv kev tsim qhov muag tsis pom kev thiab cuam tshuam rau kev txhim kho refractive.
Tsis tas li ntawd, kev phom sij ntawm lub teeb xiav tuaj yeem ntsuas.
Tam sim no, cov chaw tso cai, cov koom haum thiab cov kws tshaj lij hauv tsev thiab txawv teb chaws tau ua ntau yam kev ntsuam xyuas thiab kev ntsuam xyuas ntawm lub teeb xiav teeb pom kev zoo ntawm LEDs, thiab tau tsim cov qauv IEC62471 xiav lub teeb kev nyab xeeb. Cov qauv no siv tau rau txhua qhov chaw teeb pom kev tshwj tsis yog lasers thiab tau txais dav los ntawm ntau lub teb chaws.
According to the standard, all kinds of light sources can be classified into zero-type hazard (gazing time>10000s), thawj-chav phom sij (100s Tsawg dua lossis sib npaug rau lub sijhawm ntsia<10000s), second-class="" hazard=""><100s) and="" three-class="" hazard="" according="" to="" the="" fixation="" time="" (fixation="" time="" ≤="">
Tam sim no siv los ua LED teeb pom kev zoo, muaj qhov pib xoom thiab ib qho kev phom sij, uas zoo ib yam li lwm qhov chaw teeb pom kev zoo thiab tag nrho nyob rau hauv qhov chaw nyab xeeb.
Raws li kev soj ntsuam los ntawm Shanghai Lighting Product Quality Supervision and Inspection Station (2013.12), ntawm 27 LED cov qauv los ntawm ntau qhov chaw, 14 yog nyob rau hauv cov khoom tsis yog - phom sij thiab 13 yog thawj -chav kawm phom sij. Cov teeb pom kev zoo thiab teeb pom kev zoo no yog siv rau hauv txoj kev ib txwm muaj thiab tsis muaj teeb meem rau tib neeg lub qhov muag.
The anses report also pointed out that our commonly used "warm white" LED home lamps are no different from traditional lighting, and the risk of phototoxicity is very small.
Txawm li cas los xij, daim ntawv tshaj tawm kuj tseem hais ntxiv tias lwm yam teeb pom kev zoo ntawm LED, xws li teeb nyem, lub teeb lub tsheb, kho kom zoo nkauj lossis cov khoom ua si, tej zaum yuav nplua nuj nyob rau hauv lub teeb xiav, uas yog Class II txaus ntshai thiab tsis nyob rau hauv qhov chaw nyab xeeb, yog li qhov muag tsis tuaj yeem ntsia. .
Tsis tas li ntawd, lub khoos phis tawj, smartphone thiab ntsiav tshuaj cov ntxaij vab tshaus yog qhov tseem ceeb ntawm lub teeb xiav, thiab txij li cov menyuam yaus thiab cov hluas yog cov pab pawg rhiab tshwj xeeb uas nws lub qhov muag tsis tuaj yeem lim lub teeb xiav tag, lawv lub sijhawm tshuaj ntsuam yuav tsum txwv.
Pom qhov no, kuv ntseeg tias koj twb paub qhov txaus ntshai ntawm LED thiab xiav lub teeb.
Peb yuav ua li cas? cov lus qhia txog kev siv LED
Yuav kom txo tau qhov tsis zoo tshwm sim ntawm LED xiav lub teeb ntawm tib neeg lub cev, qee cov lus qhia tau muab los ntawm anses yog raws li hauv qab no.
Nws raug nquahu kom siv cov xim sov sov (xim kub hauv qab 3000K) teeb rau cov teeb pom kev hauv tsev;
Txhawm rau tiv thaiv kev cuam tshuam ntawm lub moos lom neeg, cov pej xeem, tshwj xeeb tshaj yog cov menyuam yaus, tau qhia kom txo lawv cov kev sib cuag nrog cov ntxaij vab tshaus LED (cov xov tooj ntawm tes, ntsiav tshuaj, khoos phis tawj, thiab lwm yam) thaum hmo ntuj thiab ua ntej yuav mus pw;
Txwv tag nrho cov khoom siv LED rau Class Zero thiab Class One Hazards ntawm Blue Light Safety Standard;
Txwv tsis pub siv lub teeb pom kev ntawm lub tsheb taub hau thaum ua kom muaj kev nyab xeeb ntawm txoj kev.
As for the anti-blue light glasses or anti-blue light screens commonly used by the public, Anses said it is not recommended. The agency emphasizes that the products' effects on the retina vary widely, and their effectiveness in maintaining circadian rhythms has not been proven.
Tag nrho hauv tag nrho, tsis tas yuav txhawj xeeb ntau dhau ntawm lub teeb xiav thiab LED khoom. Tus yuam sij rau kev tiv thaiv qhov muag yog nyob ntawm tus cwj pwm zoo ntawm qhov muag, zam kev nyeem ntawv ntev -, thiab ua kom muaj kev ua si sab nraum zoov txaus.
Benwei LED Tube teeb tsis muaj flicker, tuaj yeem tiv thaiv qhov muag, yog tias koj muaj lus nug, thov hu rau peb dawb.
