一, Lub hauv paus ntsiab lus: Cov ntsiab lus spectral thiab cov peev txheej ntawm kev pheej hmoo
LED cog kev loj hlob teeb kev siv cov ntaub ntawv semiconductor zoo li Ingan / Gan xa tawm qee yam wavelengths ntawm lub teeb. Lawv txoj kev tsim kho pom yog nyob ntawm cov bands rhiab tshaj plaws rau cog cov photosynthesis, uas yog lub teeb liab (660NM) thiab xiav lub teeb (450nm). Qhov kev tswj hwm lub sijhawm no ua rau cog kev loj hlob deb dua, tab sis nws tseem los nrog ob qhov kev pheej hmoo loj:
Lub teeb xiav txaus ntshai: xiav lub teeb nrog lub wavelength ntawm 415-455 nm muaj ntau lub zog thiab tuaj yeem mus ncaj qha los ntawm retina thiab lens rau lub retina thiab lens mus rau retina thiab lens rau lub retina thiab lens rau lub retina thiab lens mus rau retina thiab lens rau lub retina thiab lens rau lub retina thiab lens mus rau lub retina thiab lens mus rau lub retina thiab lens mus rau retina thiab lens rau lub retina thiab lens rau lub retina thiab lens mus rau retina thiab lens rau lub retina thiab lens mus rau retina thiab lens rau lub retina thiab lens mus rau retina thiab lens rau lub retina thiab lens rau lub retina thiab lens mus rau retina thiab lens rau lub retina thiab lens rau lub retina thiab lens mus rau retina. Kev tshawb fawb tau ua los ntawm Kev Ua Haujlwm Thoob Ntiaj Teb ntawm Kev Ua Haujlwm Thoob Ntiaj Teb (CEE) qhia txog lub teeb ci siab yuav ua rau muaj kev phom sij epithelial ntawm kev pheej hmoo ntawm kev pheej hmoo ntawm macular degeneration. Piv txwv li cov cim npe ntawm LED tsob nroj lub teeb pom tau 1200 μm, uas yog 20% ntau tshaj li ntawm IEE tus qauv txwv ntawm 1000 μ W / cm ².
UV residue: qee cov khoom siv pheej yig yuav xau me me ntawm ultraviolet lub teeb (UV- ib qho 380nm) vim yog cov teeb meem uas lawv tau ntim. Kev tshawb nrhiav pom tias yuav raug rau 0.5 mw / cm² U6}}} A rau 8 teev ntau dua 3 xyoos tuaj yeem tsim tsa qhov tshwm sim ntawm cataracts.
2, hom kev pheej hmoo: siv sijhawm, lub sijhawm, thiab tsis sib xws ntawm tib neeg
1. Tus nqi ntawm lub teeb thiab ntev npaum li cas nws raug
Effects in the short term: Being directly in strong light can generate temporary glare, which can make your eyesight blurry or give you headaches. For instance, an operator at a plant manufacturer had eye tiredness symptoms after changing LED lights for two hours straight without wearing goggles. The tear film rupture time had dropped to 5 seconds (normal value>10 vib nas this) thaum nws tau kuaj xyuas.
Ntev - lub sij hawm tsub zuj zuj: prolonged raug rau cov xwm txheej nrog cov ppfd (Photosynthetic photon flux tsis zoo. Kev tshawb nrhiav kev tshawb nrhiav pom tau tias raug rau 800 μmol / ntxhais ib hnub tau coj mus ntxiv rau 15% txo qis hauv lub khob hlum dua tom qab 3 xyoos.
2. Qhov tsis sib xws ntawm kev sib xyaw ua ke
Tsis txaus liab thiab xiav lub teeb: qee hom teeb liab xiav lub teeb sib npaug rau 8: 1 los pab cov nroj tsuag kom nrawm dua vim yog qhov kev sib piv siab dua. Hauv kev sib piv kev sim, cov neeg koom nrog ua haujlwm nrog lub ntsej muag liab uas muaj 40: 1 rau 2% nce rau hauv qhov ncauj tsis pub dhau.
Qhov txawv ntawm lub zog: Tsav tsheb uas tsis zoo yuav ua rau lub teeb ci rau cov flicker (zaus<100Hz), which might give you headaches and make your eyes strain. High-frequency testing revealed that the flicker depth of a specific batch of products reached 35%, surpassing the IEEE suggested value of less than 5% by a factor of 7.
3. Qhov sib txawv ntawm cov tib neeg rhiab
Muaj hnub nyoog: Cov neeg tshaj 40 xyoo muaj lo ntsiab muag uas muaj ntau dua los ua daj, cia lub teeb xiav dua (30% tsawg dua), thiab muaj kev sib daj sib luag. Cov kev tshawb fawb kuaj mob qhia tau tias qhov kawg ntawm qhov muag nkees hauv no Cohort yog 22% ntau dua qhov uas tau pom hauv cov neeg nyob sab hauv.
Kev ua kom caj dej caj dab: qee cov neeg muaj cov retinitis genes (piv txwv, kev ua kom lub teeb poob qis ntawm cov kev puas tsuaj rau lub teeb ci ntawm kev sib tw qib txhua hnub.
3, npaj rau kev tiv thaiv: Cov Qauv rau Kev Ua Haujlwm Zoo thiab Siv
1. Zoo tsim cov khoom lag luam
Spectral optimization: Siv "tag nrho cov spectrum + controllable liab thiab xiav lub teeb" Tsim kom txaus siab cov nroj tsuag thaum txiav ntawm lub teeb xiav. Piv txwv li, lub tuam txhab tau pib "cog lub teeb kho mob" uas txiav lub teeb xiav txij 30% rau 18% thiab ntxiv 590nm daj teeb kom pab nrog qhov muag quav.
Anti {- Glare Qauv: Txo cov khoom sib txawv ntawm lub teeb pom kev mus rau hauv lub teeb pom kev zoo (egr) los ntawm 28 mus rau 16, uas yog tus qauv rau ib puag ncig ua haujlwm.
Ntse Simming System: Nws muaj lub - hauv lub teeb sensor uas tau hloov cov zis raws li qhov teeb pom kev hauv chav tsev kom tsis txhob overlexposure. Cov kev ntsuam xyuas tau pom tias lub kaw lus yuav ua rau lub teeb ci nyob rau hauv kev ua haujlwm ntawm hloov ntau dhau, rau kev hloov pauv ntau dhau lawm, rau kev hloov pauv ntau dhau.
2. Teeb tsa cov cai rau kev siv
Kev tswj kev deb: Lub teeb yuav tsum tau nruab tsawg kawg yog 1.5 meters saum av thiab nyob li 0.8 rau 1.2 meters deb ntawm kev ua haujlwm. Kev ntsuas tau pom tau hais tias qhov kev siv ntawm lub teeb ci xiav tuaj yeem coj mus rau hauv qib muaj kev nyab xeeb (<400 μ W/cm ²) at this distance.
Lub Sij Hawm Tswj: Siv cov "20-20-20", uas hais kom saib 20 ko taw (6 metres) tam sim no rau 20 feeb ntawm kev ua haujlwm. Cov kev tshawb fawb uas khaws txhua yam uas ua haujlwm uas ua raws txoj cai no yog 60% tsawg dua yuav tau txais kev qaug zog qhov muag.
Rau kev nyab xeeb ntawm tus kheej, nws yog qhov zoo tshaj plaws yuav siv goggles uas tau raws EN166 cov qauv thiab pub tsawg dua 15% ntawm lub teeb xiav los ntawm. Kev ntsuam xyuas hauv chav kuaj tau qhia tawm cov hnab looj tes no tuaj yeem tsa lub retina cov thermal kev puas tsuaj pib los ntawm peb zaug.
3. Tsa cov qauv hauv kev lag luam
Daim ntawv pov thawj rau photobiological kev nyab xeeb: txhawb kev tsim cov txheej txheem kev nyab xeeb rau cov teeb meem kev nyab xeeb coj thiab tsim nyog los qhia cov xim xiav teeb meem kev phom sij (RG0-RG3). Tam sim no, European Union hais tias txhua cov nroj tsuag teeb pom kev yuav tsum xeem cov ntawv pov thawj ua ntej lawv tuaj yeem muag tau.
PPFD txwv tus qauv: Raws li cov lus qhia raws li Asabe, PPFD hauv cov chaw ua haujlwm sab hauv tsev yuav tsum tsis txhob siab dua 1000 mol / m. Yog tias kis tau luv heev (tsawg dua 2 teev), nws tuaj yeem raug tsa rau 1500 μ mol / m a ·.
