Puas yog LED teeb tiag tiag phem rau koj ob lub qhov muag?
Luag tawm! Tsis yog txhua qhov xov xwm tsis zoo ...
Txij li thaum lawv cov kev taw qhia nyob rau hauv 1962, LED teeb tau txais koob meej raws li qhov kev xaiv nyob deb dua rau cov qhov muag teev teeb. Lawv tuaj yeem teeb rau txhua chav hauv ntau lub xim thiab raug nqi ntau dua - siv tau ntxiv rau kev ua kom muaj zog ntau dua - siv tau. Nws yuav zoo li zoo dhau los ua qhov tseeb, thiab nws yog qhov tseeb tshaj plaws! Raws li kev tshawb fawb tsis ntev los no, lub teeb xiav tawm los ntawm LED teeb tuaj yeem ua rau peb lub qhov muag. Txawm li cas los xij, tsuav koj txwv koj lub sijhawm tshuaj ntsuam, qhov cuam tshuam ntawm LED teeb tsis muaj teeb meem.
Dab tsi yog LED teeb?
Tam sim no rau qhov technical part!
Txoj kev LED teeb tsim lub teeb txawv ntawm cov teeb pom kev zoo. LEDs siv lub semiconductor, uas thaum lub zog ntws los ntawm nws, tsim lub teeb, tsis zoo li cov teeb pom kev zoo, uas dhau hluav taws xob los ntawm cov hlau nyias nyias. Daim ntawv teeb pom kev zoo no txawv ntawm cov qauv siv hluav taws xob- txuag qhov muag teev nyob rau hauv uas nws tsis siv mercury vapour, uas ua rau UV teeb thaum lub zog dhau los ntawm nws. Lub phosphor txheej nyob rau hauv lub teeb ces absorbs UV hluav taws xob, uas yog dab tsi muab lub teeb ci nws ci.
Puas LED teeb puas ua rau peb lub qhov muag puas?
Lub teeb xiav emissions los ntawm LED teeb tau pom nyob rau hauv ib txoj kev tshawb fawb los ntawm Fabkis Lub Chaw Haujlwm Saib Xyuas Khoom Noj, Ib puag ncig, thiab Kev Noj Qab Haus Huv thiab Kev Nyab Xeeb (ANSES) los ua phem rau retina hauv qhov muag. Raws li lub teeb xiav ntawm koj lub tshuab hluav taws xob qhia rau koj lub hlwb tias koj yuav tsum tau nce thaum koj xav pw tsaug zog, nws tuaj yeem cuam tshuam rau koj lub cev lub cev circadian atherosclerosis.
Raws li txoj kev tshawb no, ntev raug rau LED teeb yog "phototoxic," uas thaum kawg tuaj yeem ua rau cov hlwb tsis zoo thiab tsis pom kev pom. Kev laus ntawm cov ntaub so ntswg tuaj yeem ua kom nrawm dua los ntawm kev cuam tshuam ntev rau LED teeb, uas tuaj yeem ua rau muaj kev pheej hmoo ntawm qhov muag mob xws li hnub nyoog - ntsig txog macular degeneration (AMD) thiab txo qhov pom kev pom. Raws li kev soj ntsuam ntawm ANSES, LED teeb yuav ua rau muaj kev puas tsuaj rau lub retina ntxiv rau qhov ua rau mob taub hau, pom kev qaug zog, thiab muaj kev pheej hmoo ntawm kev sib tsoo.
Puas LED teeb ua rau koj lub qhov muag nkees?
Hmoov tsis zoo, kev siv lub teeb ci LED kuj muaj qhov tsis zoo ntawm qhov ua rau qhov muag pom hauv cov neeg uas twb muaj mob xws li mob migraines thiab qaug dab peg. Qhov no yog vim lub fact tias LEDs emit ib tug extraordinarily lub teeb flicker uas mus los ntawm sai heev yuav tsum tau pom. Qhov no qhia tau hais tias feem coob ntawm cov neeg tsis muaj kev cuam tshuam, yog li tshwj tsis yog tias koj tsis tshua muaj siab thiab ua rau cov teeb meem no, nws tsis zoo li tias koj yuav mob taub hau, qaug dab peg, lossis qhov muag tsis pom lossis qaug zog.
Yuav ua li cas thiaj li LED teeb tiv thaiv peb lub qhov muag?
Muaj ob peb txoj hauv kev los xyuas kom meej tias LED teeb pom kev zoo nyob rau hauv txhua yam khoom siv uas koj siv yuav tsis ua rau koj ob lub qhov muag puas ntau dhau los ntawm kev tiv thaiv lawv los ntawm overexposed rau lub teeb xiav. Koj tuaj yeem siv ntau yam txuj ci, xws li:
Sim siv sijhawm tsawg dua nyob rau pem hauv ntej ntawm LED teeb, suav nrog cov ntawm koj lub smartphone, khoos phis tawj, lossis TV screen, yog lub tswv yim zoo. Yam tsawg kawg 2-3 teev ua ntej yuav mus pw, tsis txhob ntsia ntawm cov ntxaij vab tshaus ntev dhau lawm thiab nco ntsoov ua kom nquag plias.
Yuav "sov dawb" LED teeb: ANSES tsab ntawv ceeb toom kuj qhia txog kev siv "sov dawb" LED teeb es tsis yog "txias dawb" LED teeb vim hais tias yav dhau los emit xiav lub teeb, uas txo qhov kev pheej hmoo ntawm kev puas tsuaj rau koj ob lub qhov muag.
Puas yog LED teeb pom kev zoo dua - zoo dua li cov fluorescent?
Ntau tshaj li lub teeb xiav tsim los ntawm LED teeb qhov muag teev, fluorescent qhov muag teev muaj qhov nyiam tshaj tawm UV hluav taws xob thiab tuaj yeem ua mob rau koj lub qhov muag tshaj plaws. Raws li yav dhau los tau sau tseg, LED teeb kuj tseem tuaj yeem muab lub teeb sov so vim tias lawv tuaj yeem ua ntau yam xim thiab tsis tawm ib qho UV rays.
Lwm qhov kev xaiv yog lub teeb fluorescent compact (CFLs), uas tso tawm tsawg dua UV hluav taws xob ntau dua li ob qho tib si lub teeb thiab fluorescent teeb. Txawm hais tias CFL qhov muag teev tuaj yeem muaj mercury, uas tuaj yeem ua rau muaj kev phom sij, lawv ua li ntawd nyob rau hauv qis dua li cov teeb fluorescent. Yog tias koj xaiv lub teeb sov sov dua li cov cua txias dua, LEDs tsis tshua muaj teeb meem rau koj lub qhov muag tag nrho vim tias lawv tsim lub teeb xiav me ntsis thiab tsis muaj UV rays.
Qhov kev pheej hmoo ntawm qhov muag loj yog qhov tsis txaus ntseeg, yog li tsis txhob txhawj xeeb yog tias koj nyob ntawm lub laj kab txog kev siv cov teeb ci LED los dai koj lub tsev.
