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 xa hluav taws xob los ntawm cov hlau nyias nyias. Cov teeb pom kev zoo no txawv ntawm cov khoom siv hluav taws xob txuag hluav taws xob hauv qhov uas nws tsis siv mercury vapour, uas ua rau UV teeb thaum hluav taws xob 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 Fab Kis Lub Chaw Haujlwm Saib Xyuas Khoom Noj, Ib puag ncig, thiab Kev Ua Haujlwm 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 cuab yeej qhia rau koj lub hlwb tias koj yuav tsum tau tsaug zog thaum koj xav pw, 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 nce hauv qhov kev pheej hmoo ntawm cov kab mob qhov muag xws li cov hnub nyoog ntsig txog macular degeneration thiab qhov poob ntawm qhov pom kev pom tuaj yeem tshwm sim los ntawm kev cuam tshuam ntev rau LED teeb (AMD). Raws li kev ntsuam xyuas ANSES, LED teeb yuav ua rau muaj kev phom sij rau lub retina ntxiv rau ua rau mob taub hau, pom kev qaug zog, thiab muaj kev pheej hmoo ntau ntxiv.
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 tsis pom kev 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 tib 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 lav tias lub teeb pom kev zoo ntawm LED hauv ib qho 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. Tsawg kawg yog 2-3 teev ua ntej yuav mus pw, tsis txhob ntsia cov ntxaij vab tshaus ntev dhau lawm thiab nco ntsoov so tsis tu ncua.
Yuav "sov dawb" LED teeb: ANSES tsab ntawv ceeb toom kuj qhia siv "sov dawb" LED teeb ntau dua li "txias dawb" LED teeb txij li yav dhau los emit xiav lub teeb, uas txo qis kev pheej hmoo ntawm kev puas tsuaj rau koj ob lub qhov muag.
Puas yog LED teeb pom kev zoo dua li cov fluorescent?
Ntau tshaj li lub teeb xiav tsim los ntawm LED qhov muag teeb, fluorescent qhov muag teev muaj qhov nyiam tso tawm UV hluav taws xob thiab tuaj yeem ua rau koj lub qhov muag tsis zoo. Txawm hais tias LED teeb tuaj yeem muaj ntau yam xim, lawv kuj tseem tuaj yeem tsim lub teeb sov thiab tsis muaj UV rays (raws li tau hais los saum no).
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 xim sov dua li cov cua txias dua, LEDs tsis tshua muaj teeb meem rau koj ob lub qhov muag tag nrho vim lawv tsim lub teeb xiav me ntsis thiab tsis muaj UV rays.
Qhov phom sij 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. Nws tsis zoo li qhov raug LED luv luv yuav ua mob rau koj ob lub qhov muag ntev npaum li koj ua cov kauj ruam kom zoo los tiv thaiv lawv (xws li txiav rov qab rau lub sijhawm tshuaj ntsuam thiab yuav khoom "sov dawb" teeb pom kev zoo).
