Tsis muaj ntaub ntawv yuav ua rau muaj teeb meem, thiab hauv John cov ntaub ntawv, nws ua rau mob migraines.
John sai hloov cov teeb ci kim kim hauv nws lub tsev nrog cov LEDs pheej yig uas koj tuaj yeem nrhiav tau txhua qhov chaw tom qab paub tias LED qhov muag teev tsis flicker. Rau nws txoj kev ntxhov siab, nws pom tias cov teeb ci LED tuaj yeem flicker, uas tuaj yeem muaj ntau yam tsis zoo, xws li mob migraines.
John pom peb lub vev xaib thaum muaj mob migraines thiab cov teeb meem flickering thiab nrhiav kev pab. Tsuas yog yuav LEDs uas tsis flicker yog peb cov kev taw qhia.
Qhov teeb meem yog qhov no. LEDs tsis tsim sib npaug. LEDs tuaj nyob rau hauv ob hom: cov uas flash thiab cov uas tsis. Feem ntau ntawm LED teeb ntawm peb lub vev xaib tsis flash.
Lub teeb LED twg yuav flicker thiab qhov twg yuav tsis? Kuv tuaj yeem paub ua ntej li cas? Koj tuaj yeem nug.
Txhawm rau pom peb lub teeb ci LED uas tsis muaj flicker, mus saib ntawm no.
Tab sis kuv tsis pom ib qho flashing hauv kuv lub teeb LED. Yog li vim li cas ho sim, koj nug?
LEDs tuaj yeem flicker kom meej meej (raws li hauv John's rooj plaub) los yog zais cov nyhuv stroboscopic, uas tuaj yeem hnav koj tawm, ua rau koj chim siab, thiab qee zaus, ua rau koj mob migraines.
Dab tsi yog stroboscopic?
Thaum peb cog lus tias yuav ua kom ncaj ncees raws li qhov ua tau, nws yog qhov tseem ceeb uas peb nkag siab tias lo lus "stroboscopic effect" hais txog dab tsi.
Qhov cuam tshuam stroboscopic tau piav qhia los ntawm PHYSORG raws li hauv qab no:
Thaum ib qho khoom txav tau teeb pom kev los ntawm lub teeb hloov pauv, cov nyhuv no tshwm sim raws li cov duab tseem ceeb. Cov nyhuv no feem ntau siv hauv discotheques hauv nws qhov kev mob siab tshaj plaws.
Cov teebmeem stroboscopic los ntawm LED teeb tuaj yeem yog qhov tsis xav tau.
Peb yam tseem ceeb yuav tsum nco ntsoov thaum xav txog cov nyhuv stroboscopic:
Cia peb xav txog qhov yooj yim uas tsuas muaj ob hom stroboscopic teeb: ib qho uas koj tuaj yeem pom thiab ib qho uas koj tsis tuaj yeem.
Txawm li cas los xij, txawm tias pom lub teeb stroboscopic yuav luag nyuaj rau kev paub qhov txawv yog tias koj tsis paub yuav nrhiav dab tsi.
Qhov ntau yam tsis pom zoo yog ib yam uas koj tsis tas yuav txhawj xeeb vim nws tsis cuam tshuam nrog cov kev mob tshwm sim (Peb xav tias, nws yog ib qho xwm txheej yog tias koj tsis pom nws, koj tsis tas yuav txhawj txog nws). Thaum kawg, cov nyhuv stroboscopic perceptible yog teeb meem rau koj vim hais tias nws tuaj yeem ua rau cov kev mob tshwm sim tau piav qhia saum toj no.
Peb xav hais ntxiv tias koj yuav tsum nco ntsoov xyuas seb lub teeb LED puas muaj qhov "flicker-free" kos npe ua ntej yuav khoom vim tias txawm tias koj lub LED tsis tshwm sim flickering, koj yuav tsum tsis txhob xav tias nws tsis yog vim nws yuav. yuav tsim cov nyhuv stroboscopic uas koj tsis pom.
Txhawm rau nkag mus rau hauv paus ntawm "koj lub teeb LED yuav flickering tab sis koj yuav tsis pom nws" conundrum, muaj kev sim ceev uas koj tuaj yeem ua tau.
Yog tias koj ceev nrooj viav vias tus cwj mem nce thiab nqis rau pem hauv ntej ntawm lub teeb LED thiab tom qab ntawd sai sai ua tib yam thaum sawv ntsug ntawm lub qhov rais, koj yuav tsum pom qhov hloov pauv. Yog tsis yog, tsis muaj kev txhawj xeeb.
Koj lub teeb LED yog tsim cov nyhuv stroboscopic perceptible, uas raws li peb tau hais ua ntej tuaj yeem muaj qhov tsis zoo, yog li hloov cov qij no sai li sai tau nrog cov qij tsis flickering yog tias koj pom qhov muag tsis pom kev tas li thaum koj viav vias tus cwj mem sai thiab nqis. nyob rau hauv pem hauv ntej ntawm lub qhov rais tab sis txhua yam uas pom nyob rau hauv pem hauv ntej ntawm koj lub teeb yog tseem dluab.
Tau kawg, nws yuav yooj yim dua yog tias koj nyuam qhuav yuav lub teeb tsis flickering LED thawj qhov chaw; txoj kev ntawd, koj yuav tsis tau xav txog ib yam.
