1. Dab tsi yog stroboscopic
Stroboscopic yog hais txog qhov hloov pauv ntawm lub luminous flux ntawm lub teeb hluav taws xob ntawm qee zaus. Taw tes ntawm lub teeb ci nrog lub xov tooj ntawm tes feem ntau tuaj yeem pom cov kab txaij faib, uas yog tshwm sim los ntawm stroboscopic. Qee theem ntawm flicker tsis pom, thiab tsis muaj qhov tsis xis nyob ntawm lub cev; tab sis qee qhov flickers yog teeb meem tiag tiag.
Raws li thaum ntxov xyoo 1990, ntau cov kev tshawb fawb tau pom tias lub teeb ci flickering muaj feem cuam tshuam nrog cov kab mob hauv lub paj hlwb xws li migraine, mob taub hau, autism, pom kev qaug zog thiab tsis xis nyob. Nyob rau hauv cov xwm txheej hnyav, nws tuaj yeem ua rau muaj kev cuam tshuam ntawm tib neeg lub qhov muag, thiab tom qab ntawd ua rau muaj kev sib tsoo. Don't underestimate lub strobe, sib txawv frequencies thiab fluctuation depths muaj txawv los rau tib neeg!
1. Pom pom strobe
Tib neeg lub qhov muag yog ib tug complex system, thiab ib tug neeg sib txawv loj heev. Rau cov neeg feem coob, lub teeb flicker hauv qab 80 Hz tuaj yeem pom tau. Lub sijhawm no, tib neeg lub qhov muag tuaj yeem pom qhov pom kev hloov pauv thiab tsaus ntuj. Lub flicker zaus hauv qab 80 Hz kuj hu ua Nws pom flicker. Pom pom stroboscopic tsis tuaj yeem lees txais rau cov teeb pom kev zoo lossis cov duab.
♦ Tib neeg lub qhov muag' s rhiab heev rau stroboscopic hnyav muaj nuj nqi
2. Cov nyhuv Stroboscopic
Rau stroboscopic saum 80Hz, tib neeg lub qhov muag tsis yooj yim rau kev kuaj pom, tab sis nws muaj kev cuam tshuam ntau dua rau tib neeg lub qhov muag' s spatial perception. Piv txwv li, cov khoom txav yog suav tias yog cov duab tseem ceeb, uas yog, cov nyhuv stroboscopic. Vim yog cov nyhuv stroboscopic, tib neeg yuav muaj kev tsis pom kev, thiab nws yog qhov txaus ntshai heev rau kev xav txog qee yam khoom siv ceev ceev raws li kev khiav qeeb lossis txawm tias nyob twj ywm.
♦ Qhia txog cov nyhuv stroboscopic
♦ Lub illusion ntawm lub tshuab ua haujlwm los ntawm cov nyhuv stroboscopic
3. Phantom tshwm sim
Ib yam li ntawd, thaum lub flicker zaus ntawm lub teeb qhov chaw yog 80Hz-2kHz, thiab cov khoom nyob rau hauv ib puag ncig nyob twj ywm, thaum tib neeg lub qhov muag tsiv mus nyob rau hauv txoj hauj lwm los yog kev taw qhia, lub teeb nyob ruaj ruaj yuav tshwm sim lub teeb qhov chaw ntawm lub system, uas yog hu ua phantom phenomenon, xws li tsheb taillights. , Los yog saib ntawm sab nraum zoov LED zaub, thiab lwm yam.
4. Cov phom sij ntawm stroboscopic
Lub teeb ci flickering yog ze ze rau ntau yam kab mob neurological xws li migraine, mob taub hau, autism, qhov muag nkees, thiab qhov muag tsis pom kev. Cov kev tshawb fawb pom tau hais tias tsawg zaus flicker lub teeb qhov chaw ntawm 3-70 Hz yuav ua rau photosensitive epilepsy rau qee tus neeg; flicker zaus ntawm 100 Hz yog suav hais tias ua rau mob taub hau thiab migraines; Flicker lub teeb qhov chaw ntawm 120 Hz zaus tuaj yeem cuam tshuam rau tib neeg txoj kev xav, xws li kev ntxhov siab, kev ntxhov siab, thiab lwm yam. Qhov pom kev tsis pom kev tshwm sim los ntawm cov nyhuv stroboscopic thiab lwm yam kev txav chaw hauv lub sijhawm yog qhov txaus ntshai heev hauv cov chaw lag luam. Yog li ntawd, qhov tseeb ntsuas thiab ntsuas ntawm cov yam ntxwv stroboscopic ntawm cov khoom teeb pom kev zoo yog ncaj qha cuam tshuam rau tib neeg' cov teeb meem kev noj qab haus huv, uas yuav tsum tau kho sai.
2. Vim li cas LED flicker?
LED teeb pom kev zoo khoom yog tsav los ntawm AC mus rau DC tsis tu ncua voltage los yog tas li tam sim no fais fab mov. Lub teeb ci nws tus kheej tsis tsim stroboscopic. Lub xub ntiag los yog tsis muaj stroboscopic flicker nyob ntawm LED tsav fais fab mov. Vim tias cov tsav tsheb sib txawv heev, qhov kev ua tau zoo ntawm stroboscopic ntawm txhua yam khoom siv LED sib txawv. Tshwj xeeb, txhawm rau txuag cov nqi, qee cov tuam txhab siv cov tsav tsheb yooj yim, xws li AC LEDs, uas yuav ua rau muaj teeb meem ntau dua stroboscopic.
Rau cov khoom siv teeb pom kev zoo, dimming yog qhov tseem ceeb, thiab dimming tsuas yog lwm qhov ua rau strobe. Thaum cov khoom yog loaded nrog lub dimming muaj nuj nqi, lub stroboscopic flicker nyhav rau ntxiv aggravated. Tshwj xeeb tshaj yog thaum lub dimming yog tsaus, qhov sib txawv qhov tob yog qhov loj, raws li qhia hauv daim duab hauv qab no. Yog li ntawd, rau cov khoom siv teeb pom kev zoo uas muaj qhov dimming muaj nuj nqi lossis thov kom txuas nrog lub tshuab dimming, lawv qhov kev ua haujlwm stroboscopic yuav tsum tau ntsuas thaum lub dimming yog qhov ci tshaj plaws thiab qhov dimming yog qhov tsaus ntuj.
♦ Flicker waveform ntawm dimming LED teeb
Ntau tshaj kaum xyoo dhau los, cov neeg feem coob yuav tsis xav tias qhov teeb pom kev zoo thiab kev noj qab haus huv yuav muaj kev sib raug zoo. Tom qab ntau tshaj kaum xyoo ntawm txoj kev loj hlob, LED teeb pom kev lag luam kev lag luam tau ploj mus los ntawm kev nrhiav lub teeb pom kev zoo, txuag hluav taws xob thiab nqi rau lub teeb pom kev zoo, lub teeb pom kev zoo, kev nyab xeeb photobiological thiab ib puag ncig lub teeb. Tshwj xeeb tshaj yog nyob rau hauv xyoo tas los no, lub teeb xiav teeb pom kev zoo tshwm sim los ntawm LEDs, tib neeg txoj kev tsis sib haum xeeb, thiab tib neeg lub qhov muag qhov muag tau maj mam tshwm sim, ua rau kev lag luam paub txog qhov kev xav tau ceev ceev rau kev noj qab haus huv teeb pom kev zoo.
Kev noj qab haus huv teeb pom kev zoo yuav dhau los ua qhov hluav taws xob tom ntej hauv LED teeb pom kev lag luam.
