Yuav ua li cas kom tsis txhob muaj teeb meem stroboscopic hauv LED teeb?
Nrog rau kev txuag hluav taws xob ntawm LED teeb pom kev zoo thiab cov kev xav tau ntau ntxiv rau lub teeb pom kev zoo thiab teeb pom kev zoo, Codeliang ib zaug ntxiv tsom mus rau stroboscopic thiab yuav ua li cas kom tsis txhob nws.
Flicker yog qhov hloov pauv ntawm qhov siv zog lossis qhov ci ntawm lub teeb nyob rau ib lub sijhawm. Flicker tshwm sim hauv ntau daim ntawv thov teeb pom kev zoo, suav nrog qeeb - kev ua yeeb yaj kiab hauv TV (tshwj xeeb tshaj yog cov kis las kis las), qhov teeb pom kev zoo, ntau qhov chaw ntawm lub teeb pom kev zoo, thiab chaw ua haujlwm uas siv lub tshuab ceev ceev - tig. Flicker tuaj yeem cuam tshuam rau tib neeg kev noj qab haus huv, thiab qhov cuam tshuam ntawm qhov cuam tshuam yog nyob ntawm qhov zaus ntawm flicker thiab tus neeg qhov rhiab heev rau flicker. Txawm hais tias siab - zaus stroboscopic flicker tsis muaj kev cuam tshuam loj rau tib neeg lub cev, qis - zaus stroboscopic flicker qis dua 120 Hz tuaj yeem cuam tshuam rau tib neeg kev noj qab haus huv.
1. Yog li cas LED strobe generated?
Muaj ntau qhov laj thawj rau flickering. Rau kev tswj iav manufacturers, ripple tam sim no yog ib qho ntawm cov laj thawj, thiab nws yog qhov ua txhaum loj ntawm strobe. Ripple tam sim no yog AC tivthaiv uas tseem nyob tom qab kho thiab lim. Lub ripple tam sim no yog superimposed ntawm DC, nrog ntau zaus thiab nkhaus. Qhov AC tivthaiv no ua rau lub zog ntawm LED module hloov pauv, uas hloov pauv qhov ci. Tus nqi thiab zaus ntawm superimposed AC yog qhov txiav txim siab rau flicker tiam.
Cov khoom siv thev naus laus zis thiab lub teeb tsim siv los ntawm LED lub teeb ci kuj tseem ceeb rau stroboscopic flicker. Piv txwv li, yog tias phosphor siv los ua cov khoom siv hloov pauv rau lub teeb ci LED, cov txheej txheem ntawm cov khoom siv muaj cov nyhuv capacitive uas tshem tawm ib feem me me ntawm AC superimposed.
2. Yuav ua li cas kom tsis txhob muaj teeb meem stroboscopic hauv LED teeb?
Txawm hais tias LED nws tus kheej tsis muaj kev pheej hmoo ntawm stroboscopic, LED dimming, tshwj xeeb tshaj yog los ntawm pulse dav dimming, yuav ua rau lub stroboscopic hnyav dua, thiab txawm ua rau stroboscopic tshwm sim thawj qhov chaw. Txhawm rau kom tsis txhob stroboscopic, nws muaj peev xwm siv lwm txoj kev dimming, xws li analog dimming. Txhawm rau tiv thaiv qhov tsis zoo ntawm analog dimming nrog qhov tsis muaj qhov dimming, hybrid dimming yog qhov kev xaiv zoo tshaj plaws.
Ripple tam sim no cov ntaub ntawv nyob rau hauv lub tsav yog thawj qhov taw qhia ntawm flicker txaus ntshai. Yog xav paub ntau ntxiv txhim khu kev qha los txiav txim siab, saib cov ntaub ntawv ntawm tag nrho cov luminaire. Feem ntau cov chaw tsim hluav taws xob luminaire muab cov ntsiab lus ntawm tus neeg tsav tsheb siv, superimposed AC lub zog, txoj kev dimming, thiab cov zaus nkhaus. Tshwj xeeb, qhov nkhaus zaus ntawm 0 thiab 120 Hz zoo tshaj plaws qhia txog kev pheej hmoo ntawm flickering. Qhov ntau zaus ntawm 10 thiab 70 Hz tsim nyog rau kev txiav txim siab tshwj xeeb, vim tias strobes hauv qhov ntau no muaj kev cuam tshuam loj tshaj plaws rau tib neeg kev noj qab haus huv. Dab tsi ntxiv, zam PWM dimming kiag li lav flicker-dawb ambient tej yam kev mob.
Shenzhen Benwei Teeb pom kev zoo Technology Co., Ltd yog cov chaw tsim khoom lag luam hauv kev tsim cov khoom siv teeb pom kev zoo, Peb cov khoom tseem ceeb T8 T5 LED Tube, LED Loj Hlob Teeb, Nqaij qaib LED Teeb, Tri- pov thawj LED Teeb, LED Dej nyab lub teeb, LED vaj huam sib luag , LED Stadium Teeb, LED High Bay, LED Classing Room Teeb, Yog tias koj xav yuav cov khoom lag luam zoo - LED teeb pom kev zoo lossis muaj ntau yam hauv - kev nkag siab tob ntawm daim ntawv thov ntawm LED teeb pom kev zoo, thov tiv tauj xa peb nug.
