Txij li thaum lub teeb pom kev zoo nkag mus rau lub sijhawm ntawm cov teeb fluorescent, cov teeb ci nrog cov teeb pom kev zoo tau ua dej nyab peb ib puag ncig lub teeb.Raws li txoj cai luminous ntawm lub teeb fluorescent, qhov teeb meem ntawm flicker tsis tau daws tau zoo.Niaj hnub no, peb tau nkag mus rau lub sijhawm ntawm LED teeb pom kev zoo, tab sis qhov teeb meem ntawm lub teeb flicker tseem muaj.
Dab tsi yog flicker
Flicker yog qhov hloov ntawm lub teeb siv los yog ci ntsa iab hauv ib lub sijhawm.Teeb pom kev zoo flicker tshwm sim nyob rau hauv ntau daim ntawv thov teeb pom kev zoo, suav nrog kev tua qeeb hauv TV, txoj kev teeb pom kev zoo, ntau yam ntawm cov teeb pom kev zoo thiab chaw ua haujlwm uas siv cov tshuab tig nrawm.Flicker yuav cuam tshuam rau tib neeg kev noj qab haus huv, thiab qib ntawm kev cuam tshuam nyob ntawm qhov zaus ntawm flicker thiab tus kheej rhiab heev rau flicker.Kev kub ceev flicker yuav tsis muaj kev cuam tshuam loj rau tib neeg lub cev, tab sis tsawg zaus flicker qis dua 120 Hz yog ib qho yooj yim rau tib neeg noj qab haus huv.

Kev puas tsuaj ntawm teeb pom kev zoo flicker
Lub teeb ci flicker yog ze ze rau migraine, mob taub hau, autism, qhov muag nkees, qhov muag tsis pom kev thiab lwm yam kab mob neurological.Cov kev tshawb fawb tau pom tias qhov tsawg zaus, thaj tsam ntawm 3-70Hz scintillation lub teeb ci tuaj yeem ua rau muaj mob vwm rau qee tus neeg rhiab;100Hz flicker zaus tau txheeb xyuas ua rau mob taub hau thiab migraine;120Hz flickering lub teeb ci tuaj yeem cuam tshuam rau tib neeg lub siab, xws li kev ntxhov siab thiab kev ntxhov siab.Kev pom kev tsis pom kev tshwm sim los ntawm cov nyhuv flicker thiab lwm yam kev ua haujlwm ntawm lub tshuab yog qhov txaus ntshai heev hauv cov chaw ua lag luam.Yog li ntawd, ntsuas thiab ntsuas qhov flicker yam ntxwv ntawm cov khoom siv teeb pom kev zoo yog ncaj qha cuam tshuam rau tib neeg kev noj qab haus huv, uas yog ib qho teeb meem ceev uas yuav tsum tau daws.
Ua rau flicker
Yog vim li cas rau flicker ntawm LED teeb muaj xws li tsis tsuas yog cov yam ntxwv ntawm lub hwj chim mov, tab sis kuj cov yam ntxwv ntawm kev ua tau zoo ntawm lub teeb qhov chaw thiab tsis tsim nyog teeb pom kev zoo tsim.Ripple tam sim no yog ib qho tseem ceeb ua rau flicker nyob rau hauv lub hwj chim mov ntawm ntau lub teeb pom kev zoo.Ripple tam sim no yog AC tivthaiv uas tseem muaj tom qab kho thiab lim.Ripple tam sim no yog superimposed ntawm DC thiab muaj ntau zaus thiab nkhaus.Qhov AC tivthaiv no ua rau lub zog ntawm LED module hloov pauv, uas nyob rau hauv lem yuav hloov lub brightness.Qhov ntau thiab zaus ntawm superimposed AC yog qhov txiav txim siab ntawm flicker.

Yuav ua li cas tshem tawm flicker
Ntxiv nrog rau kev ua haujlwm ntawm kev tshem tawm qhov tsaus ntuj thiab teeb pom kev ib puag ncig, teeb pom kev zoo yuav tsum coj mus rau hauv tus account kev noj qab haus huv ntawm cov khoom.Kev puas tsuaj rau tib neeg yog ib feem ntawm kev ua haujlwm ntawm cov teeb uas yuav tsum tsis txhob raug ignored.
Muaj kev cuam tshuam los ntawm kev hloov kho ntawm lub zog hluav taws xob hluav taws xob (50Hz hauv European tus qauv), qhov zaus ntawm ripple tam sim no nyob rau hauv ib qho loj ntawm LED tsav yog ob zaug ntawm lub hwj chim mov, uas yog hais txog 100Hz.Ntxiv mus, piv nrog cov teeb pom kev zoo ib txwm muaj, LEDs tuaj yeem hloov pauv tam sim no ua haujlwm rau hauv lub teeb.Txhawm rau kom ua tiav lub teeb pom kev zoo tsis muaj flicker ntau li ntau tau, cov neeg tsav tsheb zoo LED thiab kev sib raug zoo ntawm cov tsav tsheb, dimmer thiab LED module yog qhov tseem ceeb.Cov duab hauv qab no yog ib txoj hauv kev los ntsuas cov cuab yeej tswj los ntawm "tso tawm tam sim no ripple" lossis "superimposed AC".Feem ntau, tus nqi qhia yog 100Hz.Tus nqi qis dua, qhov kev pheej hmoo ntawm flicker qis dua.

Wellway's LED teeb thiab lghtings, txawm tias lub teeb ntub dej, lub teeb ci ntsa iab, lub teeb ci thiab cov plua plav pov thawj, suav nrog cov qauv yooj yim thiab cov qauv ntsuas kub ceev, txhua tus paub txog kev ua haujlwm yam tsis muaj flicker.Cov khoom siv hluav taws xob zoo siv los ntawm lub teeb tuaj yeem txo qhov tso zis ripple thiab paub txog qhov zoo sib xws nrog cov khoom siv teeb.
