High txhais ib qhov muag tiv thaiv yog qhov tseem ceeb dua rausab hauv tsev LED zaub
Vim lub teeb pom kev zoo ntawm lub teeb pom kev loj loj sab nraum zoov, Guangzhou tau tshaj tawm thawj "LED txwv kev txiav txim" hauv Suav teb los tswj lub teeb muaj kuab paug, uas txwv tsis pub qhib sab nraum zoov LED cov khoom siv hluav taws xob los ntawm 22:30 tsaus ntuj txog 7:30 tom ntej. hnub.Tom qab ntawd, thaum lub vijtsam LED nkag mus rau hauv chav tsev, lub teeb ua paug raug txo qis, tab sis qhov tseem ceeb ntawm kev saib xyuas tau hloov mus rau qib "kev noj qab haus huv thiab kev nplij siab".Dab tsi ntawm sab hauv LED zaub yog noj qab nyob zoo thiab xis nyob?Yuav ntsuas kev noj qab haus huv thiab kev nplij siab li casLED zaubtau dhau los ua kev txhawj xeeb.
Cov neeg siv khoom uas feem ntau siv cov duab LED yuav pom tias yog tias lawv siv cov khoom siv LED hauv cov chav sib tham hauv tsev so, lawv qhov muag yuav hlawv thaum lawv saib lawv ntev.Ntawm lub TV program kaw qhov chaw, cov ntsiab lus ntawm LED zaub screen hloov ceev heev thiab qhov ci ntsa iab hloov sai heev, uas yuav ua rau cov neeg tuaj saib tsis xis nyob.Qee qhov tsis zoo sab hauv LED zaub yuav ua rau qhov muag qhuav, dej thiab qhov muag tsis pom kev.Qhov no yog vim li cas lub vijtsam LED sab hauv tsev tsis yog tsuas yog coj peb cov duab meej meej thiab cov yeeb yaj kiab zoo nkauj, tab sis kuj coj glare uas ua rau muaj kev puas tsuaj rau lub qhov muag.
Rau kev ntsuam xyuas ntawm qhov tsis xis nyob glare, txhua lub teb chaws hauv ntiaj teb muaj lawv tus kheej txoj hauv kev.Lub glare index method CGI (CIE Glare Index) pom zoo los ntawm CIE (International Commission on Illumination) yog ib txoj kev qhia lej zoo dua nyob rau tam sim no, uas tuaj yeem ntsuas qhov ci ntsa iab thiab lub hom phiaj.Cov lus qhia yog:
Ed - direct vertical illuminance (lx) ntawm ob lub qhov muag, los ntawm lub teeb ci ntsa iab.
Ei - Indirect ntsug illuminance (lx) ntawm lub qhov muag, los ntawm keeb kwm yav dhau.
L - qhov ci ci ntawm qhov ci ci (cd / m2).
ω– Glare qhov loj me (Sr).
P-Ghth txoj hauj lwm Performance index (Position factor).
Glare index yog qhov ntsuas ntsuas los kwv yees thiab ntsuas qhov tsis xis nyob ntawm qhov chaw ua haujlwm sab hauv tsev.Raws li lub mechanism ntawm glare tsim, LED zaub screen glare yuav muab faib ua ob hom: ncaj glare, uas yog tshwm sim los ntawm lub siab brightness ntawm LED zaub screen thiab muaj zog directivity ntawm LED teeb qhov chaw;Reflective glare yog tshwm sim los ntawm qhov sib txawv siab coefficient ntawm qee cov khoom siv LED zaub thiab qhov muaj zog ntawm kev xav ntawm lwm qhov chaw teeb.
Vision screen killer 1: direct glare
Lub vijtsam LED sab hauv tsev feem ntau yog siv hauv tsev so rooj sib tham chav, chaw ntau pob, nyob TV, concerts thiab lwm yam sijhawm.Thaum tib neeg lub qhov muag saib rau lub sijhawm ntev hauv qhov luv luv, tib neeg lub qhov muag yuav raug txhawb nqa los ntawm qhov ncaj qha glare ntawm LED zaub screen.Cov menyuam kawm ntawv ntawm qhov muag yuav ntsws, thiab qhov muag yuav hnov zoo li tsis xis nyob.Kev saib mus ntev yuav ua rau lub qhov muag puas.
Txhawm rau tiv thaiv qhov tsis pom kev ncaj qha, txoj hauv kev ncaj qha yog txo qhov ci ntawm LED zaub screen.Txawm li cas los xij, thaum txo qhov ci ntawm LED zaub screen, nws tseem poob qhov txiaj ntsig zoo ntawm sab hauv LED zaub screen - grey scale.Qhov kev ua si ntawm ob qho tib si kuj yog ib qho tseem ceeb ntawm qhov pib rau "tsawg ci ci thiab grey siab" ntawm sab hauv tsev me me suab LED zaub screen.Shenzhen Lanke Electronics Co., Ltd. tau tawg los ntawm qhov kev ua haujlwm no los ntawm kev tsim txiaj ntawm nws txoj kev nkag siab zoo ntawm sab hauv LED zaub daim ntawv thov thiab cov txiaj ntsig kev lag luam tau tsim hauv 16 xyoo ntawm LED ntim.
Lanke engineers tau tsim cov khoom ntim rau LED zaub npo uas tuaj yeem txo qhov ci ntsa iab zoo heev - Blackcrystal 2121 los ntawm kev tawg ntawm cov khoom ntim LED thiab cov txheej txheem tsim.Sib txawv ntawm cov tsoos sab hauv tsev taw tes teeb pom kev zoo LED, cov siv lead ua dub 2121 txais yuav lub teeb ci ntsa iab.Piv nrog rau cov ntsiab lus teeb pom kev zoo tib yam, qhov chaw teeb pom kev zoo ntawm qhov chaw muaj cov yam ntxwv ntawm qhov tsis tshua pom kev vim nws qhov loj thiab teeb pom kev zoo, uas ua rau txo qis qhov stimulation ntawm lub teeb ci ntsa iab rau tib neeg lub qhov muag, thiab ua rau txo qis heev. glare teeb meem uas twb muaj lawm nyob rau hauv cov tsoos LED point teeb qhov chaw khoom.
Nyob rau tib lub sijhawm, qhov chaw teeb pom kev zoo kuj tseem tshem tawm tag nrho cov khoom tshwj xeeb rau lub vijtsam LED zaub (uas yuav tsim teeb pom kev ua qias tuaj thiab ua rau kev puas tsuaj rau tus neeg saib lub retina), ua rau kom cov duab du, ua rau cov duab mos, zoo nkauj thiab zoo nkauj. , thiab txhim kho qhov pom tseeb ntawm LED zaub screen duab.
Vision screen killer 2: reflected glare
Ntxiv nrog rau nws tus kheej illumination, lub glare ntawm LED zaub screen kuj tshwm sim los ntawm kev xav ntawm lub teeb los ntawm lub teeb muaj zog nyob rau hauv ib puag ncig ib puag ncig ntawm qhov chaw ntawm LED zaub screen khoom.Tshwj xeeb tshaj yog lub LED theem tom qab screen, lub reflection glare yog tshwj xeeb tshaj yog loj.Rau kev tiv thaiv thiab kev tswj ntawm xws li glare, cov ntaub ntawv reflective yog tsuas yog xav txog.Cov dub PPA thav duab uas tsis tshua muaj kev cuam tshuam yog xaiv rau cov xim dub siv lead ua 2121. Tib lub sijhawm, cov thev naus laus zis thev naus laus zis thev naus laus zis thev naus laus zis kuj tseem siv los txo cov khoom siv hluav taws xob ntawm colloidal nto thaum lub sij hawm teeb pom kev zoo ntawm lub vijtsam zaub.Piv nrog cov hlaws teeb dawb thiab cov hlaws dub zoo tib yam, cov siv lead ua dub tuaj yeem txo cov teeb pom kev zoo los ntawm 70%, txo cov teeb pom kev zoo los ntawm lub teeb pom kev zoo.
Thaum tsom mus rau qhov zoo ntawm LED cov khoom, Lanke Electronics paub ntau ntxiv txog kev nyab xeeb thiab kev noj qab haus huv ntawm LED cov khoom.Sab hauv LED zaub npo nrog lub ntsej muag emitting li yog cov khoom tiv thaiv qhov muag hauv kev lag luam LED zaub.Lanke Electronics ua rau lub teeb tso tawm los ntawm LED teeb hlaws mos, ntuj thiab tsis muaj teeb meem rau lub qhov muag los ntawm lub teeb pom kev siv tshuab thiab kev kho deg atomization thev naus laus zis, thaum txo cov tiam ntawm kev cuam tshuam glare ntawm LED zaub screen, zoo heev txhim kho qhov tshwm sim dazzling. ntawm sab hauv LED zaub screen, thiab ua tiav cov txiaj ntsig ntawm kev tiv thaiv lub qhov muag kom raug mob thiab tshem tawm tag nrho cov teeb pom kev zoo.
Nyob rau hauv lub era ntawm sab hauv tsev me me pitch zaub thiab ntse lub neej, LED zaub yuav tsum tsis tsuas yog muaj yeeb yuj thiab muaj ib tug ntev kev pab cuam lub neej, tab sis kuj coj mus rau hauv tus account kev nyab xeeb thiab kev nplij siab ntawm viewers.Tsuas yog lub vijtsam noj qab haus huv tuaj yeem nyob ze rau kev noj
