Txhim khu kev kawm ib puag ncig nrog LED chav kawm teeb pom kev zoo
LED teeb pom kev siv thev naus laus zis tau hloov pauv qhov chaw kawm, muab cov txiaj ntsig txuas ntxiv los ntawm cov chaw ua si thiab kis las mus rau chaw ua haujlwm thiab chav kawm. Los ntawm kev txhim kho lub teeb pom kev zoo, LED cov kev daws teeb meem txhim kho qhov zoo- kev ua tau zoo thiab kev ua tau zoo ntawm cov tub ntxhais kawm thiab cov kws qhia ntawv, ua rau lub luag haujlwm tag nrho ntawm lub tsev kawm ntawv raws li niaj hnub, nyab xeeb, thiab siab - tsev kawm ntawv zoo.
Nov yog li cas LED chav kawm teeb pom kev zoo ua rau muaj kev sib txawv hauv kev kawm.
Qhov cuam tshuam ntawm chav kawm teeb pom kev zoo rau kev kawm
Kev tshawb fawb luam tawm nyob rau hauv lubPhau ntawv Journal of Environmental Psychologyqhia tias teeb pom kev zoo tuaj yeem txhawb lossis cuam tshuam kev kawm. Txoj kev tshawb no tau qhia tias nyob rau hauv 80% ntawm cov chav kawm uas muaj 100Hz fluorescent teeb, cov tub ntxhais kawm tau ntsib kev mob taub hau thiab qhov muag tsis pom kev. Cov teeb pom kev zoo li no feem ntau ua rau pom qhov muag pom thiab flicker, uas cuam tshuam cov tub ntxhais kawm thiab txo lawv lub peev xwm los mloog.
Nyob rau hauv sib piv, LED teeb pom kev zoo zoo li niaj hnub ntuj thiab tshem tawm cov teeb meem xws li flickering thiab hnyav glare. Lub teeb ntuj raug suav tias yog qhov zoo tshaj plaws rau kev kawm ib puag ncig, thiab cov kev tshawb fawb tau pom tias cov teeb pom kev zoo uas rov ua dua nws tuaj yeem txhawb kev xav thiab kev kawm ntawm cov tub ntxhais kawm.
LED teeb pom kev hauv kev xyaum: kev nyab xeeb, kev ua tau zoo, thiab kev nkag siab
LED teeb pom kev zoo tsis yog tsuas yog txhim kho kev pom zoo xwb- nws kuj tseem pab tsim kom muaj kev nyab xeeb thiab muaj txiaj ntsig zoo hauv tsev kawm ntawv. Hauv xyoo 2017, Lub Tsev Haujlwm Saib Xyuas Kev Siv Hluav Taws Xob hauv peb chav kawm hauv Texas tau nruab nrog lub tshuab hluav taws xob tunable pom tias cov kws qhia ntawv qhia txog kev txhim kho pom zoo hauv kev kawm.
Sab hauv thiab sab nraum zoov LED teeb pom kev zoo ua kom pom tseeb, teeb pom kev zoo ib hnub thiab hmo ntuj, ua rau nws zoo tagnrho tsis yog rau cov chav kawm xwb tab sis kuj yog rau kev ua ub no thiab kev ua kis las. Lub qhov dej-lit hauv tsev kawm ntawv txhim kho kev nyab xeeb thiab ua kom cov tub ntxhais kawm muaj kev nyab xeeb txawm tias lawv mus kawm cov chav kawm, koom nrog tom qab- cov kev kawm hauv tsev kawm ntawv, lossis tawm hauv lub tsev tom qab tsaus ntuj.
Tsim Teeb pom kev zoo hauv chav kawm nrog Photometric tsom xam
Txhawm rau txiav txim siab qhov teeb pom kev zoo tshaj plaws rau kev teeb tsa kev kawm, peb tsis ntev los no tau ua ib qho kev kawm photometric ntawm tus qauv 30 ft los ntawm 28 ft chav kawm. Siv IES simulation cov ntaub ntawv uas suav txog beam kaum sab xis, xim kub (Kelvin), lumen tso zis, thiab lwm yam fixture yam ntxwv, peb soj ntsuam seb lub teeb pom kev zoo layouts yuav ua tau raws li cov qauv pom zoo.
Txoj kev tshawb no tau siv ko taw- tswm ciab (FC) los ntsuas lub teeb ci ntawm qhov chaw. Lub teeb pom kev ua haujlwm zoo tshaj plaws-xws li qhov xav tau rau kev nyeem ntawv thiab sau ntawv- feem ntau xav tau 35 txog 40 FC ntawm lub rooj. Cov chav kawm hauv nqe lus nug tam sim no raug kev txom nyem los ntawm cov teeb pom kev tsis sib xws, nrog rau FC qhov tseem ceeb xws li 8 txog 100. Qhov kev tsis sib haum no feem ntau ua rau cov kws qhia ntawv kaw lub teeb tag nrho rau hnub ci, ua rau ob qho tib si tsis zoo thiab ci ntsa iab heev uas cuam tshuam kev kawm paub.
Vim li cas LED yog qhov kev xaiv zoo tshaj plaws rau chav kawm
Raws li peb qhov kev txheeb xyuas, LED teeb pom kev zoo muaj cov kev daws teeb meem uas muab cov khoom sib xws, siab - lub teeb zoo thaum txo kev siv hluav taws xob. Hauv chav kawm tau kawm, qhov kev thov LED qhov system tsis tsuas yog txhim kho lub teeb pom kev zoo tab sis kuj txo qis cov hluav taws xob sib txuas los ntawm 60%. Kev txuag hluav taws xob ntxiv tuaj yeem ua tiav thaum lub teeb ci dimmed mus rau theem tsim nyog.
Tshaj li kev siv hluav taws xob zoo, LED systems muab kev tswj lub teeb zoo dua, txo kev saib xyuas, thiab ib puag ncig kev kawm noj qab haus huv -dawb flicker thiab glare- uas pab cov tub ntxhais kawm nyob twj ywm thiab xis nyob.
Xaus
LED chav kawm teeb pom kev zoo sawv cev ntau dua li kev txhim kho hauv tshuab; nws yog kev nqis peev rau cov tub ntxhais kawm zoo- ua tau zoo thiab kev kawm tiav. Nrog rau cov txiaj ntsig xws li kev txhawb siab thiab kev nyab xeeb rau kev txuag hluav taws xob loj, LEDs pab tsev kawm ntawv tsim kom muaj kev kawm zoo dua qub -ib chav kawm ib zaug.
