Yuav ua li cas ua lub luag haujlwm ntawm lub chaw ntau pob teeb pom kev zoo tsim ntau dua, peb yuav tsum nkag siab txog cov qauv siv tshwj xeeb thiab cov cai ntawm kev tsim teeb pom kev hauv chaw ntau pob.Xws li lub teeb pom kev zoo, xim kub, xim rendering, glare tswj, thiab lwm yam, yuav tsum tau ua tib zoo xav thiab siv.
Illumination xav tau
Ua ib qho piv txwv ntawm kev ncaws pob, raws li 83rd daim ntawv ntawm International Federation of Sports, pom zoo illuminance rau cov chaw ntau pob thiab cov kev cai nyob rau hauv "Lighting Design Standards for Civil Buildings" GBJ133-90, peb theem illuminance rau football stadiums yuav tsum tau raws li cov cai hauv qab no:
1. Kev siv lub teeb pom kev hauv football ua piv txwv, raws li Tshooj 2.2.9-1 ntawm "Tsev Teeb Pom Kev Zoo rau Cov Tsev Hauv Tsev" GBJ133-90: tus qauv tus nqi ntawm illuminance rau kev ua si football: thaum qhov kev ncua deb yog 120m, lub illuminance yuav tsum ncav cuag 150 ~ 200 ~ 300lx;thaum pom qhov deb yog 160m, qhov illuminance yuav tsum ncav cuag 200 ~ 300 ~ 500lx;Thaum pom qhov deb yog 200m, tus nqi illuminance yuav tsum yog 300 ~ 500 ~ 750lx.Qhov kev pom deb yog hais txog qhov kev ncua deb ntawm kab kawg ntawm lub tsev kawm ntawv mus rau sab nraud ntawm qhov chaw.
2. Rau qhov kev tshaj tawm hauv xov xwm ntawm kev ua kis las, kev teeb tsa ntsug ntawm kev tshaj tawm hauv TV yuav tsum tau txiav txim siab.Raws li tsab xov xwm 2.2.9-2 ntawm "Tsev teeb pom kev zoo tsim qauv rau pej xeem vaj tse" GBJ133-90, ntsug illuminance yuav tsum tau rau TV tshaj tawm: qhov siab tshaj plaws shooting nrug yog muab faib ua peb pawg:
a.Rau cov xwm txheej ncaws pob, thaum qhov siab tshaj plaws ntawm kev tua yog 25m, qhov nruab nrab ntsug illumination yuav tsum ncav cuag 750lx;
b.Thaum qhov siab tshaj plaws tua yog 75m, qhov nruab nrab ntsug illuminance yuav tsum ncav cuag 1000lx;
c.Thaum qhov siab tshaj plaws tua yog 150m, qhov nruab nrab ntsug illuminance yuav tsum tau mus txog qib 1500lx.
Ntawm lawv, txij li ntau lub chaw ntau pob sib koom ib qho chaw rau kev ncaws pob thiab kev taug qab thiab kev ua si, cov kev xav tau ntxiv yog xav tau rau kev taug qab thiab thaj chaw cov xwm txheej: thaum qhov siab tshaj plaws tua yog 25m, qhov nruab nrab ntsug illuminance yuav tsum ncav cuag 500lx;thaum qhov siab tshaj plaws tua yog 75m, qhov nruab nrab ntsug illumination Lub illuminance yuav tsum ncav cuag 750lx;Thaum qhov siab tshaj plaws tua yog 150m, qhov nruab nrab ntsug illuminance tus nqi yuav tsum ncav cuag 1000lx.
Cov lus ceeb toom: Cov kev xav tau ntawm lub teeb pom kev ntsug tau hais los saum toj no yog siv rau qib kev ua kis las thiab tus nqi ntawm qhov kev pom zoo tshaj plaws ntawm qhov kev sib raug zoo ntawm 1.0m ntsug dav hlau, thiab tus nqi nruab nrab ntawm txhua qhov teeb pom kev zoo yog siv tau.ntawm lwm qhov kev tua.
3. Cov illuminance saum toj no yog hais txog qhov kawg nruab nrab illuminance ntawm lub chaw ntau pob.Thaum tsim teeb pom kev zoo, peb yuav tsum ntxiv cov coefficient txij nkawm, feem ntau yog tus nqi coefficient ntawm 0.7 thiab 0.8.
4. Lub uniformity ntawm kab rov tav illuminance: lub uniformity ntawm illuminance yog feem ntau qhia los ntawm qhov ratio ntawm qhov tsawg kawg nkaus illuminance mus rau lub siab tshaj plaws illuminance, thiab kuj yuav qhia tau los ntawm qhov ratio ntawm qhov tsawg kawg nkaus illuminance rau qhov nruab nrab illuminance.Qhov piv ntawm qhov tsawg kawg nkaus illuminance mus rau qhov siab tshaj plaws illuminance yuav tsum ntau dua 0.5.Tsis tas li ntawd, peb kuj yuav tsum tau them sai sai rau qhov ntsug illuminance uniformity ntawm lub venue: qhov ratio ntawm qhov tsawg kawg nkaus illuminance mus rau lub siab tshaj plaws illuminance yuav tsum ntau tshaj 0.4 kom tau raws li qhov yuav tsum tau ntawm lub TV lub koob yees duab.
Teeb pom kev zoo
1. Glare tswj
Vim tias qhov chaw ntau pob yog qhov loj, muaj ntau pawg neeg koom nrog, suav nrog cov neeg ncaws pob thiab cov neeg saib xyuas, nrog rau cov neeg saib, kev ua haujlwm hauv teb, thiab lwm yam. Yog li ntawd, thaum tsim teeb pom kev hauv chaw ntau pob, peb yuav tsum xyuam xim rau kev tswj cov glare hauv txhua qhov chaw.Nyob rau hauv txoj kev no, lub teeb pom kev zoo tuaj yeem ua tiav, cov neeg ncaws pob tuaj yeem ua tau zoo dua lawv cov kev sib tw, thiab tib lub sijhawm, cov neeg saib tuaj yeem pom cov ntsiab lus ntawm qhov kev ua si.
Raws li CIE NO.83 tshaj tawm "Kev Ua Si Field Lighting rau Xim TV Systems", qhov siab tshaj plaws glare Performance index GRmax nyob rau hauv lub tshav pob yuav tsum tsawg tshaj li 50. Qhov qis dua qhov kev ntsuam xyuas glare GR, qhov zoo dua qhov kev tswj lub teeb pom kev zoo, nrog rau qhov ci ntsa iab ntawm 50. Qhov ntsuas glare GR tuaj yeem suav nrog cov qauv hauv qab no:
GR = 27 + 24Lg, Lvl / Lve 0.9 1 Hauv cov qauv, Lvl yog qhov ci ntsa iab ntawm lub teeb kab hlau rhuav tsim los ntawm lub teeb, thiab Lve yog qhov ci ntsa iab ntawm lub teeb kab hlau rhuav tsim los ntawm ib puag ncig.Ob leeg yuav tsum tau kho nyias.Thaum peb xam qhov illuminance ntawm lub venue, peb yuav tsum nco ntsoov coj lub glare qhov tseem ceeb nyob rau hauv sib txawv cov lus qhia rau hauv tus account.Tsuas yog thaum tus nqi ntsuas GR <50, tag nrho cov tswv yim tseem tuaj yeem khiav.
Tau kawg, muaj ntau txoj hauv kev los txwv qhov ci ntsa iab, xws li xaiv hom teeb tsim nyog, kho qhov siab ntawm lub teeb, lub kaum sab xis, thiab teeb tsa lub teeb, thiab koj tuaj yeem "txo" glare los ntawm brightening keeb kwm ntawm lub arena.
2. Lub teeb qhov chaw xim kub thiab xim rendering txheem
Txhawm rau kom ua tiav qhov zoo dua saib thiab TV tshaj tawm cov teebmeem, qhov zoo ntawm lub chaw ua si teeb pom kev zoo tsis yog tsuas yog hais txog lub teeb pom kev zoo, tab sis kuj yog xim kub thiab xim rendering.Thaum lub teeb pom kev mus txog tus qauv, nws tsuas tuaj yeem tso cai rau peb "pom meej", thiab thaum xim kub thiab xim rendering ua tau raws li tus qauv, nws tuaj yeem ua rau peb "pom zoo".
Raws li cov kev cai ntawm Tshooj 3.3.2 ntawm kuv lub teb chaws "Tsev teeb pom kev zoo tsim qauv rau pej xeem vaj tse" GBJ133-90: Rau cov teeb pom kev zoo siv rau cov xim TV tshaj tawm, cov xim rendering Performance index Ra yuav tsum tsis pub tsawg tshaj 65. Tsis tas li ntawd, raws li mus rau CIE NO.83 kev tshaj tawm thiab cov kev cai ntawm FIFA, lub teeb ci xim kub Tc yog ntau dua 5000K, thiab cov xim rendering Performance index yog ntau dua los yog sib npaug rau 80. Qhov ntawd yog hais tias, nyob rau hauv lub teeb pom kev zoo tsim ntawm chaw ntau pob, lub xim kub ntawm lub teeb ci yuav tsum siab tshaj 5000K, thiab xim kub yuav tsum yog tsawg kawg yog Ra> 65.
3. Lub directionality ntawm lub teeb
Raws li tau hais ua ntej, kev tswj ntawm glare muaj ntau yam ua nrog rau kev coj ntawm lub teeb pom kev zoo.Tab sis nyob rau tib lub sijhawm, lub kaum sab xis ntawm lub teeb tuaj yeem hloov kho lub teeb pom kev zoo.Yog li ntawd, thaum tsim lub chaw ua si teeb pom kev zoo, nws yog ib qho tsim nyog los tswj lub teeb pom kev ntawm lub teeb.Tsis tas li ntawd, qhov piv ntawm lub koob yees duab tseem ceeb thiab lub teeb los ntawm sab nraud yuav tsum tau tswj nyob rau hauv ib qho chaw, thiab thaj tsam ntawm lub teeb pom kev zoo tseem yog qhov chaw ntawm lub tsev hais plaub.
Cov hluav taws xob siv rau kev teeb pom kev hauv chaw ntau pob yog kev lag luam hluav taws xob, thiab kev siv hluav taws xob ntawm tag nrho cov chaw ntau pob yog qhov loj heev.Daim nqi hluav taws xob rau ib hnub tej zaum yuav raug nqi ntau txhiab yuan.Yog li ntawd, cov teeb meem kev txuag hluav taws xob yuav tsum tau xav txog hauv kev tsim teeb pom kev zoo ntawm cov chaw ntau pob.
Rau kev txuag hluav taws xob, lub tuam txhab tsim teeb pom kev zoo tuaj yeem ua tau yog los tsim cov phiaj xwm teeb pom kev zoo, xaiv cov luminaires kom zoo, txo cov kab poob, thiab tsim kom muaj lub teeb pom kev zoo.
Thaum xaiv cov teeb pom kev zoo rau cov tsev kawm qib siab thiab tsev kawm qib siab, peb yuav tsum teeb tsa tsim nyog, ntau hom kev hloov pauv thiab cov txheej txheem tswj hwm kom hloov pauv hloov pauv rau cov kis las sib txawv.
Ntxiv mus, cov yam ntxwv no yuav tsum tau txiav txim siab tag nrho thaum pib ntawm kev tsim, txwv tsis pub nws yuav nyuaj rau kev hloov kho tom qab.
