Nws yog ib qho kev puas siab puas ntsws uas ntsuas qhov kev xav ntawm lub teeb tawm los ntawm cov khoom siv teeb pom kev zoo nyob rau sab hauv tsev pom kev rau tib neeg lub qhov muag, thiab nws cov txiaj ntsig tuaj yeem suav tau los ntawm CIE kev sib koom ua ke glare tus nqi formula raws li cov lus teev tseg.
Cov qauv kev lag luam thiab pej xeem teeb pom kev zoo tsim qauv qhia tias qhov ncaj qha glare ntawm sab hauv tsev teeb pom kev zoo raug txwv raws li qhov ci ci txwv nkhaus. Txoj kev txwv no tsuas yog rau lub teeb ci ntawm ib lub teeb xwb, thiab tsis tuaj yeem sawv cev rau tag nrho cov teeb pom kev zoo uas tsim los ntawm txhua lub teeb hauv chav. Yog li ntawd, CIE muab tso rau pem hauv ntej lub laij lej formula ntawm unified glare tus nqi (UGR) nyob rau hauv lub hauv paus ntawm synthesizing lub xam cov qauv ntawm glare nyob rau hauv ntau lub teb chaws. Nws yog qhov tsim nyog rau kev teeb pom kev dav dav ntawm chav tsev yooj yim lub voos xwmfab. Lub teeb yog sib npaug ntawm qhov sib npaug ntawm qhov sib npaug, thiab cov teeb yog ob-symmetrical nrog lub teeb faib.
The UGR ntawm LED downlights muab faib raws li hauv qab no:
| Tus nqi | Kev xav |
| 25-28 | Intolerable |
| 22-25 | Tsis xis nyob |
| 19-22 | Tolerable qib ntawm glare |
| 16-19 | Ib qho kev lees paub ntawm glare, xws li cov chaw ua haujlwm thiab cov chav kawm uas xav tau lub teeb rau lub sijhawm ntev, yog qhov tsim nyog rau qib no. |
| 13-16 | Tsis xav dazzling |
| 10-13 | Tsis hnov lub glare |
| 10 | Cov khoom qib kws tshaj lij rau cov chav ua haujlwm hauv tsev kho mob |
Tau kawg, UGR tsis yog ib qho khoom muaj nqis, nws tseem cuam tshuam nrog kev siv ib puag ncig ntawm cov teeb pom kev zoo.
Piv txwv li, qhov qis dua qhov kev xav ntawm chav tsev, qhov siab dua UGR. Lub hauv paus ntsiab lus yog qhov yooj yim heev: qhov sib txawv ntau dua ntawm qhov nruab nrab ntawm lub teeb thiab lub teeb ntawm lub teeb, qhov ntau dua qhov tsis xis nyob. Qhov no yog vim li cas ib puag ncig uas tsis tshua muaj kev cuam tshuam, xws li tuav lossis KTVs, feem ntau siv cov teeb pom kev zoo thiab cov teeb pom kev zoo es tsis txhob dai lub teeb loj hauv.
Lub sijhawm no, qhov teeb meem tuaj. Raws li lub tuam txhab teeb pom kev zoo, koj tsis paub tias ib puag ncig koj cov neeg siv khoom muab lub teeb rau hauv, yog li koj yuav tsum ua li cas? Txij li thaum nws tsis tuaj yeem tswj hwm ib puag ncig, ces peb ua UGR ntawm cov khoom nws tus kheej hauv qab 19/16/13/10, yog li ntawd nws yuav tsis ua kev puas tsuaj rau lub qhov muag ntawm cov neeg siv khoom.
Li ntawd, raws li cov neeg siv khoom zoo li cas yuav xaiv cov teeb pom kev zoo? Nws kuj tseem yooj yim heev, koj tuaj yeem xaiv downlights ugr 19 nrog micro-structured anti-glare zaj duab xis prism ntawv.
Vim li cas UGR19? Vim tias UGR muaj tus yam ntxwv, uas yog, nws yooj yim los txo los ntawm 25 mus rau 19, tab sis nws yog ib qho nyuaj heev los txo los ntawm 19 mus rau 10. Piv txwv tias koj tsuas siv ob zaug ntau zog ntawm 25 mus rau 19, mus ntawm 19 mus rau 16 yuav. raug nqi 5 npaug ntau dua, thiab tus nqi yuav kim heev. Qhov no yog vim li cas kuv thiaj li pom zoo UGR19 yog qhov kev xaiv zoo tshaj plaws.
