UGR LED Panels yog dab tsi?

UGR sawv cev rau dab tsi?

Ib txoj hauv kev los piav txog qhov ci ntsa iab yog los ntawm nws lub npe, UGR. Kev piav qhia lej ntawm lub luminaire lub peev xwm glare.
 

Glare, yog dab tsi?

Thaum ob lub teeb pom kev ncaj qha rau ntawm tus neeg lub qhov muag, qhov tshwm sim hu ua glare tshwm sim. Feem ntau, txhua leej txhua tus tau nyob ntawd: sim pom txoj kev ua ntej hauv qhov tsaus ntuj vim tias lub tsheb mus txog lub teeb taws. Ib yam li ntawd, thaum teeb pom kev tsis zoo hauv qhov chaw ua haujlwm tawm ntawm cov ntxaij vab tshaus hauv computer, ua rau nws nyuaj rau pom qhov pom, qhov no kuj yuav tshwm sim.

Kev taw qhia ntawm siab -efficiency edge-lit LED vaj huam sib luag tau feem ntau ua rau muaj qhov pom kev nce qib, txawm tias nyob rau hauv rooj plaub uas lub khoos phis tawj qhia tsis pom lub teeb. Qhov no yog vim hais tias lub teeb yog coj mus rau lub luminaire lub diffusing nto es tsis txhob yog concentrated nyob rau hauv ib tug reflector los yog louvre system. Standard LED panels tsim glare vim lawv cov ci ntsa iab heev txheeb ze rau lub nraub qaum, uas yog tshwm sim los ntawm lawv 100% ncaj illuminance.

Yuav ua li cas kom muaj nuj nqis glare?

Ib qho kev sib npaug yog siv los xam qhov ntsuas UGR:

8 npaug ntawm logarithm ntawm [0.25/Lb Ʃ(L2Ω/p2)] yog UGR.

Lub luminaire tus nqi luminance yog denoted los ntawm L. Luminance ntawm lub backdrop, denoted li Lb,

Raws li kev soj ntsuam, Ω sawv cev rau lub kaum sab xis ntawm lub teeb ci.

Lub Guth Index yog denoted los ntawm p. Qhov Visual Comfort probability yuav siv qhov ci ci no rau hauv tus account.

Kev suav tag nrho cov fittings hauv qhov chaw yog qhia los ntawm Sigma kos npe (ǩ) hauv kev suav.

Tag nrho cov no taw qhia rau qhov tseeb tias qhov chaw lub cev yog qhov tsim nyog rau kev suav UGR tsim nyog. Lub chaw kuaj sim tsis yog qhov chaw ntsuas nws.
 

Yuav ua li cas glare tswj ua ntej LEDs?

Teeb pom kev zoo ntawm lub teeb ci, tsis tshua muaj kev cuam tshuam ntawm cov khoos phis tawj desktop thaum ntxov yog qhov teeb meem loj. Muaj ob txoj hauv kev los daws qhov no:

Cov neeg tsim khoom ntawm cov saib tau pib ua cov duab uas tsis muaj kev cuam tshuam lub teeb. Muaj kev qhia txog CAT2 fluorescent teeb fixtures. Lawv 65℃txiav-tawm lub kaum sab xis ua rau lawv tsis tshua pom.

Muaj qhov tsis zoo rau ob txoj hauv kev:

Qhov sib piv thiab xim brilliance ntawm matte qhia tau ploj zuj zus. Tsawg sharpness, uas tej zaum yuav mob me me los txiav txim siab nyob ntawm qhov tuab thiab txheej txheej ntawm matte nto thiab tus saib lub pixel pitch Feem ntau, cov av nkag mus tau yooj yim dua, ua rau kev tu lub luag haujlwm tseem ceeb dua. Grainy los yog hazy kev ntxhib los mos tej zaum yuav pom nyob rau hauv tej rooj plaub, tshwj xeeb tshaj yog thaum cov xim dawb los yog lwm yam xim ci.
 

Ntawm LED cov ntxaij vab tshaus, lub teeb ci tswj tau li cas?

Tom qab lub diffuser ntawm lub siab - zoo LED vaj huam sib luag yog peb yam tseem ceeb:
1.Lub teeb yog coj mus rau lub diffuser ntawm "Light Guide Plate."
2. Ib daim ntawv uas qhia txog lub teeb ntawm sab hauv lub vaj huam sib luag thiab xa rov qab mus rau Lub Teeb Qhia Phaj
Vim yog lawv cov qauv tsim, LED vaj huam sib luag muab lub kaum sab xis dav ntawm 120 degrees, uas, hauv qee qhov kev teeb tsa, yuav ua rau UGR qib siab tshaj cov lus pom zoo hauv BSEN 12464: 2002. Ib qho tshwj xeeb diffuser, zoo ib yam li louvres ntawm CAT2 luminaire, yuav txo tau LED vaj huam sib luag lub kaum sab xis thiab thiaj li daws tau qhov teeb meem no. Vim tias lub teeb tsom mus rau qhov tseeb, kev txuag hluav taws xob ntxiv yog qee zaum ua tau, uas yog ib qho ntxiv perk.
 

Cov ntaub ntawv tseem ceeb hais txogUGR19 LED vaj huam sib luag

Cov LED vaj huam sib luag, uas tseem hu ua UGR<19, are made to help get a UGR19 rating in an installation, but they don't guarantee it, since the UGR rating that is achieved depends on the exact installation.

UGR ntsuam xyuas hauv kev teeb tsa tiag tiag

Cov kev ntsuam xyuas UGR pom zoo yog qhia hauv qab no:
