Kodi mizere yowala yonse ili ndi UGR?

Metric yotchedwa UGR, kapena Unified Glare Rating, imagwiritsidwa ntchito kuwunika momwe kunyezimira kochokera pagwero la kuwala kulili kovutirapo. Popeza UGR nthawi zambiri imalumikizidwa ndi zida zowunikira zowunikira zomwe zimagwiritsidwa ntchito pazamalonda ndi akatswiri komwe kuwongolera kwa glare ndikofunikira, si mizere yonse yowunikira yomwe ili ndi giredi iyi.

Zingwe zowala sizingadutse muzotsimikizira kapena kuyesa njira zomwezo ngati zida zowunikira wamba, makamaka ngati zidapangidwa kuti ziziwunikira mozungulira kapena zokongoletsa. Komabe, opanga atha kupereka mavoti a UGR kapena tsatanetsatane wa kasamalidwe ka glare ngati chingwe chowunikira chikuyenera kugwiritsidwa ntchito m'malo omwe kunyezimira kungakhale vuto.

Ndibwino kuti muwonenso zomwe zagulitsidwa kapena lankhulani ndi wopanga ngati mukufuna chingwe chopepuka chokhala ndi ma UGR enaake.

Popeza UGR ndi nambala yotsimikiziridwa ndi miyeso inayake, kuyesa Unified Glare Rating (UGR) ya kuwala kwa LED nthawi zambiri kumaphatikizapo kutsatira ndondomeko yokhazikitsidwa. Chidule cha njira zomwe zimafunikira kuyesa UGR zaperekedwa pansipa:

Konzani Chilengedwe:
Yesetsani kuyesa mokhazikika, monga chipinda chokhala ndi makonzedwe okonzedweratu ndi machiritso apamwamba. Zina zowunikira zomwe zimatha kusokonekera deta siziyenera kukhalapo m'chipindamo.
Zida Zoyezera:
Kuti mudziwe kuwala kowala ndi malo ozungulira, gwiritsani ntchito luminance mita. Onetsetsani kuti mita ndiyojambulira komanso yogwirizana ndi mtundu wa kuwala komwe muyenera kuyeza.
Khazikitsani Mfundo Zoyezera:
Dziwani malo oyezera. Malo a wowonera (nthawi zambiri mulingo wa diso) ndi malo omwe amawunikira (zowunikira za LED) nthawi zambiri zimaphatikizidwa mu izi.
Werengani Kuwala:
Kuchokera pakuwona kwa wowonera, yesani kuwala kwa mizere ya LED pamakona osiyanasiyana. Izi zikuphatikizapo kuyeza kuwala kwa ngodya zomwe zimanyezimira zotheka komanso molunjika kuchokera kugwero la kuwala.

Werengerani UGR:
Gwiritsani ntchito fomula ya UGR, yomwe imaganizira za kuchuluka kwa kuwala komwe kuyezedwa, makona a magwero a kuwala okhudzana ndi wowonera, ndi kuwunikira kumbuyo. Fomula yake ndi iyi:
[
UGR = 8 \cdot \log_{10} \kumanzere( \frac{0.25 \cdot \sum_{i=1}^{n} L_i \cdot \Omega_i}{L_b} \kumanja)
]

Kumene:

( L_i ) = kuwala kwa gwero la kuwala (mu makandulo pa lalikulu mita)
( \ Omega_i ) = ngodya yolimba ya gwero la kuwala (mu steradians)
( L_b ) = kuwala chakumbuyo (mu makandulo pa lalikulu mita)

Unikani zomwe mwapeza:
Nthawi zambiri, mtengo wa UGR wosakwana 16 umadziwika kuti ndi wovomerezeka, koma zopitilira 19 zitha kutanthauza kunyezimira kowopsa.
Zolemba:
Kuti mumve zambiri zamtsogolo kapena kuti mukwaniritse zofunikira, lembani miyeso yonse, mawerengedwe, ndi miyeso yonse.
Kulankhula ndi katswiri wounikira kapena kampani yomwe imayang'ana kwambiri kapangidwe ka kuunikira ndi kuyeza kwake kungakhale kothandiza ngati simukuzindikira njira yoyesera kapena mulibe zida zofunika.

Tili ndi chingwe chatsopano chomwe chitha kuletsa kuwala, chondeLumikizanani nafengati mukufuna kudziwa zambiri zaanti-glare neon strip.
