Ingabe yonke imicu yokukhanya ine-UGR?

Isilinganiso esibizwa nge-UGR, noma i-Unified Glare Rating, sisetshenziselwa ukuhlola ukuthi ukukhanya okuvela emthonjeni wokukhanya akukhululeki kangakanani. Njengoba i-UGR ivame ukuhlotshaniswa nezibani ezisemthethweni ezisetshenziswa ezindaweni zezentengiselwano nezobungcweti lapho ukulawula ukukhanya kubalulekile khona, akuzona zonke izibani ezinaleli banga.

Imichilo yokukhanya ayinakudlula ezinqubweni ezifanayo zokuqinisekisa noma zokuhlola njengamadivayisi okukhanyisa ajwayelekile, ikakhulukazi uma ehloselwe ukukhanya okuzungezile noma okuhlobisa. Kodwa-ke, abakhiqizi bangase banikeze isilinganiso se-UGR noma imininingwane ngokuphathwa kokukhanya uma umchilo wokukhanya uhloselwe ukusetshenziswa ezindaweni lapho ukukhanya kungaba yinkinga khona.

Kunconywa ukuthi ubuyekeze imininingwane yomkhiqizo noma ukhulume nomkhiqizi uma ufuna umucu wokukhanya onesilinganiso esithile se-UGR.

Njengoba i-UGR iyinombolo enqunywa yizilinganiso ezithile, ukuhlola i-Unified Glare Rating (UGR) yesibani se-LED strip ngokuvamile kuhilela ukulandela inqubo ehleliwe. Ukubuka konke kwezinqubo ezidingekayo ukuhlola i-UGR kunikezwe ngezansi:

Lungiselela Indawo:
Yenza ukuhlolwa endaweni elawulwayo, njengegumbi elinomklamo ohleliwe kanye nokwelashwa kwendawo. Eminye imithombo yokukhanya engaphazamisa idatha akufanele ibe khona egumbini.
Amathuluzi Okulinganisa:
Ukuze unqume ukuthi umthombo wokukhanya kanye nezindawo ezizungezile zikhanya kangakanani, sebenzisa imitha yokukhanya. Qiniseka ukuthi imitha ilinganisiwe futhi ifanele ububanzi bokukhanya okudingeka ukubulinganise.
Misa Amaphuzu Okulinganisa:
Nquma izindawo zokulinganisa. Indawo yomqaphi (ngokuvamile izinga lamehlo) kanye nezindawo zemithombo yokukhanya (izibani ze-LED strip) zivame ukufakwa kulokhu.
Bala Ukukhanya:
Ngokombono wombukeli, kala ukukhanya kwesibani se-LED ngama-engeli ahlukene. Lokhu kuhilela ukuthatha izilinganiso zokukhanya ngama-engeli abonisa ukukhanya okungenzeka kanye nokuqondile okuvela emthonjeni wokukhanya.

Bala i-UGR:
Sebenzisa ifomula ye-UGR, ecabangela amanani okukhanya alinganisiwe, ama-engeli emithombo yokukhanya uma kuqhathaniswa nomqapheli, kanye nokukhanya kwangemuva. Ifomula imi kanje:
[
I-UGR = 8 \cdot \log_{10} \left( \frac{0.25 \cdot \sum_{i=1}^{n} L_i \cdot \Omega_i}{L_b} \right)
]

Kuphi:

(L_i) = ukukhanya komthombo wokukhanya (kumakhandlela ngemitha yesikwele)
( \Omega_i ) = i-engeli eqinile yomthombo wokukhanya (kuma-steradians)
(L_b) = ukukhanya kwangemuva (kumakhandlela ngemitha yesikwele)

Hlaziya okutholakele:
Ezimweni eziningi, inani le-UGR elingaphansi kuka-16 libhekwa njengelamukelekayo, kodwa amanani angaphezu kuka-19 angasho ukukhanya okukhulu.
Amarekhodi:
Ukuze uthole izinkomba noma izidingo zokuthobela imithetho esikhathini esizayo, bhala phansi zonke izilinganiso, izibalo, kanye nezimo zokuhlola.
Ukukhuluma nochwepheshe wokukhanyisa noma inkampani egxile ekwakhiweni nasekulinganisweni kokukhanya kungaba usizo uma ungajwayelene nenqubo yokuhlola noma ungenawo amathuluzi adingekayo.

Sine-strip entsha engavimbela ukukhanya, sicelaXhumana nathiuma ufuna ukwazi okwengeziwe nge-umugqa we-neon ophikisana nokukhanya.
