Ingabe wonke umucu okhanyayo une-UGR?

Imethrikhi ebizwa ngokuthi i-UGR, noma Isilinganiselwa Esikhanyayo Esihlanganisiwe, isetshenziselwa ukuhlola ukuthi ukukhanya okuxhophayo okungakhululekile okuvela emthonjeni wokukhanya akulungile kangakanani. Njengoba i-UGR ivamise ukuxhunyaniswa nezindawo zokukhanyisa ezisemthethweni ezisetshenziswa kuzilungiselelo zezentengiso nezomsebenzi lapho ukulawulwa kokuxhopha kubalulekile, akuzona zonke izibani ezinaleli banga.

Imichilo yokukhanya ayikwazanga ukudlula esitifiketini esifanayo noma ezinqubweni zokuhlola njengemishini yokukhanyisa evamile, ikakhulukazi uma ihloselwe ukukhanyisa noma ukuhlobisa. Nokho, abakhiqizi bangase banikeze isilinganiso se-UGR noma imininingwane yokuphathwa kokuxhopha uma umucu wokukhanya uhloselwe ukusetshenziswa ezindaweni lapho ukuxhopha kungase kube inkinga.

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

Njengoba i-UGR iyinombolo enqunywa izilinganiso ezithile, ukuhlola Isilinganiso Esihlanganisiwe Esikhazimulayo (UGR) sesibani somugqa we-LED ngokuvamile kuhilela ukulandela inqubo emisiwe. Ukubuka konke kwezinqubo ezidingekayo ukuze kuhlolwe i-UGR kunikezwe ngezansi:

Lungiselela Imvelo:
Yenza ukuhlola endaweni elawulwayo, njengegumbi elinedizayini enqunywe kusengaphambili kanye nokwelashwa kwendawo. Eminye imithombo yokukhanya engasonta idatha akufanele ibe khona egumbini.
Amathuluzi okulinganisa:
Ukuze unqume ukuthi umthombo wokukhanya ukhanya kangakanani nezindawo ezizungezile, sebenzisa imitha yokukhanyisa. Qiniseka ukuthi imitha ilinganisiwe futhi ifanele ububanzi bokukhanya okudingeka ukale.
Misa Amaphuzu Okulinganisa:
Nquma izindawo zokulinganisa. Indawo yomuntu obukele (ngokuvamile ileveli yeso) kanye nezindawo zemithombo yokukhanya (izibani ze-strip ze-LED) kuvame ukufakwa kulokhu.
Bala Ukukhanya:
Ngokombono womuntu obukele, kala ukukhanya komugqa we-LED ngama-engeli ahlukene. Lokhu kuhlanganisa ukuthatha izilinganiso zokukhanya kuma-engeli abonisa ukuxhopha okungenzeka kanye nokusuka emthonjeni wokukhanya.

Bala i-UGR:
Sebenzisa ifomula ye-UGR, ecabangela amanani okukhanya akalwayo, ama-engeli emithombo yokukhanya ahlobene nesibukeli, kanye nokukhanya kwangemuva. Ifomula imi kanje:
[
UGR = 8 \cdot \log_{10} \kwesokunxele( \frac{0.25 \cdot \sum_{i=1}^{n} L_i \cdot \Omega_i}{L_b} \kwesokudla)
]

Kuphi:

( L_i ) = ukukhanya komthombo wokukhanya (kumakhandlela ngemitha yesikwele ngasinye)
( \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 lithathwa njengelamukelekayo, nokho amanani angaphezu kuka-19 angasikisela ukubenyezela okunzima.
Amarekhodi:
Ukuze uthole ireferensi yesikhathi esizayo noma izidingo zokuhambisana, rekhoda zonke izilinganiso, izibalo, nezimo zokuhlola.
Ukukhuluma nochwepheshe bokukhanyisa noma inkampani egxile ekwakhiweni kokukhanyisa nasekukaleni kungase kube usizo uma ungayazi inqubo yokuhlola noma ungenawo amathuluzi adingekayo.

Sinomugqa omusha ongavimbela ukuxhopha, sicelaXhumana nathiuma ufuna ukwazi okwengeziwe mayelanai-anti-glare neon strip.
