Ungayehlisa kanjani i-UGR?
I-glare yokukhubazeka ingukukhanya okunciphisa ukusebenza kahle kokubuka nokubonakala, futhi kuvame ukuhambisana nokungakhululeki. Ngokuyinhloko kubangelwa ukukhanya okunhlanhlathayo okuvela emithonjeni yokukhanya yokukhanya okuphezulu okungena iso emkhakheni wokubuka, kusakazeka ngaphakathi kwamehlo futhi kunciphise ukucaca kwesithombe nokungafani kwezinto eziku-retina. I-glare yokukhubazeka ikalwa ngesilinganiso sokubonakala komsebenzi ngaphansi kwendawo yokukhanyisa enikeziwe ekubonakaleni kwayo ngaphansi kwezimo zokukhanyisa okuyireferensi, okubizwa ngokuthi i-disability glare factor. (DGF)
I-Discomfort glare, eyaziwa nangokuthi "i-psychological glare", isho ukucwayiza okubangela ukungaphatheki kahle kokubukwayo kodwa okungabangeli ukuncipha kokubonakala.
Lezi zinhlobo ezimbili zokuxhopha zibizwa nge-UGR (Unified Glare Rating), noma inani elikhanyayo elilinganayo, okungenye yokuqukethwe okuyinhloko kokuhlolwa kwekhwalithi yokukhanyisa ekwakhiweni kokukhanyisa. Lezi zinhlobo ezimbili zokucwebezela zingavela ngesikhathi esisodwa, noma zingabonakala zingabodwa. I-UGR efanayo akuyona nje inkinga ebonakalayo, kodwa futhi inkinga yokuklama kanye nesicelo. Ngakho-ke indlela yokunciphisa i-UGR ekusebenzeni kuyinkinga ebalulekile.
Ngokuvamile, isibani sakhiwe izindlu, abashayeli, imithombo ukukhanya, lens noma ingilazi. Futhi ekuqaleni komklamo wesibani, kunezindlela eziningi zokulawula amanani e-UGR, njengokulawula ukukhanya kwemithombo yokukhanya, ukuhlinzeka ngomklamo ophikisana nokuxhopha kwilensi, noma ukwengeza isihlangu esikhethekile ukuvimbela ukuchitheka.
Embonini, iyavuma ukuthi ayikho i-UGR uma isibani esijwayelekile sihlangabezana nemibandela elandelayo.
1) I-VCP (amathuba okunethezeka okubonwayo) ingaphezu kwama-70.
2) Uma ubheka uqonde noma uvundlile egumbini, isilinganiso sobukhulu besibani sokukhanya (okukhanya kakhulu ngu-6.5 cm²) kuya ekukhanyeni okumaphakathi ngu-5:1 ku-engeli engu-45deg, 55deg, 65deg, 75deg no-85deg.
3) Isidingo sokugwema ukuxhopha okungajabulisi kungakhathaliseki ukuthi ubuka mpo noma ubheke eceleni kanjani lapho isibani nomugqa oqondile etafuleni kuma-engeli ahlukahlukene okukhanya okuphezulu kungakwazi ukweqa ishadi elingezansi.
Ngakho-ke ukuze wehlise i-UGR, nazi ezinye izindlela zereferensi yakho.
I-1) Ukuze ugweme ukufaka isibani endaweni yokuphazamiseka.
2) Ukusebenzisa izinto zokuhlobisa ezicwebezelayo eziphansi.
3) Ukunciphisa ukukhanya kwezibani.
