Indlela yokunciphisa i-UGR?
Ilitha lokukhubazeka litha elinciphisa ukusebenza ngokubonakalayo kunye nokubonakala, kwaye lihlala likhatshwa kukungakhululeki. Ubukhulu becala kubangelwa ukukhanya okulahlekileyo okuvela kwimithombo yokukhanya ekhanyayo engena kwiso kwibala lokujonga, ukusabalalisa ngaphakathi kwamehlo kunye nokunciphisa ukucaca komfanekiso kunye nokungafani kwezinto kwi-retina. Ilitha lokukhubazeka lilinganiswa ngomlinganiselo wokubonakala komsebenzi phantsi kwendawo yokukhanyisa enikiweyo ukuya ekubonakaleni kwayo phantsi kweemeko zokukhanyisa zesalathiso, ezibizwa ngokuba yi-disability glare factor. (DGF)
Ilitha elingonwabanga, elikwabizwa ngokuba yi "psychological glare", libhekisa kwilitha elibanga ukungonwabi okubonakalayo kodwa lingabangeli kuncipha kokubonakala.
Ezi ntlobo zimbini ze-glare zibizwa ngokuba yi-UGR (I-Unified Glare Rating), okanye ixabiso elilinganayo le-glare, enye yezinto eziphambili zokuvavanya umgangatho wokukhanyisa ekuyilweni kokukhanyisa. Ezi ndidi zimbini zokulitha zinokuvela ngaxeshanye, okanye zisenokubonakala zingatshatanga. I-UGR efanayo ayiyona nje ingxaki ebonakalayo, kodwa kunye nengxaki yoyilo kunye nesicelo. Ke indlela yokunciphisa i-UGR ekusebenzeni yingxaki ephambili.
Ngokubanzi, isibane senziwe ngezindlu, abaqhubi, imithombo yokukhanya, i-lens okanye iglasi. Kwaye ekuqaleni koyilo lwesibane, kukho iindlela ezininzi zokulawula ixabiso le-UGR, njengokulawula ukukhanya kwemithombo yokukhanya, ukubonelela nge-anti-glare design kwi-lens, okanye ukongeza ikhaka elikhethekileyo ukukhusela ukuchithwa.
Ngaphakathi kwishishini, iyavuma ukuba akukho UGR ukuba isibane sombane jikelele sihlangabezana nezi meko zilandelayo.
1) I-VCP (ithuba lokuthuthuzela okubonwayo) ingaphezulu kwama-70.
2) Xa ujonge ngokuthe nkqo okanye ngokuthe tye kwigumbi, umlinganiselo wokukhanya kwesibane esiphezulu (esona siqaqambileyo yi-6.5 cm²) ukuya kumndilili wokukhanya yi-5:1 kwi-engile ye-45deg, 55deg, 65deg, 75deg kunye ne-85deg.
3) Isidingo sokuphepha ukumenyeza okungathandekiyo kungakhathaliseki ukujonga ngokuthe nkqo okanye ecaleni xa isibane kunye nomgca othe nkqo kwitheyibhile kwii-angles ezahlukeneyo zokukhanya okuphezulu akunakudlula itshathi engezantsi.
Ke ukuze unciphise i-UGR, nazi ezinye iindlela zereferensi yakho.
1) Ukuphepha ukufaka isibane kwindawo yokuphazamiseka.
2) Ukusebenzisa izinto zokuhombisa iglosi ephantsi.
3) Ukunciphisa ukukhanya kwezibane.
