Ukukhanya kunye nomgangatho ofanayo wokukhanyisa kwiLoti yokuPaka
Iingcebiso zoyilo lwangoku ezivela kwi-Illuminating Engineering Society yaseMntla Melika (IESNA) yokukhanyisa indawo yokupaka ifumaneka kwinguqulelo yamva nje ye-RP-20 (2014).
Ukukhanya
Amaxabiso okukhanyisa ahambelana neempawu ezibonakalayo kunye neemfuno zokukhanyisa ezizodwa kwindawo yokupaka kufuneka zimiselwe. I-RP-20 inika iingcebiso.
Ukufana
Ukukhanya okufanayo (okuguqulelwe kwimbono yabantu yokusabalalisa okufanayo kokukhanyisa kuyo yonke indawo yokupaka) ibonakaliswe njengomlinganiselo wezinga eliphezulu lokukhanyisa kwinqanaba elincinci lokukhanyisa. Ingcebiso ye-IESNA yangoku yi-15: 1 (nangona i-10: i-1 idla ngokusetyenziswa). Oku kuthetha ukuba xa kulinganiswa ummandla othile wendawo yokupaka, ukukhanya kwayo kuphindwe izihlandlo ezili-15 kunomnye ummandla.
Umlinganiselo ofanayo we-15: 1 okanye 10: 1 awuyi kuvelisa into abantu abaninzi abayibiza ngokuba yi-uniform illumination. Oku kuya kubangela iindawo eziqaqambileyo nezimnyama kwindawo yokupaka. Ukungalingani okunjalo kunokwenza abantu abangena emotweni bazive bengakhuselekanga. Ukongezelela, le mimandla emnyama inokukhuthaza ukuziphatha okungekho mthethweni.
Ukunqongophala kokufana kokukhanyisa ubukhulu becala ngumsebenzi wezibane eziqhelekileyo ze-HID ezisetyenziswa kwiindawo zokupaka. Izibane ze-HID zivelisa ukukhanya nge-arc phakathi kwe-tungsten electrode kwi-tube ye-arc. Ityhubhu ye-arc inokuthathwa njengomthombo wokukhanya. Uyilo lwe-luminaire lubuyisela ukukhanya kwi-distribution oyifunayo. Isiphumo sivame ukukhanyisa ukukhanya okuphezulu okanye ukukhanya okuphezulu ngokuthe ngqo phantsi kwesibane se-HID, kodwa kwindawo emnyama phakathi kwesibane esinye kunye nesinye.
Ngokufika kwee-LEDs, ingxaki yokufana kwindawo yokupaka izibane zokupaka ingasombululwa ngendlela enzima okanye engenakwenzeka ngaphambi kwe-HID. Xa kuthelekiswa nezibane ze-HID, izibane ze-LED ngokwendalo zibonelela ngokufana okuphezulu. Ukukhanya okukhutshwe zizibane ze-LED akuveliswa ngumthombo owodwa wokukhanya (njenge-HID), kodwa ngee-LED ezininzi ezicacileyo. Xa usebenzisa izibane ze-LED, le nyaniso ihlala ivumela umlinganiselo ophantsi ophantsi wokufana.
