Ukukhanya nokufana okujwayelekile kwezibani ze-Parking Lot
Izincomo zamanje zedizayini ezivela ku-Illuminating Engineering Society of North America (IESNA) zokukhanyisa indawo yokupaka zitholakala enguqulweni yakamuva ye-RP-20 (2014).
Ukukhanya
Amanani okukhanyisa afana nezici ezibonakalayo kanye nezidingo zokukhanyisa eziyingqayizivele zendawo yokupaka zidinga ukunqunywa. I-RP-20 inikeza izincomo.
Ukufana
Ukufana kokukhanyisa (okuhunyushwe ekuboneni komuntu ukusatshalaliswa okufanayo kokukhanyisa kuyo yonke indawo yokupaka) kuvezwa njengesilinganiso sezinga eliphezulu lokukhanyisa ezingeni elincane lokukhanyisa. Izincomo zamanje ze-IESNA ngu-15:1 (yize kusetshenziswa u-10:1). Lokhu kusho ukuthi lapho ikalwa endaweni eyodwa yendawo yokupaka, ukukhanya kwayo kuphindwe izikhathi ezingu-15 kunokwenye indawo.
Isilinganiso sokufana esingu-15:1 noma 10:1 ngeke sikhiqize lokho abantu abaningi abakubiza ngokuthi ukukhanyisa okufanayo. Lokhu kuzoholela ezindaweni ezikhanyayo nezimnyama endaweni yokupaka. Ukungalingani okunjalo kungase kwenze abantu abangena emotweni bazizwe bengalondekile. Ngaphezu kwalokho, lezi zindawo ezimnyama zingakhuthaza ukuziphatha okungekho emthethweni.
Ukuntuleka kokukhanyisa okufanayo kuwumsebenzi wamalambu endabuko e-HID asetshenziswa ezindaweni zokupaka. Izibani ze-HID zikhiqiza ukukhanya nge-arc phakathi kwama-tungsten electrode ku-arc tube. Ishubhu ye-arc ingathathwa njengomthombo wokukhanya wephoyinti. Idizayini ye-luminaire iqondisa kabusha ukukhanya ekusabalaliseni okufunayo. Umphumela uba ukukhanyisa ukukhanya okuphezulu noma okunamandla kakhulu ngaphansi kwesibani se-HID, kodwa endaweni emnyama phakathi kwesibani esisodwa nesinye.
Ngokufika kwama-LED, inkinga yokufana ekukhanyeni kwendawo yokupaka ingaxazululwa ngendlela eyayinzima noma engenakwenzeka ngaphambi kwe-HID. Uma kuqhathaniswa namalambu e-HID, amalambu e-LED ahlinzeka ngokufana okuphezulu. Ukukhanya okukhishwa amalambu e-LED akukhiqizwa umthombo wokukhanya wephoyinti elilodwa (njenge-HID), kodwa ngama-LED ahlukene amaningi. Uma usebenzisa izibani ze-LED, leli qiniso ngokuvamile livumela isilinganiso esiphansi esiphezulu-ubuncane bokufana.
