Ipharamitha yezengqondo ekala ukusabela kokuzithoba kokukhanya okukhishwa idivayisi yokukhanyisa endaweni ebonakalayo yasendlini emehlweni omuntu, futhi inani lalo lingabalwa ngefomula yenani elicwebezelayo elihlanganisiwe le-CIE ngokuya ngezimo zokubala ezishiwo.
Izindinganiso zasekuqaleni zedizayini yokukhanyisa ezimbonini nasezindaweni zomphakathi zicacisa ukuthi ukukhanya okuqondile kokukhanya okuvamile kwasendlini kunqunyelwe ngokuya ngejika elilinganiselwe lokukhanya. Le ndlela yokukhawulela ingeyokukhanya kwesibani esisodwa kuphela, futhi ayikwazi ukumela umphumela ocwebezelayo okhiqizwa yizo zonke izibani ekamelweni. Ngakho-ke, i-CIE ibeka phambili ifomula yokubala yenani elicwebezelayo elihlanganisiwe (UGR) ngesisekelo sokuhlanganiswa kwamafomula okubala okuxhophayo emazweni ahlukahlukene. Ifanele umklamo wokukhanyisa ojwayelekile wekamelo elilula elifana ne-cube. Izibani zihlelwe ngokulinganayo ngezikhathi ezilinganayo, futhi izibani ziyi-symmetrical kabili nokusabalalisa ukukhanya.
I-UGI-R yezibani ze-LED ihlukaniswe ngale ndlela elandelayo:
| Inani | Umuzwa |
| 25-28 | Ayibekezeleleki |
| 22-25 | Angikhululekile |
| 19-22 | Izinga elibekezelelekayo lokuxhopha |
| 16-19 | Izinga elamukelekayo lokuxhopha, elifana namahhovisi namakilasi adinga ukukhanya isikhathi eside, lifanele leli zinga. |
| 13-16 | Akuzwakali |
| 10-13 | Angikuzwa ukubenyezela |
| ＜10 | Imikhiqizo yezinga eliphezulu yamagumbi okuhlinzela esibhedlela |
Yebo, i-UGR ayilona inani lomkhiqizo owodwa, futhi ihlobene nendawo yokusetshenziswa kwezibani ezikhanyayo eziholayo.
Isibonelo, lapho ukukhanya kwegumbi kuphansi, i-UGR ephezulu. Umgomo ulula kakhulu: uma umehluko omkhulu phakathi kokukhanya okuzungezile nokukhanya kwezibani, kukhulu ukungakhululeki kwamehlo. Yingakho izindawo ezinokukhanya okuphansi, njengamabha noma ama-KTV, ngokuvamile zisebenzisa izibani ezikhanyayo nezikhanyayo esikhundleni sokulenga isibani esikhulu ngaphakathi.
Ngalesi sikhathi, inkinga ifika. Njengenkampani ekhanyisayo, awazi ukuthi iyiphi indawo amakhasimende akho abeka kuyo izibani, ngakho-ke yini okufanele uyenze? Njengoba kungenakwenzeka ukulawula imvelo, khona-ke senza i-UGR yomkhiqizo ngokwawo ngaphansi kwe-19/16/13/10, ukuze ingadali umonakalo emehlweni amakhasimende.
Ngakho-ke njengomthengi ojwayelekile ungakhetha kanjani izibani ezifanele eziholelekile? Futhi kulula kakhulu, ungakhetha amalambu aphansi ugr 19 aneshidi le-prism lefilimu elilwa nokucwazimula elincane.
Kungani i-UGR19? Ngoba i-UGR inesici, okungukuthi, kulula ukunciphisa kusuka ku-25 kuya ku-19, kodwa kunzima kakhulu ukunciphisa kusuka ku-19 kuya ku-10. Uma ucabanga ukuthi usebenzisa amandla aphindwe kabili kuphela ukusuka ku-25 kuya ku-19, ukusuka ku-19 kuya ku-16 May kubiza izikhathi ezi-5 kakhulu, futhi intengo izobiza kakhulu. Kungakho ngincoma i-UGR19 njengenketho engabizi kakhulu.
