Njengoba izidingo zokukhanyisa zangaphakathi ziyanda, izibani ezilula zophahla azisakwazi ukuhlangabezana nezidingo ezahlukahlukene. Izibani eziphansi nezibani zidlala indima ebalulekile ekwakhiweni kokukhanyisa kwendlu yonke, kungakhathaliseki ukuthi kungokokukhanyisa okuhlotshisiwe noma umklamo wesimanje ongenazo izibani eziyinhloko.
Umehluko phakathi kwezibani ezikhanyayo nezikhanyayo.
Okokuqala, izibani eziphansi kanye nezibani zokukhanyisa kulula kakhulu ukuzihlukanisa nokubukeka. Izibani eziphansi ngokuvamile zinemaski emhlophe eqandisiwe ebusweni obukhanyayo, okuwukwenza ukusabalala kokukhanya kufane, futhi izibani ezikhanyayo zifakwe izinkomishi noma amalensi akhanyayo, isici esivame kakhulu ukuthi umthombo wokukhanya ujulile kakhulu, futhi akukho mask. Kusukela esicini se-beam angle, i-beam angle yokukhanya okuphansi inkulu kakhulu kune-beam angle yokukhanya. Izibani eziphansi ngokuvamile zisetshenziselwa ukunikeza ukukhanya okubanzi, kanti i-beam angle ngokuvamile ingama-degree angu-70-120, okungokukhanya kwezikhukhula. Izibani eziphansi ngokuvamile zisetshenziselwa ukuhlinzeka ngokukhanya okugqamile, ukugeza izindonga ukuze kugqanyiswe izinto ngazinye, njengemidwebo yokuhlobisa noma izingcezu zobuciko. Kuphinde kusize ukudala umuzwa wokukhanya nobumnyama, okudala isikhala esifanele. I-beam angle ikakhulukazi ingama-degree angu-15-40. Uma kukhulunywa ngezinye izinkomba zokusebenza eziyinhloko lapho ukhetha izibani eziphansi kanye nezibani zokukhanyisa, kunezinye ezivamile njengamandla, ukugeleza kokukhanya, inkomba yokunikeza umbala, i-beam angle kanye nezinkomba ezimbili ezihlukile - umsebenzi wokulwa nokukhanya kanye nokushisa kombala.
Abantu abaningi, ngokuqonda i-anti-glare, bathi “izibani azikhazimli”, empeleni, lokhu akulungile neze. Noma yikuphi ukukhanya okuphansi noma ukukhanya okubonakalayo emakethe kunamandla kakhulu uma kungaphansi komthombo wokukhanya. “Anti-glare” kusho ukuthi awuzizwa ukukhanya okungemuva okunamandla uma ubheka isibani ohlangothini. Isibonelo, lolu chungechunge lwezibani ezikhanyayo zakudala lusebenzisa inethi yezinyosi kanye nezibonisi ukuze kuvinjelwe ukukhanya okukhanyayo futhi kusabalalise ukukhanya ngokulinganayo endaweni ezungezile.
Okwesibili, izinga lokushisa lombala linquma umbala wokukhanya kwesibani se-LED, esivezwa ku-Kelvin, futhi siholela endleleni esibona ngayo ukukhanya okukhushulwayo. Izibani ezifudumele zibukeka zikhululekile kakhulu, kuyilapho izibani ezimhlophe ezibandayo zivame ukubukeka zikhanya kakhulu futhi zingakhululekile. Izinga lokushisa lombala elihlukile lingasetshenziswa futhi ukukhiqiza imizwa ehlukene.
Okumhlophe okufudumele – 2000 kuya ku-3000 K
Iningi labantu lijabulela ukukhanya okukhululekile ezindaweni zabo zokuhlala. Uma ukukhanya kubomvu kakhulu, kulapho kudala khona isimo sengqondo esikhululekile. Izibani ze-LED ezimhlophe ezifudumele ezinokushisa kombala okufika ku-2700 K ukuze kukhanye okukhululekile. Lezi zibani zivame ukutholakala egumbini lokuphumula, endaweni yokudlela, noma kunoma yiliphi igumbi lapho ufuna ukuphumula khona.
Okumhlophe kwemvelo – 3300 kuya ku-5300 K
Ukukhanya okumhlophe kwemvelo kudala isimo esiqondile nesihle. Ngakho-ke kuvame ukusetshenziswa emakhishini, ezindlini zangasese nasemaphasishi. Lolu hlu lokushisa lombala lufanelekile futhi emahhovisi okukhanyisa.
Ihholo linokushisa okumhlophe kwemvelo
Okumhlophe okubandayo – kusuka ku-5300 K
Umbala omhlophe obandayo waziwa nangokuthi umbala omhlophe okhanyayo. Ufana nokukhanya kwasemini ngesikhathi sasemini. Umbala omhlophe obandayo ukhuthaza ukugxilisa ingqondo ngakho-ke ulungele izindawo zokusebenza ezidinga ubuhlakani nokugxila kakhulu.
