Isibonisi sibhekisela kusibonisi esisebenzisa isibani sephoyinti njengomthombo wokukhanya futhi esidinga ukukhanya kwebanga elide. Iwuhlobo lwedivayisi ekhanyayo. Ukuze kusetshenziswe amandla okukhanya alinganiselwe, isibonisi sokukhanya sisetshenziselwa ukulawula ibanga lokukhanya nendawo yokukhanyisa yendawo eyinhloko. Amathoshi amaningi akhanyayo asebenzisa izibonisi.
Imingcele yejiyomethri yesibonisi ikakhulukazi ihlanganisa okulandelayo, njengoba kukhonjisiwe emfanekisweni:
· Ibanga H phakathi kwesikhungo somthombo wokukhanya kanye nokuvuleka kwesibonisi
· Idayamitha yokuvula ephezulu yesibonisi D
· I-engeli yokuphuma ekhanyayo B ngemva kokucabangisisa
· I-engeli yokukhanya yokuchitheka A
· Ibanga le-Irradiation L
· Ububanzi bendawo emaphakathi E
· Ububanzi bebala F bokukhanya okuchithekile
Inhloso yesibonisi kusistimu ye-optical iwukuqoqa futhi kukhiphe ukukhanya okuhlakazeke nxazonke ohlangothini olulodwa, nokufinya ukukhanya okubuthakathaka kube ukukhanya okuqinile, ukuze kufezwe injongo yokuqinisa umphumela wokukhanyisa nokwandisa ibanga lomsebe. Ngokuklanywa kwendawo yenkomishi ekhanyayo, i-engeli ekhipha ukukhanya, i-floodlight/concentration ratio, njll. yethoshi ingalungiswa. Ngokwethiyori, lapho kujula ukujula kwesibonisi kanye nokuvuleka kwendawo enkulu, kuqina amandla okuqoqa ukukhanya. Kodwa-ke, ekusebenzeni okungokoqobo, amandla okuqoqa ukukhanya akulungile ngempela. Ukukhetha kufanele futhi kwenziwe ngokuya ngokusetshenziswa kwangempela komkhiqizo. Uma kudingekile Ukuze ukhanyise ibanga elide, ungakhetha ithoshi elinokukhanya okujiya okuqinile, kuyilapho ekukhanyisweni kwebanga elifushane, kufanele ukhethe ithoshi eline-floodlight engcono (ukukhanya okugxilile okunamandla kukhanyisa amehlo futhi awukwazi ukubona into ngokucacile) .
Isibonisi siwuhlobo lwesibonisi esisebenza ekukhanyeni kwebanga elide futhi sinokubukeka okumise okwenkomishi. Ingasebenzisa amandla okukhanya alinganiselwe ukuze ilawule ibanga lokukhanya nendawo yokukhanya yendawo eyinhloko. Izinkomishi ezibonisa izinto ezihlukene kanye nemiphumela yenqubo zinezinzuzo zazo kanye nokubi. Izinhlobo ezijwayelekile zezibonisi emakethe ikakhulukazi izibonisi ezicwebezelayo nezibonisi ezibunjiwe.
Isibonisi esicwebezelayo:
a. Udonga lwangaphakathi lwenkomishi ye-optical lufana nesibuko;
b. Ingenza ithoshi likhiqize indawo emaphakathi ekhanya kakhulu, futhi ukufana kwebala kubi kancane;
c. Ngenxa yokukhanya okuphezulu kwendawo emaphakathi, ibanga lokushiswa kwemisebe likude kakhulu;
Isibonisi esibunjiwe:
a. Ingaphezulu lenkomishi yekhasi lewolintshi lishwabene;
b. Indawo yokukhanya ifana kakhulu futhi ithambile, futhi ukuguquka ukusuka endaweni emaphakathi kuya ku-floodlight kungcono, okwenza okuhlangenwe nakho kwabantu okubonakalayo kube ntofontofo kakhulu;
c. Ibanga lokushiswa kwemisebe liseduze;
Kungabonakala ukuthi ukukhethwa kohlobo lwesibonisi sethoshi kufanele futhi kukhethwe ngokuya ngezidingo zakho.
