Kuyini ukukhanya komgwaqo welanga elinezinzwa?
I-solar street light enezinzwa ukukhanya komgwaqo okusebenzisa amandla elanga ukuze kunikeze amandla futhi kunenzwa. Lezi zibani zasemgwaqweni ngokuvamile zinenzwa yokukhanya elungisa ngokuzenzakalelayo ukukhanya ngokuvumelana nokukhanya okuzungezile, ngaleyo ndlela yonga amandla.
Isibonelo, phakathi nosuku, inzwa yokukhanya izwa ukuthi ukukhanya kuphezulu futhi ithumela isignali kusilawuli sesibani somgwaqo ukuze sinciphise ukukhanya. Ebusuku noma ezinsukwini eziguqubele, inzwa yokukhanya izwa ukuthi amandla okukhanya aphansi futhi ithumela isilawuli isilawuli ukuze sandise ukukhanya kokukhanya komgwaqo.
Isebenza kanjani?
Izibani zasemgwaqweni zelanga ezinezinzwa kulula ukuzifaka futhi zidinga ukulungiswa okuncane, futhi ngokuvamile zinikwa amandla ngamaphaneli elanga. Amaphaneli elanga aqoqa amandla elanga futhi awaguqule abe ugesi, ogcinwa kumabhethri wesibani sasemgwaqweni. Ilambu le-solar street libe selisebenzisa ugesi ogciniwe ukuze linikeze ukukhanya ebusuku.
Inzwa yokuhamba ye-PIR
Izinzwa ezinyakazayo ze-PIR zezibani zelanga ziyi-PIR (human infrared) izinzwa ezinyakazayo ezifakwe kumalambu asemgwaqweni welanga. Izinzwa zokunyakaza ze-PIR zizwa ukuthi abantu noma izinto ziyahamba futhi zithuthukisa ukuphepha ngokulungisa ukukhanya kwesibani somgwaqo.
Isibonelo, uma inzwa yokunyakaza ye-PIR izwa umuntu odlulayo, ukukhanya komgwaqo kuzokwandisa ukukhanya ukuze kunikeze ukukhanya okwanele ukuze kuvinjwe abantu ukuthi bangawi. Uma ukunyakaza kunyamalala, ukukhanya komgwaqo kunciphisa ngokuzenzakalelayo ukukhanya kwakho ukuze konge amandla.
Izinzwa ezikhanyayo
Inzwa yokukhanya kwelanga iyinzwa yokukhanya efakwe ekukhanyeni komgwaqo welanga. Inzwa yokukhanya izwa ukushuba kokukhanya okuzungezile futhi ilungise ukukhanya kwesibani somgwaqo ngokuya ngamandla okukhanya.
Inzwa yokushisa
Inzwa yezinga lokushisa izwa izinga lokushisa elizungezile futhi ilungise ukukhanya kwesibani somgwaqo ngokuya ngokushintsha kwezinga lokushisa.
Isibonelo, esimweni sezulu esibandayo, inzwa yezinga lokushisa izwa ukuthi izinga lokushisa elizungezile liphansi futhi ithumela isignali kusilawuli sesibani somgwaqo ukuze kwandiswe ukukhanya kwesibani somgwaqo ukuze sinikeze ukukhanya okwengeziwe kubantu. Esimweni sezulu esifudumele, inzwa yezinga lokushisa izwa ukuthi izinga lokushisa elizungezile liphezulu bese ithumela isignali kusilawuli ukuze sinciphise ukukhanya kwesibani somgwaqo ukuze konge amandla.
