Xa abantu benesidingo sokuhamba ebusuku, kukhoukukhanya koluntu. Izibane zoluntu zanamhlanje zaqala ngokuvela kokukhanya kwe-incandescent. Ukukhanya koluntu kukhula kunye nophuhliso lwamaxesha, inkqubela phambili yenzululwazi kunye nobuchwepheshe kunye nokuphuculwa okuqhubekayo kwemigangatho yokuphila kwabantu. Ukusuka kubantu bafuna kuphela ukukhanya kwendlela yokukhangela imeko yendlela, ukunceda abantu ukuba bachonge ukuba ngaba indlela ihamba ngeenyawo okanye ingumqobo, ukunceda izithuthi kunye nabaqhubi bezithuthi ezingezizo iimoto bachonge iimpawu zabahambi ngeenyawo, njl.
Injongo esisiseko yokukhanyisa uluntu kukubonelela abaqhubi nabahambi ngeenyawo ngeemeko ezintle zokubonwa kunye nokubakhokela ukuba bahambe, ukuze kuphuculwe ukusebenza kakuhle kwezithuthi, ukunciphisa iingozi zendlela kunye nolwaphulo-mthetho ebusuku, kwaye kwangaxeshanye bancede abahambi ngeenyawo babone ngokucacileyo indawo engqongileyo. kwaye uchonge izalathiso. Ngophuhliso loqoqosho lwentlalo kunye nokuphuculwa okuqhubekayo kwemigangatho yokuphila yabantu, abantu abaninzi ngakumbi baya kwiindawo zokuzonwabisa zangaphandle, ukuthenga, ukubukela, kunye neminye imisebenzi ebusuku. Izibane zoluntu ezilungileyo zikwadlala indima ekutyebiseni ubomi, ukuphumelela kwezoqoqosho kunye nokwandisa umfanekiso wesixeko.
Ngokwembono yokukhanya kukawonke-wonke, iindlela zinokwahlulwa zibe ziindidi ezine: iindlela ezikhethekileyo zeenqwelo-mafutha, izitrato eziqhelekileyo, izitalato zorhwebo, neendlela zokuhamba ezisecaleni. Ngokuqhelekileyo, ukukhanya koluntu kubhekiselele ekukhanyeni okukhethekileyo koluntu kwiimoto. Phakathi kweenjongo ezininzi zokukhanyisa uluntu, ukubonelela ngeemeko ezibonakalayo ezikhuselekileyo nezikhululekileyo kubaqhubi bezithuthi zezokuqala.
Umthombo wokukhanyisa uluntu wawusisibane sesitrato ekuqaleni, kwaye emva koko kwafika ukukhanya kwe-mercury ephezulu, i-high-pressure sodium (HPS) ukukhanya, ukukhanya kwe-metal halide, ukukhanya okuphezulu kokugcina amandla, ukukhanya kwe-electrodeless, ukukhanya kwe-LED, njl. Phakathi kwemithombo yokukhanya yesitrato evuthiweyo, izibane ze-HPS zinobona buchule buphezulu bokukhanya, ngokuqhelekileyo zifikelela kwi-100 ~ 120lm/W, kunye nezibane ezinoxinzelelo oluphezulu ze-sodium ezingaphezulu kunoko. I-60% yemarike yokukhanyisa yoluntu iyonke e-China (malunga ne-15 yezigidi zezibane). Kwezinye iindawo zoluntu nakwiindlela zasemaphandleni, i-CFL ngowona mthombo wokukhanyisa, uthatha malunga ne-20% yemarike yezibane zoluntu. Izibane zemveli ze-incandescent kunye nezibane eziphezulu ze-mercury zoxinzelelo ziyacinywa.
