Mabone a likoloi hangata a entsoe ka likarolo tse tharo: lebone la lebone, sebonela-moea le seipone se ts'oanang (seipone sa astigmatism).
1. tleloubu
Li-bulbs tse sebelisoang maboneng a likoloi ke li-incandescent bulbs, halogen tungsten bulbs, mabone a macha a khanyang a phahameng a arc joalo-joalo.
(1) Tleloubu ea incandescent: khoele ea eona e entsoe ka terata ea tungsten (tungsten e na le ntlha e phahameng ea ho qhibiliha le khanya e matla). Nakong ea tlhahiso, e le ho eketsa bophelo ba tšebeletso ea tleloubu, tleloubu e tletse khase ea inert (naetrojene le motsoako oa eona oa likhase tse sa sebetseng). Sena se ka fokotsa mouoane oa terata ea tungsten, sa eketsa mocheso oa khoele, 'me sa ntlafatsa katleho e khanyang. Lebone le tsoang tleloubung ea incandescent le na le 'mala o mosehla.
(2) Lebone la Tungsten halide: Lebone la lebone la Tungsten halide le kenngoa ka har'a khase ea inert ka har'a ntho e itseng ea halide (joalo ka iodine, chlorine, fluorine, bromine, joalo-joalo), ho sebelisoa molao-motheo oa tungsten halide recycling reaction, ke hore, tungsten ea gaseous e mouoane ho tloha filament e kopana le halogen ho hlahisa tungsten halide e sa tsitsang, e fetelang sebakeng sa mocheso o phahameng haufi le khoele, 'me e senngoa ke mocheso, e le hore tungsten e khutlisetsoe khoeleng. Halogen e lokollotsoeng e ntse e tsoela pele ho hasana le ho nka karolo tšebetsong e latelang ea potoloho, kahoo potoloho e tsoela pele, ka hona e thibela ho tsoa mouoane oa tungsten le ho fifala ha tleloubu. Boholo ba lebone la lebone la tungsten halogen le nyane, khetla ea bulb e entsoe ka khalase ea quartz e nang le mocheso o phahameng oa mocheso le matla a phahameng a mochini, tlas'a matla a tšoanang, khanya ea lebone la tungsten halogen ke makhetlo a 1.5 ho feta a lebone la incandescent, 'me bophelo ke 2 ho 3 makhetlo a ho feta.
(3) Lebone le lecha la arc le khanyang haholo: Lebone lena ha le na likhoele tsa setso ka tleloubung. Ho e-na le hoo, li-electrode tse peli li kenngoa ka har'a tube ea quartz. The tube e tletse xenon le trace metals (kapa halides tšepe), 'me ha ho na le lekaneng arc gagamalo ka eleketrode (5000 ~ 12000V), khase e qala ho ionize le ho tsamaisa motlakase. Liathomo tsa khase li boemong bo thabileng 'me li qala ho hlahisa leseli ka lebaka la phetoho ea matla a lielektrone. Ka mor'a 0.1s, mouoane o monyenyane oa mercury o fetoha mouoane pakeng tsa li-electrode, 'me matla a matla a fetisetsoa hang-hang ho mercury vapor arc discharge, ebe o fetisetsoa lebone la halide arc ka mor'a hore mocheso o phahame. Ka mor'a hore leseli le fihle mocheso o tloaelehileng oa ho sebetsa oa tleloubu, matla a ho boloka ho tsoa ha arc a tlaase haholo (hoo e ka bang 35w), kahoo 40% ea matla a motlakase a ka bolokeha.
