Izibani ze-Gallium zisebenzisa insimbi ye-gallium noma izinhlanganisela zayo njengezinto ezikhanyayo futhi zinenani elibalulekile lesicelo emikhakheni ethile. Ngokungafani nemithombo yokukhanya evamile njengezibani ze-incandescent nama-LED, izibani ze-gallium ngokuvamile zikhiqiza ukukhanya ngokukhishwa komhwamuko we-gallium noma ukuvuswa kwezinhlanganisela ze-gallium, okuholela ezicini ze-spectral eziyingqayizivele kanye nezakhiwo ezibonakalayo.
Ngokwesakhiwo, izibani ze-gallium ngokuvamile zihlanganisa ingilazi evaliwe noma ishubhu le-quartz eligcwele igesi engasebenzi (njenge-argon) kanye nenani elincane le-gallium noma i-gallium compound (njenge-gallium nitride noma i-gallium phosphide). Uma i-electric current igeleza kuyo, ama-athomu e-gallium ajabulela{1}}isimo samandla aphezulu, bese eshintshela emuva esimweni esiphansi futhi akhiphe ukukhanya kobude obuthile be-wavenge. Kuye ngenhlanganisela ye-gallium, amalambu e-gallium angakhipha ukukhanya kwe-ultraviolet, okubonakalayo, noma kwe-infrared, ngamalambu e-gallium nitride (GaN){3}asekelwe e-gallium asebenza kahle ikakhulukazi kumaza amaza aluhlaza kanye ne-ultraviolet.
Amalambu e-Gallium asetshenziswa ngokuyinhloko ocwaningweni lwesayensi, ekuhlolweni kwezimboni, nasezindaweni zezokwelapha. Ekuhlaziyweni kwe-spectral, izibani ze-gallium, ngenxa yokuphuma kwazo kokukhanya okuzinzile kwe-monochromatic, zivame ukusetshenziswa njengemithombo yokulinganiswa kwe-wavelength, edlala indima ebaluleke kakhulu ekuhlolweni kokumuncwa kwe-athomu nokuhlaziywa kwe-fluorescence. Ekwenziweni kwe-semiconductor, amalambu e-Gallium UV asetshenziswa enqubweni yokuchayeka kwe-photoresist, lapho ubude bawo begagasi obufushane buvumela ukudalwa kwephethini yesekethe ecolekileyo. Ngaphezu kwalokho, ukuphuma kwezibani ze-UV zamalambu e-gallium nakho kulungele ukuvala inzalo nokubulala amagciwane, nakuba ukusebenza kahle kwawo ngokuvamile kuphansi kunalokho kwama-UV LED azinikele noma amalambu e-mercury.
Ngokuphawulekayo, izindleko eziphezulu zokukhiqiza nokunakekela amalambu e-gallium, kuhambisana nokushoda okulinganiselwe kwezinsiza ze-gallium, kunciphise ukusetshenziswa kwazo okusabalele. Kodwa-ke, ngokuthuthuka kobuchwepheshe obubanzi-be-bandgap semiconductor obufana ne-gallium nitride, imithombo yokukhanya emisha,{2}}esebenza kahle kakhulu esekelwe ezintweni ze-gallium ishintsha kancane kancane amalambu e-mercury endabuko, iba indlela entsha yokukhanyisa imvelo nokusebenza{3}okuphezulu. Ngokuzayo, ngokuthuthuka kwesayensi yezinto zokwakha, amandla ezibani ze-gallium emikhakheni eyengeziwe azophinde adedelwe.
