Isibane esiphezulu{{0}soxinzelelo lwemercury sisibane esikhupha igesi esikhupha ukukhanya okusekwe kukukhutshwa komphunga imekyuri. Isetyenziswa kakhulu kwimizi-mveliso, kwezonyango, nakwizicelo zokukhanyisa zangaphandle. Umgaqo wayo wokusebenza kukuba -i-arc yevoltage ephezulu ivuselela umphunga wemercury, ivelisa i-radiation ikakhulu kuluhlu lwe-ultraviolet. Le radiation ke iguqulwa ibe kukukhanya okubonakalayo yiphosphors ngaphakathi kwityhubhu yesibane.
Ubume obungundoqo besibane{0}}soxinzelelo lwemercury oluphezulu siqulathe ityhubhu yeglasi yequartz, i-electrodes, kunye nomphunga wemekyuri. Xa okwangoku idlula kwi-electrodes, umphunga we-mercury ngaphakathi kwi-tube i-ionized ukwenza i-plasma. Ii-electron zingqubana neeathom zemercury, zitshintshela kumanqanaba aphezulu amandla zize emva koko zikhuphe ukukhanya kwe-ultraviolet kwi-254 kunye ne-185 nanometers. Oku kukhanya kwe-ultraviolet kuvuyisa i-phosphors (efana ne-phosphors yomhlaba enqabileyo) egqunywe eludongeni lwetyhubhu, ivelisa ukukhanya okumhlophe okungumxube wemibala ephambili ebomvu, eluhlaza, kunye neblue. Ngenxa yokuba ukukhutshwa kufuna i-voltage ephezulu (ngokuqhelekileyo amawaka aliqela e-volts) ukuqalisa ukukhutshwa, ityhubhu yesibane izaliswe-ngexabiso elincinci le-argon okanye igesi ye-neon ukunciphisa umbane wokuqalisa.
Esi sibane sineempawu ezibalulekileyo: Okokuqala, siqhayisa ngokusulungekileyo kokukhanya okuphezulu, sifikelela ku-50{3}}60 lumens ngewathi nganye, ezodlula kude izibane ze-incandescent; okwesibini, iqhayisa ubomi obude, kunye nexesha eliqhelekileyo lokusebenza elidlula iiyure ze-10,000; kwaye okwesithathu, i-spectrum yayo igxininiswe kwi-blue-green band, iyenza ilungele izicelo apho unikezelo lombala lungabalulekanga kangako. Nangona kunjalo, isalathiso sayo sombala ophantsi (CRI) (malunga ne-40-60) kunye nokulibaziseka okubalulekileyo kokuqalisa (ukuthatha imizuzu ye-4-8 ukufikelela ekukhanyeni okuzinzile) ukunciphisa ukusetyenziswa kwayo kwezinye iindawo zangaphakathi.
Ngokwemigaqo yesicelo, izibane zoxinzelelo zemercury eziphezulu-ziqhele ukusetyenziswa kwiindawo ezifuna ukukhanya okufanayo kwindawo ebanzi, efana nezibane zendlela, amabala emidlalo, kunye neendawo zokusebenzela zasefektri. Imveliso yabo ye-UV ikwabenza babe luncedo kwiindawo ezinjengokufota kunye nokuvala inzala. Ngenkqubela phambili yetekhnoloji, izibane ze-metal halide kunye nee-LED ngokuthe ngcembe zithatha indawo yemveli ephezulu{3}}yoxinzelelo lwemercury izibane, kodwa le yokugqibela, ngenxa yetekhnoloji evuthiweyo kunye neenzuzo zeendleko, isagcina ukusetyenziswa kwayo kwizicelo ezithile.
Kwixesha elizayo, njengoko imithetho yokusingqongileyo iqinisa izithintelo kusetyenziso lwemekyuri,{0}izibane zoxinzelelo lwemercury eziphezulu zinokuphuma kancinci kancinci emarikeni. Nangona kunjalo, imigaqo yabo yobugcisa isabonelela ngesiseko esibalulekileyo sophuhliso lwemithombo yokukhanya yombane yanamhlanje.
