Lebone le phahameng{{0}lebone la khatello ea mercury ke lebone le tloaelehileng la ho lahla-lebone la khase e matla. Molao-motheo oa ts'ebetso ea eona ke ho hlasimolla mouoane oa mercury ka har'a-voltage arc e phahameng ho hlahisa leseli la ultraviolet, le fetoloang leseli le bonahalang ke phosphor. Kaho ea eona e hloka moralo o nepahetseng le tlhahiso ea likarolo tse ngata tsa bohlokoa ho netefatsa ts'ebetso e khanyang le e tsitsitseng.
Likarolo tsa mantlha tsa lebone le phahameng-li kenyelletsa tšupu e ntšang metsi, li-electrode, enfelopo ea khalase, ballast, le phosphor coating. The discharge tube ha e le hantle e entsoe ka khalase ea quartz ka lebaka la ho hanyetsa mocheso o phahameng-le mahlaseli a mahlaseli a kotsi. The tube e tletse tekanyo e loketseng ea mouoane oa mercury le khase e sa sebetseng (e kang argon). Ha hona joale e sebelisoa, mouoane oa mercury oa fetoha mouoane, o etsa arc mme o lokolla mahlaseli a ultraviolet. Li-electrode hangata li entsoe ka li-tungsten filaments 'me li koahetsoe ka elektrone-emitting material (joalo ka barium oxide) ho fokotsa motlakase oa ho qala le ho boloka arc e tsitsitseng.
Enfelopo ea khalase e sireletsa tube ea ho qhala ho tsoa tšusumetsong ea kantle ea tikoloho. Mehlala e meng e boetse e na le seaparo sa phosphor leboteng le ka hare la enfelopo, e fetolang leseli la ultraviolet le hlahisoang ke mouoane oa mercury hore e be khanya e pharaletseng ea khanya e bonahalang, ho ntlafatsa katleho ea mabone. The ballast ke karolo ea bohlokoa ea lebone le phahameng-le khatello ea mercury. E fokotsa hona joale mme e fana ka matla a phahameng a matla a hlokahalang bakeng sa ho qala, ho netefatsa hore lebone le sebetsa ka mokhoa o tsitsitseng.
Nakong ea ts'ebetso ea tlhahiso, ho tiisoa ha tube ea ho ntša ho bohlokoa, ho netefatsa hore khatello ea mouoane oa mercury e lula e le ka har'a sebaka se nepahetseng (ka tloaelo 1-5 atmospheres) mocheso o phahameng. Boemo ba Electrode le ho nepahala ha tjheseletsa ho ama ka kotloloho botsitso ba arc, ha ho ts'oana ha phosphor ho etsa qeto ea ho hlahisa mebala ea leseli.
Kaho ea -mabone a mercury a phahameng a kopanya lisebelisoa tsa mahlale, theknoloji ea vacuum, le moralo oa mahlo. Ntlafatso ea sebopeho e ama bophelo ba mabone ka kotloloho, matla a khanyang, le tlhahiso ea mebala. Leha theknoloji ea LED e nkile sebaka sa mabone a mercury lilemong tsa morao tjena, mabone a phahameng-a ntse a boloka bohlokoa ba mabone a liindasteri le kantle ka lebaka la khanya ea ona e phahameng le litšobotsi tse ikhethang tsa spectral.
