Ultraviolet lub teeb yog tsim nyob rau hauv lub mercury paug raj: ib tug quartz raj muaj ob electrodes thiab ib tug insulator tshem tawm nyob rau hauv ib tug inert gas hu ua mercury vapor. Mercury ncav cuag nws qhov siab tshaj plaws ntawm 254 nanometers, 310 nanometers thiab 366 nanometers, tsim hluav taws xob ntawm 200 thiab 400 nanometers. Quartz txiav tawm qis wavelengths thiab tsis xa cov hluav taws xob qis dua 230 nanometers.
Txhua lub atom muaj ib lub nucleus nrog ntau cov electrons ntab hauv lub voj voog ruaj khov nyob ib puag ncig nws. Los ntawm kev nce lub zog (hluav taws xob) electrons raug coj mus rau hauv qhov chaw siab dua. Txhua yam qhia tau hais tias muaj kev nyiam rov qab mus rau nws qhov qub. Lub electron yuav thim rov qab nyob rau hauv nws lub voj voog yav dhau los: lub zog tshaj tawm yog photon. Feem ntau siv ultraviolet teeb yog tsim los ntawm kev siv lub zog dielectric mercury arc teeb lossis MPMA teeb. Nws tuaj yeem ua tau ntev li ntawm ob peb millimeters mus rau ntau tshaj 2 meters. Lub neej ntev ntawm cov teeb no txawv ntawm 1000 txog 2500 teev. Lub teeb lub raj yog ua los ntawm quartz vim nws tsuas yog cov khoom siv uas xa cov teeb ci ultraviolet thaum ua haujlwm kub ntawm 6 txog 800 ° C. Cov hlab yuav nthuav me ntsis thiab muaj qhov kub ntawm qhov kub (1100 ° C). Cov electrodes yog tsim los ntawm tungsten: cov txheej txheem ntawm kev tsim lawv yog qhov nyuaj heev. Tungsten yog siv vim qhov kub ntawm qhov nkhaus tuaj yeem nce mus rau ntau dua 3000 ° C. Lub phaj molybdenum yog siv los txuas cov electrode thiab cov hlau, uas tuaj yeem nthuav ua ke nrog cov quartz. Thiab nws tseem tuaj yeem zam qhov siab voltage thaum rhuab. Lub teeb thaum kawg raug tshem tawm mus rau ceramic (los yog lwm yam) insulator. Vim tias cov khoom siv tam sim no feem ntau tsis txaus rau lub zog MPMA teeb, lub tshuab hloov pauv feem ntau yog siv rau UV teeb.
Ob hom yuav siv: induction thiab kho fais fab transformers. Standard ballast kuj tseem siv txog li 5 kW muaj peev xwm.
