Vim li cas txoj kev teeb maj mam teeb?

Cov teeb pom kev zoo feem ntau yog cov teeb uas muaj mercury tsawg
Lub teeb mercury uas tsis tshua muaj siab yog siv cov mercury uas tsis tshua muaj siab mercury vapor hauv cov txheej txheem tso tawm kom tawg lub teeb ultraviolet, kom cov phosphor emitted pom lub teeb pom kev.

Muaj ob lub filaments hauv lub teeb fluorescent. Cov filament yog coated nrog cov khoom siv hluav taws xob emission terylene carbonate (barium carbonate, strontium carbonate thiab calcium carbonate), feem ntau hu ua electron hmoov.

Nyob rau hauv AC voltage, lub filament hloov ua raws li cathode thiab anode.
Sab hauv phab ntsa ntawm lub teeb yog coated nrog phosphor. Lub raj yog ntim nrog argon roj ntawm 400Pa mus rau 500Pa siab thiab me me ntawm mercury.

Tom qab siv hluav taws xob, cov kua mercury evaporates mus rau hauv mercury vapor nrog lub siab ntawm 0.8 Pa. Nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb, mercury atoms txuas ntxiv zoo siab los ntawm lub xeev qub mus rau hauv lub xeev zoo siab, thiab ces spontaneously hloov. mus rau hauv av, thiab radiate ultraviolet lub teeb nrog ib tug wavelength ntawm 253.7nm thiab 185nm (lub ntsiab ncov wavelength yog 253.7nm, suav txog li 70-80% ntawm tag nrho lub zog radiant; Lub phosphor absorbs ultraviolet hluav taws xob thiab emits pom lub teeb.
Vim li ntawd, txoj kev teeb maj mam teeb
