Ib yam li ib tug yuav nug, dab tsi yog sab hauv ntawm lub teeb fluorescent ballast?

Qhov no teeb muaj iav cev ntim nrog cov roj inert (feem ntau yog argon) ntawm qhov tsis tshua muaj siab. Ntawm txhua sab ntawm lub cev Koj yuav pom tungsten electrode. Cov ballast tswj AC zog rau cov electrodes. Laus teeb siv ib tug starter kom tau teeb mus.

Tsis tas li ntawd, cov teeb fluorescent puas muaj tshuaj lom? ?Compact fluorescent teeb qhov muag teev (CFLs) txuag ntau lub zog thiab kav ntev txog 10 npaug ntev dua li niaj zaus qhov muag teev . Txij li CFLs muaj me me ntawm mercury , uas tuaj yeem ua rau muaj kev phom sij rau ib tus neeg noj qab haus huv yog tias noj lossis nqus tau, nws yog ib qho tseem ceeb uas yuav tsum tau ua thiab pov tseg ntawm CFLs kom raug.

Ua raws li qhov xav tau, lub teeb fluorescent yog dab tsi?

A fluorescent Lub teeb muaj ib lub iav raj uas muaj ib tug sib tov ntawm argon thiab mercury vapour. Cov hlau electrodes ntawm txhua qhov kawg yog coated nrog lub ntiaj teb alkaline oxide uas muab cov hluav taws xob tawm yooj yim. Thaum tam sim no ntws los ntawm cov pa roj ntawm cov electrodes, cov roj yog ionized thiab emits ultraviolet hluav taws xob.

Cov teeb fluorescent no puas muaj cov khoom qub?

Lub hauv paus keeb hauv a fluorescent teeb yog ib lub khob kaw cev . Cov cev muaj me me ntawm mercury thiab ib qho roj inert, feem ntau yog argon, khaws cia nyob rau hauv qhov tsis tshua muaj siab. Raws li cov electrons thiab charged atoms txav mus los cev , ib co lawv yuav sib tsoo nrog cov gaseous mercury atoms.
