Cov yees duab hauv qab no hais txog cov roj fluorescent tube ntau lawm yog qhov uas kuv tau nyiam tshaj plaws los txog rau txhua qhov pom hauv Yuav ua li cas yog nws ua tiav.
Ib txoj haujlwm tseeb ntawm kev kos duab ntawm lub cov kab ntau lawm.
Kev ua haujlwm ntawm lub raj tau piav qhia hauv daim yeeb yaj kiab, sab hauv yog them nrog phosphor uas yog dab tsi ua kom pom kev thaum cov mercury poob uas tau tshaj tawm yog ionized. Tab sis cia mus rau hauv ntau dua kom meej
Xyoo 1909, tus txiv neej Fabkis George Claude suav tias Fabkis Thomas Edison tau tsim lub teeb neon nrog cov hluav taws xob tso hluav taws xob rau roj inert.
Cov kauj ruam raug:
- Cov yas txhawm rau ntxuav nrog dej kub kom tshem tawm impurities,
- Lub raj yog tom qab ntawd rhaub mus rau qhov xav tau los ntawm khoov lub khob.
- Ib txheej txheej phosphor yog thov rau sab hauv ntawm cov hlab leeg. Cov phosphor yog ib lub uas tawm lub teeb ci, hloov pauv cov duab hluav taws xob ultraviolet uas tau tsim tawm los ntawm cov khoom hluav taws xob ionization.
- Tshaj cov phosphorus yog muab tshem tawm, nws yog kaw thiab cov khoom siv hluav taws xob,
- nrog kua hauv lub ntsiab ntawm lub cathode uas tawm cov hluav taws xob thaum sov.
- Thaum kawg cov pa tawm thiab tawm qee qhov kev nqus ntawm mercury yog qhia tias tsim nyog rau txhua yam haujlwm
Thaum kawg, nws yog ib qho txheej txheem nyuaj txawm tias muaj tshwm sim thaum ntxov xyoo pua 20 thiab tseem ua tau zoo tib yam los txog niaj hnub no. Cov ntsiab lus nthuav dav txog cov txheej txheem tsim tawm yog cov xov txheej, lub log uas txhua qhov coj los sim thiab lawv qhov kev sib khi
Txhua yam no thiab cov ntsiab lus uas peb tsis tau muab tso rau koj tuaj yeem pom lawv kom zoo hauv video.
Nws tsis yog cov khoom lag luam zoo nkauj feem ntau muaj thiab me ntsis ntawm qhov me me Kuv xav tias lawv yuav raug rho tawm, tab sis daim vis dis aus tsim nyog saib.
Yog tias koj xav paub ntau ntxiv txog kev paub vim li cas lawv ua haujlwm, Kuv tso koj ob kab ntawv txuas
