Lub teeb: li cas teeb ua haujlwm

Cov hnub no, teeb raj tau siv nyob rau ntau qhov chaw, ob sab hauv thiab sab nraud. Vim tias lawv tau siv tau, hloov tau, thiab pab tau, lawv feem ntau tau xaiv ntau rau ntau yam ntawm cov haujlwm. Kab lus no nkag mus rau hauv kev nthuav dav zoo txog cov teeb pom kev, nrog rau lawv cov haujlwm yooj yim, ntau hom, qhov zoo, thiab yuav ua li cas xaiv qhov zoo tshaj plawsLub teebrau koj cov kev xav tau.

Tus thiab vim li casTeeb Tsoob

Teeb lub teeb ua haujlwm vim tias muaj kev physics thiab chemistry ua haujlwm. Gases zoo li argon, krypton, thiab neon feem ntau siv hauv cov raj teeb. Cov roj av no tseem ceeb heev rau cov txheej txheem ntawm kev muab lub teeb. Cov roj muab tawm lub zog hauv daim ntawv ntawm photons thaum hluav taws xob hluav taws xob ntws los ntawm nws. Cov phosphor txheej, uas yog tsim los ntawm cov ntaub ntawv xws li calcium, barium, thiab strontium, muab tawm pom lub teeb thaum lub zog no nws. Tag nrho cov txheej txheem ua kom paub tseeb tias lub teeb mus txhua txoj kev raws lub raj, uas yog vim li cas lawv tau zoo rau cov chaw ntev. Lub ntsuas kub ntawm lub teeb kuj tseem tuaj yeem hloov pauv raws li cov phosphor uas siv. Qhov no txhais tau tias cov cua tuaj yeem hloov pauv kom haum koj cov kev xav tau.
Tsis tas li ntawd, kev nce qib hauv thev naus laus zis tau ua rau muaj peev xwm ua kom muaj zog fluorescentTeeb Tsoobyuav tsum tau tsim. Cov teeb pom kev siv hluav taws xob tsawg thaum tseem ua kom ci. Tsis tsuas yog ua qhov kev pab txo hluav taws xob cov nqi hluav taws xob, nws kuj ua rau muaj qhov sib txawv loj hauv kev txo cov pa roj carbon. Thaum LED Tube Teeb tau tawm los, lawv txawm muaj lub zog zoo dua vim tias lawv ntev dua thiab siv lub zog ntev dua. Lawv kuj muab lub teeb tam sim ntawd, tsis zoo li cov roj fluorescent tsoos tsho thiab cov uas xav tau sijhawm sov.

Dab tsi ua rau aLub teeb

Feem ntau cov raj teeb muaj ntau qhov chaw uas ua haujlwm ua ke los ua kom tag nrho cov haujlwm. Qee qhov no yog:
Lub raj iav raj: cia qhov chaw muaj kev nyab xeeb thiab puag ncig cov pa.
Muaj cov electrodes ntawm ob qho kawg ntawm cov xaim uas pab lub hluav taws xob tshiab ntws.
Phosphor txheej: npog sab hauv ntawm lub raj thiab hloov lub teeb cdaviolet rau hauv pom lub teeb.
Ballast tswj kev ntws ntawm hluav taws xob thiab muab lub teeb qhov hluav taws xob nws yuav tsum tau tig.
Los ntawm kev nkag siab cov ntu no, koj tuaj yeem nkag siab zoo dua li cas lub teeb ua haujlwm thiab vim li cas lawv thiaj li muaj kev xaiv zoo dua lwm cov teeb pom kev zoo. Piv txwv li, cov ballast tsis tsuas yog ua kom paub tseeb tias lub raj teeb ua haujlwm zoo, tab sis nws tseem khaws cov electrodes los ntawm kev puas tsuaj los ntawm kev hloov pauv ntawm voltage. Qhov no yog qhov tseem ceeb heev rau kev ua kom lub teeb raj ntawm cov duab zoo thiab ua rau nws ntev ntev, tshwj xeeb tshaj yog nyob rau hauv cov chaw uas cuam tshuam hluav taws xob tuaj yeem tshwm sim. Cov qauv tsim ntawm lub khob iav kuj tseem tuaj yeem hloov pauv, thiab cov ntaub ntawv uas nyuaj rau kev tawg tuaj yeem siv los ua thaj chaw nrog ntau ntawm kev nyab xeeb ntawm ko taw.
Tsis tas li, ntau ntawm cov raj tshiab raj teeb tau ua rau cov yam ntxwv zoo li lub peev xwm los dim thiab ua haujlwm nrog tshuab ntse. Qhov no cia cov neeg siv hloov theem ntawm ci lossis tswj lub teeb pom kev zoo ntawm afar, uas ua rau lub teeb pom kev yooj yim thiab yoog tau. Cov tswv yim tshiab no qhia tias yuav hloov pauv li cas, nco ntsoov tias lawv nyob kom paub meej thiab muaj peev xwm ua tau raws li ntau qhov chaw niaj hnub.
 

Ntau hom ntawmTeeb Tsoob

Muaj ntau hom teeb txawb, thiab txhua tus yog tsim rau lub hom phiaj sib txawv thiab teeb tsa. Vim tias lawv hloov tau yooj yim, lawv tuaj yeem siv tau rau hauv ntau qhov chaw, los ntawm cov chaw ua haujlwm.

Teeb uas los ntawm cov hlab

Tau ntau xyoo, cov raj raj fluorescent teeb tau ua txoj hauv kev zoo rau kev taws chav. Cov neeg nyiam lawv vim tias lawv muab lub teeb dawb ci thaum siv hluav taws xob tsawg dua li incandescent qij. Cov teeb pom feem ntau yog nyob rau hauv ib tug xov tooj ntawm cov sib txawv thiab xim kub, yog li lawv tuaj yeem siv tau rau ntau qhov chaw, suav nrog cov chav kawm, chaw haujlwm, thiab cov khw muag khoom, chaw haujlwm.
