Teeb pom kev zoo thiab teeb pom kev zoo

Ib txoj hauv kev ntawm lub teeb tsim yog thermal tawg, thiab lwm qhov zoo siab los tawm lub teeb.

Incandescent teeb, tungsten halogen teeb, thiab lwm yam.

Peb cov teeb incandescent emit kub los ntawm tshav kub hluav taws xob. Lub zog hluav taws xob yog siv los ua kom sov lub filament mus rau lub xeev incandescent kom emit lub teeb. Tsis tas li ntawd, yuav muaj ntau qhov hluav taws xob infrared thiab qee qhov hluav taws xob sab nraud. Ib feem me me ntawm nws tau hloov mus rau hauv lub teeb lub zog, thiab feem ntau nws hloov mus rau hauv lub zog hluav taws xob, yog li qhov ua tau zoo ntawm cov teeb ci incandescent yog qhov tsawg.

Tungsten hlau yog cov khoom siv filament feem ntau rau peb. Edison kuj tau dhau los ntawm kev xeem suav tsis txheeb thiab thaum kawg xaiv tungsten hlau ua cov khoom siv rau cov teeb ci. Lub luminous efficiency ntawm tungsten filament nce nrog qhov kub thiab txias ntawm tungsten filament, uas txhais tau hais tias qhov kub ntawm cov tungsten filament ntau dua, qhov siab dua qhov kev ua tau zoo ntawm cov filament, thiab ntau lub zog hluav taws xob hloov mus rau lub teeb lub zog.

Lub melting point ntawm tungsten hlau yog 3683k. Txawm hais tias qhov kev ruaj ntseg zoo, thaum qhov kub ntawm tungsten hlau nce ntxiv txhawm rau txhim kho lub teeb pom kev zoo, qhov evaporation ntawm tungsten hlau yuav nrawm dua, uas yuav ua rau nws lub neej luv. Halogen cov ntsiab lus raug tshem tawm, txo qhov poob ntawm filament, ua kom nws lub neej ua haujlwm ntev, thiab txhim kho lub teeb pom kev zoo tib lub sijhawm. Incandescent qhov muag teev tuaj nyob rau hauv ntau yam duab. Cov khoom siv feem ntau yog iav, thiab nws qhov kub tsis kam yog feem ntau suav hais tias yog. Lub teeb xim ntawm cov teeb ci incandescent feem ntau yog nyob ntawm kev siv cov xim iav zoo nkauj, lossis cov qauv ntawm cov xim ntawm lub plhaub phab ntsa. Cov tuav lub teeb feem ntau yog hom bayonet lossis hom ntsia hlau.

Lub teeb incandescent tau pib tshem tawm vim lawv lub teeb pom kev tsis zoo thiab kev siv lub zog siab. Txawm li cas los xij, vim qhov tshwj xeeb ntawm cov xim ntawm cov teeb pom kev zoo, lawv tseem tuaj yeem siv rau hauv qee qhov teeb pom kev zoo nkauj lossis zaj duab xis thiab TV teeb pom kev zoo.

Tungsten Halogen Teeb

Xav txog tias cov tungsten hlau yuav nrawm rau kev laus thaum qhov kub thiab txias los txhim kho lub teeb pom kev zoo. Txij li thaum lub tungsten filament yuav evaporate, yog hais tias lub hauv paus ntsiab lus ntawm tungsten halogen voj voog yuav siv tau nyob rau hauv lub teeb, lub teeb efficiency yuav zoo dua thiab lub neej ntawm cov filament yuav ncua. Lub hauv paus ntsiab lus ntawm tungsten halogen ncig yog rov qab cov tungsten evaporated mus rau tungsten hlau thiab ntxuav lub qhov muag teev nyob rau tib lub sijhawm. Tungsten-halogen teeb feem ntau muaj qhov kub siab dua li cov iav zoo tib yam, yog li lawv feem ntau yog ua los ntawm quartz. Tungsten-halogen teeb feem ntau yog elongated nyob rau hauv cov duab. Vim lub teeb xim yam ntxwv ntawm tungsten halogen teeb, kev ua haujlwm siab thiab kev ua haujlwm ntev, tseem muaj qee qhov kev siv hauv cov yeeb yaj kiab thiab TV teeb pom kev zoo, teeb pom kev lag luam, teeb pom kev ua kis las thiab lwm yam.

Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, qee cov khoom siv hluav taws xob hluav taws xob luminescent tau tsim, xws li graphene Joule thermoluminescence. Lub teeb ultra-thin luminous uas tsim los ntawm cov khoom siv thiab thev naus laus zis no muaj qhov tuab ntawm tsuas yog 0.34 nanometers. Nws kuj tseem siv tau rau kev sib txuas lus kho qhov muag ceev thiab kev sib txuas ntawm qhov muag.

gas paug teeb

Lub teeb tawm roj yog lub teeb hluav taws xob electroluminescent. Feem ntau cov yog glow discharge thiab arc tawm. Peb cov teeb pom kev zoo neon yog ci ntsa iab. Feem ntau cov teeb pom kev zoo siv arc teeb los tsim hluav taws xob. Fluorescent teeb thiab hlau halide teeb yog cov roj tso tawm roj. Tab sis lub teeb tungsten-halogen peb nyuam qhuav tham txog tseem yog lub teeb ci ntsa iab, tsis yog lub teeb hluav taws xob. Txawm hais tias lub npe ntawm tungsten-halogen teeb muaj halogen nyob rau hauv nws, nws tseem emits lub teeb los ntawm cua sov tungsten hlau.

Low-pressure sodium teeb kuj yog ib hom roj tso tawm teeb. Nws muaj kev ua haujlwm siab luminous tab sis qis xim rendering Performance index. Nws yog tsim rau txoj kev teeb pom kev zoo, muaj teeb pom kev zoo, dej nyab teeb pom kev zoo thiab lwm yam.

Cov teeb fluorescent, cov teeb uas feem ntau siv ua ntej thiab qee zaum siv niaj hnub no. Lub hauv paus ntsiab lus luminous ntawm cov teeb fluorescent yog qhov tsis tshua muaj siab mercury vapor discharge, ib feem me me uas hloov mus rau hauv lub teeb pom kev, thiab feem ntau nws hloov mus rau ultraviolet lub teeb thiab lub zog kub. Ntawm lawv, lub teeb ci ultraviolet ntsib cov fluorescent hmoov coated ntawm lub teeb raj thiab ua kom pom lub teeb. Lub teeb ntawm fluorescent teeb feem ntau muaj xim kub dua. Piv nrog rau cov teeb ci incandescent, cov teeb fluorescent muaj lub neej ua haujlwm ntev dua thiab ua haujlwm zoo dua. Lawv feem ntau hu ua lub teeb txuag hluav taws xob yav dhau los.

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub teeb fluorescent yuav tsum tau preheating, yog li yuav tsum muaj ballast, pib ntaus ntawv. Cov ballasts muaj xws li magnetic ballasts thiab hluav taws xob ballasts. Vim nws qhov me me thiab muaj zog tsim qauv, hluav taws xob ballasts tau siv ntau dua.
