Vim tias cov qhov muag tsis pom kev tsis ua haujlwm zoo, kev tshawb fawb txog hluav taws xob txuas ntxiv nthuav dav. Nyob rau hauv lub xyoo pua 19th, Heinrich Geissler (glassblower) thiab Julius Plücker (tus kws kho mob) pom tias nws muaj peev xwm tsim lub teeb los ntawm kev tshem tawm yuav luag tag nrho cov huab cua tawm ntawm lub iav raj ntev thiab cia cov hluav taws xob tam sim no hla nws. Qhov kev tsim kho no tau dhau los ua lub npe hu ua Geissler raj (hom lub teeb tawm), tab sis nws tsis tau muaj koob meej mus txog thaum xyoo pua 20th, thaum cov kws tshawb fawb nrhiav txoj hauv kev los txhim kho nws cov teeb pom kev zoo. Cov teeb hluav taws xob tau dhau los ua lub hauv paus ntawm ntau lub teeb pom kev zoo niaj hnub xws li cov teeb hluav taws xob tsawg, cov raj fluorescent, thiab cov teeb neon.
Nyob rau xyoo 1890, Thomas Edison thiab Nikola Tesla tau sim cov teeb fluorescent, tab sis nws yog Peter Cooper Hewitt uas tau ua tiav thaum xyoo 1900s. Nws ua lub teeb xiav-ntsuab los ntawm kev cia cov hluav taws xob tam sim no dhau los ntawm mercury vapor thiab ua ke nrog lub ballast (ib yam khoom uas txuas nrog lub raj uas tswj cov dej ntws tam sim no). Txawm hais tias Hewitt's fluorescent teeb tau zoo dua li qhov muag teeb, lawv tsis muaj ntau yam vim lawv cov xim.
Cov kws tshawb fawb nyob sab Europe tau pib tshawb nrhiav cov raj neon uas npog nrog phosphorus thaum xyoo 1920 thiab thaum ntxov 1930s. Cov kev tshawb pom no tau pib kawm ntxiv, thiab los ntawm nruab nrab thiab lig xyoo 1930s, cov teeb pom kev zoo fluorescent no tau tshwm sim ntawm New York World's Fair. Tom qab ntawd peb dhia mus rau ib ncig ntawm 1976, yug ntawm compact fluorescent light (CFL) signaled ib kaj kaj ntug tshiab nyob rau hauv lub teeb pom kev lag luam. Txawm li cas los xij, thawj CFLs yog pricey, loj, tsis haum zoo nrog fixtures, muaj teeb pom kev zoo tsis tshua muaj thiab tsis zoo nyob rau hauv kev ua tau zoo. Vim tias qhov kev poob qis no, thev naus laus zis tau tsim kho ntxiv, thiab txij li xyoo 1990s, kev txhim kho loj heev tau pom nyob rau hauv tus nqi, kev ua tau zoo, thiab lub neej ntev.
Dab tsi tshwm sim tom qab fluorescents?
Tom qab xyoo ntawm kev tshawb fawb thiab kev loj hlob, lub ntiaj teb no tau qhia rau ib qho ntawm kev hloov kho teeb pom kev zoo tshaj plaws nyob rau tam sim no, lub teeb-emitting diodes (LEDs). LEDs yog hom teeb pom kev zoo hauv lub xeev uas siv cov khoom siv hluav taws xob los hloov lub zog rau hauv lub teeb thiab tawm mus rau hauv ib qho kev taw qhia tshwj xeeb, txo qhov xav tau ntawm diffusers thiab reflectors, uas xaus rau lub teeb teeb. LEDs yog qhov ci ntsa iab tshaj plaws, muaj zog tshaj plaws, lub teeb pom kev ntev tshaj plaws uas koj tuaj yeem tau txais tam sim no, thiab nws yog qhov zoo tshaj plaws.
