Incandescent vs Fluorescent

Incandescent thiab fluorescent yog ob hom teeb pom kev zoo, uas yog siv nyob rau hauv lub neej niaj hnub. Incandescent qij thiab fluorescent qhov muag teev yog siv nyob rau hauv ib tug ntau yam ntawm daim ntaub ntawv sib txawv ntawm lub tsev thiab chaw ua hauj lwm teeb pom kev zoo mus rau loj scale factories. Cov tswv yim ntawm cov qij taws thiab cov qij fluorescent ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm xws li kev siv hluav taws xob, kev lag luam ntsuab thiab lwm yam kev siv hluav taws xob. Nyob rau hauv tsab xov xwm no, peb yuav tham txog dab tsi yog qhov muag teeb thiab fluorescent qhov muag teev, lawv cov ntawv thov, qhov zoo sib xws ntawm ob qho no, yuav ua li cas cov qij incandescent thiab fluorescent qhov muag teev yog tsim, thiab thaum kawg qhov sib txawv ntawm cov qhov muag teev incandescent thiab cov qij fluorescent.

Lub teeb taws teeb

Ib lub qhov muag tsis pom kev yog hom teeb pom kev zoo heev, uas tau siv ntau mus txog qhov kev tsim kho tsis ntev los no. Muaj ob peb qhov tseem ceeb ntawm lub teeb incandescent. Qhov tseem ceeb yog lub filament. Lub filament muaj peev xwm dhau ib qho hluav taws xob tam sim no los ntawm nws thaum muaj qhov sib txawv ntawm qhov hluav taws xob siv rau cov terminals ntawm cov filament. Cov filament yog ib puag ncig los ntawm cov roj inert xws li helium uas khaws cia hauv lub hnab ntawv pob tshab ntawm iav.

Lub hauv paus ntsiab lus tom qab lub teeb ci yog qhov ci ntsa iab ntawm cov hlau thaum tam sim no dhau los ntawm cov hlau. Lub filament yog ib tug ntev heev thiab nyias hlau hlau uas yog ua los ntawm tungsten. Xws li ib tug nyias hlau muaj ib tug loj kuj ntawm cov terminals. Xa ib qho tam sim no los ntawm cov filament no ua rau muaj cua sov ntau heev. Lub filament yog ib puag ncig los ntawm cov roj inert, kom tiv thaiv kom tsis txhob muaj cov pa oxygen lossis lwm cov pa roj vim qhov kub thiab txias. Qhov kub ntawm ib lub filament tuaj yeem ncav cuag li 3500 K yam tsis muaj melting. Tungsten qij feem ntau tsis tshua muaj txiaj ntsig dua li lwm hom teeb pom kev zoo.

Fluorescent Noob

Lub teeb fluorescent yog ib qho khoom siv uas siv hluav taws xob ua kom zoo siab thiab tom qab ntawd de-excite mercury vapor. Lub teeb florescent tseem hu ua lub raj fluorescent. Lub de - excitation ntawm mercury vapor, uas zoo siab los ntawm hluav taws xob, ua rau ultraviolet tsis. Cov nthwv dej ultraviolet no ua rau cov txheej txheem fluorescence rau fluoresce. Cov nyhuv fluorescence no ua rau pom lub teeb pom kev.

Lub teeb fluorescent yog qhov ua tau zoo dua hauv kev hloov hluav taws xob rau hauv lub teeb dua li lub teeb incandescent. Lub teeb fluorescent kuj tuaj nyob rau hauv daim ntawv compact uas yog hu ua lub compact fluorescent teeb los yog ntau lub npe hu ua CFL.

Cov qhov muag tsis pom kev tsim lub teeb ncaj qha los ntawm cov cua sov ntawm cov khoom siv thaum lub teeb fluorescent ua rau lub teeb nruab nrab los ntawm cov khoom siv fluorescent
