Kev siv dav ntawm diode lub teeb pom kev zoo ua rau koj xav tsis thoob: yuav siv lub thev naus laus zis no kom txuag hluav taws xob zoo yav tom ntej lossis cov nqi siab ntawm cov khoom yuav tsis cia lawv siv dav?
Cov teeb cig LED tau txiav txim siab nyob hauv qhov chaw teeb pom kev zoo thev naus laus zis, muab cov neeg siv nrog cov khoom siv hluav taws xob thoob ntiaj teb nrog kev siv hluav taws xob tsawg thiab kev ua haujlwm yuav luag tag. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm LED yog ua raws li kev muaj peev xwm ntawm qee hom kev sib txawv ntawm cov tshuab hluav taws xob kom tso duab photons thaum hluav taws xob hluav taws xob dhau los ntawm pn hlws ris. Qhov qauv tseem ceeb no muaj qhov sib txawv ntawm LED los ntawm qhov ntsiab lus tsis sib haum, uas tawm lub teeb pom kev tsuas yog sov siab thiab muaj peev txheej tsawg.
Cov lus nug hais txog kev siv loj ntawm LEDs rau qee qhov kev daws teeb meem ntawm lub zog hluav taws xob tsis tuaj yeem teb tau yam tsis muaj tseeb. Ntawm ib sab, yuav luag ib nrab ntawm hluav taws xob hauv tsev neeg thiab kev tswj hwm tau siv rau kev siv teeb pom kev zoo, yog li kaum tawm hauv qhov ntim no tuaj yeem pab txhawb kev ua haujlwm ntawm kev txuag hluav taws xob. Ntawm qhov tod tes, kev tsim cov LEDs yog ib qho nyuaj thiab kev siv khoom siv dag zog ua haujlwm.
Qhov zoo ntawm LEDs hla lub teeb cig lam lug
Tus qauv tsim ntawm cov LED pom qhov kev pab lub neej ntev ntawm cov khoom siv hluav taws xob. Qhov tsis muaj ntawm ib qho khoom uas ua kom sov los ntawm kev sib tsoo ntawm hluav taws xob hauv qhov pom kev tshem tawm tshem tawm qhov poob ntawm lub zog rau kev tsim kom muaj cua sov. Tsis tas li, LEDs muaj kev cog lus heev, uas tso cai rau ntau pua emitters tso rau ntawm ib qho vaj huam sib luag, thiaj li muab lub teeb muaj zog zoo. Cov LED hluav taws xob tuaj yeem ua haujlwm nyob rau txhua qhov xwm txheej huab cua, uas tsis tuaj yeem hais txog lub teeb taws uas tsis ua haujlwm thiab fluorescent teeb ci. Nyob rau hauv teeb meem ntawm cov teeb pom kev zoo nkauj ntawm cov teeb pom kev zoo, LEDs kuj muaj qhov txiaj ntsig zoo: los ntawm kev hloov tus nqi ntawm qhov muab cov voltage thiab qhov tam sim no, koj tuaj yeem hloov kho lub zog thiab xim ntawm hluav taws xob, uas yog qhov tseem ceeb rau kev tshaj tawm kev tshaj tawm.
Qhov tsis zoo ntawm cov teeb pom kev ntawm LED
Ntxiv nrog rau qhov kev cuam tshuam tseem ceeb, uas yog tus nqi siab ntawm cov teeb txawb LED, lawv tau qis dua cov teeb pom kev zoo nyob rau qee yam tsis pub dhau. Piv txwv, emission spectrum ntawm LEDs yog qhov pom nqaim. Lub teeb yog tsim nrog qhov siab ntawm oscillation, yog li lub teeb ci nws tus kheej pom tau los ntawm qhov chaw nyob deb, tab sis illuminates tsuas yog thaj tsam xwb. Kuj, txuag hluav taws xob kom zoo yog qhov tseem ceeb rau LED teeb, txij li tus neeg xyuas pib nws tus kheej hauv qhov kub kub qeeb thiab poob nws zoo.
Cov lus nug ntawm kev siv loj
LEDs, hauv txoj ntsiab cai, tuaj yeem hloov cov teeb pom kev ib txwm, muab cov kev txuag nyiaj tseem ceeb hauv kev siv lub zog. Lawv cov nqi siab tsis yog qhov khoom plig tseem ceeb. Qhov ntau lub sijhawm ua haujlwm nyob rau kev ua haujlwm ntau dua ua rau cov nqi ntawm cov teeb tsa sib npaug sib npaug rau cov khoom sib xws. Tib qho chaw khuam siab yog qhov tsis muaj ntau lawm thiab tsis muaj npe nrov ntawm cov pej xeem, tab sis cov teeb meem no tau daws dhau sijhawm.
