Qhov twg zoo dua, LED lossis laser diode?

Txoj haujlwm ua haujlwm thiab cov khoom siv kho qhov muag
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm LED yog ua raws li kev sib txuas ntawm electrons thiab qhov. Thaum tam sim no dhau los ntawm PN kev sib tshuam, electrons txav los ntawm N-hom cheeb tsam mus rau thaj tsam P-hom, ua ke nrog lub qhov, thiab tso tawm lub zog, uas yog tawm hauv daim ntawv ntawm photons, tsim lub teeb pom kev. Lub teeb tsim los ntawm LED yog lub teeb tsis sib xws, nrog rau ib qho xim tab sis tsis zoo rau kev taw qhia, thiab lub teeb kuj tawg.
Lub laser diode ntxiv qhov kho qhov muag resonant kab noj hniav nyob rau hauv lub hauv paus no, uas amplifies lub teeb ntawm tej wavelengths thiab yuam kom lawv emit coherently nyob rau hauv ib qho kev taw qhia, tsim ib tug laser beam. Cov txheej txheem no yuav tsum muaj tus qauv tsim ntawm tus lej particle inversion lub xeev hauv lub laser diode thiab lub ntsej muag daim iav kom ua tiav cov txheej txheem hluav taws xob txhawb nqa. Yog li ntawd, lub teeb generated los ntawm laser diodes muaj siab directionality thiab coherence, ib tug nqaim zaus ntau yam (zoo monochromaticity), thiab muaj peev xwm yuav concentrated mus rau hauv me me kab teeb uas propagate nyob ntev.
Kev siv hluav taws xob thiab thaj chaw siv
LED muaj kev ua haujlwm siab luminous, tuaj yeem ncav cuag qib siab, thiab siv hluav taws xob tsawg, ua rau nws tsim nyog rau cov teeb pom kev zoo thiab lwm yam kev siv uas xav tau kev pab dav dav. Piv txwv li, LEDs tau siv dav hauv cov teb xws li cov teeb qhia, cov teeb pom kev hauv qab, thiab cov teeb pom kev dav dav. Nws qhov kev siv hluav taws xob tsawg thiab lub neej ntev ua rau LED yog lub teeb pom kev zoo hauv ntau yam khoom siv hluav taws xob.
Hauv qhov sib piv, laser diodes muaj lub zog tso zis ntau dua, feem ntau yog li ntawm kaum tawm milliwatts mus rau ob peb watts, lossis ntau dua, ua tau raws li qhov xav tau ntawm lub zog siab ntawm qee yam cuab yeej precision. Lub siab brightness, zoo directionality, thiab muaj zog monochromaticity ntawm laser diodes ua rau lawv lug siv nyob rau hauv kev lag luam xws li fiber optic kev sib txuas lus, laser printers, cov cuab yeej kho mob, thiab kev tshawb fawb cov cuab yeej. Piv txwv li, nyob rau hauv cov teb xws li laser npav, laser txiav, thiab laser therapy, laser diodes tau pom zoo unparalleled zoo vim lawv siab precision thiab siab zog ceev.
Nqi thiab lifespan
Los ntawm kev xav txog tus nqi, cov nqi tsim khoom ntawm LEDs yog qhov tsawg, nrog lub neej ua haujlwm ntev thiab cov nqi kho mob tsawg. Qhov no yog vim cov qauv yooj yim, yooj yim ntawm kev tsim khoom, thiab kev tsim khoom loj ntawm LED. Yog li ntawd, LED muaj tus nqi tseem ceeb thiab siv dav hauv cov khoom siv hluav taws xob thiab teeb pom kev lag luam.
Tus nqi tsim khoom ntawm laser diodes feem ntau yog siab dua, uas yog ze ze rau lawv cov txheej txheem ua haujlwm nyuaj thiab cov txheej txheem raug tsim. Nyob rau tib lub sijhawm, vim nws cov kev ua haujlwm tshwj xeeb, kev ntsuas qhov kub thiab txias yuav tsum tau ua kom muaj kev ruaj ntseg, yog li tag nrho cov kev ntseeg siab thiab kev ua neej yuav raug cuam tshuam rau qee qhov. Txawm li cas los xij, daim ntawv thov tus nqi ntawm laser diodes hauv cov teb tshwj xeeb tsis tuaj yeem hloov pauv.
