"LED hlws ris kub" tsis yog li paub rau cov neeg feem coob, tab sis txawm rau cov neeg hauv kev lag luam LED! Tam sim no cia peb piav qhia meej. Thaum lubLED ua haujlwm, cov xwm txheej hauv qab no tuaj yeem txhawb qhov kev sib tshuam ntawm qhov kub thiab txias kom nce hauv qhov sib txawv.

1, Nws tau raug pov thawj los ntawm ntau yam kev coj ua uas qhov kev txwv ntawm lub teeb pom kev zoo yog qhov laj thawj tseem ceeb rau qhov nce ntawm LED qhov kub thiab txias. Tam sim no, kev loj hlob ntawm cov khoom siv thiab cov cuab yeej tsim khoom siv tau tuaj yeem hloov pauv feem ntau ntawm cov tswv yim hluav taws xob ntawm kev coj mus rau lub teeb hluav taws xob hluav taws xob. Txawm li cas los xij, vim qhov loj dua refractive index ntawmLED nticov ntaub ntawv piv nrog cov nruab nrab ib puag ncig, feem ntau photons (> 90%) tsim nyob rau hauv lub nti tsis tuaj yeem ua rau lub ntsej muag tsis zoo, thiab tag nrho cov kev xav tau tshwm sim ntawm qhov cuam tshuam ntawm nti thiab nruab nrab, Nws rov qab mus rau sab hauv ntawm lub nti thiab thaum kawg absorbed. los ntawm cov khoom siv nti lossis substrate los ntawm ntau qhov kev xav hauv sab hauv, thiab dhau los ua cua sov hauv daim ntawv ntawm cov hlua khi, uas txhawb nqa qhov kub ntawm qhov sib txuas.

2, Vim hais tias lub pn hlws ris tsis tuaj yeem ua tau zoo heev, qhov kev txhaj tshuaj ntawm cov khoom yuav tsis ncav cuag 100%, uas yog, thaum lub LED ua haujlwm, ntxiv rau kev txhaj tshuaj (qhov) rau hauv n cheeb tsam hauv cheeb tsam P, n thaj chaw kuj tseem yuav txhaj cov nqi hluav taws xob (electron) rau hauv thaj tsam P. Feem ntau, tus nqi txhaj tshuaj ntawm hom tom kawg yuav tsis tsim cov nyhuv optoelectric, tab sis yuav raug siv rau hauv daim ntawv ntawm cov cua sov. Txawm tias qhov tseem ceeb ntawm cov nqi txhaj tshuaj yuav tsis yog tag nrho cov teeb pom kev zoo, thiab qee qhov yuav dhau los ua cua sov thaum ua ke nrog impurities lossis tsis xws luag hauv cheeb tsam junction.

3 、 Cov qauv hluav taws xob tsis zoo ntawm lub caij, cov khoom siv ntawm lub qhov rais txheej substrate los yog hlws ris cheeb tsam thiab cov conductive silver kua nplaum tag nrho muaj ib tug tej yam kuj nqi. Cov kev tawm tsam no yog stacked nrog ib leeg los tsim cov kev tawm tsam ntawm covLED khoom. Thaum cov tam sim no ntws los ntawm pn hlws ris, nws tseem yuav ntws los ntawm cov resistors, uas ua rau Joule kub, uas ua rau qhov nce ntawm nti kub los yog hlws ris kub.

Tau kawg, nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, qhov laj thawj tseem ceeb vim li cas peb tsis tuaj yeem nkag siab txog cov xwm txheej saum toj no ib qho los ntawm ib qho yog tias peb tsis tuaj yeem nkag siab lawv ib qho los ntawm ib qho yav tom ntej. Tau kawg, peb tsis tuaj yeem nkag siab lawv ib qho los ntawm ib qho nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis!
