Puas yuav tag nrho cov diodes emit teeb?

Basic txhais thiab kev faib tawm ntawm diodes
Lub diode, raws li lub npe qhia, hais txog ib qho khoom siv hluav taws xob nrog ob lub electrodes (zoo thiab tsis zoo). Nws cov qauv tseem ceeb yog raws li PN kev sib tshuam, uas yog qhov sib txuas ntawm P-hom semiconductor thiab N-hom semiconductor. Raws li cov khoom sib txawv, cov qauv, kev ua haujlwm, thiab daim ntawv thov, diodes tuaj yeem muab faib ua ntau hom, suav nrog tab sis tsis txwv rau:
Rectifying diode: feem ntau yog siv los hloov alternating tam sim no rau hauv ncaj qha tam sim no, nws yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob hluav taws xob.
Ntes diode: Hauv xov tooj cua tau txais circuits, nws yog siv los rho tawm cov ntaub ntawv nyoos los ntawm cov teeb liab modulated.
Switching diode: Nyob rau hauv digital circuits, nws yog siv los ua ib tug high-speed switching caij los tswj lub on / off ntawm Circuit Court.
Zener diode: Muab cov khoom tso tawm ruaj khov los ntawm cov yam ntxwv rov qab, siv rau hauv cov khoom siv hluav taws xob ruaj khov.
Lub teeb emitting diodes (LEDs): hloov hluav taws xob rau hauv lub teeb lub zog thiab tau siv dav hauv thaj chaw xws li teeb pom kev zoo, zaub, thiab kev taw qhia.
Cov yam ntxwv tshwj xeeb ntawm Lub Teeb Emitting Diodes (LEDs)
Ntawm cov pawg saum toj no, lub teeb-emitting diodes (LEDs) sawv tawm vim lawv qhov tshwj xeeb emission yam ntxwv. Cov qauv tseem ceeb ntawm LED zoo ib yam li cov diodes zoo tib yam, tab sis qhov tseem ceeb nyob hauv kev xaiv cov khoom siv thiab ntim tshuab. LEDs feem ntau siv cov khoom siv semiconductor uas tuaj yeem hloov hluav taws xob ncaj qha rau hauv lub teeb lub zog, xws li cov khoom sib txuas ntawm silicon thiab germanium. Thaum lub LED yog pem hauv ntej biased, electrons raug txhaj los ntawm N cheeb tsam mus rau hauv cheeb tsam P, recombine nrog qhov nyob rau hauv P cheeb tsam, thiab tso tawm lub zog. Lub zog no yog radiated tawm hauv daim ntawv ntawm photons, uas ua rau brightness.
Txawm li cas los xij, nws tsim nyog sau cia tias tsis yog txhua lub LEDs tawm teeb pom kev zoo. Raws li cov ntaub ntawv sib txawv ntawm cov khoom siv hluav taws xob, LEDs tuaj yeem tso lub teeb sib txawv ntawm cov wavelengths los ntawm infrared mus rau ultraviolet, suav nrog txawm tias pom tsis pom microwave thiab xov tooj cua zaus hluav taws xob. Tab sis hauv qhov kev sib tham no, peb feem ntau tsom rau LEDs uas tuaj yeem pom lub teeb pom kev.
Diversity thiab Function ntawm Non Light Emitting Diodes
Piv rau LEDs, lwm hom diodes tsis muaj luminescent zog. Lawv lub luag haujlwm tseem ceeb suav nrog kev tswj xyuas tam sim no, kev tswj hluav taws xob, kev kuaj pom lub teeb liab, thiab lwm yam. Piv txwv li:
Rectifying diode: Los ntawm nws cov unidirectional conductivity, tsuas yog ib thiab ib nrab nthwv dej ntawm alternating tam sim no raug tso cai kom dhau mus, yog li ua tiav qhov hloov dua siab tshiab los ntawm alternating tam sim no mus rau tam sim no.
Ntes diode: Hauv kev sib txuas lus wireless, nws yog siv los rho tawm cov teeb liab qis qis los ntawm cov neeg nqa khoom siab thiab ua tiav cov teeb liab demodulation.
Switching diode: Hauv digital circuits, raws li kev hloov pauv ceev, nws yog siv los tswj lub hauv / tawm lub xeev ntawm lub voj voog, ua tiav kev ua haujlwm thiab cov ntaub ntawv xa mus.
Zener diode: Siv nws cov yam ntxwv thim rov qab, nws muab cov zis hluav taws xob ruaj khov nyob rau hauv qhov tshwj xeeb voltage ntau, tiv thaiv Circuit Court los ntawm qhov hloov pauv voltage.
Kev xaiv thiab siv cov diodes
Hauv kev siv tswv yim, kev xaiv ntawm hom diode nyob ntawm qhov kev thov tshwj xeeb scenario thiab cov cai. Piv txwv li, hauv thaj chaw teeb pom kev zoo thiab cov zaub, LEDs tau txais txiaj ntsig zoo vim lawv cov kev ua haujlwm siab, kev siv hluav taws xob zoo, thiab kev phooj ywg ib puag ncig; Nyob rau hauv lub tshav pob hluav taws xob hluav taws xob, rectifying diodes thiab voltage stabilizing diodes yog cov khoom tseem ceeb rau kev ua tiav lub zog hloov dua siab tshiab thiab voltage stability; Hauv kev sib txuas lus thiab kev tsim cov teeb liab, kev kuaj pom diodes thiab hloov diodes ua lub luag haujlwm tsis tuaj yeem hloov pauv.
Tsis tas li ntawd, nrog rau txoj kev loj hlob ntawm technology, daim ntawv thov teb ntawm diodes yog tas li nthuav. Piv txwv li, nyob rau hauv lub tshav pob ntawm optoelectronics, cov cuab yeej tshiab xws li diode raws li lasers thiab photodetectors tau tshwm sim tas li, muab kev txhawb zog rau cov teb xws li kev sib txuas lus kho qhov muag, kho qhov muag, thiab kho qhov muag pom.
