YRectifier Diode vs LED
Diode yog cov khoom siv hluav taws xob semiconductor, uas muaj ob txheej txheej semiconductor. Rectifier diode thiab LED (Lub Teeb Emitting Diode) yog ob hom diodes siv ntau hom kev siv. LED yog ib hom tshwj xeeb ntawm diode uas muaj peev xwm emit lub teeb, uas tsis tuaj yeem pom nyob rau hauv ib txwm diodes. Cov neeg tsim qauv xaiv lawv raws li qhov yuav tsum tau ua ntawm daim ntawv thov
Rectifier Diode
Diode yog cov khoom siv hluav taws xob yooj yim tshaj plaws thiab nws muaj ob txheej txheej semiconductor (ib P-hom thiab ib hom N-hom) txuas rau ib leeg. Yog li ntawd, diode yog PN kev sib tshuam. Diode muaj ob lub terminals hu ua anode (p-hom txheej) thiab cathode (n-hom txheej).
Diode tso cai rau tam sim no ntws los ntawm nws tsuas yog hauv ib qho kev coj, uas yog los ntawm anode mus rau cathode. Qhov kev taw qhia ntawm tam sim no yog cim rau ntawm nws lub cim ua tus xub taub hau. Txij li thaum diode txwv qhov tam sim no kom ntws tsuas yog ib qho kev taw qhia, nws tuaj yeem siv los ua rectifier. Tag nrho tus choj rectifier Circuit Court, uas yog ua los ntawm plaub lub diodes tuaj yeem kho qhov hloov tam sim no (AC) mus rau qhov ncaj qha tam sim no (DC).
Lub diode pib ua tus neeg xyuas pib thaum lub zog me me tau siv rau hauv kev coj ntawm anode rau cathode. Qhov kev poob qis no (paub tias yog qhov kev poob qis rau pem hauv ntej) yog ib txwm muaj thaum muaj qhov tam sim no tshwm sim. Qhov voltage no feem ntau yog 0.7V rau ib txwm silicon diodes.
LED (Lub teeb Emitting Diode)
LED kuj yog hom diode uas tuaj yeem tawm lub teeb thaum ua haujlwm. Txij li thaum diode muaj P-hom thiab N-hom semiconductor txheej, ob qho tib si 'electrons' thiab 'qhov' (cov neeg nqa khoom zoo tam sim no) koom nrog hauv kev coj ua. Yog li ntawd, cov txheej txheem 'recombination' (ib qho tsis zoo electrons koom nrog lub qhov zoo) tshwm sim, tso qee lub zog. LED yog tsim nyob rau hauv ib txoj kev uas, cov energies raug tso tawm nyob rau hauv cov nqe lus ntawm photons (lub teeb hais) ntawm nyiam xim.
Yog li ntawd LED yog lub teeb pom kev zoo, thiab nws muaj ntau yam zoo xws li kev siv hluav taws xob, kev ua haujlwm ntev, me me thiab lwm yam. Tam sim no ib puag ncig tus phooj ywg LED teeb pom kev zoo tau tsim thiab lawv kuj tau siv rau hauv cov khoom niaj hnub no.
Dab tsi yog qhov txawv ntawm Rectifier Diode thiab LED
1. LED emits lub teeb thaum ua, whereas rectifier diode tsis emit.
2. LEDs feem ntau yog siv los ua lub teeb ci, thiab cov diodes rectifier yog siv los kho cov ntawv thov.
3. Cov khoom siv hauv rectifier diodes thiab LED's muaj cov khoom sib txawv.
