Sib tham txog cov nyhuv ntawm hluav taws xob muaj hluav taws xob ntawm LED zaub
Qhov hluav taws xob tau zoo yog qhov ua tau zoo ib yam ntawm voltage, uas yog tsim los ntawm kev sib cuag thiab kev sib cais ntawm ntau hom tshuaj. Qhov no yog lub tshuab hluav taws xob uas paub zoo tshaj plaws, vim hais tias qhov hluav taws xob tsis yog loj, yog li peb feem ntau tsis muaj qhov zoo li hluav taws xob. Tab sis rau cov lag luam tsim hluav taws xob ua lag luam, qhov cuam tshuam loj heev. Dab tsi yog qhov hluav taws xob muaj hluav taws xob muaj nyob rau ntawm LED teeb pom kev zoo?
Vim hais tias LED loj loj hauv cov txheej txheem ntau lawm mas yog kev sib txuas lus ncaj nraim thiab tsis ncaj nraim ntawm tib neeg lub cev thiab lwm yam khoom los tsim hluav taws xob. Yog li ntawd, raws li cov yam ntxwv ntawm txoj kev lag luam, peb tuaj yeem ua tau qee yam kev tiv thaiv zoo li qub.
Thaum cov khoom siv hluav taws xob txuas rau ib leeg los sis ntsaws rau hauv Circuit Court, kev puas tsuaj rau cov cuab yeej no yuav tshwm sim vim muaj hluav taws xob zoo li qub txawm tias tsis muaj hwj chim siv. LEDs yog semiconductor khoom uas tuaj yeem ua rau cov khoom puas tsuaj yog tias qhov voltage ntawm ob pins los yog ntau dua ntawm cov LEDs tshaj qhov lub zog rhuav tshem ntawm kev tiv thaiv kev tawm. Lub thev qhov oxide txheej, qhov ntau dua qhov lub zog ntawm cov LED thiab cov tsav tsheb mus rau hluav taws xob zoo li qub. Piv txwv li, lub kav tsuag tsis puv, qhov zoo ntawm lub kwj ntawm nws tus kheej yog teeb meem, thiab lwm yam, thiab txoj kev xoob loj yuav tshwm sim, ua rau kev puas tsuaj loj! Lwm hom tsis ua hauj lwm yog tshwm sim los ntawm qhov ntsuas kub ntawm qhov teeb meem tshaj qhov nruab nrab ntawm qhov nruab nrab ntawm semiconductor silicon (1415 ° C).
Electrostatic pulse energy yuav ua kom muaj kev kub ntxhov, thiaj li muaj kev sib txuas ntawm lub teeb thiab lub kos. Qhov no tsis tuaj yeem tshwm sim txawm tias qhov voltage qis dua qhov sib tsoo ntawm qhov nruab nrab. Ib qho piv txwv yog tias LED yog ib qho diode uas muaj pn hlav, thiab kev sib tshuam ntawm cov emitter thiab lub hauv paus ua rau poob ntse hauv kev nce qib tam sim no. Tom qab lub teeb nws tus kheej los yog tus ntiv taw nyob hauv tus neeg tsav tsheb muaj kev cuam tshuam los ntawm kev siv hluav taws xob, kev ua haujlwm tsis zoo yuav tshwm sim sai li sai tau. Cov khoom uas feem raug mob feem ntau yog tshwm sim thaum siv, yog li lub neej ntawm LED qhov tshuaj ntsuam loj yog cuam tshuam. Nws yog kev tuag.
