Nyob rau hauv xyoo tas los no, LED zaub ntau lawm tshuab tau maj mam matured nyob rau hauv peb lub teb chaws, thiab ntau thiab nrov ntawm daim ntaub ntawv tau dhau los ua ib tug qauv. Txawm li cas los xij, feem ntau ntawm LED cov khoom lag luam tam sim no tsis muaj peev xwm tsim cov khoom zoo li no, uas ua rau muaj kev phom sij rau LED cov khoom lag luam thiab tseem cuam tshuam rau tag nrho lub khw. Cov hluav taws xob zoo li qub yog ib qho ntawm lawv. Yog li, dab tsi yog qhov ua rau hluav taws xob zoo li qub ntawm LED zaub? Dab tsi cuam tshuam qhov hluav taws xob zoo li qub coj mus rau kev tsim cov duab LED?

Ua rau hluav taws xob zoo li qub
Raws li kev xav ntawm microscopic pom, raws li kev xav ntawm atomic physics, qhov teeb meem nyob rau hauv lub xeev ntawm hluav taws xob sib npaug thaum nws yog hluav taws xob nruab nrab, thiab qhov nce thiab poob ntawm cov hluav taws xob tsim los ntawm kev sib cuag ntawm cov khoom sib txawv electrons ua rau cov teeb meem poob hluav taws xob. sib npaug thiab tsim hluav taws xob zoo li qub.
Los ntawm macro taw tes ntawm view, cov laj thawj yog: kev sib txhuam ntawm cov khoom generates tshav kub, uas nkoos electron hloov; kev sib cuag thiab sib cais ntawm cov khoom tsim hluav taws xob hloov pauv; electromagnetic induction ua rau tsis sib npaug ntawm cov nqi ntawm cov khoom; kev sib xyaw ua ke ntawm kev sib txhuam thiab electromagnetic induction.
Electrostatic voltage yog tsim los ntawm kev sib cuag thiab sib cais ntawm ntau hom tshuaj. Cov nyhuv no yog hu ua triboelectricity, thiab qhov voltage generated nyob ntawm seb cov yam ntxwv ntawm cov ntaub ntawv sib tsoo. Vim tias lub vijtsam LED zaub yog feem ntau nyob rau hauv cov txheej txheem tsim khoom tiag tiag, kev sib cuag ncaj qha thiab tsis ncaj ntawm tib neeg lub cev thiab cov khoom muaj feem cuam tshuam tsim hluav taws xob zoo li qub. Yog li ntawd, raws li cov yam ntxwv ntawm kev lag luam, qee qhov kev tiv thaiv electrostatic tiv thaiv tuaj yeem ua tau.

Kev puas tsuaj ntawm hluav taws xob zoo li qub hauv cov txheej txheem tsim khoom ntawm LED zaub
Yog hais tias anti-static yog neglected nyob rau hauv ib tug nam ntawm ntau lawm, nws yuav ua rau cov khoom siv hluav taws xob malfunction los yog ua rau nws puas.
Thaum cov khoom siv semiconductor muab tso rau ib leeg lossis hauv ib lub voj voog, txawm tias lawv tsis tau siv, hluav taws xob zoo li qub yuav ua rau muaj kev puas tsuaj mus tas li rau cov khoom siv no. Raws li peb txhua tus paub, LEDs yog cov khoom lag luam semiconductor. Yog hais tias qhov voltage ntawm ob los yog ntau tus pins ntawm lub LED tshaj lub zog tawg ntawm cov khoom nruab nrab, nws yuav ua rau cov khoom puas. Lub thinner txheej oxide, ntau dua qhov rhiab heev ntawm LEDs thiab tsav ICs rau hluav taws xob zoo li qub. Piv txwv li, qhov tsis muaj solder, qhov zoo ntawm cov solder nws tus kheej, thiab lwm yam, yuav ua rau muaj kev cuam tshuam loj heev thiab ua rau muaj kev puas tsuaj loj heev.
Lwm hom kev ua tsis tiav yog tshwm sim thaum qhov kub ntawm cov node tshaj qhov melting point ntawm semiconductor silicon (1415 degree). Lub zog pulse ntawm hluav taws xob zoo li qub tuaj yeem tsim hluav taws xob tsim hluav taws xob hauv zos, yog li muaj kev cuam tshuam ncaj qha ntawm lub teeb thiab IC. Qhov tsis ua haujlwm zoo li no tshwm sim txawm tias qhov hluav taws xob qis dua qhov kev tawg ntawm qhov nruab nrab. Ib qho piv txwv zoo yog tias LED yog lub diode tsim los ntawm PN kev sib tshuam, thiab kev tawg ntawm cov emitter thiab lub hauv paus yuav ua rau qhov nce tam sim no txo qis. Tom qab lub LED nws tus kheej los yog ICs nyob rau hauv lub tsav Circuit Court raug cuam tshuam los ntawm hluav taws xob zoo li qub, kev ua haujlwm puas yuav tsis tshwm sim tam sim ntawd. Cov khoom uas raug puas tsuaj feem ntau tsuas yog tshwm sim thaum siv, yog li lub neej ntawm cov tshuaj ntsuam yuav raug cuam tshuam. Yog tuag.
