Tom qab LED tawg-pov thawj lub teeb raug tua, lub teeb yuav flash, txawm tias thaum hloov pauv txuas nrog cov hlau nyob. Yog vim li cas:
Qhov no yog vim tias tom qab kab nruab nrab N yog hauv av, nws tsis pom qhov zoo 0V, uas yog, qhov nruab nrab taw tes hloov pauv tshwm sim, uas ua rau cov kab nruab nrab N muaj qhov sib txawv rau hauv av, thiab tom qab ntawd muaj yuav yog qhov voltage hauv kab. Lub induced voltage yog tsim, thiab nyob rau tib lub sij hawm, nws yuav flash tom qab lub switching yog muab tua. Nyob rau lub sijhawm no, tsuav yog qhov nruab nrab thiab nyob ntawm cov xov tooj ntawm qhov tawg-pov thawj lub teeb hloov pauv tag nrho, nws tuaj yeem rov qab mus rau qhov qub. Los yog tsuas yog txuas lub teeb lub teeb kab ncaj qha mus rau hauv av xaim.
Afterglow tshwm sim, uas yog, yuav muaj lub teeb tsis muaj zog tom qab lub LED raug kaw, thiab nws yuav siv sijhawm ntev los tua:
Yog vim li cas rau qhov tshwm sim yog tias nyob rau hauv ib txwm muaj xwm txheej, LED tawg-pov thawj lub teeb tsis ncaj qha los ntawm cov xaim nruab nrab thiab cov xaim nyob, thiab lub DC transformer me me yuav raug ntxiv ntawm ob. Muaj ib txwm muaj qhov tsis muaj zog txaus, thiab ib zaug qhov hluav taws xob ntau tshaj 0.37V (qhov tsawg kawg nkaus induced voltage ntawm LED lub teeb), lub teeb yuav ib txwm nyob, kom txog rau thaum qhov seem voltage tsawg dua 0 .37V, nws yuav tawm mus.
Tom qab lub teeb tawg-pov thawj raug tua, yeej ib txwm muaj qhov tshwm sim tsis muaj zog. Cov laj thawj tshwm sim yog raws li nram no:
1. Nws yog qhov ua tau tias lub teeb yuav khoom nws tus kheej yog hom nrog qhov taw qhia lub teeb, thiab kev paub tsis tau them nyiaj rau;
2. Yog tias nws tsis yog thawj zaug, nws yuav yog qhov Circuit Court ntawm lub teeb ci LED yog me ntsis los yog muaj lub teeb me me ntawm qhov hloov;
3. Lwm qhov muaj peev xwm yog qhov hloov ntawm LED tawg-pov thawj lub teeb txuas nrog cov hlau tsis huv. Lub sijhawm no, nws tsuas yog yuav tsum tau hloov qhov hloov mus rau kev tswj cov hlau nyob;
Kev paub ntxiv: Dab tsi yog induction nthwv dej:
1. Nyob rau hauv ib lub voj kaw, qhov tam sim no nyob rau hauv uas generated magnetic teb cuam tshuam qhov kev hloov ntawm magnetic flux ntawm lub qub magnetic teb yog hu ua induced xov tooj cua yoj;
2. Lub hauv paus ntsiab lus ntawm generating induced tam sim no: Tus neeg xyuas pib muab tso rau hauv qhov hloov magnetic flux yog kaw rau hauv ib lub voj, thiab lub electromotive quab yuam yuav tsav cov electrons ntws, tsim ib qho induced tam sim no (induced tam sim no 0). Nyob rau hauv layman cov ntsiab lus, thaum ib feem ntawm tus neeg xyuas pib ntawm lub voj kaw yog nyob rau hauv magnetic teb los txiav cov magnetic teb kab, tag nrho cov hlau nplaum flux ntawm kaw lub voj yuav twv yuav raug hloov, thiab ib tug induced electromotive quab yuam yuav generated nyob rau hauv lub kaw voj. , thiab Ronger yuav tsim ib qho tam sim no. ua tus induced tam sim no.
Tom qab nkag siab lub tswv yim ntawm induced tam sim no, koj puas muaj kev nkag siab txog cov laj thawj yog vim li cas LED tawg-pov thawj teeb yuav entangled nyob rau hauv cov xwm txheej saum toj no: nws zoo li cov khoom siv hluav taws xob hlau ntawm koj Motong Electric, txawm hais tias nws yog insulated los ntawm lub fais fab mov, tab sis nws ib txwm loog rau qhov kov. ntawm. Qhov no txhais tau hais tias thaum koj txiav tawm lub hwj chim, tseem muaj me ntsis induced hluav taws xob nyob rau hauv Circuit Court ntawm cov khoom siv hluav taws xob. Kev daws rau qhov tshwm sim no kuj yooj yim heev. Txuas lub resistor nyob rau hauv parallel nrog lub davhlau ya nyob twg LED kom tso tawm cov seem tam sim no.
