Nws yeej ib txwm muaj ib kauj ruam nyob rau hauv cov txheej txheem ntawm R & D, zus tau tej cov LED teeb, uas yog, siab thiab tsis kub aging test. Vim li cas thiaj yuav tsum tau LED teeb yuav raug rau siab thiab qis kub aging test?
Nrog rau txoj kev loj hlob ntawm cov cuab yeej siv hluav taws xob, kev sib koom ua ke ntawm kev tsav tsheb fais fab thiab LED nti hauv cov khoom siv hluav taws xob LED yog siab dua thiab siab dua, cov qauv yog ntau dua thiab hloov maj mam, cov txheej txheem ntau dua, thiab cov txheej txheem tsim khoom yog ntau thiab ntau dua. , uas yuav ua rau qee qhov tsis xws luag hauv kev tsim khoom. Thaum lub sij hawm tsim khoom thiab kev tsim khoom, muaj ob hom teeb meem ntawm cov khoom zoo los ntawm kev tsim tsis tsim nyog, cov khoom siv raw lossis cov txheej txheem ntsuas:
Thawj qeb yog tias qhov kev ua tau zoo ntawm cov khoom tsis yog raws li tus qauv, thiab cov khoom tsim tawm tsis ua raws li kev siv;
Qhov thib ob yog qhov muaj peev xwm tsis xws luag, uas tsis tuaj yeem pom los ntawm cov kev sim dav dav, tab sis yuav tsum tau maj mam nthuav tawm hauv cov txheej txheem ntawm kev siv, xws li cov pa phem, cov ntaub so ntswg tsis ruaj khov, vuam kab noj hniav, tsis zoo sib xws ntawm cov nti thiab lub plhaub thermal kuj thiab lwm yam. ntawm.
Feem ntau, cov teeb meem no tsuas tuaj yeem qhib tau (tshwj xeeb) tom qab cov khoom siv ua haujlwm ntawm lub zog ntsuas thiab ntsuas kub ua haujlwm li 1000 teev. Pom tseeb, nws yog qhov tsis muaj tseeb los ntsuas txhua qhov sib xyaw rau 1000 teev, yog li nws yog qhov tsim nyog los siv cov cua sov kev ntxhov siab thiab kev tsis ncaj ncees, xws li kev ntsuas kub ntawm lub zog hluav taws xob, txhawm rau txhawm rau txhawm rau ua rau muaj qhov tsis xws luag thaum ntxov. Uas yog siv thermal, hluav taws xob, mechanical lossis ntau yam kev ntxhov siab sab nraud rau lub teeb, simulate qhov chaw ua haujlwm hnyav, tshem tawm cov kev ntxhov siab, cov kuab tshuaj seem thiab lwm yam khoom, ua rau qhov tsis zoo tshwm sim ua ntej, thiab ua rau cov khoom dhau los ntawm thawj theem. cov yam ntxwv da dej tsis raug sai li sai tau thiab nkag mus rau lub sijhawm ruaj khov ruaj khov.
Los ntawm kev kub siab kev laus, qhov tsis xws luag ntawm cov khoom thiab cov kev phom sij zais cia uas muaj nyob hauv cov txheej txheem tsim khoom xws li vuam thiab sib dhos tuaj yeem raug nthuav tawm ua ntej. Tom qab kev laus, kev ntsuas kev ntsuas tuaj yeem nqa mus rau kev tshuaj ntsuam thiab tshem tawm cov khoom ua tsis tiav lossis hloov pauv, txhawm rau tshem tawm qhov tsis ua haujlwm thaum ntxov ntawm cov khoom ua ntej siv ib txwm siv kom deb li deb tau, txhawm rau xyuas kom meej tias cov khoom xa tuaj tuaj yeem sawv qhov kev sim ntawm lub sijhawm. .
Tam sim no tag nrho cov khoom siv hluav taws xob yuav tsum tau ua kom tau raws li cov av noo ib puag ncig kuaj
Kev ntsuas av noo feem ntau yog ua los xyuas seb puas muaj cov khoom tawg yooj yim thiab cov khoom siv hauv cov khoom tsim kom sai li sai tau, thiab seb puas muaj cov txheej txheem teeb meem lossis hom tsis ua haujlwm, txhawm rau muab kev siv rau kev txhim kho cov khoom tsim qauv. Txhawm rau kom ntseeg tau qhov kev ua tau zoo ntawm cov khoom, ntau qhov ntsuas kub thiab av noo thiab lub sijhawm sib txawv yuav raug siv rau hauv kev sim. Thaum lub sijhawm no, qhov kev xeem ntawm txhua theem yuav tsum dhau thiab ua tau raws li qhov yuav tsum tau ua.
Qee cov ntaub ntawv hygroscopic yooj yim, xws li cov ntawv luam tawm, cov yas extrusion, ntim cov khoom, thiab lwm yam, yuav nqus dej ncaj qha rau qhov siab thiab lub sij hawm raug dej vapor. Thaum cov khoom nqus dej ntau dhau, nws yuav ua rau muaj kev nthuav dav, muaj kuab paug thiab luv luv Circuit Court, thiab tseem ua rau kev ua haujlwm ntawm cov khoom puas tsuaj, Piv txwv li, cov dej ntws tawm los ntawm qee qhov rhiab circuits thiab ua rau cov khoom tsis ua haujlwm. Qee cov tshuaj residues tuaj yeem ua rau muaj kev cuam tshuam loj heev ntawm cov laug cam lossis hlau nto oxidation vim dej vapor. Qee zaum, qhov cuam tshuam ntawm electron tsiv teb tsaws ntawm cov kab uas nyob ib sab kuj yuav tshwm sim los ntawm cov dej vapor thiab qhov sib txawv ntawm qhov sib txawv los ua dendritic filaments, uas ua rau cov khoom tsis ruaj khov thiab lwm yam teeb meem.
Yog tias cov khoom muaj cov teeb meem zoo li no, ntau yam kev ntsuam xyuas ib puag ncig yuav tsum tau ua kom nrawm qhov tshwm sim ntawm cov txheej txheem tsis ua haujlwm, kom nkag siab txog cov ntsiab lus teeb meem ntawm cov khoom.
Wellwaykuaj kuaj muaj Programmable kub & humidity chamber, uas muaj peev xwm simulate qhov kev hloov ntawm kub thiab av noo nyob rau hauv txawv cheeb tsam thoob plaws hauv lub xyoo los ntawm qhov kev pab cuam. Lub tshuab hluav taws xob tas li kub kom qhuav qhov cub thiab ntsuas kub thiab av noo tuaj yeem ua tiav qhov kev txwv ntawm cov khoom siv hluav taws xob hauv LED teeb nyob rau hauv ib puag ncig sib txawv thiab pom cov teeb meem tshwm sim ntawm cov khoom. Sim peb qhov zoo tshaj plaws los muab cov neeg siv khoom nrog cov khoom lag luam teeb pom kev zoo thiab ruaj khov.
