Rau LED cov ntxaij vab tshaus, cov neeg feem coob xav tias cov khoom tseem ceeb ntawm lub vijtsam, LED thiab IC, muaj lub neej ntev ntawm 100,000 teev.Raws li 365 hnub / xyoo, 24 teev / hnub ua haujlwm, kev pabcuam lub neej yog ntau tshaj 11 xyoo, yog li cov neeg siv khoom feem ntau tsuas yog xav txog kev siv lub npe zoo ntawm LEDs thiab ICs.Qhov tseeb, ob qho no tsuas yog cov xwm txheej tsim nyog, tsis muaj cov xwm txheej txaus, vim tias kev siv lub teeb liab, ntsuab thiab xiav yog qhov tseem ceeb dua rau lub vijtsam zaub.zaub yuav tseem ceeb dua.Kev kho kom tsim nyog ntawm IC kuj pab kom kov yeej qhov teeb meem tsis tsim nyog ntawm PCB
Cov yam tseem ceeb ntawm no yog:
Txij li cov LEDs thiab ICs yog cov khoom siv hluav taws xob semiconductor, lawv tau xaiv txog kev siv ntawm ib puag ncig, nyiam dua li ntawm 25 ° C ntawm chav tsev kub, thiab lawv cov txheej txheem ua haujlwm yog qhov zoo tshaj plaws.Tab sis qhov tseeb, ib qho screen loj sab nraum zoov yuav siv nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias, uas tej zaum yuav siab tshaj 60 ° C nyob rau lub caij ntuj sov thiab qis dua -20 ° C nyob rau lub caij ntuj no.
Thaum cov chaw tsim khoom tsim khoom, lawv siv 25 ° C raws li qhov kev xeem, thiab faib cov khoom sib txawv rau hauv qib.Txawm li cas los xij, qhov kev ua haujlwm tiag tiag yog 60 ° C lossis -20 ° C.Lub sijhawm no, kev ua haujlwm ntawm kev ua haujlwm thiab kev ua haujlwm ntawm LEDs thiab ICs tsis sib xws, thiab lawv tuaj yeem yog thawj qib.Nws yuav dhau los ua ntau theem, qhov ci ntsa iab yuav tsis sib haum, thiab lub vijtsam LED yuav ua rau pom tseeb.
Qhov no yog vim qhov ci ntsa iab attenuation thiab poob ntawm lub teeb liab, ntsuab thiab xiav sib txawv nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias.Ntawm 25 ° C, qhov nyiaj tshuav dawb yog qhov qub, tab sis ntawm 60 ° C, peb-xim LED Lub ci ci ntawm lub vijtsam tau txo qis, thiab nws cov nqi attenuation tsis sib haum, yog li qhov tshwm sim ntawm tag nrho lub vijtsam brightness poob thiab xim cam khwb cia. tshwm sim, thiab qhov zoo ntawm tag nrho lub vijtsam yuav txo qis.Thiab ua li cas txog IC?Kev khiav hauj lwm kub ntawm IC yog -40 ℃ -85 ℃.
Qhov kub hauv lub thawv nce vim qhov kub ntawm sab nraud.Yog tias qhov kub hauv lub thawv siab tshaj 85 ° C, IC yuav ua haujlwm tsis ruaj khov vim qhov kub thiab txias, lossis tam sim no ntawm cov channel lossis qhov sib txawv ntawm cov chips yuav loj dhau vim qhov kub sib txawv.coj mus rau Huaping.
Tib lub sijhawm, cov khoom siv hluav taws xob kuj tseem ceeb heev.Vim tias cov khoom siv hluav taws xob muaj qhov sib txawv ntawm kev ua haujlwm ruaj khov, cov nqi hluav taws xob tso tawm thiab lub peev xwm thauj khoom nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias, vim tias nws yog lub luag haujlwm rau kev txhawb nqa logistical, nws lub peev xwm txhawb nqa ncaj qha cuam tshuam rau lub vijtsam zoo.
Tus tsim ntawm lub thawv kuj tseem ceeb heev rau lub vijtsam zaub.Ntawm ib sab, nws muaj kev ua haujlwm ntawm kev tiv thaiv hluav taws xob, ntawm qhov tod tes, nws muaj kev ua haujlwm ntawm kev nyab xeeb, thiab tseem muaj kev ua haujlwm ntawm plua plav thiab dej tsis zoo.Tab sis qhov tseem ceeb tshaj yog seb qhov kev tsim ntawm lub voj voog thermal rau qhov cua thiab cua sov dissipation yog qhov zoo.Nrog rau qhov txuas ntxiv ntawm lub sijhawm khau raj thiab qhov nce ntawm qhov kub ntawm sab nraud, cov thermal drift ntawm cov khoom tseem yuav nce ntxiv, ua rau cov duab tsis zoo.
Cov yam tseem ceeb no yog txhua yam cuam tshuam thiab yuav cuam tshuam rau qhov zoo thiab lub neej ntawm cov zaub.Yog li ntawd, thaum tus neeg siv khoom xaiv qhov screen, nws kuj yuav tsum tau soj ntsuam thiab txheeb xyuas kom meej thiab txiav txim siab kom raug.
