Tsis txhob xeb ntawm LEDs yog ib feem tseem ceeb ntawm kev txhim kho kev ntseeg siab ntawm LEDs. Kab lus no txheeb xyuas qhov ua rau corrosion ntawm LEDs, thiab muab cov hau kev tseem ceeb kom tsis txhob muaj kev xeb-kom tsis txhob LEDs ze rau cov khoom tsis zoo, thiab txo qis cov concentration ntawm cov khoom tsis zoo thiab qhov kub thiab txias.
Q: Yuav ua li cas kom tsis txhob LED corrosion?
Keywords: LED, corrosion, khoom ua tau zoo, optoelectronic Cheebtsam
Kev ntseeg tau ntawm cov khoom siv LED yog ib qho tseem ceeb tshwj xeeb uas siv los kwv yees lub neej ntawm LED khoom. Txawm tias nyob rau hauv ntau qhov sib txawv, cov khoom siv LED tuaj yeem ua haujlwm ntxiv. Txawm li cas los xij, ib zaug LED raug corroded, LED yuav raug tshuaj lom neeg cov tshuaj tiv thaiv nyob rau hauv ib puag ncig ib puag ncig, uas yuav txo qhov kev ua tau zoo ntawm cov khoom LED.
Txhawm rau kom tsis txhob xeb ntawm LED, txoj hauv kev zoo tshaj plaws yog kom tsis txhob LED los ze rau cov khoom tsis zoo. Txawm tias me me ntawm cov khoom tsis zoo tuaj yeem ua rau LED corrosion. Txawm hais tias LED tsuas yog nyob rau hauv kev sib cuag nrog corrosive gas thaum lub sij hawm ua, xws li lub tshuab nyob rau hauv cov kab ntau lawm, tej zaum yuav muaj kev phiv. Nyob rau hauv cov ntaub ntawv no, nws yog feem ntau ua tau los soj ntsuam seb cov LED Cheebtsam puas puas ua ntej lub teeb system tiag tiag. Tshwj xeeb, yuav tsum tsis txhob ua qias neeg los ntawm sulfur (Sulfur).
Nov yog qee qhov piv txwv ntawm cov khoom muaj peev xwm corrosive (tshwj xeeb yog hydrogen sulfide) suav nrog:
O-RING (O-RING)
lub tshuab ntxhua khaub ncaws
Organic Roj Hmab
ua npuas ncauj
Roj hmab sealing
Sulfur-muaj vulcanized elastomer
Shock absorbers
Yog tias qee yam khoom tsis zoo tuaj yeem zam tsis tau tag nrho, LEDs nrog kev tiv thaiv corrosion ntau dua yuav tsum tau siv. Txawm li cas los xij, thov nco ntsoov - cov txiaj ntsig ntawm kev txwv corrosion nyob ntawm qhov concentration ntawm cov khoom tsis zoo. Txawm hais tias koj xaiv cov LEDs ruaj khov dua, koj yuav tsum txo qis qhov cuam tshuam ntawm cov khoom siv LED no.
Feem ntau, tshav kub, av noo thiab lub teeb tuaj yeem ua kom cov txheej txheem corrosion. Txawm li cas los xij, qhov cuam tshuam tseem ceeb yog qib concentration thiab qhov kub thiab txias ntawm cov khoom tsis zoo, thiab kev txwv ob qho no yuav yog ib txoj hauv kev tseem ceeb los tiv thaiv LEDs.
