UkuphephaUkonakala kwe-LEDlinyathelo elibalulekileyo ekuphuculeniUkuthembeka kwe-LED. Eli nqaku lihlalutya izizathu zokubola kwe-LED kwaye libonelela ngeendlela eziphambili zokuphepha ukubola - ukuphepha i-LED esondela kwizinto eziyingozi, kunye nokunciphisa ngokufanelekileyo izinga lokuxininisa kunye nokushisa kokusingqongileyo kwezinto ezinobungozi.

Ukuthembeka kweemveliso ze-LED yenye yezinto ezibalulekileyo ezisetyenziselwa ukuqikelela ixesha lokuphila kweemveliso ze-LED. Naphantsi kweemeko ezininzi ezahlukeneyo, iimveliso ze-LED ngokubanzi zinokuqhubeka nokusebenza. Nangona kunjalo, xa i-LED idliwe, ifumana ukuphendulwa kweekhemikhali kunye nokusingqongileyo, oku kunokukhokelela ekunciphiseni ukusebenza kwemveliso ye-LED.
Indlela efanelekileyo yokuphepha ukubola kwe-LED kukuthintela ukuba ingasondeli kwizinto ezinobungozi. Nokuba inani elincinci lezinto ezinobungozi zinokubangela ukubola kwe-LED. Nokuba i-LED idibana kuphela neegesi ezonakalisayo ngexesha lokusetyenzwa, njengoomatshini kwimigca yokuvelisa, isenokuba neziphumo ezibi. Kwezi meko, kuqhelekile ukuqwalasela ukuba ingaba iAmacandelo e-LEDzonakaliswe phambi kokuseta inkqubo yokwenyani. Ngokukodwa, ungcoliseko lwesulfure kufuneka luphetshwe.
Nantsi eminye imizekelo yezinto ezinokuthi zibe ngumhlwa (ingakumbi ihydrogen sulfide), kuquka:
O-Ringi
Iiwasha
Irabha yezinto eziphilayo
Iphedi yogwebu
Irabha yokutywina
I-elastomers eselenziwe ngesulfure equlethe isulfure
Iphedi efunxa ukothuka
Ukuba izinto ezinobungozi azikwazi ukuphetshwa ngokupheleleyo, i-LED ene-corrosion resistance resistance kufuneka isetyenziswe. Nangona kunjalo, nceda ukhumbule - umphumo wokunciphisa umhlwa uxhomekeke kugxininiso lwezinto ezinobungozi. Nokuba ukhetha ii-LED ezihlala ixesha elide, kuya kufuneka uzame ukunciphisa ukuvezwa kwezi zinto ze-LED.
Ngokuqhelekileyo, ubushushu, ukufuma kunye nokukhanya kunokukhawulezisa inkqubo yomhlwa. Nangona kunjalo, ezona zinto ziphembelelayo zisekumgangatho woxinzelelo kunye nobushushu bezinto ezinobungozi, kwaye ukunciphisa ezi zimbini ziya kuba ziindlela ezibalulekileyo zokukhusela ii-LED.
