UkugwemaUkugqwala kwe-LEDkuyisinyathelo esibalulekile ekuthuthukiseniUkuthembeka kwe-LED. Lesi sihloko sihlaziya izizathu zokugqwala kwe-LED futhi sinikeza izindlela eziyinhloko zokugwema ukugqwala - ukugwema i-LED esondela ezintweni eziyingozi, kanye nokukhawulela ngokuphumelelayo izinga lokuhlushwa kanye nokushisa kwemvelo kwezinto eziyingozi.

Ukuthembeka kwemikhiqizo ye-LED kungenye yezicaciso ezibalulekile ezisetshenziselwa ukulinganisa ubude bempilo yemikhiqizo ye-LED. Ngisho nangaphansi kwezimo eziningi ezihlukene, imikhiqizo ejwayelekile ye-LED ingaqhubeka nokusebenza. Kodwa-ke, uma i-LED igqwalile, ibhekana nokusabela kwamakhemikhali nendawo ezungezile, okungaholela ekwehleni kokusebenza komkhiqizo we-LED.
Indlela engcono kakhulu yokugwema ukugqwala kwe-LED ukuyivimbela ukuthi ingasondeli ezintweni eziyingozi. Ngisho nenani elincane lezinto eziyingozi lingabangela ukugqwala kwe-LED. Ngisho noma i-LED ihlangana kuphela namagesi abolayo phakathi nokucubungula, njengemishini emigqeni yokukhiqiza, isengaba nemiphumela emibi. Kulezi zimo, kuvame ukubonwa ukuthi ngabe i-Izingxenye ze-LEDzonakaliswa ngaphambi kokusethwa kwesistimu kwangempela. Ikakhulukazi, ukungcola kwesibabule kufanele kugwenywe.
Nazi ezinye izibonelo zezinto ezingase zibe ukugqwala (ikakhulukazi i-hydrogen sulfide), okuhlanganisa:
O-Ring
Amawasha
Irabha ephilayo
Iphedi legwebu
Irabha yokuvala uphawu
Ama-elastomers anesulfure aqukethe isulfure
Iphedi ebamba ukushaqeka
Uma izinto eziyingozi zingenakugwenywa ngokuphelele, i-LED enokumelana nokugqwala okuphezulu kufanele isetshenziswe. Kodwa-ke, sicela ukhumbule - umphumela wokunciphisa ukugqwala uncike ekugxilweni kwezinto eziyingozi. Ngisho noma ukhetha ama-LED ahlala isikhathi eside, kufanele uzame ukunciphisa ukuchayeka kwalezi zinto ze-LED.
Ngokuvamile, ukushisa, umswakama, nokukhanya kungasheshisa inqubo yokugqwala. Kodwa-ke, izici eziyinhloko ezinomthelela kuseyizinga lokuhlushwa kanye nezinga lokushisa lezinto eziyingozi, futhi ukukhawulela lezi zinto ezimbili kuzoba izindlela ezibalulekile zokuvikela ama-LED.
