6. Halayen attenuation
Bayan nunin LED ɗin ya yi aiki na dogon lokaci, hasken zai ragu kuma launin nunin zai kasance mara daidaituwa, wanda galibi yakan haifar da haɓakar haske na na'urar LED. Attenuation na LED haske zai rage haske dukan LED nuni allon. Rashin daidaituwa na haɓakar haske na LEDs ja, kore da shuɗi zai haifar da rashin daidaituwa na launi na nunin LED. Fitilolin LED masu inganci na iya sarrafa girman haɓakar haske. Dangane da ma'auni na 20mA hasken wuta a dakin da zafin jiki na 1000 hours, ja attenuation ya kamata ya zama kasa da 2%, da blue da kore attenuation ya zama kasa da 10%. Don haka, gwada kada ku yi amfani da 20mA na yanzu don shuɗi da koren LEDs a cikin ƙirar nuni, kuma yana da kyau a yi amfani da kawai 70% zuwa 80% na halin yanzu.
Baya ga halayen haɓakawa da suka danganci halayen ja, kore da shuɗi LEDs kansu, abubuwan da ake amfani da su a halin yanzu, ƙirar ɓarkewar zafi na hukumar PCB, da yanayin yanayin yanayin allon nuni duk suna shafar attenuation.
