Problem uppst\u00e5r ofta vid anv\u00e4ndning av LED. LED-svetsade produkter b\u00f6rjar fungera korrekt, men efter en viss tid blir ljuset m\u00f6rkt, flimmer, det uppst\u00e5r fel eller intermittent ljus, vilket orsakar allvarliga skador f\u00f6r produkterna. Orsakerna till detta fenomen \u00e4r:<\/p>\n

2. Sj\u00e4lva LED:en, kvalitet eller tillverkningsprocess.<\/p>\n

\u00c5ldrande \u00e4r en viktig garanti f\u00f6r tillf\u00f6rlitligheten hos elektroniska produkter och det sista, avg\u00f6rande steget i produktionen. LED-produkter kan f\u00f6rb\u00e4ttra prestandan efter \u00e5ldrande och bidra till den senare prestandastabiliteten. LED-br\u00e4nningstest \u00e4r en mycket viktig del av produktkvalitetskontroll, men det ofta f\u00f6rbises i m\u00e5nga fall, vilket leder till att det inte utf\u00f6rs korrekt. Testet tar h\u00e4nsyn till produktnedsattningskurvan, som badkarraskurvan, f\u00f6r att f\u00f6rb\u00e4ttra produktens tillf\u00f6rlitlighet. Denna metod \u00e4r dock inte obligatorisk, eftersom \u00e5ldrandetestet inneb\u00e4r en offrande del av enskilda LED-produkters levnadstid.<\/p>\n
