    • Various embodiments may relate to a method for determining life expectancy information of an LED module with a plurality of LEDs. The method includes detecting of forward biases of the LED module at instants of time which lie less than 100 ms apart from each other, comparing a currently detected forward bias with one or more earlier detected forward biases, in order to detect a voltage jump which reaches a minimum initial inverse voltage within a predetermined jump duration, wherein the minimum initial inverse voltage is at least 60 mV and the predetermined jump duration is less than 100 ms long, and determining life expectancy information based on one or more detected voltage jumps.
    • 各种实施例可以涉及用于确定具有多个LED的LED模块的预期寿命信息的方法。 该方法包括在彼此相距小于100ms的时刻检测LED模块的正向偏压,将当前检测到的正向偏压与一个或多个较早检测的正向偏压进行比较,以便检测达到的电压跳变 在预定跳跃持续时间内的最小初始反向电压,其中所述最小初始反向电压至少为60mV,并且所述预定跳跃持续时间小于100ms长,以及基于一个或多个检测到的电压跳变来确定预期寿命信息。
