Summary:Apparatus and systems are disclosed for detecting outages in an LED lamp assembly. An example disclosed lamp assembly includes a plurality of LED circuits serially connected together. The LED circuitsinclude an LED, a first resistor and an optocoupler. The example disclosed lamp assembly also includes a sense line electrically coupled to one of the LED circuits. The sense line has a first voltagevalue when all of LEDs in that plurality of LED circuits are operational and a second voltage value when at least one of the LEDs has failed. 公开了用于检测LED灯总成的中断的装置和系统。所公开的示例灯总成包括串联在起的多个LED电路。LED电路包括LED、第电阻器和光耦合器。所公开的示例灯总成还包括电连接到LED电路中的个的感测线。当该多个LED电路中的所有LED都可操作时，感测线具有第电压值，并且当至少个LED已经发生故障时，感测线具有第二电压值。
