Techniques for assessing condition of leds and power supply

摘要: Techniques are disclosed for assessing the conditions of LEDs and power supplies solid state lighting systems. The techniques can be used, example, to measure capacitance an output capacitor C in a switch-mode supply (SMPS), condition being driven by that supply. In some cases, this assessment implemented controller controls system, which may configured simultaneously determine LEDs. one example case, implemented, instance, micro-controller operating system. A system implementing periodically assessed so as provide real-time diagnostic capability. Numerous embodiments SMPS LED systems will apparent light disclosure.
