Abstract
A technique for determining when to replace protection circuitry in electronic devices, such as lighting fixtures, is provided. Protection circuitry is provided between AC supply rails and in front of circuitry to be protected. A protection circuit sensor is located and configured to measure a characteristic of the protection circuitry and provide a corresponding sensor output. Control circuitry will monitor the sensor output of the protection circuit sensor on a continuous, periodic, or aperiodic basis. Next, the control circuitry will determine at least one metric indicative of an extent of damage inflicted on the protection circuitrybased on the sensor output. Based on the at least one metric, the control circuitry will determine when the at least one metric exceeds a threshold indicative of a need to replace the protection circuitry while the protection circuitry remains operational.
