Abstract: A system for light source calibration and aging compensation is disclosed. In one or more embodiments, the system includes a light source driver, a sensor, and a controller. The light source driver is configured to generate one or more power signals for a plurality of light sources. The sensor is configured to detect an illumination power output by at least one light source of the plurality of light sources. The controller is communicatively coupled to the sensor and the light source driver. The controller is configured to compare the illumination power detected by the sensor to a target illumination power. The controller is further configured to generate one or more control signals to adjust an electrical power output of the light source driver based on the comparison of the illumination power detected by the sensor to the target illumination power.

Abstract: An aircraft interior power converter comprises electronic circuitry that includes a primary power converter operative to convert an AC input power supply to a primary DC output power supply, a regulator for at least one of the DC output voltages required, the regulator being operative to receive the primary DC output power supply and generate a DC input power supply at the voltage required for a particular DC outlet connected to that regulator. An output protection circuit is provided for each DC outlet and is operative to receive a DC input voltage. Each output protection circuit comprises a comparator circuit that generates a load signal indicative of the electrical load being taken by that DC outlet, compares that load signal against a predetermined load limit, and generates an output control signal to disconnect the DC input voltage from the DC outlet if the load signal exceeds the predetermined load limit.
