Airfield Ground Light with Integrated Light Controller That Employs Powerline Communications and Sensors

An apparatus, comprising:

• a controller operable to communicate with a plurality of airfield lighting fixtures, the controller comprises logic comprising a processor operable to:
• receive data representative of sensor data, the sensor data selected from a group consisting of vibration signals from the plurality of airfield lighting fixtures and data representative of a plurality of temperatures from the plurality of airfield lighting fixtures;
• and
• determine a status of a selected one of the plurality if lighting fixtures, the status selected from a group consisting of a structural integrity based on a comparison of the plurality of vibration signals and determining whether the vibration signal from the selected one of the plurality of lighting fixture indicates the selected one airfield lighting fixture is vibrating more than other airfield lighting fixtures from the plurality of airfield lighting fixtures, and a fixture malfunction based on a comparison of temperature data from the selected one of the plurality of airfield lighting fixtures with other airfield lighting fixtures of the plurality of airfield lighting fixtures.

An airfield luminaire, comprising:

• a housing;
• a light source in an interior of the housing;
• a temperature sensor;
• a pressure sensor;
• control logic comprising a processor coupled with the light source, the temperature sensor, and the pressure sensor and a memory for storing data representative of a previous temperature measurement and data representative of a previous pressure measurement, the control logic is operable to:
• obtain data representative of a temperature from the temperature sensor;
• obtain data representative of a pressure from the pressure sensor;
• and
• determine if there is a leak in the housing by comparing changes in temperature with changes in pressure.

An airfield luminaire, comprising:

• a housing;
• a light source in an interior of the housing;
• a temperature sensor;
