LED illumination device with single pressure cavity

A method for performing self-diagnosis in a light fixture comprising:

• by a processor:
• receiving data corresponding to a plurality of environmental conditions from one or more sensors, wherein the one or more sensors are positioned in a sensor cavity of a light fixture, and wherein a plurality of conduits provide a sealed path between a plurality of LED modules of the light fixture and the sensor cavity such that the LED modules, the conduits and the sensor cavity exhibit a plurality of environmental conditions;
• analyzing the data to determine if at least one of the plurality of environmental conditions has undergone one or more of the following changes:
• a change so that a value of the at least one environmental condition exceeds a threshold level,
• a threshold change compared to a corresponding constant level, or
• a rate of change that is greater than a threshold value;
• and
• in response to detecting a change that exceeds the threshold level, the threshold change or the rate of change that is greater than the threshold value, executing a corrective measure,
• wherein:
• the one or more sensors comprise an orientation sensor,
• the detected change comprises a change in orientation, and
• the corrective measure comprises causing a motor to adjust an orientation of the light fixture.
