摘要： A method for performing self-diagnosis in a light fixture. The method includes receiving data corresponding to a plurality of environmental conditions from one or more sensors. The one or more sensors are positioned in a sensor cavity of a light fixture 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. The method also includes 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.
