Abstract: Packaged light emitter module can provide improved safety features to facilitate sensing the presence of moisture or a mechanical defect such as a crack in a transmissive cover (22) that may result in a safety hazard caused by the emitted light (24) if the defect or other situation is not addressed in a timely manner. Different electrically conductive structures, such as different electrically conductive traces (20, 22), allow monitoring and detection of mechanical defects to be decoupled from monitoring and detection of problems arising from the presence of moisture. The decoupling can allow the respective configuration for each of the electrically conductive structures to be optimized for detection of particular situations that may lead to a safety hazard.
