A self-adjusting luminaire (100) whose primary operation is to provide ambient or focused lighting in a hazardous environment is configured to modify (e.g., continuously) the energization intensity levels of its on-board illumination sources (108a, 108n) based on magnitudes of difference between an amount of light in the environment of the luminaire (e.g., including both light produced by the luminaire and ambient light) as measured by on-board sensors (130) and a setpoint amount of light corresponding to the luminaire. Further, the self-adjusting luminaire may detect that its on-board sensors are malfunctioning when the illumination sensors fail to sense a change in the amount of light in the environment of the luminaire after the luminaire has modified the energization intensity levels of its illumination sources. Upon detecting a sensor malfunction, the self-adjusting luminaire may generate an alarm, and/or may automatically modify the intensity of its illumination sources to mitigate effects of the detected malfunction.

Event indications of hazardous environment luminaires using visual sequences
A luminaire whose primary operation is to provide ambient or focused lighting in a hazardous environment is further configured to communicate, within the hazardous environment, alert and/or detected events or conditions via visual sequences. Different visual sequences uniquely identify respective alerts and/or detected conditions, which may include conditions occurring at the luminaire and/or conditions occurring within the hazardous environment. Different visual sequences are defined by respective blink sequences stored in a blink sequence library at the luminaire. Blink sequences are configurable, are distinguished by different amplitudes, frequencies, duty cycles, and other energization/de-energization waveform characteristics, and are applied to one or more illumination sources of the luminaire to thereby generate corresponding visual sequences in the hazardous environment. Visual sequences generated by hazardous environment luminaires allow personnel within the hazardous environment to be informed or alerted to critical conditions upon their occurrences, even without the use of a portable computing device.
