Abstract
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.
