Abstract: A signal is received at a monitoring device from a photodetector. The signal conveys a characteristic of radiation received by the photodetector from an exit piece of a luminaire, through which exit piece light emitted by the luminaire exits the luminaire. Based on the characteristic, the monitoring device is used to determine a dirt level on the exit piece. A geographic location associated with the luminaire is identified based on a geographic proximity of the geographic location to the luminaire. In response to an increase in the determined dirt level, the monitoring device generates a control signal which causes an object at the geographic location that is separate from the luminaire to be cleaned.
