Lighting system with illuminance control

A motorized service vehicle for measuring a light illuminance of an outdoor luminaire, comprising:

• a light sensor mounted on a motorized service vehicle and configured to detect the light illuminance generated by the outdoor luminaire,
• a service device controller operatively coupled to the light sensor for receipt of a measured light illuminance signal and compute light illuminance data for the outdoor luminaire based thereon;
• and at least one of:
• a data communication unit configured to transmit the light illuminance data to the outdoor luminaire through a wireless communication link to the outdoor luminaire;
• and
• a data recording device configured to store the respective light illuminance data of the plurality of outdoor luminaries.

A method of setting or adjusting light illuminance of an outdoor luminaire from a bypassing motorized service vehicle;

• the method comprising steps of:
• driving the motorized service vehicle to a road position within an illumination zone of the outdoor luminaire,
• detecting a light illuminance generated by a controllable light source of the outdoor luminaire by a light sensor mounted on the motorized service vehicle,
• comparing the detected light illuminance to a predetermined or nominal light illuminance of the luminaire,
• computing light illuminance data for the outdoor luminaire based on the comparison,
• transmitting the computed light illuminance data from the motorized service vehicle or from a remote central server to the outdoor luminaire through a wired or wireless communication link,
• adjusting a light illuminance of the controllable light source in accordance with the received light illuminance data by a light source controller operatively coupled to the controllable light source.
