Lighting system for a stadium
First Claim
1. A light system for a stadium, the light system comprising:
- at least one sensor configured to determine light intensity values for multiple locations within the stadium;
multiple electronically controllable luminaires, wherein at least one electronically controllable luminaire is configured to generate light directed towards at least one location of the multiple locations within the stadium based on a received control parameter;
a controller configured to receive the light intensity values from the at least one sensor, further configured to determine a light intensity difference based on the light intensity values from the multiple locations within the stadium, and configured to select the at least one electronically controllable luminaire and generate the control parameter for the at least one electronically controllable luminaire based on the light intensity difference to attempt to reduce the light intensity difference;
wherein the at least one sensor comprises at least two cameras, each camera located at a different known position within the stadium and configured to view the multiple locations from different viewing orientations such that each camera is configured to determine a light intensity value directional component for each location;
wherein the light intensity value for each location comprises at least two directional components representing the light intensity as sensed from two separate directions respectively, and the light intensity difference is based on a difference between a combination of the light intensity values for each location from each direction.
