Abstract
A system includes at least one light-emitting device configured to be mounted on a stationary structure, such as a lighting pole or parking structure. A control circuit is operatively coupled to the at least one light-emitting device and configured to detect an object in a vicinity of the at least one light-emitting device and to vary a characteristic of illumination produced by the at least one light-emitting device responsive to the detection of the object.
