STREET LIGHTING DEVICE FOR COMMUNICATING WITH OBSERVERS AND ASSOCIATED METHODS

摘要

A thoroughfare lighting device comprising a housing configured to be attached to a thoroughfare surface, a plurality of LEDs configured to selectively illuminate individual lanes of the thoroughfare surface, the plurality of LEDs comprising a first set of LEDs configured to emit a generally white light and a second set of LEDs configured to emit colored light that is operable to selectively emit light so as to illuminate individual lanes of the thoroughfare surface, a driver circuit configured to operate the second set of LEDs to emit a colored light indicating the condition of a first lane of the thoroughfare surface, and an optic carried by the housing and positioned in optical communication with the plurality of LEDs.

主权项

1. A thoroughfare lighting device comprising:
a housing configured to be attached to a thoroughfare surface; a plurality of light-emitting diodes (LEDs) configured to selectively illuminate individual lanes of the thoroughfare surface, the plurality of LEDs comprising:
a first set of LEDs configured to emit a generally white light, anda second set of LEDs configured to emit colored light that is observable by an observer that is operable to selectively emit light so as to illuminate individual lanes of the thoroughfare surface; a driver circuit electrically coupled to the plurality of LEDs and configured to operate the second set of LEDs to emit a colored light illuminating a single lane of the thoroughfare surface indicating the condition of the individual lane of the thoroughfare surface; and an optic carried by the housing and positioned in optical communication with the plurality of LEDs.
