OUTDOOR LIGHTING FIXTURES FOR CONTROLLING TRAFFIC LIGHTS
First Claim
1. An outdoor lighting fixture for communicating with a traffic light system, the outdoor lighting fixture comprising:
- a ballast for providing current to at least one lamp;
a fixture housing at least partially surrounding the ballast and the at least one lamp;
a mount configured to hold the fixture housing to a pole;
a control circuit wired to the ballast;
a sensor wired to the control circuit; and
a radio frequency transceiver wired to the control circuit;
wherein the control circuit is configured to process inputs from the sensor to determine whether to send a light change instruction to the traffic system via the radio frequency transceiver.

Abstract
An outdoor lighting fixture for communicating with a traffic light system is shown and described. The outdoor lighting fixture includes a ballast for providing current to at least one lamp and a fixture housing at least partially surrounding the ballast and the at least one lamp. The outdoor lighting fixture further includes a mount configured to hold the fixture housing to a pole and a control circuit wired to the ballast. A sensor and a radio frequency transceiver are wired to the control circuit. The control circuit is configured to process inputs from the sensor to determine whether to send a light change instruction to the traffic system via the radio frequency transceiver.

7. A system for controlling a traffic light at an intersection of a first street and a second street, comprising:
-
a first street light oriented to illuminate the first street and having a first motion sensor pointed to detect vehicle traffic on the first street; a second street light oriented to illuminate the second street and having a second motion sensor pointed to detect vehicle traffic on the second street; a command system for the traffic light, wherein the first street light and the second street light communicate detected vehicle traffic on the first street and the second street to the command system via radio frequency transceivers of the first street light and the second street light, and wherein the command system changes the traffic light based on the detected vehicle traffic on the first street and the second street. - View Dependent Claims (8, 9, 10, 11)
