Emergency traffic light system
First Claim
1. A visual warning assembly for disposal at an intersection of a plurality of roadways and comprising:
- a housing with first and second openings facing first and second directions transverse to one another;
a first light assembly positioned in said first opening and having a plurality of light emitting diodes arranged in pattern representing an emergency vehicle;
a second light assembly positioned in said second opening and having a plurality of light emitting diodes arranged in pattern representing an emergency vehicle;
a signal receiver physically supported by one of said housing and said first and second light assemblies and operable to receive and communicate a signal emitted by a signal emitter associated with an emergency vehicle; and
a controller physically supported by one of said housing and said first and second light assemblies and in communication with said first and second light assemblies and said signal receiver and, in response to receiving said signal from said signal receiver, operable to selectively direct power to said first and second light assemblies from a power source such that both can receive power from said power source but only one of said first and second light assemblies is illuminated at any particular time to limit power consumption and heat generation by said visual warning assembly and such that light is alternately flashed in said first and second directions.

Abstract
A visual warning assembly for disposal at an intersection of a plurality of roadways is disclosed herein. The visual warning assembly includes a housing with first and second openings facing first and second directions. The first and second directions are transverse to one another. The visual warning assembly also includes a first light assembly positioned in the first opening and having a plurality of light emitting diodes arranged in pattern representing an emergency vehicle. The visual warning assembly also includes a second light assembly positioned in the second opening and having a plurality of light emitting diodes arranged in pattern representing an emergency vehicle. The visual warning assembly also includes a signal receiver physically supported by the housings or one or both of the first and second light assemblies. The signal receiver or sensor is operable to receive and communicate a signal emitted by a signal emitter associated with an emergency vehicle. The visual warning assembly also includes a controller physically supported by the housing or one or both of the first and second light assemblies. The controller is in communication with the first and second light assemblies and the signal receiver. In response to receiving the signal from the signal receiver, the controller is operable to selectively direct power to the first and second light assemblies from a power source such that only one of the first and second light assemblies is illuminated at any particular time to limit power consumption and heat generation by the visual warning assembly.

6. A system for directing traffic at an intersection of a plurality of roadways and comprising:
-
at least one traffic light having a visual display for controlling movement of one or more vehicles at an intersection of a plurality of roadways; a vehicle operable to approach the intersection and having at least one light operable to flash intermittently or rotate or both and also having a signal emitter, wherein said signal emitter and said at least one light are operably coupled such that both operate concurrently; and first and second visual warning assemblies each spaced from said at least one traffic light and spaced from one another at opposite corners of the intersection, each of said first and second visual warning assemblies comprising; a housing with first and second openings facing first and second directions being transverse to one another; a first light assembly positioned in said first opening and having a plurality of light emitting diodes arranged in pattern representing an emergency vehicle; a second light assembly positioned in said second opening and having a plurality of light emitting diodes arranged in pattern representing an emergency vehicle; a power source operable to communicate power to said first and second light assemblies; a signal receiver physically supported by one of said housing and said first and second light assemblies and operable to receive and communicate said signal emitted by said signal emitter associated with said vehicle; and a controller physically supported by one of said housing and said first and second light assemblies and in communication with said first and second light assemblies and said signal receiver and, in response to receiving said signal from said signal receiver, operable to selectively direct power to said first and second light assemblies from a power source such that both can receive power from said power source but only one of said first and second light assemblies is illuminated at any particular time to limit power consumption and heat generation by said visual warning assembly and such that light is alternately flashed in said first and second directions.
