The present invention discloses a method, system, and computer readable medium for configuring an electronically steerable beam of a traffic signal light (). The system comprises a wireless device () adapted to send at least one command to change a viewing angle of the traffic signal light (), and a control unit () adapted to receive the command, the control unit () further adapted to send the command to the traffic signal light (), wherein the command adjusts a viewing angle of at least a portion of the traffic signal light ().

System and method for configuring an electronically steerable beam of a traffic signal light

A solid state light apparatus ideally suited for use in traffic control signals provided with optical feedback to achieve a constant light output, preferably by detecting back-scattered light from a diffuser centered above an LED array. The control logic allows for the LEDs to be individually driven, and having their drive characteristics changed over time to ensure a uniform beam of light is generated at an intensity meeting DOT standards, across the life of the device. The optical feedback also establishes the uniform beam intensity level as a function of sensed ambient light to discern day and night operation.
