LIGHT ALIGNMENT SYSTEM FOR ELECTRONICALLY STEERABLE LIGHT OUTPUT IN TRAFFIC SIGNALS

摘要

A solid state traffic control signal adapted to facilitate light alignment and viewing angles during installation. The traffic control signal includes a video camera or a detachable optical sighting system with a grid representing the various viewing angles of individual LED's for quick alignment and viewing angle programming. This system greatly reduces the amount of trial-and-error and multi-man requirements for installation.
