Design of new traffic lights: Traffic safety and maintenance ease

When a LED array needs to be replaced or a traffic light needs repair, the traffic in one lane must be interrupted and lifts are needed to elevate the repairman, with all the danger that this involves, in addition to the economic cost and the traffic disruption caused. We have designed an illumination system for a traffic-light model in which the LED array is located at the base of the traffic light and from this emerges a bundle of optical fibers connected to the illumination plate of the traffic light. We seek to improve traffic safety and possibly achieve lower costs.
