LED Traffic Signals

 LED traffic signal applications may cover a very wide range, from portable or permanent traffic message signs to solar-powered traffic lights and signals. In addition to the LED driving section, the most advanced systems require smart sensing and timing for reliable applications, connectivity capability for remote programming and monitoring, and GPS tracking for cost effective maintenance. For energy efficient applications, solar energy can be used to supply the whole system. STMicroelectronics offers a wide and high performance product portfolio to meet these system design needs.
