Whether for traffic lights or message panels, the use of LED traffic signals is increasingly widespread in both permanent and portable, battery-operated systems with photo-voltaic panels. In addition to the basic display function – with ambient light sensors to adjust for brightness – traffic signals can be connected to a control center for re-programming and monitoring purposes and might have GPS tracking to enable effective monitoring and maintenance.

We offer a complete range of LED driving and AC-DC and DC-DC conversion solutions together with environmental MEMS sensors and 32-bit STM32 microcontrollers as well as wireless and wired connectivity solutions to help develop  advanced traffic signal solutions.
