LED Signals

LED Signals

LED rail signals replace incandescent units to better meet the critical 24/7 reliability needs of railway and transit operators. Benefits of advanced LED technology in these 365-day-a-year devices include recurring energy savings and lower maintenance.

In recent years, LED technology (Light Emitting Diode) has spread rapidly finding applications of inquestionable interest in the railway signalling industry. The strength of these devices is based on their potential to be brighter, more efficient and more reliable than the incandescent lamps.

Their high switching speed and manufacturing technology compatible with that of silicon chips make them ideal for realization of devices extremely versatile in their use. LED signals are characterized by technological innovation that can bring significant economic and operational benefits in the management of railway signals, creating interesting economic opportunities for operators.
