Signal Applications With LEDs

The advancements in InGaAlP & GaN technology have fostered the adoption of LEDs in a variety of outdoor applications including traffic signals. Today, nearly 50% of all LED traffic signal installations are supported by electric utility subsidy pr ograms. Almost every major city in North America and abroad is using LEDs in traffic signal applications. LEDs offer enormous benefits over traditional incandescent lamps including:

• Energy savings (up to 85% less power than incandescent
• Reduction in maintenance costs. LEDs lifespan averages 7-10 years
• Increased visibility in daylight and adverse weather conditions

In addition, Sanken Optoelectronics offers LEDs that are designed to meet the requirements of VTCSH (Vehicle Traffic Control Signal Heads) issued by the ITE (Institute of Transportation Engineers) as well as the European Standard EN12368:2000
