Integrated LED Traffic Signal
The future of LED traffic signaling
Dialight introduces an innovative new traffic signal head that improves energy efficiency,
readily adapts to power supply changes and delivers lower maintenance costs than traditional
LED ball and arrow signal modules. A pioneer in LED technology for 40 years, Dialight was
among the first to offer LED traffic signals in the mid-1990s. Dialight’s new integrated traffic
signal head represents the first major innovation in the field since the rollout of LED.
Simplified Signal Replacement
The timing of the new traffic signal head’s release can benefit organizations that
install and maintain signals since many units currently in use are more than 20 years old and
thus well beyond the end of their recommended life cycle. Dialight’s unique new product
enables replacement of older units with a head that integrates LED signals into the housing;
unlike other products on the market, this facilitates replacement of existing units with a single
purchase and does not require the assembly in the field, of an LED module into a traffic
signal head.
Efficiency
Dialight’s new traffic signal head also offers greater operational efficiency, consuming less than seven watts as compared to existing LED
units, which consume up to 30 watts, and older incandescent signals, which use up to 165 watts. The new integrated traffic signal
housing is sealed against moisture and is backed by a 15-year warranty, with 1 power supply replacement recommended during the
warranty period or with optional 15-year long life power supply, consult factory for more information.
Compatibility, Forward and Backward
The integrated traffic signal head is fully compatible with the wiring and mounting hardware that supports existing signal units. Unlike other
products on the market, Dialight’s integrated traffic signal head is designed for maximum flexibility, featuring a replaceable power
supply that allows users to accommodate initiatives such as conversion to DC voltage to enhance public safety. With the integrated
Dialight product, the conversion can be accomplished by simply replacing the power supply rather than replacing the entire LED
traffic signal module.
The new product, for which multiple patents are pending, will be offered in standard housing colors, and the efficient LED signals
provide vivid red, yellow and green lighting in ball and arrow configurations. The new head is designed to comply with the current ITE
optical and electrical requirements.
By offering the first innovation in traffic signal technology in well over a decade, Dialight, an industry pioneer, continues to lead the way,
providing more efficient, cost-effective and flexible options.
