LED-based Traffic Signal Modules

The energy-saving benefits of LED outdoor lighting is in its infancy, but LED street lighting may represent the future giant gorilla for this LED application.

Programs to replace conventional traffic signals with LED fixtures are in full swing in many municipalities, and they are benefiting from reduced energy and maintenance.

In the largest contract for traffic signals by any US city for over twelve months (before Feb 2008), more than 70,000 Dialight LED signals will be used to replace traditional incandescent traffic signals throughout Miami-Dade County in Florida.

Brain Todd, vice president at Dialight says; "LED traffic signals use 90% less energy and last ten times longer than traditional incandescent traffic signals so this contract will bring major environmental benefits to Miami-Dade County. The additional benefit of our modules is that they can be retrofitted easily into the existing enclosures of the current energy inefficient incandescent lamps."

Dialight has supplied over two million LED traffic signals across the US over the last ten years. It is also the first company in the US to offer a comprehensive range of LED traffic signal modules that are fully compliant to the new ITE specifications. Dialight products include red, yellow and green modules using state-of-the-art high-flux LED technology.

In business since 1938, Dialight has been pioneering some of the most innovative applications in LED technology since it was developed in the early 1970s.

Dialight LED products for the electronics industry have given engineers better ways to indicate status on all kinds of equipment. Dialight LED traffic signals have saved municipalities millions of dollars in energy costs and maintenance, and LED signal and marker lights for heavy-duty vehicles often outlast the vehicles.

As a vertically integrated supplier, Dialight has the resources to design and produce everything in-house, supported by a global sales and distribution network.
