Outdoor Lighting: LED Roadway wins Edmonton project, Kingsun supplies Shenzhen

In a mix of new and retrofit applications, LED Roadway Lighting is supplying the city of Edmonton, Canada with 2580 Satellite series LED luminaires. Kingsun Optoelectronic has completed one of the first large-scale LED roadway lighting projects in China deploying solid-state lighting (SSL) along a 120-km highway. Las Vegas, Nevada has begun an LED retrofit project that could reach 50,000 street lights, and we have more details on the Bristol, UK project that utilizes Philips SpeedStar luminaires.

In Edmonton, the city projects that the SSL project will deliver $2.6 million in energy savings over the expected 20 year life of the luminaires. The projection is based on 51% savings over the high-pressure sodium (HPS) fixtures that are currently in use. The local electric utility Epcor Utilities worked with the city to specify the LED luminaires.

Over the 20 year period, the city projects a reduction of 12,880 tonnes of greenhouse gas emissions. Moreover the aggregate electricity savings total 16,000,000 kWh.

”This project represents one of our largest deployments in Canada, and reinforces our message that municipal and other users are interested in reliability and are serious about conducting a total life cycle cost evaluation,” said LED Roadway Lighting CEO Charles Cartmill. “We are very excited about the future, and for this current opportunity to supply our fixtures to the City of Edmonton.”

Kingsun supplies 10,000+ luminaires

In Shenzhen, China, Kingsun has supplied more than 10,000 SSL luminaires for a roadway lighting project along a 120-km highway with three traffic lanes and an emergency lane in each direction. The project include both pole-mounted roadway lights and tunnel lights.

The Shenzhen project was a new roadway lighting project rather than a retrofit. Kingsun supplied 239W LED lights for the roadway where it's likely that 400W HPS lights would have been required for the project. Kingsun said the LEDs will deliver 60% energy savings.

The roadway lighting is deployed in a median belt that isolates the opposing traffic lanes. Each pole includes arm mounted luminaires on each side. Kingsun says the average illumination is more than 20 lx.
