Recently, held in Chicago in the fourth session of the U.S. department of energy (doe) solid-state lighting symposium, outdoor LED lighting, especially in the LED street light has been widely concerned. Title is not only eye-catching discussion, there are questions about outdoor lighting all kinds of training and interpretation, etc.
Why so interested? The simple answer is that although the whole solid-state lighting technology in the initial cost to compete over traditional lighting technology is still a long way to go, but solid state lighting in outdoor lighting applications has shown a strong competitive force. This is because policymakers have seen the solid-state lighting in energy saving, environmental protection, the advantages of easy control and aesthetic effect, etc.
It's easy to see how the application of solid state lighting and some other high maintenance cost the product difference and advantage. Other states through the federal block grants to the subordinate local municipal bonds or funds, believe streets and parking lot will soon be a large number of application of LED lighting lamps and lanterns.
How to evaluate and choose the LED street lighting products? This seminar in Chicago emphasized explains. Alaska anchorage Michael Barber introduced their experience achievement of street lighting. Their 4000 LED lights, street lighting installed than high voltage sodium lamp energy saving more than 75%, so that they can take back all the investment within 7 years. Michael also analyzed when the LED light failure, not easy die lamp, important problems such as how to cut down the price.
But Scott from Oakland, California say a lot of difficult problems, such as Oakland GATEWAY demonstration project with excessive lighting over - lighting problem. Scott pointed out that compared with the existing technology, they will be able to implement security lighting level with less light. Many speakers also spoke about the problem of excessive lighting, including Derry Berrigan lighting designers, he recently completed the LED installation of McDonald's, though less than 70% of the level of ASHRAE, but reached a satisfactory level security lighting,
CRS electronic Scott Riesebosch pointed out that there are nearly 200 suppliers of LED street light, completely don't know how to choose them. Dan Weinheimer said a thing or two, in SAN marino, California, held two test of LED street light. Dan suggest people not to pay attention to the initial cost too much and more attention to the overall cost efficiency, in addition, he also points out that the important factors that affect people decided to other (e.g., SAN marino, the department of public safety for LED lighting at night can improve the color to identify preferred).
Wal-mart's Ralph Williams also spoke about the same problem, they in Kansas levin worth parking lot LED lights is better than high voltage sodium lamp control and management, and more uniform. LED lighting energy consumption reduced by 65% and save the maintenance cost, installation cost, in particular, because of the high pressure sodium lamp to replace once every two years. Ralph also cautioned solid-state lighting didn't also necessary are installed on all the wal-mart parking lot, consider store size, local laws and factors such as acquisition cost, in order to decide whether to install, this is not a simple project.
At the Chicago conference, participants learn from each other each other's experience. Everyone interested in LED street lighting problem is discussed, and the U.S. department of energy (doe) intends to set up municipal solid state lighting alliance to share technical information and experience. These companies will take advantage of all aspects of the achievement to assess the state-of-the-art LED lighting products, will also be collected, analyzed and joining members information sharing. Membership will be for the government, utilities and energy open, more details can refer to the department of energy sites.
Municipal solid state lighting alliance will make full use of solid-state lighting seminar in Chicago with all the doe, is learn by each other to speed up the development technology. If we take advantage of everyone's mutual learning, can continue to stay on top of twists and turns. Don't need anyone or repeated efforts in the dark; Share information and experience to make our roads become capacious and bright.
