Recent advances in LED street lights in the United States: has been widely recognized

The day before the fourth session held in Chicago, the United States Department of energy solid state lighting symposium, especially outdoor LED lighting LED lamp has been widely concerned. Not only has the purpose of discussing the title, but also the training of outdoor lighting and problem solving.

Why are you so interested? The answer is very simple, although the overall solid state lighting technology in the initial cost to compete with the traditional lighting technology still has a long way to go, but the solid-state lighting in outdoor lighting applications have shown strong competitiveness. This is because policymakers have seen the advantages of solid-state lighting in energy conservation, environmental protection, ease of control and aesthetic effects.

It is easy to see the differences and advantages of solid state lighting and other products with high maintenance costs. In addition, the state government through the federal debt down to the local city issued a classification of financial subsidies or grants, I believe the streets and parking lot will soon be a large number of LED lighting.

How to evaluate and select LED street lighting products? This focus on the Chicago seminar explained. California Anchorage city MichaEL Alaska Barber introduced the achievements of their experience of street lighting. Their street lighting installed 4000 LED lights, more than 75% energy saving, so that they can recover all the investment within the next 7 years. Michael also analyzed LED what time decay, death is not easy to light, how to reduce the price of important issues.

But Scott from California, Oakland, revealed many difficult issues, such as the GATEWAY demonstration project in Oakland and the problem of over lighting over-lighting. Scott pointed out that, compared to the existing technology, they can achieve a safe lighting level with less light. In addition to multiple speakers also talked about the problem of excessive lighting, including the Derry Berrigan lighting designer, he completed the installation of McDonald's LED recently, although lower than ASHRAE grade 70%, but reached a satisfactory level of security lighting,

CRS electronics ScottRiesebosch pointed out that there are currently nearly 200 LED street lights suppliers, do not know how to choose them. Dan Weinheimer said one or two things, California San Marino city held two LED streetlights test. Dan suggests that people don't excessive focus on the initial cost, and pay attention to the overall cost efficiency more, he also pointed out that other important factors affecting people's decisions (such as the Public Security Department of San Marino at LED lighting to improve color recognition favored a plus).

WAL-MART's Ralph Williams also talked about the same problem, they better control and management of LED lights in Kansas's Levin worth parking lot than the high-pressure sodium lamp, but also more uniform. LED lighting energy consumption reduced by 65%, and save maintenance costs, especially installation costs, because the high-pressure sodium lamp to be replaced every two years. Ralph is careful to say it is not necessary for solid state lighting are installed in the parking lot all the WAL-MART, but also consider the store size, the local law and the purchase cost and other factors, in order to decide whether to install, this is not a simple project.

At the Chicago meeting, participants learn from each other's experiences. To explore the interest in the LED street lighting, the U.S. Department of energy plans to set up a municipal solid state lighting alliance to share technical information and experience. These companies will use all aspects of the achievements of the assessment of the art class LED lighting products, will also collect, analyze and share information. Membership will be open to government, public utilities and the Department of energy.

Municipal solid state lighting alliance will make full use of Chicago and all of the Department of energy solid state lighting seminar, that is, through learning from each other to speed up the development of technology. If we learn to take advantage of each person's will be able to stay in the top with many twists and turns. There is no need for anyone to work in the dark or repeat; sharing information and experience will make our way bright and spacious.
