The United States and American: LED lights lead the new trend of outdoor lighting
Currently in the United States, outdoor lighting and the amount of the total electricity generating capacity accounts for about 4.4%. It is precisely because of this situation, the U.S. House of Representatives recently introduced a new motion to call for the phasing out of old low-efficiency technologies (such as incandescent and halogen lamps) for energy-efficient, more cost-effective new lighting technologies (such as high brightness LED) to pave the way for the development.

At the global level, on to government agencies, industrial and commercial areas, down to the general public are actively seeking an effective way to reduce power consumption. Primarily on the first attempt to achieve the goal easily, for example, select the appropriate insulation materials for residential use of solar panels and energy conservation and so forth. Today, there are relatively sound legal provisions, requires that we must use energy-efficient white appliances, adapters and chargers, consumer electronics and office equipment. In recent years, high-brightness LED With the ever decreasing cost, people have begun to standards such as light bulbs and other household products before accepting a re-appraisal. In many countries (including the United States, Germany, Britain, Ireland and Australia), the newly established energy efficiency standards have risen for the law, would effectively prohibit the continued use of incandescent lighting.
U.S. House of Representatives, California, No. 36 constituency Members JaneHarman in March 26, 2009 speech, proposed a "Outdoor Lighting Energy Efficiency Act," the bill aims to resolve the issue of street lighting to phase out standard light bulbs. Harman said: "by improving the energy efficiency of the energy savings achieved will be very striking. According to an authoritative industry estimates that the implementation of this Act, the ultimate outdoor lighting will reduce energy use by more than 25% per year more than 60 billion dollars to save electricity costs. This figure is equivalent to more than 50 coal-fired power plant generating capacity. "
House of Representatives passed the new proposal, the first phase of the standard will be completed in 2011, followed by the standard will be completed in 2013 and completed in 2015. By then, the U.S. Department of Energy will further enhance the energy efficiency standards. The bill also requires the brightness of outdoor lighting must be controlled in order to facilitate the users to change their light-emitting volume, because people in the evening and late night hours and the required level of brightness is different. This feature is important because it will give the cities, towns and other users of their consumption level greater control over it. The bill is based on California laws have been implemented, as well as other states have already adopted standards for outdoor lighting.
LED street lights appeared to be the earliest dating back to the'90s, then, the city authorities have begun the design of the use of solid-state lighting to replace incandescent traffic lights. In order to also achieve the LED traffic lights in its street lighting system energy and maintenance savings, in many cities (including Michigan AnnArbor) have carried out a wide range of LED pilot lamps. In AnnArbor, estimated that after the installation of LED lamps, each year the city will save more than 100,000 U.S. dollars in electricity costs can be reduced each year about 294 tons of greenhouse gases (CO2) emissions. These results seem to indicate repetition, City Museum will be following the old incandescent traffic lights shortly after the use of high-pressure sodium and high-intensity discharge (mercury vapor) street lamps, as the installation of LED lamps in North America, China and Europe is a common phenomenon.
LED lighting system is the major advantage of long life, LED can last 10 to 15 years, at least three times that of traditional street life. Only in low maintenance rate, LED on to become a very attractive option. In addition, as LED technology of its own characteristics, to precisely control the amount of light required, and can be placed through the LED and optical optimization to adjust the light direction, compared with previous products, LED's energy efficiency level 50 percent higher to 80 %. Moreover, LED or mercury lamps, which is increasingly concerned about environmental protection of the world, no doubt, is a major bright spot.
Further advantage is, LED can provide a very uniform light distribution, not only conforms to current standards, but also to eliminate bright spots and glare. This is to ensure that a good lighting effects, drivers and pedestrians at the same time reduce visual fatigue, and to do this and do not have any energy. Since the LED is in the low pressure and low temperature conditions, and therefore with the growth in working hours, they will not yellow or clear decline in brightness. In addition, the difference is that with the sodium lamp, LED lamps can be no time delay to achieve the best light, so that they can improve the lighting effects, with the Clinton Climate Action Plan (CCI) under the "Outdoor Lighting Plan" is currently being carried out in cooperation with the Los Angeles, will be conducted in Los Angeles, the largest cities in the history of the development of LED street lighting improvement works. Outdoor lighting CCI also partners with a number of cities through the integration of technical, procurement and project support to improve the street lighting and traffic signal system on the level of energy efficiency. Los Angeles street Authority over the next five years will be the city's 140,000 street-lamp current for the LED lamps to replace. Remote monitoring stations will report directly to the Authority streetlights fault conditions automatically, thereby reducing street maintenance downtime and improve efficiency. According to the Authority estimated that the implementation of the scheme of the seven-year period, the city will save 48 million U.S. dollars in electricity costs and reduce the 197,000 tons of carbon emissions. Once the investment pay off the loan (first loan will be borne by the current energy and maintenance cost savings to bear part of), the street reconstruction project this year in Los Angeles will be 10 million U.S. dollars to save expenses. The enormity of this project will not only become the streets of Los Angeles was ablaze with lights and reduce electricity consumption and save money, but also reduce the light pollution (also known as sky glow).
