Oriental Pearl in the end is how to save electricity 80%?

Qin Oujuan intern reporter Wang Chun scorching summer, hot weather continued to make our many local electricity and water in an emergency, at the moment, such naturally become the focus of attention, many large and medium-sized city have closed landscape lights, avoid peak electricity, to save energy. Recently, however, it was found that the size of the Shanghai Oriental Pearl TV Tower on the size of the ball is not only more bright stars, but also constantly changing color, how is this going on? Originally, the Oriental Pearl Tower is equipped with a high efficiency and energy-saving lamp, and the total power of light is reduced by more than and 100 kilowatts. Energy saving "new clothes" new where?

According to the Oriental Pearl TV Tower Co. Ltd. Engineering Manager Pan Wenjie said, the Oriental Pearl Tower has a total of 576 points to 576 points LED light, now all be transformed a replacement, such as bean shaped lights up the TV Tower the size of the sphere, before the transformation, each point of the optical power consumption of 200 watts, transformation after the power consumption of each optical point decreased to 70 watts, only this one will save 65% of the electricity reform, plus improvement of control system and other floodlight lamps, preliminary calculations than previously saved nearly 75% of electricity consumption.

Pan manager said, this kind of small bean sprouts is a semiconductor light-emitting device LED (LightEmittingDiode), LED is a light emitting diode, it can be red, yellow, blue three basic colors of the deployment of hundreds of thousands of colors. LED the use of electronic and light output diode gap with the energy conversion process, the semiconductor light source as a new solid cold light source, with its high efficiency, energy saving, environmental protection, triggered a worldwide and a lighting incandescent lamp and fluorescent lamp after the revolution. In particular, the life of the LED is very long, it is through the light source controller, the sun will be stored in the day, then released in the evening, so that the cycle can be used to run 60 days, the most critical thing is that it is very electricity.

The application of LED is very wide, including in backlight, lighting, electronic equipment, display, automotive and other five areas, has become the preferred electronic equipment indicator, at present almost all electronic devices have LED figure.

The Oriental Pearl TV Tower is the first use of LED energy efficient lighting construction, with LED, the luminous body diameter of cross section of basketball is so big, a power source is only 50 watts, lighting power down 75%%, luminous effect is much better, only this one will be the total power of the Oriental Pearl Light the reduced more than and 100 kw. The Oriental Pearl, which can be used for more than and 800 hours a day, can be used by the residents of the city for 4 hours every night.

Energy saving "new clothes" do not save money?

Energy saving lamps, but it may be said that energy-saving lamps, saving money, because the price is more than ten times or even several times the ordinary incandescent. In this regard, the Oriental Pearl Project Manager Pan Wenjie said, the whole set of equipment and efficient energy-saving lamps and Pearl installation fee is about 3000000, the price is not high, high efficiency energy-saving lamps to replace incandescent lamp, saving 70%-80%, and life is several times the ordinary incandescent lamp, from the long-term economic point of view, these funds the investment is worth.

Landscape lighting is considered to be the "night of Shanghai dressing beautician, created a" bustling and charming city night ". According to statistics, if all light engineering in Shanghai open, power consumption will be up to 200 thousand kilowatts. With the increasingly tense power, power consumption in the energy and artificial city, Shanghai, will choose the latter, no longer create artificial luster". Widely used in the city in order to save energy for the characteristics of green lighting, so that the landscape lighting bright and not luxury.

Energy saving engineering far-reaching significance

Experts pointed out that if the Shanghai high energy consumption lamps are replaced, can reduce the peak load of 6620 kilowatts of electricity, the annual saving up to 7 million kwh, the annual electricity savings of 4000 tons of coal, energy conservation has important and extensive impact on the relative scarcity of natural resources Shanghai Mega city. According to statistics, at present, China's annual electricity for lighting close to 250 billion kwh, this year's power gap climbed to 20 million kilowatts. In recent years, Shanghai's electricity consumption is growing. 2004, the city's electricity consumption reached 82 billion 144 million kwh, an increase of 10.1%, but also to rely on other energy resources in Shanghai province. Building a conservation oriented society, accelerate energy conservation and development of renewable energy, Shanghai is imperative.

So far, a lot of public walkways in Shanghai have used the LED energy saving technology. Said Hu Yanzhao, former vice mayor of Shanghai City, Shanghai in Huaihailu Road, the Bund and other places have started landscape lamp, street lamp energy-saving lighting project demonstration, the highest saving rate can reach 90% in the next three years, the landscape of the Huangpu River in the technological transformation, change the part of the building with the light, light pollution and excessive waste of energy with the implementation of scientific and reasonable exceed the standard problem, energy saving and environmental protection, beautiful elegant and harmonious goal. It is reported that, at present, the "Shanghai street lamp guide" is being drafted, the two sides of the Bund landscape lighting energy-saving programs are being developed, by the global environment fund (GEF) and the United Nations Development Programme (UNDP) supported by the "China green lights project" is in force, in the green lighting demonstration project. 420 thousand, Shanghai cumulative promotion of efficient lighting, 53 units to participate in. In foreign countries, Paris Eiffel Tower, Mexico, Morocco, a number of landmark buildings have been carried out landscape lighting transformation
