In the situation of energy shortage, the light source of lamps, which is one of the major consumers of electricity consumption, has become the focus of social attention. Promoting energy-saving lamps plays an important role in alleviating energy shortages and achieving sustainable development in China. From the current situation, energy-saving lamps have been installed in the road lighting of various promotion cities, and some landscape lighting has also been replaced with energy-saving lamps.
With the promotion of the government and enterprises, the popularity of energy-saving lamps is just around the corner. ??
Recently, the Chongqing Municipal Government and Philips Electronics (China) Group jointly launched the "Philips Chongqing Day" event, representing the latest road lighting technology CosmoPolis warm white light system settled in Chongqing, Chongqing became the second domestic installation of this energy-saving lighting system after Shanghai city. It is understood that the use of energy-saving lamps in various places is heating up.
"encirclement" incandescent lamp
The oil is tight and the coal is in a hurry. After overdraft of economic rapid development for more than 10 years, China's energy crisis has become increasingly prominent, and the energy shortage has become a bottleneck restricting economic development. As the lifeline of modern industry, commerce and civil use, the “electricity shortage†that has been frequent in recent years has caused considerable economic losses.
In the situation of energy shortage, the light source of lamps, which is one of the major consumers of electricity consumption, has become the focus of social attention. Statistics show that an energy-saving lamp produced strictly according to national standards consumes one-fifth of the electricity of ordinary incandescent lamps. In this way, the promotion of energy-saving lamps plays an important role in alleviating energy shortages and achieving sustainable development in China.
According to experts, incandescent light bulbs have low energy efficiency and can only convert 5% of the received electricity into light energy. Energy waste is very serious. Therefore, it is imperative to promote energy-saving lamps for "encirclement and suppression" incandescent lamps. At this year's EU spring summit, the EU countries reached a consensus and decided to gradually replace incandescent lamps with energy-saving lamps to reduce greenhouse gas emissions. Countries also intend to pass legislation to ban the production of incandescent bulbs in 2009.
In China, Qingdao City, Shandong Province recently issued a notice requesting all districts and municipalities, departments, and municipal units to vigorously promote the use of energy-saving lamps to ensure the completion of the task of promoting the use of 470,000 energy-saving lamps this year. By 2010, the use of incandescent lamps is prohibited. .
LED lights favored
At present, there are many types of energy-saving lamps on the market, and the technology is relatively advanced and environmentally friendly is to count LED lights. LED lights, ie semiconductor lighting, save 80% energy compared to incandescent lamps and 50% less energy than fluorescent energy-saving lamps. LED is the abbreviation of LED. Because it is a solid-state cold light source, it has the characteristics of low working voltage, low power consumption, high luminous efficiency and long life, which has become the new favorite in the field of lighting.
At present, the life of incandescent lamps is 1000-2000 hours, and the theoretical life of LED lamps is up to 100,000 hours. Compared with incandescent lamps, LED lamps can save more than 80% energy under the same brightness, and save more than 50% energy compared with fluorescent energy-saving lamps. . Chen Lianghui, an academician of the Chinese Academy of Engineering and a researcher at the Institute of Semiconductors of the Chinese Academy of Sciences, said: "As long as one-third of the incandescent lamps are replaced by semiconductor lamps, the country can save 100 billion kWh of electricity every year, equivalent to one year of power generation in the Three Gorges Project. â€
In the field of LED lighting, the Philips Lighting Group, which started with a light bulb, is undoubtedly at the forefront. Liang Hanfeng, vice president of Philips Lighting Group Greater China and general manager of China's business, introduced the mergers and acquisitions made by Philips. Last year, he acquired a high-power LED manufacturer, mainly producing chips for LED lighting, and completed lighting in Europe in the first quarter of this year. The acquisition of equipment manufacturer PLI, in March this year, also acquired Canada's LED commercial light source machine manufacturer TIR. He said with confidence: "LEDs are now mainly used for commercial decoration, and we believe that they can be used for general lighting soon."
The real application of LED to general lighting is the Sengu New Energy Company in Dalian. The white LED energy-saving fluorescent lamp, street lamp and solar-powered LED lighting system series developed by the company make white LED energy-saving fluorescent lamps and street lamps become a city municipal engineering and household lighting source. At the same time, the company is also the first domestic manufacturer to convert LED semiconductor light-emitting chip technology into public lighting products and successfully enter the market.
According to reports, the light efficiency of the 1 watt LED energy-saving fluorescent lamp produced by Sengu Company is equivalent to the light effect produced by the 25-watt ordinary fluorescent lamp, which is 70% more energy-efficient than the ordinary fluorescent lamp; its LED street lamp is 60% more energy-efficient than the ordinary street lamp, and the average trouble-free use time is up to More than 50,000 hours, the service life can reach 5 years.
Wu Qiliang, general manager of Beijing Exhibition Energy Saving Lighting Co., Ltd., said that the company was not professionally lighting. After understanding the LED lights, it found that the LED lighting market has great potential, so it was determined that the LED lighting products were represented. According to him, a 40W fluorescent lamp was used in a workshop of Shenzhen Lianchuang Hardware. After using the 5 LED lights provided by the company, the overall lighting effect is much improved. The company's next promotion will focus on street lighting projects.
Zhejiang Dayi Electronics Co., Ltd. made breakthroughs in the field of high-power LED lamps and obtained 6 related patents. All the streets in Shanmen Town, Pingyang County, Wenzhou City, Zhejiang Province were installed with LED lights produced by the company. Statistics show that Wenzhou's electricity consumption in 2006 was 21.161 billion kWh, accounting for 1/3 of lighting power consumption. If LED lights are used, electricity consumption can save at least 3 billion kWh, saving Xin'anjiang Hydropower Station for one year. Power generation.
Promoting energy-saving lamps has achieved results
Chen Deming, deputy director of the National Development and Reform Commission, said recently that China will further promote the use of energy-saving lamps and subsidize the institutions and units that purchase energy-saving lamps.
Under the call and encouragement of the Chinese government, various localities have launched plans to promote energy-saving lamps. Beijing has promoted energy-saving lighting products as an important task, and identified the green lighting project as an energy-saving project supported by the government, with a guiding capital of 20 million yuan. Through the demonstration and promotion of green lighting projects, the government invested a small amount of capital to mobilize the enthusiasm of suppliers, supplying at a price lower than 20% of the market, and driving the development of energy-saving industries. At the same time, Beijing also regulates the lighting market and establishes a quality service guarantee system, so that power-saving products are increasingly accepted by users.
Shandong, Yunnan, Gansu and other places are also vigorously promoting energy-saving lamps. From the current situation, energy-saving lamps have been installed in the road lighting of various promotion cities, and some landscape lighting has also been replaced with energy-saving lamps. With the promotion of the government and enterprises, the popularity of energy-saving lamps is just around the corner.
