In the context of global warming, the “low carbon economy†based on low energy consumption and low pollution has become a global hotspot. Developed countries in Europe and the United States vigorously promote the "low-carbon revolution" with energy efficiency and low emissions as the core, focus on the development of "low-carbon technology", and make major adjustments to industries, energy, technology, trade and other policies to seize the opportunities and industrial commanding heights. . The essence of low-carbon economy is the issue of energy efficient use, clean energy development, and the pursuit of green GDP. The core is the fundamental transformation of energy technology and emission reduction technology innovation, industrial structure and institutional innovation, and the concept of human survival and development.
To build a low-carbon city, we need to accelerate the development of industrial structure with the core of the cluster economy as the core; and promote energy-saving and emission reduction innovation with the circular economy as the core. Developing a low-carbon economy is a choice of economic development model. It means that the adjustment of energy structure, the adjustment of industrial structure and the innovation of technology are important ways for China to follow the path of sustainable development.
Developing a low-carbon economy is China's "world citizen" responsibility and a rare opportunity for China's sustainable development and transformation of its economic development model. The implementation of a low-carbon economy requires government leadership, including the formulation of a long-term strategy, the introduction of policies that encourage technological innovation, energy conservation and emission reduction, renewable energy use, tax exemption, financial subsidies, government procurement, green credit, etc. to lead and boost Low-carbon economy development; but it also requires enterprises to recognize the direction and consciously follow up and promote the "collective action" of low-carbon economic development. Only when more companies change the current passive state and consciously follow the development of low-carbon economy, China's transition to a low-carbon economy will have a realistic foundation and hope for the future.
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, lighting sources, which are one of the major consumers of electricity consumption, have become the focus of social attention. As an important part of the lighting industry, roads and landscape lighting account for 45-60% of the lighting power consumption in the whole country. Status is even more important. Therefore, in order to alleviate the national power shortage and reduce energy consumption, the promotion of power-saving projects in the field of major lighting energy consumption is related to the overall situation of energy conservation and consumption reduction.
Low carbon economy: the transformation that China must achieve
The first time in the past 30 years that climate change has been a global problem, the issue of carbon dioxide emissions has not been effectively addressed. In recent years, China's carbon dioxide emissions have increased rapidly. In 2008, it has surpassed the United States to become the world's largest carbon emitter. Zhongyuan Securities believes that in the short term, the US Clean Energy and Security Bill has been approved by the Senate, Obama will visit China in November, and the 15th UNFCCC Conference of the Parties and five pre-conferences will be held in Copenhagen in December. China's new energy industry development plan may be introduced during the year and other events and policies have prompted the low-carbon economy to become a hot spot at the end of 2009. In the long run, since 2009, the United States has repeatedly publicly requested that developing countries be included in the emission reduction system. The target is directed at China, and China's emission reduction pressure is increasing. It is only a matter of time before China establishes a market-based emission reduction system. The current rapid recovery of the domestic economy provides a good opportunity for the development of a low-carbon economy.
Energy-efficient lighting: usher in rapid development opportunities
Incandescent lamps consume about 7% of the world's total electricity consumption and 2% of total carbon dioxide emissions. Since 2007, most countries have formulated policy measures to promote the pace of replacing incandescent lamps with energy-saving lamps. By 2012, almost all developed countries will ban incandescent lamps. CITIC Jiantou believes that if the global incandescent lamp is changed to energy-efficient lamps from 2012 onwards, it will save 5.5% of electricity every year and reduce carbon dioxide emissions by about 5 million tons. At present, there are more than 15 billion incandescent lamps in the world. The ratio of incandescent lamps to energy-saving lamps is about 4:1. The penetration rate of energy-saving lamps is very low. Compared with incandescent lamps in China, the ratio of incandescent lamps to energy-saving lamps is about 7.5:1. The alternative space is huge. At present, the government has introduced a subsidy policy for the promotion of energy-saving lamps. At the same time, the “Opinions on the Development of Semiconductor Lighting Energy-Saving Industry†jointly announced by the National Development and Reform Commission and other six departments last month proposed that “by 2015, the average annual growth rate of semiconductor lighting (LED) energy-saving industry output value will be 30%. Left and right; product market share has increased year by year, functional lighting up to 20%, LCD backlights of more than 50%, landscape decoration and other products market share of more than 70%" and other goals, LED development prospects.
The LED light source has a long service life, rich colors, and energy saving, and is widely used. It is estimated that 81% of notebook computers will adopt LED backlight technology in 2010, and LED products in LCD TV and display fields will also accelerate penetration. With the global consensus on the development of a low-carbon economy, the LED industry will usher in rapid development opportunities with its performance advantages. The LED lighting market will usher in explosive growth. It is expected that the market size will reach 1.6 billion US dollars in 2012.
Energy-saving energy crisis traditional light source encounters global ban
China's current energy is mainly from thermal power generation, while thermal power generation uses oil and coal. As the price of oil continues to soar, the cost of power generation increases, and coal combustion produces a large amount of carbon dioxide, causing a greenhouse effect. In today's society where the energy crisis and greenhouses are becoming more and more serious, energy conservation and environmental protection have become the theme of lighting products. According to experts, the energy efficiency of traditional light sources is low, and only 5% of the received electricity can be converted into light energy, and energy waste is very serious. Therefore, it is imperative to disable traditional energy-consuming lighting sources and promote green energy-saving lighting. At this year's EU spring summit, EU countries reached a consensus and decided to gradually replace incandescent lamps with new energy-saving light sources to reduce greenhouse gas emissions. Countries also intend to pass legislation to prohibit the production of energy-consuming light sources in 2009. The light source has encountered a global ban.
In China, in July last year, the General Office of the State Council issued the "Notice on Establishing a Government's System for Compulsory Purchasing of Energy-Saving Products" (Guo Ban Fa [2007] No. 51), clearly stating that government agencies at all levels use fiscal funds for government procurement activities. When the indicators such as technology and services meet the procurement requirements, priority should be given to purchasing energy-saving products, and mandatory procurement should be implemented for products that meet the requirements for energy-saving effects and performance. In August, the Ministry of Construction also ordered that all cities should no longer use multi-light decorative garden lights in urban main roads. It is strictly forbidden to use powerful searchlights, high-power floodlights, large-area neon lights, color bubbles, and beautiful lamps. High brightness and high energy consumption lamps. In November, the State Council issued a document stipulating that from 2008 onwards, Chinese local provincial officials will begin to submit energy-saving answers to the central government. If the transcript fails to pass the exam, they will face accountability and “one-vote vetoâ€. In January this year, the Ministry of Finance and the National Development and Reform Commission jointly issued the Interim Measures for the Administration of Financial Subsidy Funds for Efficient Lighting Products Promotion to ensure the full implementation of high-efficiency energy-saving lighting products through financial subsidies during the 11th Five-Year Plan period.
Trend promotion LED green lighting has become a trend
At present, there are many energy-saving lighting products 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 light-emitting diode. 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, and has become the mainstream in the field of energy-saving 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, Qinshang Optoelectronics, which truly applies LEDs to general lighting and achieves mass production, is undoubtedly at the forefront. It is understood that Qinshang Optoelectronics and Tsinghua University have made major breakthroughs in high-power LED street lamps, and have obvious innovations. They have obtained more than 200 international and domestic invention patents and utility model patents, and have undertaken the Beijing Green Olympics road lighting project. Guangdong Science Center Square and surrounding road lighting project, road lighting project of Olympic venues in Tsinghua University, and comprehensive renovation projects of Shenzhen, Zhongshan, Dongguan Changping, Shipai and Shilong, occupying the leading domestic high-power LED industry through the application of Qinshang Optoelectronics Position, become the semiconductor lighting company with the largest number of industry model projects.
According to the “Eleventh Five-Year Planâ€, China will launch ten energy-saving projects in the future. Among them, green lighting and promotion of high-efficiency power-saving lighting systems will be an important content. Therefore, as the third lighting revolution after the open flame and incandescent lamps, semiconductor lighting (LED) will become the technological development trend in the next few years.
Upgrade traditional lighting for industrial upgrading
It is reported that with the promotion of the 2008 Beijing Olympic Games and the 2010 Shanghai World Expo, the market growth of China's LED industry will further accelerate in the next few years. Under the impetus of “National Semiconductor Lighting Projectâ€, Shanghai, Dalian, Nanchang, Xiamen and Shenzhen and other national semiconductor lighting engineering industrialization bases, it is estimated that by 2010, China's semiconductor lighting and related industries will reach 150 billion yuan, and LED as a light source into the general lighting market will become the core of future industrial development.
With the continuous maturity of the LED industry and technology, coupled with the support and guidance of national policies, many traditional lighting giants at home and abroad have invested in the development of semiconductor lighting, the industry reshuffle has further intensified, and the traditional enterprise industry upgrade is in the brow.
It is reported that in response to and implement the State Council's call for energy conservation and emission reduction, Dongguan City plans to complete the semiconductor lighting (LED) technology transformation of the city's street lamps within three years from 2007 to ease the contradiction between rapid growth in demand for electricity and tight supply of electricity. From the current statistics of Changping, Shijie, Shijie and other towns, the data statistics show that the newly installed high-power LED street lamps have obvious energy-saving and environmental protection effects. The application of Qinshang Optoelectronics high-power LED Street Light provides an effective way for Dongguan to complete the provincial government's target of 20% reduction in energy consumption per unit of GDP during the 11th Five-Year Plan period.
