Global government promotes energy-efficient lighting
   Global energy prices are rising, and energy conservation has gradually become the focus of attention of all countries. Lighting consumption is an important part of global energy consumption. According to the data provided in the US Solid State Lighting Technology Project, the energy consumption of all lighting in the United States in 2001 was about 8.2 quads, accounting for 22% of total energy consumption. According to statistics, lighting electricity accounts for about 12% of China's total electricity consumption. It can be said that lighting is an important part of energy saving and emission reduction projects. How to improve the efficiency of lamps has become the focus of attention of the government, the scientific community and the business community.
   Currently popular emerging lighting technologies include LED, OLED, and energy-saving lamps. Energy-saving lighting has great commercial potential due to the active promotion of governments and the rising energy prices. Governments have spared no effort in promoting emerging technologies, such as the US “Solid State Lighting†program, Europe’s “OLED100.eu†program, Japan’s “21st Century Lighting†program, South Korea’s “GaN Semiconductor Development†program, and China’s “Ten Citiesâ€. Wan Hao" project and so on.
Solar cells gradually enter the public life
   In recent years, together with the LED industry, there is also a solar photovoltaic technology. With the maturity of the production process of crystalline silicon and thin film solar cells, solar cells have gradually entered the public life.
   Looking at the world, the EU is the region with the largest photovoltaic power generation in the world. In 2008, photovoltaic power generation in the region accounted for 80% of the global total, of which Germany and Spain accounted for 84% of the EU total. The EU expects photovoltaic power generation to account for 12% of the EU's total electricity generation by 2020.
   As of June 2008, there are more than 40 polysilicon material manufacturers in China, more than 70 silicon ingots and wafer companies, more than 40 battery manufacturers, and more than 500 component and application companies. At present, there are 10 overseas listed solar cell companies in China, and one company listed in China, many companies are preparing to go public. In 2007, China has become the world's largest producer of solar cells.
   Compared with the rapid development of production enterprises, China's photovoltaic application market is developing slowly. The installed capacity in 2006 was 10MWp, and in 2007 it was 20MWp. 98% of the solar cells produced in China are exported to foreign countries, and the domestic solar energy application market is in urgent need of development.
   LED lighting popularizes rapid mass production efficiency up to 100lm/w
   Since 2008, the LED lighting market has shown an accelerated development trend. As of the beginning of 2009, the lighting efficiency of mass production chips of foreign famous Cree, Osram, Lumileds and other famous manufacturers have reached 100lm/W, which exceeds the efficiency of traditional energy-saving lamps. 80lm/W). The mass production efficiency of domestic chip manufacturers has also reached 80lm/W.
   The US "Solid State Lighting Plan" has strengthened the research and development of LED, OLED and other technologies through government funding and achieved fruitful results. Since 2010, the EU has banned the sale of high-energy household lighting equipment, including incandescent lamps, in the European Union. In 2006, Japan completed the replacement of 50% of traditional lighting with white LED lighting. It is planned that the luminous efficiency of LEDs will reach 120 lm/W by 2010. In early 2009, the Ministry of Science and Technology of China launched the “Ten Cities and Ten Thousand Miles†project, with the goal of replacing 6 million street lamps in 21 cities by the end of 2011. The plan will drive 15 billion yuan of domestic demand business opportunities.
   Taiwan Industrial Technology Institute predicts that the LED market for lighting will reach 630 million US dollars in 2009, up 35% from 2008. According to the statistics of StrategiesUnlimited, the development of global LED indoor lighting will show an exponential growth trend in the next five years, and the output value will reach tens of billions of dollars in 2011. Wu Ling, secretary-general of the National Semiconductor Lighting Engineering R&D and Industry Alliance, believes that the LED market in mainland China is expected to reach $100 billion in 2010.
   The new favorite of solar LED lighting energy-saving lighting
   Solar LED lighting combines the advantages of two "green technologies" of photovoltaics and LEDs, and quietly rises in the market. The key to the perfect combination of these two technologies is that the photovoltaic cells generate direct current, and the LED Light Source uses direct current, which removes the problem that bothers the LED and the commercial power. Traditional lamps must be combined with photovoltaic cells and must be converted to alternating current. This process increases losses and hinders the popularity of solar lamps.
   According to an experiment conducted by the American Lighting Research Center, in a photovoltaic cell plus battery system, the efficiency of the LED is as high as 45 lm/W, and the overall system efficiency is higher than that of the linear fluorescent tube. As long as it reaches 68 lm/W, it can exceed the compactness. System efficiency of fluorescent tubes. The white LEDs currently on the market can reach more than 80lm/w, and all the traditional lighting technologies have been exceeded in system efficiency.
   Nowadays, the market of solar LED Lamps is becoming more and more perfect. The products that have been developed include: street lamps, lawn lamps, garden lamps, advertising light boxes, neon lights, landscape lights, signal lights, underwater lights, buried lights, etc. Its energy-saving and low-cost features are gradually recognized by consumers.
   According to industry insiders, the current application of solar LED lighting is still in the early stage of development, and the technology is in a stage of continuous maturity and improvement. The following areas are worthy of attention, mainly in places that the grid does not cover, such as mountains, remote villages, remote areas, etc. Solar LED lighting is almost the best choice there. In the field of park landscape lighting and auxiliary lighting, solar LED lighting also has a wide market.
   Wind and solar complementary LED lighting new market opportunities
   The application of “green energy†wind energy to photovoltaic LED lighting has formed a wind-solar complementary LED lighting system, which can supplement the shortage of solar power supply. This year, China's wind power generation technology has developed rapidly, and the wind and solar power generation system has been greatly improved, especially the breeze power generation technology. General Manager Yan Changyan pointed out that they can already generate electricity at a wind speed of 2 m / s.
   According to the calculation of relevant experts, the installation of an ordinary street lamp, about 15,000 yuan, plus electricity and maintenance costs, according to the ten-year life expectancy, an average of 10.07 yuan per day. If it is replaced by a wind and solar hybrid street lamp, the installation and maintenance costs are about 27,000 yuan, an average of 7 yuan per day, saving 3 yuan.
   Solar energy and wind energy are highly complementary in seasons and time. Through the battery, the lamps can basically achieve self-power supply. The wind-solar complementary street lighting system does not require transmission lines. Although the installation cost is higher than that of conventional street lamps, it is only a one-time investment and can be used once and for all.
The wind and solar complementary lighting system can be applied to road lighting, residential power supply, island power supply, urban and rural power supply, and the like. Especially in places where conventional power sources such as islands and remote mountainous areas cannot reach, their economic and social benefits are more obvious. Wind and solar hybrid power generation systems can be installed in more than 60% of China's regions.
