As we all know, compared with the European and American international markets, China's photovoltaic application market has not yet started, and is always in a tepid state. It is very difficult for the country to fulfil its promise of 20% renewable energy in 2020, but it is undoubtedly a shortcut to achieve its goal if it chooses to promote solar low-power LED street lights in large areas. With the promotion of the "Ten Cities and Ten Thousand Lamps" plan of the Ministry of Science and Technology, in the future, solar LED lights will be expected to be the first to open the domestic photovoltaic application market. As an important branch of solar LEDs, low-power LED lighting will also make a great contribution in the photovoltaic application market. Overcome the problem of low-power LED In the LED lighting industry, LED lighting is known as the "fourth generation lighting source" or "green light source". It is the "third lighting revolution" following "torch to oil lamp (candle light)", "oil lamp to incandescent lamp (fluorescent lamp, energy-saving lamp)", "incandescent lamp to LED lighting". For a long time, Europe, the United States, and Japan have monopolized the most critical white light, high-power LED lamp thermal balance, long-lasting and efficient phosphors and other technical cores in the LED industry. The domestic LED industry has been in a passive situation, and the requirements for independent innovation products are very urgent. In the LED industry, when the main direction of the focus is on the research and development of high-power technology, the Texas-based subsidiary of Texas Energy has taken the lead. It has chosen the main problem of the world's solar energy low-power LED lighting products and successfully mass-produced it. First in production. It is understood that the solar low-power LED (0.06W) product has a light efficiency conversion of more than 90%, a heat dissipation of less than 10%, no attenuation for 2000 hours, and a service life of more than 50000 hours, which maximizes the energy saving effect. According to the reporter, under the LED lighting industry subdivision, it is divided into high-power LED and low-power LED. Usually, more than 90% of the LED lighting currently used is an energy-saving lamp product that uses high power as a light source. The so-called high-power LED refers to the power of a single light-emitting diode is greater than or equal to 1W. Although high-power LED products are more energy-saving and environmentally friendly than conventional lighting products, they are still slightly inferior to low-power LED products, and many core technologies are in urgent need of breakthrough. It is understood that the conversion of high-power LED light efficiency is not high, only about 50% -60%, a lot of power is consumed on the radiator, which can be seen from the need to install a heat sink. In actual installation, high-power LED also has many problems to be solved. A large number of studies have proved that among LED lighting products, the highest light efficiency power of a single LED is about 0.06W, which is a small-power LED product. This worldwide problem has been overcome by a photovoltaic company in Texas. The German energy subsidiary not only owns the complete intellectual property rights of low-power LEDs, but also technically solves key issues such as heat dissipation and light decay. It has become the very few in the world that has low-power LED lighting. Manufacturer of patented products. Now, the company's product technology has been developed to the eighth generation. According to Liang Baoqiang, the research and development director of Deyuan Group: "The company's ninth and tenth generation products have also been successfully developed, and the products are in the reserve stage. In addition, the company's solar and wind power generation, solar water, solar cars and other products There are also new research results in application. " Economic value of low power LED All along, developed countries have gradually increased their support for the LED lighting industry. In 1998, Japan spawned 6 billion yen to start the "21st Century Light Plan"; the United States has invested 500 million US dollars since 2000 to implement the "National Semiconductor Lighting Plan"; in the same year, the European Union also announced the launch of the "Rainbow Plan". Although China started earlier in the LED industry, the government did not support it enough. It was not until 2009 when the Ministry of Science and Technology's "Ten Cities and Ten Thousand LED Projects" document was launched that the domestic LED industry ushered in a large development, and various regions competed to launch LED projects. As the heat of the domestic market has increased, the LED industry has once fallen into the dilemma of flying in concepts, flourishing, and scarce innovations. Some of the installed high-power LED lights are not as satisfactory in the demonstration project. Problems such as night light off, short life, insufficient brightness, and difficult maintenance have appeared. The solar lights that were originally installed were later changed to thermal power to illuminate, highlighting the shortcomings of energy saving and saving money, seriously damaging the confidence of installing LED street lights everywhere, and hindering the healthy and rapid development of the LED lighting industry. Fortunately, the country has always promoted the development of the LED industry as a strategic development direction. On May 19, the Ministry of Science and Technology again issued the second batch of pilot demonstration projects to continue to clarify the strategic direction of the LED industry, injecting new impetus to the development of the LED industry, and the future domestic market has broad prospects. According to reporters, the pilot project of "Ten Cities and Ten Thousand Lamps" mainly involves the public lighting facilities in various provinces and cities, that is, the replacement of street lamps, and the market space is huge. In 2010 alone, more than 220,000 LED lights were installed nationwide. Due to the pressure of energy saving and emission reduction targets in 2020, industry experts predict that the LED industry will still maintain rapid development. Today, the obstacles to the development of the LED industry are mainly concentrated in the higher initial installation costs. In fact, the initial installation price of LED is higher than that of traditional energy lamps, but the economic benefits are very considerable in the long run. In this regard, Bai Yuxiang, the sales director of Deyuan Group, calculated an account for the reporter. Bai Yuxiang introduced that compared with the traditional high-pressure sodium lamp. If the same brightness is reached, the high-pressure sodium lamp needs 200 watts to calculate, and the solar low-power LED lamp only needs 20 watts. According to the lighting demand of 10 hours per day and industrial electricity consumption of 1 yuan, the annual electricity cost of each high-pressure sodium lamp is 200W * 10 hours * 365 Day * 1 yuan = 730 yuan. The solar low-power LED lighting does not require thermal power, and each can save electricity costs up to 730 yuan per year. This does not include the cost of installing cables and other equipment in the initial stage of installing high-pressure sodium lamps, and long-term manual maintenance. Solar low-power LEDs have no cost of laying cables, no manual maintenance, and no electricity. "The initial installation cost of solar low-power LEDs is higher than that of ordinary high-pressure sodium lamps, but all the investment can be recovered within 2-3 years." Bai Yuxiang said. Compared with high-power LEDs, low-power LEDs also have advantages. According to Hao Huiqing, Engineering Director of Deyuan Group, "The cost of solar low-power LEDs is only 2/3 of that of high-power LEDs. This is mainly because the high-power LEDs require a large amount of power consumption, and the power of the solar panels matching them increases. Larger, the capacity of the battery also needs to be increased, thereby increasing the cost of the entire control system. " In addition, in terms of energy saving, a 20-watt 6-meter high low-power LED lamp is used as the standard. The brightness is equivalent to that of an incandescent lamp of 400 watts. If you want to achieve the same brightness, high-power LEDs require 40 watts. LED saves energy more than twice. Not only that, the performance of small power is also remarkable, and it still maintains a record of zero maintenance in installation engineering products. Foreign customers want to compete for agency rights At the Texas Solar Energy Conference, the appearance of solar low-power LED products attracted the attention of foreign companies. Xue Yuanzhang, chairman of Deyuan Group, said: "Now, the company receives several customers from all over the world every day. Some customers immediately asked us to give them exclusive agency rights after inspecting the products." Good products need good markets. Cui Lei, Director of Operations of Deyuan Group, has already planned how to develop the future market for products. He said: "The awareness of energy conservation and environmental protection abroad is generally strong, and the recognition of energy conservation and environmental protection products is also very high. In the future, the company will focus on the foreign market and plan to list in the United States within the next two years. At present, there are already Germany , Guests from the Netherlands, France, Canada, the United States, Japan, the Middle East, Sweden, South Africa and Angola have come to the company to discuss business. " On the day of the interview, Deyuan Group received a notice from the Texas government, requesting the company to receive a visit from Malaysian Datuk at 8.30pm. Visiting the site, Assistant Datuk said that Malansia is very optimistic about this solar low-power LED product and plans to import large-scale or invite enterprises to invest in and build factories in Malansia. There is great hope for future cooperation between the two parties. At the time when foreign customers swarmed, the domestic market also showed exceptional activity. At present, the company has received warm invitations from the governments of Nanning, Guangxi, Xiamen, Fujian, and Inner Mongolia, hoping that Deyuan can develop locally. On May 21, the company has reached a cooperation intention with Tongliao City, Inner Mongolia to radiate market demand in the three eastern provinces. What is certain is that under the consensus of energy saving and emission reduction in the world, solar low-power LED will set off a new revolution with its remarkable "energy saving and emission reduction" effect.
