LED brings the city's "light revolution" into the main force
"LED" is not really a new term, but it has been a bit far from everyday life. It is a simple "light-emitting diode (L igh tin g em ittin g D iod e)" in the physics world. It uses solid semiconductor chips to emit energy and can directly emit red, yellow, blue, green, cyan, orange, purple, white and other colors. Light.
Today, however, in the streets and lanes, such a charity donation box may have attracted you to show your love: it can broadcast public service advertisements and send a thank-you to the donors; in home accessories stores, such alternative photo frames may be particularly addictive: it can Continue to produce a soft backlight to make the photo crystal-like... After the semiconductor technology revolution led to the microelectronics industry revolution, it will brew a new "light revolution": LED is changing the city in a quiet and silent way. And life.
The main force of the future in the field of lighting
Many people may be unbelievable. In addition to the improvement of the filament, the lighting fixtures we use today are not fundamentally different from the Edison era. With the upgrading of the indoor and outdoor decoration industry, indoor nightlights, lawn lights of public green spaces, and building landscape lights have placed high demands on cost reduction and energy saving, and existing lighting equipment has entered a “bottleneck periodâ€.
Tsinghua Science and Technology Park Optoelectronics Co., Ltd. has the first domestic LED production line with a mass production of more than 60 lumens per watt. The company's technical staff said that as a new type of semiconductor light source, LED's most significant advantages are energy saving, environmental protection and longevity. LED energy consumption is only 10% of incandescent lamps and 50% of fluorescent lamps; it is solid-packed, has a solid structure and can last up to 100,000 hours, 10 times that of fluorescent lamps and 100 times that of incandescent lamps; it does not require glass vacuum packaging. No toxic gas and mercury pollution. Chen Lianghui, an academician of the Chinese Academy of Engineering, calculated an account: 15 years to invest 5 billion to 10 billion yuan to develop the industry, equivalent to rebuilding a "Green Three Gorges Project" with only 5% of the Three Gorges Project.
In recent years, the world's three major lighting industry giants - General Electric, Philips and Osram have set up semiconductor lighting companies, developed countries have even started national projects, hoping to seize the commanding heights of emerging industries. The US Department of Energy has set up a national research project for semiconductor lighting. It is planned that more than half of incandescent lamps and fluorescent lamps will be replaced by 2010. In 2025, the US lighting power consumption will be reduced by half compared with the current one--this must be achieved by the current $50 billion annual light source industry. To support; Japan plans to save the equivalent of one or two nuclear power plants through semiconductor lamps.
In China, the Chinese Academy of Sciences has carried out relevant research as early as the 1960s, but the pace of industrial advancement has lagged behind. The industry analysts believe that the gap between China's LED technology and the international advanced level is not large, as long as the overall promotion is appropriate, a solid-state lighting industry with core competitiveness is forming.
However, the popularity of LED lighting in the LED industry still needs a “thrilling leapâ€: its photoelectric conversion efficiency is low, but the price is high, even if developed countries still need to overcome the cost. Yu Wei, a professor at East China University of Science and Technology who specializes in LED light sources, pointed out: "The LEDs are slower in heat dissipation than other light sources, and heat transfer is three orders of magnitude lower than that of metal materials. It is currently difficult to handle square lighting, building facades, and park landscapes. Light and other glare lighting tasks. If some buildings with long history and serious style adopt LED light source, they will not only lose the original charm, but also bring new light pollution.†He pointed out that the absolute advantage of LED lighting is in the small environment. And local lighting. Therefore, when considering entering the industry, enterprises should measure their own conditions and clarify the direction of the market. There is no need for a glimpse.
New highlights of outdoor advertising
Compared with traditional media such as radio, television, newspapers and periodicals, the unique advantages of outdoor media – high arrival rate and low cost of thousands of people are increasingly prominent. In addition to focusing on the attention that outdoor advertising can attract, more and more mature customers pay more attention to whether they can reflect professional quality and thus enhance brand value. Therefore, traditional outdoor media such as street signs, light boxes, neon lights and other single, static expressions can no longer meet the needs of customers and audiences. The large-scale LED display, which combines technology and media, has begun to attract attention in the industry.
After the last 10 years of development in the last century, today's LED displays not only have high brightness, large contrast, bright colors, but also dynamic display of pictures and text. It actively emits light and has high resolution at a long distance. Even if it is 100 meters away, the visual effect is no different from watching TV at home. It is especially suitable for public places and traffic routes with dense crowds.
According to experts' predictions, the demand for various types of LED displays in the world will reach billions of dollars per year in the next few years, and it is increasing year by year. In China, according to the statistics of the National LED Optoelectronics Industry Association LED Display Branch, the current LED display industry sales of about 4 billion yuan. With the approaching of the 2008 Beijing Olympic Games and the 2010 Shanghai World Expo, as well as the country's unprecedented attention to environmental issues, all kinds of positive factors will stimulate LED outdoor advertising into a significant growth period. Recently, the famous domestic advertising company Focus Media, Oriental Pearl Mobile and so on have entered the outdoor LED market is a testimony.
The industry generally believes that the technical level of China's LED display industry is relatively advanced, but the level of technology is relatively backward. It is obviously inferior to the international advanced level in terms of product standardization, overall system design, reliability, testing and testing methods, and hinders customers to some extent. Create a brand image. It is even more difficult to achieve perfect matching in the follow-up links such as media channels and operational standards.
Tulip Media is a local company that overcomes these weaknesses and successfully attracts international capital. It signed an agreement with Credit Suisse recently and received $30 million in financing. In addition to the previous financing from the world's second largest outdoor advertising company, Deco and the famous American Huaping Fund, its LED business has become the largest single media project in the domestic media industry.
According to a spokesperson for the Tulip Media Company, from the beginning of entering the LED advertising market, the company has paid special attention to the integration of international standards from all aspects of business philosophy to site selection standards. “All of our LED large screens are only built on the landmark buildings in the CBD of the economically developed cities. Not only have they contributed to the spread of more than 500 international and domestic first-line brand customers, but they have also added lustre to their buildings, highlighting them. In addition, the company has been actively involved in social welfare activities and events, such as Shanghai Formula 1 racing car, 'Master Cup' tennis tournament, etc. These innovative business models and values ​​are important reasons for the recognition of us in the international capital market. â€
Local industry: seeking opportunities in the challenge
For a long time, the domestic LED industry was in an awkward position to buy devices, buy chips, and buy epitaxial films. But today, China has realized the independent production of epitaxial wafers and chips. Peking University, Tsinghua University, Institute of Semiconductors of the Chinese Academy of Sciences, and 13 institutes of CLP have been engaged in related research, and more than 4,000 enterprises have basically covered the upstream and downstream of the industrial chain. The Yangtze River Delta, the Pearl River Delta, the Triangle and the North have become the gathering place for the development of China's LED industry.
At the policy level, the Ministry of Science and Technology has included the “National Semiconductor Lighting Project†in the “Eleventh Five-Year†Science and Technology Development Plan as a key task, and at the same time, based on the development status of China's semiconductor lighting, formulated industrial development in line with its own development. Planning and technology development roadmap.
The upstream of the industry is the current weakness of China. This stage is technical and capital intensive, with high investment and difficult process. At present, although there are many units involved in this link, R&D is mostly concentrated in universities and research institutes, and production is in various enterprises. In general, resources are scattered, and there is a lack of rapid conversion mechanism for industrialization of R&D results. Therefore, in the future, enterprises and scientific research institutions should change their concepts and establish communication channels for timely authorization and transfer, so that research results can be effectively integrated.
In the downstream of the industry, on the one hand, due to the moderate investment intensity of equipment, the entry threshold is not high. On the other hand, the huge domestic application demand has begun to appear, which has attracted a large number of individuals and private enterprises, especially in the Pearl River Delta region. However, the downstream industry still lacks uniform industry standards, and there are relatively few small-scale enterprises. It should be guarded against the emergence of low-quality, low-price and vicious competition.
From the past practice, China's domestic scale industry development has been bumpy. The most typical example is the integrated circuit and LCD panel industry. The technology is complicated, the investment is big, and the foundation is weak. So far, no solution has been found. And can the LED industry stand out and drive the improvement of related industries? At present, it seems that its key words such as core intellectual property rights, market support, integration of industry, education and research are not mature enough but the prospects are promising. The most urgent thing is whether enterprises can foster strengths and avoid weaknesses and seize opportunities in challenges. Going home.
