What is the prospect of LED display in China? This is a colorful era. Life is more vivid. Public broadcasting satisfies everyone's enjoyment of sound in public places, but people who are more and more tasteful are more challenging to the image display industry. Because it is displayed in public places, the screen is required to be a sophomore, and the LCD screen is too small to be waterproof; on the one hand, the PDP should not be placed outdoors, on the other hand, the price is too high and the service life is short; therefore, the LED comes into being. It integrates the strengths of LCD and PDP, and is not afraid of wind and rain, environmental protection and energy saving.
According to the prediction of the professional consulting firm StrategiesUnlimited, the LED application market in China will reach 54 billion yuan in 2008, of which landscape lighting is the largest segment.
LED is a light source that is energy efficient, environmentally friendly, long lasting and versatile. According to the statistics of the Taiwan Industrial Research Institute (IEK), the global LED output value reached US$6.17 billion in 2006. The professional consulting firm StrategiesUnlimited predicts that the global high-brightness LED market will grow from US$4 billion in 2006 to US$9 billion in 2011, with an average compound annual growth rate of 16.7%. China has become an important low-end LED package in the world. Production base. In 2006, the output value of China's LED is 14 billion yuan. It is estimated that the application market will reach 54 billion yuan in 2008. By 2010, the scale of the domestic LED industry will exceed 100 billion yuan.
Starting from the "Eleventh Five-Year Plan", the Chinese government will promote the semiconductor lighting project as a major project. Most of the domestic enterprises are engaged in the packaging and application of LED downstream, and most of the chips, key equipment and technologies required are imported from abroad. The energy consumption of LEDs is only 10% of incandescent lamps and 50% of fluorescent lamps. The popularity of LEDs as a kind of illumination source will significantly reduce power consumption and reduce carbon dioxide emissions. LED production processes include single crystal growth and epitaxial growth, chip fabrication and packaging. The upstream single crystal and epitaxial growth are highly demanding in terms of technology and capital. The core issue of the LED industry is the breakthrough in materials technology, and its development history is a history of material development. Developed countries such as the United States, Europe and Japan actively support the development of the LED industry and introduce industrial support policies.
The landscape lighting market is mainly based on decorative lighting in public places such as streets and squares. Due to the low power consumption of LEDs, it has strong market competitiveness in the landscape lighting market with huge power consumption. In 2008, the domestic urban landscape lighting market will reach 20 billion yuan, which is the largest application area. For example, the famous Shanghai Oriental Pearl TV Tower has replaced all the 576 luminous points on the large and small spheres with LED lights, saving about 75% of the electricity consumption every night.
The biggest application for LEDs in the future is general lighting. Many countries are stepping up legislation to encourage the use of energy-efficient light sources. The European Union, Australia and the United States will ban incandescent bulbs in 2009, 2010 and 2020 respectively. Major international lighting manufacturers and third-party consulting agencies predict that LEDs will be widely used in indoor lighting by 2010. With LEDs accounting for 10% of the general lighting market, the potential size of the LED general lighting market will reach $25 billion. Taking road lighting as an example, the luminous efficiency of high-power LEDs has reached 60 lm/W, and energy-saving renovation of urban street lighting has become possible. At present, the relevant state departments have carried out the transformation test of more than 30,000 street lamps using LED light sources in Shanghai, and will be promoted nationwide after the completion of the test. According to the statistics of the national street lamp industry in 2006, there are more than 15 million street lamps in urban road lighting in China, and the growth rate in recent years is over 20%. According to this estimation, the annual market size of lighting street lamps in the country is not less than 5 billion yuan. The use of LEDs as a light source can save more than 2 billion kWh per year.
The LED is a light-emitting device (Light-Emitting-Diode) and is a light-emitting device made of a compound semiconductor material. The basic principle of the illuminating is to use the electrons and holes originally separated in the LED to convert the electric energy into light energy when the positive voltage is applied, and the energy is released in the form of light. Compared to incandescent and fluorescent lamps, LEDs are a light source that is energy efficient, environmentally friendly, long lasting and versatile. Through the transformation of the illuminating mode, the LED directly converts the electric energy into light energy, and the energy conversion efficiency is much higher than that of the incandescent lamp and the fluorescent lamp. In theory, the energy consumption of LED is only 10% of incandescent lamps and 50% of fluorescent lamps. The special survey of China Green Lighting Project Promotion Project Office shows that China's lighting electricity consumption is more than 300 billion degrees per year. If it is replaced by LED, it can save 1 The lighting power of the /3 is equivalent to the annual power generation of the Three Gorges Project with a total investment of more than 200 billion yuan. LEDs have a service life of up to 100,000 hours, 10 times that of fluorescent lamps and 100 times that of incandescent lamps. LED light source's miniaturization, fast response, rich color and digital control make it a huge application. The LED light source can be divided into visible light LED (wavelength 450~680nm) and invisible light (infrared light) LED. (wavelength 850~1550nm). Visible light LEDs can be further divided into high brightness and general brightness LEDs (with 1 cd as the boundary). Invisible (infrared) LEDs can be classified into short-wave infrared and long-wave infrared. LED products for lighting are usually manufactured by a blue LED chip through a packaging process in which a phosphor is added or a combination of a red LED chip, a blue LED chip, and a green LED chip.
Companies in Japan, the United States, and Europe have LED core technologies and patents, and are leading the way in technologies such as GaN-based blue LEDs and white LEDs. Taiwan and mainland enterprises started from the middle and downstream chips and packaging links in the industrial chain, and their production capacity gradually surpassed those of Europe and the United States. European and American manufacturers are gradually focusing on the research and development of upstream technologies, gaining the benefits of industrial development through patent licensing, and the production capacity is gradually shrinking. The relevant agencies estimate that the LED production value in Japan will reach US$3.3 billion by 2008, and the compound annual growth rate will be 4.8% from 2005 to 2008. In 2008, the LED output value in Taiwan will reach US$2.2 billion, with an average annual growth rate of 22.4 from 2005 to 2008. %. China's domestic market will maintain a growth rate of more than 30% in recent years. Among them, the growth rate of high-brightness LED devices exceeds 50%, and the growth rate of high-brightness chips exceeds 100%. In the future, Chinese enterprises may make breakthroughs in composite substrate and white light general lighting die technology, and reverse the unfavorable patent pattern. As the LED industry in South Korea, China's mainland and Taiwan gradually has certain innovation capabilities, technology leaders in the US, Europe and Japan will be more active in patent licensing.
Opportunities behind the opportunity, the 2008 Olympic Games, the 2010 Guangzhou Asian Games, the 2010 Shanghai World Expo, the 2011 Shenzhen Universiade, this one opportunity will bring explosive development to the LED industry. The Olympic effect affects not only sports, but also LEDs will definitely be with the Olympics!
