In 2006, the output value of China's LED was 14 billion yuan. In 2008, the application market scale reached 54 billion yuan. It is estimated that by 2010, the scale of the domestic LED industry will exceed 100 billion yuan. Among them, the market size of lighting lamps is 25.4 billion US dollars, and the market size of lighting equipment/devices is 106.6 billion US dollars. Commercial lighting accounts for 43% of the total lighting market in the world, with the highest proportion. The total electricity consumption in the retail, office, warehouse, education, health care and other applications accounts for 70% of the total commercial lighting market.
LED is a kind of luminescent semiconductor component and is recognized as one of the most promising high-tech products in the 21st century. It is also a product that we urgently need to pay attention to in 2009. While LED has triggered the lighting revolution, it has also made significant contributions to promoting energy conservation, emission reduction and environmental protection. With the government's vigorous promotion and global industrial ladder transfer, China's LED will become the most attractive cake on the market in the future.
Review of the development of global LED lighting
When there is a LED in the market, the light source is very low. At that time, the main luminescent material used by engineers was GaAsP. The driving current was 20 mA, and only red light was emitted, and the luminous efficiency was only 0.1 lm/W, so the brightness could only be To meet the instructions on some instruments and electrical appliances, it has not been widely used and noted.
Through continuous innovation and development of technology, in the following decades, some new luminescent materials were gradually introduced into LEDs, and LEDs gradually began to show strong development potential. In the mid-1970s, by introducing the elements In and N, the LED can emit green light with a wavelength of 555 nm, yellow light with a wavelength of 590 nm, and orange light with a wavelength of 610 nm. The colorful light of the LED illumination is also illuminated. people's lives. At the same time, the luminous efficiency of LED lighting has also increased to 1 lumen / watt. According to the development speed of China's photo materials science in recent years, LEDs with luminous efficiency of 200 lumens per watt will also be available in a relatively fast time.
With the success of the 2008 Beijing Olympic Games, the high-tech application of LED lighting has been mentioned as a new ladder, and the application of complex and varied changes has added a lot of color to the whole world. The increasingly popular LED lighting and signal display market in 2009 has become even more incredible, and has added more diverse elements to enrich people's lives. This includes torches, building lighting, road lighting, traffic lights, road indications, and signal displays. In 2009, the entire LED market will show steady, double-digit high growth, higher than other LED market segments, such as automotive and consumer goods market IMS senior forecast, LED lighting and display components will account for 30 of the entire LED market in 2013. % will face tremendous development opportunities.
The development of China's LED lighting industry
The most critical reason for LEDs to have such a broad business prospect is the unique features of their high energy efficiency. As the third-generation semiconductor lighting material, the life of LED is 100 times that of ordinary incandescent lamps, energy consumption is much smaller than incandescent lamps, and the replacement cost is lower. It has the advantages of volume filial safety, pollution-free, maintenance-free, fast response, etc. Subsidiary advantages.
In recent years, modular LED displays have been widely used in the world. Their high display brightness and flexible matching method have been recognized by most people and have become the main varieties of outdoor display devices. And it has been widely used in activities, performances, exhibitions and other industries. The dream five rings and the water cube at the opening ceremony of the Beijing Olympic Games gave the world a good memory, which was displayed on a huge 1564 square meter large LED display. It is by far the largest single full color screen in the world. LED is such a hero to praise the world!
It is understood that the 2010 Shanghai World Expo will be the center of a new round of urban infrastructure and sports venue construction and renewal. Because they have promoted the LED-dominant as a new green light source in engineering implementation, this will be the step-by-step transfer of LED lighting to achieve leap-forward development.
In addition, the Shanghai Municipal Government has also formulated relevant policies and measures to promote the development and application of the LED lighting industry. LED lighting is listed as a special technology fair, focusing on the focus and vigorously supporting the wide application of LED lighting at the World Expo. The 2010 World Expo will be a major turning point in China's LED lighting industry.
The promotion of LED lighting in China is quite urgent and the market potential is huge. In view of the accelerated development of the city, the LED lighting industry is bound to have much to offer.
