The development of the optoelectronic industry is the active and in-depth implementation of the scientific development concept, the transformation of economic development mode, the promotion of industrial structure optimization and upgrading, the enhancement of industrial international competitiveness, and the integration of the actual service industry with the development of the modern service industry and the advanced manufacturing industry. To build eight important carriers with strong driving force, optimize the industrial development environment, and establish a modern industrial system that is not only in line with the world but also has Guangdong characteristics, and strives to be an important direction for the development of the modern industry in the country.
As the emerging sunrise industry with the most promising prospects in the 21st century, optoelectronics industry, optoelectronic display, semiconductor lighting, optoelectronic information storage, optoelectronic military, optoelectronic energy and other fields have been widely used in Guangdong. On this basis, Guangdong will focus on the development of optoelectronics industry based on LED, flat panel display and solar energy industry during the 11th Five-Year Plan period.
Develop LED industry to help save the society
The proposal of the national scientific development concept is a powerful impetus to the industry. The country's proposal to build a conservation-oriented society and achieve green GDP is an important part of the national scientific development concept, which has become a powerful driving force for the rapid development of the energy-saving industry. With the implementation of the energy conservation policy proposed in the 11th Five-Year Plan, industrial guidance policies at all levels have been introduced one after another. The LED lighting industry with long-life, energy-saving, safety, and environmental protection will have a bright future.
According to statistics, current lighting power accounts for about 12%-20% of total electricity consumption. According to conservative estimates, China's total power generation will reach 300 billion kWh in 2010, and lighting power consumption will be about 360 billion kWh. If it can save half of the lighting power is 180 billion kWh, equivalent to the annual power generation of the two Three Gorges power stations. Under the global tide of energy conservation and environmental protection, lighting energy conservation has naturally become the focus of attention, and energy saving is the biggest advantage of LED. The LED uses a low-voltage power supply, which has high energy efficiency, low power consumption and energy saving. The third-generation semiconductor material, gallium nitride, is used as the LED illumination source, and consumes only 1/10 of the ordinary incandescent lamp at the same brightness.
As a new lighting technology, LEDs (light-emitting diodes) are light-emitting devices that use semiconductor chips as luminescent materials to directly convert electrical energy into light energy. Unlike the tri-color toner illumination of incandescent filaments and energy-saving lamps, LEDs use electric field illumination. Since the LED is an all-solid illuminant, it can withstand high-strength mechanical shock and vibration, is not easily broken, and is easy to recycle. Moreover, the LED light source itself does not contain harmful substances such as mercury and lead, and has no infrared and ultraviolet pollution, and will not cause pollution to the outside in production and use, so the environmental protection effect of the LED is also very obvious. The LED light source uses a low-voltage power supply, which is easy to use with solar cells and is more environmentally friendly. At the same time, as a low-voltage lamp, safety is also a prominent advantage of LED.
With the continuous development and advancement of LED product technology, LED applications have expanded from earlier display, mobile phone and LCD background light sources to more profitable applications such as general lighting, theater lighting, and automotive heads. Lights, brake lights and traffic lights, and even on the most popular HD LCD TVs, LEDs are expected to replace the CCFL backlights that have been used. With the development of the urban construction of the 2008 Beijing Olympic Games and the 2010 Shanghai World Expo, the demand for LEDs in urban landscape lighting will further increase.
China LED market application structure
As an important base for the production of electronic products in China, LED applications in Guangdong also occupy an important position in the national market. Especially the application of LED interior decoration is particularly prominent. For example, in Zhongshan Town, the annual output of lighting products accounts for almost all national lighting. 60% of the total market, which greatly spurred the rapid growth of LED application market in the field of lighting.
