China, as a big producer of Led Lights, is actively arranging to promote low-carbon economy. A number of industrial policies have been introduced to support the growth and development of LED companies. Each industry capital is also very optimistic about the big LED cake market in China. Including OSRAM, General Electric, Lumileds, Infineon, Cree and other foreign lighting giants and domestic Sanan, Yinyu, Qinqin lighting industry leaders have actively laid out for China's future LED large-scale market early industrial layout.
Experts assert that in the future, the market share of LED lighting in China will be trillions of yuan. China has promoted the use of LED light sources in Chengcun Lighting, Chengcun Village Lighting, traffic lighting and home lighting projects as a special energy-saving policy for science and technology, which is listed as a “12th Five-Year Planâ€.
China will strongly support LED applications in fruits and vegetables lighting
LED applications are a major trend in the lighting of fruits and vegetables, and agricultural cultivation. China now strongly supports the use of artificial LED luminaires in the field of plant growth, so that ripe fruit and color look brighter. The most important LED lighting saves electricity compared to ordinary lighting.
LED energy-saving lamps are the fourth-generation lighting sources that are rapidly developing in China. LED lamps have many different characteristics from other electric light sources, which makes them the first choice for energy-saving and environmentally friendly light sources. In the past 10 years, the area of ​​horticultural facilities in China has developed rapidly. The light environment control technology for plant growth has attracted attention.
The horticultural light irradiation technology is mainly applied in two aspects: as a supplemental irradiation for photosynthesis of plants when the amount of sunshine is small or when the sunshine time is short; as an induced irradiation of the plant photoperiod and photomorphogenesis. LED has obvious advantages in both aspects.
LED lighting is expected to become the mainstream of plant lighting in the future. In order to save energy consumption, it is particularly urgent to find a lighting tool with both high luminous efficiency and long life. However, the fluorescent tubes commonly used today are linear light sources and cannot provide a large-area, uniform light source. Therefore, LED lighting is more suitable for uniform illumination of large areas of plants, he will become the new darling of plant lighting.
In traditional agricultural production, agricultural technology measures such as using ordinary electric light sources to supplement light and white light sources covering colored plastic films are generally used to change the light environment to regulate the growth and development of plants in the cultivation environment. However, these measures have different degrees of problems, such as the lack of analysis of specific spectral components resulting in impure light quality, inconsistent light intensity, close to or even lower than the light compensation points of plants, and low energy efficiency of irradiation light sources. LED can solve these problems, especially suitable for artificial light control plant cultivation environment.
At present, the main problems existing in the application of LED light sources in the field of plant growth are high cost and poor light penetration ability. Agricultural lighting products also have problems such as disordered products, non-standard production design, lack of unified product standards and quality management. Taking the plant lighting fixtures that are currently the largest in the market, as an example, LED lamp bead configurations based on red and blue light have been selected according to the needs of plants. However, there is a lack of scientifically uniform specifications for light quality adjustment and light intensity design. There is a lack of waterproof, electrical, and corrosion-resistant designs for the special high-temperature, high-humidity environments of plant lighting.
LED lighting will occupy a good position in the application of crop growth. OFweek semiconductor lighting network editor After studying the development trend of LED lighting applications in crops found that LED crop lighting market has been an upward trend, we expect 2012 or an important node, 2012 will become a watershed in the field of plant lighting development. At this stage, the LED luminous efficiency is continuously improving, and the research and development of LED lighting in crop lighting products is also greatly advanced, in order to eventually promote the development of LED lamps in crops.
LED can theoretically have a longer life, and is very good anti-vibration ability, so it is very suitable for use in the car; LED is also low voltage drive, used under the water is also very quiet, LED is another feature is energy saving, if used in the long Uninterrupted lighting and places where the color rendering index is not too demanding are all good candidates. However, the LED is not without its drawbacks. At this stage, the light fade of the LED is still too severe, the color rendering index is low, and the color tolerance is a fatal injury to household lamps.
According to the previous data of OFweek Semiconductor Lighting Network, the industry estimates that in 2008 LED will begin to replace the ordinary home lighting, by 2010 will be greatly improved universal, replacement will be enlarged. But at this moment, this estimate is still excessively "flexible." It is hard to predict that China's LED companies are somewhat "outside strong and weak." Now, no specific data indicate how many LED lighting companies are in the Chinese market. According to incomplete statistics in the industry, only the Pearl River Delta region has no less than 4,000, accounting for 70% of the world's total. LED varieties cover the home, business, electrician and other areas, mostly in the industry chain, and only 62 companies with LED chip production technology, even if there are large-scale packaging companies, not in the upstream of the industrial chain Several hundred outside. The distribution of LED profits in the industry chain, LED epitaxial wafers and chips account for about 70%, LED packaging accounts for about 10% to 20%, LED applications only account for 10% to 20%.
According to the "12th Five-Year Plan of Guangdong Province", emerging industries such as semiconductor lighting, energy saving and environmental protection are emerging industries for the development of Guangdong. In recent years, the LED lighting market in Guangdong has grown rapidly. It is expected that LED will replace incandescent fluorescent lamps in the next five years. The number will account for 50%. In the next decade, the data will increase to 80%. However, at present, the domestic LED market is very messy, bad brand, shoddy and other serious phenomena, China's LED lighting industry can still take a long way to go.
What is more noteworthy is that the development of the entire LED industry is still in a brewing period and layout period. There is still some distance from the actual output. The real lighting market needs to be further popularized. Now the market is still in the development phase. At this stage we To make more efforts in LED technology, we can deal with it when the market is approaching.
