The output value of LED in the first half of the year increased by 25 year on year. The scale of LED industry continued to grow. The annual output value in 2012 was 192 billion yuan, up from 2011. In the first half of 2013, the overall recovery trend of the industry was obvious, with the overall output value increasing by year on year and the output of LED devices increasing by year on year. 7/. The performance of listed companies is even more eye-catching. After a brief decline in operating income in the first half of 2012, it began to rise by more than 25 from the third quarter of 2012. In the first quarter of 2013, the operating income of 19 listed companies increased by 21. The competition in the lighting industry is getting more and more fierce, and the enterprises are very scattered. Judging from the statistical concentration of enterprises, it only accounts for 15%. Since 2012, the price has been lowered, from 2013 4- In the first quarter of June, the average price fell by about 25. From the perspective of investment, it gradually tends to be rational. From July 2012 to June 2013, the clear investment amount of the project reached 14. 6 billion yuan. In the first half of 2013, LED industry investment increased by 57. From the perspective of investment, from the middle and upper reaches to the downstream and supporting. Downstream applications account for more than 40, and industrial support is more than 30. The key application fields of LED in the future are commercial, industrial and public lighting. From the industrial lighting itself, the potential is very large. First of all, the proportion of industrial lighting electricity is relatively large, about 28, and the penetration rate of industrial lighting is gradually increasing. At present, the product structure is still dominated by substitute products. Secondly, the payback period of industrial lighting investment is relatively short, generally 2-3 years. At present, the market penetration rate of LED lighting products is relatively low, only 3. 5% in 2012. LED lighting market penetration or will speed up, is expected to break through 30 in 2015. The initial demonstration project has driven the transformation of the municipal system into a major market for lighting applications, mainly concentrated in public lighting fields such as roads, tunnels, squares, and subway lighting. It will take time for LED to enter home lighting. Intelligence is a good application mode of LED. LED is characterized by low power consumption, long service life, rich colors, vibration resistance, strong controllability, etc. The future trend will be modular power supply. During the 12th Five-Year Plan period, the main battlefield of energy conservation and emission reduction will shift from industrial energy conservation to building energy conservation; Building public area lighting is a large market with potential for efficient power saving technology. Intelligent LED lighting technology provides a good means for market-oriented operation of lighting energy conservation in public areas of buildings. Modularization is the only way for LED enterprises to develop, and intelligence is the best application mode of LED light sources. Not only for light sources, other components of semiconductor lighting products, such as power supplies, detectors and controllers of dimmable lamps, should also be modular, normalized and socialized. The Hebei Provincial Department of Education uses a total of 661 LED intelligent lamps, replacing the original straight fluorescent lamps, grid lamps, etc. Through the whole process of tracking and monitoring by Hebei Energy conservation monitoring and monitoring center, the power saving rate can reach 90. 3, annual electricity saving 12. 760 thousand KWh, annual electricity savings of 10. 850 thousand yuan, equivalent to an annual saving of 42. 5 tons, reducing carbon dioxide emissions by 127. 3 tons, the project investment payback period is 2 years. Under the guidance of the concept of on-demand lighting, using this feature and combining various technical means to realize intelligent LED lighting, it has been popularized and applied in public building areas such as underground parking lots, walking ladders, corridors, elevator antecedents, public toilets, etc. It has excellent power saving effect and strong competitiveness.
