1.1, the purpose of the project and significance
In April this year was held in Shanghai the 4 th China international new light source and new energy lighting BBS, national semiconductor lighting engineering research and industry alliance international experts advisory panel members in the meeting ZhangGuoQi entitled 'semiconductor lighting technology and industry of new blueprint' speech report. His report aroused wide attention of industry and discussion. In his report points out that the semiconductor lighting industry chain is a DaoSanJiao shape, the bottom is triangle materials and equipment, and its economy is limited; The middle is lighting products; In the most at the top of the biggest, production value is lighting applications. According to the semiconductor industry for reference if, material equipment market scale is about $10 billion, semiconductor components market scale is about $25 billion, system and application products around $110 billion, while its impetus service industry to about $500 billion.
From the national semiconductor lighting engineering research and industry federation of the data we can also see that, 2009 domestic semiconductor lighting industry overall value of over one hundred million yuan, total application is more than 600 yuan. So, to semiconductor lighting industry for, if only do light sources and lamps and lanterns, profit space is limited. But extended to the system application and lighting solutions, will be added value, which is the development direction of future industry. On the other hand, long life is the advantage of LED products, but also LED the weakness of the industry. Because of its long life, imagine a LED light bulb life is ten years, consumers in these ten years might not have the necessary change, but for the markets will lose the consumption power.
Our research and development LED an intelligent lighting system will fully give play to the advantages of digital LED lighting, LED to push into the household market has a very important role. It is now the development of intelligent lighting system LED the best time, it will be LED the reform tide under a new wave of growth point for promoting the development of LED lighting, push on the national economic growth has important significance.
1.2, domestic and foreign technology development present situation and the trend
In recent years, with the development of science and technology and material life level enhances unceasingly. Household, hotel intelligent also unceasingly by people place praise highly. As intelligent parts of intelligent lighting system-more become modern decoration, decorate concerns. Thomas Edison invented electric light since since, causing boundless interests. Now people have not only used for electric light lighting, are more used to build sweet and romantic, colorful, beautiful, luxurious atmosphere. In the United States, for example, intelligent lighting in intelligent household industry accounted for the proportion of the first, even more than the security needs. Although the United States is the beginning of our study of the smart home, but the work of popular do best is in South Korea, this and South Korea advanced electronic technology is part of it, but also due to the policy of the government support, so the South Korea produced like samsung, LG, and other famous intelligent household brand.
Intelligent lighting industry since the 1990 s to enter the Chinese market since the consumer consciousness due to market, market environment, product prices, to popularize strength and so on various aspects of the reason there has been no big action and improvement. Foreign intelligent lighting products prices too high, and related products tend to just put the intelligent lighting as its intelligence product a subsystem to operation, positioning high-end, cause too high, as the s and s home appliance market. In addition, the domestic product promotion efficiency is far from enough. Because this is a brand new industry, different in fast moving consumer goods, channels of construction, idea formation, etc., are stepping stones across the river, so also dare not too much
effort and resources.
But with digital household concept of development and international brand and part of in such as: Dynalite, road and WIELAND, and so on, to promote the rapid growth of the industry, intelligent lighting as an important part of digital household was all intelligent manufacturer place seriously rise, intelligent lighting into primary rapid development phase.
1.3 project, the prospect of the industrialization of the analysis
The products in the industry, the development and application of the market is at a high growth stage. In the global energy supply nervous, environmental protection the grim situation of the objective condition, our country definitely put forward the strategy of energy conservation and emissions reduction goals. The LED lighting incandescent lamp, fluorescent lamp after as a new generation of 'revolutionary' light source, will greatly reduce the energy consumption in China. The industrial development and application of the market to achieve the strategic goal of energy saving and emission reduction of great significance. Semiconductor lighting development in our country specific goal is to 2015 years into the 30% average lighting market, substitute for imported 70% chip, industry scale up to 500 billion yuan, increased the employment of 500000 people; Achieve annual energy saving 140 billion degrees, 49 million tons of savings, reduce sulfur dioxide emissions of carbon dioxide, the gas, such as 140 million tons.
In the recently released 1025 planning, guangdong will be extended only 30 million indoor lighting lamps and lanterns, drive the indoor LED lighting the prevalence rate of more than 30%. Indoor lighting to demonstrate the application according to the scale to give 30% ~ 50% of the funds subsidies, and guide people buy replacement LED lighting lamps voluntarily. According to the average every lamp 200 yuan (including hardware, installation, commissioning cost) cost calculation, the future guangdong five years of LED the market capacity of intelligent control about 6 billion yuan, the scale of the industry of up to 60 billion yuan of above. So LED the prospect of the industrialization of the intelligent lighting system is very broad, has a very huge market space. the government following the LED chips again after a promoting economic development, promote the employment of the new growth point. the purpose of the project and significance In April this year was held in Shanghai the 4 th China international new light source and new energy lighting BBS, national semiconductor lighting engineering research and industry alliance international experts advisory panel members in the meeting ZhangGuoQi entitled 'semiconductor lighting technology and industry of new blueprint' speech report. His report aroused wide attention of industry and discussion. In his report points out that the LED strip led spot lights led flood light
2, the research development content, method, the technical route
2.1, the main research contents
1) LED digital dimmer.
Many times we only need a few light can meet the needs of the lighting, but the traditional light bulb just put out part of the light bulb to reach through the light effect, and are not real dimmer. Leds are semiconductor components, have natural digital dimmer advantage. Dimmer a variety of ways, in the light bulb is for a little time can use silicon controlled the number to achieve simple dimmer, but it must be of the number of light bulb is to realize the PWM digital light. We study the main LED digital light is the dimming PWM technology.
2) LED focus on digital management.
With LED lights number is more and more, to use the traditional switch control
