In the normal operation of the program, P1 port of the 8 LED lights as a single light, left shift 8 times, and then a single light to the right 7 times, so cycle; interrupt (press button), then P1 mouth 8
According to the world market research agency report pointed out that in 2008 the global LED market demand of about 100 billion, sales value reached $7 billion 500 million; expected in 2009 due to the LED backlight module in the wide penetration of products LCD TV, notebook computer and mobile phone and other Chinese market driven large scale people Zhe LED lighting and outdoor advertising applications, the global output will LED a substantial increase to a record high of $8 billion 677 million record. By 2012, the global LED output value will exceed 12 billion US dollars, and by 2015, our country will be around 500 billion of the major strategic products, such as backlight, lighting and automobiles. The LED industry has come to the fore and has become an emerging industry in the world.
LED industry is an important part of modern electronic information industry system, has an important role in boosting the automotive electronics, raw materials, consumer electronics, optoelectronics industry, is the great development potential of the emerging industries and strategic growth. The plan for the adjustment and revitalization of the electronic information industry and the outline of the reform and development plan for the Pearl River Delta (2008-2020 years) issued by the State Council have explicitly included the semiconductor lighting in the key areas of development. As Chinese lighting appliances brand base in Huizhou, the development of the LED industry, to speed up the construction of the national industrial base, promote the upgrading of industrial structure in our city, enhance the competitiveness of our city, has very important significance to enhance the economic development potential.
In recent years, it has been widely used in display, traffic lights, landscape lighting and interior decoration, and gradually began to be used in LCD, backlight, automotive light sources and other fields. According to statistics, in 2008 the output value of applied products has exceeded 45 billion. Beijing Olympic Games venues large-scale application of LED products, fully demonstrates the LED into commercial applications of replacement technology, products are gradually mature, the industry is now in a high growth period. LED is the next generation of lighting product upgrading, energy saving, environmental protection, covering electronics, equipment manufacturing and other fields, has an important role in boosting the automotive electronics, raw materials, consumer electronics, optoelectronics industry, is a new industry with great potential for development. At present, the main application areas of LED are LED landscape lighting, LED display, LED street lamp, LED backlight, LED decorative lighting and so on. With the large-scale application of LED products, consumer electronics and lighting products have entered a new round of upgrading, which can expand domestic demand and stimulate rapid economic growth.
At present, the United States, Japan, the European Union has always been in the upstream of the LED substrate, epitaxial wafer, chip production holds the patent leading core technology, while the Taiwan area China by tracking technology and scale of development has become an important global LED production base, therefore, the formation of the industrial pattern in the United States, Asia and Europe as the leading and showing to a situation of tripartite confrontation, Japan and the United States, Germany as the industry leader, Chinese Taiwan, followed by South Korea, China echelon distribution of mainland China and Malaysia and other countries and regions actively follow up.
