In the country to promote the upgrading of culture, education new industrial growth point of the strategic task of guiding the optimization of the industrial structure, LED has become the focus of the development of the local government, Dongguan, Huizhou, Foshan, Shenzhen, Dalian, Nanchang, Xiamen and other local governments have formulated the development strategy of industry compliance plan, set off a wave of domestic LED investment boom. As nearly half of the country occupied the domestic LED of the total output value of Guangdong in the May release of "" several opinions on accelerating the transformation of economic development mode in the semiconductor lighting industry (LED) of the three strategic emerging industry listed in Guangdong for the recent focus on charge. LED industry has formed a situation in Guangdong. Shenzhen, Dongguan and Foshan have LED industry as the pillar industry development . LED industry has been showing full flowering potential.
The rapid rise of domestic LED enterprises and the rapid expansion of production capacity, market expansion for LED. From the domestic LED industry leading enterprises to expand production capacity of three optical Silan to befuddles BDO Runda, LED industry boom almost swept the entire industry, the overall level of domestic LED products is not high, domestic enterprises are generally small scale, weak strength, product quality is relatively low, LED fierce market competition, the relevant manufacturers for the price war at the same time, LED industry also appeared disorderly investment, vicious competition phenomenon. From the current domestic market dynamics and LED industrial structure distribution, there have been serious duplication of investment problems.
In addition, some local governments in the economic development in the local market to open to local enterprises, or by investment in the market the way to lock the local market, local protectionism is on the rise trend. If you don't break the local administrative barriers, will inevitably bring about the convergence of regional industrial projects between the direct increase industry bubble, hinder the development of regional integration process. To highlight the different characteristics of different regions, to avoid repeated construction for short-term interests of simple , vicious competition in the future.
In addition, Chinese LED lighting has a series of other problems, such as China there is no national standard LED lamp, only some local standards; Chinese LED lamp innovation design capacity is obviously insufficient. To solve these problems, in order to make a more healthy development of LED industry, LED products in order to better meet the needs of the public. Is the market leading LED lighting industry can long-term healthy development of the based foundation, the government in policies and regulations, investment in research and development, application demonstration and standard aspects to guide and support the whole country, the overall planning, in order to guide the sustainable and healthy development of LED industry.
LED and LED visible light communication technology
Since the high power LED will become the next generation of solid-state lighting in the main, the electronics industry has emerged more bold new thinking. It is to abandon the RF bandwidth crowded, to quickly switch to LED mode to transmit the eye is difficult to distinguish according to the number of , this way is called the LED visible light communication (VLC . Through the advanced technical support, each new LED lamps can be wired access backbone network, the wireless communication between different devices can be omnipresent, and will not increase the negative existing RF bandwidth. The LED visible light communication technology using white LED , because white LED features fast response, can serve as a base for visible light communication technology. LED visible light transmission technology is the use of fluorescent lamp or white LED lighting equipment, a naked eye can not detect high-speed light flashing signal in wireless mode to transmit data. The visible light is because the wavelength range, through the design of the visible light signal through different wavelength transmission. The researchers also tested the different wavelength, use different colors white, developing the content of encoding multiple data streams. (SSL)
The advantages of LED visible light communication technology, in general can avoid electromagnetic wave WLAN or high frequency wireless transmission, interference effects on the human body and the surrounding electronic equipment, and can replace the wireless base station , also has the characteristics of high safety. At present, many industry standards organizations, or government funded programs are started to develop LED visible light communication, its prospects are very promising. After all, only the traditional lighting market size will reach trillions of dollars in the future, the transition to solid state lighting market, the business is very considerable.
