Especially the complex networking technology, wireless sensor network technology and smart grid and other energy saving control system of integrated application-aware practice, making for intelligent energy-saving LED lighting control systems for smart buildings, smart appliances and traffic lighting.8 percent for the landscape lighting of the LED market compound annual growth rate of 21. Epoxy resin is to led filament bulb dimmable protect the LED's internal structure, to add different materials or shapes can change the shape of the light-emitting diode LED color, brightness and angle. LED chip is a major component materials, semiconductor chip consists of two parts: one is P-type semiconductor, the hole in it dominates; the other is N-type semiconductor, here is mainly electronic. Gold wire used to connect the LED chip pad (PAD) and the stent and allow it to turn; silver conductive glue chip and play a fixed role; stent by stent material formed after plating." Until July 2008, National Semiconductor Lighting Project Coordination Leading Group of the Sixth Working Conference the successful conclusion of all illustrates the semiconductor lighting technology research and application for the further implementation of the "Long-term Scientific and Technological Development" is of great significance, and lighting technology for clear direction.

October 12, 2009, the National Development and Reform Commission, Ministry of Science, Ministry of Industry and Information Technology, developed jointly by six ministries, "semiconductor lighting energy industry," and proposed "to 2015, average annual output value of semiconductor lighting energy industry growth rate 30% market share increase year by year, functional lighting up about 20%, landscape decoration market share of 70% or more "and other goals.

. LED's core structure is a semiconductor chip, the chip attached to one end bracket, one end of the cathode, the other end connected to the mains positive, and the entire chip with epoxy resin (plastic) package together.7 percent.

When these two semiconductors, when connected between them to form a "P - N junction. Particles from the LED lighting principles and characteristics, combining engineering expertise to discuss the LED lighting system design process and considerations are given to solve the corresponding issues.
With the led technology, networking technology and wireless communication technology, LED lighting, its particle pollution, long life, good point, and easy to transport and so gradually developed to commercial stage. Expected to 2013, China's LED lighting market, LED street lamp market size used in the average annual compound growth rate of 38.
A, LED lighting principle and characteristics of particles

LED light-emitting diode, a solid-state semiconductor devices, which can be converted directly into electricity to light. China 2008 LED street number 600 000 2011, will rapidly grow to 5 million, the annual compound growth rate of 102.7%.

As China's semiconductor lighting technology for the gradual attention in June 2003 national semiconductor lighting industrial project was officially launched in December 2007, Ministry of Science and the State Administration of Foreign Experts Affairs jointly approved 33 units to establish a national International Joint Research Centre, Institute of Semiconductors become one of the "national semiconductor lighting the International Joint Research Centre." When the current through the wire act on the chip, electronics will be pushed to the P zone, with the P zone electron hole recombination, and then will be issued in the form of photon energy and wavelength of light is the light color Jump Start is by the formation of "P - N junction" material decision.
LED structure shown in Figure 1, the basic structure, including: epoxy, chips, gold, silver and plastic stent. Since the development of China's LED industry is not balanced and some related engineering personnel LED lack of expertise, resulting in the blind use of LED lighting and LED lighting system design particles irrational phenomenon. Beijing 2008 Olympic Games and 2010 Shanghai World Expo will have the development of LED industry made a perfect interpretation, as shown in Figure 1, shown in Figure 2
