In todays world, lighting is the most basic requirement. According to the data, lighting energy consumption accounts for about 20% of Chinas electricity consumption. In recent years, Chinas energy consumption and environment have deteriorated seriously. Therefore, China has put forward a sustainable way of energy conservation and emission reduction, and developed clean and environmentally friendly energy. Judging from the current energy consumption of various industries, the biggest energy-saving space is in lighting, which means that we must find a light source with environmental protection and energy saving. LED light source has gradually become the first choice to replace the traditional light source because of its long life, low energy consumption, environmental protection and other advantages. LED has advantages that other light sources cant match, which is a green lamp. China has selected 21 pilot cities to carry out LED road lighting, and LED street lamps are developing rapidly in China.展开更多

The main objective is to provide optimal solution between expensive safe design that utilizes continuous street lighting system at night for the entire road, or inexpensive design that sacrifices the safety, relying on using vehicles lighting, to eliminate the problem of high cost energy consumption during the night operation of the road. By taking into account both of these factors, smart lighting automation system is proposed using Pattern Recognition Technique applied on vehicle number-plates. In this proposal, the road is sectionalized into zones, and based on smart Pattern Recognition Technique, the control system of the road lighting illuminates only the zone that the vehicles pass through. Economic analysis is provided in this paper to support the value of using this design of lighting control system.展开更多

This design uses class of S spiral with the highest wind energy utilization rate, and the surface has materials that can absorb solar energy, its structure built in simple and the design fit standard proportion lamp. This design has the advantages of beautiful apnearance, easv to produce, has the very big use value.展开更多
