LED street light with its own development and progress of technology, development trend in the city is not when, it LED lamps and lanterns in the double advantage of energy conservation and environmental protection, LED street light should be the north has been gradually formed the scale, designs city-lighting project. The influence of road lighting field play an important role. LED street lamps and lanterns is made of LED lamps and lanterns, which is as cold light source products, with high cost performance, green environmental protection, safe and reliable, stable quality, long service life, easy installation and maintenance and other characteristics, can be widely used in city lighting engineering, for example, road lighting, building lighting, green lighting, garden plaza lighting, advertising light box, lighting, urban landscape lighting lighting and home lighting systems. From understanding, ordinary street lamp lighting the consumption accounted for about twenty percent of the whole power consumption, lower the electricity needed to lighting is an effective way of energy saving. In order to be able to achieve this goal, the development and application of more durable, safe, reliable and efficient new light source is imperative. Precisely, LED light source has the characteristic, so the LED street light to choose the LED lamps and lanterns is a wise choice. LED street lights, LED lighting as the light source of green energy conservation and environmental protection, the advantages of low power consumption, high luminous efficiency, safety and reliability, long life and other characteristics. On the premise of the same lighting effect, power consumption is half of the fluorescent tube, one over ten thousand of the incandescent light bulb; According to the relevant department estimated that if the LED lighting lamps and lanterns in alternative half of Japan's incandescent lamp and fluorescent lamp, can save the equivalent of six billion litres of crude oil a year. With the rapid development of economy in our country, the lighting of the power consumption is greatly needed to improve, the study of the green energy-saving lighting applications, will be more and more be taken seriously. Thus, LED street lamp development is inseparable from its chosen LED light source, it can let the road in the night light, greatly facilitates people's travel activities.
