Street is an important part of urban lighting, traditional street lamps often used high-pressure sodium lamp, high-pressure sodium lamp low overall glazing effect shortcomings caused a great waste of energy. Therefore, the development of new type of high efficiency, energy saving, long service life, color index is high, the environment protection of the street of city energy-saving has very important significance.

First, Light LED is a semiconductor diode, which has a very long life. When the flux attenuation to 80％, the life expectancy of 25000 hours. The metal halide lamp life in 6000~12000 hours, high pressure sodium lamp life of 12000 hours. LED street lamp life longer.
Secondly, the basic structure of the LED light is a electro luminescent semiconductor materials, placed on a wire rack and surrounded by epoxy resin seal, to protect the internal core wire, so the seismic performance of the LED light is good.
Third, white LED Tube color than the high-pressure sodium lamp. In the middle of the visual level, the human eye in the high temperature environment under low color temperature environment more easily identify things. The color rendering of white LED light also than high pressure sodium lamp and a lot of good, high pressure sodium lamp color rendering index only 20 left and right, and white LED light can up to 65 to 80. LED street lamp is better.
Fourth, LED Light can achieve the dimming function more perfect. Because of the large working range of Light LED, the output of the optical output is proportional to the working current, so it can be reduced by the method of the current. Also due to LED light frequent switch without too much damage to its, LED light light can also the method to getting the pulse width modulated by adjusting the voltage duty ratio and frequency, can effectively regulate the luminous intensity of the LED tube. LED street lamp more efficient and convenient.
