LED street light source VS traditional street light source what is the difference?

LED lamp is a kind of semiconductor diode, its life is very long. When the luminous flux is reduced to 80%, the service life is up to 25000 hours. The life of the metal halide lamp is 6000~12000 hours, and the service life of the high-pressure sodium lamp is 12000 hours.

The street is an important part of city lighting, traditional street lamps used high-pressure sodium lamp, the overall light low pressure sodium lamp caused a huge waste of energy, therefore, the development of efficient, energy saving, long life, high color rendering index, green street has very important significance to energy saving lighting city.

As the light source of LED street lamp, LED lamp has many advantages compared with the traditional street lamp light source.

First, the LED lamp is a semiconductor diode, its life is very long. When the luminous flux is reduced to 80%, the service life is up to 25000 hours. The life of the metal halide lamp is 6000~12000 hours, and the service life of the high-pressure sodium lamp is 12000 hours. LED street lamp life longer.

Second, the basic structure of LED lamp is an electroluminescentsemiconductor materials, placed on a wire rack, then sealed with epoxy resin around, to protect the internal core function, so the seismic performance of LED lamp is good.

Third, the white light of LEDTube than the high pressure sodium lamp good. In the middle of the visual level, the human eye in the high temperature environment under low color temperature environment more easily identify things. White LED lamp color rendering is also much better than the high-pressure sodium lamp, high pressure sodium lamp color rendering index is only 20 right left, while the white LED lamp can reach 65~80. Better color rendering of LED street lamp.

Fourth, LED lamp can achieve a better dimming function. Because of the large range of LED lamp, the light output is proportional to the working current, so it can reduce the current to adjust the light.

In addition, due to frequent switching of LED light without too much damage to the LED lamp dimming can also be used to obtain the pulse width adjustment method, by adjusting the duty ratio of the voltage and frequency, can effectively adjust the luminous intensity of LEDTube. LED street lamp is more efficient and convenient.
