Led Street lights Introduction

 

The so-called led street light, is a light emitting diode as the main material to make use of the outdoor lighting, which are capable of emitting, mainly because of weak energy we use will make it the semiconductor PN junction achieve luminous effect, meaning that is, we are in a certain forward bias voltage and current situation, the injected electrons and P area N area when diffused through radiative recombination to emit light.

 

Advantages Led lights

Led lights has been able to widely welcomed by the people of the amount, because they have the following advantages:

1, led street lamp design is the use of secondary optical design form, we will be led street light shines on the area needed for lighting, enabling more efficient lighting, and therefore, in many places are willing to choose to use led lights.

2, led street light failure is very small, very long service life, led lights in use 10 years later it still has a high value, the light fades in the course of their constant use in less than one year, and 3%.

3, led street light-emitting diode is a low-voltage devices, voltage safe to use, especially use it in public places.

4, led lights for a long period of use, it can be used more than 50,000 hours.

5, led street light belongs unidirectional, diffuse the situation does not occur, to ensure the efficiency of light.

 

 

The disadvantage Led lights

In a perfect lighting also has its own shortcomings, led lights, too, their shortcomings are the following:

1, although the low level of light failure led lights, but this is basically for high-power led lights, and small power led street light failure is quite large.

2, Led street light color is white, due to the defects in the manufacturing process on the individual, as well as with the error of the lens, so when using readily form a yellow circle, it will affect the effect of light shining.
