There are many advantages of LED

LED lamps as light source, which, more traditional street lighting has many advantages.

1, each unit LED die only a very small volume, it can be fabricated into various shapes of the devices, and is suitable in the volatile, easy to shock environment;

2, long life: theoretical life can use the 5-thousand hours;

3, LED can be frequent switching and forget about the damage;

4, easy to install: LED street lamp directly installed on the poles to replace the original sodium lamp;

5, excellent thermal control: LED junction temperature can fall below 70 ° C, with the technology, the junction temperature still further decline in the lower junction temperature, in theory, the longer life of LED chips;

6, quality, reliable: the circuit power supply used in all high-quality components, each LED has a separate stars and series-parallel overcurrent protection, even if one is damaged, it will not lead to other LED chip failure;

7, LED light source does not contain toxic metals mercury, unlike high-pressure sodium or metal halide lamp in the end of life as damaging the environment;
   

8, LED street lamp itself directional light, there is no diffuse light to ensure the luminous efficiency;

9, LED street lamp has a unique optical design of the secondary will be required for LED street lamps lighting the light hitting the region, that is the road to further improve the light efficiency and achieve energy-saving purposes;

10, LED light source efficiency of the current has reached 100lm / W, but there is still much room for development, the theoretical value can reach 250lm / W. The high-pressure sodium light-emitting efficiency is only increased with the power increase, and therefore, the overall luminous efficiency LED lights stronger than the high-pressure sodium lamp;

11, LED street lamp light color rendering than the high-pressure sodium lamp, high pressure sodium lamp color rendering index is only 23, while the LED lights color-rendering index can reach 75 or more, from the visual psychological point of view, to achieve the same brightness, LED street lamp illumination average of 20% lower than the high-pressure sodium lamp above (modeled on the UK road lighting standards); Moreover, in the middle of the visual level, the human eye in high color temperature environments with low color temperature than the environment more easily identify things, to avoid the occurrence of certain dangerous state;

12, LED street light decline is small, one-year decline of light less than 3%, using 10 years of road use is still to reach illumination requirements, therefore, LED street lamp design, the use of power can be lower than the high-pressure sodium lamp;

13, LED lights can be automatically dimming can be achieved at different times to meet the lighting requirements, the maximum possible reduction in power, to save energy;

14, LED is a low-voltage direct current devices, drive a single, LED voltage for safety voltage, so it is a more secure than the use of high voltage power supply, especially for public places. Dc characteristics make LED especially suited to solar energy, wind power to combine;
