LED street light the prominent advantages of what1

We all know this system belongs to the public lighting, road lighting it is controlled by the government, because the led street lamp has some characteristics of high efficiency, environmental protection, energy saving, long life, so government priority in use of road or a tunnel, then the simple introduce what else the advantage of it!

1, low energy lighting

there are a lot of high power led street light, has more than 100 lm/w, there are some companies in China they are specifically conducted an experiment, as early as in 2009 reached 160 lm/w. According to the U. S. department of energy (doe) predicts that by 2009 or so of high-power led products of photosynthetic efficiency could reach 165 lm/w, laboratory samples can reach 230 lm/w, led luminous efficiency basically won't have greatly improved, it will slowly will enter a phase delay.

2, long service life

the led street lamp means they will directly affect the whole road lighting and maintenance cost, high pressure sodium lamp and led the life expectancy of their definition is different, the average life span for the led means, the experiment is up to five percent of the amount of droop or to seventy percent of the time is the average life expectancy.

3, good color rendering

for the traditional street lamp although their photosynthetic efficiency high, but the line was very poor and color rendering, can only help people to detect the situation of the road, but can't help of pedestrians is very clear to identify the obstacles. So it came out the advantage of led, its color is very good, basically is close to the natural light, color is very true, and the color of the object itself can reflect more things, such lights can help in the process of drivers and pedestrians on the road to identify obstacles to provide better traffic conditions.

in addition to the led street lamp can quickly start, start time just need tens of nanoseconds, and will not restart the wait time. This kind of lighting and optical design, can be very ideal for light distribution, achieve high efficiency; The modelling of led lights with very strong plasticity, and structure is also very strong.
