When solar lights up, the effect with normal street light there?

Why as outdoor lighting, solar street light popularity than the traditional street lamp? In addition to energy conservation and environmental protection, is the most intuitive illumination, under the same condition there?

now solar street lamps using LED light source, and the traditional street lamp is the widespread use of high pressure sodium lamp and low pressure sodium lamp, the above is of high pressure sodium lamp and LED street light night illumination contrast.

high pressure sodium lamp as the yellow light, color difference, leds for white light, good color rendering.

the illumination characteristics of both difference is obvious, high pressure sodium lamp luminous color is yellow, color temperature and imaging are relatively low, the sun's rays imaging index for 100, high pressure sodium lamp imaging index is only 20 or so.

and LED light source color temperature of light can - in 4000 7000 between flexible choice, development index, up to 80 above, lamps and lanterns light color is more close to natural light.

when night falls, solar street lamp lights up automatically, really night like day.

LED lighting and what is the advantage of high pressure sodium lamp lighting features?

low and high pressure sodium lamp light utilization rate is only about 40% of lamps and lanterns, lamp light Angle is 360 & deg; , most must arrive at the designated area by reflector reflection to

high utilization rate of LED light source of lamps and lanterns, about 90% of LED diode light Angle light Angle can be consistent with the lamps and lanterns, so most of the light of lamps and lanterns is direct exposure to the designated area, only a small number of through reflection.

low and high pressure sodium lamp bulb enable time is long, in 5 - current is switched on About 10 minutes of time, to reach normal brightness, again start time interval is greater than 5 minutes.

LED lights not startup latency problems can be switched on at any time, any work, able to achieve energy saving control is very convenient.

low sodium lamp as light with the light on temperature difference is big, if the lamp body without breathing system, reflector easily by the light of the corrosion of harmful gas to produce a larger loss.

low LED lights don't need to add the respiratory system.

the obvious advantages of solar LED street light and energy conservation, environmental protection, compared with the traditional street lights, solar street light more economic value and social value.
