Firstly, if the width of the road is 20 meters, it should be considered a main road, thus requiring lighting to be installed on both sides. The lighting requirements mainly include illumination level and uniformity, where the uniformity generally needs to be above 0.3. The greater the uniformity, the better the lighting effect.
Therefore, we can assume that there is a symmetrical installation of lights on both sides, with the pole height at least greater than half of the road width; therefore, the pole height should be between 12 to 14 meters. Assuming we use a 14-meter pole, the spacing for the streetlights is generally about three times the pole height, meaning the spacing should be at least 40 meters. Further assuming a spacing of 40 meters for the solar streetlights, with a pole height of 14 meters, the power of the solar streetlights would need to be above 200W to basically meet the lighting requirements of the main road.
Secondly, both illumination and power are related to the installation height of the lamps. For solar streetlights, we hope that the angle of the light being emitted is as large as possible. This way, the uniformity will also be good, allowing for increased spacing between the poles, reducing the number of poles needed and saving costs.
If the spacing of the solar streetlights is 40 meters, with a pole height of 14 meters and a power of 200W, how would the illumination be calculated? Therefore, we first need to test the 200W streetlights because different manufacturers use different LEDs, and the optical lenses also vary. The total luminous flux with the same power can differ, leading to different illumination levels on the road surface.
In summary, each company has its own standards, and specific issues should be analyzed accordingly. If you want to understand in detail, please consult a professional in street lighting.
