Do you know how to determine the height of the solar street light pole?

First of all, if it is a road with a width of 20 meters, it should be regarded as a main road, so it is necessary to arrange lights on both sides. In addition, the lighting requirements of the road mainly include illuminance requirements and illuminance uniformity. The uniformity is generally above 0.3. The greater the uniformity, the more diffuse the light of the solar street lamp, and the better the lighting effect.

Therefore, we can assume that it is a double-row symmetrical arrangement of lights, and the height of the street light pole is at least 1/2 of the width of the road, so the height of the light pole should be 12-14 meters; assuming a 14-meter light pole, the installation distance of the street lights is generally the light pole. It is about 3 times the height, so the distance is at least 40 meters; then assume that the solar street lights have a distance of 40 meters and the pole height is 14 meters. In this case, the power of the solar street lights must be above 200W, which can basically meet the lighting of the main road. Require.

Secondly, illuminance and power are related to the installation height of lamps. For solar street lights, we hope that the larger the angle of illumination, the better, so that the uniformity will be good, and the distance between the light poles can be increased, reducing the number of light pole installations and saving costs.

Finally, if the solar smart street light has a distance of 40 meters, the height of the street light pole is 14 meters, the power is 200W, and the lights are arranged on both sides, how is the illuminance calculated? Therefore, it is necessary to test the 200W street light first. , Because the street lamps of different manufacturers use different LEDs, the light distribution lenses are also different, and the total luminous flux of the same large power will also be different, which will lead to different road illumination.
