What is the distance between outdoor lights?
Mar 07, 2024
The distance interval of outdoor lighting depends on the type, height, and type of light source used, as well as the specific requirements of the courtyard for lighting brightness. For example, a diffuse reflection courtyard light without a mask will scatter light everywhere. Generally, a 150W high-pressure sodium lamp is used, with a height of 3.5m to 4.5m and a spacing of 18m to 20m. A courtyard lamp with a face shield does not emit light everywhere, so sodium lamps and metal halide lamps can be used, suitable for 150W, with a spacing of about 16m.
In urban road lighting, the spacing between lamp posts can be determined based on the width of the road and the required lighting level. If the road is wide and requires high illumination, the distance between lamp posts will be relatively close, usually between 8-10 meters. If the road is narrow, the distance between lamp posts can be appropriately reduced, usually between 5 to 6 meters.
In short, the distance between outdoor lights needs to be reasonably arranged according to the usage scenario and the required lighting level. Our goal should be to minimize energy consumption and environmental impact while ensuring lighting quality.
