Abstract: Road lighting refers to the lighting for the road and its ancillary facilities. It is used to improve the safety of vehicles and pedestrians at night and prevent traffic accidents. Reasonable setting is conducive to improving traffic conditions, reducing driving fatigue, improving road capacity, and effectively reducing traffic accidents. So, how should road lighting choose lamps? Road lighting illuminators are high-pressure sodium lamps, low-pressure sodium lamps, electrodeless lamps, gold halide lamps, fluorescent lamps, new  street lights, solar street lights, LED and so on. The illuminator should use light energy rationally to prevent glare. Let’s take a look!

First, how to choose lamps for road lighting

Road lighting quality depends on:

1, the brightness of road lighting. It is strong enough to ensure that vehicle drivers and pedestrians can see obstacles on the road, pedestrians, vehicles and the surrounding situation of the road.

2, the uniformity of road lighting. That is, the distribution should be roughly even.

3, glare interference degree. That is to effectively control the harmful effects of glare on vehicle drivers and pedestrians.

4, the guidance of lighting. That is, appropriate Settings are carried out according to the road conditions, so that vehicle drivers and pedestrians can effectively obtain the direction and inclination of the road ahead, which is particularly important for roads with many curves and intersections. Reasonable use of lamps can prevent glare.

Common lamps:

Road lighting illuminators are high-pressure sodium lamps, low-pressure sodium lamps, electrodeless lamps, gold halide lamps, fluorescent lamps, new Solmin xenon street lights, solar street lights, LED and so on. Incandescent lamps, high-pressure mercury lamps and low-pressure sodium lamps have been gradually eliminated due to the performance defects of light sources. The illuminator should use light energy rationally to prevent glare. The light emitted by the illuminator should be irradiated along the required Angle and fall to the specified pattern on the road surface, the light distribution is uniform, the road surface is bright, and the glare is small. In order to reduce glare, light distribution control can be applied above the maximum light intensity.
