Solar street light poles have a multi-faceted impact on traffic safety. From the perspective of lighting, street lights installed on street light poles can provide sufficient lighting for the road. In urban road lighting systems, the projection angle of street lights is a crucial parameter. It is directly related to the lighting effect and coverage, which in turn affects the safety and efficiency of night driving.

First, the right illumination angle can provide good visibility. Road lighting lights should have sufficient brightness and be evenly distributed on the road to ensure that the entire road is illuminated. This can improve the driver's visibility and reduce the risk of traffic accidents. For example, the illumination distance of the low beam is generally around 30 meters. When adjusting, the tangent level of the light should be ensured, neither too high to illuminate the eyes of the oncoming vehicle driver, nor too low to cause the illumination distance to be too short. 2. The illumination distance of the high beam is farther, usually more than 100 meters. When adjusting, be careful not to be too high to avoid dazzling other vehicles.

Secondly, unreasonable illumination angles may cause safety problems. If the light is not adjusted properly, high or low beams that are too high may blind the driver of the oncoming vehicle for a moment, increasing the risk of a collision. In addition, uneven lighting may prevent the driver from clearly seeing obstacles or pedestrians on the road at night or in bad weather conditions, thereby increasing the possibility of accidents.

The illumination angle of the light pole is closely related to road safety, which is mainly reflected in the following aspects:

Lighting uniformity: Ensure that the light on the road is evenly distributed to avoid areas that are too bright or too dark. Uniform lighting helps drivers and pedestrians see the road conditions clearly, thereby reducing the possibility of accidents.

Reduce glare: Improper angles may cause glare and affect the driver's vision. By optimizing the installation angle and beam angle of the lamp, glare can be effectively reduced and road safety can be improved.

Coverage: The appropriate illumination angle can ensure that the light covers the entire road and sidewalk, helping drivers and pedestrians to more clearly identify the surrounding environment and potential dangers at night.

Visual comfort: The appropriate illumination angle can improve visual comfort, reduce visual fatigue, and allow drivers and pedestrians to better concentrate, thereby improving traffic safety.

By considering these factors, designing a reasonable lighting angle of the lamp pole can significantly improve the nighttime safety of the road.
