light pollution and street road lighting

With the acceleration of urbanization in recent years, outdoor lighting has attracted more and more attention from all aspects of society, and the quality of night lighting has become an important symbol to measure the modernization level of a city. However, there are many misunderstandings in actual work. Here I’d like to talk about light pollution and street road lighting.

       1.Lighting standard

One of the problems in road lighting is the improper selection of lighting standards. It may be that the illuminance was low in the past, but it is too high now.

In the past, the people did not pay enough attention to the road lighting in the city, the road lighting facilities were backward, and the illumination was insufficient. As a result, many motor vehicles turn on their headlights on the main road, and the light directly shines into the eyes of drivers and pedestrians of opposite-driving vehicles, causing strong disability glare, greatly reducing the speed of driving, and increasing the hidden danger of driving accidents.

Due to the obvious improvement of the lighting conditions, the driver has good vision and can turn off the lights to drive at high speed, thereby avoiding the strong glare formed by the lights.

On major urban roads with heavy traffic, sufficient illumination is beneficial.

       2.Lighting type and install method.

Many urban arterial roads have three road surfaces, which are illuminated by double-arm street lights. In this case, cut-off lamps should be used on the side of the motorway to reduce glare.

The installation elevation angle of street lamps is also an important factor affecting the glare index. CIE stipulates that the elevation angle of street lamps cannot be greater than 5, and its main purpose is to limit glare.

       3.Overpass lighting

High mast lights are known as the eyes of overpasses, and their applications are becoming more and more widespread. However, due to the lack of professional lighting designers in some overpass design units, they often only use one kind of high pole lighting, which causes many regrets.

In the overpass extension area, if the lighting type is not selected properly, one direction often meets the illumination requirements, while the light from other directions shoots out of the overpass area, which has a serious impact on the lives of surrounding residents. Therefore, the pole height and pole shape of the high pole lights at each position must be determined according to the different bridge types.

AIKO’s LED lighting to ensure adherence to industry standards can reduce your costs and energy production and improve nighttime conditions in your community while limiting the impact on the night sky.
