1. How bright is the street light in the residential area?
The brightness adjustment of the street light in the residential area is a big problem, mainly because the street light is too bright, which will cause the residents on the lower floors to feel dazzling. , light pollution is also more serious; and if the street lights are too dark, it will affect the owners of the community to travel at night, pedestrians and vehicles are prone to accidents, and thieves are prone to commit crimes in the dark, so how bright is the street light in the residential area?
In fact, my country has expressly stipulated the brightness standard of street lamps in residential areas. According to the “Design Standards for Urban Road Lighting”, the brightness standard of residential roads as branch roads should be about 20-30LX. , that is, people can see clearly within the range of 5-10 meters. The failure of lighting in some residential areas is mainly due to the reduction of lighting requirements by developers and property owners in order to save costs and use electricity. In addition, when designing residential street lighting, since the branch roads are narrow and distributed among residential buildings, the uniformity of street lighting needs to be considered. Generally, it is recommended to use single-sided lighting with low-pole lighting.
Second, residential street lamp installation specification requirements
1. Lamp type
Width of residential road Generally, it is 3-5 meters. Considering the factors of illuminance and convenient maintenance, courtyard lights with a lamp height of 2.5 to 4 meters are generally used for lighting in the community, so that the brightness is more suitable, and it is also convenient for maintenance personnel to quickly repair when there is a problem with the street lights. . And the garden lamp can pursue the beauty of the overall lamp type according to the architectural style and environmental atmosphere of the community, and beautify the community.
In addition, the shape of street lamps should also be simple and smooth, and there should not be too many decorations. If there is a large area of lawn and short flowers in the community, some lawn lamps can also be considered.
2. Light source
Different from the high-pressure sodium lamps commonly used in main road lighting, the main light source used for residential lighting is metal halide lamps, which use cool-color light sources. The metal halide lamp can create a sense of tranquility, which can make the whole community rich in layers, and create a soft outdoor environment for low-floor residents to avoid light pollution at night.
The lighting of the residential area also needs to consider the vehicle factor, but the vehicles in the residential area are not like the vehicles on the main road, and generally drive relatively slowly, so the pursuit of brightness uniformity is not high, mainly in some areas such as The brightness of the main entrance, intersection and public area is relatively high, while the brightness of other places is low.
3. Lighting layout
Because the road conditions of the residential roads are more complex, with many intersections and forks, the residential lighting should be better. For visual guidance, it should be arranged on one side; in the main roads and entrances and exits of residential areas with wider roads, it can be arranged on both sides.
In addition, when designing residential lighting, care should be taken to avoid the adverse impact of outdoor lighting on the indoor environment of residents. The lamp position should not be too close to the balcony and windows, and should be arranged in the greenery on the side of the road away from the residential building. in-band.
4. Power supply and distribution settings
For residential areas with a small area, the lighting distribution box is generally located in the center of the area and transmits electricity to the surrounding areas. It is a center-and-radiation type, the line is not long, but there are many branches; and some large-scale residential areas have many lamps, and multi-point power transmission is often used, which can not only solve the pressure drop loss, but also facilitate future pipeline maintenance, but The cost is slightly higher.
The street lamp power supply and distribution point can be integrated into the street lamp control network after being connected with the control cable, and can also be equipped with control equipment such as wireless remote control.
