How to choose lamps and road lighting devices for road lighting

1. How to choose lamps on road lighting

Road lightingThe quality depends on:

1. The brightness of road lighting.That is, there is enough strength to ensure that the vehicle drivers and pedestrians can see the situation around the roads on the road, pedestrians, vehicles and roads.

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

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

4. The guidance of lighting.That is, proper settings are made according to the conditions of the pavement, so that vehicle drivers and pedestrians can effectively obtain information such as the direction and tilt of the road ahead, which is especially important for many roads and cross -port roads.Reasonable application of lamps can prevent glare.

Common lamps:

Littors for road lighting include high -pressure sodium lamps, low -pressure sodium lamps, polar Lights, gold halogen, fluorescent lamps, new type of Suming street lights, etc.Candidates, high -pressure mercury lamps, and low -pressure sodium lamps have gradually been eliminated due to the performance defects of light sources.Littors should use light energy reasonably to prevent glare.The light emitted by the lighting should be irradiated along the required angle, falling into the specified graphic on the road, the light is evenly distributed, the road surface is large, and the glare is small.In order to reduce glare, light control can be controlled above the maximum light.

2. Road lighting device selection

The selection of light sources should comply with the following regulations:

1. Expressway, main roads, secondary roads, and branches should be used for high -pressure sodium Lights;

2. Motor vehicles and pedestrians in the residential area should adopt high -pressure sodium lamps or small -power metal halide lamps;

3. Merchant -vehicle traffic roads with high color recognition requirements for color recognition can be used in the city center and business centers. Metal halide lamps can be used;

4. The sidewalks on both sides of the pedestrian street, the pedestrian roads, and the traffic roads on the commercial area may adopt a small -power metal halide lamp, a fine pipe diameter fluorescent lamp, or a compact fluorescent light.

Road lighting should not use town flow high -pressure mercury lamps and incandescent lamps.

Outdoor lighting lamps and its auxiliary device selection

Motor lane lighting should adopt functional lamps that meet the following regulations:

1. Expressway and main roads must be intercepted or half -light lamps;

2. Half -light lamps should be adopted by the secondary road;

3. The branch road should be half -light lamps.

The non -motorized lanes that are necessary to set up lamps separately should be combined with functionality and decorative lamps that are necessary to set up Lights alone.When the decorative lamps are adopted, the on -light light ratio should not be greater than 25%, and the mechanical strength shall meet the provisions of the current national standard "General Safety Requirements and Experiments of the Lantern Festival" GB7000.1.

When using high rod lighting, according to the characteristics of the site, you should select a pan -light or interception lamp with appropriate power and light distribution.

When a closed road lighting is used, the protection level of the light source cavity should not be lower than IP54.The roads and venues of severe environmental pollution and difficulty in maintaining difficulties should not be lower than IP65.The protection level of the lamp appliance cavity should not be lower than IP43.

Activities or places with high corrosive gases such as acid -base in the air should adopt lamps with good corrosion resistance.

Large bridges such as traffic motor vehicles that are susceptible to vibrations are prone to vibration. The lamps adopted should meet the current national standard "lighting General Safety Requirements and Experiment" GB7000.1.

High -strength gas discharge Lights should be equipped with energy -saving inductors, and light sources with smaller power can be equipped with electronic ballasts.

The installation distance between the high -strength gas discharge lamp, the installation distance between the ballast and the light source should meet the product requirements.
