Indoor and outdoor lighting design methods, building facades, squares, green belt lighting

Indoor and outdoor lighting design methods. First let’s look at the outdoor lighting design.

First, building facade lighting

1, the building facade is an important place for people’s activities during the day, and its brightness directly affects people’s visual feelings.

2. The illumination of the facade of the building should meet:
1) In clear weather, to ensure that there is sufficient sunshine, the average illuminance of the wall is not less than 300l x;

2) Under rainy and snowy conditions, it can maintain a certain light intensity and uniformity;

3) When there is no street light at night, it can also ensure a certain brightness level (generally not less than 100 l x).

3. The calculation of the illumination of the facade of the building can use the following formula: the average illumination of the surface of the building = the amount of solar radiation received on the unit area/the area of the surface.

4, in order to ensure that pedestrians walk safely on the sidewalk on the street or under the pedestrian bridge at night will not be unable to see the road because the road is too bright. Therefore, it is necessary to properly treat the road surface with light.

5, according to the actual conditions of the road, the flow of people and the surrounding environment to determine the required road brightness.
Two, square lighting

1. The height of the light pole on the square should not exceed 10m.

2. The choice of lamps should take into account the convenience and safety of use.

3. The installation position of the lamp should consider the requirements of aesthetics and coordination with the surrounding landscape.

4. The arrangement of lights should be distributed reasonably and orderly.

5. Be careful to avoid glare.

6. Pay attention to prevent light pollution.

(3) Green belt lighting

1. The power selection of lawn lights should be determined according to the growth condition of the lawn.

2. If you use led as a light source, you must consider the problem of waterproof and dustproof.

3. Because the grass grows faster, it is recommended to use small lawn lights to reduce maintenance costs.

4. For some special terrain such as the ramp can be set up to illuminate these special areas.

5. For some places with dense trees, the way of tree array can be used for distribution control.

6. In some relatively open areas, you can choose to project high-power floodlights to increase the exposure range.
