In the overall consideration of the landscape LED lighting design of the building, the following points should be confirmed first:
1 viewing direction
Buildings may be seen from different directions and angles, but generally, before starting the design, we must first decide on a specific direction as the main viewing direction.
2 distance
The possible viewing distance of the average person. The distance will affect the clarity of people's observation of the facade appearance, and also affect the decision of the level of illumination.
3 Surrounding environment and background
The light and shade of the surrounding environment and background will affect the illumination required by the subject. If the perimeter is dark, a little light is needed to illuminate the subject; if the perimeter is bright, the light must be intensified to bring out the subject.
In building landscape LED lighting design, it can be roughly divided into the following steps:
4 Determine the desired lighting effect
Buildings may have different lighting effects due to their different appearances, or they may be more uniform or have strong changes in light and shade; they may also be more plain or more lively, depending on the properties of the building itself. to decide.
5 Choose a suitable light source
Factors such as light color, color rendering, efficiency, and lifespan should be considered when selecting a light source. The light color has an equivalent relationship with the color of the exterior wall material of the building. Generally speaking, golden bricks and yellow-brown stone are more suitable for irradiation with warm color light, and the light source is high-pressure sodium lamp or halogen lamp.
6 Determine the required illuminance
The required illuminance mainly depends on the light and shade of the surrounding environment and the color of the building exterior wall material. The recommended illuminance value is for the main facade. Generally speaking, the illumination of the secondary facade is half of that of the main facade, and the three-dimensional effect of the building can be expressed by the difference in light and shade between the two sides.
7 Choose the right light fixture
Generally speaking, square-shaped floodlights have a larger distribution angle; round-shaped lamps have a smaller angle; wide-angle lamps have a more uniform effect, but are not suitable for long-distance projection; narrow-angle lamps are suitable for long-distance projection , but the uniformity is poor when used at close range.
8 Calculation of Illuminance and Number of Lamps
After the above steps are completed, the number of lamps is determined according to the illuminance calculation of the selected light sources, lamps, installation positions, etc., so that the effect after installation can be as close as possible to the expected. The appearance of the building is expressed by the projection of lights at night,
The resulting effect will be quite different from how it feels during the day. Therefore, in the design of LED lighting engineering, the effect obtained is not necessarily the same as that of the daytime, but it is important to show the characteristics of the building.
