In the LED lighting design of the landscape of the building, the following factors should be considered comprehensively:


1, the building's own properties


Different appearances of buildings will result in different lighting effects, so it is necessary to decide which form of expression to use according to the properties of the building, or to be more level or lively.

2, the surrounding environment and background


The brightness of the surrounding environment and background will affect the illuminance required by the building. If the surroundings are dim, a small amount of light is needed to illuminate the building; if the perimeter is bright, the lights must be reinforced to highlight the building.


3, viewing distance


Under normal circumstances, the distance of viewing distance will directly affect people's observation of the clarity of the building, while affecting the level of illumination.


4, viewing direction


Buildings are generally visible from multiple directions and angles, but generally before starting the lighting design, it is necessary to determine a particular direction as the main direction of viewing.


5, choose the light source


When selecting a light source, consideration should be given to many factors such as light color, color rendering, efficiency, and lifetime. The color of the exterior wall material of the building plays a decisive role in the choice of light color. Generally speaking, the brick and yellow-brown stone are more suitable for the use of warm color light, and the light source is easy to select high-pressure sodium lamp or halogen lamp.


6, choose the lamp


Generally speaking, the square-shaped light distribution line has a large distribution angle, and the circular lamp has a small light distribution angle. The wide-angle type lamp has a relatively uniform light distribution , but is not suitable for long-distance projection; on the contrary, the narrow-angle type lamp is suitable for far-reaching It is projected, but the uniformity is poor when used at close range.


7, the required illumination


The required illumination depends mainly on the brightness of the surrounding environment and the color of the exterior wall material of the building. It is recommended that the illumination value be set for the main facade. Generally speaking, the illuminance of the secondary façade is half of the main façade, and the three-dimensional effect of the building is expressed by the difference in brightness between the primary and secondary façades.


8, calculate the illumination and the number of lamps


The number of lamps is determined according to the illuminance of the selected light source, the lamp, the installation position, etc., and the effect after the installation is completed is as close as expected.
