he overall consideration of the landscape LED lighting design of the building has the following points to be confirmed first:
1 .Direction of viewing
The building may be visible from different directions and angles, but before designing, we must first decide on a specific direction as the main viewing direction.
Possible viewing distance for 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 brightness of the surrounding environment and background will affect the illuminance required by the subject. If the periphery is very dark, a little light is needed to illuminate the subject; if the periphery is very bright, the light must be strengthened to highlight the subject.
The LED lighting design of building landscape can be roughly divided into the following steps:
4 .Decide the desired lighting effect
The building may have different lighting effects due to its own appearance, or it is more uniform, or the light and dark changes are stronger; it can also be a more flat expression or a more lively expression, depending on the properties of the building itself To decide.
5 .Choose a suitable light source
The choice of light source should consider factors such as light color, color rendering, efficiency, life and other factors. The light color has an equivalent relationship with the color of the outer wall material of the building. Generally speaking, golden brick and yellowish brown stone are more suitable to be irradiated with warm color light, and the light source is high-pressure sodium lamp or halogen lamp.
6 .Decide the required illumination
The required illuminance mainly depends on the brightness of the surrounding environment and the shade of the color of the external wall material of the building. The recommended illuminance value is for the main facade. Generally speaking, the illumination of the secondary façade is half of the main façade, and the three-dimensional appearance of the building can be expressed by the difference in the light and shade of the two façades.
7. Choose the appropriate lamp
Generally speaking, the angle of distribution of the light beam of the square type is larger; the angle of the round type lamp is smaller; the effect of the wide-angle type lamp is more uniform, but it is not suitable for long-distance projection; , But the uniformity is poor when used at close range.
