Building lighting engineering, as a common type of lighting engineering, can be seen everywhere in cities. So do you know how that colorful light achieves its effect? How does the building lighting project achieve a beautiful lighting effect?
Firstly, the lighting project of the building should consider selecting suitable light sources. The selection of light sources should consider factors such as light color, color rendering, efficiency, and lifespan. The color of light is closely related to the material and color of the exterior walls of buildings. Generally speaking, bricks and yellow brown stones are suitable for using warm light for illumination. In this case, floodlights or halogen lamps should be chosen as the light source.
Secondly, the lighting engineering of the building should choose lamps with higher cost-effectiveness. The shape of a lamp directly affects its lighting angle and uniformity of light. Generally speaking, square projectors have a larger angle of light distribution, while circular lamps have a smaller angle. Wide angle lighting fixtures have a more uniform effect, but are not suitable for long-range projection; Narrow angle lamps are suitable for long-range projection, but their uniformity is poor when used at close range.
Furthermore, the lighting project of the building should consider the characteristics of the building itself. The lighting design of the building should be based on the appearance characteristics of the building itself, especially the lighting effects produced by different building appearances may also be different. Some lights are called uniform, and some have strong changes in light and shade. We can choose a flat or lively way of expression according to the properties of the building itself.
Finally, the lighting project of the building should consider the illuminance and the quantity of lighting fixtures. As we all know, one factor that must be considered in lighting engineering, especially in building lighting engineering, is the illuminance value. The illuminance value is set for the main facade. The illuminance value is influenced by the surrounding environment and exterior wall materials of the building, and its lighting effect is also different. Generally speaking, the illumination of the secondary facade is half of that of the main facade, and the difference in brightness between the two sides can demonstrate the three-dimensional sense of the building.
As for the number of lighting fixtures for the building lighting project, it depends on the light source, installation location, and illuminance we choose. The appearance of the building is reflected by the projection of lights at night, and the resulting effect will be equivalent to the feeling during the day. Therefore, in the design of LED lighting engineering, we do not necessarily need to achieve the same effect as during the day. It is important to express the characteristics of the building.
The above are the factors that need to be considered when designing the effect of building lighting engineering. To achieve a perfect lighting effect, building lighting engineering must follow the above principles
