1. Determine the desired lighting effect
Buildings may have different lighting effects due to their different appearances, or a more uniform feeling, or a feeling of strong changes in light and shade; It depends on the properties of the building itself.
2. Choose a suitable light source
The choice of light source should consider factors such as light color, color rendering, efficiency, and life. The light color has an equivalent relationship with the color of the exterior wall material of the building. Generally speaking, bricks and yellowish-brown stone materials are more suitable for irradiation with warm color light, and the light source is high-pressure sodium lamp or halogen lamp. White or light-colored marble can be illuminated with cool white light with a higher color temperature (complex metal lamp), but high-pressure sodium lamps are also used.
3. Determine the required illuminance
The required illuminance mainly depends on the light and shade of the surrounding environment and the color of the exterior wall material of the building. Generally speaking, the illumination of the secondary facade is half 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.
4. Decide how to illuminate the subject
According to the characteristics of the building and the current condition of the building base, the most appropriate lighting method is determined to achieve the desired lighting effect.
5, choose the appropriate lamps
Generally speaking, the light distribution angle of square-shaped
floodlights is larger, and the angle of circular lamps is smaller. 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 have poor uniformity when used at close range. You can also choose
Led Point Light sources,
line lights,
grid screens, wall washers, etc.In addition to the light distribution characteristics, the selection of lamps and lanterns is also a factor that must be considered.
