Building landscape LED lighting design in the overall consideration of the following points is the first to confirm:
1. The direction of viewing
Buildings may be visible in different directions and angles, but generally before the design begins, we first decide on a particular direction to be the main direction of viewing.
Most people may see the distance. Distance between the distance will affect the appearance of observation for the clarity of the facade, while affecting the level of illumination decision.
3. Surrounding environment and background
The surrounding environment and the background of the light and dark will affect the subject of the required illumination. If the surrounding is dark, you need a little light to illuminate the main body; if the surrounding is bright, the light must be strengthened to highlight the main body.
In the building landscape LED lighting design, can be divided into the following steps:
4. Determine the desired lighting effect
Buildings may vary depending on their appearance and may have different lighting effects, or more uniform, or strong changes in light and shade; can also be more flat performance, or more lively performance, according to the properties of the building itself To decide.
5. Select the appropriate light source
Select the light source should be considered light color, color, efficiency, life and other factors. Light color and the external walls of the building material color is equivalent to the relationship between the general, gold brick, brown stone is more suitable for use of warm light to light, the use of light for the high pressure sodium lamp or halogen lamp.
6. Determine the required illumination
The illumination required depends mainly on the shades of the surrounding environment and the depth of the exterior of the building's exterior material. The recommended illuminance is for the main façade. In general, the secondary facade of the illumination of the main facade of the half, by the two sides of the bright and dark can show the building three-dimensional sense.
7. Select the appropriate fixture
In general, the square type of light-emitting light distribution angle is larger; round lamp angle is small; wide-angle lighting effect is more uniform, but not suitable for long-range projection; narrow-angle lamps for long distance projection , But close to use when the uniformity is poor.
8. Calculation of illumination and number of lamps
After the above steps are completed, according to the selected light source, lamps, installation location and other conditions of the illumination calculation to determine the number of lamps, so that the effect of the installation is completed as close as possible to the desired. The appearance of the building at night to use the lighting projection to be the performance of the results and the feeling of the day will be quite different. Therefore, in the LED lighting engineering design, the effect is not necessarily the same effect with the day, but it is important to show the characteristics of the building.
