LED architectural landscape lighting design

LED landscape lighting design of buildings in the whole of the first to consider the following points to be confirmed:

1, Viewing direction
Buildings may be can be seen from different directions, angles, but generally begin before the design, we need to determine a particular direction as the direction of the main viewing.

2, Distance
Perhaps most people viewing distance. The distances will affect people for the observation of the appearance of the facade clarity, affect the illumination level decisions.

3, Surroundings and background
Surroundings and background shading can affect the body the required illumination. If the surrounding is dark, you need a little light is enough to illuminate the subject; if the surrounding is very bright, the lights will be able to highlight the need to strengthen the body.

LED landscape lighting in the building design, it can be divided into the following steps:

1, Determine the desired lighting effects
Because of their different appearance of the building itself, which may produce different lighting effects, or more uniform brightness changes or strong; it can be relatively modest expression, or the more lively expression, the properties are following the building itself to decide.

2, Select the appropriate light source
Select the light source should be considered light color, color rendering, efficiency, life and other factors. Material color light color exterior walls of the building there is the equivalent of the relationship, in general, BRIC, tawny stone is more suitable for the use of warm light irradiation using a light source for the high-pressure sodium lamps or halogen lamps.

3, Decision required illuminance
Illuminance required depends on the brightness of the surrounding environment and the building facade material depth of color, it is recommended illuminance values are for the main facade. In general, secondary illumination facade of the main facade of the half, by shading the two surfaces can exhibit different three-dimensional structures.

4, Select the appropriate lighting
Generally, spot light distribution angle square of the larger wire; angle smaller circular lamps; wide-angle lighting effect is more uniform, but not suitable for long-distance projection; narrow angle luminaires suitable for more distant projection but at close range using the evenness poor.

5, Calculate the number of lamps of illumination
After the above steps are completed, according to the selected illumination of light, lighting, installation location and other conditions of the calculation to determine the number of lamps, the effect after installation is complete in order to be able to be as close as expected. Appearance of the building at night to take advantage of projected light performance, feeling its resulting effect during the day there will be a considerable difference. Therefore, in the LED lighting engineering design, the resulting effect is not necessarily with the same effect during the day, it is important that the characteristics of the building shown.
