There are the following points which are the first to be confirmed when we design LED landscape lighting including the high power LED flood light projecting on the building.

1 , the direction of viewing : buildings can be seen from different directions and angle , but we have to generally decide to do a particular direction as the direction of the main viewing before the design.

2 , Distance: the viewing distance most people is likely to view. The distances affects the appearance of the facade of clarity to observe, while affecting the decision on level of illumination .

3 , the surrounding environment and context : the surrounding environment and context affect the brightness of the background illumination of the subject required . If the surrounding is very dark， a little light emitted by the high power LED flood light and other LED landscape lights need to illuminate the subject , if the surrounding is pretty bright，the light need to be highlighted to strengthen the body .

The high power LED flood light and other LED landscape lighting in the building design can be divided into the following steps :

1.Decides desired lighting effects

The different appearance of the building itself may produce different lighting effects , or more uniform feel , or shading strong feeling ; may be modest performance, or more lively expression, depend on the attributes of the building itself.

2 . Choose a suitable light source

Select the light source should be considered light color , color rendering , efficiency, longevity and other factors. There is the equivalent relationship between the exterior materials and color of the light -colored buildings, in general, by brick, brown stone is more suited to the use of warm light to illuminate，high pressure sodium or halogen light source is the preferable light source.

3 . Determine the required illumination

The required illumination mainly depends on brightness of the surrounding environment and the color of building exterior materials. Illuminance values ​​is proposed for the main facade . In general, the illumination of the secondary side of the vertical is half of that of the main facade , by the two faces of a different shade can show three-dimensional buildings.

4 Select the appropriate lighting

The light distribution angle ofhigh power LED flood light is generally large , round lighting angle is smaller. Wide-angle lighting effect is more uniform, but which is inappropriately suitable for distance projection ; narrow-angle lighting is suitable for more long-range projection, but the uniformity is poor using at close range.

5 Calculate the number of illumination and lighting

After the above steps are completed, how to determine the number of fixtures depends on the selected light illumination , lighting , installation location and other conditions of the calculation , so that the lighting is able to be as close as desired after the installation is complete . Appearance of the building take advantage of the projection of the high power LED flood light to performance at night , of which the effect will be difference with the feeling of the day . Therefore, for LED lighting engineering design, we do not necessarily need the same effect as the day proceeds , and it is important to show the characteristics of the buildings.Browsing http://www.lead-lighting.com/products/sid125-1.htm for more information about the high power LED flood light.
