Lighting effects

Buildings because of their different appearance and may produce different lighting effects, or even feeling, or feeling strong shading; with a plain style, or the more lively performance, according to the characteristics of the building itself to decide.

Viewing direction: buildings may be different from the angle of the direction, can see, but generally in the design before proceeding, we must first determine a specific direction as the main viewing direction.

Distance: people may watch the distance. The distance of the distance will affect the clarity of the observation of the facade and the decision of the illumination.

Background: surrounding environment and the surrounding environment and background light will affect the body required illuminance. If the surrounding is very dark, you need a little light to illuminate the main body, if the surrounding is very bright light, it is necessary to strengthen the main body can be highlighted.

Wall materials: the wall of the building material is one of factors that affect the maximum effect of light.

Light source

Function type

Although the number of light sources, types and their individual properties will vary due to the scene, but there are three basic types: function key light, fill light and background light, together they coordinated operation.

Key light

In a scene, the main light source is usually called the key light. The key light is not only a light source, but it must be the main light source. It is usually the first to place the light source, creating a preliminary lighting effect in the scene.

Of light

Is a natural reflection, this type of light is usually called the ambient light, it improves the overall brightness of the scene.

The other is a simulation environment, the low intensity of the spotlight or floodlight is placed in a reasonable position in the scene. This type of auxiliary light should reduce the shadow area and add some light to the corners and corners that are not directly exposed to the critical light.

Background light

Background light is usually used as the "edge light", by illuminating the edges of objects, separating the object from the background. It is often placed on the opposite side of the 3/4 critical light.
