In the design of facade lighting, the direction and color of the light are the decisive factors that affect the facade image of buildings. The facade lighting design adopts a combination of different lighting designs and control methods, so that the building at night is no longer dark and ordinary, and the facade of the building presents a different image. Appropriate facade lighting can create a lively and lively building. It can also expand the commercial value of the building. In this article, Suntech will share with you how to design facade lighting, as well as typical cases of facade lighting.
Facade lighting usually needs to be based on the actual situation of the building. The following is how we summarize the lighting design of 7 different types of buildings:
Floodlighting a solid facade flattens the facade while accentuating the surface texture of the facade material. As the facade rises, the brightness of the facade will gradually decrease, and there will be a gradual transition from light to dark from the ground to the sky.

The narrow light projections of the vertical dividing facades enhance the facade effect of the facade divisions. To avoid shadows, the luminaires should be positioned correctly and the lighting direction should be parallel to the facade. The outdoor lighting of columns should choose the narrow beam angle spotlight to emphasize the height of the building.

For buildings with multi-layered eaves horizontally divided, when light is projected onto the horizontally divided facades, long and heavy shadows will appear on the raised parts of the facades, and upward lighting close to the facades will produce hierarchical shadows, from bottom to top The sense is gradually weakened, thereby enhancing the three-dimensional effect of the building.

Another most common way is to arrange LED linear lights on the horizontal partition structure of the facade to represent the horizontal partition of the building.

Generally speaking, different parts of the concave and convex facade can be treated with different illuminances or different light colors to enhance the rhythm of the facade appearance. Using wide beam angle floodlights will reduce the contrast between elevation bumps, making the building visually more "flat".

When opening windows or openings for architectural facade design, it should be noted that the lighting of the facade should not cause glare to indoor people. The general use of floodlights and line lights to accentuate the outline of a window or hole enhances the symmetry and drama of the building.

For the strip-shaped layered facade, the contrast between the bright windows (interior) and the dark facade (exterior) is intensified by spreading light from the inside to the outside.

During the day in daylight, the transparent facade of the building is dark and reflects the surrounding environment. And at night, interior lighting allows one to see the inside of the building. Glazing on the top of the interior enhances the building’s presence, making the interior brighter at night, and the facade’s framing creates a silhouette effect.

The transparent media facade lighting adopts a double-layer glass curtain wall system. The outermost layer is a decorative curtain wall, using ultra-white dotted glass with a coverage rate of 50%. The inner side of the building is a curtain wall with a medium gray glass. It does not block the view of the interior, nor does it destroy the original aesthetic design of the building.

If you want to understand the design of facade lighting, you must first distinguish the two most commonly used modern exterior lighting methods which are easily confused-- wall washing and grazing.
Wall washing refers to illuminating the wall with lights evenly like washing the wall, you can make the wall not produce shadow patches by evenly distributing the lamps on the whole wall from top to bottom or from bottom to top.
Evenly illuminated wall washes give walls a clearer and brighter appearance.
It also helps to better enhance the structure of the wall.
Washing the walls makes the room look more lively as a whole.
Grazing walls are another form of surface facade lighting that is the opposite of the wall wash effect. This is achieved by providing the fixture closer to the wall so that the lux level decreases with distance from the fixture. Luminaires can be placed on the ground and focused upwards to create a mystical, enchanting or captivating effect on surfaces
Wall grazing helps make textured vertical surfaces more visible or prominent by enhancing shadows.
Makes the textured surface of the wall more aesthetic.

The difference between grazing and wall washing is that the light cast on the surface of the building is not uniform and creates very pronounced or pronounced shadows. Click here to learn more about the difference between wall washing and wall grazing.
Wall washing or grazing needs to choose a suitable method according to the project area and distance. It is worth noting that the projection distance of the lamps is related to the lens and power. The higher the power, the brighter the projection brightness, the narrower the lens angle, and the longer the projection distance.
The lighting effect should be determined according to the actual situation/mood/occasion: RGB or RGBW and other lighting change effects and DMX512 control, DMX512 changes more widely, depending on the actual needs. Create millions of color combinations with the above-mentioned fixtures and accessories. Lighting effects can be changed according to the occasion and atmosphere of the festival.
