Wash the wall


Wall washing can be said to be the most frequently used technique in exterior wall design at present. You can understand it as using hidden lamps to brighten all walls at a certain angle, just like girls using soft light to broadcast live, the face is soft. The light effect is the most beautiful when taking selfies. Generally speaking, it can have an overall brightening effect, and it will look clean and elegant.

Spotlights are generally used as wall-washing tools in home decoration. The effect of wall-washing is first to emphasize the uniformity of light.


You can use the lamps used to wash the walls to achieve the effect of wall washing. The lamps are often installed far away from the wall. The conventional practice is that the distance between the lamps and the wall is the height of the illuminated wall (normally 2.7 to 2.7m). There are special wall washer spotlights that can adjust the spacing appropriately) 1/3 to 1/5. The wall washer is suitable for use on the smooth and uniform wall surface such as paint, which makes the heavy wall look lighter.

Wipe the wall


Wall cleaning effect, if the wall cleaning is a soft light effect, then the wall cleaning is a highlight effect, using the uneven texture effect of the material to create a sense of light and shadow.


You can use the downlight to make the wall cleaning effect, and use the smallest angle to rub the light on the wall to highlight the visual effect brought by the texture of the wall itself. Generally, it is recommended that the distance between the lamp and the wall and the height of the illuminated wall be less than 1:5 or less than 30cm. Use light with a narrow beam angle to wipe the wall.

Use linear lights for wall lighting

The method of wiping wall lighting: Arrange the light source as close as possible to the light-receiving surface, and wipe the light on the wall with a very narrow beam. The beam angle of the lamps used should not be too wide. It is recommended to use narrow beam lamps with adjustable direction to adjust the distance from the wall (professional line lamps can also replace downlights).


Internal penetration


It can be simply understood that the light shining from the inside of the illuminated object is internal penetration. The common one is the lantern, and the famous Chinese Water Cube also has this lighting effect.

Inner penetration can be made through reasonable design and manufacture of various artistic light-transmitting effects such as patterns and texts. Most of the effects are expressed as atmosphere lighting effects. The most direct function of the internal penetration effect is to reduce glare, which can create more lighting effects, highlight transparency and structure.


The internal penetration effect is common in all kinds of ambient lights, and many home entrances are used

Of course, there are many lighting methods. These three lighting methods, wall washing, wall cleaning and internal light transmission, have more prominent effects than ordinary lighting methods.
