In night scene lighting design, we often encounter a problem, which is also the most difficult to avoid, and that is glare.
The general causes of glare can be roughly divided into the following points:
1. The brightness of the light source (the higher the brightness, the more significant the glare);
2. The position of the light source (the closer it is to the line of sight, the more significant the glare will be);
3. Appearance size and number of light sources (the larger the apparent area, the greater the number of light sources, and the more significant the glare);
4. Surrounding environment (the darker the environment, the lower the brightness the eyes adapt to, and the more significant the glare).
So how to prevent glare in flood lighting design?
When designing flood lighting, the surrounding lighting environment must be fully considered. In order to ensure good uniformity, the spacing between lamps installed on the building should be 2.5 to 3 times the length of the bracket. If the spacing is too wide, then A sector-shaped bright area will be produced.
In flood lighting of buildings, the lamps can be illuminated from bottom to top, so that they are less likely to cause glare.
If side lighting is used, the shading of the lamps should be considered to reduce unnecessary light as much as possible. In flood lighting of buildings, the lamps are basically illuminated from bottom to top, so as to avoid glare to the greatest extent.
