Emergency Light Manufacturers introduced the principles and requirements of floodlighting as follows: to master the characteristics of the building facade, illuminate from several different angles to produce a significant three-dimensional effect, especially to produce the layered effect of light and color; to highlight the building facade, Make it form a contrast with the surrounding environment, and give full play to the role of the surrounding environment; the material color and texture of the details of the building facade can be seen from close, and the volume and light color of the building can be seen clearly at a distance; Understand the reflectance of building facade materials to light, and determine the required illuminance on this basis.
To make the surface lighting look balanced, all shadows should be cast in the same direction, and all lamps that illuminate the surface in a projection area should have the same projection direction. For example, if two lights are symmetrically aimed at the vertical direction of a surface, the shadows will be reduced and chaos may appear. Therefore, it may not be possible to see the surface fluctuations. However, large protrusions can produce large dense shadows. To avoid destroying the integrity of the facade, it is recommended to provide weaker lighting at an angle of 90° to the main lighting to weaken the shadows.
According to the characteristics of the building itself, the floodlight should be set as far away as possible from the building. To obtain more uniform brightness, the ratio of the distance to the height of the building should not be less than 1/10. If the conditions are restricted, the floodlight can be installed directly on the building body. When designing the facade structure of some foreign buildings, the appearance of the lighting needs is considered. There is a special installation platform reserved for floodlight installation, making After the floodlighting equipment is installed, the light is not visible, to maintain the integrity of the building facade.
