Decorative floodlighting City's public lighting will include one or more of three interdependent factors: full functional lighting, landscaping lighting, and lighting designed to achieve an atmosphere. Until now, many cities have only provided functional lighting for the safety of passengers and pedestrians, and few have been designed to attract tourists after dark. Fortunately, people are increasingly interested in outdoor lighting that enhances the landscaping of the city. Walking into a well-designed square or a building or sculpture decorated with floodlights, we are likely to marvel at the importance of the atmosphere and the extraordinary ability to display features and forms.
Floodlighting technology is not based on the principles of lighting engineering; the perception and insight of aesthetic value is the most important.
During the day, objects are either directly illuminated by daylight or by diffuse light from the sky or both. The effect is that all features are emphasized by the constant interaction between continuous light and shadow. It is impossible and unrealistic to achieve this effect through artificial lighting. The key to the problem is to determine which feature is the most attractive and to enhance its effect through lighting. Once the lighting requirements have been determined, a realistic assessment of the location, source type, and power of the fixtures that meet the design goals can be made.
Direction of viewing
Surveying the venue during the day can determine the primary viewing position and viewing direction for a particular target. After that, the lighting effect of the viewing direction should be optimized to avoid the interference of light. Also note the relative importance of each viewing angle in order to establish different levels of emphasis in lighting design.
Floodlighting placement
In the past, floodlighting was often placed at a distance from the object being illuminated. Other alternatives are: on the roof next door, on the bracket mounted on the front of the building, on the open ground, on the ground behind the low wall, in the flowerbed or shrub. But the current trend is to bring the floodlighting system as close as possible. The reasons are:
1. The lighting effect is not limited to the plane and is more significant.
2, can reduce the glare of people walking around the object.
3. It is not necessary to install the floodlighting system on a house or building that is not in its own right.
4. Reduce spillage. The more light that is projected by floodlighting (ie, within the distance from the object being illuminated), the more light that spills into the surrounding environment (typically 30% for high power projection).
The detailed lighting of the facade of the building requires careful study of its structure and its connotations. The placement of the floodlighting system requires careful selection, and the shape, color and size of the building illuminated by floodlighting cannot be too different from the building during the day.
Environment and background
If the environment and background of the object are dark, a relatively small amount of illumination can highlight the object. In addition, if there are other buildings in the adjacent area, the windows will reflect a strong brightness, and in order to achieve the contrast effect, more illumination of the illuminated object is required. The same is true if we are looking at the object against a very bright background. In both cases, color contrast is considered to aid or replace brightness contrast.
Synthesis of light
There is no concept of the synthesis of the correct light for the illumination of the illuminated object. The choice of the illuminated element, the color and brightness used depends entirely on the designer's expression. The same is true for dynamic lighting with varying colors and brightness.
Use of color
For color, the world around us is always changing. The time, weather, and season determine how we feel a certain moment in time. Sometimes colored lighting is used to evoke the feeling of a certain daytime environment, which is to achieve the layout of the scene through the night Flood Lighting project. Temperature also has a lot to do with color: warm light means heat, and blue light gives a cold feeling.
