For the building lighting project with good effect, the perfect lighting design scheme is the foundation, but it is the most important thing to fully express the effect in the scheme. Then, how to meet the needs of the owners to the greatest extent, show the characteristics of the building to the greatest extent, and increase the charm of the night view of the building? This requires comprehensive consideration from the selection of light sources, the ratio of illuminance values, the selection of lamps and their quantity. Below, the designer will share some experience during the implementation of the building's external wall lighting project.
1. Different building styles use different lighting methods
Building body lighting project has different lighting effects due to different building body styles. For tall and majestic buildings, the lighting and rendering should be evenly divided. The use of plain lighting techniques allows people to reflect the tall and majestic buildings from any point of view in terms of sensory effects; for thin and short buildings, the opposite is true. It is necessary to start from the part, focus on embellishment, adopt lively expression techniques, and cover its thin and short congenital shortcomings with the gorgeousness and dynamic dazzling of local colors... All lighting techniques are inseparable from surface, line, point, movement, These expressions of static, and the lighting design of the external wall of the building are nothing more than these expressions, but the style of the building is different, and the lighting performance methods are also very different. The ultimate goal is to better highlight the night scene effect of the building.
2. Choose different light sources according to the color of the outer wall of the building
The choice of light source for the building body lighting project should be comprehensively considered in terms of light color, color rendering, efficiency, and life. The light color has a lot to do with the color of the exterior wall material of the building. Under normal circumstances, bricks and yellowish-brown stone are more suitable to be illuminated with warm light. Warm color should be the main color, which is formed by the cool color of the building in the night. The sharp color difference makes the outline of the building more obvious. At the same time, the warm color has a wide light field, which makes the building exterior expand.
3. According to the surrounding environment of the building, choose different illuminance values
The required illuminance of the building lighting project mainly depends on the brightness of the surrounding environment and the color of the wall material of the building. The illuminance value is generally for the main facade and the secondary facade. Under normal circumstances, the illuminance of the secondary facade is half of the illuminance value of the main facade, and the three-dimensional sense of the building is expressed through the difference in brightness between the main facade and the secondary facade. At the same time, it is necessary to pay attention to the contrast between the lighting of the building and the surrounding environment, and proper brightness contrast can reflect the best lighting effect of the building.
4. Calculate the number of lamps used according to the illuminance
According to the selected LED light source, the height of the building, and the installation position of the lamps to achieve the required illuminance, the number of LED lighting lamps required is finally determined according to the illuminance. The number of lamps is too large and dense, which not only increases the cost, It is more likely to cause the adverse effect of glare. On the contrary, if the number of lamps is too small, the illuminance cannot meet the requirements, and it does not reflect the characteristics of the building.
5. According to the height of the building, choose the right LED lamps
The height of the building body is different, and the layout and projection requirements of the lamps are also different. Generally speaking, the square projection light has a larger distribution angle and a shorter projection distance. It is suitable for low-rise buildings with fewer floors and round lamps. The angle is smaller and the projection distance is longer. It is suitable for high-rise buildings with many floors. Wide-angle lamps have a more uniform effect, but are not suitable for long-distance projection; narrow-angle lamps are suitable for long-distance projection, but have poor uniformity when used at close distances.
In short, the building lighting project uses light projection to outline the outline of the building, but the actual effect cannot achieve the same effect as during the day. How to fully express the effect in the design plan to show the building to the greatest extent Physical is the real purpose of the lighting project on the outer wall of the building.
