[0002] With the development of urban construction, the night scene lighting of buildings has become the main body of urban decorative lighting. Using lights to shape the night image of buildings is a kind of beautiful re-creation; the basic purpose of night scene lighting is to focus on the key points and highlight the soul of the building. According to the building type of this project, it is a residential building, so in principle, the facade is not floodlit to avoid adverse effects on residents' lives. However, considering the night scene effect of the entire urban area, appropriate floodlighting is applied to the top of the residence without affecting the lives of residents to create a warm living atmosphere. At the same time, a new generation of lighting is also adopted, using low power consumption on the facade of the building, and using light strips to outline the building frame between the wall seams can better reflect the beauty of the building shape. In the specific process of installing the light strips, when the light strips are arranged around the balcony or other protruding structures on the facade of the building, it is involved to bend the light strips. After the light strips in the bent state are fixed on the facade of the building wall, they are prone to loosening and peeling off, affecting the installation quality and lighting effect of the light strips. Such problems are more prominent at the inner corners where the three directions of the building's exterior wall, balcony edge and roof edge intersect. There is a lack of a unified positioning method for the light strips in multiple intersections, and there are no fixing components that can adapt to the convex and concave shapes around the eaves of the building. As a result, the light strips at the intersection of the three directions are bent widely and are easy to fall off.
