The innovation of our design lies in its shape and the significance of its shape. Beijing Swift is a bird that often lives under the eaves of traditional buildings. In recent years, Beijing's modernization has developed more and more rapidly, which inevitably brings damage to traditional buildings, causing Beijing Swift to almost disappear from public view, until these years, the country began to focus on the popularization and development of Chinese traditional culture, and rebuilt and restored many ancient buildings. The swift seems to have returned to the public view. We take the swift back to the nest as the theme, mainly to express the restoration and protection of traditional buildings. For the image of the lamp body, we choose the traditional eaves image of the roof, and carry out artistic deformation, so that the whole image has both traditional elements and modern style, and there will be no disobedient feeling when placed indoors. At the same time, we imitate the life traces of swifts and take the swifts in the nest and on the roof as luminous bodies, adding flexibility and interest to the whole work. The light effect is soft divergence, no matter when the observation will show a warm picture effect, at the same time, this warm effect is consistent with the warm image of the swift returning to the nest, so that the lamp body and the indoor environment are integrated into a beautiful picture from any angle, and the traditional Chinese elements are integrated into the modern home, so as to achieve a balance between time and visual concept. Material selection: In the works we designed, Swift is actually a lighting lamp, which can play a role in lighting the interior. This lighting lamp is a solar energy-saving lamp. The solar lamp has the advantages of green environmental protection, high efficiency and energy saving, high quality, high brightness, long life, high intelligence, high safety, high convenience, etc., and plays a role in saving energy and reducing pollution. The material used for the overall structure is degradable wheat fiber plastic. Wheat fiber plastic is a new type of green biological material composed of wheat straw and polymer resin through a special process. It is a new environmental protection building material. This work not only maintains the traditional eaves structure, but also adds modern deformation, which reflects the integration of ancient and modern architectural decoration. We adopt energy-saving and environmental protection new building materials, and strongly support the sustainable development strategy of new energy advocated by the state. At the same time, it also reflects the concept of modern restoration, innovates on the basis of protecting traditional culture, so as to make the works more distinctive and cultural inheritance.
