Building profile lighting is to outline the outline of a building directly with a line light source, and to illuminate the edge of a building with a narrow beam can also play a role in outlining the outline. This method is mostly suitable for buildings with unique shapes, highlighting the special geometry of the building under the landscape with low brightness requirements.

Contour lighting usually uses a lot of colored light, which will cover the color of the building itself, but also make it difficult to recognize the building materials and see the structure of the building itself. At the same time, it will make the building itself lose its essence, make the building appear vulgar, and cannot highlight its own characteristics, thus losing the beauty of the building in the whole space.

Combined with the building structure, the use of building local arc and other structures, or the use of disorderly lighting, subvert the dull outline of the hook, and create a scene lighting consistent with the positioning of the building. In the process of local use, the brightness of the linear lamps of the municipal lighting engineering company should be controlled to match the brightness of the night scene lighting in other parts, increase the three-dimensional sense, and use color light cautiously to avoid affecting the design effect of other lighting methods such as cast light. In addition, the design, construction, and owner units should pay attention to the impact of the quality of the lamps, and preferably choose high-quality linear profile lamps.

In order to ensure the quality of urban nightscape lighting projects, lighting design should not be simple and easy to install, scientific lighting design should be introduced, and linear contour lighting should be used with caution.

The use of linear lamps of urban lighting manufacturers should follow the principle of small range and fun, and the local use of buildings (groups) should avoid a large range of simple stacking; Combined with the building structure, the use of building local arc and other structures, or the use of disorderly lighting, subvert the dull outline of the hook, and create a scene lighting consistent with the positioning of the building.
