Brief description of the facade lighting design of the building

(Guangxi Urban and Rural Planning and Design Institute, Nanning 530022, Guangxi) Full consideration of the mutual influence of various factors such as the light characteristics of the floodlight, the distribution of light, the color of light, and the installation position of the floodlight.

Keyword light source average illumination facade lighting - With the promotion and implementation of the urban lighting project, the urban road has not only become brighter but also beautiful, and the buildings on both sides of the road are also rendered by various floodlights and neon lights. Eye-catching, showing a style that has not been seen during the day.

To do the design of the outdoor façade lighting of a building, we must first understand the characteristics of the building and the architectural style and artistic concept of the façade. The light-emitting lighting building or building shines in the night sky, just like the outside of the object. Background, the greater the ratio of the grayscale of the building to the grayscale of the background, the more obvious the outline of the building is. The design of the building facade lighting not only can see the outline of the building, but also the selection of lighting fixtures. On top, makes the building look colorful at night.

Selection of Light Source and Illumination Sources of light-emitting illumination In recent years, halogen lamps have been used, and high-pressure sodium lamps with high luminous efficiency, mercury lamps with a light color close to white, xenon lamps, etc., have been widely used because of their low power and high illumination. The use of floodlighting can better highlight the characteristics of the building, with strong stereoscopic effect and good lighting effect. The color of floodlighting changes due to the nature of the building. For example, the lighting of a comprehensive office building, teaching building, library, etc. should reflect a "quiet" character, orange or white light quietly flowing around the building; theater Hotels and entertainment venues must strive to create a lively atmosphere, with bright, lively lights such as pink, purple, and dynamic neon lights to attract pedestrians; the government department's architecture emphasizes sacred and solemn. In the past, the outdoor lighting of buildings used to install lanterns (that is, string lights) along the outline of the building. This method is simple and easy, not only difficult to reflect the three-dimensional sense of the building, but also consumes a large amount of electricity. This method is often used for some part of the building lighting, plus the gorgeous color of the lanterns, it can play a finishing touch.

The illuminance required for the façade illumination shall be determined by the reflectivity of the wall material of the building and the surrounding brightness conditions. The illumination of the same luminous flux will produce different brightness when projected onto the wall of different reflectivity. In order to form a certain brightness contrast, it is necessary to consider the surrounding environment in the design. If the wall surface is not clean and the dirt is too much, the illuminance should be properly raised; if the surrounding background is dark, only a small amount of light can make the building brightness exceed the background; for example, the building interior lighting adjacent to the object being illuminated The lights are on at night, and more light is needed to get the desired contrast.

Facade lighting design For square or rectangular buildings, the diagnosis of the two phases of the building should be made. Thus, different diagnoses can be performed quickly and promptly by experts. Diagnostic results can help troubleshoot problems quickly.

On the other hand, the remote diagnosis mode enables multiple diagnostic sites to be connected to the same diagnostic center, so that the diagnostic program and the fault diagnosis database are independent of each other, so that the patient to be diagnosed and the diagnostic party can share each other's test data and can also share Each other's fault data, analysis methods, diagnostic knowledge and up-to-date information form a truly open system. Through this kind of resource sharing, it is also possible to strengthen the expert's ability to discriminate faults and improve the troubleshooting rate. At the same time, it also enhances the understanding and vigilance of high-risk and prone to the situation, and takes a step forward in preventing failures.

According to the oilfield feedback information that has been piloted in China, the development of remote diagnosis requires technical support such as computer network and detection software, but in some areas, such as remote diagnosis of rod pump wells, China has already achieved Certain progress has been made and is being further strengthened.

4. Remote diagnosis in the development of oilfield fault detection The application of network technology to oil well fault diagnosis is the direction of current major oilfield institutional reforms. It not only provides various technical support for oil production sites, but also provides relevant fields for the petroleum industry. A technical sample. Through the use of the remote fault diagnosis system, it is possible to share the fault data of the site and other reservoir data, effectively strengthen the technical cooperation between the oilfield and the scientific research unit, and accurately grasp the working condition of the oil production well, promptly eliminate the fault of the oil production well, and ensure the oil well. Stable production, production, reducing unnecessary equipment maintenance and reducing costs. The most important thing is that the remote diagnosis technology makes the oilfield farewell to the status quo because the coverage is large and the fault detection is difficult to be timely and accurate. It is the primary support for the future entry of the oilfield into modern information management.
