News & Announcements

After more than 30 years of rapid development in my country, the building curtain wall has comprehensive performances such as wind resistance, earthquake resistance, watertightness, airtightness, fire protection, lightning protection, energy saving, sound insulation, etc. The requirements have reached a high level of global attention. The architectural curtain wall has also been widely used in a large number of applications due to its outstanding characteristics such as light weight, multi-material, flexible and good shape, independent wide adaptation, stability and high performance.

With the enrichment of social life, people's aesthetic requirements for environmental art and design have increased, and the demand for a good environment for night activities has also become stronger. The sunset is shining, the rigid buildings are replaced with a soft and colorful night exquisite image, and the city also shows another beautiful visual enjoyment to people in the night. The combination of architecture and lighting not only enriches the viewing of the structure, but also enhances the expression of the inner emotional atmosphere of the architectural image.

In urban night landscape buildings, the combination of a large number of carefully designed curtain walls and lighting in coordination with the surrounding environment enriches people’s night life. It is very important for the prosperity of tourism and business economy, the creation of a good cultural atmosphere, and the establishment of the image of the city at night. Significance.

The curtain wall system is an independent and integral whole structure with a certain deformation ability. It is composed of panels and supporting structures. It is usually set on the outside of the main structure. It has a certain displacement ability relative to the main structure and does not bear the force of the main structure. It has a delicate decorative effect. Lightweight wall that is easy to maintain. Its panel usually uses

Glass, metal plates, stone, etc., the supporting structure often uses aluminum alloy beams, columns, steel structures, glass ribs, rigging, etc. According to the structural form, it can be divided into components with mature technology and flexible construction, time-controlled high-precision pre-installation The unit type, the point-supported type with various internal and external transparent forms, the full-glass system with full perspective and three-dimensional levels.

As a rapidly developing new type of green semiconductor lighting source, LED lights have the advantages of high efficiency, energy saving, safety and stability, low carbon and environmental protection, quick response, compact and shockproof.

According to the expression requirements of different architectural shapes, the form of expression of LED lights is still inseparable from the basic spatial elements of "point", "line" and "plane" in geometry.

The form of "points" in space is the most common and flexible, while the arrangement of LED light sources "points" transforms the plane into a three-dimensional representation of alternating light and dark, which is generally realized by LED point lights that independently control signal pixels. The lamps are connected by an integrated non-joint bayonet anti-pull connection, and are designed with high conductivity, weather resistance, low heat, low pressure, and constant current. Various characteristic graphics and gradients can be realized through diversified installation combinations of multiple distribution forms.

The outer contour of the building is usually outlined and presented in the form of LED "line" light source. LED "line" bar lights are still integrated by many point light sources, using aluminum alloy brackets with good heat dissipation and lightweight end caps, and they are weather-resistant and sealed. The waterproof combination forms a reliable fully sealed structure, which can be installed in single or multiple combinations through the automatic addressing function to achieve high saturation monochrome or color, static or dynamic, with high light efficiency and wide viewing angle.

For the highlighted parts of the building, the LED "surface" light source is often used for display, which is realized by large-surface illumination of high-power lamps or floodlight of high-power LED wall washers. At the same time, by controlling the built-in microchip, dynamics such as gradual change, randomness, jumping, color flashing, and alternation can be realized, or effects such as chasing and scanning can be realized by controlling the DMX signal system.

In the past, architectural curtain walls and lighting projects often have unsatisfactory results in the following interactive implementations. It is also a traditional single special project that has done better, but the overall sense of the building, quality control, and user experience will leave many shortcomings, regrets and even hidden dangers The place should attract attention and advance awareness.

3.1 Consistency of the overall appearance effect plan expression

Because the curtain wall project will be equipped with a rich variety of surface materials according to different architectural styles, the emphasis of the architectural humanities and expressions it conveys is also different. When working with lighting, it should be noted that the effects of different surface materials in different colors, different brightness, and different light source expressions are completely different. When the traditional construction sequence is implemented, that is, the lighting project is installed after the curtain wall project is implemented, the overall effect will inevitably be limited. In addition, there are a series of inconsistencies and misunderstandings in concept, design, processing, construction, maintenance, etc. in the cross communication between different types of work, and there are uncertainties that are more sophisticated but not perfectly presented.

3.2 Overall performance consistency of successive installation operations

Because of its complete comprehensive performance, the curtain wall project can be reliably and beautifully presented in various buildings with multiple functional volumes and a large number of complex and simple shapes. Especially with its light skin, the indoor and outdoor environmental spaces are harmoniously coexisted. Functional effects such as density and sound insulation are the user's first touch. In traditional installation, the problems of cross-professional connection, such as the installation of lamp support, component placement and pipeline hole reservation, limitation of operating space, measures for concealed routing of curtain wall profiles, collaborative sealing of uneven interface or flush edges, etc. , It often causes the impact or damage to the waterproof or drainage performance of the entire curtain wall system, and even more serious damage to the force transmission components of the curtain wall, the system stability and safety will bring no small hidden dangers.

3.3 Cross-implementation of quality control management for accessory components

In the traditional implementation process, the curtain wall and lighting components involve a series of cross-cutting issues such as overall shading, ventilation, cleaning, etc., and the external lamps are hidden but need to accommodate an appropriate amount of angle adjustment, the anti-glare equipment is firmly connected, and the lighting control is reasonable through the wiring. The overall and single product quality control requirements must reach a certain level to avoid later rework. Especially for key projects and super high-rise buildings, the occurrence of accidents will not only pay the cost of weight-bearing remedial measures, but also cause greater safety risks to the people around the building, and the building’s own operating image cannot compensate for the loss of reputation.

The integration of building curtain wall lighting refers to the determination of the initial plan, simultaneous selection of curtain wall system and lighting performance, comprehensive testing, unified comprehensive evaluation and perfection, coordination of processing, assembly and transportation of profile lamps, orderly supply of materials on site, and overall commissioning and maintenance. , Have reached a high level of unanimity and integrity, clearly defined rights and responsibilities, efficient implementation, while avoiding the above drawbacks, but also have a higher functional integrity, such as the combination of advanced technology of curtain wall system factory assembly, in predictability and timeliness There will be greater comprehensive advantages in terms of performance, economy, and safety.

5.1 Different types of buildings have different emphasis on performance

For example, in the design of high-end hotel projects, the building curtain walls often use high-end textured natural stone and transparent and tall glass panels. The integrity of the light environment shaping and the consistency of the hotel brand color temperature should be emphasized, and the function and decoration should be combined. Either warm, quiet, or eye-catching and gorgeous, the highlights and key points of the hotel elements are highlighted through color lighting and local lighting. With the expansion and enrichment of the visual space, the best temperament atmosphere is presented to the guests. The design of the resort hotel should grasp the integration of the main body of the building with nature and the local cultural landscape. Through the rational use of lighting, the romantic and elegant scenery and the calm and relaxing mood are naturally combined to achieve the lighting for mountains, waters and buildings. The ingenious decoration of the hotel is naturally natural, creating a better spiritual atmosphere experience and realizing the effective improvement of the hotel's cultural taste.

In commercial office buildings with a relatively large building type, the building curtain walls generally adopt simple and capable straight lines, and the lighting settings will also be designed in a certain arrangement law, orderly, to ensure the purity and simplicity of the main body of the building, and the professional and stable atmosphere environment requirements . The use of color temperature changes to present an elegant level conversion, mainly based on warm colors, comfortable and non-glare settings, and emphasizes the spatial structure characteristics and design connotation of office buildings, and creates a modern, simple and exquisite building night image, which has become an active urban landscape An indispensable part of.

As a city landmark, the super high-rise building is a visual center that reflects the rich landscape value and architectural characteristics of a city. Its curtain wall and lighting design must fit the city's positioning. Through artistic expression methods such as dotted lines, movement and static, cooling and heating, it can emphasize the architectural personality, use local colored lighting to create dynamic lighting effects, highlight the performance of architectural details, and organically integrate super high-rise landmark buildings with surrounding landscape lighting to create distinctive features The city’s skyline, which collectively reflects the intention of the city, makes the structures more colorful and endless charm, and creates more social benefits.

In the integrated design of municipal buildings, the coordination of the curtain wall and lighting scheme should focus on showing the solemnity of the main body of the building. The choice of curtain wall system is mainly based on a stable and thick light-colored dry hanging stone system, and transparent, clean, bright and capable glass. The curtain wall system, the reliable performance of the door and window curtain wall system with the square shape and the aluminum curtain wall system with the flat texture of the local decoration, mainly use white or yellow as the main color. The bottom-up fading effect makes the structure look taller and taller. A sense of unity, uplifting, generous and solemn atmosphere.

In the design of stadiums, the main body of the building is often unique in style, with large undulations and irregular shapes. The facade of the curtain wall is often made of steel structure as the supporting framework and covered with metal panels. The focus of the lighting design in the distance should mainly highlight the overall outline of the building's height, width and grandeur; the close-up design should be based on the sports elements and design concepts of the exhibition site; between the ceiling and adjacent venues, the contrast of illuminance and color can be used The change presents a dynamic sense of rhythm and rhythm, and a clear sense of hierarchy between the subject and the environment; it highlights the comfortable, sporty, and humanistic vitality of the venue.

Compared with dynamic stadiums, residential buildings seem to be more warm and calm. Natural stone curtain walls or imitation stone spraying, door and window systems with better performance are often used, and their lighting design often uses warm yellow tones to render a warm atmosphere of life. The top lighting design of the building uses warm white light to emphasize the three-dimensional sense of the structure's undulations, and the outer contours are often densely arranged with point light sources to highlight the sense of volume. The stairwell and the outside air-conditioning stand are brightened with low color temperature, reflecting the sense of architectural sequence. Lighting lighting should also be restrained to avoid glare and light pollution affecting the normal life of residents.

5.2 Build a green and livable city to prevent light pollution

Reasonable architectural curtain wall lighting design can not only embellish or enhance the architectural art, spatial layout, and comfortable environment, but also exquisitely reflect the taste of the city, and also adjust the mood and environmental atmosphere of the audience. However, excessive or unreasonable design will affect people's vision, cause irritation and visual fatigue, and make people uncomfortable. Buildings and light have different feelings on people. Direct glare should be avoided in the design. It is recommended to install anti-glare equipment to ensure the soft effect of indirect reflection at any viewing angle, reduce light pollution, and create a harmonious and suitable light environment. Therefore, in the initial stage of integrated design, simulation and theoretical calculation of lighting levels, light colors, illuminance, lighting methods, etc. should be carried out. Conditional recommendations for model testing and debugging, continuous improvement of the plan, and debugging the best and reasonable lighting effect .

5.3 In the selection of lamps, it is recommended to use high protection level

In the selection of lamps, not only should choose energy-saving and environmentally friendly light sources, but also new light sources with the principles of long life, high luminous efficiency and high safety factor. The appropriate light distribution angle should be selected through illuminance analysis to fully improve the utilization rate. The parts that are more difficult to maintain should be selected for ultra-long life LED light sources. With the rapid development of science and technology, lighting products and intelligent control equipment are becoming more abundant. From the overall operation and maintenance cost combined with the analysis of past engineering experience, it is recommended to give priority to equipment with high protection level to reduce daily maintenance and resource saving.

The curtain wall is the gorgeous coat of the building. Its solemn or graceful form gives the building a more expressive temperament, while the light reflects the charm and connotation of the protagonist in the night more vividly.

Watch the curtain wall during the day and the lights at night! I hope that the cultural tension and shaping skills of architectural art can slowly infiltrate and spread in the vigorous humanistic ecology.
