Glass curtain wall is a beautiful and novel way of building wall decoration, which is a remarkable feature of the era of modern high-rise buildings. As a contemporary new wall, it organically unifies the factors such as architectural aesthetics, architectural function, architectural energy conservation and architectural structure. The buildings show different colors from different angles, and give people dynamic beauty with the changes of sunshine, moonlight and lighting.
High rise building is a necessary building for commercial center, downtown street and landmark. Make the high-rise building have the display function, which can effectively increase the beauty of the building itself, set off the surrounding prosperous atmosphere, improve the eye attraction of the building itself and the commercial subjects in the building, achieve the function of publicity and dissemination of information through the display, and increase the advertising revenue for advertising communication.
At present, there are mainly several kinds of large-area display for buildings: 1. Laser projection; 2. LED light bar lighting; 3. LED outdoor grille screen; 4. LED indoor transparent screen.
For laser projection, because the brightness is not high, it is mostly used at night, and multiple sets are required, with high cost. At present, it is relatively less used.
The biggest defect of LED lighting light bar is that the spacing between light bars is too large, the display brightness is not high and the definition is low. General applications play dynamic lines. However, some landmark buildings with large area and long viewing distance can be used at night. This way can reduce the cost, which is generally used in TV towers or super high-rise buildings.
Laser projection and LED light bar lighting, due to low brightness, low definition and low market utilization.
LED outdoor grille and LED indoor transparent screen are the most commonly used methods of glass curtain wall display at present. The following mainly introduces these two. In particular, LED indoor transparent screen in this paper is a general term for indoor transparent display. It is more subdivided and has a variety of design methods. It will be introduced in detail in other articles according to the characteristics and differences of subdivided products.
The general requirement for glass curtain wall is not to affect the indoor lighting, beautiful appearance, not to affect the overall shape of the building, and meet the viewing requirements at the same time. The design of LED outdoor grille and LED indoor transparent screen adopts the hollowed out design method of light strip. The product itself has the characteristics of light transmittance, ventilation and light weight. Therefore, generally speaking, they all belong to LED transparent screen, which is divided into two different names according to waterproof and non waterproof.
1、 LED outdoor grille
Led grid screen is a kind of transparent screen, which is a display module designed with light bar structure, so it is also called light bar screen. Multiple light strips are spliced to call the display module. The hollowed out between the light strips can ventilate and dissipate heat, and can also pass light, which does not affect the building daylighting. At the same time, it is conducive to reducing wind resistance and reducing the installation of steel structural materials. The light bar is generally made of aluminum profile, which is not only conducive to heat dissipation, but also light and thin overall structure, fast and convenient installation and more beautiful appearance. The inside of the LED light strip is sealed with anti UV potting adhesive. The overall structure is waterproof and dustproof, with IP65 high protection grade; It can be widely used in building curtain wall, building top floor, outdoor lighting advertising, creative sky curtain and other fields. It not only realizes the publicity function of advertising media, but also can be perfectly integrated with buildings, does not damage its original structure and appearance, and is more green and energy-saving.
Modular design, free splicing. Brightness has high brightness and low brightness; The standard size of the product is 1000x500mm. The size can also be customized according to the installation position.
1. Waterproof, dustproof, low temperature, high temperature and humidity resistance, and can be used in various harsh outdoor environments for a long time;
2. The transparency is 40% ~ 90%, with high transparency, which does not affect the indoor lighting and the overall beauty of the building;
3. Aluminum alloy profile design, the screen body is more beautiful, more conducive to heat dissipation, and the product performance is more stable;
4. Ultra thin design, light weight, convenient installation and maintenance, reduce the installation of steel structure and save cost.
5. Optional maintenance before or after the screen increases the adaptability to the installation environment;
2、 LED indoor transparent screen
LED indoor transparent screen, also known as ice screen, transparent screen and led transparent screen; Modular design, free splicing; High permeability and fast installation; Aluminum alloy profile design is more conducive to heat dissipation, lighter weight, convenient installation and maintenance, and saves the cost of steel structure; Ultra thin design, more beautiful after installation. Hoisting, vertical installation, back support and other installation methods can be adopted. Brightness has high and low brightness. The products have standard sizes of 1000X1000mm, 1000x500mm and 500x500mm, and other shapes and sizes can be customized.
1. Transparent design, combined with 3D video materials, makes the display full of vitality and more attractive.
2. The transparency is 40% ~ 90%, with high transparency, which does not affect the indoor lighting and the overall beauty of the building;
3. Aluminum alloy profile design, the screen body is more beautiful, more conducive to heat dissipation, and the product performance is more stable;
4. Module design, free splicing, hoisting and assembly.
5. Ultra thin design, light weight, convenient installation and maintenance, reduce the installation of steel structure and save cost.
6. Optional maintenance before or after the screen increases the adaptability to the installation environment;
According to the characteristics between the two, LED outdoor grille and LED indoor transparent screen have the characteristics of high brightness. The main difference lies in the difference between the installation environment and the beauty of the product itself.
Because the LED indoor transparent screen is used indoors, it will not affect the architectural appearance and keep the original architectural shape unchanged; The spacing can be smaller and the definition is higher. Even if the area is small, the definition can meet the viewing requirements. Indoor installation is adopted, no high-altitude operation is required, and installation and maintenance are more convenient; No waterproof treatment is required, the light strip is lighter and thinner, and the permeability is higher; Lighter weight, glass curtain wall keel structure can be used for installation, which saves cost.
However, due to the design method of glass curtain wall, keel and node support are mostly used behind the glass, so how to avoid keel, node and other structures should be considered for indoor installation. For places with large glass sizes, different display module installation needs to be customized. Therefore, the cost of display equipment is increased to a certain extent.
LED outdoor grille is mainly used outdoors. It adopts waterproof light strip design. Generally, the spacing is large, which is suitable for large area use. Outdoor installation requires high-altitude operation, which increases the difficulty and cost of construction. Waterproof design, which can be installed on the building facade in a large area; The utility model can be used in a large area, the spacing can be large, and the cost can be reduced accordingly. The ventilation of the lamp strip can reduce the wind pressure borne by the screen itself.
In summary, there are few types of glass sizes, no shielding behind the glass, and the display area is small, generally less than 300 square meters. Indoor transparent LED screen can be considered to make the overall effect more beautiful.
When the glass is too large for indoor installation. LED outdoor grille screen can be used.
