How to choose a led mesh screen for building lighting? Resolution and installation core skills: Firstly, we need to clarify a core understanding: the "usability" of building lighting grid screens is far more important than "aesthetics". The term 'easy to use' here refers to the resolution adapting to building scenes, installation fitting to building structures, protective performance adapting to outdoor environments, convenient operation and maintenance, and controllable costs; And 'good-looking' is a visual presentation based on 'easy to use'. Many customers blindly demand the "highest resolution" from the beginning, but ignore the height, viewing distance, and structural characteristics of their own buildings. This not only increases procurement costs, but may also lead to chaotic night scenes and reduced energy efficiency due to the mismatch between resolution and scene - this is the first core misconception when choosing building lighting led mesh screens.
Core selection of building lighting Mesh screen: first determine the scene, then select the product
The first step in choosing a building lighting grid screen is not to look at parameters or compare prices, but to first clarify one's own lighting scene, because the scene directly determines the resolution, protection level, installation method, and even the later operation and maintenance costs of the grid screen. The demand for grid screens varies greatly among different types of buildings, and blind selection will only backfire. Based on the current mainstream scenarios of building lighting, we can divide the selection scenarios of grid screens into three categories, each with its own emphasis on selection logic.
1. High rise landmark buildings (with a height of over 50 meters)
High rise landmark buildings are the core of urban night scenes, such as office buildings, hotels, cultural and tourism landmarks, etc. The core requirement for lighting of such buildings is "long-distance visual impact", and the viewing distance is usually between 50-200 meters. Therefore, the selection of grid screens focuses on "transparency+long-distance display effect", rather than blindly pursuing high resolution.
In this type of scenario, the key points for selecting the lighting grid screen for the building are: priority should be given to selecting grid screens with larger spacing (conventional P30-P150), with transparency controlled between 60% -80%, which can ensure the integrity and clarity of the image when viewed from a distance, and reduce the obstruction of the building facade, without affecting the beauty and lighting of the building itself. At the same time, high-rise buildings are faced with extreme outdoor environments such as strong wind, rainstorm, and large temperature difference, so the protection level of the grid screen must reach IP65 or above, and have a wind resistant and compression resistant design - it is recommended to choose aluminum alloy frame+high-strength lamp beads, whose frame thickness is not less than 1.2mm, and the lamp beads use waterproof packaging technology to avoid water ingress, degumming, deformation and other problems in long-term outdoor use.
In addition, lighting projects for high-rise buildings usually require synchronous presentation of dynamic images, text, logos, and other content. Therefore, the control system for grid screens also needs to be given special attention, with priority given to systems that support remote control and multi screen linkage, to facilitate later debugging and operation, and reduce the risks of high-altitude work. It should be noted that the selection of grid screens for high-rise buildings is not necessarily better with higher resolution. For example, the grid screens of P10-P20 have high resolution but small spacing and low transparency, which not only increases the procurement cost but also increases the burden on the building. At the same time, when viewed from a distance, the advantages of high resolution cannot be fully realized, and instead, the image becomes too dense, resulting in visual clutter.
2. Mid to low rise commercial buildings (height 20-50 meters)
The core requirement for lighting in mid to low rise commercial buildings, such as street shops, small commercial complexes, apartment buildings, etc., is "close range visual presentation+brand exposure". The viewing distance is usually between 10-50 meters. Therefore, the selection of grid screens focuses on "resolution and image delicacy" while also considering cost control.
In this type of scenario, the selection criteria for building lighting grid screens are: it is recommended to choose a resolution of P16-P30. Grid screens in this range can ensure the delicacy of the image when viewed up close, avoid pixel graininess, and control procurement costs, making them suitable for the lighting budget of mid to low rise buildings. It is recommended to control the transparency between 50% -70%, which can ensure the display effect and avoid excessive impact on the internal lighting of buildings - especially apartment buildings and office buildings, which need to balance the beauty of the building and internal lighting during the day. Excessive transparency will affect the display effect, while insufficient transparency will block the light.
In addition, the lighting of mid to low rise commercial buildings usually requires frequent switching of images and updating of brand information. Therefore, the response speed and compatibility of grid screens also need to be carefully considered. It is recommended to choose products with a response speed of ≤ 10ms and support for multiple playback formats (MP4, JPG, GIF, etc.) to facilitate flexible content updates in the later stage. At the same time, the installation height of such buildings is relatively low, making later operation and maintenance relatively convenient. However, it is still necessary to choose products with a protection level of IP65 or above to avoid rainwater and dust from entering the equipment and affecting its service life. For customers with limited budgets, they can prioritize the cost-effective conventional grid screen, without blindly pursuing high-end configurations, as long as it meets the core requirements of resolution and protection level.
3. Alien buildings (curved, curved, irregular shapes)
The core requirement for lighting of irregular buildings, such as cultural venues, art centers, and characteristic residences, is to "fit the architectural shape+customize the display effect". The exterior of these buildings is irregular, and conventional flat grid screens cannot adapt. Therefore, flexible grid screens need to be selected, which is also the core selection point for lighting of irregular buildings.
In such scenarios, the selection criteria for building lighting grid screens are: priority should be given to flexible grid screens, which have the characteristics of being bendable and foldable, with a bending angle of 0-180 °, and can perfectly fit irregular building facades such as arcs and curves, without problems such as image breaks or obvious stitching marks. In terms of resolution, it needs to be flexibly selected according to the shape of the building and the viewing distance. The general recommendation is P20-P40. If the building shape is complex and the viewing distance is close, the resolution can be appropriately increased to P16-P20 to ensure the delicacy of the image; If the viewing distance is far, you can choose P30-P40 to control costs while ensuring long-distance visual effects.
In addition, the lighting of irregular buildings usually requires customized sizes and specifications. Therefore, when choosing a grid screen, it is necessary to communicate with the manufacturer in advance, provide detailed dimensions and design drawings of the building, and allow the manufacturer to customize a flexible grid screen that is suitable to avoid problems such as size mismatch and inability to install. At the same time, the protection level and durability of the flexible grid screen also need to be focused. It is recommended to select waterproof, anti-corrosion and anti-aging flexible lamp beads and frames to ensure that long-term outdoor use will not cause damage, aging and other problems. In addition, the installation difficulty of irregular buildings is relatively high, so the weight of the grid screen also needs to be controlled. Lightweight products should be prioritized to reduce the weight of the building and lower installation risks.
Resolution adaptation core skill: Do not blindly chase high, fitting the scene is the key
Resolution is one of the core parameters of building lighting grid screens, which directly determines the delicacy of the night view display effect. However, many customers often fall into the misconception of "the higher the resolution, the better" when choosing, thinking that high resolution will definitely present better results. In fact, the core of the resolution selection for grid screens is "fitting the viewing distance+building scene". Different viewing distances and building heights correspond to completely different resolutions. Blindly pursuing high resolution will only increase procurement and operation costs, and even affect the lighting effect.
Below, we will combine "viewing distance" and "building height" to analyze the scientific adaptation methods of resolution, and share common misconceptions in resolution selection to help you accurately match the most suitable flexible grid screen resolution.
1. Core adaptation formula for resolution and viewing distance
The resolution of the building lighting grid screen is essentially the "pixel spacing" (i.e. the distance between adjacent light beads, measured in millimeters). The smaller the pixel spacing, the higher the resolution and the finer the image, but the higher the procurement cost; The larger the pixel spacing, the lower the resolution, and the more pronounced the graininess of the image, but the lower the procurement cost, the better the transparency. The adaptation logic of the two can be calculated through a simple formula: optimal viewing distance=pixel spacing x 1000 (unit: mm).
For example, a grid screen with a pixel pitch of P30 has an optimal viewing distance of 30 × 1000=30000mm=30 meters. This means that when the viewing distance is around 30 meters, the P30 grid screen can present a clear and complete image without obvious pixel graininess; If the viewing distance is less than 30 meters, such as 20 meters, the P30 grid screen will have a noticeable pixel graininess, which affects the visual effect; If the viewing distance is greater than 30 meters, such as 50 meters, the grid screen of P30 will appear blurry and unable to present clear details.
Based on this formula, we can accurately match the resolution according to our own viewing distance. The specific adaptation reference is as follows (combined with mainstream building lighting scenes):
-Viewing distance of 10-20 meters (for mid to low rise commercial buildings and street shops): compatible with P16-P20 grid screen, pixel spacing of 16-20mm, delicate picture, no obvious graininess, suitable for close viewing, while considering cost;
-Viewing distance of 20-50 meters (for medium to high-rise buildings and small landmarks): compatible with P20-P30 grid screen, with a pixel spacing of 20-30mm, which can ensure image clarity and control procurement costs. It is currently the mainstream resolution for building lighting;
-Viewing distance of 50-100 meters (high-rise landmarks, large-span venues): compatible with P30-P40 grid screen, pixel spacing of 30-40mm, good transparency, complete viewing from a distance, no need to pursue high resolution;
-Viewing distance of over 100 meters (super high-rise landmarks, urban skyline buildings): compatible with P40-P60 grid screen, pixel spacing of 40-60mm, focusing on ensuring visual impact from a long distance. High resolution has no practical significance and instead increases costs.
It should be noted that this formula is only a basic reference, and in actual selection, it needs to be flexibly adjusted based on factors such as the height of the building, the material of the exterior facade, and the lighting content. For example, if the exterior of a building is made of light colored materials (such as glass or stone) with strong light reflection, the resolution can be appropriately reduced to avoid the image being too dazzling; If the lighting content is mainly dynamic videos and delicate patterns, the resolution can be appropriately increased to ensure the details of the picture; If the content is highlighted in text LOGO, Simple patterns are the main focus, which can reduce resolution and control costs.
2. Three common misconceptions about resolution selection, avoiding them to save costs and improve results
Misconception 1: The higher the resolution, the better the effect. This is the most common misconception, as many customers believe that as long as they choose the highest resolution grid screen, they can present the best night scene effect. However, in reality, if the resolution is too high and the viewing distance does not match, not only will the advantages of high resolution not be reflected, but two problems will also arise: first, the procurement cost will increase significantly, and the price of high-resolution grid screens is 1.5-2 times that of conventional resolutions; The second issue is a decrease in transparency. The smaller the pixel spacing and the higher the density of light beads, the worse the transparency, which can obstruct the exterior facade of the building and affect its daytime aesthetics and internal lighting. For example, in mid to low rise commercial buildings with a viewing distance of only 15 meters, if you choose a high-resolution grid screen with P10, although the image is delicate, the procurement cost increases, and the transparency is low, blocking the light, which is not worth the loss.
Misconception 2: All buildings use a uniform resolution. Buildings of different heights, shapes, and viewing distances have completely different requirements for resolution. Blindly unifying resolution will only result in some areas not meeting expectations. For example, within the same commercial complex, the lower level area facing the street has a closer viewing distance and is suitable for resolutions ranging from P16 to P20; The viewing distance in the high-rise area is far, suitable for resolutions of P20-P30. If the resolution of P20 is uniformly selected, the graininess of the low-level area image is not obvious, while the high-level area image is clear, which can ensure the overall effect and control costs; If the resolution of P16 is uniformly selected, the advantage of high resolution in high-level areas cannot be reflected, and it will also increase procurement costs.
Misconception 3: Neglecting the adaptation of resolution and control system. Many customers only focus on the resolution of the grid screen, but ignore the adaptability of the control system, resulting in problems such as image lag, ghosting, and inability to play synchronously in the later stage. For example, high-resolution grid screens (P16 and below) have higher requirements for control systems, and high-performance control systems need to be selected to ensure the smoothness of the image; If the performance of the control system is insufficient, even if a high-resolution grid screen is selected, problems such as image lag and ghosting may occur, affecting the lighting effect. Therefore, while selecting the resolution, it is necessary to synchronously confirm the performance of the control system to ensure compatibility between the two.
3. Adaptation skills for resolution and lighting content
In addition to viewing distance and building height, lighting content also affects the choice of resolution. Different lighting content has different requirements for resolution, and precise adaptation is necessary to present the best effect:
If the lighting content mainly consists of "text, logos, and simple patterns" (such as corporate logos in office buildings and promotional text in street shops), there is no need for high resolution. Choosing P100-P150 can ensure the clarity of text and logos while controlling costs; If the lighting content mainly focuses on "dynamic videos, delicate patterns, and gradient colors" (such as night scenery shows in cultural and tourism landmarks and art centers), it is necessary to choose a higher resolution grid screen (P30-P55) to ensure the delicacy of the picture and the naturalness of color transitions, avoiding problems such as image segmentation and color distortion; If the lighting content mainly focuses on "large-area color blocks and dynamic flowing effects" (such as contour lighting of residential buildings and industrial parks), a lower resolution grid screen (P62.5-P80) can be selected to ensure color uniformity and smooth dynamic effects, without pursuing fine details in the picture.
Core Techniques for Installing Building Lighting Grid Screens: Safety First, Adapting to Buildings, and Balancing Aesthetics
If resolution is the "core soul" of building lighting grid screens, then installation is the "foundation of standing". The core reason why many lighting projects experience frequent failures, unsatisfactory results, and even safety hazards in the later stage is that the installation is not standardized and does not conform to the building structure. The core principle of installing a grid screen for building lighting is "safety first, adaptable to the building, aesthetically pleasing, and easy to maintain". Especially for outdoor building lighting, facing extreme environments such as wind, rain, and sun exposure, the standardization of installation directly determines the service life and operational stability of the grid screen.
Combined with years of practical experience in outdoor building lighting installation, we will disassemble and install core skills from three dimensions of "preparation before installation, core steps during installation, and commissioning and acceptance after installation", and share common mistakes in the installation process to help you build a safe, durable and beautiful building lighting project.
1. Preparation before installation: Do 3 things well to avoid rework in the later stage
The preparation work before installation is the key to ensuring smooth installation and avoiding rework in the later stage. Many customers and engineering companies often neglect the preparation before installation, resulting in problems such as size discrepancies, missing accessories, and structural incompatibility during the installation process. This not only increases construction costs but also delays the project schedule. Before installation, it is important to focus on the following three things:
(1) Accurately survey building structures and customize installation plans
Firstly, it is necessary to conduct a precise survey of the building facade, measuring the height, width, facade material, and structural characteristics (such as whether it is curved or curved, and whether there are protruding parts). At the same time, the load-bearing capacity of the building must be confirmed - especially for high-rise buildings and irregular buildings, it is necessary to confirm the load-bearing capacity of the building facade to avoid safety hazards caused by insufficient load-bearing after the installation of the grid screen. For example, in glass curtain wall buildings, it is necessary to confirm the load-bearing capacity of the glass to avoid damaging it during installation; Curved buildings require precise measurement of bending angles and customized installation brackets.
After the survey is completed, a detailed installation plan should be developed based on the specifications, resolution, and transparency of the grid screen, specifying the installation position, installation height, bracket type, fixing method, wiring path, etc. At the same time, the key and difficult points during the construction process (such as high-altitude operations and installation in abnormal areas) should be marked, and countermeasures should be formulated in advance. For irregular and high-rise buildings, it is recommended to invite professional installation teams and structural engineers to conduct on-site inspections to ensure the safety and feasibility of the installation plan.
(2) Check the led grid screen products and accessories to ensure compatibility
Before installation, a comprehensive inspection of the purchased building lighting grid screen, fixed accessories, control system, etc. is required to confirm whether the product quality and specifications meet the installation requirements, and to avoid problems such as product damage, size discrepancies, and missing accessories. The specific inspection points are as follows:
-Grid screen: Check whether the light beads are intact, whether there is damage, whether the frame is deformed, whether the waterproof packaging is in place, conduct power on testing to confirm whether the display effect, color uniformity, and response speed are normal;
-Fixed accessories: Check the quantity and quality of butterfly clips, network cables, and other accessories to ensure that they are complete, durable, and suitable for outdoor use
-Control system: Check the quality of the controller, signal lines, and power lines, confirm that the control system is compatible with the grid screen, conduct power on testing, confirm that the control function is normal, and can achieve remote control and multi screen linkage.
(3) Ensure safety protection and on-site layout
The installation of building lighting grid screens mostly involves high-altitude operations, and safety protection is crucial. Before installation, it is necessary to arrange the site, set up safety warning signs and protective fences, and prohibit unrelated personnel from entering the construction area; High altitude workers must wear safety belts and helmets, and be equipped with high-altitude work platforms (such as scaffolding and high-altitude work vehicles) to ensure construction safety. At the same time, it is necessary to check the safety of construction tools, such as drills, wrenches, screwdrivers, etc., to ensure that the tools are in good condition and avoid tool failures during the construction process, which may cause safety hazards. In addition, if the construction area involves traffic arteries, it is necessary to communicate with relevant departments in advance, do a good job in traffic diversion, and avoid affecting traffic order.
2. Core steps in installation: standardize operation, control details
During the installation process, it is necessary to strictly follow the installation plan, focusing on the three core steps of grid screen splicing, wiring, and waterproof treatment. Each step should be operated in a standardized manner to avoid details that may affect installation quality and later use.
(1) LED mesh dipaly screen splicing: flat alignment
The quality of grid screen splicing directly determines the display effect of night scenes. If the splicing is not smooth, it will cause image discontinuity and obvious splicing traces, affecting visual aesthetics. During the splicing process, it is important to focus on the following key points:
Before splicing, it is necessary to adjust the flatness of the LED mesh display to ensure that the surface of the bracket is flat, without protrusions or depressions, to avoid misalignment of the grid screen splicing caused by uneven brackets; When splicing, adjust the position of the grid screen to ensure that the edges of adjacent grid screens are aligned without obvious misalignment or protrusions; For flexible grid screens, when splicing, it is necessary to conform to the architectural shape, avoid forcibly pulling or bending, and prevent damage to the light beads and wiring of the grid screen.
After the splicing is completed, it is necessary to inspect the flatness and splicing gaps of the grid screen as a whole. If there are problems such as misalignment or excessive gaps, they need to be adjusted in a timely manner; At the same time, check the fixing condition of the grid screen to ensure that each grid screen is firmly fixed to the wall without looseness or shaking. In addition, during the splicing process, attention should be paid to protecting the light beads and lines of the grid screen, avoiding collisions, scratches, and preventing problems such as damage to the light beads and breakage of the lines.
(3) Wiring: Standardized and orderly, well done waterproofing
The core requirements for the wiring of building lighting grid screens are "standardized and orderly, waterproof and moisture-proof, and easy to operate and maintain". If the outdoor wiring is not standardized and the waterproofing is not in place, it is easy to encounter problems such as short circuits and leakage, which will affect the service life of the grid screen and even cause safety hazards. During the wiring process, it is important to focus on the following key points:
Power lines and signal lines need to be wired separately to avoid mutual interference and affect control signals and display effects; The wiring path should avoid protruding parts and sharp corners of the building to prevent scratches and wear on the circuit; The fixation of the line needs to be firm, using wire clips and cable trays to avoid loosening and sagging of the line, especially for high-altitude wiring. It is necessary to ensure that the line is firmly fixed to prevent wind shaking and line breakage.
Waterproof treatment is the core of outdoor wiring, and all line joints and interfaces need to be well waterproofed. Waterproof joints and waterproof tape should be used to wrap them, ensuring no gaps and avoiding rainwater from entering and causing short circuits in the lines; The ends of power and signal lines should be sealed to prevent water ingress; After the wiring is completed, all lines need to be inspected to confirm that the connections are firm, waterproof, and free of exposure or damage.
In addition, during the wiring process, a certain amount of line margin should be reserved to facilitate later debugging and operation, avoiding short lines that cannot be adjusted; At the same time, the specifications of the circuit need to be adapted to the power of the grid screen to avoid overloading the circuit, which may cause heating and short circuits.
(4) Waterproof reinforcement: multiple protections, suitable for outdoor environments
Most of the lighting grid screens of the building are installed outdoors. Facing rainstorm, rain soaking and other environments, waterproof reinforcement is crucial. "Multiple protection" is required to ensure that the grid screens are used outdoors for a long time without water ingress, moisture and other problems. The specific protection points are as follows:
Waterproof of the grid screen itself: Confirm that the protection level of the grid screen reaches IP67 or above, the lamp beads adopt waterproof packaging technology, and the frame adopts sealed design to prevent rainwater from entering the interior of the equipment; Before installation, it is necessary to check the waterproof sealing of the grid screen
Waterproofing of installation site: For the connection between the grid screen and the building facade, as well as the line joints, waterproof sealant should be applied evenly without bubbles to ensure waterproofing effect; For the joint parts of curved and curved buildings, flexible sealant should be used to fit the building shape and avoid loose sealing.
Drainage treatment: Drainage holes should be installed below the grid screen to prevent rainwater from accumulating on the surface of the grid screen and soaking the equipment; If there is a water accumulation area on the exterior facade of the building, the installation position should be adjusted to avoid installing the grid screen in the water accumulation area. At the same time, drainage measures should be taken to ensure that rainwater can be discharged smoothly.
3. Post installation commissioning and acceptance: comprehensive inspection to ensure compliance
After installation, everything is not perfect. Comprehensive debugging and acceptance are needed to confirm that the display effect, operational stability, and installation safety of the grid screen meet the requirements, in order to avoid problems that may affect use in the later stage. Debugging and acceptance should focus on the following three aspects:
(1) Display effect debugging
Power on the grid screen to test its display performance, adjust brightness, contrast, and color temperature to ensure clear images, uniform colors, and no issues such as dark spots, bright spots, or color differences; Play different types of lighting content (text, logo, video, pattern), confirm that the screen is smooth, without any stuttering, ghosting, or discontinuity issues; Check the multi screen linkage effect (if any), confirm that all grid screens play synchronously without delay or misalignment. At the same time, adjust the clarity and brightness of the image according to the viewing distance to ensure that the image is complete and clear when viewed from a distance, and there is no obvious pixel graininess when viewed up close.
(2) Stability debugging during operation
Run the grid screen continuously for 24-48 hours, test the stability of the equipment, check if the light beads, control system, and wiring are normal, and there are no issues such as heating, short circuits, or fault alarms; Test the remote control function, confirm that it can remotely switch on/off, adjust the screen, update content, control sensitively, and without delay; To check the waterproof performance, manual water spraying can be used to test the waterproof effect of the grid screen, confirm that there are no water or moisture issues, and that the equipment is operating normally.
(3) Installation acceptance
During acceptance, it is necessary to compare the installation plan and comprehensively inspect the installation quality: check the fixing condition of the product, confirm that the installation is firm, flat, and free of looseness or deformation; Check the splicing situation of the grid screen, confirm that the splicing is flat, the gaps are uniform, and there is no misalignment or protrusion; Check the wiring situation, confirm that the circuit is standardized, orderly, waterproof in place, and free of exposure or damage; Check the waterproof reinforcement situation, confirm that the sealant is evenly applied without gaps, and that the drainage holes are unobstructed. At the same time, records should be kept during acceptance, and any existing problems should be promptly requested to be rectified by the construction team until they meet the standards.
Additional suggestions for the selection and installation of building lighting grid screens
1. Choose a reputable manufacturer and focus on product quality and after-sales service. Building lighting grid screens are long-term outdoor equipment, and product quality and after-sales service are crucial. It is recommended to choose a reputable grid screen manufacturer to ensure that the product meets relevant national standards and has comprehensive after-sales service (such as warranty period, on-site debugging, fault repair, etc.). Avoid choosing low-priced and low-quality products. Although these products have low procurement costs, they have poor protective performance, short service life, frequent failures in the later stage, extremely high operation and maintenance costs, and may even pose safety hazards.
2. Balancing energy efficiency and reducing later operation and maintenance costs. Outdoor building lighting, the energy consumption of grid screens is an important component of later operation and maintenance costs. It is recommended to choose low-power grid screen products, which use energy-saving light beads and intelligent control systems to automatically adjust brightness according to environmental brightness, reduce energy consumption, and extend service life. In addition, when selecting, you can choose a grid screen that supports time-division dimming, adjust brightness and running time according to lighting requirements, and further reduce energy consumption.
4. Carry out post operation and maintenance to extend the service life of equipment. After the installation of the grid screen is completed, regular operation and maintenance should be carried out, such as regularly cleaning the dust and debris on the surface of the grid screen, checking the fixing of the bracket, inspecting the aging of the circuit and sealant, timely replacing damaged light beads and accessories, and ensuring long-term stable operation of the equipment. Regular maintenance can not only extend the service life of grid screens, but also avoid major failures and reduce maintenance costs.
summary
The selection and installation of building lighting grid screens rely on "precise adaptation" - resolution adaptation to viewing distance and building scene, installation adaptation to building structure and outdoor environment, both of which are indispensable. When making a purchase, it is necessary to abandon the misconceptions of "only looking at price" and "blindly pursuing high resolution", and scientifically choose the specifications, resolution, and protection level of the grid screen based on one's own building type, viewing distance, and lighting needs; During installation, it is necessary to strictly follow the specifications, control the core details such as bracket fixation, splicing, wiring, waterproofing, etc., to ensure safe, standardized, and aesthetically pleasing installation.
Only by doing a good job in every aspect of selection and installation can we create a building night scene project that combines visual impact, safety, durability, and energy efficiency. This not only enhances the beauty and brand influence of the building, but also controls procurement costs and later operation and maintenance costs, achieving a dual improvement in economic and social benefits.
