With the continuous acceleration of urbanization, super high-rise buildings have become an important component of the urban skyline. Whether it is a business office building, a five-star hotel, a commercial landmark, or an urban complex, high-rise buildings over 100 meters have a much higher visual height, recognition, and dissemination power at night than low rise buildings. Their facade lighting design not only concerns the appearance and temperament of the building, but also carries the expression of urban spirit and the transmission of commercial value.
The design challenge of lighting for high-rise buildings over 100 meters high
1. Power supply difficulties caused by height
Traditional 24V or 12V LED lighting fixtures face serious voltage attenuation and power supply distance limitations when applied in high-rise buildings. Generally, the power supply distance of each cable is only between 5-15 meters, resulting in complex wiring, numerous connectors, and difficult maintenance.
2. Signal synchronization and stability issues
When implementing dynamic lighting effects (such as running horses, text, videos, etc.) on ultra-high facades, the signal must be synchronized and consistent. If the signal transmission distance is too long, it is prone to problems such as time difference, code interruption, and control failure.
3. High installation and construction difficulty
High altitude operations not only pose safety risks, but also require higher requirements for the installation of lighting fixtures, power/signal wiring, and structural compatibility. Traditional point light sources, wall washers, and floodlights are often difficult to accurately control light efficiency in high-rise buildings, and installation is cumbersome.
4. High maintenance costs in the later stage
Once local lighting fixtures are damaged, if modular disassembly, unified power supply, remote control and other functions are not considered in the early design, later maintenance will be extremely difficult, and even affect the display effect of the entire facade.
Core logic of the solution: DC48V video light strip+integrated power supply control design
To solve the lighting difficulties of high-rise buildings mentioned above, we recommend using DC48V video light strip products, combined with our independently developed integrated power supply and intelligent control system, to achieve the lighting goals of "high efficiency, safety, stability, and low maintenance".

Analysis of the entire process of lighting project: from conception to implementation
1. Preliminary planning: Lighting positioning and vision sorting
Clearly define the functional attributes of the building (commercial/office/hotel)
Determine the core goals of lighting: visual communication, creating urban landmarks, brand expression, festival linkage, etc
Communicate with Party A or the design institute regarding urban planning restrictions, power access locations, safety approval processes, etc
2. Facade analysis and lighting strategy design
Partition lighting based on building height, facade material, and structural features:
| Building location | Suggested lighting fixtures | Application purpose |
| Facade contour | DC48V video light strip | outlines the building form, enhancing recognition |
| Curtain wall facade | DC48V video light strip+wall wash light | play dynamic images and enhance visual dynamism |
| High brightness floodlights and linear lights | top eaves | enhance the skyline and increase long-range visibility |
| Entrance gate | Small ptich point lights | Guide the gaze and enhance the brand impression |
| The central structural node | linear lights outdoor | enrich the facade hierarchy and enhance the aesthetic appeal |
| Side wall/corner | neon light strips | fill gaps and enhance continuity |
3. Lighting effect design and simulation
●Visualize and render the overall night scene effect using 3D simulation software;
●Design lighting content: customizable logo animations, holiday patterns, welcome messages, etc;
●Rendering the overall effect under different color temperatures, brightness, and dynamic rhythms;
●Provide multiple version scheme comparisons (static+dynamic scenarios) for Party A;
4. Control system and wiring design
●Use centralized power supply and partition control logic;
●Recommend using a combination of fiber optic and network cable signal wiring to improve control accuracy and anti-interference ability;
●The lighting fixtures are uniformly connected to the intelligent controller, supporting scheduled playback, cloud synchronization, and remote debugging;

●Suggested construction sequence: main control deployment → bracket installation → light strip laying → signal debugging → overall testing;
●Use a handheld controller and remote platform for synchronous testing to avoid pixel misalignment or color errors;
7. Post maintenance and remote operation and maintenance strategies
●The light strip adopts a pluggable structure, which can be quickly replaced after damage;
●The control system supports cloud based remote management, allowing for real-time monitoring of operational status;
●Provide annual inspection services, emergency response mechanisms, and lighting content update services;
●Suggest that customers establish a "lighting operation team" or sign a remote content operation and maintenance service package with our company;
major advantages of DC48V video light strip products in high-rise lighting
1.Ultra long power supply: single-sided 70 meter power supply distance
Traditional 24V products only support 5-10 meters, while 48V led linear light bars minimize the number of power supply points and power boxes, significantly reducing wiring costs.
2.Integrated design: power supply+signal integration
Using our self-developed signal fusion cable, only one five core wire is needed between the lighting fixture and the controller, achieving plug and play functionality and greatly simplifying construction.
3.Controllable point by point, displaying powerful display
Can play videos, animations, and scrolling subtitles, supports 24 frame video input and pixel by pixel synchronization, creates stunning visual effects at night, and has strong dissemination power.
4.High protection structure, adaptable to extreme weather conditions
IP65 protection level, UV resistance, high temperature resistance, lightning protection, suitable for high temperature, high humidity, and high salt environments in the Middle East, North Africa, Southeast Asia, and other regions.
5.Lightweight design, convenient for high-altitude construction
The weight of each meter of light strip is ≤ 0.8kg, and installation does not require heavy supports, reducing the pressure of high-rise loads and improving construction safety.
