Guidelines for the production of mobile LED billboard trailers
Mobile LED billboard trailers can be used as temporary display screens for various stage performances and can also be used for street advertising. You may be curious about how mobile LED billboard trailers are built. Let’s learn about it through this article.
Prepare the components for building a mobile LED billboard trailer
Before starting to build a mobile LED billboard trailer, we need to prepare all the relevant components first.
Trailer components
GPS tracker
A mobile LED billboard trailer is not stationary in one location for extended periods, but moves continuously to display content as needed. Therefore, we must install a GPS tracker on the mobile LED billboard trailer.
The GPS tracker allows us to monitor the trailer’s location in real-time, reducing the risk of theft, and enables us to adjust vehicle scheduling based on the location data obtained.
Trailer Cover
Outdoor weather conditions can change rapidly, and a trailer cover provides the mobile LED billboard trailer with comprehensive protection against extreme weather conditions.
The trailer cover offers reliable waterproofing, dust proofing, and UV protection for the LED billboard. While outdoor LED billboards have some built-in protective features, the trailer cover provides more stable and reliable protection, also safeguarding the mobile LED billboard trailer from physical collisions, damage, or scratches.
Protective Mechanical Platform
The mechanical platform is typically made from aviation-grade cases, designed to protect the bottom mechanical structure and mobility functions of the mobile LED billboard trailer.
This aviation-grade case-made trailer platform is lightweight and compact, offering a more cost-effective alternative to larger, bulkier traditional trailer platforms. JYLED provides matching packaging and transportation services, eliminating the need for you to search for a suitable trailer platform.
LED Billboard Components
LED Cabinet
The LED cabinet is the primary display component of the mobile LED billboard trailer, integrating LED pixels, LED masks, receiving cards, and a metal housing into a single unit. The LED cabinets for mobile LED billboard trailers prioritize convenience, featuring a modular design that is lightweight, compact, and capable of rapid assembly and disassembly.
As an outdoor LED display screen, the LED cabinet of the mobile LED billboard trailer has an IP65 or higher protection rating, offering excellent waterproof and dustproof performance.
Power Cables and Signal Cables
To assemble an LED cabinet into a complete LED advertising screen, power cables and signal cables are required to connect the cabinets together. The flow of signals and power ensures that all assembled LED cabinets display as a unified whole.
Supporting Steel Structure
Adjustable steel columns serve as support columns for the LED billboard, allowing the height of the billboard to be adjusted according to on-site requirements, thereby enhancing visibility.
A steel structure support is also installed on top of the steel columns to serve as the foundation for subsequent installation of LED cabinets.
Vehicle-mounted generator
As a mobile LED billboard trailer, its primary power source is a vehicle-mounted generator that can move with the vehicle. The generator typically provides 10 kW to 24 kW of power to the LED screen.
In addition to the primary power source, a solar panel can be configured as a backup power source, which can be activated in emergencies when the generator is unable to operate.
Inverter
LED screens require alternating current (AC) power, while generators typically produce direct current (DC) power. An inverter is used to convert the generator’s DC power into the AC power required by the LED screen.
Audio System Components
Audio System
Displaying video content alone can be monotonous. To enhance promotional effectiveness, we typically equip mobile LED billboard trailers with a sound system. With the assistance of a sound system, the application scope of mobile LED billboard trailers expands beyond advertising displays to include temporary event performances and outdoor movie screenings.
Lighting
Adding auxiliary lighting to the mobile LED billboard trailer can enhance the visual experience of video playback and create a more immersive atmosphere.
Especially when using the mobile LED billboard trailer for temporary events such as stage performances, the auxiliary effect of lighting is particularly important.
Installation Methods for Mobile Advertising Trailer
Site Preparation
For safety and reliability, the site where the mobile LED billboard trailer is installed must be flat and stable.
If the soil is loose, the platform may tilt during screen installation, causing personnel to slip and fall, and posing a potential risk of physical impact damage to the LED cabinets.
Platform steel structure installation
After confirming a suitable site, the mobile trailer platform must first be assembled, followed by the installation of the mechanical structure for fixing the LED screen within the platform, including the installation of support columns and the fixed steel structure for the LED cabinets.
LED cabinet installation
After the foundation support structure is constructed, the LED cabinets can be installed. When removing the LED cabinets, ensure they are placed upright on a flat surface or face upward. Do not place them with the LED diodes facing downward, as this may cause damage to the diodes.
The top and sides of the LED cabinets typically have locking mechanisms. Use these mechanisms to secure the cabinets to the steel structure from the bottom upward.
Power supply and connections
Connect all LED cabinets in series using power cables and signal cables according to the correct connection sequence. Ensure that the connection sequence strictly follows the drawings, and that all interfaces are secure with no loose connections. Then connect the LED signboard to the inverter and generator.
Safety inspection
After the LED signboard is installed, first inspect for any exposed wires or loose connections. After inspection, attempt to power on the system and observe whether the LED screen operates normally.
If the LED advertising sign does not display normally, troubleshooting is required; if it displays normally, on-site calibration can be performed to improve the contrast and brightness of the LED advertising sign’s display for better visual effects.
Our Recommendations
Single-unit limitations
Mobile LED billboard trailers can be used for advertising campaigns or event rentals. Different businesses require different sizes of mobile LED billboard trailers. If only a single mobile LED billboard trailer is available, it may be difficult to meet customer needs, resulting in significant operational limitations.
Seasonal and climatic influences
Extreme weather conditions, such as heavy rain, snow, or wind, can reduce foot traffic on the streets, thereby lowering the marketing efficiency of mobile LED billboard trailers. It is recommended to check the weather forecast in advance and plan the trailer’s itinerary accordingly.
Urban regulation
Some urban areas have strict regulations on street-based mobile advertising signs. It is advisable to research local regulations in advance. If the area has strict regulations, obtain the necessary permits beforehand to ensure compliance with local laws.
Establishing a Trailer Fleet Control System
If you wish to launch advertising and rental services for mobile LED billboard trailers in urban areas and establish a trailer fleet for this purpose, you may require a robust trailer control system. Such a system can help you manage the trailer fleet in an orderly manner, improve fleet scheduling efficiency, and remotely control the content displayed on the mobile LED billboard trailers.
Conclusion
Mobile LED billboard trailers offer stunning visual presentations in outdoor settings. If you wish to use mobile LED billboard trailers for profit, it currently appears to be an investment with returns exceeding costs.
