LED Billboard System with Modular Backlighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an LED billboard system that can be easily and conveniently attached to pre-existing billboard structures, as well as other structures like walls, roofs, cars, and trucks, to provide illumination in low visibility conditions such as dusk, nighttime, or adverse weather.
Innovation Solution
The LED billboard system consists of modular LED panel units with a unique mounting system using blow-molded panels, aluminum brackets, and a graphic wrap, allowing for easy attachment to existing structures, with LED light boards that can be controlled for uniform or customized lighting, and can be retrofitted onto various billboard sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional lighting structures are installed on the front of the billboard to illuminate the sign, then visibility during nighttime is improved, but the device complexity and weight increase
Solution Approach 1:
The billboard is divided into modular panels, each with integrated LED lighting elements. This segmentation allows the lighting function to be distributed across multiple independent units, reducing the complexity of any single lighting structure while maintaining overall illumination effectiveness.
Solution Approach 2:
The lighting structure is merged with the billboard panel itself, combining the illumination function with the display structure. This integration eliminates separate lighting assemblies and reduces overall device complexity while providing effective nighttime visibility.
2Illumination intensity
If conventional billboard structures are used with additional lighting structures, then nighttime illumination is achieved, but the weight of the structure increases
Solution Approach 1:
The lighting elements are merged into the billboard panel construction, eliminating the need for separate lighting structures. This integration significantly reduces the additional weight that would be required for conventional external lighting assemblies while maintaining nighttime illumination capability.
Solution Approach 2:
LED elements are used instead of traditional lighting components, providing a lighter, more energy-efficient solution with longer operational life, thereby reducing both initial weight and long-term maintenance burden.
3Illumination intensity
If LED lighting systems are integrated into billboard panels, then visibility in low light conditions is improved, but manufacturing complexity increases
Solution Approach 1:
The billboard is constructed from standardized modular panels with pre-integrated LED elements. This segmentation allows for simplified manufacturing of individual units that can be produced using conventional techniques, reducing overall manufacturing complexity while achieving effective LED illumination.
Solution Approach 2:
The modular panel design creates universal building blocks that can be used across different billboard configurations. This universality simplifies manufacturing processes and inventory management while providing consistent LED illumination performance across all panels.
4Ease of operation
If modular LED panel units with mounting systems are used, then ease of installation on pre-existing structures is improved, but the number of components increases
Solution Approach 1:
The billboard system is segmented into modular panels with integrated mounting features, allowing for simplified installation on pre-existing structures. While this creates multiple components, the standardization and integration of mounting systems into each panel reduces the overall installation complexity and time required.
Solution Approach 2:
Mounting features and attachment mechanisms are pre-integrated into the panel design during manufacturing. This preliminary action eliminates the need for separate mounting hardware installation steps, simplifying the overall installation process despite the presence of multiple components.
