Backlit Banner Display System with Internal LED Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backlit banner displays face challenges with uneven illumination, particularly on glossy graphics and dual-sided displays, due to the additional weight and positioning of light strips, which complicate installation and obscure certain areas.
Innovation Solution
A modular display system with a rectangular frame that encloses two banners on opposite sides, featuring internal LED light strips for uniform backlighting, allowing for even illumination of both sides and adjustable configurations without additional tools or components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light strips are incorporated along the pull bar and housing to illuminate the banner, then visibility of the banner is improved, but the additional weight makes installation more difficult and requires additional support from the support leg
Solution Approach 1:
The patent transitions from external lighting (front/side illumination) to internal backlighting by placing light sources behind the banner within the housing. This dimensional change allows light to pass through the banner material, providing uniform illumination without adding weight to the visible external structure or requiring additional support legs.
Solution Approach 2:
The lighting system is merged with the existing housing structure. The light sources are integrated into the housing space that already exists to support the banner, eliminating the need for separate external lighting fixtures and their associated mounting hardware and support structures.
2Illumination intensity
If light strips are positioned along the top and bottom of the banner, then illumination is provided, but certain portions of the banner are obscured and view is blocked especially on glossy graphics
Solution Approach 1:
The lighting approach moves from edge-based illumination (top and bottom) to area-based backlighting. By placing light sources in the housing behind the entire banner surface, light passes through the full area of the banner, eliminating shadow zones and view obstructions that occur with edge lighting, especially on glossy surfaces that reflect light.
3Illumination intensity
If light strips are used to illuminate the banner, then visibility is improved, but the position of light strips may not fully illuminate an entire area of the banner
Solution Approach 1:
The patent applies lighting locally across the entire banner surface by distributing multiple light sources throughout the housing space behind the banner. This ensures each region of the banner receives direct illumination from nearby light sources, achieving uniform illumination across the full area rather than relying on light traveling from distant edge positions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides uniform and even illumination across the entire banner surface, improving visibility and ease of installation by eliminating the need for external support and ensuring comprehensive lighting of both sides of the display.
Implementation Method 1
At least one light emitting device is connected to the frame and disposed within the space defined in the frame
Implementation Method 2
The two banners are backlit by the at least one light emitting device when each is in its respective extended position
