LED Module Mounting for Cabinet Sign Retrofit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retrofitting large cabinet signs with LED modules is challenging due to the lack of standard sizes for fluorescent lamps, leading to inefficient lighting as top and bottom light emission from fluorescent tubes is wasted, and existing solutions complicate the process with additional light-blocking layers.
Innovation Solution
A mounting arrangement for LED modules that includes frames and holding bases to secure the modules to existing raceway structures, allowing for easy installation and minimizing light blockage, with adjustable frames and transparent panels to ensure even illumination on both sides of the signage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If fluorescent tubes are used to illuminate cabinet signs, then the signs can be evenly illuminated on both front and rear panels, but light emitted from top and bottom portions is wasted and does not reflect well toward the illuminated panels
Solution Approach 1:
The patent transitions from linear fluorescent tube illumination to a planar LED module configuration with transparent panels. The LED module is mounted within a frame that allows light emission from multiple directions (front, rear, top, bottom), converting the illumination pattern from one-dimensional linear emission to three-dimensional omnidirectional emission, thereby eliminating wasted light and improving overall illumination efficiency.
2Use of energy by moving object
If LED modules are designed to replace fluorescent lamps in non-standard sized cabinet signs, then energy efficiency and lifespan are improved, but the lack of standard sizes makes it difficult to design LED retrofit lamps that fit and evenly illuminate the space
Solution Approach 1:
The patent divides the illumination system into modular components: a standardized LED module, a frame structure, and transparent panels. These segmented components can be independently configured and assembled to fit various cabinet sign dimensions, providing adaptability to non-standard sizes while maintaining the energy efficiency benefits of LED technology.
Solution Approach 2:
The LED module design incorporates universal mounting features and adjustable frame configurations that enable the same basic module to be adapted to different cabinet sign sizes and geometries. The transparent panels can be cut to various dimensions, allowing a single LED module design to serve multiple application scenarios with different size requirements.
3Strength
If additional layers are added to support LED modules, then the structure can support the LED modules, but these layers block the light from the LEDs
Solution Approach 1:
The patent uses transparent panels (made of glass or transparent plastic) as the supporting structure for the LED modules. These thin, transparent films provide the necessary structural support while allowing light to pass through without significant blockage, unlike traditional opaque mounting layers. The transparency of these panels ensures that light from the LEDs can reach the illuminated surfaces effectively.
4Ease of operation
If a simple mounting structure is used for LED modules, then installation and maintenance are easier, but the structure may not provide adequate support for the modules
Solution Approach 1:
The patent incorporates adjustable and removable mounting components that allow the LED modules to be easily installed, positioned, and maintained. The frame structure includes adjustable mounting brackets and removable fasteners that provide dynamic configuration options, enabling simple installation while maintaining adequate structural support. The modular design allows for easy disassembly and reassembly without compromising the strength of the mounting structure.
