Angled LED Illuminated Display Board for Message Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional illuminated display boards are inefficient in providing maximum illumination for printed or handwritten messages due to high energy consumption, short lifespan of gas discharge lamps, and insufficient illumination, and are not designed for easy message changes.
Innovation Solution
An illuminated display board with a frame, a light-transmissive panel, and a light source positioned at an angle of 25 to 50 degrees relative to the panel, utilizing a light-guiding channel and retractable hangers for enhanced illumination and easy mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If gas discharge lamps are used for edge lighting, then uniformly distributed and brightly colored light is provided, but energy consumption is high and lifespan is short
Solution Approach 1:
The patent changes the type of light source from gas discharge lamps to LEDs, representing a fundamental parameter change in the lighting technology. LEDs consume significantly less energy while providing comparable or superior illumination, directly resolving the contradiction between high brightness and high energy consumption.
2Illumination intensity
If gas discharge lamps are used for edge lighting, then uniformly distributed and brightly colored light is provided, but lifespan is short
Solution Approach 1:
The patent replaces gas discharge lamps with LEDs, changing the fundamental parameter of light source technology. LEDs have significantly longer operational lifespans (typically 50,000-100,000 hours) compared to gas discharge lamps, while maintaining or improving illumination quality, thus resolving the contradiction between brightness and lifespan.
3Illumination intensity
If light source is positioned at standard angles, then simple manufacturing is achieved, but maximum illumination of messages is not provided
Solution Approach 1:
The patent applies local quality by positioning the LED light source at a specific angle (45 degrees) relative to the board surface, optimized for maximum message illumination. This localized angular positioning enhances the illumination of written messages while the overall manufacturing process remains simple through the use of standard LED components and straightforward mounting procedures.
