Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lighting systems face challenges with fluorescent tubes due to limited lifetime, inefficient light distribution, and mercury content, while LED solutions often compromise between efficiency and glare, with diffusers being inefficient and causing eye discomfort.
Innovation Solution
A lighting apparatus with LEDs oriented opposite the work surface, using a support structure and heat dissipating element, and incorporating optical elements to redirect light away from the primary illumination direction, optimizing light distribution and reducing glare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If LEDs are oriented in direct line of sight to the work surface, then optical efficiency is improved, but glare increases causing eye discomfort
Solution Approach 1:
The patent inverts the conventional LED orientation by positioning LEDs facing upward (toward the ceiling) rather than downward (toward the work surface). This inversion allows light to bounce off the ceiling and reach the work surface indirectly, maintaining optical efficiency while eliminating direct glare to the user's eyes.
Solution Approach 2:
The patent introduces the ceiling as an intermediary surface that redirects light from the LEDs to the work surface. By using the ceiling as a mediator, the system achieves efficient light distribution without direct line-of-sight exposure to the LED source, thereby reducing glare while maintaining illumination effectiveness.
2Object-affected harmful factors
If a diffuser is used to control glare, then glare is reduced, but optical efficiency decreases
Solution Approach 1:
The patent extracts and removes the diffuser component from the lighting system. Instead of using a diffuser to scatter and reduce glare, the design relies on the geometric orientation of LEDs facing upward and the natural reflection properties of the ceiling, thereby eliminating the optical losses associated with diffusers while still controlling glare.
3Use of energy by moving object
If fluorescent tubes are replaced with LED solutions, then energy efficiency is improved, but device compatibility with existing fixtures becomes challenging
Solution Approach 1:
The patent designs the LED lighting module with universal adaptability to fit existing fluorescent tube fixtures. By creating a multi-functional device that can be installed in standard T8 and other common fixture types, the invention enables widespread adoption of energy-efficient LED technology without requiring infrastructure changes, thereby maintaining fixture compatibility while achieving energy savings.
