Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fluorescent lights pose disposal problems due to toxic materials, and existing LED replacements do not fully address the need for efficient light distribution and thermal management in standard fluorescent fixtures.
Innovation Solution
The development of LED-based lights with elongate housings featuring canted outer walls and end caps, which include an LED circuit board and power supply circuit board, provide efficient light distribution and thermal management by redistributing light and dissipating heat, while being compatible with standard fluorescent fixtures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional fluorescent lights are used, then they provide adequate illumination, but they pose disposal problems due to toxic materials
Solution Approach 1:
The patent extracts and removes the toxic materials (mercury, phosphor powders) from the lighting system by replacing the fluorescent tube with an LED-based light that uses无毒 solid-state LEDs and safe housing materials, eliminating disposal problems while maintaining manufacturing feasibility
Solution Approach 2:
The patent changes the fundamental parameters of the light source from fluorescent (gas-discharge, toxic materials) to LED (solid-state,无毒 materials), transforming the material composition and operational characteristics to eliminate harmful factors
2Object-affected harmful factors
If LED-based lights are designed as one-for-one replacements for fluorescent lights, then they eliminate toxic materials, but they do not fully address efficient light distribution and thermal management
Solution Approach 1:
The patent applies asymmetric canted outer walls to the housing that redirect light distribution patterns to match standard fluorescent fixture requirements, creating non-uniform light redirection surfaces that optimize illumination while eliminating toxic materials
Solution Approach 2:
The patent introduces intermediary elements including reflective surfaces, diffusing materials, and thermal management components between the LED source and the environment to optimize light distribution and heat dissipation, ensuring reliable performance in standard fixtures
3Illumination intensity
If LED-based lights are designed with canted outer walls, then light distribution is improved, but the housing design becomes more complex
Solution Approach 1:
The patent segments the housing into modular components including the canted outer wall section, base, and end caps, allowing the complex light-distributing geometry to be manufactured as separate pieces that assemble together, reducing overall manufacturing complexity while maintaining optical performance

AI summary
An LED-based light has an elongate housing having a longitudinal axis and a vertical axis, the housing defined by a base and two canted outer walls meeting opposite the base, the housing defining a cavity. An LED circuit board on which a plurality of LEDs are located is positioned within the cavity. End caps are positioned at opposite ends of the housing.
