Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light reactors suffer from non-homogeneous radiation fields, low power density, and difficulty in adjusting the spectral range for different reactions, limiting their efficiency and reaction times.
Innovation Solution
A light reactor design featuring a ring-shaped arrangement of multiple light sources and optical elements around the receiving chamber, directing light beams to converge at the center, creating a constricted, rotationally symmetric radiation field with high power density and uniformity, allowing for precise control and adjustment of the spectral range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a single light source is used to irradiate the receiving chamber, then the device complexity is low, but the radiation field is non-homogeneous and power density is low
Solution Approach 1:
The patent divides the single light source into multiple light sources arranged in a ring configuration around the receiving chamber. Each light source is equipped with its own optical element, creating a segmented illumination system that delivers homogeneous high-power-density radiation while maintaining manageable device complexity through modular architecture
Solution Approach 2:
The patent combines multiple light sources and their associated optical elements into a unified ring-shaped arrangement around the receiving chamber. This merging of components creates a coordinated system where all light sources collectively produce a homogeneous radiation field with high power density at the center, resolving the contradiction between simplicity and performance
2Illumination intensity
If LED strips with cluster-like distributed LEDs are used, then large-area treatment achieves more uniform radiation intensity, but precision irradiation onto a defined reaction space is limited
Solution Approach 1:
The patent assigns different optical elements to different light sources in the ring arrangement, with each optical element tailored to direct light precisely onto specific regions of the receiving chamber. This local optimization allows homogeneous illumination across the entire reaction space while maintaining precise irradiation control, overcoming the limitations of uniform LED strip distributions
Solution Approach 2:
The patent transitions from the planar LED strip arrangement to a three-dimensional ring configuration surrounding the receiving chamber. This spatial reorganization enables precise angular control of light beams from multiple directions, achieving both radiation uniformity and irradiation precision that cannot be obtained with two-dimensional LED distributions
