Dual-Sided LED Illumination Arrays for Microbiological Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing microbiological analysis devices for detecting microorganisms using fluorophore markers lack efficient and uniform illumination, making it difficult to detect microorganisms on larger supports with high contrast and comfort.
Innovation Solution
A device with two arrays of light sources, each with light emitting diodes, are inclined towards the support to provide symmetrical and homogeneous illumination, minimizing extraneous light diffusion and reflection, and optimized for a 40°-50° angle and 39.75-69.75 mm height range for improved image rendering and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional single-sided illumination is used, then device structure is simple, but illumination uniformity is poor
Solution Approach 1:
The patent transitions from single-sided illumination to dual-sided illumination by adding light sources from another dimension (the opposite side of the support). This resolves the contradiction by achieving superior illumination uniformity through symmetrical lighting from both sides, while the modular base design keeps the structural complexity manageable.
2Area of stationary object
If support size is increased, then detection area is improved, but illumination uniformity deteriorates
Solution Approach 1:
The illumination system is segmented into multiple independent light sources arranged in arrays on both bases. This segmentation allows each light source to contribute to uniform illumination across the entire support surface, enabling the system to handle larger support areas while maintaining illumination uniformity through distributed lighting.
3Illumination intensity
If light sources are added to improve illumination, then energy consumption increases
Solution Approach 1:
The patent employs LED technology which fundamentally changes the energy efficiency parameter of the light sources. LEDs provide high-quality illumination with significantly reduced energy consumption compared to traditional lighting, allowing dual-sided illumination arrays to be implemented without excessive energy costs.
