UV-A LED Lighting Body with Fluorescent Conveyor for Insect Attraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insect traps are ineffective in attracting a wide range of harmful and pest insects from great distances and often fail to capture specific species, such as moths, due to their reliance on single-wavelength UV-A light sources, which can be overwhelmed by broader light sources and are not adaptable to different environments or insect populations.
Innovation Solution
A lighting body that combines a conical UV-A LED light source with a movable conveyor body capable of converting UV-A rays into a broader spectrum of visible light, along with a reflecting body to increase the light's intensity and range, allowing for a dual attraction mechanism using UV-A rays and colored visible light to attract various insect species.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If UV-A LED light source is used to attract insects, then energy consumption is reduced and environmental harm is minimized, but the attraction range and effectiveness against diverse insect species are limited
Solution Approach 1:
The patent combines UV-A LED light source with a conveyor body that converts UV-A rays into visible light, creating a hybrid lighting system that merges the energy efficiency of UV-A LEDs with the broad-spectrum attraction capability of visible light, thereby resolving the contradiction between environmental harm reduction and attraction versatility
Solution Approach 2:
The conveyor body dynamically changes the wavelength parameters of the emitted light by converting UV-A rays (315-400 nm) into visible light across different wavelengths, allowing the system to adapt to different insect species' spectral sensitivity and expand attraction effectiveness while maintaining energy efficiency
2Device complexity
If single-wavelength UV-A light is used, then device complexity is reduced, but the ability to attract different types of insects from great distances is insufficient
Solution Approach 1:
The conveyor body acts as an intermediary component that receives UV-A rays from the LED and converts them into visible light, extending the attraction range without requiring multiple LED sources or complex multi-wavelength lighting systems, thus maintaining device simplicity while increasing effectiveness
Solution Approach 2:
The movable conveyor body introduces dynamic capability to the system, allowing it to adjust its position and optimize the conversion of UV-A to visible light in real-time, thereby extending attraction range and adaptability without increasing static device complexity
3Length of moving object
If conventional light sources are used to attract insects, then attraction range is improved, but energy consumption increases and environmental pollution is generated
Solution Approach 1:
The patent replaces conventional high-power light sources with UV-A LEDs that consume less energy, and uses a conveyor body with optical conversion capability to achieve the necessary attraction range, substituting mechanical/electrical power consumption with optical energy transformation
