Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional UV light source lamps used in insect traps have high power consumption, short lifespan, and environmental pollution issues, and replacing them with UV LEDs can decrease insect trapping efficiency due to differences in light emission characteristics.
Innovation Solution
An insect trap design utilizing a UV LED lamp with a printed circuit board, emitting UV light with a peak wavelength of 335-395 nm, a diffusion angle of 120° or less, and a spectrum half-width of 14.5 nm or less, integrated with a suction fan and a transparent housing for enhanced UV light concentration and directionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional UV light source lamps are used in insect traps, then insect trapping effect is maintained, but power consumption is high and lifespan is short
Solution Approach 1:
The patent changes the fundamental parameters of the UV light source by transitioning from conventional lamps (mercury, excimer, deuterium) to UV LEDs. This parameter change includes switching from gas discharge or arc-based UV generation to electroluminescence in semiconductor materials, fundamentally altering how UV light is produced to reduce power consumption and extend lifespan while maintaining trapping effectiveness
Solution Approach 2:
The patent replaces the mechanical/electrical systems of conventional UV lamps (which require ballasts, starters, and generate significant heat) with a solid-state LED system that uses electroluminescence to generate UV light directly, eliminating the need for complex supporting mechanical systems and reducing overall power consumption
2Use of energy by moving object
If UV LED is simply replaced in conventional insect trap, then power consumption is reduced, but insect trapping effect decreases
Solution Approach 1:
The patent optimizes the UV LED parameters by selecting specific wavelengths (335-395 nm peak) that match insect attraction spectra, adjusting the diffusion angle (120° or less) to concentrate UV light effectively, and controlling spectrum half-width (14.5 nm or less) to enhance wavelength specificity, thereby maintaining high trapping efficiency while using LED technology
Solution Approach 2:
The patent applies local quality optimization by directing UV light with a controlled diffusion angle of 120° or less toward the trapping portion, concentrating the UV radiation in specific directions where it is most effective for attracting and trapping insects, rather than distributing it uniformly in all directions
3Reliability
If conventional UV lamps are used, then insect attraction is effective, but heat generation is high and environmental pollution occurs
Solution Approach 1:
The patent replaces conventional lamp-based UV generation (which produces significant heat and requires toxic gases like mercury) with solid-state UV LED technology that generates UV light through electroluminescence, eliminating the need for toxic fill gases and dramatically reducing heat generation while maintaining insect attraction effectiveness
Solution Approach 2:
The patent converts the potential harm of UV radiation by using LEDs to produce UV light more efficiently with less waste heat, and eliminates the harm of toxic gases by using solid-state semiconductor materials, thereby benefiting from UV's insect-attracting properties without the associated environmental and thermal harms
