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 concerns, and replacing them with UV LEDs can decrease insect trapping efficiency due to differences in light emission characteristics.
Innovation Solution
An insect trap design incorporating a UV LED lamp with a printed circuit board, multiple UV LED chips emitting light within a specific wavelength range (335-395 nm) and a diffusion angle of 120° or less, optimized for increased radiant flux and spectral concentration, along with a transparent housing for improved UV light transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional UV light source lamps (mercury lamps, excimer lamps, deuterium lamps) are used, then sufficient UV light output is achieved, but power consumption is high, heat generation is high, life span is short, and toxic gas causes environmental pollution
Solution Approach 1:
The patent replaces conventional UV light source lamps (mercury lamps, excimer lamps, deuterium lamps) with UV LED packages. This substitution eliminates the need for toxic gases and reduces power consumption while extending operational life span. The UV LED packages convert electrical energy directly to UV light through electroluminescence, avoiding the mechanical and chemical limitations of traditional lamp technologies.
Solution Approach 2:
The patent changes the fundamental light generation mechanism from thermal/arc-based (conventional lamps) to electroluminescence (LED). This parameter change enables lower operating temperature, reduced power consumption, and extended lifespan. The UV LED packages operate at lower temperatures and consume less energy while maintaining sufficient UV output for insect attraction.
2Object-generated harmful factors
If UV LED packages are used to replace conventional UV lamps, then power consumption is reduced and environmental pollution is eliminated, but production cost is considerably higher and insect trapping efficiency decreases due to different light emission characteristics
Solution Approach 1:
The patent applies local quality by positioning multiple UV LED packages at specific locations within the housing to create concentrated UV light zones. The LED packages are arranged to emit UV light toward the duct opening where insects are most likely to approach. This localized UV emission strategy maintains high trapping efficiency while using fewer LEDs than a uniform distribution would require.
Solution Approach 2:
The patent combines multiple UV LED packages into a single integrated lighting system. The packages are mounted on internal surfaces of the housing and work together to create a comprehensive UV illumination field. This merging approach distributes the total UV output across multiple sources, achieving the required trapping efficiency while leveraging the energy-efficient characteristics of LED technology.
3Ease of manufacture
If UV LED lamp is simply replaced in conventional insect trap, then component update is achieved, but insect trapping effect decreases because light-emission characteristics of UV LED differ from conventional UV light source lamp
Solution Approach 1:
The patent implements dynamic design by making the UV LED packages and their mounting positions adjustable. The LED packages can be positioned at optimal locations within the duct housing to maximize UV light exposure in the insect trapping zone. This dynamic positioning capability allows the system to adapt to different operational conditions and maintain high trapping efficiency despite the different emission characteristics of LED versus conventional lamps.
Solution Approach 2:
The patent utilizes the internal surfaces of the duct housing as mounting dimensions for the UV LED packages. By attaching LEDs to the inner walls and ceiling of the housing rather than simply replacing a single central lamp, the system creates UV light emission from multiple spatial dimensions. This multi-dimensional approach compensates for the directional emission limitations of individual LED packages.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The UV LED lamp configuration enhances insect trapping efficiency by concentrating UV light intensity, resulting in a trapping efficiency at least five times higher than conventional UV light source lamps, while reducing environmental impact and energy consumption.
Implementation Method 1
A plurality of UV LED chips may be mounted on the PCB, and may emit UV light having a peak value of substantially the same wavelength. UV light that is emitted from the UV LED chip may have a peak wavelength of 335-395 nm.
