Luminous Apparatus Insect Attraction Prevention via Luminance Gradient
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luminous apparatuses, such as automatic vending machine displays, attract insects due to light emission, and existing solutions either require additional devices like sound wave generators or alter the light's hue by cutting specific wavelengths, leading to discomfort and color changes.
Innovation Solution
A luminous apparatus with a peripheral edge region formed as a low-attraction region through an optical property gradient, where luminance gradually decreases from the inward to the outward side, reducing insect attraction by utilizing a luminance attenuation region, which can be achieved by laminating a light transmissive sheet with decreasing light transmissibility or arranging light sources with decreasing density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If light of specific wavelength is cut to reduce insect attraction, then insect attraction is reduced, but light color changes (yellow tinge)
Solution Approach 1:
The invention applies different optical properties to different regions of the light emission surface. The peripheral edge region has a low-attraction region with gradient optical properties that reduce insect attraction, while the central region maintains normal light emission properties for effective illumination and advertising display.
Solution Approach 2:
The light emission surface is divided into distinct functional regions: a central high-luminance region for effective illumination and advertising display, and a peripheral low-attraction region with gradient optical properties that reduce insect attraction. This segmentation allows each region to optimize its specific function without compromising the other.
2Object-affected harmful factors
If additional sound wave generator is incorporated to prevent insect attraction, then insect attraction is reduced, but device complexity increases
Solution Approach 1:
The invention merges the insect repellent function directly into the existing light emission structure by creating a low-attraction region within the light emission surface itself. This eliminates the need for separate sound wave generators or additional devices, as the optical structure itself provides both illumination and insect protection functions.
Solution Approach 2:
The light emission surface structure itself provides the insect protection function through its own optical properties. The gradient optical property region in the peripheral edge automatically reduces insect attraction without requiring external control systems, sensors, or additional energy-consuming devices.
3Object-affected harmful factors
If light source density is decreased at peripheral edges to reduce insect attraction, then insect attraction is reduced, but overall illumination intensity decreases
Solution Approach 1:
The invention applies different light source densities to different regions: the central region maintains high light source density for effective illumination, while the peripheral edge region uses a low-attraction region with gradient optical properties that reduce insect attraction without significantly impacting overall illumination.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively prevents insect attraction while maintaining the original light color, with a luminance attenuation region of 100 mm or more significantly reducing insect attraction and 200 mm or more ensuring minimal attraction, making it suitable for existing apparatuses by applying a light transmissive sheet or adjusting light source density.
Implementation Method 1
a peripheral edge region of a light emission surface of a luminous apparatus is formed as a low-attraction region which is less capable of attracting bugs, the low-attraction region being composed of an optical property gradient region whose at least one optical property gradually changes in a direction from an inward side to an outward side of the light emission surface
