Germicidal Panel Light Air Guiding Plane Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
UV germicidal panel lights generate high noise due to strong air convection during air sterilization, which is undesirable for both noise reduction and improved fan efficiency.
Innovation Solution
The design incorporates air guiding planes at the air inlet and outlet, a centrifugal fan, and a containing groove for the lighting component, which slows down air flow and reduces noise while maintaining high air volume, and the lighting component is positioned to recycle light and reduce overall thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the working power of the fan is improved to speed up air flow and improve air sterilization efficiency, then air sterilization efficiency is improved, but high noises are generated
Solution Approach 1:
The air flow path is segmented into multiple sections with guiding planes at different locations (air inlet, air outlet, and internal passages). These guiding planes divide and direct the air flow in a controlled manner, reducing turbulence and noise while maintaining efficient air circulation for sterilization.
Solution Approach 2:
Guiding planes are introduced as intermediary structures between the fan and the air inlet/outlet. These guiding planes mediate the air flow transition, smoothing the flow paths and reducing the direct impact of high-velocity air flow on noise generation while preserving the fan's high working power for efficient sterilization.
2Productivity
If air convection is strengthened to improve sterilization, then air sterilization efficiency is improved, but noises are generated
Solution Approach 1:
Guiding planes are strategically positioned at specific locations (air inlet, air outlet, and internal passages) where air flow turbulence occurs. These local modifications create controlled flow patterns that reduce noise generation at critical points while maintaining overall air convection efficiency for sterilization.

Function Achieved in This Case
The solution effectively reduces noise generation while maintaining high air sterilization efficiency and improving lighting quality and cost-effectiveness.
Implementation Method 1
an air guiding plane corresponding to the air inlet is formed on the inner wall of the mounting cavity, when air flows into the mounting cavity from the air inlet, air is guided by the air guiding plane, so that air can flow into the mounting cavity slowly
Implementation Method 2
a fan component is provided in said mounting cavity... said fan component is a centrifugal fan
Implementation Method 3
negative pressure is generated inside the mounting cavity when the fan component works, so that air enters the mounting cavity from the air inlet
Implementation Method 4
the appearance of the housing is provided with a containing groove where the lighting component is provided, so that the inner wall of the containing groove reflects the ray of light of the lighting component to recycle ray of light
Implementation Method 5
The UV germicidal panel light can be used for air sterilization. Its sterilization principle is that air is sucked into the light for UV irradiation
Implementation Method 6
said sterilization component is a UV fluorescent tube
