LED Lighting Antenna Placement for Signal Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing LED lighting apparatus lacks a function to control light intensity and suffers from degraded performance of communication modules due to wave shielding by the heat radiation frame, which hinders effective signal reception for wireless control.
Innovation Solution
An antenna structure is exposed outside the heat radiation frame to improve signal reception performance, with the antenna being positioned on the top surface of the heat radiation frame and connected to a communication module, while the power supply module is placed in the reception groove to maintain electrical connectivity with the light emitting device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication module is placed inside the heat radiation frame, then the device structure is compact, but the signal reception performance is degraded due to wave shielding
Solution Approach 1:
The antenna is extracted from the interior of the heat radiation frame and positioned on its outer surface. This separation removes the antenna from the wave-shielding environment while maintaining the compact overall structure, thereby improving signal reception performance without significantly increasing device complexity
Solution Approach 2:
The heat radiation frame itself serves as an intermediary structure that hosts the antenna on its outer surface while the communication module remains inside. This intermediate positioning allows the antenna to access external signals without being shielded, while the frame maintains structural integrity and compactness
2Reliability
If the antenna is exposed outside the heat radiation frame, then the signal reception performance is improved, but the device structure becomes more complex
Solution Approach 1:
The heat radiation frame is designed to serve multiple functions: it provides thermal management for the LED, maintains structural support, and serves as a mounting platform for the antenna. This multi-functionality allows the antenna to be exposed outside for improved signal reception without adding separate structural elements, thereby avoiding increased device complexity
