LED Lamp Communication Board Signal Interference Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart LED lamps experience signal interference between LED modules and communication modules, leading to poor communication performance due to their physical arrangement.
Innovation Solution
The LED lamp design separates the LED module and driving module by the top housing, with the communication board extending through the driving box, top housing, and LED module to the light transmitting cover, reducing signal interference and masking effects, and includes a heat sink and waterproof structure for improved performance and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the communication board is connected to the driving board with LED modules disposed above it, then the structure is compact and easy to manufacture, but the LED modules generate signals that interfere with the communication module operation
Solution Approach 1:
The communication board is extracted from the driving board and extended through the top housing and LED module toward the light transmitting cover. This separation removes the communication module from the interfering electromagnetic environment of the LED modules while maintaining structural integration, thereby improving communication reliability without sacrificing manufacturing ease
Solution Approach 2:
The top housing and LED module serve as intermediary structures through which the communication board extends. These components act as mediators that allow the communication board to physically separate from the driving board while maintaining electrical connections, enabling the communication module to operate away from interfering signals
2Reliability
If the communication board is extended through the top housing and LED module toward the light transmitting cover, then signal interference is reduced and communication performance is improved, but the device structure becomes more complex
Solution Approach 1:
The communication board serves multiple functions: it provides electrical connections for communication, acts as a structural support element, and enables the modular assembly of different components. By making the communication board multi-functional, the design reduces the need for additional separate components, thereby improving communication performance while limiting the increase in overall structural complexity
