LED Module Load Variation for Parameter Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED module and converter systems require additional components, connections, or interaction to transmit operating parameters, leading to increased costs and reduced compactness due to the need for separate communication lines and additional components.
Innovation Solution
The system utilizes load changes in the LED module to transmit information to the LED converter through a time-limited starting phase or bidirectional communication, where the LED module represents a varying power load within a specific voltage window, allowing the LED converter to detect and decode operating parameters without additional connections or interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional components or connections are used to transmit operating parameters, then information transmission reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges the power supply function and communication function into a single channel. The existing power supply connections are used to transmit both electrical energy and operating parameter information, eliminating the need for separate communication lines and reducing device complexity while maintaining information transmission reliability
Solution Approach 2:
The power supply connections are given multiple functions: they serve both as energy transmission paths and as communication channels for transmitting operating parameters from the LED module to the LED converter. This multi-functionality reduces the number of components needed
2Reliability
If additional components are used to transmit operating parameters, then information transmission is improved, but manufacturing cost increases
Solution Approach 1:
The patent combines communication functionality with existing power supply infrastructure, eliminating the need for additional communication components. This reduces part count, simplifies assembly, and lowers manufacturing costs while ensuring reliable parameter transmission
Solution Approach 2:
The system uses its own power supply connections to carry out the communication function, making the system self-sufficient. No external communication infrastructure or additional components are required, reducing manufacturing complexity and cost
3Reliability
If additional connections are used to transmit operating parameters, then communication reliability is improved, but compactness is reduced
Solution Approach 1:
The patent merges communication and power supply functions into the same physical connections, eliminating the need for separate communication lines. This maintains communication reliability while preserving the compact design by avoiding additional connection paths
