Independent LED Lamp Bead Drive Circuit for Series Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Symphony point-controlled lamp beads are connected in series, leading to issues where a damaged bead can disrupt the entire series, requiring complex packaging and poor adaptability, as signal connections need to be welded between each bead.
Innovation Solution
The LED lamp bead operates independently with a drive circuit that receives a trigger signal, allowing each bead to emit light without relying on neighboring beads, featuring a drive circuit with an input pin, power supply pins, and a light-emitting body control chip to ensure each bead functions normally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LED lamp beads are connected in series for signal control, then signal communication between beads is achieved, but the system reliability deteriorates because a damaged bead can disrupt the entire series connection
Solution Approach 1:
The patent divides the signal control system into independent segments by giving each LED lamp bead its own drive circuit that can process control signals autonomously. This segmentation allows each bead to operate independently while maintaining series connection for power, thus improving reliability without requiring complex inter-bead signal wiring.
Solution Approach 2:
The patent combines the signal input and drive circuit functionality into each individual LED lamp bead unit. By merging these functions at the bead level rather than requiring separate signal wiring between beads, the system achieves reliable independent operation while simplifying the overall connection structure.
2Adaptability or versatility
If welding pin brackets are arranged at signal input and output ends with signal output line welding, then signal communication between adjacent beads is achieved, but the packaging complexity increases and adaptability deteriorates
Solution Approach 1:
The patent merges the signal processing functionality into each bead's drive circuit, eliminating the need for separate signal input and output焊接 pin brackets. This integration simplifies the packaging structure and improves adaptability since each bead can be controlled independently without complex interconnections.
Solution Approach 2:
The patent extracts the signal communication requirement from the physical connection between beads. By using wireless or integrated signal processing within each bead, the complex welding pin bracket structure is removed, simplifying manufacturing while maintaining lighting adaptability.
