Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LED lamp tubes require separate purchasing based on different launching specifications for electronic and inductor rectifiers, leading to a lack of compatibility and unified standards, making it impossible for a single tube to function with both types of rectifiers.
Innovation Solution
The LED lamp tube incorporates conductive pin assemblies, a polarity conversion module, a suppressor, and a voltage buck-booster module, including capacitors and bridge rectifiers, to stabilize and convert voltages, allowing compatibility with both electronic and inductor rectifiers and preventing damage from surge voltages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional LED lamp tubes are designed for specific rectifier types (electronic or inductor), then they can function reliably with that rectifier type, but they cannot be compatible with both rectifier types and require separate purchasing
Solution Approach 1:
The LED lamp tube incorporates a dual rectifier circuit design that includes both electronic rectifier components (bridge rectifier, capacitors) and inductor rectifier components (inductor, starter), enabling a single lamp tube to function with both electronic and inductor-based rectifiers, thereby achieving universal compatibility across different rectifier types
Solution Approach 2:
The circuit is divided into separate functional modules: electronic rectifier module (bridge rectifier, capacitors), inductor rectifier module (inductor, starter), and LED driving module. This segmentation allows each module to be independently activated based on the rectifier type, reducing overall complexity while maintaining versatility
2Reliability
If voltage stabilization components are added to the LED lamp tube, then voltage stability is improved, but the device complexity increases
Solution Approach 1:
The voltage stabilization function is merged with the existing rectifier circuitry by integrating capacitors into the bridge rectifier circuit and using the inductor as both a rectifier component and a voltage stabilization element. This combination approach provides voltage stabilization without adding completely separate stabilization circuits, thereby limiting the increase in device complexity
