Lamp Power Adapter Terminal Layout for Three LED Lusters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamp power adapters are limited in the number of LED lamp lusters they can connect, resulting in restricted light effects and increased material costs due to unnecessary shell components.
Innovation Solution
The lamp power adapter is enhanced by adding a third output connecting terminal and conductive component, allowing for the connection of three LED lamp lusters, and optimizing the shell design by reducing the length of ribs, thereby reducing material usage and costs.

Engineering Contradiction Analysis
1Adaptability or versatility
If two output connecting terminals are arranged on the power adapter, then the structure is simple, but the quantity of lamp luster connected is limited to two
Solution Approach 1:
The output connecting terminals are segmented into multiple independent terminals (first, second, and third output connecting terminals), each capable of connecting to separate conductive components and lamp lusters. This segmentation allows the power adapter to support more lamp lusters while maintaining a relatively simple overall structure by using modular terminal designs.
2Reliability
If the length of ribs is made equal to or slightly less than the length of the circuit board, then the circuit board is properly supported and limited, but more materials are required during injection molding, increasing shell cost
Solution Approach 1:
The ribs are designed with a length that is partial rather than equal to the circuit board length (e.g., 60-70% of the circuit board length). This partial action provides sufficient support and limitation for the circuit board during operation while significantly reducing the amount of material required for injection molding, thereby lowering shell cost without compromising reliability.
