Linear Lighting Module Coupling and Corner Connection Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing linear lighting devices face challenges in simplifying the coupling and separation of installation rails and lighting modules, leading to complex electrical connections and potential electrical hazards, especially at corners where angle mismatches can occur, resulting in uneven illumination and increased risk of electrical accidents.
Innovation Solution
A linear lighting device design featuring a housing with an accommodating space for the lighting module, where the power supply terminal is insulated and the power connection terminal is elastically supported, allowing for easy coupling and decoupling of modules and flexible angular connections between housings, reducing the risk of electrical shocks and simplifying maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bar type LED lighting module with socket on side surface is used, then linear illumination can be configured, but all lighting modules from outermost to corresponding module need to be separated to replace a single module
Solution Approach 1:
The lighting system is divided into independent modular units, each with its own power connection capability. The socket structure is redesigned so that each module can be independently connected and disconnected without affecting adjacent modules, enabling individual module replacement while maintaining continuity of the overall lighting system.
2Ease of manufacture
If corner members with fixed angles (60, 90, 120 degrees) are used to connect installation rails, then the rails can be connected at corners, but the lighting device must be disposed according to the corner member angle
Solution Approach 1:
The corner member is designed with adjustable and flexible connection mechanisms that allow the installation rails to be connected at various angles, not just fixed angles. The structure enables dynamic adjustment of the connection angle to match different architectural requirements while maintaining stable electrical and mechanical connections.
3Ease of manufacture
If installation rails are slantly cut and wired on site to connect power supply terminals, then the rails can be connected at corners, but the installation process becomes complicated and execution becomes difficult
Solution Approach 1:
The corner members are pre-manufactured with integrated power supply terminals and wiring connections before installation. This preliminary preparation eliminates the need for on-site slant cutting and complex wiring operations, significantly simplifying the installation process while ensuring reliable electrical connections between installation rails at corner positions.
4Adaptability or versatility
If LED lighting modules use existing fluorescent lamp coupling structures, then they can replace fluorescent lamps, but the rotation and insertion method creates inconvenience and uneven illuminance levels
Solution Approach 1:
Instead of making the lighting module rotate and insert into the socket, the design inverts the coupling mechanism so that the socket remains stationary and the lighting module is directly coupled in a straightforward manner. This inversion eliminates the inconvenient rotation operation while maintaining compatibility with existing fluorescent lamp fixtures.
