Dual-Sided LED Linear Light Sealing Structure for Leakage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED linear lights face issues with light leakage due to the need for elastic margins between buckles, which compromise light utilization rates and lead to buckle breakage, necessitating new lamps when lighting requirements change.
Innovation Solution
A LED linear light design with hook-shaped portions and clamping grooves, combined with L-shaped inner end covers and magnets, ensures sufficient elastic margins while minimizing light leakage by allowing for deformation during installation, enhancing light utilization and service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If elastic margins are increased between buckles to allow deformation, then service life of buckles is improved, but gaps between lampshades and lamps become larger causing light leakage and reduced light utilization rate
Solution Approach 1:
The connection structure is divided into multiple components: buckles on the light-emitting member, sealing grooves on the buckles, clamping portions formed by inwardly extending inner wall surfaces, and corresponding clamping grooves on the lampshade. This segmentation allows each component to perform its specific function - the buckles provide mechanical connection with elastic margins for durability, while the sealing grooves and clamping portions work together to eliminate light leakage without requiring excessive elastic margins.
Solution Approach 2:
The sealing grooves act as intermediary elements between the buckles and the lampshade. These grooves receive and seal against the lampshade body, creating an effective light barrier. The clamping portions similarly serve as intermediaries that engage with clamping grooves to secure the lampshade while maintaining proper spacing. This intermediary mechanism allows the buckles to have sufficient elastic margins for deformation without creating harmful gaps that would cause light leakage.
2Loss of energy
If connections between lampshades and lamps are made tighter to reduce light leakage, then light utilization rate is improved, but elastic margins between buckles are reduced causing buckle blocks to break more easily
Solution Approach 1:
The connection system is segmented into distinct functional zones: the buckle blocks provide mechanical attachment with necessary flexibility, while separate sealing grooves and clamping mechanisms handle the light sealing function. This allows the buckle blocks to maintain adequate elastic margins for strength and deformation without compromising light utilization, as the sealing function is performed by dedicated sealing structures rather than relying on tight buckle-lampshade contact.
Solution Approach 2:
The sealing grooves and clamping portions serve as intermediary structures that achieve light sealing without requiring the buckle blocks themselves to be tightly compressed. The sealing grooves on the buckles engage with the lampshade body to prevent light leakage, while the clamping portions provide additional mechanical engagement. This intermediary mechanism protects the buckle blocks from excessive stress while ensuring effective light sealing.
3Device complexity
If a single lamp design is used for multiple environments, then device complexity is reduced, but adaptability to different lighting requirements deteriorates
Solution Approach 1:
The light-emitting member is designed as a universal component that can accommodate different lampshade types through standardized buckles with sealing grooves and clamping portions. The buckles can work with various lampshade designs (flat lampshades for store illumination, grille lampshades for glare reduction in office areas, or other specialized lampshades) while maintaining consistent mechanical and sealing interfaces. This allows a single light-emitting member design to serve multiple lighting applications by simply changing the lampshade accessory.
