LED Street Lamp Mounting Shell Detachable Cover Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED street lamps face challenges in maintaining the power supply, as it is integrated and sealed within the shell, making replacement inconvenient, especially when the lamps are installed high, and the hinge mechanism is exposed, compromising the integrity of the lamp.
Innovation Solution
A mounting shell design with a clamping slot and fixer mechanism allows for easy detachment and reattachment of the cover, preventing exposure of the clamping connector and facilitating power supply replacement without damaging the lamp's integrity, while a sealing ring enhances moisture protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power supply is integrated and sealed within the shell, then the lamp's integrity and protection are improved, but the ease of maintenance and replacement of the power supply deteriorates
Solution Approach 1:
The mounting shell is segmented into a shell body and a detachable cover. The cover can be separated from the shell to provide access to the power supply, while the shell body maintains structural integrity. This segmentation allows the power supply to be replaced without damaging the overall lamp structure.
Solution Approach 2:
The power supply is extracted as a separate replaceable component within the mounting shell. The cover can be detached to access and remove the power supply, allowing maintenance without affecting the shell's integrity. The power supply is taken out for replacement and then reinserted when the cover is reclosed.
2Ease of operation
If the cover is connected through an exposed hinge mechanism, then the ease of operation for opening/closing is improved, but the aesthetic integrity and completeness of the lamp deteriorates
Solution Approach 1:
The hinge mechanism is extracted from the external view and relocated inside the mounting shell. The cover connects to the shell through this internal hinge, allowing the cover to be opened and closed while remaining hidden from external view, thus maintaining the lamp's aesthetic integrity.
Solution Approach 2:
The hinge mechanism is nested within the mounting shell structure. The hinge is positioned inside the shell body, allowing the cover to pivot while the hinge itself remains concealed within the overall lamp structure, preserving the external appearance.
