Solution Overview
Problem
Existing LED lamps lack a convenient and efficient mechanism for quickly disassembling and assembling lenses, which hinders the replacement and adjustment of optical systems for varying light field distribution requirements.
Innovation Solution
An LED lamp design featuring a quick disassembling structure with an elastic sheet for easy lens replacement, a rotating assembly for adjusting light distribution, and a power supply assembly with heat separation to enhance service life, along with sealing rings for waterproofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional fixed lens structure is used in LED lamps, then the structural stability is maintained, but the ease of lens replacement deteriorates
Solution Approach 1:
The lens assembly is segmented into a lens panel and a holder, which can be separated from each other. The holder is further divided into a body portion and a clamping portion that can move relative to the lens panel. This segmentation enables independent replacement of the lens panel while keeping the holder structure, simplifying the replacement process.
Solution Approach 2:
The clamping portion is designed to move between a clamping state (when elastic sheet is pressed) and a released state (when elastic sheet returns to original position). This dynamic mechanism allows the lens panel to be easily inserted and secured without complex fastening operations, improving replacement convenience while maintaining structural stability.
2Adaptability or versatility
If multiple lenses are used for different light field distributions, then the adaptability is improved, but the time required for lens replacement increases
Solution Approach 1:
The lens panel is extracted as an independent replaceable component from the overall lamp structure. The elastic sheet mechanism provides a quick release function that allows the lens panel to be removed without disassembling the entire lamp housing or using special tools, significantly reducing replacement time.
Solution Approach 2:
The elastic sheet automatically returns to its original position after being pressed, which automatically restores the clamping force to secure the lens panel. This self-service mechanism eliminates the need for additional fastening operations or tools, enabling users to quickly replace lenses themselves without professional assistance.
3Reliability
If the lens is tightly fixed to the lamp body, then the reliability of connection is improved, but the ease of disassembly deteriorates
Solution Approach 1:
The elastic sheet is pre-compressed during assembly to create immediate clamping force on the lens panel, ensuring reliable connection from the start. When replacement is needed, pressing the elastic sheet temporarily releases this pre-applied force, allowing easy removal. After release, the elastic sheet automatically restores its compression, ready for the next lens installation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and tool-free lens replacement, adjustable light distribution, and improved durability and waterproofing, enhancing the usability and performance of LED lamps.
Implementation Method 1
The quick disassembling structure is an elastic sheet, the lens panel is provided with a through hole corresponding to the elastic sheet, an end of the elastic sheet is fixed to the lamp body, another end of the elastic sheet extends outward transversely and away from the LED lamp panel through the through hole
Implementation Method 2
The rotating assembly is movably connected to the moving member. The lens panel is provided with a connecting portion movably connected to the moving member. The moving member is driven to move by rotating the rotating assembly, and the moving member drives the lens panel to move through the connecting portion, so that a distance between the lens panel and the LED lamp panel is changed, thereby adjusting the light distribution direction.
