Solution Overview
Problem
Existing LED light fittings are complicated to install and remove due to screw-based mounting systems, which can lead to misalignment and damage, and are inconvenient for maintenance, especially in applications requiring high protection class and closed structures.
Innovation Solution
An integrated LED light source module strip that can be easily plugged and unplugged from the light fitting casing through a through-hole, eliminating the need for unscrewing screws and allowing for tool-free maintenance, with a sealing part to secure the connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw-based mounting system is used to fix LED light source on light fitting casing, then the connection strength and reliability are improved, but the installation complexity and time consumption increase significantly
Solution Approach 1:
The invention divides the light source assembly into a modular unit (light source + mounting plate + sealing plate) that can be independently assembled and installed as a single component. This segmentation allows the complex screw-based connection to be simplified to a single insertion operation through the through-hole, while maintaining reliable electrical and mechanical connections through the modular design.
Solution Approach 2:
The invention extracts the mounting function from the traditional screw-based system and integrates it into a dedicated mounting plate with positioning structures. The mounting plate includes positioning holes and sealing structures that are extracted and combined into a unified component, allowing the light source to be mounted and sealed through a single insertion action rather than multiple screw operations.
2Strength
If multiple screws are used to secure LED light source, then the fixing strength is improved, but the risk of installation misalignment and damage increases
Solution Approach 1:
The mounting plate is pre-equipped with positioning holes and sealing structures before installation. The positioning holes are precisely formed in advance to guide the insertion of the light source module, ensuring proper alignment. The sealing plate is also pre-assembled with the mounting plate, so that both mechanical fixation and sealing functions are prepared beforehand, eliminating the need for complex alignment operations during installation and reducing the risk of damage.
3Stability of the object's composition
If traditional screw mounting is used, then the structural stability is improved, but the ease of maintenance and removal deteriorates
Solution Approach 1:
The invention transforms the static screw-based fixation system into a dynamic insertion-removal system. The light source module can be easily inserted through the through-hole and fixed by the positioning structures, and equally easily removed by reversing the insertion process. This dynamic design maintains structural stability during operation while enabling quick maintenance without tools, as the modular design allows for tool-free installation and removal.
4Reliability
If closed light fitting casing structure is adopted for high protection class, then the protection class is improved, but the ease of installation and maintenance deteriorates
Solution Approach 1:
The invention extracts the sealing and mounting functions from the closed casing structure and integrates them into the modular light source assembly. The mounting plate and sealing plate are pre-assembled with positioning holes and sealing structures that align with corresponding features in the casing. This allows the light source module to be installed through a through-hole in the casing without requiring the casing to be opened or disassembled, maintaining the closed protective structure while enabling easy installation and maintenance.

AI summary
A kind of LED light fitting facilitating assembly and disassembly includes a light fitting casing and a light source module strip installed therein. The light source module strip is in one integral structure that can be assembled and disassembled independently in the LED light fitting. The integral structure includes a LED light source and a LED light source installation base. The LED light source installation base is an elongate profile. The light source module strip is inserted into the light fitting casing through a through-hole and fixed with the light fitting casing. The through-hole is sealed with a sealing part. The LED light fitting provided by the present invention can be installed and remove conveniently by simple plugging and unplugging, neither needing to open the light fitting casing with a relatively large volume nor needing to unscrew a lot of screws using dedicated tools. As a result, the operating procedure is further simplified, and the light fitting becomes more simple and convenient in installation and removal.
