Solution Overview
Problem
There is a challenge in finding a lighting apparatus that balances cost, light efficiency, flexibility, and ease of component replacement while maintaining a thin design suitable for various environments, with existing solutions struggling to meet these requirements effectively.
Innovation Solution
The proposed lighting apparatus consists of a driver, bottom cover, light source module, lens module, light passing cover, and base plate, featuring a modular design with central openings for easy assembly and detachability, heat dissipation, and the use of multiple LED modules with diffusion lenses on a transparent plastic plate, along with a buckle structure for component fixation and easy replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a thin design is implemented for the lighting apparatus, then the form factor and adaptability are improved, but the heat dissipation capability deteriorates
Solution Approach 1:
The lighting apparatus is divided into multiple functional modules: a driver module housed in a driver container, a light source module with LED chips, a lens module with diffusion lenses, and a light passing cover. This segmentation allows each module to be optimized independently - the thin overall design is maintained while heat dissipation pathways are engineered within specific modules (e.g., heat dissipation structures in the base plate or driver container)
Solution Approach 2:
A lens module with multiple diffusion lenses is introduced as an intermediary between the LED light sources and the external environment. This lens module not only distributes light uniformly but also serves as a thermal management interface, allowing heat to be dissipated through the lens structure while maintaining the thin profile of the overall apparatus
2Illumination intensity
If multiple LED modules are used to improve light output and efficiency, then the illumination quality is improved, but the device complexity increases
Solution Approach 1:
Multiple LED chips are mounted on a single light source module, and multiple diffusion lenses are integrated into one lens module. This merging approach allows the system to achieve high light output through multiple LEDs while reducing overall complexity by consolidating control and structural elements. The driver module provides unified control for all LED chips, simplifying the electrical architecture despite having multiple light-emitting elements
Solution Approach 2:
The lens module serves multiple functions simultaneously: it distributes light uniformly across the light passing cover, protects the LED modules, and acts as a structural element that maintains the thin design. This multi-functionality reduces the need for separate components, thereby reducing device complexity while maintaining high illumination quality
3Ease of repair
If modular design with detachable components is implemented, then the ease of repair and maintenance is improved, but the device complexity increases
Solution Approach 1:
The lighting apparatus is segmented into distinct modules (driver module, light source module, lens module, light passing cover) that can be independently removed and replaced. Each module is designed with standardized connection interfaces, allowing for easy maintenance and repair without requiring disassembly of the entire apparatus. This modular segmentation directly improves ease of repair while the standardized interfaces help control the increase in device complexity
4Ease of operation
If central openings are provided for assembly and detachability, then the ease of operation is improved, but the structural strength deteriorates
Solution Approach 1:
The central openings in the light passing cover, driver container, and base plate are designed with nested alignment features. The openings are positioned and sized to work together as a aligned pathway, with each component's opening nested within the overall assembly pattern. This nesting approach allows for easy assembly and disassembly through the central openings while maintaining structural strength through the interlocking nature of the nested design

AI summary
A lighting apparatus includes a driver, a bottom cover, a light source module, a lens module, a light passing cover and a base plate. The bottom cover has a first central opening a driver container for storing the driver. The light source module has multiple LED modules and a second central opening. The lens module has a third central opening and multiple diffusion lenses respectively placed above the multiple LED modules. The lens module is fixed to the bottom cover to make the light source module, the driver, the lens module and the bottom cover as a portable module. The first central opening, the second central opening and the third central opening together form a main central opening. The base plate may be fixed to an installation platform.
