Spliced Lighting Fixture Modular Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fan lamps have non-modularized light-emitting parts, making them difficult to disassemble, transport, and install, and the interaction between fan and lamp functions compromises their individual performance.
Innovation Solution
A spliced lighting fixture with modular luminous modules, each comprising a luminous frame unit and a connecting rod, allowing for independent operation of fan and lamp functions without mutual interference, and featuring a polycarbonate arcuate housing for cost-effectiveness and adjustable illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an integrated molded housing is used for the light-emitting part, then the structure is simple and easy to manufacture, but the housing is easy to deform and has a wide and thick light-emitting surface, resulting in large volume and high packaging/transportation cost
Solution Approach 1:
The light-emitting part is divided into multiple independent luminous modules, each with its own housing and light-emitting components. This segmentation allows each module to be compact and efficiently packaged, reducing overall volume while maintaining manufacturing simplicity through standardized modular units.
2Device complexity
If an integrated all-plastic fan lamp is used, then the structure is simple, but it presents a large volume, high packaging cost and high transportation cost
Solution Approach 1:
The fan lamp is segmented into separate functional modules (fan module, lighting module, mounting base) that can be independently packaged and transported. This reduces the packaging volume and cost compared to a single integrated plastic housing, while maintaining relative structural simplicity.
3Illumination intensity
If the light diffusion plate is fully covered over the bearing wall and air outlet is arranged at the periphery, then the ratio of luminous area is improved and luminous flux is improved, but the fan ventilation hole can only operate in an annular air outlet manner and air inlet hole is small, weakening the fan function
Solution Approach 1:
The lighting and fan functions are segmented into separate modules with independent air inlet and outlet openings. The lighting module has its own light-emitting components and diffusion plates, while the fan module has dedicated ventilation openings, allowing both functions to operate independently without mutual interference.
Solution Approach 2:
The fan's air inlet and outlet openings are extracted from the lighting module structure and positioned in the fan module. This extraction allows the fan to have adequate ventilation areas without being constrained by the lighting module's light-emitting surface requirements, thus maintaining strong fan function while achieving high luminous flux.
4Ease of operation
If modularization is applied to simplify installation, then installation convenience is improved, but the structure of actual product is still large and not convenient for transportation
Solution Approach 1:
The lighting fixture is divided into compact luminous modules that can be easily assembled and disassembled for installation and transportation. Each module is designed to be space-efficient, reducing overall product volume while maintaining installation convenience through standardized connection interfaces.

AI summary
A spliced lighting fixture has a mounting base and at least two luminous modules. Each of the at least two luminous modules includes a luminous frame unit and a connecting rod, and the luminous frame unit is spliced on the mounting base through a terminal of the connecting rod. All of luminous frame units are arranged in multi-segment arcs on a concentric circle. All of the luminous frame units are connected end to end to form a circle, so that all of the luminous frame units form a whole annular luminous frame. The luminous frame unit includes a luminous frame unit bracket, an arcuate housing which is matched and connected with the luminous frame unit bracket, and luminous members which are arranged in the arcuate housing and distributed at intervals. The spliced lighting fixture is composed of two or more luminous modules spliced together.
