Solution Overview

Problem

Existing lighting modules have limited flexibility and adaptability in terms of usage and installation space, particularly with conventional LED lighting solutions that require frequent replacement and suffer from decreased illuminance over time.

Innovation Solution

A lighting module design featuring a case with adjustable flanges, a light guide plate, luminescent films, a sub-reflector, and connectors that enhance optical efficiency and allow for various color combinations, enabling flexible installation and improved light distribution by preventing light reflection onto LEDs and using fluorescent materials in translucent resin to create white light.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional LED lighting modules are used, then electro-optic conversion efficiency and lifespan are improved, but adaptability to different installation spaces and usage scenarios is limited

Engineering Contradiction:
ImprovelifespanVSAvoidadaptability to installation space
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The lighting module is divided into separable components including a case with flanges, light guide plate, optical elements, and connectors. This segmentation allows the module to be adapted to different installation spaces by configuring the case and flanges in various arrangements while maintaining the core LED lighting function, thus resolving the contradiction between reliability and adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The case is designed with flanges that can be configured in multiple positions and orientations, enabling the same basic module structure to serve multiple installation scenarios (ceiling, wall, surface mounting). This multi-functionality approach allows the module to adapt to different spaces without compromising its reliable LED-based performance.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Illumination intensity

If light guide plate and optical elements are added, then light distribution and optical efficiency are improved, but device complexity increases

Engineering Contradiction:
Improvelight distributionVSAvoidstructure complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The light guide plate, diffuser, reflector, and protective cover are merged into a single integrated optical assembly that is placed within the case. This combining of multiple optical elements into one unified structure improves light distribution while minimizing the increase in device complexity, as the elements work together as a coordinated system rather than separate components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The optical elements are arranged in a layered configuration within the case, utilizing the vertical dimension to optimize light path management. The light guide plate distributes light horizontally while the diffuser and reflector manage vertical light propagation, creating efficient three-dimensional light distribution without significantly increasing horizontal footprint or structural complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If flanges are added to the case, then ease of installation and adaptability are improved, but manufacturing complexity increases

Engineering Contradiction:
Improveease of installationVSAvoidmanufacturing complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The flanges are pre-formed as integral parts of the case during the case manufacturing process, rather than being added as separate components during assembly. This preliminary action approach simplifies the overall manufacturing process by combining case and flange production into a single operation, while still providing the installation flexibility needed for ease of operation.

Inventive Principle:
Principle #10Preliminary action
