Solution Overview

Problem

Conventional light source modules suffer from light loss due to assembly tolerances and spatial configurations, which affect their efficiency and brightness.

Innovation Solution

The proposed light source module incorporates multiple light sources and reflective layers that reflect light back to the sources, forming an integral structure to reduce light loss and enhance brightness by recycling light within the module.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If conventional light source modules are used with standard optical components, then the structure is simple and easy to manufacture, but light loss occurs due to assembly tolerances and spatial configurations

Engineering Contradiction:
Improvelight lossVSAvoidstructure complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent merges multiple light sources and reflective layers into an integrated assembly where components are positioned to work together as a unified system. The reflective layers are incorporated directly into the light source module structure, combining functions of light generation and light management in a single integrated component rather than separate assemblies.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The reflective layers act as intermediary elements between the light sources and the external environment. These layers mediate the light path by reflecting light that would otherwise be lost, redirecting it back toward the optical output path and improving overall light efficiency without requiring complex external optical systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Illumination intensity

If conventional light source modules are used without light recycling, then the device complexity is low, but the brightness and efficiency are reduced due to unrecycled light loss

Engineering Contradiction:
ImprovebrightnessVSAvoidstructural complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The reflective layers enable continuous useful action by continuously reflecting unutilized light back into the optical path. This creates a sustained light recycling process where light that would normally be lost is continuously redirected and reused, maintaining high brightness levels throughout operation without interruption or additional energy input.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The patent recovers light that would otherwise be discarded or lost from the system. The reflective layers capture and redirect light that escapes from the light sources, recovering this energy and redirecting it back into the useful optical path, thereby improving brightness without requiring additional light sources or energy input.

Inventive Principle:
Principle #34Discarding and recovering
