Solution Overview
Problem
Conventional LED lighting systems do not effectively mitigate intense light emission, leading to eye strain and discomfort, and lack versatility in light distribution patterns.
Innovation Solution
A lighting module comprising a light guide plate with a top and bottom surface, covered by cases on either side, featuring distinct light sources and extension parts, which emit light through differently sized openings to control light distribution and reduce intensity, using a substrate and light emitting devices to create a balanced and adjustable lighting effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If LED lighting apparatus uses direct lighting to maintain high conversion efficiency and low power consumption, then energy efficiency is improved, but light intensity becomes too strong causing eye strain and discomfort
Solution Approach 1:
The lighting apparatus is divided into multiple lighting modules, each containing separate first and second light sources that emit light in different directions (first light and second light). This segmentation allows independent control of light paths and intensities, enabling the system to maintain high energy efficiency while reducing the harmful intensity of direct light through the light guide plate.
2Object-affected harmful factors
If LED lighting apparatus uses indirect lighting to mitigate intensified light emission, then eye comfort is improved, but light conversion efficiency decreases
Solution Approach 1:
Different regions of the lighting apparatus have different light emission characteristics. The first light source emits light through one side of the light guide plate while the second light source emits light through the other side, creating locally optimized light distribution. This allows areas requiring direct lighting to maintain efficiency while areas requiring comfort use indirect lighting paths.
Solution Approach 2:
The lighting apparatus uses asymmetric light emission by positioning light sources on opposite sides of the light guide plate, with each emitting light in different directions. This asymmetric configuration enables the system to simultaneously achieve high energy efficiency through direct light paths and improved eye comfort through indirect light paths, resolving the contradiction between the two requirements.
3Device complexity
If conventional LED lighting systems use uniform light distribution to simplify design, then device complexity is reduced, but versatility in light distribution patterns is limited
Solution Approach 1:
The lighting apparatus enables dynamic control over light distribution patterns by independently adjusting the first and second light sources. Users can switch between different lighting modes (first light only, second light only, or both combined) to create various light distribution patterns, providing versatility without significantly increasing device complexity.
