Solution Overview
Problem
Existing lighting fixtures face inefficiencies due to glare and spill issues, as they often require high light intensity and wide light distribution, leading to resource wastage and increased costs from excessive light pole and fixture usage.
Innovation Solution
A modular lighting fixture system with interchangeable light engine modules, each comprising light emitting diodes, allows for customizable light distribution patterns by varying the number and orientation of modules on a post, minimizing spill and glare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If high light intensity is used to maintain given light level at distant target area, then illumination quality is improved, but glare problems increase
Solution Approach 1:
The lighting system is divided into multiple independently controllable light engine modules that can be selectively activated. This allows the light to be distributed in controlled patterns across the target area, maintaining adequate illumination while directing light away from viewer positions to minimize glare.
Solution Approach 2:
The system enables dynamic control of light distribution by allowing selective activation and orientation adjustment of individual light engine modules. This dynamic capability permits optimization of light patterns in real-time to maintain illumination quality while reducing glare for viewers in different positions.
2Area of stationary object
If diverging or converging beams are used to cover large target area, then illumination coverage is improved, but light spill increases
Solution Approach 1:
The lighting system divides the overall illumination task into multiple discrete light engine modules, each capable of producing controlled light patterns. This segmentation allows precise control over light distribution across the target area, covering large surfaces while minimizing light spill to unwanted areas through selective module activation and orientation.
Solution Approach 2:
Each light engine module can be independently oriented and controlled to provide localized light distribution patterns tailored to specific areas of the target zone. This local quality control enables optimized illumination coverage while preventing light spill to adjacent areas that should remain darker.
3Manufacturing precision
If more light poles and fixtures are used to improve lighting control, then lighting precision is improved, but system cost and resource consumption increase
Solution Approach 1:
The light engine modules are designed as universal, multi-functional units that can be selectively activated in different orientations and configurations. This multi-functionality allows a single module type to provide various light distribution patterns, eliminating the need for multiple specialized fixtures and reducing the total number of light poles and fixtures required while maintaining precise lighting control.
Solution Approach 2:
The system employs dynamic control capabilities of individual light engine modules to achieve precise lighting patterns without requiring additional fixtures. Through selective activation and orientation adjustment, the modules can adapt to different lighting requirements, reducing the overall quantity of fixtures needed while maintaining lighting precision.
