Solution Overview
Problem
Current lighting configuration technologies in commercial settings, particularly those using LED lighting fixtures, lack the ability to perform initial configuration, fine tuning, and adaptation to specific features of the space, leading to inefficient and time-consuming processes.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional presence sensors and ambient light sensors are used to control lighting fixtures, then basic lighting control is enabled, but individual lighting fixtures and light sources cannot be configured or adjusted
Solution Approach 1:
The patent divides the lighting control system into individual addressable fixtures and even individual addressable light sources within fixtures. Each LED or group of LEDs can be independently controlled based on its spatial position and environmental conditions, allowing granular configuration without requiring a completely complex centralized system.
Solution Approach 2:
The system enables self-service configuration by using the existing sensor infrastructure (presence sensors and ambient light sensors) to automatically determine optimal lighting parameters for each fixture and light source. The system configures itself based on spatial measurements and environmental data without requiring manual intervention for each element.
2Manufacturing precision
If manual initial configuration and fine tuning of lighting fixtures is performed, then lighting requirements can be met, but the process is time consuming and not adapted to particular space features
Solution Approach 1:
The system uses presence sensors and ambient light sensors to provide real-time feedback about the spatial environment and occupancy patterns. This feedback is processed to automatically adjust lighting parameters for each fixture and light source, achieving precise configuration without manual intervention. The system continuously adapts based on sensor data about the actual usage of the space.
Solution Approach 2:
The patent replaces manual mechanical configuration processes with an automated optical sensing and computational system. Instead of manually measuring and adjusting each fixture, the system uses distance sensors, presence detectors, and ambient light sensors combined with processor-based algorithms to automatically determine optimal lighting configurations.
3Adaptability or versatility
If fixed lighting configuration is installed, then initial setup is completed, but the system cannot adapt to changes in layout and usage of the space
Solution Approach 1:
The lighting configuration is made dynamic rather than static. Each lighting fixture and light source can independently adjust its parameters in real-time based on changing conditions detected by sensors. The system responds to layout changes and usage pattern changes automatically, with lighting parameters being continuously optimized rather than fixed during installation.
Solution Approach 2:
The system performs preliminary configuration actions automatically during installation by measuring spatial relationships and initial environmental conditions. This preliminary setup establishes baseline parameters that are then automatically adjusted as the system operates, eliminating the need for subsequent manual reconfiguration when space usage changes.
