HINS Lighting Control for Antimicrobial Dosage Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lighting systems using high intensity narrow spectrum (HINS) light struggle to consistently provide sufficient antimicrobial illumination, as they often operate in fixed modes without adjusting to user-defined dosage requirements or occupancy changes.
Innovation Solution
A method and system where control devices manage lighting systems to switch between modes based on user-defined dosages and occupancy, adjusting the intensity and duration of HINS and non-HINS light outputs to ensure sufficient antimicrobial spectral energy is maintained, using a blend of HINS and non-HINS light sources and feedback sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lighting systems operate in fixed modes with HINS light, then antimicrobial illumination is provided, but the systems cannot adjust to user-defined dosage requirements or occupancy changes
Solution Approach 1:
The lighting system transitions from fixed operational modes to dynamic, adjustable modes where HINS and non-HINS light sources can be independently controlled. The control device enables real-time adjustment of light intensity and duration based on user-defined dosage requirements and occupancy sensor feedback, allowing the system to adapt to varying antimicrobial needs while maintaining manageable complexity through modular control architecture.
2Reliability
If HINS light intensity is increased to ensure sufficient antimicrobial dosage, then microbial inactivation effectiveness improves, but energy consumption and potential harmful effects increase
Solution Approach 1:
The system applies partial action by using a blend of HINS and non-HINS light sources rather than relying solely on high-intensity HINS light. The control device calculates the required HINS light dosage and supplements it with non-HINS light to achieve the total required antimicrobial effect, thereby reducing the need for excessively high HINS light intensity while maintaining reliability of microbial inactivation.
Solution Approach 2:
The system changes operational parameters by dynamically adjusting the intensity and duration of HINS light based on real-time occupancy detection and dosage requirements. Rather than maintaining constant high intensity, the control device modulates HINS light parameters to deliver the precise dosage needed, reducing energy consumption and minimizing potential harmful effects of excessive exposure while ensuring antimicrobial effectiveness.
3Use of energy by moving object
If lighting system uses only HINS light for antimicrobial purposes, then spectral energy for microbial inactivation is maximized, but overall illumination quality and adaptability to user needs deteriorates
Solution Approach 1:
The lighting system achieves multi-functionality by integrating both HINS light sources for antimicrobial action and non-HINS light sources for general illumination. The control device coordinates these different light types to simultaneously provide microbial inactivation and user-customizable lighting environments, allowing the system to adapt to diverse user needs while maintaining efficient use of spectral energy for its primary antimicrobial function.

AI summary
A method for controlling operation of a lighting system is provided. The method includes operating the lighting system in a first mode during a time period to provide a first light output. The first output can be a blend of HINS light and non-HINS light. The method includes determining a dosage amount of HINS light provided during the time period. Furthermore, the method includes operating the lighting system in a second mode to provide a second lighting output. The second light output can be HINS light or a blend of HINS light and non-HINS light. Furthermore, spectral energy associated with HINS light in the second light output is greater than spectral energy associated with the HINS light in the first light output.
