Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing track lighting systems that incorporate LEDs for both illumination and disinfection purposes often expose individuals to direct disinfection light, posing safety concerns.
Innovation Solution
A track lighting system with a power track and two LED modules, where the first module provides omnidirectional illumination and the second module, with a fixed collimator angle for disinfection, is oriented to limit direct exposure of disinfection light to individuals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a track lighting system is arranged in a ceiling to provide disinfection lighting, then disinfection effectiveness is improved, but persons in the space are directly exposed to disinfection light which is harmful
Solution Approach 1:
The lighting system is divided into separate functional modules: a first LED module for illumination and a second LED module for disinfection. Each module can be independently positioned and oriented on the track, allowing the disinfection module to be directed toward the ceiling while the illumination module provides downward lighting, thus resolving the contradiction between disinfection effectiveness and safety.
Solution Approach 2:
Different regions of the lighting system are assigned different functional properties. The second LED module is specifically oriented to direct disinfection light upward toward the ceiling where it can effectively disinfect surfaces without exposing persons below. The first LED module maintains omnidirectional illumination properties. This local differentiation of function and orientation resolves the harmful exposure issue while preserving disinfection effectiveness.
2Adaptability or versatility
If a track lighting system provides both illumination and disinfection functions, then versatility is improved, but device complexity increases
Solution Approach 1:
The track lighting system is designed with modular LED modules that can perform multiple functions. The same track structure supports both illumination modules and disinfection modules, and each module type can be independently selected and positioned. This universal track design with specialized modules achieves dual functionality without proportionally increasing overall system complexity.
Solution Approach 2:
The system employs adjustable and reconfigurable elements including tiltable collimators and rotatable modules that allow dynamic optimization of light distribution. The first collimator can be tilted to adjust illumination angles, while the second collimator is fixed at a specific angle for optimal disinfection. This dynamic adjustability provides versatility while maintaining manageable complexity through standardized adjustment mechanisms.
