LED Floor Lighting for Social Distance Marking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a system that effectively communicates and maintains social distancing guidelines in enclosed spaces, as existing methods lack a clear and visible means to demarcate safe distances among individuals.
Innovation Solution
A social distance lighting system that projects an illuminated grid onto a floor using a lamp with LEDs, where boundary LEDs mark the edges of cells and centering LEDs indicate the center points, allowing individuals to maintain proper social distance, controlled by a remote control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If social distancing guidelines are communicated using traditional methods (signs, verbal instructions), then the system is simple and easy to implement, but the visibility and clarity of distance demarcation is insufficient
Solution Approach 1:
The patent replaces traditional mechanical or static visual aids (signs, painted markers) with an optical system using LEDs and projectors to dynamically illuminate social distancing markers on the floor. This substitution provides superior visibility through controlled illumination while maintaining operational simplicity through remote control
Solution Approach 2:
The system uses different colored LEDs (red, green, blue) to indicate different social distancing zones and statuses. The color changes provide immediate visual feedback to users about their position relative to safe distancing boundaries, enhancing visibility and understanding without complex mechanical components
2Loss of information
If illuminated markers are projected onto the floor, then clear visual demarcation of social distancing zones is achieved, but energy consumption increases
Solution Approach 1:
The system employs periodic illumination rather than continuous lighting, where LEDs are activated in sequences or cycles to indicate different zones. This periodic action maintains clear visual communication of social distancing requirements while significantly reducing overall energy consumption compared to continuous illumination
Solution Approach 2:
The system illuminates only the specific zones and markers that are currently relevant to occupied areas, rather than lighting up the entire space continuously. This partial action approach ensures clear communication of distancing boundaries while minimizing energy waste in unoccupied or less critical areas
3Measurement precision
If multiple LEDs are used to mark boundaries and center points, then precision of social distance demarcation is improved, but device complexity increases
Solution Approach 1:
The system divides the floor space into discrete zones marked by individual LEDs positioned at boundaries and center points. Each LED represents a specific measurement point, providing precise demarcation of social distancing zones. The segmentation allows for accurate spatial definition while keeping each individual component simple and standardized

AI summary
The social distance lighting system generates an illuminated image. The social distance lighting system is configured for use with the floor of a chamber. The floor is the inferior horizontally oriented supporting surface of the chamber. The illuminated image projected by the social distance lighting system presents indicia on the floor of the chamber. The indicia presented by the social distance lighting system generates a sentiment that marks the boundaries and center points that allow people to maintain a proper social distance. The social distance lighting system comprises a lamp, a plurality of LEDs, and a remote control. The plurality of LEDs mount in the lamp. The plurality of LEDs generate the illuminated image. The remote control controls the operation of the plurality of LEDs.
