Solution Overview
Problem
Conventional emergency lighting devices lack an effective method to indicate specific locations within an area during power outages, which hinders efficient evacuation and rescue operations in emergency situations.
Innovation Solution
A system of lighting apparatuses forming a mesh network, each assigned with a unique identifier, illuminates colors or patterns to indicate its location, and communicates with a control center to facilitate location identification and life detection using CSI breathing and motion detection technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional emergency lighting devices are used during power outages, then illumination function is provided, but location indication capability is lacking
Solution Approach 1:
The emergency lighting device is designed to perform multiple functions: general illumination during power outages and specific location indication through color coding and patterns. By integrating both functions into a single device, the system provides comprehensive emergency guidance without requiring separate location indication devices, thus resolving the contradiction between providing location information and maintaining simple device structure.
Solution Approach 2:
The patent employs different colors and illumination patterns to encode location information and regional identifiers. Each lighting device displays specific color combinations or patterns that correspond to its geographic location and surrounding regions, enabling intuitive visual communication of location data without complex electronic displays or additional components.
2Measurement precision
If multiple lighting apparatuses are deployed to indicate locations, then location precision is improved, but system complexity increases
Solution Approach 1:
The system divides the service area into multiple regions, with each lighting apparatus responsible for indicating its own location and associated regions. This segmentation allows precise location identification through distributed devices while maintaining operational independence of each unit, reducing the complexity of centralized control systems.
Solution Approach 2:
Each lighting apparatus autonomously displays its location information and regional data without requiring complex external control or coordination. The devices independently manage their illumination patterns and color displays, eliminating the need for sophisticated communication protocols or centralized management infrastructure.
3Productivity
If color and pattern illumination is used for location indication, then information transmission efficiency is improved, but energy consumption increases
Solution Approach 1:
The lighting devices use periodic illumination patterns and color sequences to transmit location information efficiently. By encoding data in time-varying visual patterns rather than continuous multi-color display, the system achieves high information transmission efficiency while minimizing energy consumption through duty-cycled operation.

AI summary
A lighting apparatus and a system for indicating locations within an area are provided. The system includes a plurality of lighting apparatuses that are installed at different locations within the area. The lighting apparatuses form a mesh network. Every lighting apparatus is assigned with an identifier for locating the lighting apparatus with a color or a pattern. The lighting apparatus includes a control circuit that controls the lighting apparatus to operate with a first mode or a second mode. The apparatus includes a lighting unit that can be activated to illuminate color or pattern on a region for indicating where the lighting apparatus is located under the second mode. In an aspect, the area is divided into multiple regions that are indicated by different combinations of colors and patterns illuminated by the lighting units of the lighting apparatuses separately.
