Wireless Mesh Lighting Relay for Channel Switching Signal Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless mesh lighting systems, communication reliability is compromised due to signal unreceptivity issues when channels are switched, leading to communication troubles and decreased reliability in receiving signals from lighting apparatuses to a terminal.
Innovation Solution
A lighting apparatus with a communication circuit and controller establishes a connection with a terminal, intercepts and retransmits signals from other lighting apparatuses via wireless communication, ensuring reliable signal transfer through connection-oriented communication methods, even when channels are switched.

Engineering Contradiction Analysis
1Adaptability or versatility
If the receiver repeatedly switches between multiple channels to receive signals, then the receiver can potentially receive signals on different channels, but the receiver may be in a state where no signal is receivable depending on channel switching timing, causing communication troubles and decreasing communication reliability
Solution Approach 1:
The patent introduces a relay lighting apparatus as an intermediary device in the communication path. When the terminal transmits a signal, the relay lighting apparatus receives it and retransmits it to the target lighting apparatus. This intermediary approach ensures that even if channel switching causes the terminal to miss the response signal from the target lighting apparatus, the terminal can still receive the relayed signal through the relay lighting apparatus, thereby maintaining communication reliability while preserving multi-channel adaptability

AI summary
A lighting apparatus among a plurality of lighting apparatuses in a wireless mesh network in a lighting system including the plurality of lighting apparatuses and a terminal which performs wireless communication with the lighting apparatus includes: a communication circuit which performs wireless communication; and a controller which controls the communication circuit. The controller establishes a connection with the terminal. When another lighting apparatus included in the plurality of lighting apparatuses transmits a signal (second signal) to the terminal using wireless communication, the controller receives the second signal via the communication circuit, and transmits the second signal to the terminal via the communication circuit.
