Solution Overview
Problem
Conventional lighting systems require significant effort for communication setting between wireless communication devices and luminaires immediately after installation, especially in large installations like gymnasiums, where overlapping infrared reception areas cause interference and prevent proper setting.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If infrared communication setting is performed in dense luminaire installations, then communication setting can be achieved, but interference from adjacent devices prevents proper setting
Solution Approach 1:
The system segments the infrared communication process by introducing a two-stage mechanism: first establishing wired connection for device identification, then enabling infrared communication only for identified devices. This segmentation isolates the infrared communication to specific time windows and device pairs, eliminating interference from adjacent devices.
Solution Approach 2:
The management device performs preliminary identification of wireless communication devices through wired connection before enabling infrared communication. This preliminary action ensures that only authorized and identified devices can receive infrared signals, preventing interference and unauthorized access in dense installations.
2Productivity
If communication setting is performed immediately after luminaire installation, then system deployment is accelerated, but significant effort and complexity are required
Solution Approach 1:
The system enables self-service communication setting where the management device automatically identifies wireless communication devices through wired connection and facilitates the infrared pairing process. This automation reduces manual configuration effort and complexity while maintaining rapid deployment capability.
Solution Approach 2:
The management device acts as an intermediary between wired network infrastructure and infrared communication. It receives wired connection information, processes device identification, and mediates the infrared communication setting process, thereby simplifying the overall system complexity while enabling rapid installation.
3Adaptability or versatility
If wired communication circuit receives operation signal from management device, then control functionality is enabled, but device transitions to specific reception state requiring coordination
Solution Approach 1:
The wireless communication device provides feedback to the management device about its reception state. When the device transitions to infrared reception state after wired connection, it notifies the management device, which then coordinates the infrared communication timing. This feedback mechanism manages state transition complexity through coordinated control.

AI summary
A wireless communication device includes: a wired communication circuit which receives, through a wired connection, an operation signal for controlling each of luminaires from a management device which controls an operation of each of the luminaires; a radio communication circuit which converts the operation signal received by the wired communication circuit and transmits the converted operation signal to each of the luminaires over a radio wave; an infrared ray receiver which receives an infrared ray signal transmitted from outside; and a controller. When the wired communication circuit receives a signal having a predetermined pattern from the management device, the controller transitions to a state for receiving the infrared ray signal, and, based on the infrared ray signal transmitted from outside, transmits a signal relating to communication setting between the radio communication circuit and each of the luminaires to each of the plurality of luminaires via the radio communication circuit.
