Solution Overview
Problem
Identifying a specific luminaire for wireless connection is difficult, especially in environments with many luminaires, as existing methods rely on signal strength and visibility, which can lead to incorrect connections.
Innovation Solution
A luminaire equipped with a light sensor and wireless communications interface that activates upon illumination, allowing it to enter an advertising state and transmit messages for easy detection and connection by a control device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the luminaire uses wireless communication interface to enable remote control and data transfer, then the ease of operation and maintenance is improved, but the difficulty of identifying the specific luminaire for connection increases
Solution Approach 1:
The patent employs visual indicators (such as LED lights or color-coded elements) on the luminaire that change color or illuminate to indicate the wireless communication state. When the light sensor detects illumination, the luminaire displays a specific visual signal (e.g., blinking LED) to help users identify which luminaire is ready for connection, thereby resolving the difficulty of identifying the correct device among multiple luminaires.
Solution Approach 2:
The patent introduces a light sensor as an intermediary element that detects external illumination and triggers the wireless communication interface to enter advertising mode. This intermediary mechanism bridges the gap between user action (shining light) and system response (wireless connectivity), making the identification and connection process more intuitive and reliable.
2Ease of operation
If the wireless communications interface remains active by default to ensure immediate connectivity, then the ease of operation is improved, but the energy consumption increases
Solution Approach 1:
Instead of keeping the wireless communications interface continuously active, the patent implements periodic activation triggered by light sensor detection. When the light sensor detects illumination, the interface enters advertising mode for a predetermined period to allow connections. This periodic activation pattern reduces energy consumption compared to continuous operation while still providing timely connectivity when needed.
Solution Approach 2:
The system prepares for potential connectivity needs by implementing a quick activation mechanism. When illumination is detected, the wireless interface rapidly transitions to advertising state, providing preliminary readiness for connection. This approach balances immediate responsiveness with energy efficiency by only activating when preliminarily needed rather than maintaining constant readiness.
