Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Provisioning LED fixtures in a wireless network for large spaces is costly and time-consuming due to the need for manual registration and assignment of unique IDs during installation.
Innovation Solution
LED fixtures modulate nonvisible light with a unique node ID, allowing a portable wireless electronic device to detect and extract this ID for automatic provisioning into a wireless network, enabling automated grouping and adjustment of lighting properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual registration and marking of each LED fixture is performed during installation, then each LED fixture can be properly associated with its location in the wireless network, but the provisioning process becomes costly and time-consuming
Solution Approach 1:
The LED fixture automatically broadcasts its unique node ID through modulated nonvisible light during installation, enabling the portable device to detect and extract the ID without manual intervention. This self-service mechanism eliminates the need for trained specialists to manually register and mark each fixture, significantly reducing provisioning time while ensuring reliable location association.
Solution Approach 2:
The patent replaces the manual mechanical process of writing IDs on fixtures with an optical communication system. The modulation circuitry modulates nonvisible light emitted by LEDs with the unique node ID, and the portable device uses light receiver circuitry to detect and demodulation circuitry to extract the ID automatically, substituting human labor with automated optical detection.
2Measurement precision
If manual registration of LED fixtures is performed by trained specialists, then accurate network provisioning is achieved, but deployment cost increases
Solution Approach 1:
The system enables automated provisioning where the portable wireless electronic device automatically detects, extracts, and provisions LED fixtures using their broadcasted unique node IDs. This eliminates the need for trained specialists, reducing deployment costs while maintaining accurate registration through automated optical detection and network provisioning processes.
Solution Approach 2:
The patent introduces a portable wireless electronic device as an intermediary between the LED fixtures and the wireless network. This device acts as a mediator that automatically detects node IDs through modulated light, extracts the information, and provisions the fixtures into the network, replacing the need for human specialists while ensuring accurate registration.
3Ease of operation
If unique IDs are assigned in written form or as QR codes, then each LED fixture can be identified, but the provisioning process requires manual intervention and marking
Solution Approach 1:
The patent replaces manual identification methods (written form or QR codes) with an automated optical communication system. The modulation circuitry modulates nonvisible light emitted by LEDs with the unique node ID, enabling automatic detection and extraction by the portable device, thereby eliminating manual intervention while maintaining unique identification capability.
Solution Approach 2:
The LED fixture autonomously broadcasts its unique node ID through modulated nonvisible light, allowing the portable device to automatically detect and extract the identification information without requiring manual reading or scanning of written forms or QR codes. This self-service approach enhances automation while preserving identification functionality.

AI summary
A method of provisioning LED fixtures in a wireless network includes: detecting nonvisible light emitted by each of the LED fixtures, using a portable wireless electronic device that comes into range of each of the LED fixtures one at a time; extracting, from the detected nonvisible light for each of the LED fixtures, a unique node ID assigned to each of the LED fixtures; and provisioning each of the LED fixtures into the wireless network, based on the unique ID extracted from the detected nonvisible light for each of the LED fixtures. Embodiments of the LED fixtures and a portable wireless electronic device used as part of the provisioning method are also described.
