Solution Overview

Problem

The high number of wireless nodes in connected TLED systems results in a labor-intensive commissioning process, requiring skilled technicians to identify and join each lamp individually to a control network, which is inefficient and time-consuming.

Innovation Solution

A method where each luminaire includes a constrained signalling medium, such as a power supply circuit, allowing lamps to detect and identify other lamps within the same luminaire through signal modulation, enabling automatic grouping and commissioning as a single unit, reducing the need for individual lamp commissioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If each lamp is equipped with an individual wireless interface for remote control, then lighting control functionality is improved, but the commissioning process complexity increases due to the high number of wireless nodes

Engineering Contradiction:
Improvelighting control functionalityVSAvoidcommissioning process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple lamps within the same luminaire into a single commissioning unit by utilizing the constrained signalling medium (power supply circuit). Lamps communicate with each other through this shared medium, allowing them to automatically form groups and be commissioned collectively rather than individually, thus reducing commissioning complexity while maintaining individual wireless control capability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces the constrained signalling medium (power supply circuit) as an intermediary communication channel between lamps. This intermediary enables automatic identification and grouping of lamps within the same luminaire, allowing commissioning tools to interact with groups rather than individual nodes, thereby simplifying the commissioning process

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If skilled technicians perform individual lamp commissioning to ensure reliable network integration, then network integration reliability is improved, but the loss of time and productivity decrease due to labor-intensive processes

Engineering Contradiction:
Improvenetwork integration reliabilityVSAvoidcommissioning speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent enables lamps to perform self-service by automatically detecting and identifying other lamps through the constrained signalling medium. Lamps autonomously form groups and establish network connections without requiring manual intervention for each device, thereby maintaining reliable network integration while dramatically increasing commissioning speed and productivity

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent implements preliminary grouping action where lamps automatically form logical groups based on their physical location in the same luminaire before actual network commissioning. This preliminary organization ensures reliable network integration while reducing the time required for the commissioning process, as groups are pre-established rather than configured individually

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If individual lamp identification methods are used during commissioning, then measurement precision of lamp location is improved, but the device complexity and time required for commissioning increase

Engineering Contradiction:
Improvelamp location identification accuracyVSAvoidcommissioning time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent makes the constrained signalling medium (power supply circuit) serve multiple functions: it simultaneously provides electrical power to the lamps and acts as a communication channel for identification and grouping. This multi-functionality enables precise location identification without requiring separate identification hardware or increasing commissioning time, as the same existing infrastructure is utilized for both purposes

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A first lamp for use in a luminaire, the first lamp comprising: a transmitting circuit configured to transmit, and/or a receiving circuit configured to receive, one or more signals via a constrained signalling channel whereby propagation of the signals is constrained by a physical characteristic of the luminaire; and a controller configured to detect, based on the transmission and/or reception of these one or more signals via the constrained signalling channel, that one or more other, second components (e.g. other lamps) are present in the same luminaire as the first lamp, and to identify the one or more second components based on the transmission and/or reception of the one or more signals.
