Solution Overview

Problem

The time-consuming process of equipping and grouping lamps, particularly in large spaces like rooms or halls, and assigning them to operating units for efficient lighting control is inefficient, as existing methods require manual input and alignment of sensors for communication.

Innovation Solution

A method where a control device transmits switch-on signals to lamps, which measure light and respond with intensity values, allowing for automatic grouping and assignment based on distance and identification, using sensors to determine relative positions and topology, and enabling communication through power line, wireless, or light modulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual input and alignment methods are used for grouping lamps and assigning them to operating units, then identification and assignment can be achieved, but the process becomes time-consuming and inefficient

Engineering Contradiction:
Improvegrouping and assignment efficiencyVSAvoidtime for equipping and grouping lamps
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The lamp system performs automatic identification and grouping through self-service mechanisms. Each lamp autonomously responds to query signals with its identification, and the control device automatically determines spatial relationships based on light intensity measurements, eliminating the need for manual identification input and grouping assignment

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system utilizes changes in light intensity parameters to determine spatial relationships between lamps. By measuring the intensity of light received from other lamps, the system automatically infers distance and grouping information, transforming physical spatial parameters into actionable grouping data without manual intervention

Inventive Principle:
Principle #35Parameter changes

2Reliability

If sensors are aligned for communication between lamps, then data exchange can occur, but the alignment process adds complexity and time to the setup

Engineering Contradiction:
Improvecommunication between lampsVSAvoidsensor alignment requirements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system replaces mechanical alignment procedures with optical measurement-based automatic grouping. Instead of physically aligning sensors through manual adjustment, the control device queries lamps and automatically determines spatial relationships based on light intensity measurements, substituting mechanical alignment complexity with automated optical parameter analysis

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Speed

If all lamps respond simultaneously to grouping signals, then identification data can be collected quickly, but overlapping responses create communication conflicts

Engineering Contradiction:
Improveresponse speedVSAvoidresponse serialization
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The system implements periodic action through time-structured communication protocols. Lamps respond to grouping signals in sequential time slots rather than simultaneously, with each lamp transmitting its identification in a predetermined sequence. This periodic response structure eliminates overlapping communications while maintaining efficient data collection speed

Inventive Principle:
Principle #19Periodic action

AI summary

The invention relates to a method and a device for grouping at least three lamps (1) and for assigning the lamps (1) to at least one operating unit. It is time-intensive to equip one or a plurality of rooms or halls within a building with lamps (1), particularly a grouping of lamps (1), and assigning lamps (1) to at least one operating unit. Therefore, grouping of lamps (1) and assigning the lamps (1) to at least one operating unit should be simplified. In accordance with the invention, a lamp (1) emits light and the other lamps (1) measure light, and distances between the lamps (1) are determined in dependence upon at least one light value and the lamps (1) are assigned to at least one operating unit in dependence upon the distances.
