Solution Overview

Problem

Traditional lighting control systems rely on preprogrammed logic that cannot optimally adapt to the specific characteristics of a space, leading to suboptimal lighting performance and energy consumption, and manual mapping of luminaires in complex environments is tedious and prone to errors.

Innovation Solution

A method and apparatus for classifying luminaires based on sensor data, including environmental characteristics like CO2, VOC, humidity, and air pressure, to assign them to predefined classes and adjust lighting control parameters, facilitating automatic or semi-automatic grouping and fine-tuning of lighting systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If preprogrammed lighting control logic is used, then general applicability is ensured, but optimized lighting performance for specific spaces cannot be achieved

Engineering Contradiction:
Improvegeneral applicabilityVSAvoidlighting performance optimization
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system continuously collects sensor data (occupancy, light levels, environmental conditions) and uses this feedback to dynamically adjust lighting control parameters. The control entity analyzes sensor signals in real-time and modifies lighting output accordingly, enabling the system to adapt to specific space characteristics while maintaining general applicability through automated learning and optimization.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If manual mapping of luminaires is performed, then accurate luminaire-position mapping is achieved, but the process is tedious and error-prone

Engineering Contradiction:
Improveluminaire mapping accuracyVSAvoidmapping time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system automatically performs luminaire mapping by having each luminaire transmit its identifier and position information to the control entity. The control entity collects this data from multiple luminaires, processes the information to create a spatial map, and stores it in a database without requiring manual intervention. This self-service approach achieves accurate mapping while eliminating the tedious manual process.

Inventive Principle:
Principle #25Self-service

3Ease of manufacture

If preprogrammed control parameters are used, then ease of installation is improved, but energy consumption optimization is compromised

Engineering Contradiction:
Improveease of installationVSAvoidenergy consumption
Core Design Contradiction:
Ease of manufactureVSLoss of energy

Solution Approach 1:

The system transitions from static preprogrammed parameters to dynamic, real-time adjusted parameters. The control entity continuously monitors sensor data (occupancy status, light levels, environmental conditions) and dynamically modifies lighting parameters such as intensity, color temperature, and timing. This dynamic adjustment optimizes energy consumption by adapting lighting output to actual space conditions while maintaining ease of installation through automated parameter tuning.

Inventive Principle:
Principle #15Dynamics
