Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Implementing specific light characteristics in illumination systems is challenging due to manufacturing tolerances in modern solid-state luminaires and the dependency of light characteristics on control gear, leading to time-consuming and error-prone manual calibration.
Innovation Solution
A method that searches an electronic database for a combination of control gear and luminaires to determine an optimal electrical operating point, allowing for automatic configuration and reducing the need for manual calibration by creating an electronic configuration file for the selected control gear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual calibration of control gear operating point is performed to achieve desired light characteristics, then light characteristic precision is improved, but installation time and cost increase
Solution Approach 1:
The patent applies preliminary action by pre-measuring and storing the light characteristics of individual luminaires in a database during manufacturing, before installation. This allows the system to automatically retrieve and use pre-determined operating points from the database, eliminating the need for manual calibration during installation while maintaining precise light characteristics.
2Manufacturing precision
If manual calibration of control gear operating point is performed to achieve desired light characteristics, then light characteristic precision is improved, but error risk increases
Solution Approach 1:
The patent implements feedback by using pre-measured actual light characteristics of each luminaire (obtained during manufacturing) to automatically determine the optimal operating point of the control gear. This closed-loop approach ensures that the system automatically compensates for manufacturing tolerances and achieves consistent, reproducible light characteristics without manual intervention.
3Measurement precision
If individual luminaire calibration is performed to account for manufacturing tolerances, then light characteristic accuracy is improved, but system complexity increases
Solution Approach 1:
The patent applies copying by creating digital replicas of each luminaire's light characteristics during manufacturing and storing them in a database. These digital copies contain all necessary information about the luminaire's optical properties, allowing the control system to automatically retrieve and use this data without requiring physical measurement or calibration equipment during installation.
