Dual-mode Luminaire Controller with DALI and 0-10V Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Luminaire controllers are limited to either analogue ('0-10V') or digital (DALI) control systems, requiring specific configuration to match the luminaire and interface receptacle, leading to miswiring and polarity issues.
Innovation Solution
A luminaire controller with a central processing module and isolated supply featuring both DALI and '0-10V' interfaces, allowing adaptable dimming signal provision based on the luminaire's protocol, along with a communications module for remote interface selection and a service link for override and updates, including energy metering and ambient condition sensing.

Engineering Contradiction Analysis
1Reliability
If luminaire controllers are configured for specific control systems (analogue or digital), then the control precision and reliability are improved, but the adaptability to different luminaire types deteriorates
Solution Approach 1:
The luminaire controller is designed with dual capability to support both analogue (0-10V) and digital (DALI) control protocols through a single device. The controller includes both an analogue control interface and a digital control interface, allowing it to adapt to different luminaire types without requiring separate specialized controllers for each protocol type.
2Reliability
If separate controllers are provided for different control systems, then the control precision for each system is improved, but the device complexity increases
Solution Approach 1:
The patent combines both analogue (0-10V) and digital (DALI) control interfaces within a single luminaire controller device. This merging eliminates the need for separate specialized controllers for different control systems, reducing overall system complexity while maintaining the precision benefits of both control types through a unified device architecture.
3Reliability
If interface receptacles are configured for specific protocols, then the miswiring prevention is improved, but the ease of operation deteriorates
Solution Approach 1:
The luminaire controller automatically detects and adapts to the appropriate control protocol (analogue or digital) based on the connected luminaire type. This self-service capability eliminates the need for manual configuration or complex installation procedures, allowing installers to connect the controller to any luminaire type without requiring specialized knowledge of different protocols or performing complex wiring configurations.
