Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light module control systems lack the ability to separate control functions from power functions, limiting the number of control options available, especially when using classical dimmers.
Innovation Solution
An apparatus comprising a first circuit for detecting control information from a combined power and control signal, and a second circuit for converting this information into a separate control signal, allowing for enhanced control options by separating control from power functions, with additional features like galvanic isolation and signal filtering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If control information is transported via a combined power and control signal (first signal), then the system can work with classical dimmers and existing infrastructure, but the control function cannot be separated from the power function, limiting control options
Solution Approach 1:
The patent segments the combined first signal into separate power and control components. The first circuit extracts control information from the combined signal, and the second circuit converts it to a separate control signal (second signal). This segmentation enables independent control and power delivery, resolving the contradiction between versatility and complexity.
Solution Approach 2:
The patent introduces intermediary circuits (first circuit for detecting control information, second circuit for converting it) that mediate between the combined power/control signal and the separate control signal. These intermediaries enable the separation of control functions while maintaining compatibility with existing classical dimmer infrastructure.
2Adaptability or versatility
If control information is extracted and converted through separate circuits, then control can be separated from power functions for enhanced flexibility, but the device complexity increases
Solution Approach 1:
The apparatus is designed with multi-functionality to handle various control information types (phase-cut dimming, digital data, modulated signals) through the same circuit architecture. The first and second circuits can process different input formats and produce versatile control outputs, achieving high adaptability without proportionally increasing complexity.
Solution Approach 2:
The second circuit converts control information by changing parameters (amplitude, timing, pulse-width, pulse-height, or data format) to create the second control signal. This parameter transformation approach provides flexible control adaptation while using standard circuit techniques, balancing versatility with manageable complexity.

AI summary
Apparatuses for controlling light modules (5) comprise first circuits (1) for detecting first control information transported via first signals and second circuits (2) for converting first control information into second control information. The second control information is transported via second signals. The first and second control information define light settings of the light modules (5) and have different representations. The first control information may be phase-cut information or first data. The second control information may be a parameter of the second signal or second data. The apparatus may further comprise a third circuit (3) for converting power from the first signals into third signals destined for power inputs (51) of the light modules (5). The second signals may be destined for control inputs (52) of the light modules (5). This way, a control of a light module (5) has been separated from powering the light module (5). Many more control options have become possible.
