Vehicle Lighting Control Architecture for Section Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles, particularly rail vehicles, existing lighting control systems face challenges in synchronizing lighting across different sections, leading to relative delays in implementing lighting scenarios due to the need for powerful data processing and multiple independent light control units.
Innovation Solution
A method and device where a central control component sends lighting data to separate driver components via a data connection, allowing these components to control lighting devices independently, enabling centralized management of lighting across the vehicle without requiring additional computing power or complex internal interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple independent light control units are provided per vehicle section, then each section can control lighting independently, but implementation delays occur across different vehicle sections
Solution Approach 1:
The system divides lighting control into two functional segments: a central control unit that generates lighting scenarios and sends control signals, and distributed light control units that execute these signals locally. This segmentation allows independent local execution while maintaining centralized coordination, eliminating implementation delays across sections.
Solution Approach 2:
The patent merges the control functions of multiple independent light control units into a single central control unit that coordinates all sections. By consolidating scenario generation and distribution while maintaining local execution capability, the system achieves synchronized lighting across all vehicle sections without the delays associated with multiple independent controllers.
2Productivity
If powerful data processing resources are provided in light control units, then lighting scenarios can be processed locally, but costs increase
Solution Approach 1:
The patent extracts the complex data processing and scenario generation functions from individual light control units and consolidates them in a central control unit. This extraction allows light control units to be simpler and less expensive, while still maintaining the ability to process lighting scenarios through centralized coordination and local execution.
3Adaptability or versatility
If multiple independent light control units are provided, then each can control its section independently, but the system complexity increases
Solution Approach 1:
The system segments control functions by separating scenario generation (central unit) from scenario execution (distributed units). This segmentation maintains adaptability for independent section control while reducing overall system complexity through centralized coordination and standardized communication protocols.

AI summary
The present invention relates to a method (100) and a device (1) for controlling the lighting in a vehicle (50), in particular a rail vehicle, as well as a lighting system (10) and a vehicle (50) with such a lighting system (10). A control component (20) sends (S3) lighting data via a data connection (60) to at least one separate driver component (30). The driver component (30) then sends (S4) a control signal based on the lighting data via a signal connection (70) to at least one light source (40).
