Integrated Controller Synchronizes Vehicle Light Intensity Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lighting control systems often result in uncoordinated light-intensity switching operations, leading to a strange or low-quality impression for drivers and passengers, as multiple lamps are controlled independently or in a linked manner without ensuring synchronized transitions.
Innovation Solution
A lighting control system with multiple light sources and drivers, controlled by an integrated controller that adjusts light emission intensity in at least two levels, ensuring that the timing of light intensity transitions ends simultaneously across all sources, providing a unified and coordinated lighting experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple lamps are controlled independently or in a linked manner without synchronized transitions, then each lamp can be controlled individually, but the light-intensity switching operations appear uncoordinated to drivers and passengers
Solution Approach 1:
The patent combines multiple individual lamp control operations into a unified coordinated control system. The control unit synchronizes the light intensity transitions of multiple lamps so that they change intensity simultaneously or in a predetermined sequence, merging independent control actions into a harmonized lighting operation that eliminates uncoordinated switching perceptions.
2Reliability
If light intensity transitions are synchronized across all light sources, then a unified and coordinated lighting experience is achieved, but the control system complexity increases
Solution Approach 1:
The control unit is designed as a universal multi-functional device that can simultaneously manage multiple light sources with different characteristics. It implements synchronized intensity transitions across various lamp types (LEDs, halogen lamps, etc.) by providing standardized control signals that adapt to each light source's requirements, achieving coordinated lighting without requiring separate complex control systems for each lamp.
3Use of energy by moving object
If duty cycle control is used to adjust light intensity, then energy consumption is reduced, but the light intensity transitions may not be synchronized across different light sources
Solution Approach 1:
The control unit employs feedback mechanisms to monitor the actual light intensity output of each light source and adjusts the duty cycle signals accordingly. By continuously comparing the desired intensity transition with the actual response of each light source and making real-time adjustments, the system achieves precise synchronized transitions while maintaining energy-efficient duty cycle control.

AI summary
A lighting control system includes a plurality of light sources, a plurality of light source drivers, each of the light source drivers being configured to adjust a light emission intensity of an associated one of the light sources in at least two levels, and an integrated controller configured to control the light source drivers to control conditions of the light sources in an integrated manner. The integrated controller is configured to control the light source drivers to execute a light intensity transition of reducing the light emission intensity from a first light intensity level to a second light intensity level that is lower than the first light intensity level with respect to each of the light sources such that a timing at which the light intensity transition ends is substantially the same for each of the light sources.
