Dynamic Vehicle Headlamp Layout for Full-Width Lighting Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle headlamp systems only generate a dynamic lighting effect on a portion of the vehicle's corners, making the effect unnoticeable and less visually impactful.
Innovation Solution
A dynamic vehicle headlamp system comprising first and second headlamp modules, a grille light module, and a control module, all connected to an ECU, which coordinates the lighting of decorative light units and grille lights to create a comprehensive dynamic lighting effect across the vehicle's front side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If decorative lights are installed only in left and right headlamp devices, then the device complexity is reduced, but the area of dynamic lighting presentation is limited and the visual effect is unnoticeable
Solution Approach 1:
The lighting system is divided into multiple independent modules: left headlamp module, right headlamp module, and grille light module. Each module contains decorative light units that can be controlled independently, allowing the lighting effect to be extended across the entire front of the vehicle while maintaining modular simplicity for installation and maintenance
Solution Approach 2:
The patent combines decorative light units from both headlamp devices with additional grille light units into a unified lighting system. The control module coordinates all these light units to work together, creating a comprehensive dynamic lighting effect that spans the entire front of the vehicle, thereby expanding the visible area without significantly increasing overall system complexity
2Illumination intensity
If decorative lights are installed only in left and right headlamp devices, then the installation cost is reduced, but the visual appeal and consumer attention are insufficient
Solution Approach 1:
The lighting system extends from the traditional two-dimensional headlamp areas into the third dimension by incorporating grille light units that span the width of the vehicle's front grille. This creates a broader, more immersive lighting display that covers the entire front fascia, significantly enhancing visual appeal and making the dynamic lighting effect noticeable from a distance
3Area of stationary object
If the dynamic lighting effect is limited to corners of the vehicle head, then the system simplicity is maintained, but the lighting coverage area is insufficient
Solution Approach 1:
The control module serves multiple functions: it controls the traditional headlamp lighting, manages the decorative light units in headlamps, and coordinates the grille light units. This multi-functional controller enables comprehensive lighting coverage across the entire front of the vehicle while maintaining a single point of control, thereby simplifying the user interface and system operation despite the expanded lighting coverage

AI summary
A dynamic vehicle headlamp system is adapted to be mounted to a vehicle and be signally connected to an electronic control unit (ECU) of the vehicle. The dynamic vehicle headlamp system includes a first headlamp module, a second headlamp module, a grille light module, and a control module. The first headlamp module includes a first decorative light unit, and the second headlamp module includes a second decorative light unit. The control module is signally connected to the first headlamp module, the second headlamp module and the grille light module, and is adapted to be signally connected to the ECU. The control module is configured to be actuated by a light control signal transmitted from the ECU to control the first decorative light unit, the second decorative light unit and the grille light unit (51) to function in a predetermined lighting mode.
