Vehicle Lighting Device with Converging Lines for Depth Perception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lighting configurations fail to effectively create a sense of depth and width in vehicle compartments, limiting the perceived space and convenience, especially when loading or unloading luggage.
Innovation Solution
A lighting device comprising multiple lighting bodies strategically placed along reducing gaps in the vehicle width direction, including a map lamp, rear seat reading lamps, rear pillar lightings, trunk lightings, and rear gate lightings, which are automatically turned on and off with the rear gate, creating a continuous illumination effect that enhances the perception of depth and unity between the interior and exterior.

Engineering Contradiction Analysis
1Shape
If multiple lighting bodies are disposed along connecting lines with gradually reducing gaps from rear to front, then a perspective sensation of depth is created in a wider region, but the device complexity increases
Solution Approach 1:
The lighting system is divided into multiple separate lighting bodies (map lamp, rear seat reading lamps, rear pillar lightings, trunk lightings, rear gate lightings) positioned at different locations. Each lighting body is independently arranged along connecting lines that converge toward the front of the vehicle, creating segmented visual cues that collectively produce a perspective sensation of depth and width throughout the vehicle interior.
Solution Approach 2:
Different lighting bodies are strategically positioned to illuminate specific local areas (map lamp for front seating area, rear seat reading lamps for rear seating, trunk lightings for luggage compartment, rear gate lightings for rear access). This local illumination strategy, combined with the converging arrangement, creates varying perceived depth in different zones while managing overall system complexity through functional distribution.

If lighting bodies are positioned to illuminate both interior and exterior when rear gate is open, then continuous illumination creates unified space perception, but energy consumption increases
Solution Approach 1:
The rear gate lightings are designed to dynamically adjust their illumination function based on the state of the rear gate. When the rear gate is closed, these lightings illuminate the interior luggage compartment. When the rear gate is opened, the same lightings automatically redirect illumination to the exterior area, creating continuous lighting that unifies the perception of interior and exterior spaces while adapting energy usage to actual operational needs.
Solution Approach 2:
The rear gate lightings serve multiple functions: illuminating the interior luggage compartment when the gate is closed, and illuminating the exterior loading area when the gate is open. This multi-functionality allows a single lighting component to address both interior and exterior illumination needs, creating unified space perception without requiring separate lighting systems for each condition, thereby managing energy consumption efficiently.

AI summary
A lighting device for a vehicle includes a map lamp, left and right rear seat reading lamps, left and right trunk lightings, left and right rear gate lightings, and left and right rear pillar lightings. The map lamp, the left rear seat reading lamp, the left trunk lighting, the left rear gate lighting, and the left rear pillar lighting are disposed along a left connecting line. In addition, the map lamp, the right rear seat reading lamp, the right trunk lighting, the right rear gate lighting, and the right rear pillar lighting are disposed along a right connecting line. The left and right connecting lines extend such that a gap in a vehicle width direction is gradually reduced from a rear side of the vehicle toward a front side of the vehicle.
