Segmented Vehicle Light Fixture for Compact Multi-Lamp Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle light fixtures are not compact and lightweight, as they require separate structures for multiple functional lamps.
Innovation Solution
A vehicle light fixture with a light emitting layer partitioned into segments, using organic electroluminescence material, and a control unit to manage light emission states, including brightness and timing, allowing for a single light source to function as multiple lamps by selectively illuminating segments along the rear window's periphery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of stationary object
If multiple functional lamps are integrated into a single light fixture, then the light fixture becomes compact and lightweight, but the structural complexity increases
Solution Approach 1:
The patent implements multi-functionality by using a single light emitting layer that can be selectively activated in different segments to perform multiple lamp functions (tail lamp, stop lamp, turn lamp) simultaneously, eliminating the need for separate physical lamp structures for each function
Solution Approach 2:
The light emitting layer is divided into multiple independently controllable segments that can be selectively activated, allowing a single unified structure to replace multiple separate lamp assemblies while maintaining functional independence of each lamp type
2Quantity of substance
If a single light source is used for multiple functions, then the number of components is reduced, but the control complexity increases
Solution Approach 1:
The patent applies dynamics by implementing dynamic control of the light emitting segments through a control unit that can selectively activate different segments based on required lamp functions, allowing a single static physical structure to dynamically assume multiple functional configurations
Solution Approach 2:
The control unit provides universal control capability for multiple lamp functions through a single control interface, managing the selective activation of light emitting segments to achieve tail lamp, stop lamp, and turn lamp functions without requiring separate control systems for each lamp type

AI summary
A vehicle light fixture includes: one light source including a light emitting layer partitioned into a plurality of segments capable of emitting light individually; and a control unit for causing the light emitting layer to emit light in a different light emitting state by performing control of selecting the segment for emitting light from among the plurality of segments, and control of at least one of brightness and a light emission timing of the selected segment.
