Vehicle Lamp Image Display with Light Guide Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a vehicle lamp that can efficiently display various functions while minimizing the space required for installation, as electric vehicles require multiple lamps for illumination and signaling purposes, including indicating the charging state of the battery, which can be cumbersome when each lamp is separately installed.
Innovation Solution
A vehicle lamp with multiple image forming units, each comprising a light source and a light guide, where light is transmitted through the guides to form images suitable for different functions, allowing for reduced space usage by combining the functions of multiple lamps into a single unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate lamps are installed for different functions (illumination, signaling, charging state indication), then each lamp function can be sufficiently achieved, but the space required for installation increases
Solution Approach 1:
The patent combines multiple separate lamp functions (illumination, signaling, charging state indication) into a single integrated vehicle lamp unit. This merging approach allows the vehicle to achieve all necessary lamp functions while occupying reduced installation space, directly resolving the technical contradiction between functional completeness and space efficiency
Solution Approach 2:
The vehicle lamp is designed as a multi-functional device that simultaneously performs illumination, signaling, and charging state indication functions. This universal design enables a single lamp unit to replace multiple separate lamps, achieving the same functional reliability with reduced installation area
2Reliability
If multiple separate lamps are installed for different functions, then each function can be sufficiently achieved, but the device complexity increases
Solution Approach 1:
The patent merges multiple separate lamp systems into a single integrated unit, reducing the overall device complexity. By combining illumination sources, light guides, and control systems into one modular assembly, the patent simplifies the vehicle's lamp configuration while maintaining all necessary functions
Solution Approach 2:
The multi-functional lamp design reduces device complexity by eliminating the need for multiple separate lamp assemblies. A single universal lamp unit performs all required functions, reducing the complexity of installation, wiring, and system management compared to multiple separate lamps

AI summary
Provided is to a vehicle lamp capable of displaying images with various colors or shapes. The vehicle lamp includes an image display for displaying an image formed by a plurality of image forming units, each of the plurality of image forming units including a light source unit and a light guide for emitting light incident from the light source unit; and a controller configured to generate an image at least one of the plurality of image forming units. In particular, the plurality of image forming units comprises a first image forming unit comprising a first light source unit and a first light guide; and a second image forming unit comprising a second light source unit and a second light guide. The light emitted from the first light guide is transmitted through the second light guide and emitted.
