Vehicle Light Lens Array for Shaped Beam Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle light devices produce monotonous circular light spots, lacking the ability to project complex patterns such as letters or geometric shapes for low and high beam illumination.
Innovation Solution
The light device incorporates a first light emitting unit with a first lens module and a first light emitting module, where the first lens bodies are arranged to form a predetermined shape, allowing the light to project through the first lens portions and produce a specific beam illumination pattern.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a conventional bulb-shaped light emitting unit is used, then the light device is simple in structure, but the light spot is monotonous circular shape without complex patterns
Solution Approach 1:
The light emitting unit is segmented into multiple light sources arranged in specific patterns, with each light source having its own lens. This segmentation allows different light sources to form different parts of the light spot pattern, enabling complex shapes while maintaining structural simplicity through modular design
Solution Approach 2:
Different regions of the light emitting unit are assigned different functions - some light sources are equipped with lenses while others may have different optical elements or no elements. This local differentiation allows the system to create complex light spot patterns by controlling which regions emit light and in what directions
2Adaptability or versatility
If multiple light sources with lenses are arranged to form complex patterns, then the light spot can present predetermined shapes, but the device complexity increases
Solution Approach 1:
The lens module is designed with multiple light sources that can be selectively activated or deactivated. By controlling which light sources are on, the same physical structure can produce different beam illumination patterns (low beam, high beam, fog light patterns), making the device versatile without requiring multiple separate optical systems
Solution Approach 2:
The light device incorporates dynamic control capabilities where the illumination patterns can be changed by activating different combinations of light sources. This dynamic switching allows the system to adapt to different driving conditions and present various beam patterns using the same physical lens structure

Function Achieved in This Case
This configuration enables the light device to project predetermined shapes, such as letters or geometric patterns, effectively enhancing the visual appeal and functionality of the vehicle's lighting system.
Implementation Method 1
Each of the first lens bodies has a first light condensing section for condensing light forwardly from a corresponding one of the first light sources, and a first lens section which permits the condensed light to project forwardly therethrough
