Vehicle Lamp Optical System Merging Multiple Pattern Images
Solution Overview
Problem
Current vehicle lamps require complex configurations and increased costs to form light irradiation patterns with multiple pattern images, as each optical system must be separately provided for each pattern image.
Innovation Solution
A vehicle lamp design that includes a light emission system and an optical system with multiple optical modules, where light beams from multiple sources are directed and reflected to form pattern images at different positions using incident and exit lenses, and shields with transmissive regions, allowing for uniform brightness and size across varying positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate optical systems are provided for each pattern image, then multiple pattern images can be formed, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges multiple optical systems into a single integrated optical system that can form multiple pattern images simultaneously. The optical system includes a light source, a first optical member (lens or reflector) that receives light from the light source, and a second optical member (prism or reflector array) that divides the light into multiple beams to form multiple pattern images on a road surface, thereby eliminating the need for separate optical systems for each pattern image.
Solution Approach 2:
The optical system is designed with multi-functionality to form various light irradiation patterns including multiple pattern images. The second optical member can be configured to divide light into multiple beams that create different pattern images (e.g., first, second, and third pattern images) depending on the lighting condition, allowing a single system to perform multiple functions that previously required separate systems.

3Volume of moving object
If micro-lenses with short focal point distance are used, then lamp size is reduced, but the ability to form required light irradiation patterns becomes limited
Solution Approach 1:
The patent introduces a second optical member (prism or reflector array) that operates in a different dimensional space to divide light into multiple beams. This allows the system to maintain a compact size using micro-lenses with short focal lengths while still achieving the capability to form multiple complex light irradiation patterns by adding the light-dividing function in another optical dimension.
