Decoupled Laser Headlight Module for Adaptive Beam Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle headlights lack adaptive light functions, as laser light modules are typically rigidly coupled to main light modules, limiting their ability to adjust light distribution based on driving conditions or to avoid dazzling other road users.
Innovation Solution
A headlight design that decouples the laser light distribution from the main light distribution, allowing it to be moved and pivoted independently using an actuator system or micro-optical components, enabling adaptive light functions and improved illumination of specific regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the laser light module is rigidly coupled to the main light module, then the structure is simple and stable, but the laser light distribution cannot be adjusted independently to adapt to different driving conditions
Solution Approach 1:
The headlight system is divided into independent modules: main light modules for producing main light distribution and a separate laser light module for producing laser light distribution. This segmentation allows each module to function independently while contributing to the overall lighting system, enabling adaptive light functions without requiring the entire system to be complex.
Solution Approach 2:
The laser light module is made movable and pivotable relative to the main light modules through an actuator system. This dynamic capability allows the laser light distribution to be adjusted independently to different positions and angles, enabling adaptation to various driving conditions such as cornering lights, high beam assistance, and avoiding dazzling other road users.
2Adaptability or versatility
If the laser light module is decoupled and made movable, then adaptive light functions are enabled, but the device complexity and installation size increase
Solution Approach 1:
The laser light module is integrated within the overall headlight assembly structure, nesting the movable component within the existing housing. This allows the decoupled laser module to be accommodated without significantly increasing the external dimensions of the headlight, maintaining a compact installation size while enabling adaptive functions.
Solution Approach 2:
The actuator system enables the laser light module to achieve multiple positions and orientations within a limited space range. By designing the movement mechanism to operate within compact dimensions, the system provides full adaptive functionality without requiring excessive installation volume.
3Illumination intensity
If the laser light distribution is fixed relative to main light distribution, then manufacturing is simpler, but the ability to illuminate specific regions with greater intensity is limited
Solution Approach 1:
The lighting system separates main light production and laser light production into distinct modules, allowing each to be manufactured and tested independently. The laser light module can be precisely positioned and aligned during assembly to achieve optimal illumination intensity in specific regions without complicating the overall manufacturing process.
Solution Approach 2:
The movable laser light module can be positioned at different angles and distances relative to the main light modules during assembly and operation. This dynamic positioning capability allows the system to illuminate specific regions with greater intensity by adjusting the laser beam direction, while the modular design keeps manufacturing straightforward.
