Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle headlight lighting devices face challenges in generating a desired light image due to manufacturing inaccuracies and imprecise positioning of optical components, leading to deviations from the intended light distribution.
Innovation Solution
The lighting device allows for adjustable positioning of the optical component relative to the light conversion element through a mounting module with guide means and adjusting screws, enabling independent linear movements in two directions to compensate for inaccuracies and achieve precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the optical component is permanently connected to the lighting module, then the structure is simple and robust, but manufacturing inaccuracies and positioning errors lead to deviations from the desired light image
Solution Approach 1:
The mounting module enables dynamic adjustment of the optical component's position relative to the lighting module through guide means and adjusting screws, allowing the system to adapt to manufacturing inaccuracies while maintaining structural connection
Solution Approach 2:
The mounting module is divided into separate functional elements: guide means for constrained movement and adjusting screws for precise positioning, allowing independent optimization of each component's function
2Manufacturing precision
If the optical component is made adjustable to compensate for positioning errors, then the light image accuracy is improved, but the device complexity increases
Solution Approach 1:
Adjustability is provided only where needed at the interface between the lighting module and optical component, while the rest of the system maintains simple permanent connections, minimizing overall complexity
Solution Approach 2:
The mounting module acts as an intermediary element between the lighting module and optical component, providing adjustment functionality without requiring changes to the main system architecture

AI summary
The invention relates to a lighting device (1) for a motor vehicle headlight, having at least one lighting module (2) for emitting visible light, at least one optical component (3) which deflects and/or shapes the light of the lighting module (2), and a mounting module (4) which is connected to the lighting module (2) and in which the at least one optical component (3) is supported. The lighting module (2) comprises at least one laser light source (2a) and a light conversion element (2b). The light of the at least one laser light source (2a) is deflected onto the light conversion element (2b) which converts the light into visible light and emits the visible light into the optical component (3). The mounting module (4) has at least one first and a second guide means (4b', 4h), and the optical component (3) can be moved with respect to the light conversion element (2b) in a first direction (x) by means of the first guide means (4b') and in a second direction (z) by means of the second guide means (4h), wherein the first and the second direction (x, z) differ from one another.
