Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light source devices face challenges in precisely adjusting the position and size of the light collection spot, leading to degraded light quality due to the complex configuration of optical members and difficulty in independent adjustment.
Innovation Solution
A light source device configuration that includes a light source unit emitting substantially parallel light, a concave mirror, and a convex mirror, where the light is sequentially reflected by these mirrors to guide it towards a light collection spot, allowing for independent adjustment of the spot's position and size through three-axis movement of the convex mirror.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the arrangement positions of optical members are changed to adjust the light collection spot, then the position of the light collection spot can be adjusted, but both the position and size of the light collection spot change simultaneously making independent adjustment difficult
Solution Approach 1:
The patent introduces a convex mirror as a separate optical member that can be independently adjusted from the concave mirror and light source. This segmentation allows the light collection spot position and size to be adjusted independently by moving the convex mirror in different directions, resolving the coupling problem where changing one parameter affects the other.
Solution Approach 2:
The patent implements adjustable optical members (concave mirror and convex mirror) that can be dynamically repositioned during assembly or operation. This dynamic adjustment capability allows for precise control of the light collection spot characteristics without being constrained by fixed optical paths.
2Reliability
If multiple optical members are used to guide light, then light can be effectively collected and guided, but the configuration becomes complex making precise adjustment difficult
Solution Approach 1:
The optical system is divided into distinct functional segments: a light source unit, a concave mirror for light collection, and a convex mirror for light direction control. Each segment has a specific function and can be independently optimized and adjusted, simplifying the overall adjustment process while maintaining high light collection efficiency.
Solution Approach 2:
The patent uses a convex mirror to add a new dimension of control to the optical system. By positioning and adjusting the convex mirror in three-dimensional space, the system gains additional degrees of freedom for controlling light direction and focus without requiring complex multi-element optical assemblies.
