Deformable Flash Lens Control for Variable Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flash modules fail to adjust illumination based on changes in object distance or field of view, leading to inadequate lighting for varying photography conditions.
Innovation Solution
An adjustable flash module with a deformable optical lens and actuator that allows the lens to deform in various ways, such as extension, contraction, bending, and twisting, to adjust illumination patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional flash module with fixed illumination is used, then the structure is simple, but the illumination cannot be adjusted for different object distances or field of view
Solution Approach 1:
The flash module employs a deformable optical lens that can dynamically change its shape (convex, concave, or flat) in response to different object distances and field of view requirements. This dynamic adaptability allows the same flash module to provide optimized illumination for various shooting scenarios without requiring multiple fixed-illumination modules, thereby resolving the contradiction between adaptability and device complexity.
2Use of energy by moving object
If the flash module provides focused lighting for distant objects, then illumination efficiency improves, but the field of view coverage decreases
Solution Approach 1:
The optical lens in the flash module changes its optical parameters (focusing capability) by deforming into different shapes. When a convex shape is formed, the lens provides focused lighting for distant objects, improving illumination efficiency. When a flat or concave shape is formed, the lens provides diffused lighting with wider field of view coverage. This parameter change capability allows the system to optimize illumination efficiency for different shooting conditions without permanently sacrificing field of view coverage.
