Ring Flash Light Diffuser for Softening Harsh Shadows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Photographers face challenges in capturing images with inadequate light environments, particularly when needing to move freely or photographing subjects close to the camera, as existing light diffusion methods are cumbersome and inadequate for creating soft, diffuse lighting.
Innovation Solution
A portable ring flash light diffusion device that attaches to the camera lens, featuring a semitransparent light diffuser connected via a series of converter rings and adapters, allowing for easy installation and adjustment with various ring flash types and lens sizes, providing a softer lighting effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a ring flash is positioned close to the camera lens for portability and freedom of movement, then ease of operation and adaptability are improved, but the light becomes sharp and bright creating dark deep shadows with high contrast
Solution Approach 1:
A light diffuser is introduced as an intermediary component between the ring flash and the subject. The diffuser is a translucent or transparent element that scatters the light from the ring flash, transforming the sharp bright light into soft diffuse light, thereby eliminating the harmful effect of dark deep shadows while maintaining the portability benefit of having the light source close to the camera
Solution Approach 2:
The optical parameters of the light are changed by passing it through a diffuser material. The diffuser alters the light's directionality and intensity distribution, converting concentrated directional light into dispersed omnidirectional light, thereby changing the lighting quality from harsh to soft without changing the position of the ring flash
2Object-affected harmful factors
If traditional diffusion methods use large light sources far from the subject or multiple reflective surfaces, then light diffusion quality is improved, but device complexity and portability are worsened
Solution Approach 1:
The patent combines the ring flash, light diffuser, and mounting components into a single integrated portable device that attaches to the camera lens. This merging of components achieves effective light diffusion (normally requiring large separate structures) in a compact form factor, eliminating the need for multiple reflective surfaces or large distant light sources while maintaining soft lighting quality
Solution Approach 2:
The light diffuser is positioned within or around the ring flash structure, with components nested together in a compact arrangement. The diffuser element is integrated into the ring flash assembly, allowing the entire system to be mounted on the camera lens like a single unit, thereby achieving complex diffusion functionality in a simplified portable package
3Object-affected harmful factors
If a light diffuser is added to the ring flash system, then light diffusion quality is improved, but the device becomes more complex and harder to install
Solution Approach 1:
The mounting system is designed with universal compatibility features, using standard camera lens thread sizes and common ring flash mounting interfaces. This allows the same diffuser device to be installed on various camera and ring flash combinations without requiring custom adapters, thereby reducing installation complexity while maintaining effective light diffusion across different configurations

AI summary
A ring flash light diffusion device includes a first converter ring configured to connect to a camera lens and a diffuser adapter. The diffuser adapter can be connected to a first end of the first converter ring. It also includes a flash ring connected to the diffuser adapter at a position along the length of the diffuser adapter and a ring flash connected to the flash ring. It further includes a light diffuser connected to the diffuser adapter such that light emitted from the ring flash passes through the light diffuser.
