Adjustable Fill Light With Independent Lighting And Device Holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fill lighting kits for mobile devices are inflexible, unstable, and inadequate for varying shooting distances and light intensities, often causing distortion or insufficient lighting in photographs and videos, especially in live broadcasting and selfie scenarios.
Innovation Solution
A fill light system with an adjustable lighting assembly, supporting assembly, and device holder that allows for independent adjustment of illumination angles and light intensity, featuring a telescoping design, multiple lighting modes, and a remote control unit to optimize lighting for different shooting conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the mobile phone is fixedly installed with the fill lighting kit at the same side, then the structure is simple, but the shooting direction of the camera is limited and cannot be adjusted independently from the light emitting direction
Solution Approach 1:
The device is divided into independent functional modules: the fill lighting kit and the mobile phone bracket are separate components that can be adjusted independently. The lighting assembly can be positioned at different locations (front, side, back) relative to the mobile phone, allowing independent adjustment of light direction and shooting direction without being fixed at the same side.
2Device complexity
If the mobile phone is supported at the middle position of the fill lighting kit, then the structure is compact, but the center of gravity becomes unstable and the device is difficult to adapt to different occasions
Solution Approach 1:
The support position is made adjustable rather than fixed. The mobile phone bracket can be positioned at different locations along the fill lighting kit (front end, middle position, or rear end), allowing the user to dynamically adjust the center of gravity based on different usage scenarios to achieve stable balance.
3Length of stationary object
If the light intensity is increased to compensate for long distance shooting, then the lighting range is extended, but the light may be too strong for close distance shooting causing image distortion
Solution Approach 1:
The light intensity parameter is made adjustable with multiple lighting modes (strong, medium, weak). Users can select appropriate light intensity based on shooting distance: stronger light for long distance shots and weaker light for close distance shots, preventing image distortion while extending lighting range.
4Ease of operation
If the lamp head rotates to adjust shooting angles, then the lighting direction changes, but the mobile phone rotates with the lamp head limiting the adjustable angle range
Solution Approach 1:
The lighting assembly and mobile phone bracket are independent adjustable components. The lamp head can rotate to adjust lighting direction, while the mobile phone bracket can independently adjust the shooting angle. This segmentation allows both lighting direction and shooting angle to be optimized separately without being coupled together.
5Illumination intensity
If the fill lighting kit is used for live broadcasting or video shooting, then supplemental lighting is provided, but the light may directly enter the subject's eyes causing discomfort or eye burning
Solution Approach 1:
The fill lighting kit provides localized supplemental lighting that can be positioned at optimal angles relative to the subject. By adjusting the lighting direction and intensity locally rather than using omnidirectional lighting, the system provides necessary illumination while minimizing direct light entry into the subject's eyes, reducing discomfort and eye burning.

AI summary
A fill light includes a lighting assembly, a supporting assembly and a device holder that is capable of being supported by the supporting assembly, wherein the lighting assembly includes a lighting body, a retainer and a base, wherein the lighting body is pivotally coupled to the retainer, wherein the retainer is adjustably arranged on the base, wherein the base retains and supports the retainer on the supporting assembly, wherein the retainer supports the lighting body, so as to allow the lighting body to form a fill lighting area by illumination of the lighting body, wherein when a photographing device is held by the device holder, the lighting body provides fill lighting for the photographing device.
