Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting setups for video content creation and live events often result in shadows forming near the neck of subjects due to ceiling-mounted lighting, disrupting viewer concentration and video quality.
Innovation Solution
A table-mounted lighting device with a housing featuring a light transmitting surface and multiple transverse light seating recesses, a flexible LED lighting part, a power source, brightness adjustment mechanism, and an adapter for coupling to a table, which directs light specifically to the neck area to prevent shadows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If ceiling-mounted lighting is used to illuminate the subject, then overall illumination is provided, but shadows form near the neck of the subject
Solution Approach 1:
The lighting system is segmented into multiple independent lighting devices positioned at different locations (ceiling-mounted lights and table-mounted lights). The table-mounted lighting device is specifically positioned to illuminate the neck area, separating the overall illumination function from the shadow-prevention function, thereby resolving the shadow problem without compromising overall lighting coverage
Solution Approach 2:
The table-mounted lighting device acts as an intermediary lighting source between the ceiling-mounted lights and the subject's neck area. It fills in the shadow regions that the ceiling lights create by providing additional light from a different angle, effectively eliminating the harmful shadows near the neck
2Object-affected harmful factors
If additional lighting devices are installed in front of the subject, then shadow formation is reduced, but device complexity increases
Solution Approach 1:
The table-mounted lighting device is designed with multi-functionality, serving both as a structural support element (table attachment) and as a lighting device. By integrating the lighting function into the table structure, the system reduces the need for separate, complex lighting arrangements while effectively addressing shadow formation
Solution Approach 2:
The lighting device is merged with the table structure through the adapter part, combining the support function of the table with the illumination function of the lighting device. This integration simplifies the overall system configuration by eliminating the need for separate mounting structures and reducing the number of independent components
3Illumination intensity
If multiple transverse rows of lighting seating recesses are formed, then uniform light distribution is achieved, but manufacturing complexity increases
Solution Approach 1:
The housing structure incorporates multiple transverse rows of lighting seating recesses with varying inner areas, where each row is specifically designed with different dimensions to optimize light distribution at different positions. This local differentiation in recess dimensions allows precise control over light intensity and distribution patterns without requiring complex manufacturing processes
Solution Approach 2:
The design utilizes parameter changes in the dimensions of lighting seating recesses across different transverse rows. By systematically varying the inner area parameters of each recess, the system achieves uniform light distribution through geometric optimization rather than complex manufacturing techniques, making the housing easier to fabricate while maintaining lighting uniformity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively prevents shadows near the neck, enhancing image quality and content quality by providing uniform lighting, and can be easily attached and detached for versatile use.
Implementation Method 1
a lighting part installed in an interior of the housing, and that irradiates light toward a vicinity of a neck
Implementation Method 2
a housing having a light transmitting surface which light transmits

AI summary
Disclosed is a lighting device for a table, which supplies light toward a shade of a lighting object such that a shade formed in the vicinity of the neck of the lighting object due to a lighting of a ceiling installed in an interior space, such as a studio, in which an image of a subject is photographed or a space, such as a stage, for a lecturer.
