Table Lamp Shadow Projection Plate Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional table lamps primarily focus on light projection and lack the ability to create or enhance the surrounding environment with unique visual effects, such as varying light shadows, which limits their decorative and aesthetic appeal.
Innovation Solution
A light-and-shadow table lamp structure comprising a lamp base with an interior electrical control unit, a shadow projecting plate with a light-transmitting pattern, and a lampshade that encloses the plate and light-emitting elements, allowing light to project and cast dynamic shadows onto external objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional table lamps are designed to provide sole light projection function, then lighting function is achieved, but decorative visual effect and environmental enhancement capability are lacking
Solution Approach 1:
The lamp integrates multiple functions into a single device: the light-emitting element provides illumination, the shadow projecting plate creates decorative shadow patterns, and the lampshade diffuses and directs light. This multi-functional design allows the lamp to serve both practical lighting and decorative purposes simultaneously, resolving the contradiction between functional versatility and structural complexity.
Solution Approach 2:
The invention merges the light source, shadow projection mechanism, and light diffusion structure into a unified integrated assembly. The light-emitting element, shadow projecting plate, and lampshade are combined in a single configuration where each component contributes to both lighting and decorative functions, achieving functional versatility without proportionally increasing structural complexity.
2Illumination intensity
If a light-transmitting three-dimensionally shaped decoration is attached to a water lamp, then visual effect is enhanced, but functional limitation remains as lighting variation is restricted to the outside of the main body
Solution Approach 1:
The shadow projecting plate introduces a new dimensional aspect to light projection by creating two-dimensional shadow patterns on surrounding surfaces. This transforms the lighting effect from simple illumination to dynamic shadow casting, enhancing lighting variation while expanding functional capability through the addition of patterned light transmission.
3Shape
If table lamps are designed with unique art shapes for beautifying environment, then decorative effect is improved, but ability to create varying light shadows is generally not available
Solution Approach 1:
The shadow projecting plate features localized light-transmitting patterns with specific geometric designs that create distinct shadow effects. Different regions of the plate have different pattern densities and configurations, allowing the lamp to produce varied shadow patterns while maintaining an aesthetically pleasing overall structure, thus preserving both shape美感 and shadow projection capability.
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 solution enables a table lamp to create a visually engaging effect by projecting light and shadows, enhancing the lamp's decorative and environmental impact while providing both functional lighting and aesthetic appeal.
Implementation Method 1
Light from the at least one light-emitting element projects outward to cast a shadow of the light-transmitting pattern of the shadow projecting plate onto an external object
Implementation Method 2
cast a shadow of the light-transmitting pattern of the shadow projecting plate onto an external object so as to achieve an effect of varying light projection to form a light shadow at the outside

AI summary
A light-and-shadow table lamp structure includes a lamp base, a shadow projecting plate, and a lampshade. The lamp base includes at least one light-emitting element arranged on a top thereof. The shadow projecting plate is arranged above the at least one light-emitting element to correspond thereto. The shadow projecting plate is provided with a light-transmitting pattern. The lampshade is arranged on the top of the lamp base and circumferentially encloses a periphery of the at least one light-emitting element. The light-transmitting pattern is arranged to project, by means of light from the at least one light-emitting element, a shadow of the light-transmitting pattern onto an external object.
