Rotating Lampshade for Adjustable Starry Sky Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atmosphere lamps have a single lighting effect that cannot adapt to different usage scenarios and environments, such as low-brightness settings, where they often produce glaring light and lack the ability to provide softer illumination and varied decorations.
Innovation Solution
A starry sky aurora atmosphere lamp with an integrated lampshade, featuring a main light source, multi-layer housing with an inner light-gathering cover and semi-obscuring outer cover, and auxiliary light sources, which allows for adjustable lighting effects by rotating the multi-layer housing to change the light intensity and pattern, including the use of gear sets and light effect adjustment plates to project diverse light-and-shadow patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the atmosphere lamp uses a single lighting effect design, then the device complexity is reduced, but the adaptability to different usage scenarios and environments deteriorates
Solution Approach 1:
The lampshade is designed to be rotatable relative to the base, allowing dynamic adjustment between different lighting effects (projection mode and ambient illumination mode). This mechanical movement enables a single device to adapt to multiple usage scenarios without requiring multiple separate devices or complex electronic switching mechanisms.
Solution Approach 2:
The lampshade serves multiple functions: it acts as a projection screen when rotated to a specific position, and as a light-diffusing lampshade when rotated to another position. This multi-functionality allows the same structural component to provide different lighting effects, resolving the contradiction between versatility and complexity.
2Illumination intensity
If the lampshade is made transparent to allow light projection, then the illumination intensity is improved, but the light scattering and glare increase
Solution Approach 1:
The lampshade material has different optical properties at different locations: the front surface is transparent for light projection, while the back surface contains light-scattering particles for ambient diffusion. This local differentiation of material properties allows the same component to simultaneously provide strong projection and reduce glare without compromising either function.
Solution Approach 2:
The lampshade uses a composite material structure combining transparent plastic with embedded light-scattering particles. This composite approach allows the material to exhibit both transmission and scattering properties, enabling the lamp to project light effectively while preventing harmful glare and scattering in unwanted directions.
3Object-affected harmful factors
If the lampshade is made opaque to reduce light scattering, then the glare is reduced, but the light projection capability deteriorates
Solution Approach 1:
The lampshade is segmented into functional zones: a transparent front portion for light reception and projection, and an opaque back portion with light-scattering particles for ambient diffusion. This segmentation allows each portion to optimize its optical properties for its specific function, resolving the contradiction between projection capability and glare reduction.
4Adaptability or versatility
If the lampshade is fixed to the base, then the device complexity is reduced, but the adaptability to different lighting effects deteriorates
Solution Approach 1:
The lampshade is connected to the base through a rotational joint, enabling it to move between fixed and adjustable positions. This simple mechanical dynamic connection allows the lampshade to be rotated to different angles to achieve various lighting effects (projection vs. ambient), providing adaptability without requiring complex electronic controls or multiple components.

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 lamp can emit appropriate lighting effects according to environmental changes, improving aesthetic appeal and preventing light from projecting onto buildings while providing decoration and illumination, with enhanced viewing angles and adjustable light intensity.
Implementation Method 1
an inner light-gathering cover and a semi-obscuring outer cover covering a surface of the inner light-gathering cover
Implementation Method 2
a semi-obscuring outer cover covering a surface of the inner light-gathering cover... The semi-obscuring outer cover reduces an intensity of a transmitted light

AI summary
A starry sky aurora atmosphere lamp with an integrated lampshade is provided, including a base, a main light source, a multi-layer housing, and a connector. The main light source is arranged at a center of the base and can project light upwards to form a starry sky atmosphere light. The multi-layer housing can cover the base, such that the main light source is located within an accommodating space formed between the base and the multi-layer housing. The multi-layer housing includes an inner light-gathering cover and a semi-obscuring outer cover covering a surface of the light-condensing inner cove. The connector connects the base with the multi-layer housing. When the multi-layer housing is rotated to cover the base, the multi-layer housing and the base have integral and continuous appearance, and the starry sky atmosphere light is automatically changed to colored glaze light of a small night lamp.
