Dual-Cover Optical Device for Shadow-Free Flowing Light
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection lamps with flowing effects suffer from complex structures and marginal shadows due to the rotation of a water ripple plate, leading to poor viewing experiences with single directional lighting effects.
Innovation Solution
An optical device with a flowing effect utilizing a light bead, first and second cover bodies with textures, and a driving mechanism that induces relative motion between the cover bodies, allowing light to distort and deform through multiple optical path changes, creating a dispersed and flowing light shadow effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a water ripple plate rotates in front of the LED light source to create flowing effects, then a dynamic pattern is projected onto the wall, but a marginal shadow is formed in the flowing direction which affects the lighting effect
Solution Approach 1:
The patent removes the water ripple plate from the optical path and replaces it with a transparent cover body having a specific surface shape. This extraction eliminates the marginal shadow problem while preserving the flowing effect through the surface geometry of the cover body rather than through a rotating plate.
Solution Approach 2:
The patent introduces a transparent cover body with a specific surface shape as an intermediary element between the light source and the projection surface. This cover body acts as a mediator that creates the flowing effect without casting marginal shadows, replacing the traditional water ripple plate function.
2Adaptability or versatility
If the structure combines LED light source, condensing lens, water ripple plate, and camera to achieve flowing and projection effects, then the lighting effect is enhanced, but the structure becomes complex
Solution Approach 1:
The patent merges the functions of multiple components (LED light source, condensing lens, water ripple plate, camera) into a simplified structure where a transparent cover body with a specific surface shape integrates the flowing effect generation and projection functions, reducing the number of separate components.
Solution Approach 2:
The transparent cover body serves multiple functions simultaneously: it acts as a protective cover, creates the flowing effect through its surface geometry, and enables projection without requiring separate dedicated components for each function.
3Adaptability or versatility
If a single water ripple plate is used to create flowing effects, then the projection effect is achieved, but the viewing effect is poor due to single directional lighting
Solution Approach 1:
The patent employs an asymmetric surface shape on the transparent cover body that creates multiple optical paths and viewing angles. The asymmetric geometry ensures that the flowing effect is visible from different directions, improving the viewing effect compared to symmetric single-direction lighting.
Solution Approach 2:
The patent transitions from a single-dimensional rotating plate to a three-dimensional transparent cover body with a specific surface shape. This dimensional change enables light to be dispersed and projected in multiple directions simultaneously, creating a more versatile viewing effect.
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 achieves a soft and realistic flowing lighting effect by dispersing the optical path through relative motion and superposition of optical distortions, eliminating marginal shadows and enhancing the viewing experience.
Implementation Method 1
the light emitted by the light bead will distort and/or deform in the process of passing through the first cover body and the second cover body
Implementation Method 2
the optical path can be completely dispersed, and projected light shadows have a flowing effect

AI summary
An optical device with a flowing effect includes: a light bead; a first cover body, having a first internal space, wherein the light bead is located in the first internal space; a second cover body, located outside the first cover body, wherein lines are provided on surfaces of both the first cover body and the second cover body; a driving mechanism, wherein the first cover body and the second cover body undergo relative motion under the driving of the driving mechanism; and a stand body, wherein the light bead and the driving mechanism are both fixed on the stand body. In the present disclosure, with the relative motion between the two lamp covers, an optical path will move to change all the time. The optical path distorts and/or deforms after passing through the first cover body, and will distort and/or deform again when passing through the second cover body.
