Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting assemblies with light pipes fail to effectively create three-dimensional dynamic images using light sources and optical elements.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple light pipe assembly is used, then the device complexity is reduced, but the ability to create three-dimensional dynamic images is insufficient
Solution Approach 1:
The light pipe assembly is divided into multiple functional segments: a light guide portion for light transmission, a collimating portion with micro-prisms for directional control, a diffusing portion for light scattering, and a light emitting portion. Each segment performs a specific optical function, enabling complex 3D dynamic image creation while keeping individual components relatively simple and manageable.
2Illumination intensity
If multiple optical elements are added to create three-dimensional images, then the image quality and depth perception are improved, but the device complexity increases
Solution Approach 1:
Multiple optical elements (collimating micro-prisms, diffusing particles, light guide structures) are merged into a single integrated light pipe assembly. The collimating portion, diffusing portion, and light guide portion are combined in one continuous structure, reducing the need for separate components while achieving complex optical effects for 3D dynamic image creation.
Solution Approach 2:
The light pipe assembly serves multiple functions simultaneously: it guides light from the light source, collimates the light rays, diffuses the light distribution, and projects the final image. This multi-functionality is achieved within a single integrated structure, avoiding the need for separate devices for each optical function.
3Stability of the object's composition
If light is collimated and diffused through multiple stages, then the illumination uniformity is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The optical properties of the light pipe are modified by changing material parameters and structural characteristics. The collimating portion uses specific micro-prism geometries with controlled refractive indices, while the diffusing portion incorporates particles with varying sizes and concentrations. These parameter variations enable precise control over light distribution and uniformity while accommodating standard manufacturing tolerances.

Data Source
AI summary
A light-pipe lighting apparatus includes a light source with a collimating light pipe disposed adjacent the light source. An optical sheet is disposed adjacent the collimating light pipe opposite the light source. A mask is disposed adjacent the optical sheet opposite the collimating light pipe. A projection light pipe is disposed adjacent the mask and opposite the optical sheet. Light emitted from the light source is modified as it passes through the collimating light pipe, the optical sheet, the mask, and the projection light pipe thereby projecting an illuminated image. Based on patterns of transparent portions of the mask, corresponding patterns of illuminated images are projected from the light-pipe lighting apparatus.
