Fibrous Lighting Fixture Surface for Light Diffusion and Texture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional formed lighting fixtures lack decorative and functional enhancements, such as light refraction and texture, due to the absence of a dimension of material extending from their surface.
Innovation Solution
Incorporating a fibrous layer extending from the outer surface of the lighting fixture, which can be electrostatically flocked to create a textured, colored, or fur-like appearance and diffuse light, enhancing the fixture's decorative and functional aspects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a flat cover material layer is used, then the fixture structure is simple, but the decorative appearance and light refraction effects are limited
Solution Approach 1:
The patent applies dimensionality change by adding a fibrous layer that extends outward from the flat cover material surface, transforming the two-dimensional flat surface into a three-dimensional textured surface. This creates multiple dimensions of material that enable light refraction, diffusion, and decorative effects while maintaining the basic fixture structure.
2Illumination intensity
If a fibrous layer is added to extend from the surface, then light diffusion and decorative effects are improved, but the fixture structure becomes more complex
Solution Approach 1:
The patent uses composite materials by combining the cover material layer with a fibrous layer to create a multi-layered structure. The fibrous layer consists of numerous fine fibers that collectively provide light diffusion and decorative effects while being applied as a unified component to the cover material surface.
Solution Approach 2:
The fibrous layer is applied to specific portions or the entire surface of the cover material layer, allowing different regions to have different optical properties. This enables localized light diffusion and decorative effects where needed while maintaining the structural integrity of the overall fixture.
3Reliability
If the cover material is made transparent for light transmission, then light refraction is enabled, but the textured appearance and weather durability are reduced
Solution Approach 1:
The patent segments the lighting fixture into distinct functional layers: a transparent cover material layer for light transmission and refraction, and a fibrous layer for texture and weather protection. This segmentation allows each layer to perform its specific function optimally without compromising the other.
Solution Approach 2:
The fibrous layer is nested on the outer surface of the transparent cover material layer, creating a nested structure where the inner transparent layer enables light transmission while the outer fibrous layer provides texture and weather durability. Both layers work together in a hierarchical arrangement.

Implementation Method 1
the fibrous layer is configured to provide certain functional and decorative characteristics to the formed lighting fixture, such as providing a textured, colored, or fur-like appearance, or light-diffusion
Implementation Method 2
the plurality of fibers are electrostatically flocked to the outer surface of the formed lighting fixture
Implementation Method 3
the cover material 3 is a transparent refracting material that refracts the light emanating from the light source 2
Data Source
AI summary
An improved formed lighting fixture having a frame, a light source, a cover layer coupled to the frame, and a fibrous layer coupled to the cover layer, in which the frame is formed by gathering a plurality of rods and profiled in a specific contour, the light source is configured to provide light from inside the frame and out through the cover layer onto the fibrous layer. The fibrous layer is configured to provide decorative and functional aspects to the lighting fixture, including, in some embodiments, a contoured or fur-like appearance, or where the fibrous layer has light-diffusive properties, a dazzling glow effect when light from the light source is diffused.
