Columnar Lighting Structure for Uniform Ring Illumination in Tight Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting structures face challenges in implementing uniform lighting on the leading end of a columnar member when space is restricted due to coverage by a cover panel or glass, making it difficult to arrange a cylindrical light guiding member.
Innovation Solution
A lighting structure comprising a columnar member, cylindrical member, first and second light guiding members, and a light source, where the first light guiding member is transparent, the second member has reflectivity, and both members work together to guide and diffuse light uniformly around the columnar member, even in restricted spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a cylindrical light guiding member is arranged around a columnar member to achieve uniform lighting, then lighting uniformity is improved, but space availability deteriorates due to coverage by cover panel or glass
Solution Approach 1:
The light guiding function is divided into two separate members: a first light guiding member (transparent) and a second light guiding member (with light diffusion property). This segmentation allows each member to perform its specific function independently, enabling uniform lighting while accommodating space constraints imposed by cover panels or glass.
Solution Approach 2:
A light source member is introduced as an intermediary element positioned between the columnar member and the cover panel/glass. This intermediary light source, combined with the two light guiding members, enables light to be guided and diffused uniformly around the columnar member without requiring additional space that would conflict with the cover panel or glass coverage.
2Device complexity
If space is restricted near the columnar member by cover panel or glass, then structural compactness is improved, but lighting capability deteriorates
Solution Approach 1:
The first light guiding member and second light guiding member are arranged in a nested configuration around the columnar member, with the light source member positioned within the restricted space near the columnar member. This nested arrangement enables the lighting system to fit within the compact space constrained by cover panels or glass while maintaining effective lighting capability.
Solution Approach 2:
The second light guiding member is specifically designed with light diffusion property, changing the optical parameter from light transmission to light diffusion. This parameter change enables the member to distribute light uniformly across the leading end of the columnar member, compensating for the limited space available and maintaining effective lighting capability in a compact structure.

AI summary
In a lighting structure, a columnar member extends in a first direction. A cylindrical member cylindrically extends in the first direction and covers a circumferential surface on a leading end side of the columnar member. A first light guiding member is provided between a light source and the leading end of the columnar member and is provided on a first side of the columnar member. A first member of a second light guiding member has a light transmissive property and a light diffusion property. The first member is provided inside the cylindrical member and provided on a second side of the columnar member. A second member of the second light guiding member has reflectivity and is provided inside the cylindrical member and outside the first member. The second member is interposed between the first light guiding member and the cylindrical member on the first side.
