Light Guide Ring Segmentation for Uniform Brightness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ring-shaped light emitting structures, either using optical fibers or light emitting elements with lenses, face issues such as limited light emission to a single region, high cost, and uneven brightness due to space constraints.
Innovation Solution
A light emitting structure comprising a light guide ring with connected light guide portions and laterally adjacent light emitting elements, which can be configured to occupy less space and provide uniform brightness through a multi-zone light emitting effect, optionally utilizing a diffuser plate for enhanced light distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If ring-shaped optical fiber is used for light emission, then light can be emitted in a ring shape, but it can only emit light in a single region and forms dark regions at junctions, and the cost is quite expensive
Solution Approach 1:
The light guide ring is divided into multiple light guide portions (first, second, third, and fourth light guide portions) that are connected in sequence. Each light guide portion is associated with separate light emitting elements, allowing independent light emission control. This segmentation eliminates dark regions at junctions by ensuring continuous light emission around the entire ring structure.
2Shape
If light emitting elements are disposed beneath the ring-shaped lens, then ring-shaped light emission can be achieved, but those occupy a large space
Solution Approach 1:
The light emitting elements are arranged laterally adjacent to the light guide portions rather than being disposed beneath a ring-shaped lens. This lateral arrangement in a different spatial dimension reduces the vertical space occupation while maintaining the ring-shaped light emission profile.
3Volume of moving object
If distance between the light emitting elements and the ring-shaped lens is reduced in order to reduce the occupied space, then space occupation is reduced, but it may cause uneven brightness
Solution Approach 1:
The light guide portions act as intermediary structures that receive light from the light emitting elements and guide it along the ring structure. This intermediary mechanism allows the light emitting elements to be positioned laterally adjacent to the light guide portions at an optimized distance, achieving both compact space occupation and uniform brightness distribution through the light guiding function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

The structure achieves uniform brightness and reduced space occupation, enabling a thinner light emitting module with a multi-zone light emitting effect, addressing the limitations of existing technologies.
Implementation Method 1
The light guide ring has a plurality of light guide portions connected in sequence, and each of the light guide portions includes a light source receiving end and a connecting portion opposite to each other
Implementation Method 2
the light emitting structure further includes a diffuser plate disposed beneath the light guide ring, and a portion of a vertical projection region of the diffuser plate is located in the inner region

AI summary
A light emitting structure includes a light guide ring and a plurality of light emitting elements. The light guide ring has a plurality of light guide portions connected in sequence, and each of the light guide portions includes a light source receiving end and a connecting portion opposite to each other, in which one of the light guide portions is connected to another of the light guide portions, and an inner side or an outer side of the one of the light guide portions is connected to the connecting portion of the other of the light guide portions. The light emitting elements are laterally adjacent to the light source receiving ends of the light guide portions, respectively.
