Segmented Optical Guiding Body for Moving Light Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing illuminating devices with optical sources at both ends of an optical guiding member face challenges in maintaining visibility while avoiding increased size and manufacturing costs as the length of the optical guiding member increases, due to the need for longer wire leads and substrates.
Innovation Solution
The illuminating device features a configuration with linear optical guiding members side by side, where one member's luminance decreases towards the end and the other's increases, with optical sources only at one end, controlled to create a moving bright region, reducing the need for extended substrates and wire leads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If optical sources are provided at both ends of the optical guiding member to enable light visibility movement, then the light visibility is improved, but the wire lead length and substrate length must be increased, leading to increased device size and manufacturing cost
Solution Approach 1:
The optical guiding members are divided into multiple linear segments arranged side by side in the width direction. Each segment has optimized luminance distribution characteristics, allowing the system to achieve moving light visibility without requiring optical sources at both ends of a single long guiding member. This segmentation enables compact arrangement and reduces wire lead length.
Solution Approach 2:
Different luminance distribution characteristics are assigned to different optical guiding members. Specifically, one member has luminance decreasing toward the end while another has luminance increasing toward the end. This local quality differentiation enables the creation of moving bright regions through controlled lighting sequences, achieving light visibility movement without extending substrate or wire lead length.
2Illumination intensity
If optical sources are provided at both ends of the optical guiding member to enable light visibility movement, then the light visibility is improved, but the substrate length must be increased, leading to increased device size and manufacturing cost
Solution Approach 1:
The system uses multiple segmented optical guiding members with different luminance distributions instead of a single long guiding member requiring dual-end sources. This segmentation allows the substrate to be compact while still achieving the effect of moving light visibility through coordinated control of the segmented members.
Solution Approach 2:
The invention changes the luminance distribution parameters of the optical guiding members from uniform or symmetric distributions to asymmetric distributions (one decreasing toward end, another increasing toward end). This parameter change enables the creation of moving bright regions through temporal control, eliminating the need for extended substrate length.
3Illumination intensity
If the optical guiding member length is increased to accommodate longer wire leads, then the light visibility movement is maintained, but the device size increases
Solution Approach 1:
The optical guiding members are arranged side by side in the width direction rather than extending in the longitudinal direction. This dimensional change allows the system to achieve light visibility movement along the longitudinal axis while keeping the physical device length compact, as the multiple members are stacked in the width dimension.

AI summary
An illuminating device may include an optical guiding body configured to dispose linear optical guiding members side by side, the linear optical guiding members guiding light incident from one end side in a longitudinal direction to another end side. The illuminating device may also include optical sources to emit light toward corresponding linear optical guiding members. The optical guiding body may include first and second optical guiding members adjacent in a width direction. A luminance distribution of the light in the longitudinal direction emitted from the first optical guiding member becomes darker, and that emitted from the second optical guiding member becomes brighter, according to being closer to the other end side from the one end side. The illuminating device may further include a control unit configured to light up the optical sources of the first and second optical guiding members in order and thereafter, light them out in order.
