Light Guide Fixing Means Rear Reflection Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Longer light guides require additional fixing means, which can be visually unappealing and reduce lighting effectiveness due to shadow zones and light absorption, especially when viewed from a height.
Innovation Solution
The second fixing means is integrated into the light guide's rear part above the reflection area, ensuring light is reflected downwards, making it invisible from the front and maintaining light distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a second fixing means is added to the light guide, then the light guide can be securely fastened to the support, but the fixing means becomes visible from the front and creates shadow zones that harm the style effect and reduce lighting quality
Solution Approach 1:
The second fixing means is repositioned from the front viewable area to the rear part of the light guide, changing its spatial dimension. This relocation places the fixing means in a dimension that is not visible from the front, thereby eliminating the visual defect and shadow zone while maintaining securing function
Solution Approach 2:
The rear part of the light guide serves as an intermediary structure that hosts the second fixing means. This intermediary location allows the fixing means to perform its securing function without directly interfering with the light transmission path visible from the front, thus resolving the contradiction between securing reliability and visual quality
2Reliability
If the second fixing means is positioned below the reflection means, then it can secure the light guide, but it creates a magnifying effect and dark zones that reduce lighting effectiveness
Solution Approach 1:
The second fixing means is repositioned vertically above the reflection means instead of below it. This dimensional change in positioning moves the fixing means out of the critical light path area, preventing it from creating magnifying effects and dark zones while maintaining its securing function
Solution Approach 2:
The positioning of the second fixing means is optimized for local quality - placing it in a specific location (rear part above reflection means) where it performs its securing function without negatively affecting the overall lighting quality. This localized optimization resolves the contradiction between securing reliability and lighting effectiveness
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration eliminates visual defects and maintains light efficiency by preventing light absorption and shadow zones, ensuring the fixing means is only visible to observers at a lower height.
Implementation Method 1
comprises an external face which is provided on a portion of a rear part with reflection means which are suitable for reflecting light towards a front part
Implementation Method 2
arranged so as to reflect down the light which has penetrated into it

AI summary
The invention relates to a lighting device (D) including at least one elongate light guide (G) comprising two opposite ends (E1, E2), each of which have a first attachment means (MF1) capable of enabling the attachment thereof to a mounting, and connected via a main portion (PP) suitable for guiding light and comprising an outer surface (FE) having, on part of a rear portion (PR), a reflection means (MR) suitable for reflecting light to a front portion (PV). Said device (D) also includes at least one second attachment means (MF2) which is secured to a selected location on the main portion (PP) on the rear side (PR) thereof and just over the reflection means (MR) so as to reflect light downward, and which is securable onto the mounting.
