Detachable Light Shield Panels for Luminaire Light Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light shields are inflexible and inefficient, requiring multiple shields for different light restriction patterns, and add weight and stress to luminaires, limiting precision in light control.
Innovation Solution
A light shield with detachable panels and interlocking arms that can be coupled to a luminaire, allowing for adjustable light distribution by detaching panels and interlocking with other shields to provide finer control over light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fixed light shields are used, then light distribution can be controlled, but flexibility and adaptability are reduced
Solution Approach 1:
The light shield is divided into multiple detachable panels that can be independently removed or retained. Score lines are pre-marked on the shield body to indicate where panels can be detached. This segmentation allows users to create different light restriction patterns by selectively removing panels, providing flexibility without requiring multiple complete shields.
Solution Approach 2:
The light shield transitions from a fixed, static structure to a dynamic, adjustable configuration. Panels can be detached and reattached, and the shield can be rotated or repositioned on the luminaire, allowing the light distribution pattern to be dynamically changed to suit different lighting needs and scenarios.
2Reliability
If conventional light shields are used, then light restriction patterns can be established, but weight and stress on the luminaire increase
Solution Approach 1:
The shield is segmented into detachable panels, allowing users to remove portions that are not needed for the current lighting scenario. This reduces the overall weight of the installed shield while maintaining the necessary light restriction functionality, thereby reducing stress on the luminaire mounting.
3Ease of operation
If conventional light shields are coupled to the luminaire housing, then installation is simplified, but precision of light control is reduced
Solution Approach 1:
An adapter ring serves as an intermediary component between the luminaire and the light shield. The adapter ring is coupled to the luminaire housing, and the light shield is then coupled to the adapter ring. This intermediary allows precise positioning of the shield closer to the light source while maintaining ease of installation through the adapter interface.
4Adaptability or versatility
If multiple conventional light shields are used to achieve different light patterns, then light distribution flexibility is improved, but device complexity and installation effort increase
Solution Approach 1:
Instead of requiring multiple complete light shields, a single shield with segmented detachable panels provides the same flexibility. Users can remove specific panels to create different light patterns, eliminating the need to store and install multiple different shield types.
Solution Approach 2:
A single light shield design with detachable panels serves multiple functions that would otherwise require different specialized shields. The same shield can be configured for various light distribution patterns by selectively detaching panels, making it a universal solution for different lighting scenarios.

AI summary
A light shield includes a main portion and an overlap portion that is substantially perpendicular to the main portion. The main portion includes a first scored area and a base platform disposed below the first scored area. The first scored area includes a plurality of score lines that define one or more detachable panels. The overlap portion includes a second scored area and another base platform. The second scored area includes another plurality of score lines that define one or more detachable overlap panels. Further, the light shield includes a flange that extends substantially perpendicular to and along a length of a base platform of the light shield's main portion. A first interlocking arm extends from a first end of the flange and a second interlocking arm extends from a second end of the flange that is opposite to the first end.
