Linear Light Fixture Gap Leakage Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Linear light fixtures experience light leakage due to gaps between the lens and the housing, leading to inconsistent light distribution and aesthetic issues.
Innovation Solution
Incorporating an auxiliary optical member with a light diffusion film within the housing to fill these gaps, ensuring that light emitted by the sources passes through the film, thereby maintaining uniform light distribution and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a lens is slotted into the opening in the housing, then light can be emitted through the lens, but gaps between the lens and housing result in light leakage
Solution Approach 1:
An auxiliary optical member is introduced as an intermediary component between the lens and the housing. This member includes a light diffusion film that fills the gap and diffuses light, preventing direct light leakage while maintaining the light emission function through the lens.
Solution Approach 2:
The auxiliary optical member is specifically positioned only in the gap region between the lens and housing, providing localized light diffusion where needed. This allows the lens to maintain its primary light emission function while the auxiliary member addresses the specific problem of light leakage in the gap area.
2Ease of manufacture
If gaps exist between the lens and housing, then the lens can be installed, but light leakage occurs leading to aesthetic issues
Solution Approach 1:
The auxiliary optical member serves as a mediator that fills the gap between lens and housing, maintaining the ease of lens installation while improving the uniformity of light distribution by diffusing light through the gap region.
Solution Approach 2:
The light diffusion film changes the optical parameters of light passing through the gap, transforming direct light into diffused light. This parameter change ensures uniform light distribution and eliminates the aesthetic issues caused by visible light leakage.
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
The auxiliary optical member effectively covers the gaps, ensuring consistent light emission and improved aesthetics by diffusing light uniformly, aligning with industry standards.
Implementation Method 1
the body includes a light diffusion film... allow a portion of light emitted by the plurality of light sources to pass through the light diffusion film

AI summary
A linear light fixture can include a housing that includes at least one wall that forms a cavity. The linear light fixture can also a light board having multiple light sources disposed thereon, where the light sources are arranged in a linear fashion with respect to each other on the light board, where the light board is disposed within the cavity of the housing. The linear light fixture can further include a lens slidably disposed within a receiving feature of the housing. The linear light fixture can also include a first auxiliary optical member disposed within cavity of the housing, where the first auxiliary optical member includes a first body having a first end and a second end, where the first body includes a light diffusion film. The first auxiliary optical member can fill a first gap between the lens and a first side wall of the housing.
