Lighting Assembly Light Barrier Prevents Color Bleeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional illuminated signs, such as those using neon tubes or LEDs, face challenges in achieving uniform and brightly colored light distribution, with LEDs often appearing as discrete points of light and requiring multiple units to simulate neon brightness, and experiencing interference between different colored light sources.
Innovation Solution
A lighting assembly design featuring a housing assembly with first and second light sources, where light barriers are used between transparent or translucent covers to prevent interference, and point light sources are spaced optimally to create a continuous, uniform appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If neon tubes are used to provide uniformly distributed and brightly colored light, then illumination quality is improved, but energy consumption increases and service life decreases
Solution Approach 1:
The patent divides the illumination system into multiple discrete LED light sources arranged in a linear array, with each LED acting as an independent segment. This segmentation allows for precise control of light distribution while reducing overall energy consumption compared to a single neon tube, as LEDs are inherently more energy-efficient gas discharge devices.
2Use of energy by moving object
If a series of LEDs are used to illuminate signs, then energy consumption is reduced, but light distribution uniformity deteriorates and the appearance becomes discrete points of light
Solution Approach 1:
The patent introduces a light diffuser as an intermediary element between the discrete LED light sources and the sign surface. This diffuser mediates the light distribution by scattering and redistributing the light from multiple LED points, transforming the discrete point sources into a continuous, uniform illumination pattern that eliminates the appearance of individual LED points while maintaining energy efficiency.
3Adaptability or versatility
If multiple colored LED light sources are used within the same illuminated sign, then color variety is improved, but light interference and bleeding between different colored lights occurs
Solution Approach 1:
The patent spatially segments different colored LED light sources into distinct physical zones within the housing, with each color group positioned in a separate section. This segmentation prevents overlapping light paths and eliminates bleeding between colors, allowing multiple colored LEDs to coexist in the same sign without interference, thereby maintaining color variety while avoiding harmful light mixing.

Function Achieved in This Case
The solution provides an enhanced visual appearance with uniform light distribution and prevents bleeding between different colored lights, offering a cost-efficient and visually appealing alternative to traditional illuminated signs.
Implementation Method 1
A light barrier is disposed on the outer cover to block light from the second light source

AI summary
A lighting assembly includes a housing assembly, a first light source located within the housing assembly, and a second light source located within the housing assembly. A first cover is positioned relative to the first light source so that the first light source is able to illuminate the first cover. A second cover is positioned relative to the second light source so that the second light source is able to illuminate the second cover. A light barrier is disposed between the first and second covers. The light barrier is configured to prevent interference between the first light source and the second light source.
