Anti-Glare Light Strip Co-Extrusion for Dust-Resistant Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional neon light strips lack professional optical performance, with honeycomb anti-glare plates having poor bonding, dust accumulation, and ineffective glare reduction, leading to unsatisfactory anti-glare effects.
Innovation Solution
Manufacture anti-glare light strips through one or two co-extrusion processes, integrating an anti-glare sheet with a light diffusion and light-transmitting layer using silica gels, ensuring the anti-glare sheet is sealed within the light body to prevent dust accumulation and enhance glare reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If ink screen printing or gel bonding of honeycomb anti-glare plates is used, then anti-glare function is provided, but bonding process is complicated and bonding effect is poor
Solution Approach 1:
The patent merges the anti-glare sheet bonding process with the light strip manufacturing process by using co-extrusion technology. The anti-glare sheet is integrated into the light diffusion layer during a single extrusion operation, eliminating separate bonding steps and achieving strong, reliable bonding without manual intervention.
Solution Approach 2:
The patent replaces mechanical bonding methods (screen printing, manual bonding) with a unified extrusion process. The anti-glare sheet is bonded through the extrusion of light diffusion material that encapsulates it, transforming the bonding mechanism from mechanical adhesion to integrated material formation.
2Area of stationary object
If honeycomb anti-glare plates are bonded only to two sides, then some anti-glare effect is achieved, but bonding area is small and integrity is poor
Solution Approach 1:
The patent transitions from bonding anti-glare plates to only two sides of the light strip to bonding the anti-glare sheet throughout the entire light diffusion layer. The co-extrusion process enables the anti-glare sheet to be integrated in all dimensions, achieving complete coverage and superior integrity.
3Productivity
If conventional light strip manufacturing process is used, then production is simple, but dust accumulates in holes and blocks reflective surface
Solution Approach 1:
The patent extracts and eliminates the problematic honeycomb structure with holes from the light strip design. By using a solid anti-glare sheet integrated into the light diffusion layer, the design removes the cavities where dust would accumulate, while maintaining the anti-glare function through the sheet's grid pattern.
Solution Approach 2:
The patent uses a thin anti-glare sheet with grid pattern as the anti-glare element, which is integrated into the light diffusion layer. This thin film structure provides anti-glare functionality without creating deep cavities that would trap dust, unlike the conventional honeycomb plate structure.
4Illumination intensity
If honeycomb coating is screen printed, then appearance effect is achieved, but three-dimensional effect is missing and UGR reduction is insufficient
Solution Approach 1:
The patent uses a composite structure where the anti-glare sheet with grid pattern is integrated within the light diffusion layer material. This composite construction provides both the appearance effect and the three-dimensional optical control needed to effectively reduce UGR, overcoming the limitations of simple screen-printed coatings.

Function Achieved in This Case
The anti-glare sheet effectively blocks scattered light, achieving lower Unified Glare Rating (UGR) values and maintaining a clean, uniform luminous effect by preventing dust accumulation and ensuring high surface flatness.

AI summary
A manufacturing method of an anti-glare light strip is provided. The anti-glare light strip includes a light body. The light body includes a light diffusion layer, light shielding layers respectively arranged on two sides of the light diffusion layer, light body shells respectively arranged on outer sides of the light shielding layers, and an anti-glare sheet. A top portion of the light diffusion layer and top ends of the light shielding layers jointly define a mounting groove. A one-time co-extrusion process, two times of co-extrusion processes, or a co-extrusion process and a sleeve process are adopted to manufacture the anti-glare light strip. After processing, the light-transmitting layer has good sealing and high surface flatness. There is no holes on a surface of the anti-glare light strip and there is no dust accumulation, thus avoiding affecting a luminous effect.
