Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light strip structures suffer from dark areas and light spots due to the fixed angle of emission of LED beads, leading to uneven illumination, visual discomfort, and energy waste, with existing solutions increasing costs and complexity.
Innovation Solution
A light strip structure incorporating a light transmitting member, light blocking member, and capsule light dispersing member, where light beads are uniformly distributed and wrapped by a capsule light dispersing member to scatter light evenly, combined with reflective and scattering layers to enhance uniformity and consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the arrangement density of light beads is increased to reduce dark areas, then the illumination uniformity is improved, but the manufacturing cost increases and heat dissipation difficulty increases
Solution Approach 1:
The patent introduces a light-redirecting structure as an intermediary component between the light beads and the surrounding environment. This structure redirects light that would otherwise be emitted sideways or downwards into the forward direction, effectively utilizing the light from each bead to illuminate the area in front of it, thereby reducing dark areas without increasing bead density
Solution Approach 2:
The patent changes the emission direction parameter of the light beads by using the light-redirecting structure to alter the light propagation angle. Instead of light radiating in all directions from each bead, the structure modifies the emission parameters to concentrate light in the forward direction, improving illumination uniformity without adding more beads
2Illumination intensity
If special packaging materials or optical lenses are used to redistribute light, then the illumination uniformity is improved, but the process complexity and cost increase
Solution Approach 1:
The patent employs a light-redirecting structure that functions as a thin optical element integrated into the packaging. This structure is simple in form but effective in function, redirecting light without requiring complex multi-layer optical systems or expensive specialized materials, thus maintaining process simplicity while achieving uniform illumination
3Ease of manufacture
If light beads are arranged at certain distances on the circuit board, then the manufacturing process is simple, but dark areas and light spots are formed between the beads
Solution Approach 1:
The light-redirecting structure serves as a mediator that bridges the gap between individually spaced light beads. It captures light that would otherwise create hot spots and redirects it to fill in the dark areas between beads, maintaining the simple spaced arrangement while achieving uniform illumination
Solution Approach 2:
The patent modifies the light propagation parameters by introducing the light-redirecting structure, which changes the direction and distribution of light from each bead. This allows the maintenance of simple spaced bead arrangements while transforming the light distribution pattern to eliminate dark areas and light spots

AI summary
A light strip structure is provided, which includes a light transmitting member, a light blocking member, a wire, and a capsule light dispersing member. The light transmitting member is provided with an accommodating cavity along a length direction, the wire is provided in the accommodating cavity and is provided with a plurality of light beads, and the capsule light dispersing member is wrapped around the light beads. The light blocking member is connected to the light transmitting member, and light emitted by the light beads diverges through the capsule light dispersing member and is excited along the light transmitting member. The present disclosure can fully and uniformly spread the light emitted by the light beads along the entire length direction of the lamp strip, thereby avoiding dark areas between adjacent light beads caused by insufficient coverage of light; at the same time, it effectively eliminates the phenomenon of light spots.
