Solution Overview
Problem
Existing light emitting devices struggle to provide both spotty and diffuse lighting effects efficiently, often requiring complex and expensive optical constructions with low optical efficiency, limited flexibility, and difficulty in user selection between lighting effects.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a thin transparent or translucent sleeve is used to seal the LED strip, then the LED strip maintains flexibility, but the optical efficiency is low and the lighting effect is limited
Solution Approach 1:
The patent employs a composite sleeve structure combining transparent/translucent material and diffuse material in different sections. The transparent section (first part) allows direct light transmission for high optical efficiency, while the diffuse section (second part) provides light scattering for homogeneous lighting effect. This composite material approach resolves the contradiction by allowing the sleeve to maintain flexibility while significantly improving optical efficiency and providing multiple lighting effects.
2Illumination intensity
If complex optical constructions are used to achieve diffuse lighting effect, then the lighting quality improves, but the device complexity and cost increase
Solution Approach 1:
The patent merges the sealing function and the optical modulation function into a single integrated sleeve component. The sleeve simultaneously provides mechanical protection, light transmission, and light diffusion without requiring separate optical elements like diffusers, reflectors, or lenses. This merging approach achieves high-quality diffuse lighting effect while minimizing device complexity and component count.
Solution Approach 2:
The sleeve is designed as a multi-functional component that performs multiple roles: mechanical sealing/protection of the LED strip, structural support, and optical modulation (both direct transmission and diffuse scattering). This universal design eliminates the need for multiple separate components, reducing device complexity while maintaining high lighting effect quality.
3Adaptability or versatility
If multiple components are used to achieve both spotty and diffuse lighting effects, then the lighting versatility improves, but the manufacturing cost and assembly complexity increase
Solution Approach 1:
The patent implements a dynamic lighting system where the lighting effect can be switched between spotty and diffuse modes by changing the orientation of the sleeve relative to the LED strip. When the transparent part faces the observer, direct light transmission creates spotty effect; when the diffuse part faces the observer, light scattering creates homogeneous effect. This dynamic switching capability provides lighting versatility without requiring multiple separate components or complex assembly procedures.
