Lens with Total Internal Reflection for Sparkling Light Effect
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting solutions fail to effectively create a sparkling light effect with high luminous efficiency, as they either lack the necessary optical configuration to converge light beams into focused points or suffer from light loss.
Innovation Solution
A lens with a total internal reflection surface, specifically an elliptic or parabolic curved surface, is designed to adjust and converge light beams into focused sparkling points, minimizing light loss and enhancing luminous efficiency by using dual-function surfaces for both light adjustment and emergence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a lens is used to create sparkling light effect, then light can be converged into focused points, but light loss occurs reducing luminous efficiency
Solution Approach 1:
The patent replaces traditional mechanical light reflection surfaces with a total internal reflection surface. This substitution allows light to be redirected through the lens material itself rather than external mirrors, eliminating light loss at reflection interfaces and achieving both sparkling light effect and high luminous efficiency simultaneously
Solution Approach 2:
The patent changes the optical parameters of the lens by introducing a total internal reflection surface with specific curvature and refractive index characteristics. This parameter change enables the lens to converge light into focused points while maintaining high transmission efficiency, resolving the contradiction between creating sparkling effects and minimizing light loss
2Illumination intensity
If multiple separate components are used to achieve sparkling effect, then light can be adjusted and converged, but device complexity increases
Solution Approach 1:
The patent merges the functions of light adjustment and light convergence into a single integrated lens structure. By combining the incident surface, total internal reflection surface, and emergent surface into one component, the design achieves focused light points without requiring multiple separate optical elements, thus reducing device complexity
Solution Approach 2:
The lens structure performs multiple functions simultaneously: it adjusts light direction, converges light into focused points, and enables total internal reflection. This multi-functionality eliminates the need for separate components dedicated to each function, simplifying the overall optical configuration while achieving the desired sparkling light effect
