Refractive Elements for Dynamic Lighting Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Decorative lighting apparatuses typically appear static and uninteresting from different viewing angles, lacking dynamic visual appeal as they do not change with the viewer's position.
Innovation Solution
Incorporation of a structure with light emitting elements and refractive elements, where the light emitting elements illuminate the refractive elements, creating a changing visual effect as the viewer moves due to the varying refractive angles and light dispersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a light is located above a reflective surface, then the lighting apparatus can be constructed simply, but the decoration looks very similar from different viewing angles
Solution Approach 1:
The patent introduces refractive elements as an intermediary component between the light source and the viewer. These refractive elements modify the light path by refracting it in multiple directions, creating a dynamic viewing effect without adding complex mechanical structures. The refractive elements serve as a mediator that transforms simple light into directionally varied illumination.
Solution Approach 2:
The patent changes the optical parameters of the light by introducing refractive elements with specific refractive indices and geometric shapes. By controlling the refractive properties and arrangement of these elements, the system achieves varied viewing angles while maintaining a simple overall structure. The parameter changes occur in the light's propagation path rather than in the structural complexity.
2Adaptability or versatility
If refractive elements are added to create dynamic visual effects, then viewing angle variation is improved, but device complexity increases
Solution Approach 1:
The patent segments the refractive function into multiple discrete refractive elements that can be independently arranged and positioned. Each element handles a specific portion of the light path, and their collective arrangement creates the overall dynamic viewing effect. This segmentation allows for modular design and simplified manufacturing while achieving complex optical behavior.
Solution Approach 2:
The patent employs curved or faceted surfaces on the refractive elements to manipulate light paths in multiple directions. The curved geometry of these elements enables them to refract light dynamically based on viewing angles, achieving visual complexity through geometric shape rather than structural complexity. The curvature of the refractive elements is the key feature that enables directionally varied illumination.
