Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lamps with single light sources and flat exiting surfaces result in uneven light distribution and monotonous visual effects due to non-flat lamp covers and single light incident surfaces, leading to low light intensity and aesthetic issues.
Innovation Solution
An optical device comprising multiple lens units with microstructured surfaces arranged in a high and low configuration, each with a light incident and exiting side, providing even light collection and aesthetic enhancement by integrating microstructured surfaces for diverse lighting effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single light source and single light incident surface are used, then the device complexity is reduced, but the light distribution uniformity and visual aesthetic are worsened
Solution Approach 1:
The optical device is divided into multiple lens units (first, second, third lens units), each with its own light incident surface and light exiting surface. This segmentation allows each lens unit to independently process and distribute light, improving overall light distribution uniformity while maintaining manageable device complexity through modular design
Solution Approach 2:
Each lens unit is equipped with microstructured surfaces at specific locations (light exiting surfaces of first and second lens units, and light incident surface of third lens unit). These localized microstructures create different light refraction and scattering effects in different regions, achieving uniform light distribution and aesthetic visual effects without requiring complete redesign of the entire device
2Manufacturing precision
If a flat light exiting surface is used, then the manufacturing precision is improved, but the light collection effect and visual aesthetic are worsened due to non-flat lamp cover
Solution Approach 1:
The patent introduces microstructured surfaces that add microscopic dimensional variations to the light exiting surfaces. These microstructures create height differences and surface relief features that compensate for the non-flat lamp cover geometry, enabling uniform light collection and distribution without requiring the main surface to be perfectly flat
Solution Approach 2:
The microstructured surfaces modify the physical parameters of the light exiting surfaces by introducing controlled height variations and surface textures. This changes the light interaction characteristics (refraction, scattering) at the micro-scale, improving light collection efficiency and distribution uniformity while maintaining macro-scale manufacturability
