Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glare-reducing optic assemblies for lighting scenarios, particularly with LED sources, are inefficient and require complex constructions, leading to reduced lighting efficiency and glare issues.
Innovation Solution
An optic assembly comprising a light entrance surface, first and second light emission structures, and a body that guides light to both structures without external loss, using a simple construction with plastic materials to achieve glare reduction and efficient light distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a diffusor is added to an optic assembly to reduce glare, then glare is reduced, but lighting efficiency is reduced
Solution Approach 1:
The optic assembly is segmented into multiple light emission structures (first and second types) with different functions. The first structures provide directed light emission for efficiency, while the second structures provide diffuse emission for glare reduction. This segmentation allows simultaneous achievement of both goals without compromising lighting efficiency.
2Object-affected harmful factors
If light sources with large surface area emission are used to reduce glare, then glare is reduced, but the choice of light sources is limited
Solution Approach 1:
Instead of changing the light source characteristics (which would limit choices), the solution adds a spatial dimension by incorporating multiple light emission structures at different positions and orientations within the optic assembly. This allows glare reduction through geometric arrangement rather than source modification, maintaining versatility in light source selection.
3Object-affected harmful factors
If multiple lenses and scattering bodies are used to reduce glare as shown in US 2022/0252775 A1, then glare is reduced, but the construction becomes complex
Solution Approach 1:
The optic assembly merges multiple light emission structures into a single integrated optical system with a unified body. The first and second light emission structures are combined within one assembly, eliminating the need for separate components and complex arrangements while achieving glare reduction through their coordinated optical functions.
4Ease of manufacture
If light is allowed to leave the body before being guided to light emission structures, then manufacturing is simpler, but light loss increases
Solution Approach 1:
The optic body is designed with internal light guiding structures that preliminarily direct light from the light source to the light emission structures before light exit. This preliminary internal guidance ensures efficient light transport without requiring complex external optical components, maintaining manufacturing simplicity while preventing light loss.
