Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing illumination devices with multiple light sources face challenges in ensuring consistent light distribution due to deviations in lenses, leading to inconsistent illumination effects.
Innovation Solution
A lens combination comprising a first and second lens, both with curved surfaces, where the emergent light from the first lens coincides with the emergent light from the second lens, with features like flanges, concavo-convex structures, and varying curvature radii to ensure consistent light distribution, and integrated with a light source module within a housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one lens is provided for each light source, then each light source can be covered, but manufacturing deviations cause inconsistent light distribution effects
Solution Approach 1:
Multiple lenses are integrated into a single lens assembly with a shared optical axis. The lens assembly includes a first lens for the first light source and a second lens for the second light source, both aligned to the same optical axis, enabling consistent light distribution across multiple light sources while reducing the impact of individual lens manufacturing deviations.
2Adaptability or versatility
If multiple separate lenses are used for multiple light sources, then each light source is covered, but the device complexity increases
Solution Approach 1:
The lens assembly is designed as a universal optical component that can accommodate multiple light sources with different types (e.g., LEDs, lasers) and configurations. The shared optical axis and standardized mounting structure allow the same lens assembly to work with various light source combinations, reducing the need for multiple specialized lens designs.
3Illumination intensity
If lenses are provided for different light sources respectively, then light coverage is achieved, but illumination effect is affected due to process deviation
Solution Approach 1:
The lens assembly incorporates different lens elements (first lens and second lens) with optimized local optical properties tailored to their respective light sources. Each lens is specifically designed to match the emission characteristics of its associated light source while maintaining alignment with the shared optical axis, ensuring uniform illumination output.

AI summary
The present disclosure provides a lens combination and an illumination device adopting the lens combination, wherein, the lens combination configured for accommodation at least a first light source and a second light source, includes: a first lens, including a first light incident surface, a first light emergent surface and a first accommodation space located on a side of the first light incident surface and configured for accommodating the first light source; the first light incident surface and the first light emergent surface being of a curved surface shape; and a second lens, including a second light incident surface, a second light emergent surface, and a second accommodation space located on a side of the second light incident surface and configured for accommodating the second light source; the second light incident surface and the second light emergent surface being of a curved surface shape. An emergent light obtained after an incident light emitted by a first light source passes through the first light incident surface and the first light emergent surface and an emergent light obtained after an incident light emitted by the second light source passes through the second light incident surface and the second light emergent surface are consistent in light type The present disclosure solves a problem in the prior art that it is difficult to ensure obtaining a same light distribution effect, after light emitted by different light sources is transmitted through the lenses covering the light sources.
