V-Shaped Lens for Wide-Angle Uniform Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lenses used in lighting devices often limit the angle of emergent light and fail to achieve uniformity, resulting in inadequate wide-angle and uniform light distribution.
Innovation Solution
The lens design incorporates a collimation plus total reflection structure and a dual curved surface structure, with a first light-incident surface and two second light-incident surfaces that are opposite and curved, and outer surfaces featuring intersecting reflective and exiting surfaces forming a V-shaped structure, to achieve wide-angle and uniform light distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional lens structures are used, then the lens is simple in structure, but the angle of emergent light is limited and uniformity is poor
Solution Approach 1:
The lens is divided into multiple functional regions: a first light-incident surface for receiving light, two second light-incident surfaces adjacent to the first, first reflective surfaces forming a V-shaped structure, and multiple light-exiting surfaces. Each region performs a specific optical function to collectively achieve wide-angle and uniform light distribution, resolving the contradiction by segmenting the lens into specialized zones rather than using a simple uniform structure.
Solution Approach 2:
The patent employs curved surfaces throughout the lens structure, including the first light-incident surface, the two second light-incident surfaces, and the light-exiting surfaces. These curved geometries are specifically designed to control light paths, achieve collimation effects, and distribute light uniformly across wide angles, directly addressing the uniformity issue while maintaining structural integrity.
2Illumination intensity
If conventional lens structures are used, then the lens is simple in structure, but the coverage angle of emergent light is small
Solution Approach 1:
The lens is divided into multiple functional regions: a first light-incident surface for receiving light, two second light-incident surfaces adjacent to the first, first reflective surfaces forming a V-shaped structure, and multiple light-exiting surfaces. Each region performs a specific optical function to collectively achieve wide-angle and uniform light distribution, resolving the contradiction by segmenting the lens into specialized zones rather than using a simple uniform structure.
Solution Approach 2:
The patent introduces a V-shaped reflective structure formed by intersecting first reflective surfaces, adding a dimensional element that redirects light at wider angles. This three-dimensional reflective geometry enables light to emerge over a broader angular range by utilizing spatial redirection in multiple dimensions, thereby expanding the coverage angle beyond what conventional planar lenses achieve.
3Illumination intensity
If more lenses are used to achieve wider coverage and better uniformity, then the lighting effect is improved, but the cost increases
Solution Approach 1:
The lens integrates multiple functions within a single component: it receives light from the light-emitting component, performs collimation through curved incident surfaces, redirects light at wide angles via V-shaped reflective surfaces, and distributes light uniformly through multiple light-exiting surfaces. This multi-functional design replaces what would traditionally require multiple separate optical elements, reducing the quantity of lenses needed while maintaining or improving light distribution quality.
Solution Approach 2:
The patent combines collimation, reflection, and light distribution functions into a single integrated lens structure. The first and second light-incident surfaces work together with the V-shaped reflective surfaces and multiple light-exiting surfaces to achieve wide-angle uniform illumination in one component, merging functions that would traditionally require separate optical elements and thereby reducing the total number of lenses required.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enables the lens to produce emergent light with a wide coverage angle and high uniformity, effectively illuminating larger areas with fewer lenses, thereby reducing costs and improving lighting fixture efficiency.
Implementation Method 1
the outer surface may include two first reflective surfaces, two first light-exiting surfaces, and two second light-exiting surfaces; the two first reflective surfaces may be located in a middle top region and are intersected with each other
Implementation Method 2
each of the two second light-incident surfaces may be a curved surface protruding toward a direction away from the first receiving chamber
