Vertical Headlamp Lens Layout for Uniform Road Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of vertical headlamp modules on automotive vehicles often results in decreased lighting performance, including non-optimal uniformity and intensity, which is a concern for manufacturers seeking an aesthetic upgrade.
Innovation Solution
Designing a vertical headlamp module with lenses taller than wide, allowing for stacked lighting units that maintain lighting performance through adaptable lighting functions and focal point adjustments, even when inclined.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If vertical headlamp modules are installed to achieve aesthetic appearance, then visual appearance is improved, but lighting performance deteriorates
Solution Approach 1:
The headlamp module is divided into multiple separate lighting units (first lighting unit, second lighting unit, etc.), each with its own lens and light exit area. This segmentation allows each unit to be optimized for specific lighting functions while collectively achieving the desired vertical aesthetic appearance. Each lighting unit can be independently configured to contribute to overall lighting performance.
Solution Approach 2:
The patent transitions from conventional horizontal headlamp modules to a vertical configuration by arranging lighting units stacked above one another in the vertical dimension. This dimensional change achieves the desired aesthetic appearance while maintaining lighting performance through proper optical design of each vertical unit.
2Shape
If vertical headlamp modules are installed, then aesthetic appearance is improved, but uniformity of lighting deteriorates
Solution Approach 1:
Each lighting unit is designed with specific local characteristics - different lenses (10, 26) with different optical properties, different light exit areas, and different arrangements of light elements. This local quality differentiation allows each unit to contribute specifically to achieving uniform lighting across the entire vertical module while maintaining the aesthetic vertical appearance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures equivalent lighting performance to conventional units, offering customizable lighting effects and maintaining uniformity and intensity while achieving a desired aesthetic appearance.
Implementation Method 1
Each lighting unit comprises at least one lens (10, 26), the lens being disposed in the lighting unit such a way that a height of the lens is greater than a width of the lens
