Side-Incident Vehicle Light Optical Element for Narrow Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle light optical elements fail to meet the requirements of smaller front-rear and up-down sizes while maintaining a larger left-right size, hindering the development of narrow and long vehicle lights.
Innovation Solution
A vehicle light optical element design featuring light-incident portions on the sides of a light-emergent face, with a reflecting face that reflects light rays to the light-emergent face, and an integrated lens part to simplify structure and enhance stability, allowing for a smaller front-rear and up-down size with a larger left-right size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a common concentrator structure is used with light inlet at rear end and light outlet at front end, then light transmission function is achieved, but the front-rear size becomes longer
Solution Approach 1:
The patent repositions the light incident portion from the rear end to the side of the light emergent face, changing the spatial arrangement from a linear front-rear configuration to a side-incident configuration. This dimensional change allows the light source and radiator structure to be arranged laterally rather than longitudinally, thereby reducing the front-rear size while maintaining light transmission functionality.
2Length of moving object
If a bending type concentrator is used with light inlet at lower end, then the front-rear size is reduced, but the up-down size becomes larger due to vertical concentrating cup arrangement
Solution Approach 1:
The patent positions the light incident portion on the side of the light emergent face rather than at the lower end, and arranges the light source and radiator structure laterally. This shifts the spatial configuration from a vertical arrangement (increasing up-down size) to a lateral arrangement, thereby reducing both the front-rear size and the up-down size while maintaining the larger left-right size.
3Length of moving object
If light source and radiator structure are arranged behind the light inlet, then light transmission is achieved, but the front-rear size is increased
Solution Approach 1:
The patent repositions the light incident portion to the side of the light emergent face, allowing the light source and radiator structure to be arranged laterally rather than behind the light inlet. This spatial reconfiguration reduces the front-rear size while maintaining effective light transmission through the optical element.
4Length of stationary object
If light source and radiator structure are arranged below the light inlet, then light transmission is achieved, but the up-down size is increased
Solution Approach 1:
The patent positions the light incident portion on the side of the light emergent face and arranges the light source and radiator structure laterally, shifting from a vertical arrangement below the light inlet to a lateral arrangement. This reduces the up-down size while maintaining effective light transmission.
5Shape
If the vehicle light shape becomes narrower and longer with smaller up-down size and larger left-right size, then the modeling trend is achieved, but the front-rear size cannot be reduced further
Solution Approach 1:
The patent repositions the light incident portion to the side of the light emergent face and arranges the light source and radiator structure laterally, enabling the vehicle light to achieve the desired narrow and long shape with smaller front-rear size and up-down size, and larger left-right size, consistent with current modeling trends.
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 design reduces the front-rear and up-down sizes of the vehicle light optical element, aligning with current vehicle light modeling trends, improves light intensity, and simplifies the structure by integrating the lens part, enhancing stability and functionality.
Implementation Method 1
the reflecting face is configured to be able to reflect light rays, which are emitted from the light-incident portion into the reflecting face, to the light-emergent face

AI summary
A vehicle light optical element, a vehicle light module, and a vehicle light. The vehicle light optical element comprises light-incident portions, a light-emergent face and a reflecting face, wherein the light-incident portions are arranged on a side of the light-emergent face; and the reflecting face is configured to be able to reflect light rays, which are emitted from the light-incident portions into the reflecting face, to the light-emergent face, so as to be emitted out of the light-emergent face. The vehicle light optical element has the characteristics of a smaller front-rear size, a smaller up-down size, and larger left-right size, and can better adapt to the current vehicle light shape trend.
