Vehicle Lamp Lens Layers for Patterned Light and Color Reflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lamps struggle to provide a distinct aesthetic differentiation through light emission, as modifying the shape of emitted light is a mature technology and does not sufficiently differentiate vehicles from others.
Innovation Solution
A vehicle lamp design that reflects ambient light in a predetermined color and emits light in a predetermined pattern using internal light sources, incorporating a lens with a color layer and functional layer to achieve this effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a conventional lamp module is used for illumination and signaling, then the basic lighting function is achieved, but the aesthetic differentiation and brand recognition are insufficient
Solution Approach 1:
The lamp assembly is divided into distinct functional zones: a first region with a first light emitter for illumination, and a second region with a second light emitter for signaling. This segmentation allows each region to serve its specific function while contributing to the overall aesthetic pattern, resolving the contradiction between functional adequacy and aesthetic differentiation.
Solution Approach 2:
Different regions of the lamp assembly are assigned different light emission characteristics and functions. The first region provides broad illumination with a specific color temperature, while the second region provides targeted signaling lights. This local differentiation enables both functional performance and aesthetic distinction simultaneously.
2Adaptability or versatility
If the light emission shape is modified to improve aesthetics, then brand recognition is enhanced, but the technology becomes mature and easy to copy
Solution Approach 1:
The lamp assembly performs multiple functions within a unified design: illumination, signaling, and aesthetic branding. The coordinated operation of the first and second light emitters creates a multi-functional system that is difficult to copy, as it requires integrating both functional and aesthetic elements rather than simply modifying light shape.
Solution Approach 2:
The lamp assembly employs dynamic control of light emission patterns, colors, and intensities across different regions. The controller can vary the operation of the first and second light emitters to create different modes (e.g., normal operation, warning, turning), making the system adaptable and difficult to replicate through static design modifications alone.
3Adaptability or versatility
If a dual-region lamp assembly with coordinated light emitters is used, then aesthetic differentiation and brand recognition are significantly enhanced, but the device complexity increases
Solution Approach 1:
The first and second light emitters are integrated into a single lamp assembly housing with a unified lens structure. The controller that manages both light emitters is consolidated within the same assembly, reducing the need for separate control systems and simplifying the overall device architecture despite the increased functional capabilities.
Solution Approach 2:
The single controller manages multiple functions (illumination control, signaling control, color temperature adjustment) through a unified control architecture. This universal controller reduces the need for multiple separate control devices, offsetting the complexity introduced by having multiple light emitters and functional regions.

AI summary
A vehicle lamp, which reflects light of a predetermined color using ambient light and emits light of a predetermined pattern using internal light, includes: a light source that emits light; a lens disposed in a light emission path of the light source; and a main film attached to the lens. The main film includes: a color layer that reflects ambient light in a predetermined color; and a functional layer that selectively transmits the light emitted from the light source.
