Solution Overview
Problem
Conventional vehicle lamps have a simple function and dull appearance, lacking uniqueness and value, necessitating an innovative structure to enhance their functionality and aesthetic appeal.
Innovation Solution
A transparent vehicle lamp design featuring two lenses with a reflecting surface and light emitting members, where light beams are reflected along an optical axis to create a unique light output pattern, allowing for both forward and rearward signaling while showcasing scenery images, utilizing Total Internal Reflection theory to optimize light utilization and diffusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a conventional vehicle lamp structure is used, then the lamp can perform basic lighting and signaling functions, but the appearance is dull and lacks uniqueness
Solution Approach 1:
The transparent lens is designed to perform multiple functions simultaneously: it transmits light for signaling, reflects light for illumination, and forms images of scenery for aesthetic purposes. This multi-functionality allows the lamp to maintain basic lighting and signaling functions while adding unique visual characteristics through the transparent design that showcases internal structures and reflected images.
2Shape
If a transparent lens design is used to enhance appearance, then uniqueness is improved, but light transmission and distribution may be compromised
Solution Approach 1:
The lens is divided into distinct functional zones: a transparent main body for aesthetic purposes, a light incident surface for light entry, a light output surface for light transmission, and an integrated reflecting surface for light redirection. This segmentation allows each zone to optimize its specific function while maintaining the overall transparent appearance that provides uniqueness.
Solution Approach 2:
Different regions of the lens have different optical properties tailored to their specific functions. The light incident surface is optimized for light entry, the reflecting surface for light redirection, and the light output surface for light transmission. This local optimization ensures that light transmission and distribution are not compromised despite the transparent design.
3Illumination intensity
If multiple light emitting members and reflecting surfaces are added to improve light distribution, then illumination quality is enhanced, but device complexity increases
Solution Approach 1:
The reflecting surface is integrated directly into the lens structure rather than being a separate component. This merging of the reflecting function into the transparent lens body allows for enhanced light distribution and illumination quality while avoiding the complexity of additional separate reflecting components, mounting structures, and alignment mechanisms.

AI summary
A transparent vehicle lamp includes at least one lens (1) having a main body portion (11) and a first light input portion (12). An optical axis (L) extends through the main body portion (11) in a front-rear direction. The main body portion (11) has a reflecting surface (111) intersecting with the optical axis (L), a coupling surface (112) connected to a periphery of the reflecting surface (111) and a light output surface (113) spaced apart from the reflecting surface (111) and the coupling surface (112) along the optical axis (L) such that the image of a scenery toward which the coupling surface (112) faces is formed on the light output surface (113).
