Vehicle Lamp Three-Dimensional Lighting via Segmented Light Sources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rear combination lamps lack three-dimensional lighting, relying primarily on surface light sources for luminance, which limits their ability to provide effective illumination and visibility.
Innovation Solution
A vehicle lamp design incorporating at least two different light sources with a light guide, where one light source is positioned on a substrate with a diffuser and lenses, and the other with a reflective part and a light guide formed in a polygonal shape, allowing for enhanced three-dimensional lighting by diffusing and reflecting light in various directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional rear combination lamp uses a surface light source with a light guide panel, then efficient light transmission and luminance are achieved, but three-dimensional lighting cannot be provided
Solution Approach 1:
The lamp is divided into multiple independent light sources (first light source and second light source) positioned at different locations and orientations. Each light source has its own light guide structure, allowing separate control and directional illumination, thereby achieving three-dimensional lighting effects while maintaining efficient luminance from each segment
Solution Approach 2:
The patent transitions from a conventional single-plane surface light source to a multi-dimensional lighting system by positioning light sources at different heights and angles relative to the light guide panel. The first light source is positioned above the panel while the second light source is positioned at an angle, creating illumination from multiple spatial dimensions rather than a single surface plane
2Illumination intensity
If multiple light sources are added to provide three-dimensional lighting, then lighting effectiveness is improved, but device complexity increases
Solution Approach 1:
Multiple light sources and their associated light guide structures are merged into a single integrated lamp housing assembly. The first and second light sources share a common mounting structure and coordinate system, with their light guide panels forming a unified optical system that reduces overall structural complexity compared to separate lighting units
Solution Approach 2:
The light guide panel serves multiple functions simultaneously: it acts as a diffuser for the first light source, a reflective surface for the second light source, and a structural element of the lamp assembly. This multi-functionality reduces the need for additional separate components, thereby managing device complexity while achieving three-dimensional lighting

AI summary
The present invention relates to a lamp and a vehicle having the same, the lamp including: a housing; a substrate arranged on the housing; a first light source and a second light source arranged on one side surface and the other side surface of the substrate, respectively; and a light guide arranged on a path of light emitted from the second light source. Accordingly, the lamp can both realize stereoscopic lighting and improve the design-related degree of freedom when installed on a vehicle.
