Solution Overview
Problem
Conventional vehicle lamps with light guides are limited to two-dimensional light emission and struggle to implement three-dimensional light emission images effectively.
Innovation Solution
A lamp design that incorporates a light guide part with a reflective surface and a 3-dimensional light forming pattern, allowing light to be reflected in additional directions beyond the forward direction, utilizing a plurality of reflective optics and unit optical patterns to create a three-dimensional light emission effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a conventional light guide uses a cut formed in a rearward direction to guide light, then light is guided in the forward direction, but only two-dimensional light emission images can be implemented
Solution Approach 1:
The patent introduces a 3-dimensional light forming pattern with inclined guide surfaces that reflect light in multiple directions (forward, upward, downward) rather than only in the forward direction. This adds vertical dimensionality to the light emission, transforming 2D light emission images into 3D light emission images with enhanced depth perception and aesthetic effect.
Solution Approach 2:
The light guide structure is segmented into multiple functional regions: a reflective surface for forward light guidance and a 3-dimensional light forming pattern with multiple inclined guide surfaces for multi-directional light reflection. Each segment performs a specific light directing function, collectively achieving complex 3D light emission effects.
2Adaptability or versatility
If a light guide guides most light only in the forward direction, then the lighting function is maintained, but design flexibility for various light emission images is limited
Solution Approach 1:
Different regions of the light guide are assigned different optical functions: the reflective surface maintains strong forward light guidance for primary illumination, while the 3-dimensional light forming pattern with inclined surfaces creates additional upward and downward light emission for design versatility. Each local region optimizes its light emission characteristics to fulfill specific functional requirements.
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 enables the implementation of three-dimensional light emission images, enhancing aesthetic appeal and design flexibility without compromising the primary lighting function.
Implementation Method 1
a reflective surface configured to reflect the light input to the guide body in a forward direction being an output direction
Implementation Method 2
the 3-dimensional light forming pattern is formed to reflect the light input to the guide body in a different direction from a direction of the light reflected by the reflective surface

AI summary
A lamp for a vehicle is provided. The lamp includes: a light source part; and a light guide part to guide the light input from the light source part and output the light. The light guide part includes: a guide body, to which the light irradiated from the light source part is input; an input surface, to which the light provided on one side of the guide body is input; a reflective surface to reflect the light in a forward direction; an output surface being a surface of an outer surface of the guide body, except for the input surface and the reflective surface, and being a surface to output the light; and a 3-dimensional light forming pattern formed in the guide body, and reflecting the light input to the guide body in a different direction from a direction of the light reflected by the reflective surface.
