Vehicle Lamp Lens Pattern for 3D Lighting With Fewer Components

Solution Overview

Problem

Conventional vehicle lamps that implement three-dimensional lighting images require separate light sources and media, such as lenses or films, increasing manufacturing costs and component counts, which hinders product value enhancement and cost reduction.

Innovation Solution

A vehicle lamp design that incorporates a light source and a lens part with a three-dimensional pattern, where the light is output to create a three-dimensional image without a separate special light source, lens, or film, utilizing total reflection principles and varying pattern designs on the lens surfaces to achieve a 3D effect.

Engineering Contradictions & Design Principles

1Shape

If conventional three-dimensional lighting image technologies (lenticular lens, hologram, optical fiber) are used, then a three-dimensional lighting image can be implemented, but manufacturing costs and the number of components increase

Engineering Contradiction:

Improvethree-dimensional lighting imageVSAvoidnumber of components

Core Design Contradiction:

ShapeVSDevice complexity

Solution Approach 1:

The patent merges the light source and the three-dimensional pattern into a single integrated lamp body structure. The light source is positioned at the rear of the lamp body, and the three-dimensional pattern is formed on the front surface of the same lamp body, eliminating the need for separate lenses, films, or additional optical components that were required in conventional technologies.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The lamp body serves multiple functions: it acts as both the housing structure and the optical element that creates the three-dimensional effect. The front surface of the lamp body itself is used to form the three-dimensional pattern, eliminating the need for separate optical components and reducing overall device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Disclosed is a lamp for a vehicle. The lamp for a vehicle includes a light source part, and a lens part that outputs light input from the light source part to a front side, and having a three-dimensional pattern having a specific pattern shape, the lens part outputs the light input from the light source part to the front side when the light reaches the three-dimensional pattern, and the three-dimensional pattern is patterned such that a lighting image generated by the light output to the front side of the lens part is implemented as a three-dimensional image.
