Solution Overview
Problem
The challenge is to design a vehicle lamp apparatus that reduces the size of the optical system while maintaining light efficiency, as current systems face difficulties in minimizing size without compromising light output.
Innovation Solution
A slim type lamp apparatus featuring a light source and a lens portion with specific reflective surfaces that diffuse and condense light to form distinct beam patterns, allowing for reduced optical system size while maintaining light intensity, and optionally includes an extra light source and lens portion for enhanced light distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the optical system size is reduced, then the package configuration is improved, but the light amount may be compromised
Solution Approach 1:
The lens portion is divided into three distinct functional portions: an incident portion for receiving light, a reflection portion for reflecting and directing light, and an emission portion for emitting the reflected light. This segmentation allows each portion to be optimized for its specific function, enabling compact overall design while maintaining effective light control and output.
Solution Approach 2:
Different portions of the lens have different internal widths optimized for their specific functions. The incident portion and emission portion have greater internal widths than the reflection portion, allowing adequate space for light reception and emission while minimizing the overall optical system size. This local optimization of dimensions maintains light efficiency while achieving compact packaging.
2Volume of moving object
If the lens portion width is minimized, then the optical system becomes more compact, but light distribution control becomes difficult
Solution Approach 1:
The reflection portion is divided into multiple reflection surfaces (first, second, and third reflection surfaces) that work together to control light distribution. This segmentation of the reflective function allows precise control over light paths and beam patterns within a compact space, maintaining adaptability for different lighting requirements.
Solution Approach 2:
The patent controls light distribution not just through horizontal width but also through vertical arrangement of multiple reflection surfaces at different positions. The first reflection surface reflects light to a focus, the second reflection surface directs light toward the emission portion, and the third reflection surface adjusts the beam pattern. This multi-dimensional arrangement enables effective light control within a compact footprint.

AI summary
A slim type lamp apparatus of a vehicle may include a light source for radiating light; and a lens portion including an incident portion through which the light radiated by the light source is incident, a reflection portion extending from the incident portion to reflect and move the incident light, and an emission portion extending from the reflection portion and emitting the light reflected by the reflection portion, the reflection portion diffusing some light upon reflection of the light to form a diffusion beam pattern by the emission portion and condensing other light upon reflection to form a condensing beam pattern by the emission portion.
