Vehicular Lamp Side Light Flow Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicular lamps uniformly project light toward the side of a vehicle, resulting in a lackluster appearance when light is emitted in a linear, streamlined fashion, failing to create an aesthetically pleasing effect.
Innovation Solution
A vehicular lamp design featuring a light source, a first reflector with a concavely curved surface, a second reflector with convexly curved and periodically arranged reflection cuts, and inner and outer lenses that diffuse and condense light to produce a flow of light emitted linearly toward the side of the vehicle, enhancing the appearance by varying luminance and depth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light is uniformly projected toward the side of the vehicle, then the lighting function is fulfilled, but the appearance lacks aesthetic appeal and does not produce a streamlined light emission effect
Solution Approach 1:
The reflector is divided into multiple reflective faces arranged along an arc, and the lens is divided into multiple light-emitting regions with different transmission characteristics. This segmentation allows different portions of light to be directed and modified independently, creating both uniform overall illumination and localized streamlined light patterns that enhance appearance.
Solution Approach 2:
Different regions of the lens have different optical properties - some regions transmit light directly while others diffuse light. The reflector also has different reflective faces with varying orientations. This local differentiation enables simultaneous achievement of uniform illumination across the entire lamp and concentrated streamlined light emission in specific directions for aesthetic effect.
2Shape
If a streamlined light emission pattern is created, then aesthetic appearance is improved, but uniform illumination coverage is compromised
Solution Approach 1:
The lens is segmented into multiple light-emitting regions, each responsible for different portions of the light distribution pattern. This allows simultaneous creation of concentrated streamlined light beams for aesthetics and broader uniform illumination coverage by coordinating the output of different segments.
Solution Approach 2:
The single lamp assembly performs multiple functions: it provides uniform side illumination for visibility purposes while simultaneously creating streamlined light emission patterns for aesthetic appeal. The integrated reflector-lens system achieves both functions through coordinated optical design.
3Shape
If complex optical components are added to achieve streamlined light emission, then appearance quality improves, but device complexity increases
Solution Approach 1:
The reflector and lens are integrated into a single coordinated optical system rather than separate adjustable components. The reflector's curved surface with multiple reflective faces is precisely shaped to work in conjunction with the lens's multiple light-emitting regions, achieving complex light patterns through the merged system's geometry rather than through complex mechanical or electronic control.

AI summary
A vehicular lamp capable of producing a flow of light by light emitted toward the side of a vehicle and capable of emitting light with good appearance is provided. The vehicle light includes: a light source (2), a reflector (4) configured to reflect the light emitted from the light source (2) toward a side of the vehicle, and an inner lens (5) configured to allow the light reflected by the reflector (4) to be projected toward the side of the vehicle. The reflector (4) has a reflecting surface (4a) on which a plurality of reflection cuts are periodically arranged in a front-rear direction of the reflector (4). The inner lens (5) has a lens surface (5a) protruded from a surface facing the reflector (4) so as to face the reflecting surface (4a). The lens surface (5a) has a shape extending in the front-rear direction while being curved convexly in a vertical direction, and a radius of curvature of the lens surface (5a) in the vertical direction gradually increases from a proximal end side to a distal end side of the lens surface (5a).
