Vehicle Lighting Apparatus with Selective Light Diffusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle lighting apparatuses primarily focus light towards the front, limiting design flexibility and aesthetic enhancement, especially in restricted spaces like headlamps and rear lamps, where diffused light irradiation into surrounding areas is not effectively achieved.
Innovation Solution
A lighting apparatus featuring a vehicle body panel with a main and extended lighting area, a light guide that extends from the main to the extended area, and a movable lighting selection mechanism to selectively partition the light emission area, allowing light to be directed either solely to the main area or both areas, using a guide block and driving mechanism to control light distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light is focused toward the front side of the vehicle, then lighting effectiveness for forward illumination is improved, but design flexibility and aesthetic enhancement are limited
Solution Approach 1:
The lighting apparatus is divided into a main lighting area for forward illumination and an extended lighting area for aesthetic enhancement. The light guide is segmented into a main area and an extension area, allowing independent optical control of each zone to achieve both functional lighting and design flexibility
Solution Approach 2:
A movable lighting selection mechanism (guide block) is introduced that can dynamically adjust the light path between different configurations. The guide block can be positioned to direct light to either the main lighting area only, or to both the main and extended lighting areas, providing adaptive design versatility
2Adaptability or versatility
If the light guide extends to the extended lighting area, then design flexibility and aesthetic enhancement are improved, but light distribution control becomes more complex
Solution Approach 1:
A guide block is introduced as an intermediary component between the light source and the extended lighting area. This simple mechanical element controls the complex light distribution by either blocking or allowing light to reach the extension area, simplifying the control mechanism while achieving versatile lighting configurations
3Adaptability or versatility
If a movable lighting selection mechanism is added to control light emission areas, then design flexibility is improved, but device complexity increases
Solution Approach 1:
The guide block is designed with differentiated local properties: a first portion that allows light transmission to the main lighting area and a second portion that can block or redirect light to the extended lighting area. This local quality differentiation enables complex lighting control functions through a relatively simple component structure

Function Achieved in This Case
Enables diffused light irradiation into surrounding areas, enhancing vehicle exterior design by allowing light to be projected from the bumper or grille, while providing design flexibility through selective light emission control.
Implementation Method 1
a light guide provided to allow the light emitted from the light source to be incident thereon, configured to irradiate light due to the incident light

AI summary
A lighting apparatus of a vehicle is provided to allow irradiation of light to be diffused into a surrounding area together with a lighting area in which the light is irradiated. The is irradiated even from a bumper or a grille of the vehicle. In addition, in an area in which the irradiation of the light is diffused in the vehicle in addition to the lighting area, the diffusion of the light is selectively determined.
