Solution Overview
Problem
Existing vehicle light systems fail to provide effective illumination in areas surrounding the vehicle, particularly on the exterior, where traditional lighting solutions are limited by location and exposure to debris and obstacles.
Innovation Solution
A light system is integrated into the vehicle's bumper assembly, featuring a light source coupled with a lens that directs excitation light to an airflow control device, which includes a luminescent structure that converts the light into a longer wavelength, providing sustained illumination even after the excitation source is removed, and can be activated by a controller for enhanced visibility and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional lighting solutions are used on the vehicle exterior, then the lighting can be simple in structure, but the illumination effectiveness is limited and the lighting is vulnerable to debris and obstacles
Solution Approach 1:
The patent uses an airflow control device as an intermediary carrier to hold and display luminescent structures. This intermediary approach allows the light-emitting components to be positioned in locations that were previously difficult to illuminate, while the airflow control device itself serves as a protective platform that reduces direct exposure to debris and obstacles.
Solution Approach 2:
The patent extends illumination to previously unlit areas by utilizing the airflow control device's surface as a new dimensional platform. By placing luminescent structures on the airflow control device, the system achieves illumination in three-dimensional space around the vehicle, particularly in areas below and around the bumper assembly that were previously dark zones.
2Duration of action of moving object
If traditional lighting systems are installed on the bumper assembly, then the structure remains simple, but the ability to provide sustained illumination without continuous power is lost
Solution Approach 1:
The luminescent structures are pre-charged with energy through exposure to excitation light before they are needed for illumination. This preliminary energy storage in the luminescent materials allows them to emit light for extended periods without requiring a continuous power source during the actual illumination phase.
Solution Approach 2:
The luminescent structures serve themselves by converting absorbed light energy into sustained light emission without requiring external power during operation. The system uses the excitation light source as a charging mechanism, after which the luminescent materials independently provide prolonged illumination, effectively serving their own energy needs.
