LiFi-and-DLP-based automotive illumination system and vehicle illumination signal device hereof

Abstract

The invention relates to function features or parts of a vehicle illumination signal device or system, provides an LiFi-and-DLP-based automotive illumination system and a vehicle illumination signal device hereof. An LED main light source is used as a sending light source of a light fidelity (LiFi) sending assembly to send driving data of a vehicle out. A built-in LiFi receiving assembly is used for receiving a light signal sent by an opposite-side vehicle; decoding is carried out to obtain driving data of the opposite-side vehicle; and the data are transmitted to a vehicle bus. A digital light processing (DLP) projection system based on a DMD chip is used for providing projection illumination; according to the driving data, obtained by the LiFi receiving assembly, of the opposite-side vehicle, a projection illumination area is controlled; and a phenomenon that driving security is affected by dazzling light caused by a headlamp can be avoided by adjusting a projection area of light projected to an opposite-side driver position, so that information interaction between vehicles in a vehicle light signal reaching range is realized. A driving state of an adjacent vehicle is estimated and thus early warning of a vehicle collision accident is realized, thereby reducing the probability of a traffic accident effectively.

Description

technical field [0001] The present invention relates to the functional features or components of a vehicle lighting signal device or its system, in particular to a car headlight that uses LiFi and DLP to change the characteristics and distribution of light emission from the car light. Background technique [0002] With the continuous improvement of automobile production capacity and people's living standards, automobiles have increasingly become the means of transportation for ordinary families. However, with the continuous improvement of automobile utilization rate, the incidence of traffic accidents is also rising. Therefore, in recent years, many domestic research institutions have begun to devote themselves to the research of automotive active safety technology. When a car is driving, in order to prevent accidents, it is necessary not only to drive safely, but also to observe and understand the driving conditions of the surrounding cars in time so as to take timely measu...
