A car lighting system based on lifi and dlp and its vehicle lighting signal device

Abstract

A LiFi and DLP-based automotive lighting system and its vehicle lighting signal device, related to the vehicle lighting signal device or its system's functional characteristics or parts, using LED main light source as the sending light source of the LiFi sending component, and the vehicle's driving data Send it out; receive the optical signal sent by the other vehicle through the built-in LiFi receiving component, decode and process the driving data of the other vehicle and send it to the car bus; use the DLP projection system based on the DMD chip to provide projection lighting, and obtain the light signal according to the LiFi receiving component The driving data of the opponent's vehicle controls the projected lighting area. By adjusting the light projection area projected to the driver's position of the opponent, the glare light generated by the headlights can be prevented from affecting driving safety, and the information exchange between vehicles within the reach of the light signal of the lights can be realized. ; By evaluating the driving state of adjacent vehicles, an early warning is issued for vehicle collision accidents, thereby effectively reducing the probability of traffic accidents.

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...
