Problems solved by technology

[0002] With the continuous development of modern automobiles towards electrification, intelligence, networking, and sharing, more and more automobiles have begun to apply a large number of new technologies, and the functions of automobile lamps are becoming more and more abundant, and relevant regulations are also being continuously improved. , In the regulatory meeting held in November 2020, the discussion and research on the regulations on the external projection system of the car were formally discussed. The existing projection system for the vehicle mainly focuses on the door panel lights, rearview mirror lights and other vehicles that can be vertical to the ground when the door is opened. Projecting the brand logo cannot meet the needs of road indication when the vehicle is driving

Abstract

The invention discloses a vehicle projection lighting system for road indication, and the system is sequentially provided with a first lens with positive focal power, a film sheet, wherein a modulated pattern is carved on the film sheet; a second lens having positive focal power, wherein two surfaces of the second lens are convex surfaces; a third lens having negative focal power, wherein two surfaces of the third lens are concave surfaces; and a fourth lens having positive focal power, wherein two surfaces of the fourth lens are convex surfaces in sequence from a light source side to an imaging side along the optical axis. The required lamplight patterns can be projected on the ground around a vehicle body, attention of pedestrians can be attracted by matching with a vehicle lamp system, driving safety is improved, and the system has important significance on development of the vehicle lamp industry.

Description

technical field [0001] The invention relates to the technical field of vehicle lights, in particular to a vehicle projection light system for road surface indication. Background technique [0002] With the continuous development of modern automobiles towards electrification, intelligence, networking, and sharing, more and more automobiles have begun to apply a large number of new technologies, and the functions of automobile lamps are becoming more and more abundant, and relevant regulations are also being continuously improved. , In the regulatory meeting held in November 2020, the discussion and research on the regulations on the external projection system of the car were formally discussed. The existing projection system for the vehicle mainly focuses on the door panel lights, rearview mirror lights and other vehicles that can be vertical to the ground when the door is opened. Projection of the brand logo cannot be used for road indication when the vehicle is driving. ...
