Vehicle lamp optical unit, vehicle lamp module and vehicle

Abstract

The invention relates to a vehicle lighting device, and discloses a vehicle lamp optical unit, a vehicle lamp module and a vehicle. The automobile lamp optical unit comprises a first optical element, the rear end face and the front end face of the first optical element in the light emitting direction are a light-in structure datum plane and a first light outlet surface respectively, and a light-in part is formed at the rear end of the first optical element and comprises at least one first light-in structure arranged in the left-right direction of the light-in structure datum plane. A first light channel is formed between the light-in part and the first light outlet surface; wherein the first light-in structure are arranged to extend from the upper side or the lower side of the reference surface of the light-in structure to the first light channel, and each first light-in structure can guide light received by the light-in structure to be emitted towards the first light channel and transmitted to the first light outlet surface along the first light channel. According to the automobile lamp optical unit, the visual effect during automobile lamp illumination can be improved, and the requirements of multiple illumination modes and lightening modes are met.

Description

technical field [0001] The present invention relates to a vehicle lighting device, in particular to a vehicle light optical unit. In addition, it also relates to a vehicle light module and a vehicle. Background technique [0002] With the rapid development of the automobile industry and the continuous improvement of people's living conditions, automobiles have become one of the indispensable means of transportation for people to travel. The number of cars in the world is increasing year by year, and the popularity of cars has also led to the rapid development of the manufacturing and design of auto parts. For example, the role of car lights is not limited to lighting functions, its appearance and the specific light effect mode of turning on or off the lights are beginning to be pursued by consumers. [0003] With the diversification of car lamp shapes and lighting modes, vehicle lighting devices need to be equipped with multiple vehicle lighting units, such as low beam, hi...

AI Technical Summary

Problems solved by technology

However, multiple vehicle lighting units are scattered and installed independently, which will not only cause the entire vehicle lighting device to take up a lot of space, increase the volume of the car lights, but also increase the positioning and installation errors between components, affecting the accuracy of the optical system

In addition, the light source of the vehicle lighting unit is usually arranged behind the light incident part, which will form light spots when the lights are turned on, which will affect the appearance of the lights when the lights are turned on
