Abstract

The invention provides an optical device for a vehicle lamp, the vehicle lamp and a motor vehicle. The optical device comprises at least one light source, a light diffusion component and a light guiding component, wherein the light diffusion component is arranged to diffuse light beams emitted by the light source so as to form diffusion light beams; the light guiding component is provided with a light incident face, a reflection guiding face and a main light emitting face, the light incident face and the main light emitting face are located at the two opposite sides of the light guiding component, the reflection guiding face is located at the side face, between the light incident face and the main light emitting face, of the light guiding component, wherein the light incident face is configured to receive the diffused light beams, the reflection guiding face is configured to perform at least one-time reflection on the light beams incident from the light incident face so as to guide thereflected light beams to the main light emitting face, and the main light emitting face is configured to output the light beams reflected by the reflection guiding face to the exterior of the light guiding component.

Description

technical field [0001] The invention relates to an optical device for a vehicle light, a vehicle light and a motor vehicle. Background technique [0002] With the development of technology and the progress of society, people's requirements for optical lighting or signal indicating equipment are no longer limited to the function of providing lighting or signal indicator lights. Consequently, there is an increasing demand for the individualization of optical lighting or signaling devices, such as lights for motor vehicles. For the designers of car lights, it is necessary to meet mandatory specifications (such as the lighting range and intensity of different types of car lights stipulated by traffic rules), and to meet the shape and space requirements of car design. Users provide customized lighting effects. This complicates the optical structure of the lamp. For narrow and long car lights, the light beam is often directly introduced into the slender light guide to realize t...
