AI Technical Summary

Technical Problem

When existing car light devices are curved, the extension direction of the light exit surface is not always perpendicular to the main light exit direction, resulting in reduced light efficiency and visibility being affected at different angles.

Method used

An optical assembly is designed, including a light source, a light guide unit, a backplane and a functional layer. The functional layer deflects and scatters the light from the light guide unit through the deflection layer and the scattering layer, redirects and evenly emits it, thereby adapting to the needs of non-planar light-out surfaces.

Benefits of technology

Improves the light efficiency and visibility of the lighting device, especially when the vehicle shape needs to be bent, ensuring the uniform lighting effect of the light at different angles.

Abstract

The invention relates to an optical assembly comprising: a light source (101) configured to emit light; the light guide unit (102) is configured to receive and guide light rays emitted by the light source (101) and emit the light rays from a light emitting surface of the light guide unit (102); the back plate (103) is configured to provide support for the light guide unit (102); and a functional layer (106), the functional layer (106) being arranged on a light emitting side of the light guide unit (102) so as to deflect and scatter light from the light guide unit (102). The invention further provides a lighting and / or signal indicating device and a vehicle.
