A lighting device for a motor vehicle is provided with numerous light sources, at least one optical component in the form of a microstructured film and/or microstructured optical panel, and a collecting and/or focusing lens. The lighting device is configured such that the light from the light sources passes through the collecting and/or focusing lens before passing through the at least one optical component.

An illuminated emblem for vehicles comprising a container body delimiting a cavity, a lighting device comprising at least one lighting source, at least partially housed in said cavity and configured to emit at least one light beam, an inner lens to cover at least partially said lighting source, the inner lens comprising a first transparent layer and a second diffusing or opalescent layer, said first transparent layer and second diffusing or opalescent layer being mutually integral. The container body comprises at least one protrusion which at least partially crosses the cavity and abuts against a fixing portion of the inner lens with which it forms a laser welding joint, said fixing portion being in contact with the first transparent layer or with the second diffusing or opalescent layer, an outer lens superimposed to cover at least partially the inner lens and to close at least partially the cavity.

Lighting element in particular for an automobile, comprising a mixing box comprising a backwall and sidewalls extending from the backwall, at least one light emitting element, extending through an opening of the backwall, and a diffusor connected to the mixing box opposite to the backwall and having a front face facing away from the backwall and an opposite back face facing in the direction of the backwall, wherein the diffusor receives light from the at least one light emitting element via its back face and emits light via its front face, wherein the back face of the diffusor extends towards the backwall of the mixing box, wherein the extension of the back face is asymmetrical along at least one lateral direction and the back face is distant of the backwall.

A light guide comprises a center body portion that extends along a center axis and which has a first end associated with a light source and an opposite second end associated with a plurality of non-coplanar surfaces. A first leg portion extends away from the center body portion in a first direction and a second leg portion extends away from the center body portion in a second direction opposite of the first direction.
