The invention relates to a lighting device () including a lighting source () and a light guide (), the light guide including an inlet optical surface (), configured to allow the entry of the light emitted by the light source illuminating the inlet optical surface, and an outlet optical surface (), configured to allow the exit of the light from the light guide, characterized in that the light guide also includes at least two through-holes () arranged passing through the inlet optical surface and the outlet optical surface.

Lighting device

The lighting device includes at least two light sources; at least two input guides coupled to the light sources; and a light collector coupled to the light-sensing guides. Each of the input guides has an input end facing the corresponding light source, and an output end tangentially coupled to the light collector such as to lead a light beam from the corresponding light source into the collector. The input guides are helically-shaped between the input and the output ends.

The invention relates to a method for manufacturing an interface module (), the interface module () including a display member () that is to be visible through a transparent slab (S), characterized in that it comprises the steps of: silk-screening an opaque ink () onto certain areas of a film () so as to define frames or symbols; depositing adhesive (C) between the film () on the silk-screened ink () side, and the transparent slab (S) of the interface module (); and adhering, and laminating the film () onto the transparent slab (S) of the interface module (). The invention also relates to the associated interface module produced according to said method.
