Title: METHOD FOR THE TREATMENT OF A TRANSPARENT LENS FOR A MOTOR VEHICLE LIGHTING AND/OR SIGNALLING DEVICE
Abstract:
The invention relates to a method (MTH) for the treatment of a transparent lens (G) for a lighting and/or signalling device (P) for a motor vehicle (V), in order to perform a de-icing function (Ft1) and/or an anti-condensation function (Ft2) on the lens (G). The treatment method (MTH) comprises: the deposition of an electrically conductive coating (R) on at least one internal face (s1) of the lens (G), said coating comprising an electrically conductive organic material; and the polymerisation of the coating (R). The invention also relates to a lighting and/or signalling device (P) for a motor vehicle (V), comprising a lens treated using the method of the invention.
