DEVICE FOR ACTUATING AN OPTICAL ELEMENT OF AN ILLUMINATING AND/OR SIGNALING DEVICE

摘要

Device for actuating at least one optical element of an illuminating and/or signaling device of an automobile, comprising an actuation element arranged so as to displace the optical element under the effect of the energy of rays of the sun, wherein the actuation element comprises an expansible element which deforms under the effect of heat and which is thermally coupled to the optical element, in order to displace the latter when it experiences heating due to the rays of the sun, in order to prevent it from being damaged by the rays of the sun.
