Abstract: The object of the invention is an optical module intended to equip a lighting and/or a signaling device for a motor vehicle, the said optical module comprising at least one reflector associated with at least one light source. The said optical module comprises at least one optical element disposed at the front of the light source and able to deviate rays directly emitted by the source and/or emitted by the source and then reflected by the reflector, the deviation of the rays comprising at least one step of total reflection of the said rays in the said optical element.

Abstract: The invention relates to a photovoltaic concentration module and device. The device includes: a primary lens (10) configured to concentrate incident solar radiation and to generate a first concentrated radiation; a solar cell (30) configured to collect the first concentrated radiation; and a substrate (40) enabling the electrical connection and thermal dissipation of the solar cell, whereby the solar cell (30) and the substrate (40) are electrically associated so as to form an electric power generation unit. The photovoltaic concentration module includes a series of the aforementioned devices.
