  • Patent number: 10267480
    Abstract: A lighting assembly for lighting and/or signaling in a motor vehicle that palliates the disadvantages resulting from the reflection and focusing of solar rays by focusing means of a lighting module for lighting and/or signaling in a motor vehicle onto a mask disposed under a lighting module. The lighting assembly comprises means for emitting and means for focusing one or more light beams, together with a mask, a part of which extends under the focusing means. A part of the mask is transparent to light, so that solar rays reflected and focused by the focusing means onto the mask pass through the transparent part.

  • Patent number: 5894272
    Abstract: Apparatus for lighting and/or indicating purposes, on a vehicle such as a motor vehicle that has a rear fog lamp. The apparatus includes an electrical supply and a control circuit connecting the electrical supply to the fog lamp and/or an indicator. The control circuit is responsive to activating signals from a fog detector that is adapted to produce the activating signal when a condition of reduced visibility exists in the environment of the vehicle. This activating signal, moreover, is generated in response to electromagnetic waves reflected to a receiver coupled to the fog detector.

  • Patent number: 5589730
    Abstract: A lighting and/or indicating apparatus for a motor vehicle, of the type comprising an external light transmitting element and a base arranged behind the latter, typically consists of a lighting and indicating cluster. The light transmitting element comprises an outer panel, the base comprises an inner wall, and the two walls together constitute a thin gas-tight envelope and define at least one closed cavity. This cavity, or each cavity, contains two electrodes and a suitable gas under low pressure, the apparatus having means for applying voltage for starting and maintaining a luminescent gas discharge in the cavity, so that the envelope itself constitutes at least one light of the gas discharge type. The appearance and light output are improved, and the light beams emitted are highly homogeneous.
