  • Lighting system with a micro-telescope integrated in a transparent plate
    Patent number: 5841596
    Abstract: The light radiation beam emitted by a source of finite dimension, integrated in a transparent plate or in contact therewith, is initially reflected inside the plate by a first surface located on the side of the plate (3) which is more remote from the source. The reflected light rays pass through plate and are again reflected by a second surface having micro projections and then directed outwardly, according to a micro-telescope arrangement.
    Type: Grant
    Filed: September 25, 1996
    Date of Patent: November 24, 1998
    Assignee: C.R.F. Societa' Consortile per Azioni
    Inventors: Piero Perlo, Luca Sardi, Sabino Sinesi
  • Antireflection surface having a predetermined roughness, particularly for motor-vehicle dashboards
    Patent number: 5817396
    Abstract: An antireflection surface having a predetermined roughness so as to keep the reflectivity of incident radiation low. A profile with projections having a height which is an integer multiple of the radiation wavelength can trap the radiation irrespective from its polarization and also at large angles of incident light.

  • Devices with micro-mirrors and micro-filters for selecting colors and images
    Patent number: 5818627
    Abstract: The polychromatic or monochromatic radiation beam emitted by a light source strikes an array of micro-filters which partially or totally transmit the light beam towards an array of micro-mirrors. The partially reflected beam comes back towards the first array of micro-filters and passes again through it until it reaches a viewer or a recording system or a screen. A relative movement between the two arrays of micro-filters and micro-mirrors enables static or animated images or colour strips selectable according to the needs to be generated.
