Abstract: A luminous signalling device comprises a body made of transparent synthetic material, basically in the form of a plate having two larger faces set opposite one another, at least one of which carries an image. A plurality of LED devices of the SMD type which emit white light is coupled externally to at least one of the walls that define the peripheral edge of the aforesaid plate body. The arrangement is such that the rays of white light coming out of the LED devices undergo multiple total reflections within the plate body, which thus functions as a light guide. In areas corresponding to selected areas of the image, the face of the plate body is made up of diffusing optical elements designed to diffuse outwards the rays of light that are incident on said areas within the body.

Abstract: An infrared sensor device for motor-vehicles, designed to detect the presence of an overtaking vehicle, comprising at least two cells sensitive to infrared radiation, placed on one side of the reflecting plate on the outside rear view mirror of a motor-vehicle, behind focusing optics. Each cell emits a signal proportional to the infrared radiation it receives. An electronic circuit emits a global signal proportional to the difference between the signals emitted by the two cells, so that said global signal enables the presence of an overtaking vehicle to be distinguished from that of other vehicles travelling in the opposite direction, as well as avoiding false alarms due to electronic and electromagnetic noise.

Abstract: The radiation beam emitted by a polychromatic source of finite dimension is incident onto an array of microlenses which have the function of converging and dividing the beam into a plurality of microbeams directed towards a matrix containing colored microfilters. Once the microfilters have been passed, the radiation reaches a matrix of microchoppers which can be selected independently from each other by a controller, for generating images.

Abstract: The light radiation beam emitted by a source with finite dimension, integrated within a transparent plate, in contact therewith, is initially reflected inside the plate by a first reflecting or semi-reflecting planar surface towards a second planar reflecting surface. Both reflecting surfaces are constituted by portions with an irregular profile provided in the two faces of the transparent plate, without applying a reflective coating.

Abstract: A radiation beam emitted by a polychromatic source with finite dimension is initially corrected in its vergence and distribution by a reflector or a system which operates according to refraction, diffraction, total inner reflection, effects and is incident on a matrix of micro-lenses with a square, rectangular or any other cross-section, which have the function of converging the beam towards a matrix of colored micro-filters or image micro-cells. The micro-filters or the cells corresponding to different images are two or more for each single micro-lens which is present in the matrix of micro-lenses. The dimension of the colored micro-filters is such that they intercept partially or totally the converging polychromatic beam. The selection of the color or the images is obtained by interposing the desired color in the polychromatic light beam. A movement of the plate of micro-filters enables the color or the image to be changed.

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.
