Abstract: The present invention relates to a device for illumination or signaling, comprising at least two light-emitting diodes that each emit a light beam and are supplied with a pulsed current so as to be lit alternately, the pulses of the supply current of the light-emitting diodes having an instantaneous intensity higher than the maximum intensity in steady state and an average intensity lower than this maximum value, the pulses of the supply current of the light-emitting diodes having a duty ratio greater than or equal to the inverse of the number of light-emitting diodes.

Abstract: An apparatus for lighting or indicating purposes in a motor vehicle includes a light guide associated with at least one light source for transporting light rays emitted by the light source from an input face to an output face via an intermediate section of the light guide. The output face of the light guide is contained between two closed lines which define a continuous internal contour and a continuous external contour, and the input face is contained between two further closed lines, also delimiting continuous internal and external contours.

Abstract: An indicator light for a motor vehicle includes a divider screen adapted to divide a light beam into a plurality of elementary light beams which are then added together downstream of the dividing screen. A first coloring means, for coloring some of the elementary light beams, is located at a distance from the divider screen. The light unit includes a second coloring means adapted to color at least some of the elementary light beams, the second coloring means being spaced away from the divider screen and the first coloring means.

Abstract: The present invention relates to an illuminating or indicating device, including at least two light sources, each light source being associated with a first optical system.

Abstract: A motor vehicle indicator light has an elongate light source, highly inclined with respect to a required beam spread direction and a reflector in which the source is mounted. The reflector includes a mirror able to create, from part of the source situated opposite it, a primary virtual light source parallel to the required direction of spread and means for concentrating the light radiation coming from the said primary virtual source in the vicinity of a plane containing the required beam spread direction.

Abstract: An indicator light for a motor vehicle includes a light source and a reflector, which directs light from the light source in a forward direction on a first screen having lines of optical elements, which converge the light beam received from the reflector on a second screen in front of the first screen. The second screen includes, through at least part of its thickness, colored bands and translucent bands which are arranged alternately with each other over the height of the screen. In the first screen, the lines of optical elements are separated from each other by opaque colored bands, which are aligned with the colored bands of the second screen.
