ABSTRACT:
A multi-purpose visual signaling device, particularly for road emergency warning and in low visibility conditions, includes light-emitting means for generating a light beam and means for supplying power to the light-emitting means. The light-emitting means include at least one laser projector adapted to project images over a substantially flat surface for such images to be visible from a relatively long distance. The light-emitting means and the power supply means are mounted onto a stationary support structure, which may include a front warning triangle-defining portion. The laser projector comprises at least one laser diode and optical and/or electronic means for generating images in space or over a substantially flat surface. The optical and/or electronic means comprise a diffractive lens. Images include monochromatic, polychromatic and/or holographic images, possibly of variable configuration, and preferably form a triangular design.
