Abstract
The present invention relates mainly to a lighting and signalling device including at least one luminous module capable of generating a lighting beam along a longitudinal optical axis and an optical element through which the lighting beam is projected. The lighting and signalling device includes a controllable liquid-crystal screen pressed against the optical element, the controllable liquid-crystal screen being capable of adopting different diffusion states, including at least one state of projection of the lighting beam in which the controllable liquid-crystal screen is transparent and a state of emission of a signalling beam in which the controllable liquid-crystal screen is at least partially diffusing.
Claims8
A luminous and signalling device comprising at least one luminous module adapted to generate a lighting beam along a longitudinal optical axis and an optical element through which the lighting beam is projected, the luminous module includes a main light source and an additional light source, the luminous and signalling device includes a controllable liquid crystal screen pressed against the optical element, the controllable liquid crystal screen being adapted to take on different diffusion states including at least a lighting beam projection state in which the controllable liquid crystal screen is transparent and a signalling beam emission state in which the controllable liquid crystal screen is at least partially diffusing, and the optical element includes an inner face in contact with the controllable liquid crystal screen, an opposite outer face and a peripheral edge connecting the inner face to the outer face, the additional light source being installed facing the peripheral edge of the optical element.
