A lighting system comprises a light source (2), a liquid crystal dimmer plate (4) for scattering a desired quantity of light from the light source (2), and a control power supply (5) for controlling a light scattering rate of said liquid crystal dimmer plate (4), so that a light component, included in the light from the light source (2), transmitted through the liquid crystal dimmer plate (4) with no scattering is employed as illuminating light. -52-
L'invention se rapporte à un éclairage comprenant une source lumineuse (2), une plaque variateur de lumière à cristaux liquides (4) servant à disperser une quantité désirée de lumière émise par la source lumineuse (2), et une source de courant de commande (5) servant à commander la vitesse de dispersion de la lumière de la plaque à cristaux liquides (4). La lumière émise par la source lumineuse (2), et qui traverse la plaque variateur de lumière à cristaux liquides (4) sans être dispersée, est utilisée pour éclairer.
