Abstract
The headlight has a light source (10) and a reflector (12) by which light is reflected to a light guiding or deflecting device (18). The light guiding device (18) has a number, advantageousely from a few hundred to a hundred thousand, of individual reflecting elements (22) which are movable independently of each other between at least two different positions. Each reflecting element (22) is connected with an electrically operable adjusting element (26) which is controlled by a controller (30). The light reflected from the reflector (12) is reflectable from the light guide device (18) to form a light beam issuing from the lighting device. Reflected light from each reflecting element (22) in one of its positions forms a part of the light beam and does not contribute to the light beam in one of its other positions. Predetermined portions of the light beam can be switched on or off by controlling the individual light reflecting elements (22) and thus can change the characteristics of the light beam issuing from the lighting device.
