Poor visibility at night is a stressful and dangerous situation, dreaded by many drivers. The frequency of accidents is decidedly higher at night as a result of poor visibility, compared with driving during the day and with good visibility. An improvement of visibility at night is achieved by using systems which, in addition to the normal headlights, have two "laser headlights" which use laser diodes emitting in the near infrared range as a light source. In order to minimize the space requirement for the laser headlights in addition to the normal headlights, a device is described in which, in an inventive way, the light beam used for lighting is deflected by a deviating prism and a reflector. It is conceivable to design the device such that the reflector emits the light beam in a direction which is rotated by approximately 90 degrees with respect to the direction of incidence of the light beam into the deviating prism. It is possible in this way to place the light source or the light beam supply directly behind the reflector, thereby creating a flat, space-saving structure in the lighting device by using a bent beam path. However, the device is also suitable for stationary applications, in particular in or on buildings.
