Abstract: An illumination device has an illumination means formed by an arrangement of a plurality of semiconductor light sources (2) grouped together to form a field. Sensor elements (3) are arranged at individual positions of the field instead of the semiconductor sources (2). A multifunctional headlight can thus be advantageously created. The headlight can be embodied as a robust, compact, low-space unit. By virtue of the fact that the light sources (2) and the sensor elements (3) do not necessarily use the same lens system (1) i.e. each individual element of the multifunctional headlight can be provided with an individually designed lens system (1), the beam path of the illumination device can be separated from the field of vision of the sensor system and can thus be determined independently over large areas.

Abstract: The invention relates to a wideband illumination device comprising a plurality of semiconductor light sources arranged in a field as a light source, for obtaining a specified light distribution for a vehicle headlight in different operating conditions. Parts of the semiconductor light sources are able to emit light in the visible wavelength region, while others emit light in the non-visible wavelength region. In an especially advantageous manner, individual optical elements are associated with the semiconductor light sources, either individually or in groups, for the targeted production of different radiation characteristics. One such wideband illumination device can be used to create a compact individual headlight by which means both the immediate vicinity and the main beam region in front of a motor vehicle can be illuminated with visible light. The same headlight can also be used to provide light in the non-visible region for using with systems for improving night vision.

Abstract: The invention relates to a novel projector which has an asymmetrical illumination characteristic, and a clear light-dark limit, and uses almost the entire radiation power outputted from the semiconductor light source. To this end, the projector consists of a field of individual semiconductor light sources which are provided with optical elements having a novel form. Said optical elements have as flat a form as possible, such that the light admission inlet of the optical element has an elongated, essentially rectangular form. Furthermore, the optical elements comprise a central region, perpendicular to the light admission surface (F), the projection of said central region into a two-dimensional plane corresponding to a cylindrical two-dimensional Cartesian oval. According to the invention, in order to better use the light emitted from the semiconductor light source, the light emergence surface (G) of the optical element, in the form of a Cartesian oval, is combined with a parabolic reflector (A, B).

Abstract: In order to improve road safety, modern vehicles are provided with sensor systems, which assist the driver of the vehicle either directly or indirectly with respect to the environment surrounding said vehicle, especially with regard to early recognition of dangerous situations, in addition to the usual illumination device. Said systems more particularly include radar systems for detecting distance and the relative speed of objects or night vision improvement systems which are based on illumination of the field of the road environment with infrared light. According to the invention, the illumination means of the illumination device are formed by an arrangement of a plurality of semiconductor light sources (2) grouped together to form a field. Sensor elements (3) are arranged at individual positions of said field instead of said semiconductor sources (2). A multifunctional headlight can thus be advantageously created. Said headlight can be embodied as a robust, compact, low-space unit.
