| description | A lighting device is provided that has a light source arrangement with a plurality of semiconductor-based light sources in the form of light-emitting diodes. The light sources are bundled or collimated such that they each emit light in differently directed light cones with adjacent light cones overlapping. The lighting device has an adjusting device for adjustment of the direction of illumination and an actuating circuit connected to the adjusting device. The adjusting device adjusts intermediate stages for which the light-emitting diodes of adjacent and overlapping light cones operate and with varying light intensity in such a way the focal point of the light field produced by the light-emitting diodes lies between the focal points of adjacent light cones. |
