Abstract

A lighting unit, especially for a lighting system is described and is characterized by a carrier section which has a flattened elongate cross-section which terminates in acute angles at both ends, with all functional elements being concentrated in the central part which always has the largest vertical dimension. Changes of the dimensions lead, as a result of the selected layout to no substantial change in the outer appearance, so that powerful systems can also be realized with the same shape without impairing the external appearance.
