LIGHTING SYSTEM FOR CHANGING THE EMISSION CHARACTERISTICS

The invention relates to a lighting system for at least one light-emitting means (), in particular for light-emitting diodes, comprising a light fixture (), in which the light-emitting means () and mechanical components like a housing, cooling element, reflector, etc. are located; comprising a convertor () for operating the light-emitting means (); comprising an operating unit () having a charge storage (), like a smart phone, for example, for changing a mode of operation of the lighting system (), wherein in a first mode of operation, light is emitted across a first light exit surface by the lighting system (), and in a second mode of operation, light is emitted across a second light exit surface, wherein the first light exit surface and the second light exit surface have different light emission characteristics.
