Abstract
The invention relates to a lighting system for at least one light-emitting means (24), in particular for light-emitting diodes, comprising a light fixture (22, 43, 61), in which the light-emitting means (24) and mechanical components like a housing, cooling element, reflector, etc. are located; comprising a convertor (23) for operating the light-emitting means (24); comprising an operating unit (10) having a charge storage (11), like a smart phone, for example, for changing a mode of operation of the lighting system (20), wherein in a first mode of operation, light is emitted across a first light exit surface by the lighting system (20), 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.
