The invention relates among others to a lamp ( 10 ) for mounting on a building surface or a part of a building, like for example on a roof or a ceiling, a wall or a floor of a room, comprising a support device ( 12 ) or a plurality of light emitting diodes ( 29 ) and a light fitting element ( 21 ) which has a light entry area ( 28 ) adjoining the support device ( 12 ) for light which is supplied by the light emitting diodes ( 29 ), a light output area ( 30 ) and a light guide segment ( 27 ) which connects the light entry area ( 28 ) and the light output area ( 30 ) with one another. The particular subject matter of interest resides in that the light guide segment ( 27 ) has curved internal surfaces ( 30 ) and that the light is passed from the light entry area ( 28 ) to the light output area ( 30 ) through the light guide segment ( 27 ) basically with a multiplicity of reflections on the internal surfaces ( 20 ).
