Abstract

The invention relates to a spotlight (40) comprising a holder (13) for a light source (14), and a reflector (41) which at least partially surrounds the holder (13) and forms a light outlet (42) and is used to focus the light emitted by the light source (14). The arrangement of the holder (13) in relation to the reflector (41) can be varied in the light-emitting direction. The reflector (41) is split into a head reflector (5) surrounding the holder (13) and a main reflector (11) which is connected to the head reflector (5) in the light-emitting direction and forms the light emitting opening (42). The holder (13) can be displaced in relation to the two reflector parts (5, 11), and the arrangement of the two reflector parts (5, 11) in relation to each other can vary in the light-emitting direction.
