a light source (12) which is disposed in the light space (11); a housing (13) which delimits the light space (11) and extends in the light output direction; a main reflector (14) which delimits the light space, extends transversely with respect to the light output direction and, relative to the light output direction, is disposed upstream of the light source (12); an output optical unit (15) which is disposed at a light exit side of the light space (11) and, relative to the light output direction, is disposed downstream of the light source (12) and outputs the light of the spotlight (1); an auxiliary reflector (16), wherein the auxiliary reflector (16) is disposed movably, such that it can be positioned at least at a first position between the main reflector (14) and the light source (12) or at a second position between the light source (12) and the output optical unit (15). ## Claims ### Claim 1 A spotlight for illuminating a film, studio, stage, event and/or theatre environment, comprising: a light space having an optical axis which defines a light output direction; a light source disposed movably in the light space; a housing which delimits the light space and extends in the light output direction; a main reflector which delimits the light space, extends transversely with respect to the light output direction and, relative to the light output direction, is disposed upstream of the light source; an output optical unit which is disposed at a light exit side of the light space and, relative to the light output direction, is disposed downstream of the light source and outputs the light of the spotlight; and an auxiliary reflector, wherein the auxiliary reflector is disposed movably, such that it can be positioned at least at a first position between the main reflector and the light source or at a second position between the light source and the output optical unit, wherein the output optical unit can be reconfigured between a first configuration corresponding to the first position of the auxiliary reflector and a second configuration corresponding to the second position of the auxiliary reflector. ### Claim 2 A spotlight for illuminating a film, studio, stage, event and/or theatre environment, comprising: a light space having an optical axis which defines a light output direction; a light source disposed movably in the light space; a housing which delimits the light space and extends in the light output direction; a main reflector which delimits the light space, extends transversely with respect to the light output direction and, relative to the light output direction, is disposed upstream of the light source; an output optical unit which is present in a first configuration and is disposed at a light exit side of the light space and, relative to the light output direction, is disposed downstream of the light source so as to be able to be removed and which, if mounted, outputs the light of the spotlight; and an auxiliary reflector, wherein the auxiliary reflector is disposed movably, such that it can be positioned at least at a first position between the main reflector and the light source or at a second position between the light source and the output optical unit. ### Claim 3 (depends on 1) The spotlight as claimed in claim 1, wherein the spotlight having the auxiliary reflector located at the first position and the output optical unit present in the first configuration function as a wide-angle spotlight. ### Claim 4 (depends on 1) The spotlight as claimed in claim 1, wherein the spotlight having the auxiliary reflector located at the second position and the output optical unit present in the second configuration, or the removed output optical unit functions as a narrow-angle spotlight. ### Claim 5 (depends on 1) The spotlight as claimed in claim 1, wherein the main reflector is at least one of textured and faceted. ### Claim 6 (depends on 1) The spotlight as claimed in claim 1, wherein the output optical unit in the first configuration comprises a Fresnel lens (152). ### Claim 7 (depends on 1) The spotlight as claimed in claim 1, wherein a half-peak divergence of the emitted light is either in the range less than 10° or in the range greater than 10°. ### Claim 8 (depends on 1) The spotlight as claimed in claim 1, wherein the auxiliary reflector is disposed in such a manner that a light spot of the light source is located in a center of curvature of the auxiliary reflector. ### Claim 9 (depends on 1) The spotlight as claimed in claim 1, wherein the auxiliary reflector has a diameter which is dimensioned such that all beams from the auxiliary reflector impinge upon the main reflector. ### Claim 10 (depends on 1) The spotlight as claimed in claim 1, wherein the auxiliary reflector is at least one of concave at the first position and convex at the second position in relation to the light output direction. ### Claim 11 (depends on 9) The spotlight as claimed in claim 9, wherein the auxiliary reflector at the first position is more concavely curved than the main reflector in relation to the light output direction. ### Claim 12 (depends on 1) The spotlight as claimed in claim 1, wherein the auxiliary reflector at the first position reflects at least a part of the light emitted by the light source to the output optical unit. ### Claim 13 (depends on 1) The spotlight as claimed in any claim 1, wherein the auxiliary reflector at the second position is configured as a counter-reflector and is designed to reflect at least a part of the light emitted by the light source back to the main reflector. ### Claim 14 (depends on 1) The spotlight as claimed in claim 1, wherein the auxiliary reflector can be at least one of rotated and pivoted 180° about the light source. ### Claim 15 (depends on 13) The spotlight as claimed in claim 13, wherein the rotating or pivoting can be effected azimuthally at least one of above, below, and along the optical axis. ### Claim 16 (depends on 1) The spotlight as claimed in any claim 1, wherein the auxiliary reflector is disposed at the first position entirely between the main reflector and the light source or is disposed at the second position entirely between the light source and the output optical unit. ### Claim 17 (depends on 1) The spotlight as claimed in claim 1, wherein the light source is disposed so as to be able to move in a direction at least one of along and transverse with respect to the optical axis. ### Claim 18 (depends on 1) The spotlight as claimed in claim 1, wherein the light source and the auxiliary reflector are disposed on a common carrier, and optionally wherein at least one of: the carrier comprises a pivot wherein the pivot allows selective positioning of the auxiliary reflector at the first position or at the second position; and/or the light source is disposed in a positionally fixed manner in relation to the carrier; and/or the carrier is disposed so as to be movable in a direction in parallel with the optical axis; and the auxiliary reflector is disposed movably on the carrier so that a distance along the optical axis between the auxiliary reflector and the light source can be variably adjusted within an adjustment range. ### Claim 19 (depends on 1) The spotlight as claimed in claim 1, wherein the light source includes a halogen-metal vapor lamp or a tungsten halogen lamp. ### Claim 20 (depends on 1) The spotlight as claimed in claim 1, wherein the housing couples the output optical unit to the main reflector.
