Patent ID: 8894248

Claim:
A stage lighting fixture comprising: a casing ( 2 ); a light source ( 3 ) which is housed inside the casing ( 2 ) at a first end ( 11 ) of the casing ( 2 ) and is adapted to emit a light beam along an optical axis (B); a reflector ( 4 ) coupled to the light source ( 3 ); light beam processing means ( 7 ) housed inside the casing ( 2 ) and adapted to selectively intercept the light beam; at least one heat-shield assembly ( 8 ) located inside the casing ( 2 ), between the light source ( 3 ) and the light beam processing means ( 7 ), to substantially divide the casing ( 2 ) into a first area ( 36 a ) comprising the light source ( 3 ) and the reflector ( 4 ), and a second area ( 36 b ) comprising the light beam processing means ( 7 ); the heat-shield assembly ( 8 ) comprising a heat-shield filter ( 31 ), and a detector ( 37 ) for detecting a parameter indicative of the temperature of the heat-shield filter ( 31 ); a cooling assembly ( 9 ) for cooling the inside of the casing ( 2 ); a control device ( 10 ) configured for regulating the cooling assembly ( 9 ) on the basis of the parameter detected by the detector ( 37 ).
