Abstract
A stage lighting fixture includes a casing; a light source, which is housed inside the casing and is adapted-to emit a light beam along an optical axis; a reflector coupled to the light source; light beam processing means housed inside the casing and adapted to selectively intercept the light beam; at least one heat-shield assembly located inside the casing, between the light source and the light beam processing means, to substantially divide the casing into a first area comprising the light source and the reflector, and a second area comprising the light beam processing means; the heat-shield assembly comprising a heat-shield filter, and a detector for detecting a parameter indicative of the temperature of the heat-shield filter; a cooling assembly for cooling the inside of the casing; a control device configured for regulating the cooling assembly on the basis of the parameter detected by the detector.
