Problems solved by technology

This phenomenon leads to uncontrolled overheating of the light source, which often leads to irreversible damage of the light source
[0009] This means unreliability of the lighting fixture and obvious inconvenience to the end user

Embodiment Construction

[0022] exist figure 1 Among them, reference numeral 1 represents stage lighting equipment, which includes a housing 2, a light source 3, a reflector 4, a lens 5, a frame 6 coupled with the housing 2, and a beam processing device 7 (in figure 1 shown schematically in), the heat shield assembly 8 (in figure 1 Schematically shown in ), the cooling assembly 9 and the control device 10 .

[0023] The housing 2 extends along a longitudinal axis A and, along the axis A, has a closed end 11 and an open end 12 opposite the closed end 11 . Preferably, the housing 2 is supported by a supporting device (not shown in the drawings for simplicity). In particular, the support means and the housing 2 are configured to allow rotation of the housing 2 about two orthogonal axes, commonly referred to as PAN and TILT.

[0024] The frame 6 consists of elements coupled to each other and configured to define a support structure for elements accommodated in the housing 2, such as the light source 3,...

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.

Description

technical field [0001] The present invention relates to a stage lighting fixture. Background technique [0002] A known stage lighting fixture is provided with a housing, a light source adapted to emit a light beam, a reflector coupled to the light source, and at least one beam processing element (such as a dichroic filter) adapted to selectively intercept the light beam for processing the light beam. shutter, shutter, dimmer). [0003] A heat shielding filter is arranged between the light source and the beam processing element, which filter substantially divides the housing into a first region containing the light source and a second region containing the beam processing element. [0004] Lighting fixtures of this type are described, for example, in documents US4890208 and US5515254. [0005] The area including the light source is characterized by high temperatures and is typically cooled by a cooling assembly comprising at least one fan arranged near the air outlet to he...
