The invention relates to a projector for theatres, television studios, exhibition centres or the like, comprising an illumination means (2) enabling light to be produced and radiated, an optical device (7) having a plurality of lenses (10, 13, 15, 17) and by which means the beam path of the light radiated from the illumination means (2) can be influenced, a projector housing (19) in which the illumination means (2) and the optical device are arranged (7) and which comprises a light radiating surface (20), and a colour filter device (22) which is arranged in the light radiating surface (20) of the projector housing (19). In order to ensure that no unacceptable temperatures occur in the region of the colour filter device, an infrared reflection coating (28) is arranged between the illumination means (2) and the colour filter device (22) situated in the light radiating surface (20) of the projector housing (19), in the beam path of the light.
