发明名称 Light projector
摘要 A light projector for providing uniform surface area illumination of the type utilized in motion picture studios or the like, employs a housing having a reflector arranged at one end and a Fresnel lens arranged at the other end. At least two linear light sources are located in the interior of the projector at right angles to the optical axis and are electrically connected to a three-phase energization circuit. The lamps are arranged in a star-shaped pattern, relative one to another, and each is a single, self-operating, interchangeable unit, such that by replacing only one of the lamps in the light projector the color temperature of the illumination may be maintained approximately at the desired value.
