  • Spotlight and adjusting system
    Patent number: 4462067
    Abstract: The present invention provides a spotlight adjusting system for controlling the beam of a spotlight. A ellipsoidal reflector-lamp assembly is movable to a plurality of positions relative to the iris. The diaphragm of the iris is independently adjustable to a plurality of positions so that the light being reflected from the focal area of the reflector assembly can be controlled between passing the full beam received at the iris to a portion of the beam received there. The rear lens is adjustable relative to the iris and the front lens. The system provides mounting structures for both a long throw and a short throw front lens so that the system can be selectively mounted with either a removable long or short focal front lens.
