Abstract
Steerable focus essentially characterized by being constituted from a substantially spherical screen attached to a support arm with the possibility of diametral rotation, support arm that describes an arched path, concentric with the spherical screen itself and with an angular amplitude of 90º, finishing said arm support in a radial section through which joins, also articulately, to the corresponding fixed support, such as a terminal strip, ceiling or similar, with the particularity that said spherical screen is constituted by two removable parts, in one of the which is defined an embouchure, obtained by the imaginary elimination of a spherical cap, to which the corresponding parabola housed in the bosom of the screen is fitted, provided with the corresponding lampholder, inside which also establishes a transformer that converts the voltage of the network required by the type of bulb provided for the bulb, specifically a 12 volt halogen bulb.
