ABSTRACT:
A lighting device comprising one or more light sources placed inside a main reflector, with the light emitted by the light source(s) being reflected by the reflector so as to create a projected pattern of light to be directed onto a subject to be illuminated, a focusable light being achieved by shifting means capable of displacing the light source(s) with regard to the optical axis of the reflector. Said shifting means are apt to displace said at least one light source in a direction to and from said optical axis of said reflector, in a plane substantially perpendicular to said axis. The light source(s) is (are) placed around said optical axis of the reflector and are movable in a radial direction with regard to the optical axis of said reflector.
